Description
Technical Field
The present invention relates to a basket, a top lacing system, a connecting structure basket, and a child safety seat.
Background
The basket can be applied to vehicles and airplanes, and provides safety guarantee for the travel of infants. When the basket is applied to a vehicle, the basket is detachably connected with a base mounted to a seat of the vehicle. The base may be secured to the vehicle seat by an ISOFIX system or a LATCH system, and the base may also be secured to the vehicle seat by a three-point vehicle seat belt of the vehicle seat. Because the frequency of the basket applied to the vehicle is far higher than that of the basket applied to the airplane, the prior basket is not provided with a structure for positioning the vehicle-mounted safety belt in order to avoid the problem that the user wrongly winds the vehicle-mounted safety belt on the basket to cause the fixing failure of the base. When the basket needs to be applied to an aircraft seat, the basket is difficult to connect and position with a safety belt of the aircraft seat.
Some existing child safety seats (including seat bodies and seats) require additional securement by a top strap in addition to the ISOFIX points that are secured to the vehicle. The top harness is generally integrally fixedly attached to the seat body. However, the inventors of the present application have found that child safety seats having top straps fixedly attached to the seat body add weight to the seat body, and do not facilitate the removal of the seat body from the base and use alone, such as when the seat body is used alone as a basket, it is laborious for the user to lift the basket.
In order to connect the child safety seat to the associated fitting, it is necessary to provide a connection structure in the child safety seat to connect the fitting, for example, to provide a connection structure to connect with a roof strap to more securely fix the child safety seat to the vehicle seat via the roof strap. Therefore, it is necessary to design a connection structure.

In the embodiment of the present invention, the terms of the directions of the basket 1100 such as "front", "rear", "left" and "right" are based on the directions of the child sitting in the basket 1100, and the directions of the basket 1100 such as "front", "rear" and "left" are schematically shown by arrows F1 and B1, and the directions of the basket 1100 such as "left" and "right" are schematically shown by arrows L1 and R1. These directional terms are used only to make the description of the embodiments of the present invention clearer and are not used to unduly limit the scope of the present invention.
Referring to fig. 1 and 3, the base 1200 may be placed on a vehicle seat (not shown) and provide firm support for the basket 1100. The base 1200 may include a base 1091, a post 1092 mounted on the base 1091, and a connector 1093. The seat 1091 is for mounting on a vehicle seat (not shown), and the body 1001 of the basket 1100 is detachably mounted on the seat 1091. The base 1091 may be provided with a locking mechanism 1911, the body 1001 of the basket 1100 may be locked to the base 1091 by the locking mechanism 1911, and the body 1001 of the basket 1100 may be removed from the base 1091 when the locking mechanism 1911 is released.
A push rod 1092 extends upward from the rear end of the seat body 1091, and the push rod 1092 is for abutting against the backrest of the vehicle seat. The connector 1093 is mounted at the rear end of the seat 1091, and the connector 1093 can be plugged into a universal plug on the vehicle seat. The connector 1093 may be an ISOFIX connector or a LATCH connector. In some embodiments, holes 1910 may be provided on both left and right sides of the rear end of the seat 1091, and a male buckle of a three-point seat belt that mates with a vehicle seat may pass through the hole 1910 on one side and then out the hole 1910 on the other side, and then connect with a plug-in port on the vehicle seat. In other embodiments, a top strap (not shown) may be mounted to the base 1091 or basket 1100 and may be connected to an anchor point behind the vehicle seat after passing over the vehicle seat.
In the embodiment of the present invention, the terms "front", "rear", "left", "right", and the like of the base 1200 refer to the "front", "rear", "left", and "right" orientations of the vehicle when the base 1200 is mounted to the vehicle seat. And the "front", "rear" directions of the base 1200 are schematically shown by arrows F2, B2, and the "left", "right" directions of the base 1200 are schematically shown by arrows L2, R2. These directional terms are used only to make the description of the embodiments of the present invention clearer and are not used to unduly limit the scope of the present invention.
Referring to fig. 1, the basket 1100 is mounted on the base 1200, for example, in a rearward manner, with the view of a child seated in the basket 1100 directed toward the rear of the vehicle. It will be appreciated that the front-back, left-right direction of the basket 1100 mounted to the base 1200 in a backward manner is opposite to the front-back, left-right direction of the base 1200.
With continued reference to fig. 1, the side 1001a of the basket 1100 is provided with the engagement member 1002 and the cover 1311, more specifically, the engagement member 1002 and the cover 1311 are located outside of the left and right sides of the basket 1100. In fig. 1, a portion of the joint 1002 covered by the cover 1311 is shown with a broken line. Referring to the top view of the basket 1100 shown in fig. 4, the engagement member 1002 defines a channel structure 1020 for engaging with an external seat belt (see fig. 6, for example, a seat belt of an aircraft seat, hereinafter referred to simply as seat belt 1300), the channel structure 1020 having an engagement opening 1201, the engagement opening 1201 allowing the seat belt to enter or exit the channel structure 1020. Cover 1311 has a first mode of operation and a second mode of operation. In the first mode of operation, the cover 1311 covers at least a portion of the engagement member 1002, and more specifically, at least a portion of the engagement opening 1201 such that the engagement opening 1201 is completely or partially covered by the cover 1311, thereby restricting entry of an outside seat belt (a seat belt of a vehicle seat, hereinafter simply referred to as a vehicle seat belt) into the groove-shaped structure 1020, effectively avoiding erroneous engagement of the vehicle seat belt with the groove-shaped structure 1020 (see fig. 5). In the second mode of operation, cover 1311 releases the cover from engagement opening 1201 and allows the harness to enter into channel 1020, and harness 1300 passing through channel 1020 can easily secure basket 1100 to the aircraft seat (see fig. 6).
According to the basket 1100 provided by the embodiment of the invention, the cover piece 1311 is switched to the first working mode or the second working mode, so that the basket 1100 can be switched to the first using mode or the second using mode. The first mode of operation of the cover 1311 corresponds to a first mode of use of the basket 1100, and the second mode of operation of the cover 1311 corresponds to a second mode of use of the basket 1100. The basket 1100 is adapted for use in a vehicle when in a first mode of use, and may be mounted to a vehicle seat by the base 1200. At this time, the cover 1311 in the first operation mode can prevent the vehicle seat belt from entering the groove structure 1020 through the engagement port 1201, and can effectively avoid the fixing failure of the base 1200 caused by the user erroneously installing the vehicle seat belt into the groove structure 1020. In a second mode of use, the basket 1100 is adapted for use in an aircraft, the basket 1100 being placed, for example, directly on an aircraft seat (not shown). At this time, the cover 1311 in the second mode of operation releases the cover of the engagement opening 1201 and allows the seat belt to enter the channel 1020, pass through the channel 1020 and securely mount the basket 1100 to the aircraft seat.
Referring to fig. 2,4 and 5, an exemplary embodiment of the joint 1002 is shown, the joint 1002 may include a connection 1021 and an extension 1022. The connection portion 1021 extends outwardly from the side portion 1011 of the body 1001. More specifically, the connection 1021 may extend laterally outward (e.g., in the R1-L1 direction in FIG. 4) from the outer side surface of the side wing 1015. The extension 1022 extends from the outer end 1211 of the connection 1021 in the front-rear direction of the basket 1100 (e.g., in the direction B1-F1 in fig. 4). The extending direction S-S of the extending portion 1022 is not parallel to and not coincident with the extending direction T-T of the connecting portion 1021, i.e., an included angle (e.g., 90 degrees) is formed between the extending direction S-S and the extending direction T-T. Referring to fig. 5, the extending direction S-S of the extension 1022 is not limited to the front-rear direction parallel to the horizontal plane, and in some embodiments, the extending direction S-S of the extension 1022 may be the front-rear direction inclined with respect to the horizontal plane. In some embodiments, the engagement member 1002 may be integrally formed with the plastic housing of the body 1001. In some embodiments, the engagement member 1002 may be mounted to the body 1001, for example, by a fastener (e.g., a screw).
Referring to fig. 4, the connection 1021, the extension 1022, and the side 1011 of the body 1001 collectively define a channel structure 1020. An end of the extension 1022 remote from the connection 1021 and the side 1011 of the body 1001 form an engagement 1201 of the channel 1020. As previously described, the engagement opening 1201 allows the harness 1300 to enter or exit the slotted structure 1020 to allow the basket 1100 to be secured to or removed from an aircraft seat.
Of course, the embodiment of the engagement member 1002 is not limited to the above example as long as it can form a groove-type structure 1020 for engagement with the webbing and having the engagement port 1201. For example, in some alternative embodiments, the direction of extension S-S of the extension 1022 may be perpendicular to the horizontal plane. In addition, although the extending direction T-T of the connecting portion 1021 and the extending direction S-S of the extending portion 1022 are substantially perpendicular to each other to form an included angle of 90 degrees in fig. 4 and 5, in some alternative embodiments, the extending direction T-T and the extending direction S-S may form an obtuse included angle or an acute included angle, for example. Further, in some alternative embodiments, the joint 1002 may include a base portion (not shown) connected to the connection portion 1021 and opposite the extension portion 1022, the base portion being mounted on the side 1011 of the body 1001. The base portion, the connection portion 1021, and the extension portion 1022 together define a channel structure 1020, and an end of the extension portion 1022 remote from the connection portion 1021 forms an engagement opening 1201 of the channel structure 1020 with the base portion. Furthermore, in some alternative embodiments, the engagement member 1002 may be a hollow closed structure, such as a closed annular structure (not shown), with the hollow channels of the closed annular structure forming the channel-type structure 1020 and the ports of the hollow channels forming the engagement openings 1201.
Referring to fig. 1, 5, and 6, an exemplary embodiment of a cover 1311 is shown. In fig. 5, a portion of the joint 1002 covered by the cover 1311 is shown with a broken line. In this embodiment, the cover 1311 comprises, for example, a seat cloth 1003, and the seat cloth 1003 may include a skirt 1031 folded from an upper edge of the side wing 1015 of the body 1001 toward an outer side surface of the body 1001, the skirt 1031 being for covering the joint 1002 and the joint 1201. The cover 1311 (more specifically, the skirt 1031) is provided with a first opening 1301 corresponding to the position of the joint 1002. When the cover 1311 is in the first mode of operation, the skirt 1031 of the seat cloth 1003 covers the engagement opening 1201 to restrict the vehicle seat belt from entering the channel structure 1020. It will be appreciated that when the cover 1311 is in the first mode of operation, the skirt 1031 is supported away from the side 1011 of the body 1001 by the extension 1022 of the engagement member 1002. Referring to fig. 6, when cover 1311 is to be switched to the second mode of operation, extension 1022 of engagement member 1002 is adapted to pass through first opening 1301 to expose engagement opening 1201 out of the cover (more specifically, skirt 1031), and seat belt 1300 may be engaged with engagement member 1002 directly from engagement opening 1201 into channel structure 1020 to secure basket 1100 to the aircraft seat. It will be appreciated that in the second mode of operation, the skirt 1031 is closer to the outer side of the side 1011 of the body 1001 than the extension 1022.
It will be appreciated that when the cover 1311 is in the first mode of operation, the first opening 1301 is offset from the engagement opening 1201, the first opening 1301 being, for example, closer to the connection 1021 than the engagement opening 1201, so that the vehicle seat belt cannot pass directly into the engagement opening 1201 via the first opening 1301. In some embodiments, the first opening 1301 may be provided at a position corresponding to the connection portion 1021, for example. When the cover 1311 is switched to the second mode of operation, the engagement member 1002 passes through the first opening 1301. In the second mode of operation, the cover 1311 is placed over the first opening 1301, for example, over the connection 1021. In some embodiments, the skirt 1031 may be made of, for example, an elastic material having a relatively large elastic deformation so that the first opening 1301 may be relatively easily brought closer to the joint 1201 to facilitate the passage of the extension 1022 of the joint 1002 through the first opening 1301.
Referring again to fig. 5, in some embodiments, the first opening 1301 is, for example, a generally rectangular hole. In the extending direction of the joint 1002, more specifically, in the extending direction S-S of the extending portion 1022 of the joint 1002, the dimension S1 of the first opening 1301 is smaller than the dimension S2 of the joint 1002 in this direction, for example. In the height direction of the joint 1002 perpendicular to the extending direction S-S, the dimension H1 of the first opening 1301 is, for example, larger than the dimension H2 of the joint 1002 in this direction. This facilitates the passage of the engagement member 1002 out of the first opening 1301 along the extending direction S-S. Of course, the embodiment of the first opening 1301 is not limited to the embodiment shown in fig. 5, as long as the engagement member 1002 is allowed to protrude as needed.
Further, in some not shown embodiments, the first opening 1301 is, for example, a slit, which may extend along the extending direction S-S of the joint 1002, the slit having a dimension, for example, close to the dimension S2 of the joint 1002 along this direction, and a dimension, for example, in the height direction perpendicular to the extending direction S-S, of the slit being substantially smaller than the dimension H2 of the joint 1002 along this direction. In some embodiments, the slit may extend, for example, in a height direction perpendicular to the extending direction S-S, so long as the slit allows the joint 1002 to pass therethrough with the joint 1201 exposed. In some embodiments, cover 1311 (more specifically, skirt 1031 may be made of an elastic material such that first opening 1301 may be elastically enlarged, to avoid accidental passage of engagement member 1002 through the slit, seat cloth 1003 may also be provided with a closure member for closing the slit, for example, a velcro, zipper, snap, button, etc. the closure member may be, for example, a velcro, a zipper, snap, button, etc. when cover 1311 is in the first mode of operation, the closure member closes the slit such that engagement member 1002 cannot pass out of the slit and be covered by skirt 1031, and a vehicle seat belt cannot enter channel 1020. When cover 1311 is in the second mode of operation, the closure member opens the slit, engagement member 1002 may pass through the slit to expose engagement opening 1201 outside skirt 1031, and a seat belt may enter channel structure 1020 from engagement opening 1201 to engage engagement member 1002 to secure basket 1100 to an aircraft seat.
In the above embodiments, the cover 1311 is described as including the seat cloth 1003, and in some alternative embodiments, the cover 1311 may not include the seat cloth 1003, for example, the cover 1311 may be a fabric connected to the seat cloth 1003, for example, disposed outside the seat cloth 1003 and may be provided with the first opening 1301 described above. Cover 1311 may also be removably attached to body 1001 and/or seat cloth 1003 by any suitable positioning structure. The fabric cover 1311 may cover the engagement opening 1201 so as not to allow the vehicle seat belt to enter the channel 1020, and the engagement member 1002 may pass out of the first opening 1301 such that the engagement opening 1201 is exposed outside the cover 1311 to allow the seat belt 1300 to enter the channel 1020.
Fig. 7 and 8 illustrate yet another exemplary embodiment of a cover 1311, the cover 1311 being a variation of the cover 1311 illustrated in fig. 5 and 6. Specifically, the seat fabric 1003 includes, for example, a skirt 1031, at least a portion of the skirt 1031 forming a cover 1311, the cover 1311 not having the first opening 1301. Referring to fig. 7, in the first mode of operation, cover 1311, skirt 1031, for example, at least partially covers engagement member 1002 and engagement port 1201 and no vehicle seat belt is able to enter channel 1020. In fig. 7, a portion of the joint 1002 covered by the cover 1311 is shown with a broken line. A first positioning structure 1004 may be provided between the seat cloth 1003 and the body 1001, and more specifically, the first positioning structure 1004 may be provided between the skirt 1031 and the side 1011 of the body 1001. In the first mode of operation, the overlay 1311 is removably attached to the body 1001 by the first positioning structure 1004. Referring to fig. 8, when the cover 1311 needs to be switched to the second mode of operation, the first positioning structure 1004 releases the positioning of the seat cloth 1003, allowing the skirt 1031 to move upwardly to expose the engagement opening 1201, and the seat belt 1300 may enter the slot structure 1020 through the engagement opening 1201 to engage with the engagement member 1002 to secure the basket 1100 to the aircraft seat.
Referring to fig. 8, in some embodiments, the first positioning structure 1004 can include a first positioning member 1041 mounted to the skirt 1031 and a second positioning member 1042 mounted to the side 1011 of the body 1001 (more specifically, the outer side of the side 1011), the first positioning member 1041 and the second positioning member 1042 can be, for example, snaps or other suitable components that mate with one another.

Fig. 13 and 14 illustrate yet another exemplary embodiment of a cover. Cover 1311 is, for example, a strip made of fabric, including opposing first surface 1311c and second surface 1311d. Edges of the first surface 1311c and the second surface 1311d are, for example, sewn together to form a receiving space 1310a therebetween. The outline of the accommodation space 1310a is shown in broken lines in fig. 13 and 14. Of course, in other embodiments, the material of cover 1311 is not limited to fabric, nor is its shape limited to tape.
The first end 1311a of the cover 1311 is a fixed end that may be connected to the skirt 1031 of the seat cloth 1003 or the body 1001 by any suitable means. In this embodiment, the first end 1311a of the cover 1311 is sewn together, for example, with the skirt 1031. In other embodiments, the first end 1311a of the cover 1311 may be connected to a side 1011 or bottom of the body 1001, for example.
The second end 1311b of the cover 1311 is a free end. Referring to fig. 14, when the cover 1311 is in the second mode of operation, the joint 1002 is located above the first end 1311a of the cover 1311, and the second end 1311b of the cover 1311 naturally sags below the first end 1311 a. At this time, the cover 1311 is separated from the second joint 1002, the first surface 1311c of the cover 1311 is visible against the body 1001, and the second surface 1311d is not visible against the body 1001.

Fig. 32 is a perspective view of a fourth embodiment of a child safety seat 2100 according to the present invention. Fig. 33 is a state of the seat body 2110 when the seat body 2110 of the child safety seat 2100 according to fig. 32 is away from the base 2120. Fig. 36 is a state in which the seat body 2110 of the child safety seat according to fig. 32 is removed and the rear chassis 2120. In this embodiment, the first portion 2131 is secured to the seat body 2110 and the second portion 2132 is in a flexible strap-like structure (e.g., webbing). The first portion 2131 may be a non-flexible structure (e.g., a metallic structure), the first portion 2131 may also be a flexible structure (e.g., a fabric), and the first portion 2131 may have some elasticity so long as it is strong enough to cooperate with the second portion 2132 to securely fix the child safety seat 2100 in accordance with the present invention to a vehicle.
As shown in fig. 32, the second portion 2132 has a first end 2132a and two second ends 2132b, and the top lacing system further includes a first connector 2141 and two fourth connectors 2144, the first connector 2141 being disposed at the first end 2132a and adapted to connect to a vehicle, the two fourth connectors 2144 being disposed at the two second ends 2132b and being removably connected to each other, respectively.
Specifically, in order to more firmly connect the two fourth connecting members 2144 to each other in the stretched state of the second portion 2132 when in use, in this embodiment, one of the two fourth connecting members 2144 has a hook, and the other of the two fourth connecting members 2144 has a connecting hole, and the hook is snap-fitted with the connecting hole so that the two second ends 2132b of the second portion 2132 are quickly connected or detached. In some embodiments, the two fourth connectors 2144 may be hook and loop fasteners or snap fasteners. It should be noted that, in some embodiments, any one of the two fourth connectors 2144 may be selectively disposed, for example, the two second ends 2132b of the second portion 2132 are directly tied to each other in a flexible band structure, or one second end 2132b of the second portion 2132 is tied or fastened to the fourth connector 2144 disposed at the other second end 2132b (for example, the fourth connector 2144 in the form of a "japanese" button).
As shown in fig. 32 and 33, the second portion 2132 has a surrounding portion 2132e, the surrounding portion 2132e is configured to surround the back surface 2111 of the seat body 2110, and the first portion 2131 is penetrated by the surrounding portion 2132 e. Specifically, in the present embodiment, the second portion 2132 has a Y-shaped structure, i.e., two branches extend from the first end 2132a and form two second ends 2132b. In this embodiment, the surrounding portion 2132e of the second portion 2132 surrounding the back surface 2111 is provided on one of the branches, and when the top lacing system is installed in use, the second end 2132b of one of the branches of the second portion 2132 to which the hook or attachment hole is attached bypasses one of the side wings 2114 of the seat body 2110 and surrounds the back surface 2111 such that the surrounding portion 2132e passes from the back surface 2111 of the seat body 2110 through the first portion 2131, and then this second end 2132b is snapped around the other side wing 2114 of the seat body 2110 into engagement with the second end 2132b of the other branch. In the present embodiment, if the two side wings 2114 are considered to be connected to opposite sides of the back surface 2111 in the left-right direction, the connection position of the two fourth connection members 2144 is located at one side of the first portion 2131 in the left-right direction.
It should be noted that, in other embodiments, the surrounding portion 2132e of the second portion 2132 may be formed by two branches together, and it is understood that when the two second ends 2132b are connected to each other outside the back surface 2111, rather than the side wings 2114, the surrounding portion 2132e surrounding the back surface 2111 is formed by two branches together. For example, in an embodiment where each of the two branched surrounding portions 2132e is detachably connected at the back side of the first portion 2131 after passing through the first portion 2131 (both surrounding portions 2132e pass through the first portion 2131 at the same time), respectively, the first portion 2131 may be fixed to the middle position of the back side 2111 of the seat body 2110 so that both the first portion 2131 and the second portion 2132 can be connected to each other with a force balance. As another example, instead of being fixed in a middle position of the back surface 2111, the first portion 2131 is biased to one of the sides of the back surface 2111, i.e., if two side wings 2114 are considered to be connected to the left and right sides of the back surface 2111, the first portion 2131 is biased to the left side wing 2114 or the right side wing 2114 of the back surface 2111, where the two branches may together form a surrounding portion 2132e to surround the back surface 2111, with two second ends 2132b (or two fourth connecting portions 2144) of the two branches connected on one side of the first portion 2131, i.e., with two second ends 2132b (or two fourth connecting portions 2144) connected between the first portion 2131 and the right side wing 2114 or between the first portion 2131 and the left side wing 2114.
It will be appreciated that the two fourth connectors 2144 of this embodiment are configured to be detachably connected to the outer side of the first portion 2131 for user operation, wherein the "outer side of the first portion 2131" may be either one of the left or right sides or the back side of the first portion 2131.
As shown in fig. 36, the first portion 2131 has a mounting portion 2151a for mounting to the back surface 2111 of the seat body 2110 and a second fixed portion 2152a connected to the mounting portion 2151a, with a gap 2153a between the mounting portion 2151a and the second fixed portion 2152a, and a surrounding portion 2132e of the second portion 2132 passes through the gap 2153a. One end 2152c of the second fixed portion 2152a of the first portion 2131 is connected to the mounting portion 2151a of the first portion 2131, and the other end 2152e of the second fixed portion 2152a is suspended to form an opening in the first portion 2131. The second fixing portion 2152a of the first portion 2131 is provided with a blocking portion 2154a corresponding to the opening, and the blocking portion 2154a limits the surrounding portion 2132e of the second portion 2132 from being separated from the gap 2153a, so as to avoid accidental separation after the second portion 2132 and the first portion 2131 are connected to each other. That is, when the surrounding portion 2132e passes through the first portion 2131 from the back surface 2111 of the seat body 2110, the surrounding portion 2132e passes over the blocking portion 2154a from the other end 2152e of the second fixed portion 2152a of the first portion 2131 and enters the gap 2153a between the blocking portion 2154a and the mounting portion 2151 a. The shape of the blocking portion 2154a (e.g., the barb shape shown in fig. 36) is configured such that the surrounding portion 2132e is easily passed over the blocking portion 2154a into the gap 2153a, and is thereafter restrained by the blocking portion 2154a from being disengaged from the second securing portion 2152 a. The second fixing portion 2152a or the blocking portion 2154a has elasticity so that the surrounding portion 2132e can be disengaged from the gap 2153a by elastic deformation of the second fixing portion 2152a or the blocking portion 2154a when the seat body 2110 is detached from the base 2120. Of course, the manner of securing the first portion 2131 to the seat body 2110 is not limited thereto, and if the first portion 2131 is a flexible structure (e.g., fabric), the first portion 2131 may be secured directly to the corresponding fabric on the back side 2111 of the seat body 2110 by stitching or the like. That is, there are different embodiments of the first portion 2131 being secured to the seat body 2110, such as: the first portion 2131 is secured to the seat body 2110 for installation, such as by fasteners such as rivets or screws, or by a snap fit arrangement between the first portion 2131 and the seat body 2110 to the seat body 2110; or the first portion 2131 is secured to the seat body 2110 by an integral molding. It should be noted that the first portion 2131 is secured to the outside of the back side 2111 of the back rest portion 2113 of the seat body 2110 by a separate mounting or integral molding such that the top lacing system is applied without compromising the rigidity of the seat body 2110 (child protection).
Preferably, the first portion 2131 mounted to the seat body 2110 is located at a generally central portion of the back side 2111 of the back rest portion 2113 of the seat body 2110 so that the top strap system can force evenly secure the seat body 2110 to the vehicle when the child safety seat according to the present invention is used in the vehicle. The second portion 2132 having two second ends 2132b and one first end 2132a is a flexible strap-like structure of generally Y-shape, wherein the branch at which one second end 2132b is located is longer than the branch at which the other second end 2132b is located due to the surrounding portion 2132e (as shown in fig. 32, 37). That is, the length of one fourth link 2144 to the first end 2132a is greater than the length of the other fourth link 2144 to the first end 2132 a. The three branch junctions of the second portion 2132 form a central junction of Y-configuration (with the same stitching 2133 as in the previous embodiments) that also lies on a generally longitudinal plane of symmetry of the seat body 2110 when the roof lacing system is attached to the vehicle for use, so that the roof lacing system can force-evenly secure the seat body 2110 to the vehicle when the child safety seat according to the present invention is used in the vehicle.
In this embodiment, by providing two second ends 2132b of the second portion 2132 to be detachably connected, specifically, two fourth connecting pieces 2144 (hooks and connecting holes) are detachably connected to the side (side wing) of the seat body 2110, when the caretaker does not need to lift the seat body 2110, only needs to detach the hooks and the connecting holes when he wants to hold the baby away, he can hold the baby from the side of the seat body 2110, and keep the connection between the second portion 2132 and the first portion 2131, and then, when the baby is put into the seat body 2110 again, he does not need to connect the second portion 2132 to the first portion 2131, and only needs to connect the hooks of the second portion 2132 with the connecting holes, the webbing (the second portion 2132) is blocked from the path of the child entering and exiting the seat body 2110, so that the use is convenient. It should be noted that, in the fourth embodiment, the adjusting member 2170 is also provided, the second portion 2132 may also include an adjusting section 2132d and a connecting section 2132c, the ejector rod structure also includes an ejector rod 2121 and a connecting portion 2121c, and the specific manner in which these corresponding structures and the second portion 2132 are limited to the ejector rod structure are similar to those of the first embodiment, and are not repeated herein.
In addition, similarly to the first to third embodiments, in the present embodiment, the child safety seat 2100 according to the present invention can be taken out separately from the seat body 2110 (basket) after the first portion 2131 and the second portion 2132 are detached from each other, and is used to fix the child safety seat 2100 to the vehicle when the connection of the top tether system is completed. After the seat body 2110 of the child safety seat according to the present invention is lifted away, since the first portion 2131 is restricted from being detached from the seat body 2110 and the second portion 2132 in a flexible band-like structure can also be left on the base 2120 (the second portion 2132 is provided to pass through the through portion 2121b and restricted from being detached from the through portion), the first portion 2131 and the second portion 2132 can be prevented from being lost and the weight of the seat body 2110 (basket) can be reduced. The second portion 2132 is fixedly attached to the base 2120 not only so that the second portion 2132 is not lost, but also so that the base 2120 is once mounted to the vehicle seat and the second portion 2132 is attached to the vehicle (whether the seat body 2110 is moved away or back to be mounted again to the base 2120), this portion (the base 2120 and the second portion 2132 already mounted to the vehicle) does not require reinstallation for use.
It should be noted that, in each of the above embodiments, in order to connect the second portion 2132 to the ejector rod structure, before the second portion 2132 is connected to the first connecting member 2141, the second connecting member 2142 (in the fourth embodiment, the fourth connecting member 2144 replaces the second connecting member 2142), and the adjusting member 2170, the second portion 2132 passes through the through portion 2121b, and then the first connecting member 2141, the second connecting member 2142 (in the fourth embodiment, the fourth connecting member 2144 replaces the second connecting member 2142), and the adjusting member 2170 are connected to the second portion 2132, so that the second portion 2132 is prevented from being detached from the base 2120. It is also possible to connect the first connecting member 2141, the second connecting member 2142 (in the fourth embodiment, the fourth connecting member 2144 instead of the second connecting member 2142), and the regulating member 2170 to the second portion 2132, to pass the second portion 2132 through the ejector rod 2121 before the connecting portion 2121c is connected to the ejector rod 2121, and then to simultaneously dispose the second portion 2132 in the penetrating portion 2121b between the ejector portion 2121a and the connecting portion 2121c while the connecting portion 2121c is connected to the ejector portion 2121 a.
It should be noted that in each of the above embodiments, any two of the adjusting member 2170, the first connecting member 2141 and the second connecting member 2142 (in the fourth embodiment, the fourth connecting member 2144 replaces the second connecting member 2142) are restricted from passing through the through portion 2121b, so that the second portion 2132 is restricted from being detached from the base 2120, which does not require additional components, and therefore, the cost is low and the installation steps are fewer. But other ways than this may be used to achieve the second portion 2132 limited to being disengaged from the base 2120. For example, the second portion 2132 is in a woven belt structure, and a portion thereof is stitched to form a ring structure and is wrapped around the mandrel structure; or the second portion 2132 is in a webbing configuration, and a portion thereof is stacked in layers and sewn to form a thicker knot which is restrained from passing through the through portion 2121 b; it is also possible to provide exclusively two other parts (for example plastic stops) connected to the second portion 2132, both parts being located on either side of the ejector structure to be restricted from passing through the through-penetration 2121 b.
It should be noted that, the third embodiment has two second connectors 2142 located on the same side of the through portion 2121b, and the fourth embodiment has two fourth connectors 2144 located on the same side of the through portion 2121b, and when the second connectors 2142 or the fourth connectors 2144 are required to help limit the second portion 2132 from being detached from the base 2120, the present application does not limit all the second connectors 2142 or all the fourth connectors 2144 to pass through the through portion 2121b, and only any one of the second connectors 2142 or the fourth connectors 2144 needs to be limited to pass through the through portion 2121 b.
For example, in the fourth embodiment, there are two fourth connecting members 2144 located on the same side of the through portion 2121b and detachably connected to each other, one of the fourth connecting members 2144 in the fourth embodiment is flat and has a connecting hole, and the other fourth connecting member 2144 has a hook. The fourth embodiment is that one of the fourth connectors 2144 (i.e. the fourth connector 2144 with a hook) is restricted from passing through the through portion 2121b, and even if there is a flat fourth connector 2144 that can pass through the through portion 2121b, the second portion 2132 can be restricted from being detached from the base 2120 because the two fourth connectors 2144 are located on the same side of the through portion 2121 b.
The child safety seat 3001 and the connecting structure 3100 according to the present application are described in whole with reference to fig. 38A to 39B. In an embodiment of the present application, the connection structure 3100 is applied to the child safety seat 3001. However, it should be appreciated that in other embodiments, the connection structure 3100 may also be applied to other forms of carriers such as a basket, pet box, etc.
The child safety seat 3001 includes a seat body 3200 and two connection structures 3100. The seat body 3200 is a child seating portion that includes a backrest 3220, a seat portion 3230, and two side wings 3210. In the present application, for convenience of description, the front-rear direction of the seat body 3200 is referred to as a longitudinal direction, the up-down direction is referred to as a vertical direction, and the left-right direction is referred to as a lateral direction, however, it should be understood that these directions do not limit the arrangement of the child safety seat 3001 and the connection structure 3100, and the longitudinal direction, the lateral direction, and the vertical direction do not have to be perpendicular to each other.
The child safety seat 3001 may further include one or more cushion 3600 disposed on the seat body 3200, the cushion 3600 being disposed in a seating space of the child safety seat 3001, fig. 38A illustrates a cushion 3600 extending vertically and having a top higher than the seat body 3200, the cushion 3600 being supportable above the side wings 3210 and the rests 3220. The spacer 3600 is made of foam material (e.g., EPP material) and may be provided in other forms known in the art. The child safety seat 3001 may also include a seat cloth (not shown) covering the cushion 3600.
The connection structure 3100 has a cover 3130 that can be opened to expose the inside of the connection structure 3100 (see fig. 38A and 38B) or closed to shield the inside of the connection structure 3100 (see fig. 39A and 39B). The connection structure 3100 and the cover 3130 thereof will be described in detail below.
Fig. 40 shows a side view of the other side of the child safety seat 3001, wherein it can be seen that the other side is also provided with a connecting structure 3100. That is, the two connection structures 3100 may be symmetrically disposed at both sides of the child safety seat 3001. However, it is also possible to provide two connection structures 3100 asymmetrically or to provide only one connection structure 3100.
The overall structure of the child safety seat 3001 is described further with reference to fig. 41 to 42B.
The child safety seat 3001 of the present embodiment is a child carrier, and the child safety seat 3001 further has handles 3400 pivotally connected to both sides of the seat body 3200. The handle 3400 may be rotatable relative to the seat body 3200, e.g., about a lateral axis. Thus, the user can lift the seat body 3200 by the handle 3400. The child safety seat 3001 is configured to be removably coupled to a base (not shown) that is mountable within a vehicle (not shown), such that the child safety seat 3001 may be coupled to the base for use within the vehicle or may be detached from the base for use as a carrier alone. The child safety seat 3001 further includes two connection portions 3500 connected to the seat portion 3230, each connection portion 3500 may be disposed below the seat portion 3230. The two connection portions 3500 are spaced apart from each other and configured to be coupled with the base. For example, the connection portion 3500 can be coupled to the base by another engagement mechanism (not shown), and the present application is not limited to this type of engagement mechanism. Of course, in other embodiments, the child safety seat 3001 may be in other forms, not limited to child carrier forms.
The leaning portion 3220 is located at the rear of the seat portion 3230 and extends upward, and two side wings 3210 are located at both sides of the leaning portion 3220, respectively. The side wings 3210 serve to provide a more comfortable and safe seating environment for the child, and some of the devices of the child safety seat 3001 may be mounted to the side wings 3210. Both of the connection portions 3500 extend downward to facilitate downward mounting to a base (not shown).
Two connecting structures 3100 are respectively arranged on the two side wings 3210. More specifically, in the present embodiment, the connection structure 3100 may be disposed near a vertically middle position of the seat body 3200, but is not limited thereto, and the position of the connection structure 3100 may be flexibly adjusted according to the installation requirement of the strap 3300.
Referring to fig. 42A-42B, fig. 42B schematically illustrates a strap 3300 connected to the child safety seat 3001.
More specifically, the handle 3400 has two pivot portions 3410 connected to opposite sides of the seat body 3200, each pivot portion 3410 having a pivot center 3411. The handle 3400 is rotatable relative to the seat body 3200 about a pivot center 3411. The connecting structure 3100 is disposed on the side wings 3210 and proximate to the rear and above the seat body 3200 relative to the pivot center 3411. For example, in the present embodiment, each of the side wings 3210 has an outward extension 3211 (see fig. 38, 42A) extending outward and downward from an upper edge thereof, respectively, and the connection structure 3100 is located below the outward extension 3211. In addition, the connection structure 3100 may be located above the seat body 3200 with respect to the connection portion 3500. The seat cloth (not shown) of the child safety seat covers the cushion 3600 and can extend outwards to wrap the side surface of the cushion 3600, and the seat cloth can be clamped at the extension portion 3211 so that the seat cloth is connected to the seat body 3200. In addition, the connection structure 3100 is located forward of the front surface of the backrest 3220 of the seat body 3200 in the front-rear direction.
It will be appreciated that the base of a typical child safety seat may be secured to a vehicle such as a vehicle by a mount, so that in the event of a vehicle collision, the upper portion of the seat body may tilt, for example, rearward of the child safety seat (i.e. forward of the vehicle travel), thus presenting a safety hazard. According to the overall structure of the child safety seat 3001 of the present application, the connecting structure 3100 is positioned near the rear and above the seat body 3200. Accordingly, the strap 3300 connected to the child safety seat 3001 through the connection structure 3100 can apply a large pulling moment to the seat body 3200, advantageously preventing the seat body 3200 from tilting backward. On the other hand, since there is a certain distance between the connection structure 3100 and the upper edge of the seat body 3200, the structural strength of the seat body 3200 is not substantially affected. Furthermore, when the child safety seat 3001 is installed in a vehicle, the side wings 3210 of the child safety seat 3001 face the vehicle door. Since the connection structure 3100 is provided at the side wings 3210, a user can operate the connection structure 3100 at the door to connect or disconnect the tether 3300 to or from the seat body 3200, thus increasing the convenience of operation.
In the present application, the strap 3300 is connected to the upper portion of the side wings 3210 of the seat body 3200. However, the application is not limited thereto and the strap 3300 may be attached to other suitable locations of the seat body 3200, such as the bottom or back.
More specifically, strap 3300 includes an extension 3330 and two branches 3320. One end of each of the branch portions 3320 is connected to two connection structures 3100 provided on the seat body 3200, respectively, and the other end of each of the branch portions 3320 is combined with each other, for example, sewn together. The extension portions 3330 extend from the ends of the branch portions 3320 merging with each other, and the extension portions 3330 may be directly connected to a vehicle (not shown). For example, the extension portion 3330 may be sewn to the merging position of the two branch portions 3320, and one end of the extension portion 3330, which is not connected to the branch portion 3320, may be provided with a connector (not shown) to be connected to a seat (not shown) of the vehicle; the ends of the extension portion 3330 that are not connected to the two branch portions 3320 may be connected to other tethers (not shown) through which the extension portion 3330 is connected to a vehicle (not shown).
Each of the branch portions 3320 is connected to a corresponding connection structure 3100 through a second connector 3310, and a cover 3130 of the connection structure 3100 can cover the second connector 3310, which will be described in detail below. Accordingly, the inside of the connection structure 3100 and the second connection member 3310 are shielded by the cover 3130, providing a neat visual effect, while also avoiding unnecessary scratch caused by the exposed portions of the connection structure 3100 and the second connection member 3310 or avoiding the influence of foreign materials on the normal use of the connection structure 3100 after entering the inside of the connection structure 3100.
In the present application, the child safety seat 3001 is fixed to the vehicle in a back-to-back manner, i.e., with the back of the seat body 3200 facing the forward direction of the vehicle. The child safety seat 3001 is thus stably secured in the vehicle when the tether 3300 is connected to the seat of the vehicle.
Also, in the present embodiment, the tether 3300 extends in the longitudinal direction of the child safety seat 3001, and the second connector 3310 is connected to the connection structure 3100, for example, inserted into the connection structure 3100 in the transverse direction of the child safety seat 3001 (described in detail below). In the event of a vehicle crash, strap 3300 is subjected to a significant longitudinal pulling force. At this time, since the second connector 3310 is inserted into the connection structure 3100 in the lateral direction, the risk of being separated from the connection structure 3100 by the longitudinal tensile force can be reduced, and the connection stability between the connection structure 3100 and the second connector 3310 is increased, thereby improving the safety performance of the child safety seat 3001. It should be noted that the longitudinal extension of the strap 3300 along the child safety seat 3001 does not limit the strap 3300 to extend entirely in a straight form along the longitudinal direction, but rather means that the strap 3300 extends generally along the longitudinal direction in its overall configuration, and the pulling direction of the strap 3300 is generally in the longitudinal direction. For example, it will be appreciated that the strap 3300 is made of a flexible material, and that the portion of the strap 3300 that is adjacent to the connecting structure 3100 may be deformed somewhat by other structures that need to be bypassed around the seat body 3200 as it extends outwardly from the connecting structure 3100.
The connection structure 3100 and the strap 3300 according to the application are further described with reference to fig. 43.
The connection structure 3100 includes a receiving portion 3110, a first connection member 3120, a cover 3130, a guide 3140, and a reset member 3150. The strap 3300 includes the branch portion 3320 and the second connector 3310 connected to the branch portion 3320 as described above.
The receiving portion 3110 is mounted on the child safety seat 3001, for example, embedded in a side wing 3210 of the seat body 3200 (see fig. 38B). In this embodiment, the receiving portion 3110 is a separate component and is mounted to the child safety seat 3001 after assembly with the first connector 3120, the cover 3130, and the like. In other embodiments, the receptacle 3110 may also be integrally formed with the seat body 3200, e.g., as part of the side wings 3210 of the seat body 3200.
The first connection member 3120 is provided in the accommodating portion 3110 and is slidable in a sliding direction D1 so as to switch between the locked position and the unlocked position. The cover 3130 is provided on the accommodating portion 3110 and is convertible between an open position and a closed position with respect to the accommodating portion 3110. In the present embodiment, the cover 3130 is pivotally connected to the accommodating portion 3110, and thus pivots between an open position and a closed position. In other embodiments, the cover 3130 may be a part that is slidably movable or detachable with respect to the receiving portion 3110. The reset member 3150 is used to bias the first coupling member 3120 toward the locked position. The guide 3140 serves to slidingly couple the first coupling member 3120 to the receiving portion 3110 and guide a sliding direction D1 of the first coupling member 3120. The specific operation of the above-described components will be described in detail later.
A specific structure of the accommodating portion 3110 is described with reference to fig. 44.
The receiving portion 3110 includes an inner side 3113, four side walls, an extension wall 3112, a receiving cavity 3118, and a mounting portion 3117, wherein the receiving cavity 3118 has an opening 3119. For convenience of description, two of the four sidewalls extending in the longitudinal direction are referred to as a first sidewall 3111a and a second sidewall 3111b, respectively. In some embodiments, the receptacle 3110 may be a separate component mounted to the child safety seat 3001, such as a separate housing, mounted to the vehicle by means of bolts or welding, or the like. In other embodiments, the receptacle 3110 may be an integrally formed portion with the carrier, such as a recess formed in a side of the child safety seat 3001. In the present embodiment, as shown in fig. 44, the accommodating portion 3110 is a separate member mounted to the child safety seat 3001, and the mounting portion 3117 and the vehicle are fixed by a fastener (not shown) such as a bolt, thereby realizing mounting of the accommodating portion 3110 to the vehicle.
The inner side 3113 and the opening 3119 face each other. When the receiving portion 3110 is mounted to the seat body 3200 of the child safety seat 3001 or formed as part of the seat body 3200, the inner side 3113 is located inside the child safety seat 3001, with the opening 3119 facing outward of the child safety seat 3001. In the present embodiment, four side walls of the accommodating portion 3110 are each interconnected with the inner side surface 3113, wherein a first side wall 3111a and a second side wall 3111b extending in the longitudinal direction are opposed to each other, for example, are opposed to each other in the vertical direction, and the other two side walls are opposed to each other. Accordingly, the receiving portion 3110 is formed as a box-like structure having a substantially rectangular shape and one side opened.
It should be noted that, in this embodiment, the accommodating portion 3110 may be a separate component mounted to the child safety seat 3001, and may be formed with four sidewalls; but in other embodiments the number of side walls may be adjusted, and in other embodiments the separate component may itself have one, two or three side walls. Accordingly, when the receiving portion 3110 is mounted to the seat body 3220, the receiving portion 3110 having more sidewalls is formed together with the portion on the seat body 3200, or the receiving portion 3110 and the sidewalls thereof are integrally formed structures of the seat body 3200.
The extension wall 3112 extends from the inner side surface 3113 toward the opening 3119 to form an engagement space 3112a and a relief space 3112b. The engagement space 3112a defines an insertion direction D2 of the second link 3310, and the relief space 3112b provides a space for the first link 3120 to move to the locked position. When first coupling member 3120 is in the locked position, first coupling member 3120 is at least partially within relief space 3112b. More specifically, extension wall 3112 may be integrally formed with inner side 3113, such as by injection molding. The extension wall 3112 encloses an engagement space 3112a and a relief space 3112b. The engagement space 3112a is near the unlocked position of the first connection 3120, and the relief space 3112b is near the locked position of the first connection 3120. The engagement space 3112a may be open on a side toward the unlocked position to allow the first connection member 3120 to enter the engagement space 3112 (see fig. 49).

With continued reference to fig. 44, a receiving cavity 3118 is located between inner side 3113 and opening 3119 for receiving first attachment member 3120. The accommodating portion 3110 further includes a guide groove 3113a opened in the inner side surface 3113, and the guide groove 3113a corresponds to a position of the accommodating chamber 3118. The guide 3140 defines a sliding direction D1 of the first connection member 3120 (described in detail below) through the guide groove 3113a, however, it should be understood that in other embodiments, a guide structure such as a guide rail, a stopper, etc. may be provided in the receiving cavity 3118 to limit the sliding direction D1 of the first connection member 3120.
The specific structure of the first connection member 3120 is described with reference to fig. 46A and 46B.
The first connection member 3120 includes a hook portion 3121, an engagement portion 3122, a pressing portion 3123, an abutment portion 3124, a connection hole 3125, and a slope 3126. As previously described, first connection 3120 slides in sliding direction D1 between the locked position and the unlocked position, and for ease of understanding, the structure of first connection 3120 is described herein based on the direction of the locked position and the unlocked position.
The hook 3121 is proximate to the locked position and is configured to be connectable with the first connection member 3120. More specifically, the inside (i.e., right side in fig. 46A) and outside (i.e., left side in fig. 46A) of the hook portion 3121 are provided with an engagement portion 3122 and a slope 3126, respectively. The engagement portion 3122 is provided as a groove recessed into the hook portion 3121 toward the outside, more specifically an elongated groove extending in the vertical direction. The inclined surface 3126 is inclined toward the inside of the hook 3121 such that the hook 3121 forms a tip of a triangle. As will be described below in connection with the operation of the connection structure 3100, the snap-fit portions 3122 function to retain the second connection member 3310, and the inclined surfaces 3126 function to facilitate insertion of the second connection member 3310 into the connection structure 3100. In the present embodiment, the shapes of the engaging portion 3122 and the inclined surface 3126 are advantageous to provide a compact structure, however, in other embodiments, the engaging portion 3122 and the inclined surface 3126 may be provided in different forms as long as the second connection member 3310 can be maintained and the insertion of the second connection member 3310 into the connection structure 3100 is assisted.
The pressing portion 3123 is provided at a side of the first connection member 3120 adjacent to the opening 3119, and the pressing portion 3123 is close to the unlock position. The pressing portion 3123 is configured to be able to be pressed to move the first connection member 3120 to the unlocked position. More specifically, the pressing portion 3123 is provided as a recessed portion and has a wall extending laterally near the unlock position so that the user operates the pressing portion 3123. In this embodiment, the direction of deformation of the return member 3150 is in the longitudinal direction, and the user's finger is pressed against the wall in the longitudinal direction after entering the recess, thereby operating the first attachment member 3120 to move to the unlocked position. It will be appreciated that the pressing portion 3123 may also be provided in other suitable forms, such as a corrugated friction surface.
The connection hole 3125 is provided on the inner side 3113 (left side of fig. 46B) of the first connection member 3120. The guide 3140 is inserted into the connection hole 3125 to limit the sliding direction D1 of the first connection 3120 (see fig. 49). In this embodiment, the guide member 3140 is a screw, the tail portion of which is connected to the connection hole 3125, and the head portion of which is stopped at one side of the guide groove 3113a, so as to prevent the first connection member 3120 from being separated from the receiving cavity 3118.
Two abutting portions 3124 are provided on both sides of the pressing portion 3123, respectively, for defining a sliding range of the first connection member 3120 and providing an abutting surface of the reset member 3150, which will be described in detail below.
The specific structure of the branch portion 3320 of the strap 3300 and the second connector 3310 is described with reference to fig. 47.
The branch 3320 is, for example, a flexible braid, one end of which is connected to the second connector 3310. The second connecting member 3310 is in the form of a buckle, which is made of a sheet metal material, for example, and the second connecting member 3310 is provided with a clamping hole 3311. The snap holes 3311 are shaped to allow the hooks 3121 of the first connection member 3120 to pass through. In the present embodiment, the engagement hole 3311 is provided as an elongated hole, but in other embodiments, the engagement hole 3311 may be provided as another shape such as a square, a trapezoid, an ellipse, or the like to fit the hook 3121 of a different form.
In the present embodiment, the second connector 3310 is in the form of a buckle, however, in other embodiments, the second connector 3310 may be in the form of a hook, a mushroom head, a hanging ring, etc. The connection structure 3100 of the present application is applicable to various forms of the second connection 3310. In particular, the shape and connection relationship of the receiving portion 3110 and the cover 3130 are applicable to various forms of the second link 3310, and the form of the first link 3120 may be changed accordingly according to the form of the second link 3310.
Referring to fig. 48A and 48B, the relationship between the components of the connection structure 3100 is more clearly illustrated.
The first connection member 3120 is disposed in the accommodating cavity 3118 of the accommodating portion 3110 such that the pressing portion 3123 faces the outside of the accommodating portion 3110. The hook portion 3121 of the first connection member 3120 is inserted into the engagement space 3112a of the receiving portion 3110, and the reset member 3150 is disposed between the abutment portion 3124 of the first connection member 3120 and the side wall of the receiving portion 3110 to bias the first connection member 3120 to the locking position. The abutment portion 3124 provides an abutment position for the reset member 3150, and can limit the reset member 3150. The restoring member 3150 of the present embodiment is a spring, and the abutting portion 3124 is provided with a protruding portion 3124a (as shown in fig. 46B) at a position corresponding to the restoring member 3150, and the protruding portion 3124a can enter the spring to better position the spring. In the present embodiment, the first connection member 3120 extends in the vertical direction, and the two restoring members 3150 are vertically arranged at both sides of the pressing portion 3123. However, in other embodiments, more or fewer return members 3150 may be provided, for example, only one return member 3150 may be provided, which is located at the vertical center of the accommodating portion 3110, abutting against the vertically middle position of the first connection member 3120. In addition, in other embodiments, the number of the abutment portions 3124 may be adjusted, for example, only one abutment portion 3124 is engaged with one reset member 3150, or only one larger abutment portion 3124 is engaged with a plurality of reset members 3150 at the same time to limit the reset members 3150.
In addition, in the present embodiment, at least a portion of the extension wall 3112 is located on one side of the abutment 3124 along the sliding direction D1 of the first connection member 3120, and at least a portion of the extension wall 3112 is disposed opposite to the abutment 3124 along the sliding direction D1. When the first connection member 3120 is in the locked position, the abutment 3124 approaches or abuts the extension wall 3112. Thus, when first coupling member 3120 has a tendency to rotate about guide 3140, at least a portion of extension wall 3112 can abut against abutment 3124, thereby preventing first coupling member 3120 from rotating about guide 3140 within receiving cavity 3118. Of course, in other embodiments, the first connector 3120 may be restricted from rotating about the guide 3140 within the receiving cavity 3118 by providing the outer peripheral wall of the connection aperture 3125 as a non-circular wall (e.g., an elliptical or polygonal wall) and extending into the guide slot 3113a, with a stop-fit relationship of the outer peripheral wall of the connection aperture 3125 and the guide slot 3113 a.
The operation of the connection structure 3100 according to the present application is described with reference to fig. 49 to 53.
In the state shown in fig. 49, the first connector 3120 is in the locked position, the cover 3130 is in the open position, and the second connector 3310 is outside of the connection structure 3100. At this time, first coupling 3120 is biased to the locking position by reset member 3150. Since the cover 3130 is opened, the opening 3119 of the receiving portion 3110 is opened outward, and thus the second connector 3310 can be inserted into the receiving portion 3110 through the opening 3119.
From the state shown in fig. 49, the user moves the second connection member 3310 toward the inside of the receiving portion 3110 along the insertion direction D2 (i.e., the lateral direction of the present embodiment), so that the second connection member 3310 enters into the engagement space 3112a and abuts against the inclined surface 3126 of the first connection member 3120, to the state shown in fig. 50.
From the state shown in fig. 50, the user moves the second connector 3310 further toward the inside of the accommodating portion 3110 in the insertion direction D2. When the second link 3310 enters the connection structure 3100, the second link 3310 abuts against the inclined surface 3126 so that the first link 3120 is temporarily moved away from the locking position toward the unlocking position against the pressure of the reset member 3150 by the pushing of the second link 3310, i.e., the state shown in fig. 51 is reached.
Starting from the state shown in fig. 51, since the first connection member 3120 is located at or near the unlock position, it allows the second connection member 3310 to continue to move toward the inside of the receiving portion 3110 in the insertion direction D2. When the second link 3310 enters the receiving portion 3110, the engagement hole 3311 of the second link 3310 corresponds to the position of the hook 3121, so that the first link 3120 returns to the locking position by the reset member 3150 while the hook 3121 passes through the engagement hole 3311 to the state shown in fig. 52.
In the state shown in fig. 52, the second connection member 3310 is held in the receiving portion 3110 by the first connection member 3120. At this time, if the second link 3310 receives a tensile force of the branch portion 3320 of the tie 3300, the second link 3310 moves outwardly relative to the receiving portion 3110 (i.e., moves reversely in the insertion direction D2), so that the second link 3310 is caught in the engaging portion 3122 of the receiving portion 3110, as shown in fig. 53. Therefore, the second connection member 3310 cannot leave the first connection member 3120 but is stably held in the receiving portion 3110 by the first connection member 3120, improving the safety performance of the connection structure 3100.
When the second connector 3310 enters the accommodating portion 3110, the user may pivot the cover 3130 to the closed position, so that the connecting structure 3100 reaches the state shown in fig. 54. When the cover 3130 is in the closed position, the cover 3130 shields the second connector 3310 in the connection structure 3100. The branch portion 3320 of the tie 3300 extends to the outside of the connecting structure 3100 through a gap between the free end 3132 of the cover 3130 and the receiving portion 3110. The gap between the free end 3132 of the cover 3130 and the receiving portion 3110 is drawn in an exaggerated manner in fig. 54. In practice, since the branch portion 3320 is composed of a flexible fabric, the gap may be so small as to be difficult to observe from the outside of the connection structure 3100. In this way, the cover 3130 shields the inner parts of the connection structure 3100 and the second connector 3310, so that the connection structure 3100 has a neat appearance. It will be appreciated that the cover 3130 in the closed position has some restriction on movement of the strap 3300 such that the strap 3300 extends closer to the outside of the seat body 3200.
The operation of locking the second connector 3310 to the connection structure 3100 is described above. When the user desires to disengage the second connector 3310 from the connection structure 3100, the above-described operations may be performed in reverse order. Specifically, the user first opens the cover 3130, then presses the second connector 3310 toward the inside of the accommodating portion 3110 (i.e., along the insertion direction D2) to disengage the second connector 3310 from the engaging portion 3122 of the first connector 3120, then moves the first connector 3120 toward the unlocking position by operating the pressing portion 3123 to disengage the hook portion 3121 from the engaging hole 3311, and finally removes the second connector 3310 from the accommodating portion 3110. It should be appreciated that after removing the second connector 3310, the user may close the cover 3130 to restore the neat appearance of the connection structure 3100 or to avoid debris from entering the interior of the connection structure 3100.
In summary, the present application provides a child safety seat having a connection structure that can be opened and closed to connect a harness, and an insertion direction of the harness is different from a pulling direction of the harness. The present application also provides a connection structure having a simple and compact structure, capable of stably locking the second connection member, and having a closable cover to provide a neat appearance.
