Detailed ways

In order to describe the technical content, structural features, achieved objects and effects of the present invention in detail, the following detailed description is given in conjunction with the embodiments and the accompanying drawings.

As shown in FIGS. 1-7 , the automatic pop-up side impact protection device 300 provided by the present invention is suitable for a child safety seat. The automatic pop-up side impact protection device 300 is provided at the backrest side wing 200 of the child safety seat 100 to provide side impact protection for a child sitting in the child safety seat 100 during a side impact. The automatic pop-up side impact protection device 300 of the present invention includes a force-bearing mechanism 310 connected to the backrest side wing 200 of the child safety seat 100 . The side impact protection device 300 further includes an automatic control part 330 , and the automatic control part 330 is subjected to force with the use of the child safety seat 100 to drive the force bearing mechanism 310 to move relative to the backing side wing 200 to be in a pop-up position.

The automatic pop-up side impact protection device provided by the present invention is arranged at the backrest side wing 200 of the child safety seat 100, and its effect is that when the child safety seat 100 is in use, it can automatically keep the pop-up state to provide anti-collision protection . In some preferred embodiments, the child safety seat 100 can also be conveniently folded to save space when the child safety seat 100 is not in use. It can be understood that the "use of the child safety seat 100" referred to in the present invention includes but is not limited to when the child safety seat 100 is connected to the base, when a child rides the child safety seat 100, or the child safety seat 100 The handle part needs to be pivoted to a specific position when in use, and the use of the child safety seat 100 will inevitably be accompanied by a certain state change, and the automatic control part 330 will be driven by the state change due to the state change. The automatic control unit 330 drives the force-bearing mechanism 310 to move relative to the backrest side wings 200 , so that the force-bearing mechanism 310 is in the ejected position when the child safety seat 100 is in use.

1-7, the first embodiment of the automatic pop-up side impact protection device of the present invention will be described in detail.

Exemplarily, in this embodiment, the force-bearing mechanism 310 is pivotally connected to the back-rest side wing 200 , and the force-bearing mechanism 310 has a pop-up position and a retracted position relative to the back-back side wing 200 . The following will take the bearing mechanism 310 pivotally connected to the backrest flank 200 as an example for detailed description, but it is not limited to this. Those skilled in the art can be inspired by the automatic ejection side impact protection device provided by the present invention. The force mechanism slides, extends, and moves as a whole to switch between the pop-up position and the retracted position. Preferably, the force bearing mechanism 310 always has an action tendency to pivot to the eject position.

As shown in FIGS. 3-7 , the automatic pop-up side impact protection device 300 further includes a limit mechanism 320 connected to the backrest side wing 200 , and the limit mechanism 320 includes a limit member 321 and a drive member 322 . When the force bearing mechanism 310 When the backrest side wings 200 are pivoted to the folded position, the limiting member 321 limits the force-bearing mechanism 310 to keep the force-bearing mechanism 310 in the folded position. When the driving member 322 drives the limiting member 321 to limit the position When the force-bearing mechanism 310 is released from the limit by the component 321, the force-bearing mechanism 310 can be pivoted to the pop-up position relative to the backrest side wings 200; the automatic control part 330 is used to control the driving component 322 to keep the child safety seat 100 in use. The driving member 322 drives the limiting member 321 to release the state of limiting the force-bearing mechanism 310 .

As shown in FIGS. 1-7 , the automatic pop-up side impact protection device provided by the present invention mainly includes a force bearing mechanism 310 , a limit mechanism 320 , and an automatic control unit 330 . The load-bearing mechanism 310 is symmetrically pivoted to the back-rest side wing 200 , the force-bearing mechanism 310 can pivot relative to the back-back side wing 200 , and when the force-bearing mechanism 310 pivots to the eject position relative to the back-back side wing 200 , the force-bearing mechanism The 310 can provide side impact protection during the use of the child safety seat 100; when the force bearing mechanism 310 is pivoted to the folded position relative to the backrest side wings 200, space can be saved. It can be understood that the force-bearing mechanism 310 always has an action tendency to pivot to the pop-up state, which can be realized by the torsion spring 313 disposed at the pivotal connection between the force-bearing mechanism 310 and the backing side wing 200 as shown in FIG. 3 . The limiting mechanism 320 corresponds to the force bearing mechanism 310 and is disposed in the backrest side wing 200 , and the limiting mechanism 320 is provided for limiting the force bearing mechanism 310 pivoted to the folded state. The automatic control part 330 is arranged at a position where the child safety seat 100 is convenient to control, and through the automatic control part 300, when the child safety seat 100 is in use, the limiting mechanism 320 does not limit the force-bearing mechanism 310, so that the force-bearing mechanism 310 is not limited. The mechanism 310 is in the ejected position during use of the child safety seat 100 .

It can be understood that the automatic control part 330 can always keep the force-receiving state during the use of the child safety seat 100, and the driving limiting mechanism 320 is kept away from the limiting effect on the force-bearing mechanism 310. When the child safety seat 100 is in use, the state of the child safety seat 100 is inevitably changed and the force is triggered, and the limiting mechanism 320 is driven to disengage from the limiting effect on the force-bearing mechanism 310. At this time, the force-bearing mechanism 310 relies on the torsion spring 313 shown in FIG. 3 or Other structures make the force bearing mechanism 310 have an action tendency to remain in the pop-up position. Specifically, in this embodiment, as shown in FIG. 1 , the automatic control part 330 includes a control part 331 arranged at the seat of the child safety seat 100 , and can be specifically arranged at the seat part of the child safety seat 100 . When the child safety seat 100 is used, the control member 331 is driven by the infant's own weight, and when the child safety seat 100 is used, the control member 331 is triggered by force and drives the driving member 322, so that the limiting mechanism 320 is disengaged from the bearing force The mechanism 310 has a limiting effect, and the control member 331 is constantly subjected to pressing force during the process of the infant sitting on the child safety seat 100, so as to control the limiting mechanism 320 to maintain the state of being separated from the limiting state of the force-bearing mechanism 310, and ride on the child safety seat 100. Infants and toddlers in the child safety seat 100 are under side impact protection, which improves riding safety. Of course, the control member 331 can also be disposed at the backrest, headrest and other positions, as long as the child safety seat 100 is kept in use, the control member 331 is triggered by force and drives the limiting mechanism 320 to disengage from the bearing force The mechanism 310 only has a limiting effect.

As shown in FIG. 1 to FIG. 3 , the force-bearing mechanism 310 is generally arranged laterally in the pop-up state, and the force-bearing mechanism 310 is pivotally connected to the backrest side wings 200 of the child safety seat 100 near the rear end of the backrest, and the support The front end side of the force mechanism 310 remote from the backrest can pivot relative to the pivot axis. As shown in FIG. 3 and FIG. 4 , a torsion spring 313 is provided at the pivot shaft of the force bearing mechanism 310 and the backrest wing 200 , and the torsion spring 313 makes the force bearing mechanism 310 always have a tendency to pivot to a pop-up state. 5-7, the force-bearing mechanism 310 includes a side impact protection block 311 and an engaging structure 312 pivotally connected to the side impact protection block 311. The engaging structure 312 is arranged on the outer side of the side impact protection block 311 in the ejection direction, The side impact protection block 311 is provided with an escape hole 311 a for the engaging structure 312 to extend into the inner side in the ejection direction of the side impact protection block 311 to be limited by the limiting member 321 . Specifically, in this embodiment, as shown in FIGS. 5-7 , the engaging structure 312 includes an engaging block 312a disposed on the outer side of the side impact protection block 311 in the ejecting direction, and one end of the engaging block 312a is slidably connected to the side impact protection block 311. The protection block 311; the side impact protection block 311 is provided with an avoidance hole 311a, a screw 312b passes through the avoidance hole 311a and is fixedly connected to the engaging block 312a, and the nut at one end of the screw 312b away from the engaging block 312a is used for connecting with the limiting mechanism 320 can be detachably connected, so as to limit the position of the force bearing mechanism 310 .

Referring again to FIGS. 4-7 , the limiting mechanism 320 includes a limiting member 321 , a driving member 322 , and a pushing member 323 . In this embodiment, the limiting member 321 and the driving member 322 are pivotally connected at different positions of the backrest side wing 200 , respectively. One end of the driving member 322 is pivotally connected to the backrest wing 200, and the other end of the driving member 322 can be pivoted to drive the limiting member 321; the driving end of the automatic control part 330 is shown in FIG. 5-FIG. 7 The linking member 332 is connected to one side of the driving member 322 and is located at a position approximately in the middle of the driving member 322 , so as to drive the driving member 322 to pivot relative to the backing side wing 200 . The limiting member 321 is disposed outside the free end of the driving member 322, the main body of the limiting member 321 is circular, and is pivotally connected to the backrest side wing 200 through the center of the circle of the limiting member 321; the limiting member 321 faces the bearing One side of the mechanism 310 is provided with a hook portion 321a for engaging the force-bearing mechanism 310. When the force-bearing mechanism 310 is rotated to the retracted position, the screw 312b is close to the hook portion 321a, and the hook portion 321a is snapped to the screw 312b the nut, so as to limit the force-bearing mechanism 310 to be in the limit state.

Further, as shown in FIGS. 4 to 7 , the pushing member 323 is inserted into the driving member 322 ; one end of the pushing member 323 extends out of the driving member 322 and abuts against the limiting member 321 , and the pushing member 323 faces the driving member 322 . One end of the limiting member 321 protrudes to form a pushing portion 323a, and is driven by the driving member 322 to drive the limiting member 321 to pivot away from the force-bearing mechanism 310 through the pushing portion 323a, so that the locking member 321 is locked. The hook portion 321a is separated from the screw 312b of the force bearing mechanism 310 . Furthermore, the limiting member 321 is also provided with a protrusion corresponding to the pushing portion 323a.

It can be understood that the limiting member 321 , the driving member 322 , and the pushing member 323 all have a tendency to move in the direction of the clamping force-bearing mechanism 310 , and only when the automatic control unit 330 drives the driving member 322 , Only the limiting member 321 , the driving member 322 , and the pushing member 323 overcome their own tendency to move and maintain the state of releasing the force bearing mechanism 310 . The unidirectional movement trend of the limiting member 321 , the driving member 322 , and the pushing member 323 can be realized by an elastic member. Specifically, torsion springs 321c and 322a may be provided at the positions where the limiting member 321 and the driving member 322 are pivotally connected to the backrest side wings 200, respectively, as shown in FIG. The pushing member 323 moves outward to push the retaining spring 323b of the limiting member 321 , as shown in FIGS. 5-7 .

In the automatic pop-up side impact protection device provided by the present invention, the distance between the limiting mechanism 320 and the automatic control part 330 for driving the limiting mechanism 320 is relatively long. In order to allow the position of the automatic control part 330 to be set more flexibly, the automatic control part 330 further includes a linking member 332, and the linking member 332 may be a rigid wire. When one end of the linking member 332 disposed on the automatic control part 330 receives force, it can quickly transmit the received force to the limiting mechanism 320 to realize the linkage between the two.

1-7, the use process of the child safety seat 100 with the first embodiment of the automatic pop-up side impact protection device of the present invention will be described in detail:

When no infant sits on the child safety seat 100, the control member 331 is not subjected to external force. At this time, under the action of the torsion springs 321c, 322a, and the retaining spring 323b, the limiting member 321, the driving member 322, and the pushing member 323 maintain the state that the hook portion 321a can be engaged with the screw 312b. At this time, the force-bearing mechanism 310 is in the folded position, as shown in Figures 1-3;

When the infant sits on the child safety seat 100, the control member 331 is driven by the infant's own weight, and the control member 331 is constantly subjected to pressing force and drives the driving member 322, so that the limiting member 321, the driving member 322, and the pushing member 323 Overcoming the elastic force of the torsion springs 321c, 322a, and the retaining spring 323b, the limiting member 321 pivots to a state where the hook portion 321a cannot be clamped with the screw 312b, and the force bearing mechanism 310 is relatively backed against the side wings under the elastic force of the torsion spring 313 200 pivot to eject position;

It can be understood that the force-bearing mechanism 310 in the ejected position drives the force-bearing mechanism 310 to overcome the elastic force of the torsion spring 313 and pivot to the retracted position under the action of an external force. The limiting member 321, the driving member 322, and the pushing member 323 are in a state where the screw 312b cannot be clamped; but if the control member 331 is not pressed, under the elastic force of the torsion springs 321c, 322a, and the retaining spring 323b, The limiting member 321 , the driving member 322 , and the pushing member 323 act to make the hook portion 321 a engage with the screw 312 b so that the force-bearing mechanism 310 is in the retracted position.

When the limiter 321 engages with the force-bearing mechanism 310 to keep the force-bearing mechanism 310 in the retracted position, and the driving element 322 drives the limiter 321 to disengage the limiter 321 from the engagement with the force-bearing mechanism 310 , the force-bearing mechanism 310 is pivoted to an ejected position relative to the back against side flap 200 . According to the automatic pop-up side impact protection device provided by the present invention, when the child safety seat 100 is in use, the force-bearing mechanism 310 is not limited by the limiting mechanism 320, and automatically pivots to the pop-up position, while in the child safety seat 100 When the 100 is not in use, the limiting mechanism 320 is in a state where the force-bearing mechanism 310 can be limited under the action of the torsion springs 321c, 322a, and the circlip 323b, and the force-bearing mechanism 310 is driven by an external force to pivot to the retracted position. , the limiting mechanism 320 limits the force-bearing mechanism 310 so that the force-bearing mechanism 310 can be kept in the retracted position. The automatic pop-up side impact protection device provided by the present invention can automatically pop up at the same time during the use of the child safety seat 100 to provide sufficient back-to-side impact protection, that is, to save operation steps and prevent child caregivers from forgetting to put the side impact protection The block is turned to the pop-up state, and when the child safety seat 100 is not in use, the force-bearing mechanism 310 can be easily pushed to pivot relative to the back side wing 200 and is limited to the retracted position by the limiting mechanism 320 to reduce the retracted volume. .

In this embodiment, the automatic control unit 330 includes a control member 331 , a link member 332 and a reset member 333 . The control member 331 is slidably disposed on the backrest portion 110 of the child safety seat 100 and is connected to one end of the link member 332 , and the control member 331 partially protrudes from the front of the backrest portion 110 , and the reset member 333 interferes with the control member 333 . Between the control member 331 and the backrest portion 110 , the reset member 333 always tends to make the control member 331 protrude from the backrest portion 110 . In this way, when the child sits in the child safety seat 100, the child's back will abut on the control member 331 to exert a pressing force to make it slide toward the inside of the backrest portion 110 (see FIG. 16), thereby pulling the connecting The moving member 332 is then used to pull the limiting mechanism 320 through the linking member 332 to release the lock. In addition, during the process of sliding and retracting the control member 331 into the backrest portion 110 , the reset member 333 is compressed and deformed. When the control member 331 loses the pressing force, the reset member 333 restores its deformation and drives the control member 331 to protrude out of the backrest. part 110 (see Figure 15).

It can be understood that the automatic control part 330 is not limited to the above arrangement, and can also be provided in other parts of the child safety seat 100 , and FIGS. 17-18 show another alternative embodiment of the automatic control part 330 .

14, 17-18, in this embodiment, the automatic control part 330 also includes a control part 331, a linking part 332 and a reset part 333, which is different from the above embodiments in that the control part 331 It is slidably arranged in the seat portion 120 of the child safety seat 100, and is matched with the five-direction safety belt 130 provided on the child safety seat 100, because when the five-way safety belt 130 is used, it will inevitably be pulled It is adjusted so that the movement of the control member 331 is driven by the adjustment of the five-way seat belt 130 .

The cooperation of other parts also does not affect the realization of this scheme.

As shown in Figures 19-26, it is the second embodiment of the automatic pop-up side impact protection device of the present invention.

The functions of the components and the functions to be implemented are the same as those of the first embodiment, but their specific structures are different. specific:

As shown in FIGS. 20-22 , in the second embodiment of the automatic pop-up side impact protection device of the present invention, the automatic control part includes a control member 331 ′ disposed at the bottom of the child safety seat 100 , and the two ends are respectively connected to the control member 331 ′. 331' and the linking piece 332' of the limiting mechanism 320'. The control member 331 ′ is disposed protruding from the bottom of the child safety seat 100 , and when the child safety seat 100 is connected to the base 400 , the control member 331 ′ protruding from the bottom of the child safety seat 100 is constantly affected by the base 400 . Pressing to drive the driving member 322' through the linking member 332', so that the force bearing mechanism 310' automatically pops up, so as to ensure that the infant sitting in the child safety seat 100 is not hurt, and the riding safety is improved. Specifically, the control member 331 ′ is pivotally connected to the bottom of the child safety seat 100 via the pivot shaft 331 a ′, and the side of the control member 331 ′ protruding from the bottom of the seat 100 is provided with a driving surface 331 b ′. When connected to the base 400 , the base 400 pivots relative to the child safety seat 100 against the control member 331 ′ via the driving surface 331 b ′, and then drives the driving member 322 ′ through the linking member 332 ′.

For the limiting mechanism 320 ′, as shown in FIGS. 23 to 26 : the limiting member 321 ′ is movably disposed on the outer side of one end of the force-bearing mechanism 310 ′ away from the pivot, and the limiting member 321 ′ is connected to the force-bearing mechanism 310 . 'Limiting surfaces 321a', 311a' are respectively provided on the sides facing each other, and the limiting member 321' always has the ability to move toward the force-bearing mechanism 310' to limit the force-bearing mechanism 310' from being in the position of the force-bearing mechanism 310' through the limiting surfaces 321a', 311a'. The action trend of the retracted position, and the driving member 322' drives the limiting member 321' to move away from the force-bearing mechanism 310' to release the limitation of the force-bearing mechanism 310'.

Specifically, in this embodiment, as shown in FIGS. 23 to 26 , the lower end side of the force bearing mechanism 310 ′ is pivotally connected to the backrest flank 200 , and the upper side of the force bearing mechanism 310 ′ can be opposite to the back with the lower end side as the center The side wing 200 is pivoted to the pop-up position or the retracted position; the limiting member 321 ′ is arranged on the upper side of the force-bearing mechanism 310 ′, and is located outside the end of the force-bearing mechanism 310 ′ away from the pivot, and the limiting mechanism 320 ′ can be It moves up and down relative to the force-bearing mechanism 310' to be close to or away from the force-bearing mechanism 310'; the side of the limiting member 321' facing the force-bearing mechanism 310' is correspondingly provided with a limiting surface, and when the limiting mechanism 320' moves downwards When approaching the force-bearing mechanism 310 ′, the force-bearing mechanism 310 ′ is restricted by the limiting surface to maintain the retracted position, and when the limiting mechanism 320 ′ moves upward away from the force-bearing mechanism 310 ′, the force-bearing mechanism 310 ′ is separated from the position of the limiting surface. The restraint can automatically pivot to the eject position. It can be understood that the limiting member 321' should always have an action tendency to move downwards close to the force-bearing mechanism 310' and limit the force-bearing mechanism 310' to be in the folded position.

Preferably, as shown in FIGS. 24-26 , the limiting surfaces 321a ′ and 311a ′ are inclined from the position near the backrest side wing 200 to the direction away from the backrest side wing 200 , that is, the highest point of the inclined surface is close to the backrest side wing 200 . , the downward pressing force of the limiting member 321 ′ generates a component force that restricts the ejection of the force bearing mechanism 310 ′ through the inclined surface.

The pivot point is located at the middle position of the driving member 322'; one end of the driving member 322' away from the force-bearing mechanism 310' is connected to the driving end of the automatic control part 330', that is, the linkage shown in Figs. 24-26 One end of the component 332', the limiting component 321' is fixedly connected with a locking pin 321b', and the other end of the driving component 322' close to the force-bearing mechanism 310' is provided with a locking groove 322b' corresponding to the locking pin 321b' to drive the The member 322' is driven by the link member 332' to drive the limiting member 321' to move away from the force bearing mechanism 310' via the locking groove 322b' and the locking pin 321b'. It can be understood that the driving member 322' always has an action tendency to drive the limiting member 321' to move in the direction of the force bearing mechanism 310'.

In the second embodiment of the automatic pop-up side impact protection device of the present invention, when the child safety seat 100 is installed at the base 400, the limiting mechanism 320' can be released from the force bearing mechanism 310'. When the child safety seat 100' is removed from the base 400 or is not connected to the base 400, the limiting mechanism 320' remains capable of engaging with the force-bearing mechanism 310'.

Referring to FIGS. 27-33 again, the third embodiment of the automatic pop-up side impact protection device of the present invention will be described in detail.

In the third embodiment of the automatic pop-up side impact protection device of the present invention, the same as the first and second embodiments, the automatic pop-up side impact protection device 300" also includes a force bearing mechanism 310" and a limit mechanism 320". And the automatic control part 330 ″, the structure of this automatic control part 330 ″ is preferably the same as that in the above-mentioned second embodiment, and will not repeat them, and the functions of other components and the functions to be realized are the same as the first embodiment, But its specific structure is different. Specifically:

In this embodiment, the limiting mechanism 320 ″ is pivotally connected to the backrest side wing 200 , and the limiting mechanism 320 ″ has an arc-shaped structure centered on the backrest side wing 200 ; the bearing mechanism 310 ″ is also pivotally connected to The back-to-side wing 200, and the force-bearing mechanism 310", the limit mechanism 320", and the back-to-side wing 200 are pivotally connected to the same pivot axis. The force-bearing mechanism 310" includes the limit mechanism 320" and the back-to-side wing that can be perpendicular to the limit mechanism 320". The engaging structure 315" moves in the direction of the pivot shaft of 200; the arc-shaped outer edge side of the limiting mechanism 320" is provided with a limit for the engaging structure 315" to keep the force-bearing mechanism 310" in the retracted position. The first limiting position 324" of the position, and the second limiting position 325" for limiting the engaging structure 316" to keep the force bearing mechanism 310" in the open position; the automatic control part drives the limiting mechanism 320" to pivot Rotate so that the engaging structure is switched between the first limiting position 324" and the second limiting position 325".

Preferably, the engaging structure 315" always has an action tendency to move in the direction of the limiting mechanism 320" and the pivot axis of the back-to-side wing 200. Specifically, it can be realized by the elastic member 315a" as shown in FIG. 30-FIG. 33. 31-33, at least part of the engaging structure 315" exposes the force-bearing mechanism 310", so that the engaging structure 315" can be operated by an external force. Further, as shown in FIG. 31-FIG. 33, the limiting mechanism 320' is further provided with a limiting guide surface 326" between the first limiting position 324" and the second limiting position 325", and the first limiting position 324" Compared with the second limiting position 325 ″, it is farther away from the limiting mechanism 320 ″ and the pivot shaft of the backrest side wing 200 , so the engaging structure 315 ″ is easier to disengage from the first limiting position 324 ″ and pass through the limiting position. The guide surface 326" comes to the second limiting position 325", and the engaging structure 315" limited by the second limiting position 325" is not easily disengaged.

Driven by the elastic member 315a ″, the engaging structure 315 ″ always has an action tendency to move in the direction of the limiting mechanism 320 ″ and the pivot axis of the back-to-side wing 200 , and the force-bearing mechanism 310 ″ pivots relative to the back-to-side wing 200 When the engaging structure 315 ″ is turned to face the first limiting position 324 ″, the engaging structure 315 ″ moves and engages in the direction of the limiting mechanism 320 ″ and the pivot shaft of the back-to-side wing 200 under the driving of the elastic member 315 a ″. The first limited position 324" keeps the force bearing mechanism 310" in the folded position; when the automatic control part 330" drives the limit mechanism 320" to pivot, driven by the external force, with the movement of the limit mechanism 320" After pivoting, the engaging structure 315" leaves the first limiting position 324" and comes to the second limiting position 325" via the limiting guide surface 326", so that the force bearing mechanism 310" is reliably limited and is in the ejecting position, At this time, if there is no external force to drive the exposed part of the engaging structure 315" of the force bearing mechanism 310", the engaging structure 315" cannot escape from the second limiting position 325" by itself.

Please refer to Fig. 34-Fig. 37 again, which is an alternative embodiment of the automatic control part:

In this embodiment, the force-bearing mechanism can be selected from the force-bearing mechanism 310 of the first embodiment of the present invention or the force-bearing mechanism 310' of the second embodiment of the present invention. Of course, the force-bearing mechanism 310" of the third embodiment can also be selected. The limiting mechanism adopts the limiting mechanism 320 of the first embodiment of the present invention or the limiting mechanism 320 ′ of the second embodiment corresponding to the force-bearing mechanism, and of course the limiting mechanism 320 ″ of the third embodiment can also be selected. Specifically, the selection of the force bearing mechanism 310' and the limiting mechanism 320' in the second embodiment is taken as an example. The function of each component and the function to be realized are the same as those of the first embodiment and the second embodiment, and the difference is only in the structure of the automatic control part 330'''. Specifically:

The driving member 320' at the other end of the linking member 332'''. It can be understood that the end button 332a''' can also be connected to the end of the handle portion 500 extending into the pivot portion 600, so that the handle portion 500 is relatively pivotally connected During the pivoting process of the part 600, the end button 332a''' can also be driven.

In the third embodiment of the automatic pop-up side impact protection device of the present invention, the operating member 700 and the handle portion 500 are driven by an external force to control whether the limiting mechanism 320 ″' is engaged with the force-bearing mechanism 310 ′. It can be understood that the structural The relative positions of the end button 332a''' and the operating member 700 are designed so that when the handle portion 500 is pivoted to the middle of the seat 100 in the use state, the limiting mechanism 320"' maintains and releases the force-bearing mechanism 310', and when the handle portion 500 is pivoted to the middle portion When the part 500 is pivoted to one side of the seat 100 , the limiting mechanism 320 ″' remains capable of engaging with the force bearing mechanism 310 ′.

14, 38-43, which are other alternative embodiments of the automatic control part of the automatic pop-up side impact protection device of the present invention. The force-bearing mechanism and the limiting mechanism of this embodiment can be the structures in any of the above-mentioned embodiments, and will not be repeated here.

When the five-direction safety belt 130 is used, the cross belt 132 and the waist belt 133 must be directly pulled, or the cross belt 132 and the waist belt 133 will be pulled indirectly through the webbing 131 a under the reverse locking buckle 131 .

Then, the limiting mechanism 320 is driven to release the lock by the linking member 332"", so that the force-bearing mechanism 310 is pivoted to the ejecting position. During the above process, the reset member 333' is compressed and deformed.

In the process of use, since the five-direction safety belt 130 is always in the locked state, the force-bearing mechanism 310 can always be kept in the pop-up position. Only after the five-direction safety belt 130 is released, the reset member 333 ′ can recover its deformation and drive. The cross-strap fixing member 132a is reset, so that the force-bearing mechanism 310 can be pivoted to the collapsed position.
