Description

Child seat for attachment to a motor vehicle seat

DESCRIPTION

The invention relates to a child seat for attachment to a motor vehicle seat, and to a method for adjusting side impact protection of a child seat. A child seat is already known from EP 2 275 303 A1, in which side impact protection can be transferred from a rest position to a functional position. In principle for the same purpose, DE 10 2015 214 910 A1 also discloses side elements that can be transferred from a rest position to a functional position, whereby in the functional position the side element there, referred to as the side protection block, is locked by means of a button referred to as a protective component, with this button being pressed in order to be able to fold in the side element or to be able to release a lock in the unfolded state. In the folded position of the protective component, the button is recessed within the protective component. The state-of-the-art solutions are considered to be in need of improvement from a safety perspective, with the particular risk that Side impact protection when using the child seat is not correctly in a functional position is considered high.

It is the object of the invention to propose a side impact protection for a child seat which has adjustable side impact protection in a simple, safe and yet cost-effective manner. In particular, it is also an object of the invention to propose side impact protection that is easy to handle. Furthermore, it is the object of the invention to propose a corresponding method.

This task is solved in particular by the features of claim 1.

In particular, the object is achieved by a child seat for attachment to a motor vehicle seat, the child seat having at least one side surface and a side impact protection (wherein the side impact protection can be formed at least partially by the side surface, or can be formed completely in addition to the side surface), whereby the side impact protection comprises: a side impact protection base, and a side element which is movable (in particular rotatable and/or displaceable) relative to the side impact protection base and which is between a rest position (rest position), in particular within a predetermined width of the child seat, and one, in particular outside the predetermined width, functional position (and vice versa) can be transferred, wherein the side element in the functional position projects beyond the side surface in the lateral direction, wherein the side element in the rest position does not project beyond the side surface or projects less far beyond than in the functional position, whereby (for manual and / or automatic actuation) position transfer means are provided to enable a transfer from the rest position to the functional position, the position transfer means preferably being configured in such a way that in a first step a lateral projection over the side surface can be at least substantially fixed and in a second step the side element or at least one displacement section of the side element, the weight of which is preferably at least 15% by weight (more preferably at least 25% by weight or at least 50% by weight or at least 90% by weight, possibly 100% by weight) of the total weight of the side element and/or which is at least partially visible in the rest position (seen from the outside) (partially preferably means that at least 0.5 cm ² , preferably at least 1.0 cm ² , possibly at least 2.5 cm ² or at least 5.0 cm ² of a surface is visible), is displaceable, in particular (translationally) displaceable , preferably in such a way that the side element comes to rest at least in sections (possibly directly, in particular touching) over (on) a section of the side surface adjacent to the side element.

The length of the displacement section preferably corresponds to at least 30%, preferably at least 50%, if necessary at least 70% or at least 90%, if necessary at least 100% of the length of the entire side element. Alternatively or additionally, the width of the displacement section can correspond to at least 30%, preferably at least 50%, if necessary at least 70% or at least 90%, if necessary at least 100% of the width of the entire side element. Alternatively or additionally, the height of the displacement section can correspond to at least 30%, preferably at least 50%, if necessary at least 70% or at least 90%, if necessary at least 100% of the height of the entire side element. Alternatively or additionally, a (maximum) diameter (understood as the distance between that pair of points of the displacement section or correspondingly referred to element/structure with the greatest distance from one another) of the displacement section can be at least 30%, preferably at least 50%, possibly at least 70% or correspond to at least 90%, if necessary at least 100% of the (maximum) diameter of the entire side element.

One idea of the invention is to divide the kinematics of the side element into two steps during the transfer from the rest position to the functional position. In particular, in a first step, the side element is at least essentially brought into its end position insofar as it extends or projects in a lateral direction (i.e. in particular outwards or in a direction that is horizontal in use, perpendicular to the direction in which the child is viewing or in a horizontal direction direction perpendicular to the direction of travel when the child seat is properly positioned). In the second step, a displacement in particular takes place in such a way that the side element comes to lie (in sections) above the side surface, in particular directly. The statement “over” is intended in particular to imply that a projection of the side element overlaps with a section of the side surface adjacent to the side element (if the projection takes place onto this adjacent section). A direction of the projection preferably corresponds to a surface normal to the adjacent section. The The overlap area preferably has an area of at least 0.5 cm ² , preferably at least 1 cm ² , possibly at least 2.5 cm ² and/or at most 40 cm ² or at most 25 cm ² or at most 10 cm ² , possibly at most 5 cm ² on.

Among the position transfer means (or

Position transfer enabling means) are to be understood in particular as meaning those structures of the child seat that contribute to enabling the position transfer. The position transfer means can, for example, have at least one sliding surface and/or at least one stop and/or at least one bearing, e.g. B. plain bearings. The position transfer means can widely include at least one drive, e.g. B. include at least one spring. The position transfer means can be configured to enable transfer by manual and/or automatic operation.

The side surface is in particular a surface directed outwards (at least essentially away from the child or a space intended to accommodate the child).

A distance of the adjacent section of the side surface from the side element in the functional position (in a direction parallel to the surface normal to the adjacent section of the side surface) can be at most 1 cm, preferably at most 0.5 cm, even more preferably at most 2 mm, even more preferably at most 1 mm. If necessary, the distance can be equal to zero or, if necessary, the side element and the adjacent section of the side surface can touch each other at least at points in the functional position.

According to the invention, the side element itself (or at least significant components thereof, for example in contrast to the displacement of the comparatively small and therefore less robust button of DE 10 2015 214 910 Al) is displaced in an advantageous manner in order to block the side element in the functional position in a side impact situation (by passing it through the adjacent section of the side surface is prevented from shifting towards the child).

Preferably, the side element or its displacement section is movable during the second step at least substantially transversely to the lateral direction and/or (at least in sections) at least substantially along the adjacent (outward-facing) side surface. A substantially transverse movement is to be understood in particular as meaning that a direction of movement forms an angle of 90° ± 30°, preferably 90° ± 10°, even more preferably 90° ± 5° with respect to the lateral direction (as defined above). . A movement substantially along the adjacent side surface is to be understood in particular as a movement that has a direction that is at least substantially parallel to the adjacent side surface (in particular a difference in the direction of at most 30°, preferably at most 10°, even more preferably is at most 5°). If the movement is a rotation, the direction of the movement of at least one point (possibly all points) of a surface of the side element that is opposite the adjacent section of the side surface should be taken into account. Such a point will follow a circular path during pure rotation. In general, the movement in the second step can be (purely) translational and/or (purely) rotational. In this respect, the respective above condition should apply to at least 30%, possibly at least 80% or at least 95% of a total length of the (possibly curved or straight) movement path.

The rest position (rest position) is preferably a stowed position in which the side element offers no or only little (compared to the functional position) protection in the event of a side impact. In the functional position (functional position or use position), the side impact protection function of the side element is significantly increased (compared to the rest position). The rest position is also referred to below as the first position, the functional position as the second position. In particular, the early connection of the child seat (and a child in the child seat) to the dynamics of the accident can be seen as protection in the event of a side impact. According to the embodiment, a child seat with at least one side surface and a side impact protection is proposed, the side impact protection comprising: a (side impact protection) base, and a side element movable relative to the base, the side element relative to the base (reversible) between a first position and a second Position can be transferred, wherein the side element in the second position projects beyond the side surface in the lateral direction, wherein the side element in the first position does not project beyond the side surface or projects less far beyond than in the second position, the transfer between the first position and the second position being a first Step and a second step, wherein in the first step the lateral projection is adjusted, and wherein in the second step the side element (or its upper displacement section) is moved at least substantially transversely to the lateral direction and / or at least substantially along the side surface.

The child seat can have a seat area and a backrest. It also advantageously has a headrest. Depending on the design, the child seat can also include a seat base. Additional equipment such as restraint devices for holding back a child (e.g. harness and/or impact shield) can be provided alternatively or additionally.

The seating area preferably forms a seat surface for supporting the buttocks (possibly also parts of the thighs) of a child and can have first side surfaces. The seating area can alternatively or additionally comprise armrests which can extend at least substantially above the seat surface, with lap belt guides for guiding the lap belt of a vehicle belt being able to be provided - in particular between the armrests and the seat surface.

The child seat can include fastening means for fastening to a vehicle seat, in particular Isofix connectors and/or LATCH connectors and/or comparable means. The fastening means can be provided at a rear and/or lower end of the seating area. In versions with a seat base, the fastening means can alternatively or additionally be provided at a rear and/or lower end of the seat base. The backrest can be formed integrally with the seating area and rigidly connected to it, or it can be movable relative to the seating area - in particular adjustable in terms of inclination. Furthermore, the backrest forms a back contact surface for contacting or supporting the back of a child, and preferably comprises second side surfaces (of which at least one side surface is preferably combined with the side impact protection explained above and/or below). The backrest can have side bolsters which can be formed integrally with the section of the backrest forming the back contact surface and rigidly connected to it, or which can be movable relative to the back contact surface - in particular adjustable in terms of width. The second side surfaces can be formed, in particular completely or partially, by sections of the side cheeks.

The optional headrest can be formed integrally with the backrest and rigidly connected to it, or it can be movable relative to the backrest - in particular adjustable with regard to an inclination and / or a distance of the headrest from the seating area. Furthermore, the headrest can form a head contact surface to support the head of a child and form third side surfaces. It can have side wings, which can be formed integrally with the section of the headrest forming the head contact surface and rigidly connected to it, or which can be movable relative to the head contact surface - in particular adjustable in terms of width. The third side surfaces can be formed, in particular completely or partially, by sections of the side wings. Shoulder belt guides can be provided on the headrest, in particular on the side wings and preferably at their lower end.

In versions with a seat base, the seat base can form fourth side surfaces.

Seat and back contact area as well as, if applicable, head contact area and the inside of armrests and/or side bolsters and/or side wings define a reception area (reception space) for a child.

Each of the first to fourth side surfaces can (optionally) be combined with the side impact protection explained above and/or below or form the side surface according to claim 1. In the context of the present application, the term child seat should be understood to include all types of child seats, for example baby seats or so-called booster seats (and the like). Furthermore, directional information (such as front, back, right, left, top, bottom, inside, outside, side, etc.) should be understood to reflect the perspective of a child sitting normally in a child seat and looking straight ahead. Insofar as reference is made to children and their body parts, the reference can equally be used for dummies, in particular dummies from Humanetics (according to the version that is or was current at the time of registration or priority), for example dummies from Q- Series, apply. In particular, depending on the seat size, a suitable dummy can be selected from these dummies, for example a Q0, Ql, Ql, 5, Q3, Q6 and/or Q10, where the number after the Q corresponds to the approximate age of a child of comparable height and weight.

The child seat in particular has a side impact protection, which is described in detail below. In particular, the side impact protection has a side impact protection base and a side element that is movable relative to the side impact protection base, wherein it is preferably provided that the side element can be reversibly transferred between a first position (stowed position and/or retracted position) and a second position (use position and/or extended position). In the second position, the side element projects beyond a side surface (or an adjacent section thereof) of the child seat, while in the first position the side element does not project beyond the side surface or projects beyond it less than in the second position. The side surface is preferably a second side surface, but depending on the embodiment, reference can also be made to a first, third and/or fourth side surface.

Preferably, in its second position, the side element is the part of the child seat that projects furthest to the side.

The transfer between the first position and the second position of the side element preferably comprises a first step in which the lateral projection is adjusted (at least substantially), and a second step in which the side element is adjusted (at least substantially) transversely to the lateral direction and/or is moved along the side surface. The transfer from the first position to the second position preferably initially comprises the first step and then the second step. The transfer from the second position to the first position preferably first includes the second step and then the first step.

Preferably, the side impact protection is attached, in particular fastened, to the side of the child seat or to the side surface of the child seat (which in particular should not exclude the possibility that the side impact protection is at least partially further inward than adjacent sections of the side surface).

It can be provided that the side impact base or a base outer surface is formed completely or partially in one piece, in particular integrally, with the side surface. The side surface and side impact base can merge into one another.

The side impact base may include a frame that may form an opening. The frame can be a section of the side surface that frames the opening (the optional function of which is described in more detail below). The side impact base may further include portions that completely or partially close the opening inwardly. The opening can, for example, be designed completely or partially as a blind hole or as a through hole in the side surface and/or in the base. According to embodiments, the side impact base may include, for example, portions that span the opening such as a bridge or footbridge and/or portions that protrude into the opening such as a platform. The side impact base is preferably configured to cooperate with the side member to provide one or more side impact protection functions.

The side member may have a side member outer surface that is visible (ie, not obscured by other parts of the child seat) in the first position and that can, for example, completely or partially close the opening of the side impact base in the first position. The side element outer surface can be directed at least substantially away from the child in the first and/or second position. Furthermore, the side element can have an inner surface that is (substantially) not in the first position is visible, for example because it is hidden by other parts of the child seat. The inner surface can be designed at least in sections as an edge surface, and it can be provided that the inner surface is visible (preferably only partially) in the second position. The inner surface can be directed at least substantially away from the child in the first and/or second position (possibly without taking the edge surface into account).

The page element can be made up of several sub-elements. For example, it may include an outer part that forms the outer surface. It may also include an inner part that allows interaction with the base, which will be explained in more detail below.

Preferably, the side element is rotatable (in particular exclusively) about an axis, in particular a fixed or movable one, during the first step. Alternatively or additionally, the side element (or its displacement section) is (in particular exclusively) displaceable or translationally movable during the second step. Alternative or additional types of movement are explained below.

The side element is preferably designed as a folding element (flap) which can be folded about a (fixed or movable) axis, in particular in order to carry out the first step of transferring between the first position and the second position. The rotation can also be superimposed by a translation (or vice versa).

According to the embodiment, the first step can be carried out by a (pure) translation. Alternatively or additionally, the second step can be carried out by (pure) rotation.

Both steps can be carried out by a (pure) translation, whereby the corresponding displacement axes or displacement directions can differ (for example by at least 10° or at least 45° or at least 80°).

Both steps can be performed by (pure) rotation, whereby the corresponding rotation axes can differ (for example by at least 10° or at least 45° or at least 80°). The side element can comprise a proximal portion close to the axis, and the side element can comprise a distal portion that is further away from the axis than the proximal portion and, in the second position, further outward (further away from the receiving area) than the axis. The axis can be physically formed, for example as a separate component. However, the axis can also be a fictitious axis, e.g. a film hinge.

The second step is preferably carried out as a translation of the page element. The side element can slide on the side impact protection base and/or on the side surface of the child seat. Alternatively, the second step can be carried out as a rotation. Preferably, one of the first and second steps includes a rotation and the other of the first and second steps includes a translation.

As already shown, in a particularly preferred variant, the first step (in particular exclusively) comprises a folding, while the second step (in particular exclusively) comprises a translation. In another preferred embodiment, the first step (in particular exclusively) comprises a translation, while the second step (in particular exclusively) comprises a rotation.

To form the folding mechanism, as described above, an axis can be provided, which can be designed completely or partially as a physical axis. The side element can include a side element axle holder in which the axle can be mounted. The side impact protection base can include (particularly in a rear section) a base axle mount in which the axle can be mounted. The side element axle receptacle and/or the base axle receptacle can be designed to allow translation of the side element relative to the side impact protection base in at least one, preferably exactly one, folding position of the side element relative to the side impact protection base. For this purpose, the side element axle mount and/or the base axle mount can have at least one, preferably at least two, elongated hole(s) in which the axle can slide. The orientation of the elongated hole(s) can be selected such that sliding of the axis in the (respective) elongated hole is only possible if the side element is in a position between an intermediate position, in particular the one mentioned below (if starting from the first Position the first step was taken, or if the second step was taken starting from the second position) and the second position is located.

The second step may include a translational movement of the axle in one of the side element axle mount and the base axle mount. The second step can also involve, in particular translational, movement of the entire side element (or at least significant parts of it, e.g. at least 15% by weight or at least 50% by weight or at least 90% by weight thereof) relative to the side impact protection -Base include. With regard to the proximal section, the movement can be guided by the axle and axle mount. The distal end can slide on the side impact protection base, in particular on a front portion of the side element. For this purpose, the side impact protection base can have a sliding section which can guide the side element (at least in sections between the intermediate position and the second position). The side impact protection base may have a base holding portion, which may be provided in particular adjacent to the sliding portion and/or at the front portion of the side impact protection base. The side element can have a side element holding section, in particular at the distal end, wherein the side element holding section can be supported on the base holding section in the second position.

Preferably, the first step and/or the second step (possibly after lifting a respective lock) takes place automatically (or automatically), preferably supported by at least one or exactly one spring (or another drive), or at least two or exactly two spring(s), more preferably by at least one first spring to support the second step and/or at least one second spring to support the first step.

The side impact protection can comprise a first spring which drives the side element to be completely transferred to the second position (in particular from an intermediate position in which, according to the first step, protrusion over the side surface is already at least substantially set). The first spring can be, for example, a helical spring (eg a compression spring or a tension spring), a leg spring, a leaf spring or another suitable elastic element. The first spring can have two ends, with which it is attached to the side element on the one hand on the other hand, can be supported on another element of the child seat, in particular on the side impact protection base. For this purpose, a first side element spring attachment can be provided on the side element, and a first base spring attachment can be provided on the side impact protection base. The first side element spring fastening and/or the first base spring fastening can be designed as a projection, in particular at least approximately cylindrical, onto which the first spring can be attached. However, depending on the type of spring used, other embodiments are also possible, such as, in particular, groove-like recesses into which the respective end of the spring can be inserted. The embodiments described below in connection with the second spring are also possible.

The task of the first side element spring fastening or first base spring fastening is, in particular, to enable stable support of the first spring on the respective element in order to enable safe and error-free execution of the second step.

The side impact protection can comprise a second spring, which preferably drives the side element to be transferred to the intermediate position in which, according to the first step, protruding beyond the side surface is at least substantially set. Alternatively, but not preferably, the second spring can be designed to completely transfer the side element (in particular from an intermediate position in which protrusion over the side surface is at least essentially set according to the first step) into the first position. The second spring can be, for example, a helical spring (eg a compression spring or a tension spring), a leg spring, a leaf spring or another suitable elastic element. The second spring can have two ends with which it can be supported on the one hand on the side element and on the other hand on another element of the child seat, in particular on the base. For this purpose, a second side element spring attachment can be provided on the side element, and a second base spring attachment can be provided on the side impact protection base. The second side element spring attachment and/or the second base spring attachment can be designed to enable engagement or gripping of the second spring (e.g. hooking a hook-like end of the second spring into a hole or gripping a projection with a ring-like one End). However, depending on the type of spring used, other embodiments are also possible, in particular those described in connection with the first spring.

The task of the second side element spring fastening or second base spring fastening is, in particular, to enable stable support of the second spring on the respective element in order to enable safe and error-free execution of the first step.

Preferably, the side impact protection is designed such that the first and second springs completely transfer the side element from the first position to the second position. The second spring may drive the side member to perform the first step from the first position to adjust the side member to extend further beyond the outer surface than in the first position. The first spring may drive the side member to perform the second step to prevent a laterally acting, inwardly directed force from moving the side member into the first position against the action of the second spring.

The side impact protection can be designed such that the transfer from the first position to the second position (after a first initiation of the transfer, as explained in more detail below) is completely spring-driven, in particular by the first and second springs. The transfer from the second position to the first position occurs during the second step, preferably against the force of the first spring. During the first step, the transfer from the second position to the first position can take place against the force of the second spring.

According to the embodiment, the first spring and the second spring can be formed by a single combined spring. It can also be provided that only a second spring is provided. Each first spring, each second spring and each combined spring can (precisely) comprise one or more spring elements. However, there should preferably be (exactly) a first spring and (exactly) a second spring, each of which is implemented by exactly one spring element.

Preferably, the functional position (in relation to a transfer to the rest position, in particular in relation to folding) can be locked. Alternatively or in addition, the rest position can be locked (compared to being transferred to the functional position, in particular compared to being folded out). A locking means in particular that the side element moves (at least not without overcoming a force threshold of, for example, at least 0.5 N or at least 1 N or at least 10 N or at least 100 N) in the direction of the other position of the rest and functional position , in particular can move in any direction before a corresponding locking mechanism is released.

The side member may include a side member stop and the side impact protection base may include a base stop. The side member stop and base stop may be configured to cooperate to limit outward movement of the side member. In particular, after the first step, the side element can rest against the base stop with the side element stop during the transfer from the first position to the second position, and/or in the second position. In the first position, the side element stop may be spaced from the base stop.

In the first position, further inward displacement of the side element, in particular further folding of the side element, can be at least substantially prevented (possibly except for a slight remaining displaceability, see below) by the side element abutting the side impact protection base at least in sections.

The side impact protection may further comprise a holding device to hold the side element in the first position. This is particularly useful if - as shown above - a second spring is provided, which is biased in the first position of the side element in order to drive the side element to (further) project beyond the side surface in the lateral direction. The holding device may include a side element holding device and a base holding device. In this case, one of the side element holding device and the base holding device preferably engages with the other of the side element holding device and the base holding device in order to hold the side element in the first position. To initiate the transfer of the side element from the first position to the second position, the engagement can be released. According to the embodiment, for example, one of the side element holding device and the base holding device can comprise a latch, and that others of the side element holding device and base holding device include a latch receptacle.

It can be provided that the holding device is designed in such a way that the transfer of the side element from the first position to the second position is initiated by pressing inwards (in the direction of the receiving space or child). For this purpose, it can be provided that the side element can be moved slightly further inwards beyond the first position in order to release the side element from the first position and/or to release the engagement of the holding device.

Specifically, the side element holding device can comprise a projection, in particular comprising a head. The base holding device may include a guide portion which is supported by structures of the side impact protection base, e.g. B. is provided by structures of the bridge, or which can be provided as an independent component in a holding device receptacle. A movable section can be provided in the guide section, which can in particular include at least or exactly one or at least or exactly two arms, which are preferably designed to be resilient. The at least or exactly two arms can be designed to define, without external force, an opening into which the side element holding device, in particular the head, can be inserted. The movable section can assume an extended position relative to the guide section in which no force acts on the arms, and the movable section can assume a retracted position relative to the guide section in which the guide section compresses the arms (against the spring force) to form the side member - Holding device, especially the head, to hold. To change between the extended position and the retracted position, a mechanism known per se can be used (for example like a ballpoint pen).

Preferably, the side element and the side impact protection base comprise a pair of mutually complementary engagement structures, in particular at least one projection-recess pair, which inhibits a transfer from the functional position to the rest position, preferably such that the inhibition is achieved by a force of less than or equal to 50 N, more preferably less than or equal to 10 N and/or greater than or equal to 0.1 N, preferably greater than or equal to 0.5 N, possibly greater than or equal to 1 N can be overcome.

The side impact protection base may include a base retention engagement (e.g., a recess), particularly at the base retention portion. The side member may have a side member retaining engagement (e.g., a projection), particularly on the side member retaining portion. One of the base retainer and the side member retainer may engage the other of the base retainer and the side member retainer in the second position of the side member to inhibit movement of the side member (away from the second position).

It can be provided that the transfer of the side element from the second position to the first position is initiated by pressing or pushing the side element (and/or rotating the side element), in particular in the opposite direction to the direction in which the first spring drives the side element. It can be provided that the side element is (slightly) moved away from the side surface in order to release the base holding engagement and the side element holding engagement from one another. It can further be provided that the transfer of the side element from the second position to the first position is completed by pressing the side element, in particular the distal section of the side element, inwards.

Preferably, the side element can be folded backwards during the first step (in particular such that, when viewed from above, a side element attached to the right-hand side of the child seat folds clockwise and a side element attached to the left-hand side of the child seat folds anti-clockwise). Alternatively or additionally, the side element or its displacement section can be displaced forwards during the second step.

The side impact protection is preferably designed and attached to the child seat in such a way that when the side element is transferred from the first position to the second position, the movement of the side element in the second step does not take place backwards (but preferably forwards). When moving backwards, there is a particular risk that the side element in the second step will hit the backrest of the vehicle and/or something close to it Object placed on the backrest and may not reach the second position. In addition, the side element may be difficult to access for release from the second position because the backrest of the vehicle and/or the object is in the way.

The side impact protection is preferably at least partially, possibly completely, in a back section of the child seat, in particular at the rear of a back contact surface, and/or above a seat section (possibly above a level of an uppermost point of the seat section) of the child seat and/or on an outside of a seat shell of the child seat.

Preferably, the side element is made of an at least substantially rigid material. This can in particular be hard plastic such as PE and/or PP or the like.

In the following description, the same reference numbers are used for identical and identically functioning parts.

Figure 1 shows a child seat 10 according to the invention. The child seat 10 optionally comprises a headrest 40 with a head contact surface 41, a seating area 20 with a seat area 21, and a backrest 30 with a back contact area 31. The seat area 20 can have fastening means 22 for attaching the child seat 10 include a vehicle seat. The seating area 20 can include first side surfaces 24 on its outside. Side cheeks 32 are also formed on the backrest 30, which have second side surfaces 33 on the outside of the child seat 10 (the side facing away from the child in the child seat). A side impact protection 100 is formed on (or on) the second side surfaces 33 of the side cheeks 32. Side wings 42 can be formed on the headrest 40, which have third side surfaces 43 on the outside of the child seat 10.

Figure 2 shows a side view of a section of the second side surface 33 of the side cheek 32 of a child seat 10 according to the invention. The side cheek 32 includes the side impact protection 100, which includes, among other things, the side element 120 and the side element outer surface 121. As can be seen in FIG. 1 and in particular in FIG . The side impact protection 100 is in the first position here.

Figure 3 shows a side view of a section of the second side surface 33 of the side cheek 32 of a child seat 10 according to the invention. The side impact protection 100 with the side element 120 and the side element outer surface 121 is in the second position in this figure. The side impact protection 100 is no longer embedded in the second side surface 33 of the side cheek 32, but protrudes at least partially beyond it. In contrast to the first position, it can now be seen that the edge surface 122 projects beyond the second side surface 33 or protrudes or protrudes from the second side surface 33. The side element outer surface 121 goes into this Position is not flush with the adjacent sections of the second side surface 33 of the side cheek 32.

Figure 4 shows the side impact protection 100 according to the invention as an exploded view. Figure 5 shows a sectional view. The side impact protection 100 includes the side element 120, which can be arranged to be pivotally movable to the side impact protection base 140 by an axis 110. The side impact protection base 140 is part of the side impact protection 100 and serves as a particularly fixed (e.g. fixed or attached) counterpart to the movable side element 120. The side impact protection base 140 can be at least partially attached within the second side surface 33. The side impact protection base 140 may have an opening 142 between its rear portion 149 and its front portion 150 in which the side member 120 may be at least partially embedded.

The side element 120 preferably has a side element axle receptacle 126 through which the axle 110 can be guided. The side impact protection also has a second spring 112 which forces the side element 120 into a projecting position, i.e. pushes it to the left (away from the child), and a first spring 111 which pushes the side element 120 into the second position forward (away from the child) along the second side surface 33. In addition, a base holding device 144 can be provided which is attached to the side impact protection base 140, which locks the side element 110 in the first position and which can be unlocked to initiate the transfer to the second position.

The base holding device 144 may include or consist of a guide portion 145a in which a movable portion 145b is guided, and arms 145c. Furthermore, an optional frame 153 (which can be part of the side impact protection base 140) is provided, which surrounds the side element 120 in the first position and can serve as a contact surface for the side element 120 in the second position. A side element stop 123 is provided on the side element 120, which limits the side element 120 in the second position before further unfolding, caused by the second spring 112. 5 shows the side impact protection 100 in the first position in section, embedded in the second side surface 33 of the side cheek 32. The axis 110 is firmly connected to the side impact protection base 140 on the base axle receptacle 146 and runs through a proximal section 129 of the side element 110 the (guide-shaped, in particular groove-shaped) side element axle holder 126, and thus supports the side element 120 in a pivotable manner relative to the base. The side element axle holder 126 is designed in particular as a guide, in particular as a groove and/or as an elongated hole. In the first position, the axle 110 is located at a distal end of the side member axle receptacle 126, which end is closer to the distal portion 130 of the side member 120.

The second spring 112 may be connected to the side impact protection base 140 at one end by a second base spring mount 148 and to the side member 120 at the other end by a second side member spring mount 128. The second spring 112 can be compressed in the first position and thus press against the side element 120 from the inside. The head 125 of the side member 120 can engage the arms 145c of the base holding device 144, whereby the side member 120 is locked against unfolding by the force of the second spring 112, so that it remains in the embedded first position.

The edge surface 122 of the side element 120 rests at least on a distal section 130 on the sliding section 156 of the side impact protection base 140 and is at least partially guided by this (when transitioning to the second position).

The first spring III may be connected to the side impact protection base 140 at one end through a first base spring mount 147 and to the side member 120 at the other end through a first side member spring mount 147. The first spring 111 may be stretched in the first position, pulling on a proximal end of the side member 120 (on the first side member spring attachment 147), thereby pressing a distal portion of the edge surface 122 against the sliding portion 156.

By applying force (in the direction of the child) to the proximal section 129 of the side element 120, the movable section 145b of the base Holding section 144 is pushed along the guide section 145a (in the direction of the child) and the arms 145c are brought into the open position.

Figure 6 shows the side impact protection 100 in a position (in particular an unstable intermediate position) between the first and second positions in section, after the transfer by the second spring 112 (to the left) and before the transfer by the first spring 111 (towards the front). In this position, the axle 110 is still located at a distal end of the side member axle receptacle 126. The arms 145c of the base holding device 144 are opened, whereby the head 125 of the side member 120 is no longer held by the arms 145c and thus the locking is counteracted an opening of the side element 120 is solved. The force of the second spring 112 presses the side element 120 into an outstanding (open, unfolded) position. The side element stop 123 rests on the base stop 143, whereby the opening of the side element 120 is limited by the second spring 112. The interaction between the side element stop 123 and the base stop 143 blocks further movement of the side element 120 to the left (away from the child). The distal edge surface 122 of the side element 120 is no longer guided by the sliding section 156 and protrudes beyond the sliding section 156, and in particular lies outside the sliding section 156. The movement of the side element 120 forward along the second side surface is no longer restricted in this position , whereby the first spring 111 is released.

Figure 7 shows the side impact protection 100 in the second position in section, after being transferred by the second spring 112 (to the left) and after being transferred by the first spring 111 (towards the front). In this position, the axle 110 is located at a proximal end of the side member axle mount 126, which end is closer to the proximal portion 130 of the side member 120. The force of the second spring 112 continues to press the side element 120 into the (open, unfolded) overhanging position. The side element stop 123 continues to rest (slightly pushed forward) on the base stop 143, which further prevents the side element 120 from being opened further by the second spring 112. By releasing the first spring 111, the side member 120 was pushed forward (to the second position) on the first side member spring mount 147. Further forward movement of the side element 120 is prevented by the abutment of the axle 110 at a proximal end of the side element axle receptacle 126. In the second position, the distal section of the edge surface 122 now lies in front of the sliding section 156 and thus prevents unwanted movement of the side element 120 due to possible forces (e.g. crash scenario) from the left (towards the child) back into the embedded first position. In this position, the side element retaining engagement 132 engages in the base retaining section 151, and the base retaining engagement 152 engages in the side element retaining section 131, whereby the side element 120 is locked from slipping back (towards the rear) in the event of possible force from the front.

Figure 8 shows the side element 120 from behind. Figure 10 shows the frame 153.

An alternative embodiment is shown in detail in Figures 10 to 13. The side element is displaced (translationally) in the first step and rotated in the second step. For this purpose, the side element can have at least one recess 120a, e.g. a groove, possibly a circumferential groove.

At this point it should be noted that all parts described above are viewed on their own and in any combination, especially the details shown in the drawings, are claimed to be essential to the invention. Modifications to this are familiar to those skilled in the art.

It should also be noted that the aim is to provide the broadest possible scope of protection. In this respect, the invention defined in the claims can also be specified by features that are described with further features (without these further features necessarily being included). It is explicitly pointed out that round brackets and the term “in particular” are intended to emphasize the optionality of features in the respective context, which does not mean, conversely, that without such identification a feature is to be viewed as mandatory in the corresponding context.
