Description

Detailed Description of the Invention

[0001] [explanation] The present invention relates to a shock absorber for a child car seat for installation on a vehicle seat, and to a corresponding child accommodation device, in particular a child car seat, and to a method for adjusting the child car seat or the shock absorber.

[0002] Child seats with shock absorbers are known, for example, from DE 10 2012 100 707 A1. Such shock absorbers are intended to keep a child seated in the seat in particular in the event of an accident or sudden braking. Such shock absorbers can be fastened to the child seat itself. In DE 10 2012 100 707 A1, fastening of the shock absorbers is achieved by means of corresponding belt sections.

[0003] Furthermore, solutions are known, for example from DE 10 2022 100 184 A1, in which essentially rigid fastening structures are present for fastening the crash absorber to both sides of the child car seat, sections of which are displaceable in order to adjust the crash absorber (with respect to the size of the child).

[0004] Overall, it is believed that the prior art solutions are in need of improvement with regard to the adjustment of the shock absorber, particularly with regard to the size of the child.

[0005] The object of the invention is to propose a shock absorber for a child car seat (for attachment to a vehicle seat) that can be adjusted relatively precisely (with respect to the size of the child) and at the same time in a simple manner. It is also an object of the invention to propose a corresponding device for accommodating a child, in particular a child car seat, and a corresponding method for adjusting the child car seat or the shock absorber.

[0006] This object is achieved in particular by the features of claim 1.

[0007] In particular, the object is to provide a shock absorber for a child car seat (for attachment to a car seat), - a restraining part (for restraining a child, in particular in the event of an accident or braking); - a first connecting part and a second connecting part, each of which is movable, in particular displaceable, at least piecewise (and if necessary only piecewise) from at least a first position to at least a second position relative to the restraining part; an adjustment mechanism for adjusting the respective positions of the first and second connecting parts, the adjustment mechanism comprising an operative connection that connects the first and second connecting parts to one another and such that the adjustment of one of the first and second connecting parts results in a corresponding adjustment of the other of the first and second connecting parts (and preferably vice versa, whereby the adjustment of the other of the first and second connecting parts results in a corresponding adjustment of the one of the first and second connecting parts); Equipped with This is achieved according to a first independent aspect by a shock absorber for a child car seat.

[0008] One idea behind the first embodiment is to enable, by means of the operative connection, a functional coupling, in particular synchronization, between the adjustment of the first connecting part and the adjustment of the second connecting part, in particular in such a way that a load on the first connecting part via the operative connection (e.g. due to lateral loading of the restraining part adjacent to the first connecting part) also causes the second connecting part to be loaded accordingly, thereby achieving in particular a uniform adjustment of the restraining part (e.g. to adapt the restraining part or the shock absorber as a whole to the size of the child).

[0009] In principle, as can be observed, for example with regard to DE 10 2022 100 184 A1, in prior art solutions with rigid connection structures, the connection structures cannot always be adjusted (completely) independently of one another. However, due to the lack of an active connection there, a unilateral load on the shock absorber (e.g. a unilateral pull on the shock absorber, which widens the space between the shock absorber and the body of the child car seat) leads to tilting, which ultimately makes the overall adjustment more difficult or does not allow adjustment in the case of a unilateral load.

[0010] Under operative connection, in particular, a connection (between a first connecting part and a second connecting part) may be understood which transmits a positional change from one of the two connecting parts to the other of the two connecting parts, in particular in such a way that the other connecting part is also (correspondingly) adjusted. The operative connection is preferably additional to the restraining part (or its body) and is partially or completely movable (in particular displaceable and / or rotatable, for example partially displaceable and partially rotatable) relative to the restraining part (or its body). In particular, the operative connection should not be considered to already exist (as the case may be) even if two connecting structures are each connected to the restraining part (or its body) and thus connected to each other via the restraining part (or its body).

[0011] According to a second aspect (independent and preferably combinable with the first aspect), a shock absorber for a child car seat is proposed, said shock absorber comprising: a restraining portion having a central portion and right and left end portions; - a first connecting part and a second connecting part, each of which is movable, in particular displaceable, at least piecewise from at least a first position to at least a second position relative to the restraining part; - a fixing mechanism configured to selectively, in particular completely, fix or not fix the first connecting part and the second connecting part relative to the restraining part, the fixing mechanism in particular comprising a form-fitting fixing device, preferably a latch and an engagement part, which fixing device is provided at least partially on the central part of the restraining part, in particular in the center of the restraining part.

[0012] One idea of ​​the second embodiment is to provide a fixing device on the central part of the restraining part, which allows reliable fixing (immobilization) of the first connecting part or the second connecting part to be performed in a simple manner, which improves usability and therefore safety.

[0013] In principle, the restraining portion can have a central portion as well as right and left end portions.

[0014] The centre of the restraining part is preferably understood to mean an area of ​​the restraining part which is in each case at least 20%, preferably at least 30% or at least 40% of the left and right extension of the restraining part, away from the two outermost points (left and right) of the restraining part. When "left" or "right" is mentioned here and below, particular reference is made to the position that the shock absorber takes when (correctly) mounted on the child seat.

[0015] According to a third aspect (preferably combinable with the first and / or second aspect), a shock absorber for a child car seat (for mounting in a motor vehicle) is proposed, said shock absorber comprising: - a restraint part; - a first connecting part and a second connecting part, each of which is movable, in particular displaceable, at least piecewise from at least a first position to at least a second position relative to the restraining part; Equipped with According to a first sub-aspect of the third aspect, the first and / or second connecting parts comprise at least one flexible and shear-resistant means, in particular at least one wire section and / or at least one rope section and / or at least one ribbon section. Preferably, the shock absorber further comprises a fixing mechanism configured to selectively, in particular completely, fix or not fix the first and / or second connecting parts relative to the restraining part.

[0016] Alternatively or additionally to the first sub-aspect, according to a second sub-aspect of the third aspect, the first connection part and / or the second connection part may have at least one retainer for at least one electric wire.

[0017] One idea of ​​the first sub-embodiment is to provide a first or second connecting part that is, on the one hand, flexible (i.e., able in particular to change its shape, preferably curvature), but on the other hand, shear-resistant in the sense that it resists deformation, i.e. in particular does not yield or break (like a textile belt, for example), when the restraining part moves towards the body of the child seat (or towards a properly accommodated child). In this respect, textile belts and / or cord parts should not be understood as shear-resistant means.

[0018] Preferably, the respective connecting part (or the flexible and shear-resistant means) is dimensionally stable in the sense that it can change its shape (in use, in particular during translation), but assumes a predetermined shape in the absence of applied external forces (again, unlike, for example, a fabric belt, etc.) In general, the first sub-aspect makes it possible to achieve a simple and reliable adjustment of the shock absorber, in particular a simple and reliable shortening (by pushing or squeezing) of the distance between the shock absorber and the body of the child seat.

[0019] One idea of ​​the second sub-embodiment is that the first connection part or the second connection part has a holder (retaining device) for at least one electric wire (e.g. for transmitting electric signals and / or currents, for power supply). In particular, in the second sub-embodiment, at least one corresponding electric wire (e.g. at least one cable comprising at least one conductor and a covering insulation) may already be provided. The holder is preferably configured to at least partially enclose the electric wire and may, for example, comprise a channel. This allows for a simple and reliable electrical supply to the impact absorber (e.g. for activating or triggering an airbag), which increases safety.

[0020] The body mentioned above may be a child seat (a seat element possibly comprising a seat part and optionally a backrest). Insofar as the child seat has a shock absorber, this shock absorber should not conceptually be classified as the body.

[0021] The child car seat, in particular the main body thereof, may have a seat portion adapted to rest with its underside on a vehicle seat portion and / or base.

[0022] Preferably, the child car seat, in particular its body, also comprises a backrest. The child car seat, in particular its body, may comprise further elements such as one or more side wings, a headrest, support legs and / or a base.

[0023] The shock absorber may include a restraint portion and first and second connecting parts. The restraint portion is preferably configured to capture a child. The restraint portion preferably extends laterally over at least 20 cm, more preferably at least 30 cm. The restraint portion may include padding and / or a fabric cover. Additionally, the restraint portion may optionally include an airbag.

[0024] The constraining portion preferably forms the main body of the shock absorber, which in turn preferably defines at least 60% by weight, more preferably at least 80% by weight, of the entire shock absorber.

[0025] The restraining portion may have a central portion and right and left end portions. The left and right end portions are preferably connected to each other by the central portion. The left and right end portions may extend in the direction of the body of the child safety seat (i.e. have a main direction of extension that points in the direction of the body of the child safety seat). Main direction of extension means in particular the direction in which the respective element or respective part mainly extends. In a rectangular structure, this is, for example, the direction in which the two long sides of the rectangle extend. The central portion may extend (at least essentially) in the left-right direction (relative to its main direction of extension).

[0026] The central portion may be configured to define a first gap between the shock absorber and a seat surface (or seat portion) of the main body of the child car seat in an in-use configuration of the child car seat. If the main body of the child car seat includes a backrest, a second gap is preferably formed between the central portion and the backrest (in an in-use configuration of the child car seat).

[0027] The first gap (and the second gap, if present) is preferably dimensioned so that the child can be accommodated in the child seat with the child's thighs extending at least partially through the first gap and the child's abdomen and / or the child's chest preferably extending at least partially through the second gap.

[0028] The central and end portions may together form a U-shape (in cross section), whereby preferably (in the in-use configuration) the U is open towards the child or body of the child seat.

[0029] A connecting part is preferably understood to mean a structure configured to fasten the restraining part to the body of the child seat, the respective connecting part preferably having - at least essentially - no further function (beyond this fastening effect) for (directly) holding the child, in particular the restraining part.

[0030] The transition from the first position to the second position (of at least a part of the respective connecting part) is understood to mean in particular a corresponding repositioning relative to the restraining part. This repositioning may include a displacement and / or a rotation. The repositioning may also occur partially or completely by a shape change (e.g. by a change in curvature). However, a (partial) displacement of the respective connecting part is particularly preferred, whereby the displacement according to an embodiment can be set by a corresponding guide (in particular a guide rail).

[0031] As an adjustment mechanism for adjusting the respective positions, a mechanism (possibly of multi-component construction, whereby the individual components can either be connected to one another or at least partially not connected to one another) can preferably be understood which makes it possible to vary the shock absorber, or in particular its restraining part, in terms of its distance from the main body of the child seat (and thus the space for the child).

[0032] Generally, the shock absorber (particularly the restraint portion) can be moved towards the main body of the child car seat (to adjust the shock absorber for a smaller child) and away from the main body of the child car seat (to adjust the shock absorber for a larger child).

[0033] Preferably, the shock absorber or its restraining portion can be moved to at least two, or at least three, or at least five different settings, which can be discrete settings or continuous settings.

[0034] A fixing mechanism is preferably understood to mean a mechanism which fixes the respective connecting part with respect to the restraining part, in particular so that no positional change of the connecting part is possible.

[0035] The first connecting part and / or the second connecting part may comprise at least one flexible and / or shear-resistant means, in particular at least one wire section, or at least one rope section, or at least one wall section. In particular in the first and second aspects and in the second sub-aspect of the third aspect, the first connecting part and / or the second connecting part can also be formed by a (non-shape-stable) belt or belt section.

[0036] Possibly, also independently of further features of the third aspect (e.g. in the first aspect and / or the second aspect and / or the first sub-aspect of the third aspect), the first connection part and / or the second connection part may have at least one holder for at least one electric wire, preferably comprising the electric wire itself. In this regard, reference is made to the corresponding remarks in the second sub-aspect of the third aspect.

[0037] The first connecting part and / or the second connecting part may comprise at least one means for deforming, preferably at least piecewise changing its curvature, during the respective transition, which preferably corresponds to the shear resistant means described in the first sub-aspect of the third aspect and / or corresponds to the flexible and / or shear resistant means as described above.

[0038] A (pure) displacement of a first part of the respective connecting part relative to a second part of the respective connecting part (e.g. in a nested solution) should preferably not be understood as deformation. Deformation preferably implies a change in curvature and / or a (material) stretch and / or a (material) compression. The deformation is preferably elastic, so that the original shape is taken up again (especially when the external force acting on the respective connecting part is discontinued). Preferably, the connecting parts move in different directions at least piecewise (where "piecewise" preferably relates to the end parts closer to the restraining part) during their respective (especially synchronous) transitions. The different directions can form an angle of, for example, at least 90°, possibly at least 120° or (at least approximately) 180°.

[0039] Alternatively or additionally, the first connecting part and / or the second connecting part, during the respective transitions, move at least piecewise (where "piecewise" preferably relates to the end parts closer to the restraining part), in a direction that deviates from the direction of movement (during the displacement of the restraining part to adjust the shock absorber) by less than 180° (possibly less than 150° or less than 120°, for example at least essentially 90°) and / or by more than 0°, preferably more than 30° or more than 60°.

[0040] In an embodiment, the operative connection comprises at least one transmission. In particular, the transmission is configured to vary at least one of the movement parameters, e.g., force and / or torque. In some cases, the variation of force or torque plays a decisive role. For example, with respect to the transmission, the first connecting part can form a driver and the second connecting part can form a driven part, and / or vice versa.

[0041] The transmission may be a mechanical transmission and / or a hydrostatic transmission, and may be configured to convert at least one torque and / or at least one direction of rotation and / or at least one rotational speed and / or at least one force, in particular at least one force direction and / or force amount.

[0042] The operative connection (in particular the transmission) may comprise at least one toothed structure, preferably at least one gear wheel and / or at least one row of toothed structures.

[0043] The first connecting part and / or the second connecting part may have a toothed structure, in particular a toothed row, which (in each case) can preferably be engaged with a gear (in particular a gear of the transmission), the rotation axis of which is preferably locally fixed relative to the arresting part.

[0044] The gear can be arranged between the toothed row of the one connecting part and the toothed row of the other connecting part. When the toothed row of the one connecting part is moved relative to the gear, the toothed row can rotate the gear, whereby this rotation then preferably causes a movement of the toothed row of the other connecting part. When reference is made in this specification (above and below) to a movement of the respective connecting part, this should be understood to mean in particular (unless otherwise specified) a piecewise movement of the respective connecting part relative to the restraining part. The respective movement is preferably (without further specification) a translational movement or at least includes such a movement.

[0045] The first connecting part can be configured to be connected to the child safety seat in a non-detachable manner or in a manner that can only be detached using a tool. Alternatively or additionally, the second connecting part can be configured to be connected to the child safety seat manually (preferably detachably), for example via a belt tongue-belt buckle pair. In particular, the second connecting part can have a belt tongue that can be inserted in a corresponding manner into a belt buckle of the body of the child safety seat.

[0046] Preferably, a fixing mechanism is provided (in particular the fixing mechanism according to the second aspect or optionally the third aspect), which is preferably configured to selectively, in particular completely, fix or not fix the first connecting part and / or the second connecting part relative to the restraining part.

[0047] According to an embodiment, the fixing mechanism may form a structural unit and / or include a common latching device for locking the first and second connection parts in a mating manner. The common latching device may preferably include a common latch and / or a common recess that can be simultaneously engaged with both the first and second connection parts. Alternatively or additionally, the common latching device may include a latch and / or a recess that can be engaged with only one of the first and / or second connection parts to fix it, thereby realizing fixation of the other of the first and second connection parts (e.g., due to the operative connection). For example, the common latching device may directly lock the first connection part, thereby also indirectly locking the second connection part (e.g., due to the operative connection).

[0048] In an embodiment, the shock absorber may comprise an airbag.

[0049] This object is further solved in particular by a child car seat for mounting on a car seat, which comprises a shock absorber as described above (and below).

[0050] The object is further to provide a device for accommodating a child, preferably as defined above, in particular a child car seat (preferably for a car seat), in particular comprising a shock absorber and / or an Isofix anchoring arrangement, preferably as defined above, - a first connecting part and a second connecting part, each of which is movable, in particular displaceable, at least piecewise from at least a first position to at least a second position relative to the restraining part; - an adjustment mechanism for adjusting the respective positions of the first connecting part and the second connecting part, the adjustment mechanism comprising an operative connection such that the adjustment of one of the first connecting part and the second connecting part results in a corresponding adjustment of the other of the first connecting part and the second connecting part; The above-mentioned problem is particularly solved by an apparatus for accommodating a child, comprising:

[0051] The above-mentioned object is further solved by a method for adjusting a child car seat, preferably as described above, and / or an impact absorber for a child car seat (preferably for mounting on a car seat), preferably as described above, in which each of a first connecting part and a second connecting part is moved, at least piecewise, from at least a first position to at least a second position relative to the body of the child car seat or the impact absorber, such that adjustment of the position of one of the first connecting part and the second connecting part results in a corresponding adjustment of the other of the first connecting part and the second connecting part.

[0052] The above-mentioned object is furthermore particularly solved by a method, preferably as described above, for adjusting a child car seat, in particular as described above, or in particular as described above, in which the first connecting part and the second connecting part are each moved at least piecewise from at least a first position to at least a second position relative to the restraining part of the crash absorber, and the first connecting part and the second connecting part are fixed by a common action occurring centrally relative to the body.

[0053] Further features of the method are evident from the above and following description of the device, and corresponding functional features can be implemented as specific method steps, e.g., if an electrical conductor is present, a method step of conducting an electric current can be implemented for, e.g., signaling and / or energy supply to, e.g., an airbag.

[0054] The first connecting part and the second connecting part are preferably guided on the restraining part.

[0055] Further embodiments are evident from the dependent claims.

[0056] Further features and advantages of the present invention will be explained below with reference to the figures in which the following figures are shown: [Brief explanation of the drawings]

[0058] In the following description, the same reference numbers are used for identical and similarly functioning parts.

[0059] 1 and 2 show a child car seat 10. The child car seat 10, in particular its body (which is a seat element and may preferably define a seat) 25, preferably comprises a headrest 40 having a headrest surface 41, a seat area 20 having a seat surface 21, and a backrest 30 having a backrest surface 31.

[0060] The seat area 20 may be provided with fastening means (e.g. with one or two Isofix hooks) for fastening the child seat 10 to the vehicle seat. On each of the side areas of the seat area 20, optional side elements 23 are provided. On the backrest 30, side bolsters 32 are preferably formed.

[0061] Between the seat area 20 and the backrest 30, in particular between the lateral elements 23 and the lateral bolsters 32, lateral receptacles 33a and 33b may be formed in which the shock absorber 100 can be at least partially received so as to be integrated into the geometry of the seat, in particular so as to be at least partially received in a form-fitting manner. Generally, according to an embodiment, a shock absorber seat is provided.

[0062] The shock absorber 100 is connected to the body 25 of the child safety seat 10, in particular to the lateral receptacles 33a and 33b, in particular in the area of ​​the lateral bolsters 32 and the lateral elements 23, via fastening means 24a and 24b. The body 25 is understood in particular to be that part of the child safety seat that provides the actual seat. Said body can therefore be a complete seat (apart from the safety or restraint device in the form of the shock absorber), in particular with a backrest.

[0063] The shock absorber 100 is preferably removably connected to the body 25 on at least one side (possibly on only one side or on both sides). In one embodiment, the shock absorber 100 can be manually (without tools) removably connected to the body on one side and at least not manually removably connected to the body on the other side (i.e., optionally only removably with tools or never removably connected). Further alternatively, the shock absorber can be manually removably connected to the body on both sides or only removably with tools or never removably connected to the body on both sides.

[0064] The shock absorber comprises a restraining portion 105, which comprises a central portion 104 and two lateral end portions 102 and 103, which, in the fastened state of the shock absorber 100, are preferably located within (or extend into or towards) the associated lateral receptacle 33a or 33b.

[0065] 1 and 2, with the shock absorber 100 partially exposed so that the adjustment mechanism 101 is visible. The first fastening element 111 is visible and can be fastened (e.g., by a screw) in a lateral receptacle 33 in the area between the lateral element 23 and the lateral bolster 32. The first connecting element 112 of the first connecting part 110 can be fastened to the first fastening element 111 by means of a guide on the first fastening element 111.

[0066] 4 to 7 show the adjustment mechanism 101 (of the shock absorber 100) in detail. The adjustment mechanism 101 comprises a first connecting part 110, a second connecting part 120, a guide element 130 and a locking element 140.

[0067] The first connecting part 110 comprises a first driving part 113, a first connecting element 112, and a first fastening element 111. The first connecting part 110 can be connected to the seat body or main body 25 in an area beside the first lateral end portion 102 of the restraining part 105 via the first fastening element (e.g., via a screw).

[0068] The first connecting part 110 may comprise a wire (in particular a metal wire, preferably a steel wire) and may be connected (in particular fastened) to a fastening element 111 .

[0069] The first connecting piece 110 can be connected to a first driving element 113 at the central portion 104 of the constraining portion 105 of the shock absorber 100 .

[0070] According to an embodiment, the second connecting part 120 comprises a second drive element 123, a second connecting element 122 and a second fastening element 121. The second connecting part 120 can be connected to the seat body or to the body 10 via the second fastening element 121 in an area beside the second lateral end portion 103 of the restraining part 105. On this side, the fastening element 121 can be designed as a belt tongue. The belt tongue can be releasably locked or become locked into a suitable belt buckle in the area of ​​the lateral receptacle 33b.

[0071] The second connecting part 120 can be designed as a wire (in particular a metal wire, preferably a steel wire) and can be connected, in particular fastened, to a fastening element 121. The second connecting part 120 can be connected to a second driving element 123 in the central part 104 of the restraining part 105.

[0072] The guide element 130 can be (directly) (in particular fixedly) connected to the arresting part 105 at the central part 104 of the arresting part 105. The guide element 130 can be designed as a guide and comprise guide slots 131 in which the first connecting part 110 and the second connecting part 120 can be guided.

[0073] The first connecting part 110 and the second connecting part 120 can slide along the guide slot 131 (particularly along both edges of the slot) (and thus can be moved from or to the lateral end portions 102 and 103).

[0074] The synchronization element 132 can rotate about a first axis 133 and can be mounted in a guide slot 131 of the guide element 130 and can be provided on the guide element 130. The synchronization element 132 can be designed as a gear or can comprise such a gear.

[0075] A latch opening 134 , into which a latch 142 of a locking element 140 can engage, may be provided on the guide element 130 .

[0076] The first drive element 113 may comprise a first slot 114 which is (possibly exclusively) equipped at its upper edge with first teeth 116 arranged side by side by a first toothed strip 115. At least one edge, preferably the lower edge, of the drive element 113 may be designed with a first recess strip 117 with side by side arranged first locking recesses 118. Alternatively or additionally, a (possibly further) first recess strip with (possibly further) side by side arranged second locking recesses may be provided on the upper edge of the drive element 113.

[0077] The second drive element 123 can have a second slot 124 which (in particular in contrast to the first slot) is equipped (in particular exclusively) at its lower edge with second teeth 126 arranged side by side by a second toothed strip 125. A second recess strip 127 with second locking recesses 128 arranged side by side can be provided on at least one edge, preferably on the lower edge, of the drive element 123. Alternatively or additionally, a (possibly further) second recess strip with (possibly further) second locking recesses arranged side by side can be provided on the upper edge of the drive element 123.

[0078] The first drive element 113 and the second drive element 123 can be guided in the guide element 130 (particularly in the guide slot 131) so that they can slide in different (particularly opposite) directions, and the slots 114 and 124 preferably overlap at least partially.

[0079] Due to the overlap of the slots 114 and 124, the synchronizing element 132, which is preferably designed as a gear, can engage with and interact with the first toothed strip 115 of the first and second slots at the top and the second toothed strip 125 of the first and second slots at the bottom, thus establishing an operational connection between them.

[0080] The drive elements 113 and 123 are arranged one behind the other in such a way that, in particular, their locking recesses 118 and 128 at least partially and temporarily overlap when the drive elements slide in opposite directions. The locking element 140 is preferably mounted (below the guide element 130) to be rotatable about a second axis 143, so that the latch 142 can engage with the latch opening 134 of the guide element 130 and / or with the locking recesses 118 and 128 (with the first locking recess 118 and the second locking recess 128 overlapping), thereby locking the drive elements 113 and 123 against sliding in the guide slot 131.

[0081] Alternatively or additionally, latch 142 and / or a further latch can engage with the above-mentioned second locking recess alternatively or additionally provided on the respective upper edge of each drive element 113 and 123. If an additional latch is provided, this additional latch can be securely coupled to latch 142 in such a way that the additional latch can be actuated - or not - by latch 142 in a single movement.

[0082] Additionally, an actuation portion 144 may be provided on locking element 140 that can be actuated to release latch 142 from recesses 118 and 128 , such as unlocking drive elements 113 and 123 .

[0083] The locking element 140 can be spring loaded by a spring 141, which allows the latch 142 to be forced into a locked position (and potentially only be released by applying force to an actuating portion 144).

[0084] When the actuation portion 144 is actuated and the shock absorber 100 is subsequently pulled while the lock is released, the first drive element 113 can move within the guide slot 131 away from the central portion 104 towards the first lateral end portion 102 (and be at least partially pulled out of the central portion 104). In the same manner and at the same time, the second drive element 123 can also move within the guide slot 131 away from the central portion 104 towards the second lateral end portion 103 (and be at least partially pulled out of the central portion 104).

[0085] Due to the interaction of the preferably provided synchronizing element 132 with the toothed strips 115 and 125 (or teeth 116 and 126) of the drive elements 113 and 123, the movement (and thus the length adjustment) is synchronous, regardless of whether it is pulled exactly in the middle of the shock absorber 100 or rather on one side near the lateral end portions 102 and 103. This achieves that the same length change occurs on both sides, preventing, for example, the shock absorber from being positioned less firmly (closer to the child) on one side than on the other.

[0086] Once the user has adjusted the appropriate length of the shock absorber 100, they can release the actuating portion 144 and the latch 142 can relock the two drive elements 113 and 123 together in the corresponding locking recesses 118 and 128.

[0087] 8 to 13, further preferred features of the connection pieces 110 and 120 can be seen. In particular, it can be seen in Figures 8 and 9 that the first connection element 112 can be enclosed in a cover 150, which is preferably ribbon-shaped.

[0088] In FIG. 10 it can be seen that the second connecting part 120 can have a belt tongue 156 .

[0089] According to FIG. 11, the second connecting part 120 can also have a (ribbon-shaped) cover 151 .

[0090] At least (or exclusively) the cover 150 of the first connecting part 110 may have at least one channel 152 (possibly another channel 153) in which the connecting element 112 is guided at least partially (e.g., over at least 50% of its length). The channels 152 and 153 may be round (circular) in cross section. Alternatively or additionally, the cover 150 may have at least one or exactly one connecting cable channel 154 in which an electrical connecting cable can be guided. The connecting cable channel 154 may have, for example, an elongated cross section (whereby the length of the cross section may be at least twice, or at least five times, and / or at most 20 times the width of the cross section). The connecting cable channel 154 is preferably located between the channel 152 and the channel 153. This allows the cable 155 to be held particularly securely.

[0091] The cable 155 may be configured to provide electrical energy to components of the impact absorber 100 and / or to transmit signals to, for example, an airbag triggering mechanism.

[0092] In this respect, it should be pointed out that all the above-mentioned parts, considered individually and in any combination, and in particular the details shown in the drawings, are claimed as essential to the invention, modifications of which are within the knowledge of those skilled in the art.

[0093] Furthermore, it should be pointed out that the widest possible scope of protection is sought. In this regard, the disclosure encompassed by the claims may also be specified by features that are recited using further features, even if these further features do not necessarily have to be included. It should be expressly pointed out that parentheses and the term "in particular" are intended to emphasize optional characteristics of features in the respective context (this does not mean, conversely, that a feature should be considered mandatory in the corresponding context, unless such indication exists). The term "element" should preferably denote an integral structure, which in turn can be connected to at least one other structure (to form a unitary and / or immovable whole structure) or which can be separated from all other structures.
