Description

[0001] Impact shield for a child seat

[0002] Description

[0003] The invention relates to an impact shield for a child seat for installation in a vehicle seat and a corresponding child support device, in particular a child seat and a method for adjusting a child seat or impact shield.

[0004] A child seat with an impact shield is known, for example, from DE 10 2012 100 707 A1. Such impact shields are intended to keep a child seated in the seat, particularly in the event of an accident or sudden braking. Such impact shields can be attached to the child seat itself. In DE 10 2012 100 707 A1, the impact shield is attached using appropriate belt sections.

[0005] Furthermore, solutions are known, for example from DE 10 2022 100 184 A1, in which there is a substantially rigid fastening structure that secures the impact shield to both sides of the child seat, with sections of the fastening structure being movable for adjusting the impact shield (with regard to the child's size). Overall, the prior art solutions are considered to be in need of improvement with regard to adjusting the impact shield (particularly with regard to the child's size).

[0006] The object of the invention is to propose an impact shield for a child seat (for mounting on a motor vehicle seat) that can be adjusted relatively precisely and easily (with respect to the size of a child). Furthermore, the object of the invention is to propose a corresponding child restraint device, in particular a child seat, as well as a corresponding method for adjusting a child seat or impact shield.

[0007] This problem is solved in particular by the features of claim 1.

[0008] In particular, the object is achieved according to a first independent aspect by an impact shield for a child seat (for attachment to a motor vehicle seat), wherein the impact shield comprises:

[0009] - a restraint section (to hold the child, especially in the event of an accident or braking),

[0010] - a first connecting part and a second connecting part, each of which can be transferred, in particular displaced, at least in sections (possibly only in sections) relative to the retaining section from at least one first position into at least one second position, and

[0011] - an adjustment mechanism for adjusting the respective position of the first and second connecting parts, wherein the adjustment mechanism comprises an operative connection which connects the first and second connecting parts to one another and causes the adjustment of one of the first connecting part and the second connecting part to cause a corresponding adjustment of the other of the first connecting part and the second connecting part (and preferably vice versa such that the adjustment of the other of the first connecting part and the second connecting part causes a corresponding adjustment of one of the first connecting part and the second connecting part).

[0012] One idea of ​​the first aspect is to enable a functional link, in particular a synchronization, between the adjustment of the first and second connecting parts by means of the operative connection, in particular such that a load applied to, for example, the first connecting part (e.g., by lateral loading of the restraint section close to the first connecting part) via the operative connection also causes the second connecting part to be correspondingly loaded. This can, in particular, ensure that the restraint section can be adjusted uniformly (e.g., to adapt it or the impact shield as a whole to the child's size).

[0013] In principle, it can be stated, for example, with regard to DE 10 2022 100 184 A1, that in prior art solutions with rigid connecting structures, the connecting structures sometimes cannot be adjusted (completely) independently of one another. However, due to the lack of an effective connection, a one-sided load on the impact shield (for example, a one-sided pull on the impact shield to widen the space between the impact shield and the main body of the child seat for the child) leads to tilting, which ultimately complicates adjustment overall or prevents adjustment under one-sided load.

[0014] An operative connection is understood in particular to mean a connection (between the first and second connecting parts) which transmits a position transfer 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 provided in addition to the retaining section (or a main body thereof) and is partially or fully movable relative to it (in particular displaceable and / or rotatable, for example partially displaceable and partially rotatable). In particular, an operative connection should not already exist if two connecting structures are each connected to the retaining section (or a main body thereof) and are thus (if necessary) connected to one another via the retaining section (or its main body).According to a second (independent, preferably combinable with the first aspect) aspect, an impact body for a child seat is proposed, wherein the impact body comprises:.

[0015] - a retention section with a central section and right and left end sections,

[0016] - a first connecting part and a second connecting part, each of which can be transferred, in particular displaced, at least in sections relative to the retaining section from at least one first position into at least one second position, and

[0017] - 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 retaining section, wherein the fixing mechanism comprises a, in particular form-fitting, fixing device, preferably a latch and an engagement, wherein the fixing device is provided at least in sections on the central section of the retaining section, in particular in the middle of the retaining section.

[0018] One idea of ​​the second aspect is to provide a securing device on the central section of the retaining section. This allows for a simple, reliable securing (fixing) of the first or second connecting part, which improves usability and thus also safety.

[0019] In principle, the retaining section can have a central section as well as a right and a left end section.

[0020] A center of the restraint section is preferably understood to be an area of ​​the restraint section that is at least 20%, preferably at least 30%, or at least 40% of a left-right extension of the restraint section from the two outermost points (left and right, respectively) of the restraint section. References to "left" and "right" here and below refer in particular to the state the impact shield assumes when it is (properly) attached to the child seat.

[0021] According to a third aspect (which can preferably be combined with the first and / or second aspect), an impact shield for a child seat (for mounting on a motor vehicle) is proposed, wherein the impact shield comprises:

[0022] - a retention section and

[0023] - a first connecting part and a second connecting part, each of which can be transferred, in particular displaced, at least in sections relative to the retaining section from at least one first position into at least one second position, wherein the first connecting part and / or the second connecting part according to a first sub-aspect of the third aspect comprises at least one flexible, shear-resistant means, in particular at least one wire section and / or at least one cable section and / or at least one band section. Preferably, the impact body further comprises 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 retaining section.

[0024] Alternatively or in addition 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 can have at least one holder for at least one electrical line.

[0025] One idea of ​​the first sub-aspect is to provide a first or second connecting part which is on the one hand flexible (i.e. in particular can change its shape, preferably bending), but on the other hand is shear-resistant in the sense that when the restraint section moves towards a main body of the child seat (or towards the properly accommodated child) it offers resistance to a change in shape, i.e. in particular does not buckle or fold (like a fabric belt, for example). In this respect, a section of a fabric belt and / or a cord should not be understood as a shear-resistant means. Preferably, the respective connecting part (orAlthough the flexible, shear-resistant means may change its shape (during use, particularly during transfer), it is dimensionally stable in the sense that it assumes a predetermined shape without the action of an external force (again, unlike, for example, a fabric belt or the like). Overall, the first sub-aspect allows for simple and reliable adjustment of the impact shield, in particular a simple and reliable reduction of the distance between the impact shield and the main body of the child seat (by pushing or pushing).

[0026] One idea of ​​the second sub-aspect is that the first or second connection part has a holder (holding device) for at least one electrical line (for transmitting an electrical signal and / or an electrical current, for example for the power supply). In the second sub-aspect, in particular, the at least one corresponding electrical line can already be provided (e.g. at least one cable, comprising, for example, at least one electrical conductor and an enveloping insulation). The holder is preferably configured to envelop the electrical line at least in sections and can, for example, comprise a channel. This allows the impact body to be supplied with electricity in a simple and reliable manner (for example for controlling or triggering an airbag), which increases safety.

[0027] The aforementioned main body can be a seat for the child (seat element, possibly including a seat section and optionally a backrest). If the child seat has an impact shield, this should not be considered part of the main body.

[0028] The child seat, in particular the main body thereof, may have a seat portion configured to rest with a bottom side on a vehicle seat portion and / or a base.

[0029] The child seat, in particular its main body, preferably further comprises a backrest. The child seat, in particular its main body, can have further elements, such as one or more side wings, a headrest, a support foot and / or a base. The impact body can have a retaining section and a first and a second connecting part. The retaining section is preferably configured to catch the child. The retaining section preferably extends over at least 20 cm, more preferably at least 30 cm in a left-right direction. The retaining section can have padding and / or a fabric cover. Furthermore, the retaining section can optionally comprise an airbag.

[0030] The retaining section preferably forms a main body of the catching body, which in turn preferably defines at least 60% by weight, more preferably at least 80% by weight of the entire catching body.

[0031] The restraint section can have a central section and a right and left end section. The left and right end sections are preferably connected to one another by the central section. The left and right end sections can run in the direction of the main body of the child seat (i.e., have a main extension direction pointing towards the main body of the child seat). A main extension direction refers in particular to a direction in which the respective element or section mainly extends. In the case of a rectangular structure, this would be, for example, the direction in which the two longer sides of the rectangle run. The central section can extend (at least substantially) in a left-right direction (with respect to its main extension direction).

[0032] The central portion may be configured to define a first gap between the impact shield and a seat surface (or seat portion) of the main body of the child seat in a use configuration of the child seat. If the main body of the child seat includes a backrest, a second gap is preferably formed between the central portion and the backrest (in a use configuration of the child seat).

[0033] The first gap (and, if present, the second gap) is preferably dimensioned to accommodate the child in the child seat, with the child's thighs extending at least partially through the first gap, and the child's abdomen and / or chest preferably extending at least partially through the second gap. The central portion and end portion may form a U-shape overall (in cross-section), with the U preferably being open toward the child or the main body of the child seat (in a use configuration).

[0034] A connecting part is preferably understood to mean a structure configured to attach the restraining section to the main body of the child seat. The respective connecting part preferably has no further—at least essentially no further—function (beyond this fastening function) for (directly) holding the child, such as, in particular, the restraining section.

[0035] A transition from a first position to a second position (of at least a section of the respective connecting part) is understood to mean, in particular, a corresponding displacement relative to the retaining section. This displacement may comprise a shift and / or a rotation. The displacement may also be partially or completely effected by a change in shape (for example, by a change in the bend). However, a (section-by-section) displacement of the respective connecting part is particularly preferred, whereby the displacement may be fixed by a corresponding guide (in particular a guide rail), depending on the design.

[0036] The adjustment mechanism for adjusting the respective position is preferably a mechanism (possibly multi-part, whereby the individual parts can either be connected to one another or at least partially not connected to one another) which makes it possible to change the impact shield or in particular its retaining section in relation to a distance of the impact shield or retaining section from the main body of the child seat (and thus space for the child).

[0037] In general, the impact shield (especially the restraint section) can be moved towards the main body (to adjust the impact shield for smaller children) and away from the main body of the child seat (to adjust the impact shield for larger children).

[0038] Preferably, the impact shield or its retention section can be adjusted to at least two, three, or five different settings. The different settings can be discrete settings or a continuum of settings.

[0039] A fixing mechanism is preferably understood to mean a mechanism which fixes (secures) the respective connecting part with respect to the retaining section, in particular so that a change in position of the connecting part is not possible.

[0040] The first connecting part and / or the second connecting part can comprise at least one flexible and / or shear-resistant means, in particular at least one wire section or at least one cable section or at least one wall section. In particular, in the first and second aspects and the second sub-aspect of the third aspect, the first and / or second connecting part can also be formed by a (dimensionally unstable) belt or belt section.

[0041] Optionally, also independently of the further features of the third aspect (for example, in the first and / or second aspect and / or the first sub-aspect of the third aspect), the first connection part and / or the second connection part can have at least one holder for at least one electrical line, preferably the electrical line itself. In this regard, reference is made to the corresponding statements regarding the second sub-aspect of the third aspect.

[0042] The first connecting part and / or the second connecting part can comprise at least one means which transforms during the respective transfer, preferably changing its bending at least in sections, wherein the means preferably corresponds to the shear-resistant means according to the first sub-aspect of the third aspect and / or corresponds to the flexible and / or shear-resistant means as mentioned above.

[0043] A (pure) displacement of a first section of the respective connecting part relative to a second section of the connecting part (for example in telescopic solutions) is preferably not to be understood as deformation. Deformation preferably implies a change in the bend and / or a (material) extension and / or a (material) compression. The deformation preferably takes place elastically, so that the original shape is resumed (particularly when external forces with respect to the respective connecting part are eliminated). Preferably, the connecting parts move in different directions at least in sections (whereby "in sections" preferably means end sections that are closer to the retaining section) during the respective (particularly synchronous) transfer. The different directions can, for example, form an angle of at least 90°, possibly at least 120° or (at least approximately) 180°.

[0044] Alternatively or additionally, the first and / or second connecting part moves during the respective transfer at least in sections (wherein sections preferably means end sections that are closer to the retaining section) in a direction that deviates from a direction of movement (during the displacement of the retaining section for adjusting the impact body) by less than 180° (possibly less than 150° or less than 120°, for example at least substantially 90°) and / or more than 0°, preferably more than 30° or more than 60°.

[0045] In embodiments, the operative connection comprises at least one gear. In particular, the gear is configured to change at least one movement variable, e.g., force and / or torque. Sometimes, changing a force or torque plays a decisive role. With respect to the gear, for example, the first connecting part can form the input and the second connecting part the output—and / or vice versa.

[0046] The transmission can be a mechanical and / or hydraulic transmission. The transmission can be configured to convert at least one torque and / or at least one direction of rotation and / or at least one speed and / or at least one force, in particular at least one direction of a force and / or a magnitude of a force.

[0047] The operative connection (in particular the gear) can comprise at least one toothing, preferably at least one gear and / or at least one row of teeth.

[0048] The first and / or second connecting part can have a toothing, in particular

[0049] A row of teeth, each of which is preferably engageable with a gear (in particular of the transmission). The rotational axis of the gear is preferably stationary relative to the retaining section.

[0050] The gear can be located between the row of teeth of one connecting part and the row of teeth of the other connecting part. If the row of teeth of one connecting part is moved relative to the gear, it can set it in rotation, whereby this rotation in turn preferably causes a movement of the row of teeth of the other connecting part. When reference is made here (above and below) to a movement of the respective connecting part, this is intended in particular (unless otherwise stated) to a section-by-section movement of the respective connecting part relative to the retaining section. The respective movement is (without further specifications) preferably a translational movement or at least comprises such a movement.

[0051] The first connector can be configured to be permanently connected to the child seat or to be detachable only with a tool. Alternatively or additionally, the second connector can be configured to be manually (preferably detachably) connected to the child seat, for example, via a belt tongue and buckle pair. Particularly preferably, the second connector can have a belt tongue that can be inserted into a buckle of the main body of the child seat.

[0052] Preferably, a securing mechanism (in particular the securing mechanism according to the second or optionally third aspect) is provided. The securing mechanism is preferably configured to selectively, in particular completely, secure or not secure the first connecting part and / or the second connecting part relative to the retaining portion.

[0053] According to the embodiment, the securing mechanism can form a structural unit and / or have a common locking device for jointly locking the first and second connecting parts. The common locking device can preferably have a common lock and / or a common recess that can be brought into engagement with both the first and the second connecting parts simultaneously. Alternatively or additionally, the common locking device can have a lock and / or a recess that can be brought into engagement with only one of the first and / or second connecting parts for its securing, wherein the other of the first and second connecting parts can be secured (e.g., through the operative connection). For example, the common locking device can directly lock the first connecting part, thereby indirectly locking the second connecting part (e.g., due to the operative connection).

[0054] In embodiments, the impact body may comprise an airbag.

[0055] The object is further achieved in particular by a child seat for installation in a motor vehicle seat, comprising an impact shield as described above (and below).

[0056] The object is further achieved in particular by a child restraint device, in particular a child seat (preferably for a motor vehicle seat), preferably as described above, in particular comprising an impact body, preferably as described above, and / or an Isofix anchoring structure, wherein the child seat comprises:

[0057] - a first connecting part and a second connecting part, each of which can be transferred, in particular displaced, at least in sections relative to the retaining section from at least one first position into at least one second position, and

[0058] - an adjustment mechanism for adjusting the respective position of the first and second connecting parts, wherein the adjustment mechanism comprises an operative connection which causes the adjustment of one of the first connecting part and the second connecting part to cause a corresponding adjustment of the other of the first connecting part and the second connecting part.

[0059] The above-mentioned object is further achieved by a method for adjusting a child seat, preferably as described above, and / or an impact shield, preferably as described above, for a child seat (preferably for attachment to a motor vehicle seat), wherein a first connecting part and a second connecting part are each transferred at least in sections relative to a main body of the child seat or impact shield from at least a first position into at least a second position, wherein an adjustment of the position of one of the first and second connecting parts brings about a corresponding adjustment of the other of the first connecting part and the second connecting part.

[0060] The above-mentioned object is further achieved in particular by a method, preferably as described above, for adjusting a child seat, in particular as described above, or an impact shield, in particular as described above, wherein a first connecting part and a second connecting part are each transferred at least in sections relative to a retaining section of the impact shield from at least a first position into at least a second position, wherein the first connecting part and the second connecting part are fixed relative to the main body by a common central action.

[0061] Further method features emerge from the above and following descriptions of devices, whereby corresponding functional features can be implemented as concrete method steps. For example, if an electrical conductor is present, a method step of passing an electrical current can be performed, e.g., for signal transmission and / or power supply, e.g., for an airbag.

[0062] The first connecting part and the second connecting part are preferably guided on the retaining section.

[0063] Further embodiments emerge from the subclaims.

[0078] In the following description, the same reference numbers are used for identical and equivalent parts.

[0079] 1 and 2 show a child seat 10. The child seat 10, in particular a main body (seat element, which can preferably define a seat) 25 thereof, preferably comprises a headrest 40 with a head support surface 41, a seating area 20 with a seating surface 21, and a backrest 30 with a back support surface 31. The seating area 20 can comprise fastening means (e.g., comprising one or two Isofix hooks) for fastening the child seat 10 to a vehicle seat. An optional side element 23 is provided at each lateral area of ​​the seating area 20. Side bolsters 32 are preferably formed on the backrest 30.

[0080] Between the seat area 20 and the backrest 30, in particular between the side elements 23 and the side bolsters 32, side receptacles 33a and 33b can be formed, into which an impact shield 100 can be at least partially received, so that the impact shield 100 is incorporated into the seat geometry, in particular at least partially received in a form-fitting manner. Overall, according to the embodiment, an impact shield seat is provided.

[0081] The impact shield 100 is connected to the main body 25 of the child seat 10 via fastening means 24a, 24b, in particular at the side mounts 33a and 33b, in particular at an area of ​​the side bolsters 32 and side elements 23. The main body 25 refers in particular to the part of the child seat that provides the actual seat. The main body can thus be a complete seat (in particular comprising a backrest) (apart from the securing or restraint device in the form of the impact shield).

[0082] The impact body 100 is preferably detachably connected to the main body 25 on at least one side (possibly only one side or both sides). In one embodiment, the impact body 100 can be manually detachably connected to the main body (without tools) on one side and at least non-manually connected to the main body on the other side (i.e., possibly only by tool or not at all). Alternatively, it is possible for the impact body to be manually detachably connected to the main body on both sides, or to be connected to the main body on both sides only by tool or not at all.

[0083] The impact shield comprises a retaining section 105, which includes a central section 104 and two lateral end sections 102, 103, which, when the impact shield 100 is fastened, preferably lie in the associated side receptacle 33a or 33b (or extend into or toward these). Fig. 3 shows the child seat 10 according to Figs. 1 and 2 with the impact shield 100 partially exposed, so that an adjustment mechanism 101 can be seen. A first fastening element 111 can be seen, which can be fastened in an area between the side element 23 and the side cheek 32 at the side receptacle 33 (for example, by a screw). A first connecting element 112 of a first connecting part 110 can be fastened to the first fastening element 111 by guides on the first fastening element 111.

[0084] Figs. 4 to 7 show the adjustment mechanism 101 (of the impact shield 100) in detail. The adjustment mechanism 101 comprises the first connecting part 110, a second connecting part 120, a guide element 130, and a locking element 140.

[0085] The first connecting part 110 comprises a first drive part 113, the first connecting element 112 and the first fastening element 111. The first connecting part 110 can be connected to the seat body or main body 25 in an area adjacent to the first lateral end section 102 of the retaining section 105 via the first fastening element (e.g. via a screw).

[0086] The first connection part 110 may comprise a wire (in particular metal wire, preferably steel wire) and may be connected to the fastening element 111 (in particular be fastened thereto).

[0087] The first connecting part 110 can be connected to the first drive element 113 in a central section 104 of the retaining section 105 of the impact body 100.

[0088] According to the 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 main body 10 via the second fastening element 121 in an area adjacent to the second lateral end section 103 of the retaining section 105. On this side, the fastening element 121 can be designed as a belt tongue. The belt tongue can be releasably locked in a suitable belt buckle in the area of ​​the side receptacle 33b.

[0089] The second connecting part 120 can be formed as a wire (in particular a metal wire, preferably a steel wire) and can be connected to the fastening element 121, in particular fastened thereto. The second connecting part 120 can be connected to the second drive element 123 in a central section 104 of the retaining section 105.

[0090] The guide element 130 can be (directly) connected (in particular firmly) to the retaining section 105 in a central section 104. The guide element 130 can be designed as a guide and include a guide slot 131 in which the first and second connecting parts 110 and 120 can be guided.

[0091] The first and second connecting parts 110, 120 can slide along the guide slot 131 (in particular along the edges of the slot) (and thus be moved from or to the lateral end portions 102, 103).

[0092] A synchronization element 132 can be provided on the guide element 130, which can rotate about a first axis 133 and can be mounted within the guide slot 131 of the guide element 130. The synchronization element 132 can be designed as a gear or comprise such a gear.

[0093] A locking opening 134 can be provided on the guide element 130, into which the bolt 142 of the locking element 140 can engage.

[0094] The first drive element 113 can comprise a first elongated hole 114, which is provided (optionally exclusively) on its upper edge by a first toothed strip 115 with adjacent first teeth 116. At least one, preferably the lower, edge of the drive element 113 can be configured by a first recess strip 117 with adjacent first locking recesses 118. Alternatively or additionally, a (optionally further) first recess strip with (optionally further) adjacent second locking recesses can be provided on the upper edge of the drive element 113.

[0095] The second drive element 123 can have a second elongated hole 124, which (particularly in contrast to the first elongated hole) is equipped with adjacent second teeth 126 on (particularly exclusively on) its lower edge by a second toothed strip 125. A second recess strip 127 with adjacent second locking recesses 128 can be provided on at least one, preferably the lower, edge of the drive element 123. Alternatively or additionally, a (possibly further) second recess strip with (possibly further) adjacent second locking recesses can be provided on the upper edge of the drive element 123.

[0096] The first and second drive elements 113, 123 can be guided in the guide element 130 (in particular in the guide slot 131) so that they can slide in different (and in particular opposite) directions, wherein the elongated holes 114 and 124 preferably overlap at least in sections.

[0097] Due to the overlap of the elongated holes 114, 124, the synchronization element 132, which is preferably designed as a gear, can engage at the top into the first toothed rack 115 and at the bottom into the second toothed rack 125 of the first and second elongated holes and interact with them, thus establishing an operative connection between them.

[0098] The drive elements 113 and 123 are, in particular, mounted one behind the other in such a way that their locking recesses 118 and 128 overlap at least partially and temporarily when the drive elements slide in opposite directions. The locking element 140 is preferably mounted (below the guide element 130) so as to be rotatable about a second axis 143 that the latch 142 can engage in the latch opening 134 of the guide element 130 and / or (in a state in which a first and second locking recess 118, 128 overlap) can engage in the locking recesses 118, 128, thus locking the drive elements 113, 123 against sliding in the guide slot 131.

[0099] Alternatively or additionally, the latch 142 and / or another latch can engage in the above-mentioned adjacent second locking recesses provided alternatively or additionally on the respective upper edge of the respective drive element 113, 123. If an additional latch is provided, it can be positively coupled to the latch 142 such that it can be actuated with it—or not—with a single movement. Additionally, an operating section 144 can be provided on the locking element 140, which can be actuated to release the latch 142 from the recesses 118 and 128, thus releasing the locking of the drive elements 113 and 123.

[0100] The locking element 140 can be spring-loaded by a spring 141, whereby the bolt 142 can be forced into the locked position (and can possibly only be released by applying force to the operating section 144).

[0101] If the operating section 144 is actuated and then pulled on the impact shield 100 with the locking mechanism open, the first drive element 113 can move away from the central section 104 in the direction of the first lateral end section 102 in the guide slot 131 (and be at least partially pulled out of it). In the same way and at the same time, the second drive element 123 can also move away from the central section 104 in the direction of the second lateral end section 103 in the guide slot 131 (and be at least partially pulled out of it).

[0102] Due to the preferably provided synchronization element 132 in interaction with the toothed strips 115 and 125 (or the teeth 116 and 126) of the drive elements 113 and 123, the movements (and thus the length adjustment) take place synchronously, regardless of whether the impact body 100 is pulled exactly in the middle or rather on one side near a lateral end section 102, 103. This ensures that the same change in length takes place on both sides, for example to prevent the impact body from sitting less firmly on one side (being less close to the child) than on the other.

[0103] Once the user has made a suitable length adjustment of the impact shield 100, the operating section 144 can be released and the latch 142 locks the two drive elements 113, 123 together again in the appropriate locking recesses 118, 128.

[0104] Further preferred features of the connecting parts 110, 120 can be seen in Figs. 8 and 9, in particular, show that the first connecting element 112 can be enclosed by a preferably band-shaped covering 150. Fig. 10 shows that the second connecting part 120 can have a belt tongue 156.

[0105] According to Fig. 11, the second connecting part 120 can also have a (band-shaped) sheath 151.

[0106] At least (or exclusively) the sheath 150 of the first connection part 110 can have at least one channel 152 (optionally a further channel 153) in which the connecting element 112 is guided at least partially (for example, over at least 50% of its length). The channels 152, 153 can have a round (circular) cross-section. Alternatively or additionally, the sheath 150 can have at least or exactly one connecting cable channel 154 in which electrical connecting cables can be guided. The connecting cable channel 154 can, for example, have an elongated cross-section (wherein a length of the cross-section can be at least twice or at least five times and / or at most 20 times as long as a width of the cross-section). The connecting cable channel 154 is preferably located between the channels 152, 153. This allows the cables 155 to be accommodated particularly securely.

[0107] The cables 155 may be configured to supply electrical energy to a component of the impact shield 100 and / or to transmit a signal, for example to an airbag deployment mechanism.

[0108] At this point, it should be noted that all parts described above, viewed individually and in any combination, particularly the details shown in the drawings, are claimed as essential to the invention. Modifications to these are familiar to those skilled in the art.

[0109] Furthermore, it is pointed out that the broadest possible scope of protection is sought. In this respect, the disclosure contained in the claims can also be clarified by features that are described with further features (even without these further features being mandatory). It is explicitly pointed out that parentheses 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 considered mandatory in the corresponding context). The term "element / elements" should preferably characterize a coherent structure, which in turn can be connected to at least one other structure (to form a possibly integral and / or inherently immobile overall structure) or can be delimited from all other structures.
