The proposed solution relates to a collision device (1A, 1B), in particular for a vehicle seat (2), comprising a first and a second bearing point (14, 15) for connecting in each case one component (20, 22), and a carrier (10) on which the first bearing point (14) is formed and which has a guide (100) for guiding a movement of the second bearing point (15) relative to the first bearing point (14), wherein the second bearing point (15) is locked in the initial position by means of a locking element (12), which is locked by means of a locking device (13), and after the locking device (13) is unlocked, the locking element can be plastically deformed by a movement of the second bearing point (15) along the guide (100).

Description

Technical Field

[0001] The proposed solution involves a collision device and a vehicle seat equipped with such a collision device. Background Technology

[0002] During a vehicle collision, enormous forces can act on the vehicle seats and the passengers seated there. DE 102021 202 560 A1 describes a member with a deformable section that can reduce the load during a vehicle collision by deforming the deformable section, thus enabling passengers to decelerate more gently.

[0003] Furthermore, the vehicle seats are adjustable, for example, to allow different users to achieve comfortable sitting postures and to adapt to different spatial situations. For instance, the vehicle seats can be installed in the vehicle in a longitudinally adjustable manner using a longitudinal adjustment device to achieve different seat positions along the vehicle's longitudinal axis. The vehicle seats can be adjusted using a height adjustment device to adjust the seat height. The backrest's tilt relative to the seating area can also be adjusted, to name just a few examples. The lever described in DE 10 2021 202 560 A1 is part of the vehicle seat height adjustment system and therefore has a dual purpose.

[0004] To enable passengers (including the driver in autonomous vehicles) to achieve a particularly comfortable seating position during travel, vehicle seats can be designed to transition to a relaxed position where the seating portion and backrest are further reclined. In this position (especially a lying position), passengers can lie flat and, for example, sleep comfortably. However, in this vehicle seating position, in the event of a frontal collision, higher forces are transmitted to the spine because the seatbelt secures the occupant's pelvis rearward. Depending on the specific design of the vehicle seat, this may increase the risk of injury to the occupant. Therefore, in this seating position, reducing collision energy and / or transitioning to a more easily protected posture is particularly advantageous. Utility Model Content

[0005] This invention aims to provide a further improved collision device.

[0006] This task is solved by the subject matter described below in this utility model.

[0007] Accordingly, a collision device is described, particularly for a vehicle seat. The collision device includes a first support portion and a second support portion for connecting one (external to the collision device) component (e.g., the respective components of a vehicle seat). The collision device also includes a carrier on which the first support portion is formed and which has a guide portion for guiding movement of the second support portion relative to the first support portion. It is specified that the second support portion is locked in an initial position by a locking element, which is secured by a locking device, and after the locking device is unlocked, the locking element can be (particularly plastically) deformed by movement of the second support portion along the guide portion.

[0008] In this way, the locking device can selectively prevent or release movement of the second support portion along the guide. In this manner, the locking device can be unlocked, for example, depending on the seat position, effective acceleration, or detection of a vehicle collision, allowing for the selection of optimized behavior of the collision device for each situation. In vehicle seats equipped with one or more such collision devices, this allows the vehicle seat to be moved to another position, for example, one where residual force can be better cushioned. Specifically, for example, the vehicle seat can be shifted from a relaxed position (or other, especially a reclined initial position) to a relatively more upright position, allowing the force to be distributed over a larger area through the seatbelt, significantly reducing the risk of "submersion," i.e., the risk of the seatbelt slipping off. This reduces the load on the spine. One or both support portions can be a swivel support or part of a swivel support, wherein, however, other types of support are also conceivable, such as a fixed, immovable support portion on one of the support portions.

[0009] Because the locking element is deformable to release movement (e.g., deformation of the deformable element, see below), clearance-free support of the second support section can also be achieved. For example, there is no need for clearance in rotatable or movable supports for the locking element. This ultimately results in an improved collision device, leading to an improved vehicle seat. Furthermore, simplified assembly can be achieved, requiring only a single joining process, such as welding.

[0010] The collision device may also include a deformable element that can deform by being guided to move on a guide portion from an initial position relative to the first support portion via a second support portion. This allows for the optional prevention or release of deformation of the deformable element by means of a locking device. The deformable element can be used, for example, to absorb collision energy during a frontal vehicle collision, wherein the material of the deformable element undergoes elastic and / or plastic deformation. Therefore, the collision device can be a collision energy absorber.

[0011] It can be stipulated that the locking device and the locking element are mounted on the carrier respectively, so that they cannot move without damage. Forces acting on the locking element can be introduced into the carrier from the locking element (especially directly, e.g., through contact between the locking element and the carrier) via a first load path. Forces can also be introduced into the carrier from the locking element via the locking device in the locked state via a second load path. The locking element can be weakened by disengaging the second load path using the unlocking locking device. Therefore, the locking device and the locking element can be implemented as immovable parts, and the locking element can be selectively weakened by removing the second load path, especially by selectively deforming it (e.g., when the force exceeds a threshold), rather than by, for example, a movable support. After the locking device is unlocked and the locking element is deformed, they cannot, for example, return to their initial locked position because they have been damaged due to plastic deformation.

[0012] The locking element can be fastened to the carrier, for example, by welding it to the carrier. This method avoids gaps between the locking element and the carrier.

[0013] It can be specified that the locking element has a region (e.g., an arm) that surrounds the second support portion in the initial position. Furthermore, it can be specified that the locking element is elastically and / or plastically deformable by the movement of the second support portion along the guide. This region enables reliable locking in the initial position and controlled release of the support portion in the event of a collision.

[0014] The locking device may include a locking element fixed to a carrier. It can be specified that the locking element, in the locked position, is in an active connection with the locking element, particularly engaged, particularly in contact, and / or (particularly through plastic deformation) capable of transitioning to an unlocked position, in which the active connection and / or engagement and / or contact between the locking element and the locking element is broken. Thus, the locking element can be easily locked in a position that stops the second support portion in its initial position. Unlocking can therefore be performed with a small force, while reliably preventing accidental opening of the locking element. The second load path can be canceled by canceling the active connection, engagement, or contact of the locking element. The first load path, for example, overloads from a defined load, causing targeted deformation of the locking element and allowing movement of the support portion.

[0015] The locking element, for example, has a receiving portion. This receiving portion can, for example, engage in a locking position with a region (e.g., an arm) of the locking element, particularly the end shape of that region (e.g., the arm). This achieves reliable locking using a simple and robust structure.

[0016] The locking element can be shifted from a locked position to an unlocked position by deformation of the locking element. This eliminates the movable support of the locking element, thereby preventing gaps in the support portion of the locking element. It can even be specified that the locking element is pressed against the area of ​​the locking element (e.g., the arm) in the locked position.

[0017] In some implementations, the locking device includes a trigger element. This trigger element allows the locking element to be switched from a locked position to an unlocked position. This enables control over the release of deformation of the deformable element as needed.

[0018] The triggering element is configured, for example, in the form of a pyrotechnic actuator. The triggering element may include an igniter and propellant that can be ignited by the igniter. This allows for particularly rapid release of the deformable element.

[0019] The guide portion defines a guide trajectory, such as a straight or curved guide trajectory, along which the second support portion is guided to move from its initial position relative to the first support portion. It can be specified that the trigger element is configured to apply force to the locking element at an angle relative to the guide trajectory. This arrangement allows for reliable locking. This angle can be a right angle. This ensures that as long as the locking device is not unlocked, even a large force acting on the second support portion will not cause deformation of the deformation element.

[0020] In some implementations, the carrier forms the housing. The locking element is arranged within the housing. This protects the locking element from external influences.

[0021] The carrier, for example, has two shell plates that can be welded together. This allows for a particularly simple manufacturing process while maintaining a robust structure.

[0022] The guide portion is configured, for example, in the form of an elongated hole and / or configured within at least one of the housing plates. This allows for particularly reliable guidance.

[0023] It can be specified that the second support portion includes a bearing sleeve and / or a pin. This sleeve (or pin) can be pressed into a locking element in the initial position. This provides a completely backlash-free support.

[0024] The first support portion and / or the second support portion can be configured, either indirectly or directly, for rotatable support. In this way, the collision device can be used, for example, as a linkage in a height adjustment device, thus fulfilling a dual function.

[0025] The unlocking of the locking device is, for example, irreversible. This results in a particularly simple and reliable structure.

[0026] According to one aspect, a vehicle seat (e.g., having a seating portion and a backrest) is described, which includes one or more collision devices according to any embodiment described herein. For advantages, see the above description.

[0027] It can be specified that the seating component (as one part) is supported on the base (as another part) via one or more impact devices. The weight of the seating component is supported on the base via one or more impact devices, for example. In this way, the impact devices (or multiple impact devices) can fulfill a dual function.

[0028] Each of the respective collision devices can be pivotally supported on the base using one of the two support points. The seating portion can be pivotally supported on the other support point. Thus, the collision device or multiple collision devices can be used, for example, as a linkage of an adjustment device.

[0029] It can be stipulated that the seating portion is supported by one or more impact devices in a manner that allows for height adjustment relative to the base. Each impact device can function as a linkage for height adjustment under normal use, while reducing impact energy in the event of a collision. Attached Figure Description

[0044] Figure 1 A vehicle seat 2 with a seating portion 20 and a backrest 21 is shown. The backrest 21 is arranged in the rear area of ​​the seating portion 20 and is supported on the seating portion 20 in a pivotable manner by means of a fitting 23.

[0045] Furthermore, the vehicle seat 2 includes a height adjustment device 24 for adjusting the seat height of the seating portion 20 (together with the backrest 21) relative to the base 22. Here, the height adjustment device 24 (on each side, i.e., both left and right sides) has a front link 240 in the front region and a rear link 241 in the rear region, by which the seating portion 20 and the backrest 21 are supported on the base 22. The links 240 and 241 are pivotally supported on the base 22, and the seating portion 20 is pivotally supported on the links 240 and 241.

[0046] The seat height relative to the base 22 can be adjusted along the vehicle's vertical axis Z by adjusting the connecting rods 240 and 241 relative to the base 22.

[0047] Here, the seat rail 250 of the longitudinal adjustment device 25 of the vehicle seat 2 acts as a base 22. If the vehicle seat 2 is not equipped with a longitudinal adjustment device 25, for example, then the vehicle floor 3 or a component fixed thereon acts as a base.

[0048] With the aid of the longitudinal adjustment device 25, the seating portion 20 (together with the backrest 21) can be adjusted relative to the vehicle floor 3 along the vehicle's longitudinal axis X. The vehicle's longitudinal axis X extends perpendicular to the vehicle's vertical axis Z. Both the vehicle's longitudinal axis X and vertical axis Z extend perpendicular to the vehicle's transverse axis Y. The pivot axes of the links 240 and 241 extend parallel to the vehicle's transverse axis Y. The pivot axis of the backrest 21 relative to the seating portion 20 extends parallel to the vehicle's transverse axis Y.

[0049] In this example, the longitudinal adjustment device 25 includes two floor rails 251 that are spaced apart along the vehicle's transverse axis Y, wherein, according to Figure 1 In the side view, from the perspective of a user seated in vehicle seat 2, the left floor track 251 can be seen. The corresponding right floor track 251 has a similar structure to the left floor track 251 (e.g., the same or a mirror image). This also applies to the aforementioned links 240, 241 of the height adjustment device 24.

[0050] Floor track 251 can be installed on the vehicle floor 3 and according to Figure 1 In its installed state, it is fixed to the vehicle floor 3 of the vehicle, including the vehicle seat 2. The respective seat rails 250 of the longitudinal adjustment device 25 engage with each of the floor rails 251 in a longitudinally movable manner. The longitudinal adjustment device 25 connects the height adjustment device 24 to the vehicle floor 3.

[0051] Figure 1The vehicle seat 2 is shown in an upright seating position (or position), in which the user can drive the vehicle equipped with the vehicle seat 2 as a driver. The vehicle seat 2 can also be adjusted to a relaxed position (or position), in which the user can, for example, rest or sleep on the vehicle seat 2. In the relaxed position, compared to the upright seating position, both the seating portion 20 and the backrest 21 are further tilted backward (from the perspective of the user sitting on the vehicle seat 2 and looking forward). Specifically, this further tilting occurs such that, when the base 22 is oriented according to its installed state, the torso angle and / or the angle of the longitudinal axis of the backrest 21 relative to the vehicle's vertical axis Z (and relative to the vertical line Z when the vehicle is on a horizontal surface) exceeds 25° (especially exceeding 30°, 40°, or even 50°). The torso angle exemplarily corresponds to the angle of the straight torso line from the hip joint to the shoulder of the user sitting on the vehicle seat 2 relative to the vehicle's vertical axis Z (and / or the vertical line Z). The longitudinal axis of the backrest extends, for example, from the pivot axis of the backrest 21 in the seating section 20 to the upper end edge of the backrest 21.

[0052] Here, the measurement of torso angles is performed, for example, using the standardized H-point measuring device SAE J826 H-POINTMANIKIN (H-point dummy measurement) in accordance with E / ECE / 324 and / or E / ECE / TRANS / 505 (e.g., in accordance with Regulation No. 14, First Amendment / Supplement No. 13 / Reference 1, Annex 4).

[0053] The seating section 20 and the backrest 21 can be moved from an upright seat position to a more reclined, relaxed position by means of the height adjustment device 24, and can move in the opposite direction.

[0054] In this example, the seatbelt pull-out point of the seat occupant's seatbelt 26 is located on the upper end of the backrest 21 (away from the seating portion 20). The retraction mechanism of the seatbelt 26 is mounted on the backrest 21, for example. Therefore, force is applied to the upper end of the backrest 21 by pulling the seatbelt 26. Furthermore, the seatbelt buckle is secured to the seating portion 20 (or alternatively, secured to the seat rail 250, for example).

[0055] In the event of a frontal collision, the weight of the seat occupant is pulled onto the backrest 21 via the seatbelt 26 and forces are applied to the backrest 21. Additionally, within the seatbelt buckle area, forces act on the seating portion 20. These forces are correspondingly oriented forward and upward. Because the seat occupant's torso is relatively more rearward in the relaxed position—for example, at an angle exceeding 35 degrees to the vehicle's vertical axis Z, or even exceeding 45 degrees—a higher force is applied to the seat occupant's spine during a frontal collision.

[0056] Therefore, the front link 240 (or alternatively, the rear link 241) is configured in the form of collision device 1A, such as Figure 2 As shown. Thus, the front suspension of the seating portion 20 can drop, thereby allowing the seating portion 20 and the backrest 21 to move, including rotation, from a relaxed position (or other position) to a relatively more upright position in the event of a vehicle collision.

[0057] As will be further explained below, during the movement from relaxed to upright position, the energy introduced into the vehicle seat 2 due to the impact is absorbed. It should be noted here that the arrangement of the impact device 1A is merely exemplary, and other or additional arrangements of such impact device 1A on the vehicle seat 2 (e.g., on the longitudinal adjustment device 25 and / or accessory 23) are also conceivable.

[0058] Figure 2 One of the collision devices 1A of the vehicle seat 2 is shown. The collision device 1A may also be referred to as a deformable connecting chain or retainer, and according to this example, it is also referred to as a linkage. In this example, the collision device 1A forms a collision energy absorber (for absorbing collision energy).

[0059] The collision device 1A includes a first support portion 14 and a second support portion 15, which are respectively used for connecting components. Specifically, the seating portion 20 is pivotally connected to one of the support portions 14 and 15, and the base 22 is pivotally connected to the other support portion 14 and 15. For this purpose, the support portions 14 and 15 respectively include bolts and / or openings 141 and 152 (e.g., ...). Figure 2 (As shown). Here, by way of example only, the opening 141 of the first support portion 14, designed as a through hole, is provided with a sleeve 140, into which bolts, for example, can be inserted, so as to be rotatably supported. Similarly, by way of example, the second support portion 15 is provided with a through hole, into which bolts, for example, can be inserted. However, other designs are also feasible. Here, the first support portion 14 and the second support portion 15 are respectively configured to rotatably support their respective connecting components. (Compared to...) Figure 1 Together with the connected components (the seating part 20 and the base 22), the two support parts 14 and 15 respectively constitute a rotating support part.

[0060] The collision device 1A also includes a carrier 10 on which a first support portion 14 is disposed. This carrier has a guide portion for guiding the movement of a second support portion 15 relative to the first support portion 14. The second support portion 15 is supported on the guide portion 100 in a manner movable along the guide portion 100. Figure 2The second support portion 15 is shown in its initial position. In the initial position, the second support portion 15 is arranged on the end of the guide portion 100 away from the first support portion 14.

[0061] The carrier 10 includes two shell plates 102 and 103 welded together. The shell plates 102 and 103 are, in this example, stamped and bent parts. The guide portion 100 is constructed in an elongated manner in at least one of the shell plates 102 and 103, in this case, the upper shell plate 103.

[0062] The collision device 1A also includes a deformable element 11. The deformable element 11 can be deformed by the movement of the second support portion 15 from its initial position relative to the first support portion 14 on the guide portion 100, which is plastic deformation. In the example, the second support portion 15 can move toward the first support portion 14, thereby deforming the deformable element 11, as will be further explained below.

[0063] In this specification, the second support portion 15 is locked in the initial position by the locking element 12, which is secured by the locking device 13, and after the locking device 13 is unlocked, it can be deformed by the movement of the second support portion 15 along the guide portion 100 (simultaneously with the deformation element 11 or before the deformation element 11 deforms).

[0064] In the example shown, the guide portion 100 is elongated. The guide portion 100 defines a guide trajectory 101, which is based on... Figure 2 It is straight, but can also be designed into other shapes, such as arcs, especially based on circular arc segments. The deformable element 11 is fastened to the guide portion 100. The deformable element 11 extends along the guide portion 100. The deformable element 11 blocks the guide portion 100. The second support portion 15 is arranged in the guide portion 100.

[0065] Now for reference Figures 3A to 6B The functions of the locking element 12 and the locking device 13 are further explained.

[0066] Figures 3A to 4B The initial position is shown. Here, the locking element 12 surrounds the second support portion 15, specifically, in this example, almost completely around its axis. The locking element 12 has a base 122 and a region that, exemplarily, takes the form of an arm 120. The base 122 is arranged on the end of the collision device 1A remote from the first support portion 14. The base 122 of the locking element 12 is arranged on the side of the second support portion 15 remote from the first support portion 14.

[0067] The locking element 12 is arranged between two housing plates 102 and 103. The housing plates 102 and 103 together form the housing for some parts of the locking element 12, the deformable element 11, and the locking device 13. The locking element 12 is securely held to the carrier 10. Here, the locking element 12 is fixed to the carrier 10, specifically, welded to it.

[0068] The arm 120 of the locking element 12 extends around the second support portion 15 and through the opening 104 of the carrier 10. Here, the opening 104 is formed in the upper housing plate 103, specifically in the side wall. The open end 121 of the arm 120 of the locking element 12 is disposed outside the carrier 10. The arm 120 of the locking element 12 blocks the movement of the second support portion 15 along the guide portion 100. Here, the arm 120 of the locking element 12 locks the second support portion 15 in its initial position. This locks the second support portion 15 in its initial position, especially when engaged. Figure 4A In the visible position, a large force (greater than when the locking element 12 is unlocked) can be transmitted, and the second support portion 15 will not move along the guide portion 100.

[0069] To hold arm 120 in this position, arm 120 is held by locking device 13. For this purpose, locking device 13 includes locking element 130. Locking element 130 is fixed to carrier 10. Locking element 130 has a fastening region 135 fastened to carrier 10. In this example, fastening region 135 is welded to carrier 10. Locking element 130 also has a receiving portion 134. End 121 of arm 120 of locking element 12 is inserted into receiving portion 134. The direction in which end 121 of arm 120 of locking element 12 is inserted into receiving portion 134 is perpendicular to the orientation of guide trajectory 101.

[0070] exist Figure 4A In the position shown, the second support portion 15 (e.g., without gaps) is pressed into the locking element 12 (between the base 122 and the arm 120) and held therein in a form-locking and force-locking manner. Here, the second support portion 15 has a bearing sleeve 150 (alternatively or additionally a pin) inserted here, preferably pressed into the locking element 12, and is exemplary in a cylindrical shape. Furthermore, the end 121 of the arm 120 of the locking element 12 is pressed into the receiving portion 134 such that it conforms to the side of the receiving portion 134 when pressed. The bearing sleeve 150 exemplary here has internal threads into which a bolt can be screwed. This bolt can form a rotating support. Alternatively or additionally, the bearing sleeve 150 can support the bolt in a rotatable manner.

[0071] The locking element 130 engages with the locking element 12 in its locked position and can be switched to an unlocked position, disengaging from the locking element 12. The unlocked position is as follows: Figure 5A and Figure 5BAs shown. Here, the locking element 130 is transformed from the locked position to the unlocked position by deformation. Here, the connecting piece 136, on which the receiving portion 134 is constructed, pivots away from the carrier 10, specifically, it is pried open. A weakened portion of the locking element 130 is provided between the connecting piece 136 and the fastening area 135, at which the locking element 130 is pried open in the unlocked position.

[0072] To move the locking element 130 from the locked position to the unlocked position, the locking device 13 includes a trigger element 131A. The trigger element 131A is oriented perpendicular to the guide trajectory 101. The trigger element 131A is disposed within a housing formed by the carrier 10. Here, the trigger element 131A is disposed adjacent to the second support portion 15. The trigger element 131A extends adjacent to the arm 120 of the locking element 12. Here, the trigger element 131A is oriented parallel to the arm 120. The trigger element 131A is inserted into and held thereon in the sidewall of the carrier 10. The tip of the trigger element 131A is aligned with the locking element 130, specifically, with a protrusion 137 extending toward the trigger element 131A into the opening 104 of the carrier 10.

[0073] In this example, trigger element 131A is based on Figure 8 design.

[0074] like Figure 8 As shown, the triggering element 131A is configured as a pyrotechnic actuator having an igniter 133 and propellant 132 ignitable by the igniter 133. A predetermined bursting point can be formed at the tip of the triggering element 131A as shown. When the propellant 132 is ignited, the triggering element 131A bursts (specifically, at the predetermined bursting point), applying a force F (see [reference needed]) using combustion gases and / or the housing portion and / or an optional piston, etc. Figure 5A The force F is applied to the locking element 130, specifically to the protrusion 137. This causes the locking element 130 to plastically (or alternatively, elastically) bend away from the carrier 10, thereby disengaging from the arm 120 of the locking element 12. This force F is perpendicular to the orientation of the guide trajectory 101.

[0075] It should be noted that other triggering elements can be set instead of pyrotechnic actuators, such as those based on... Figure 9 The trigger element 131B. Therefore, a spring accumulator with a preloaded spring 139 is arranged inside the trigger element 131B. The latching device 138, etc., holds the spring 139 in the preloaded position. (Here, by pulling out) the latching device 138 releases the spring 139, causing it to spring open and apply a force F to the locking element 130, thereby releasing the arm 120 of the locking element 12 as described above.

[0076] Therefore, the unlocking of the locking device 13 is irreversible, which enables a simple and stable structure.

[0077] exist Figure 5A In the position shown, the arm 120 of the locking element 12 is thus still arranged in the initial position, but can now be (plasticly) deformed, or more precisely, pried open, due to the force F acting on the second support portion 15 pointing towards the first support portion 14, especially see Figure 6A .

[0078] Here (or, depending on the arrangement of the deformable element 11, thereafter), the deformable element 11 also deforms, and the second support portion 15 moves along the guide portion 100. Here, the slider 151 of the second support portion 15 is in contact with the edge surface of the guide portion 100. The locking element 12 cannot be opened without damage.

[0079] The locking device 13 and the locking element 12 are respectively mounted on the carrier 10, preventing the locking element 130 and the area (here, the arm 120) from moving without damage. Forces acting on the locking element 12 can be introduced directly into the carrier 10 via a first load path or via a second load path through the locking device 13 in a locked state. The locking element 12 can be weakened by removing the second load path using the unlocking locking device 13.

[0080] Triggering elements 131A and 131B can be triggered by the control system. The control system can detect an impending or already occurring collision and activate triggering elements 131A and 131B accordingly. The control system can optionally detect the position of the vehicle seat 2 and activate triggering elements 131A and 131B only in predetermined positions of the vehicle seat. Triggering elements 131A and 131B can also be triggered by an active acceleration. The driving control of triggering elements 131A and 131B can be implemented through a collision assessment unit integrated into the seat, an acceleration sensor, or a collision assessment unit on the vehicle side, as well as by identifying an impending or already occurring vehicle collision.

[0081] Figure 7 The collision device 1B is shown, and the vehicle seat 2 may optionally or additionally include the collision device 1B. The functional principle is the same as described above, except that the direction of movement of the second support portion 15 in the guide portion 100 is different, that is, it moves away from the first support portion 14. The carrier 10 has a guide portion 100 with a corresponding structure. This increases the distance between the support portions 14 and 15.

[0082] Figure 10The deformable element 11 is shown separately in an exemplary embodiment. The deformable element 11 here has a weakened portion 110. The deformable element 11 is constructed to be thinner than the housing plates 102, 103. The weakened portion 110 may be in the form of a perforation or a recess. Thus, the deformable element 11 allows for particularly precise and uniform deformation. The deformable element 11 may have a smaller material thickness and / or lower material strength compared to the carrier 10. The deformable element 11 fails and deforms, in this example, by a force exceeding a predetermined minimum force acting on the second support portion 15 in the guide portion 100 along the guide portion 100. This releases the guide portion 100 and allows the second support portion 15 to move along the guide portion 100. The guide portion 100 is covered by the deformable element 11 in the initial position of the second support portion 15. The deformable element 11 is elongated.

[0083] Optionally, the deformable element 11 has (e.g., linear, stepped, or exponential) increasing material thickness, strength, and / or stability along its length. This allows, for example, the safe interception of people of different weights. Alternatively or additionally, this gradual increase can be specified before the end position in the guide 100 to prevent hard impacts.

[0084] Alternatively or additionally, the deformable element may also be formed from the opposing edge of the guide portion 100. By applying a force exceeding the minimum, the edge of the second support portion 15 can be folded up, thus enabling movement within the guide portion 100.
