Abstract
Description
[0001] The invention relates to a child safety seat for attachment to a vehicle seat.
[0002] From the prior art, e.g. from EP 3 681 757 B1, child safety seat systems are known in which the inclination of a seat element relative to a base can be adjusted. The adjustment of this inclination is considered to be in need of improvement with regard to reliability and safety.
[0003] It is particularly an object of the invention to enable the adjustment of an inclination of a seating element or a child restraint to be carried out in the simplest and safest way possible (especially with regard to operation and / or functionality and / or manufacture).
[0004] The problem is solved in particular by the features of claim 1.
[0005] In particular, the problem (according to a first aspect) is solved by a child safety seat for attachment to a vehicle seat, wherein the child safety seat comprises a base and a child seat adjustable relative to the base between a first reclining position and a second reclining position. The base preferably has a central engagement device, in particular a central beam, which may be designed like a spine, and which comprises a first engagement section and a second engagement section. The child seat in particular has a locking means, wherein the locking means engages in the first engagement section when the child seat assumes the first reclining position relative to the base, and wherein the locking means engages in the second engagement section when the child seat assumes the second reclining position relative to the base.When the central link is described in more detail below, the corresponding properties should also apply to a corresponding central engagement direction (in general, even if it is not designed as a central link), unless this is precluded by the context. Preferably, the central engagement device is elongated. The central engagement device may have a pair of points (which has the greatest distance between them among all pairs of points of the central engagement device), the distance between which is at least 5 times, preferably at least 10 times, and / or at most 100 times, the maximum extent in a direction perpendicular to a corresponding distance line defined by said distance.The central engagement device can have a pair of points (which has the greatest distance between them among all pairs of points of the central engagement device) whose distance is at least 20 cm, preferably at least 40 cm and / or at most 100 cm.
[0006] The first recline position can correspond to a minimum recline position (i.e., as upright a position as possible or maximally) of the child seat relative to the base, and the second recline position can correspond to a maximum recline position (as tilted as possible or maximally) of the child seat relative to the base. Between the minimum and maximum recline positions, there can be further adjustable, and in particular lockable, recline positions, preferably one to six further recline positions, and in particular at least or exactly three further recline positions. Each further recline position preferably involves an additional engagement section.
[0007] In particular, the problem (according to a second aspect, which is preferably combinable with the first aspect) is solved by a child safety seat for attachment to a vehicle seat, wherein the child safety seat comprises a base and a child seat adjustable relative to the base between a first reclining position and a second reclining position, and wherein the child seat has a locking device with an actuating element, a pull element, and a locking element. Actuation of the actuating element preferably drives the locking element by means of the pull element to release itself from engagement with the base.
[0008] The locking means is specifically designed to selectively engage in a first engagement section or a second engagement section of the base in order to lock the first tilt position or the second tilt position.
[0009] In particular, the problem (according to a third aspect, which is preferably combinable with the first and / or second aspect) is solved by a child restraint device, in particular a child safety seat for attachment to a vehicle seat, wherein the child restraint device comprises a base and a child restraint, in particular a child seat, which is adjustable with respect to the base between a first adjustment position and a second adjustment position, in particular a first recline position and a second recline position. The adjustment of the base and the child restraint preferably comprises a projecting element being moved in an opening, wherein the child restraint device comprises a sliding device which, in a first sliding position, covers a section of the opening when the child restraint is in the first adjustment position.The sliding mechanism exposes the section of the opening in a second sliding position when the child intake is in the second adjustment position.
[0010] The child restraint system can be designed, as already described, for example, as a child safety seat with a base and a child seat. It can also be designed as a stroller with a stroller frame as the base and a seat or reclining unit as the child restraint, or as a bedside crib with a frame as the base and a bassinet as the child restraint, or as a highchair with a frame as the base and a seat or rocker as the child restraint. Adjustments can be made, as described, by tilting, rotating (possibly with a limited angle), adjusting the height, shifting, or similar actions. The listed options are not necessarily mutually exclusive (for example, height adjustment can be implemented as a shift).
[0011] In particular, the problem (according to a fourth aspect, which is preferably combinable with the first and / or second and / or third aspect) is solved by a child safety seat for attachment to a vehicle seat, wherein the child safety seat comprises a base and a child seat adjustable with respect to the base between a first reclining position and a second reclining position. The child safety seat comprises a pointer and preferably a scale with a plurality of scale areas, wherein the pointer points to at least one of the scale areas depending on the reclining position.
[0012] In particular, the problem (according to a fifth aspect, which is preferably combinable with the first and / or second and / or third and / or fourth aspect) is solved by a child safety seat for attachment to a vehicle seat, wherein the child safety seat comprises a first support surface, a second support surface and a damping device, wherein the damping device is arranged between the first support surface and the second support surface, wherein the first support surface is arranged to move towards the second support surface in the event of an accident in order to deform the damping device.
[0013] In the context of the present application, the term "means" encompasses whether it is a single corresponding element or several elements. Both possibilities are to be disclosed. Specifically, for example, a locking means can comprise a single locking element or several locking elements.
[0014] Preferably, the first aspect and the second aspect can be combined in such a way that the locking means of the first aspect are identical to those of the second aspect and are thus part of the locking device, and / or that the first and second engagement sections of the second aspect are identical to those of the first aspect and the locking means thus interacts with the central beam.
[0015] Preferably, the tilt adjustment of the first and / or second aspect can be combined with the fourth aspect. In particular, the tilt adjustment according to the first and / or second and / or fourth aspect can also be combined with the third aspect, such that the child restraint system is designed as a child safety seat and the child restraint system as a child seat.
[0016] The child seat can, by design, comprise a seat shell, which may be formed in one piece. "One piece" here means, in particular, that a backrest and a seat surface of the child seat are rigidly connected to each other, whereby the seat shell may, of course, be composed of several individual parts.
[0017] Advantageously, the child seat can include a height-adjustable headrest.
[0018] In a preferred embodiment, the child seat is rotatably mounted on the base. The rotation can be about an axis that is at least substantially horizontal or about an axis inclined by up to 20°, preferably at least 10° and / or at most 18°, for example, at most or exactly 14°. The base may comprise a main body and a rotating body, the rotating body being rotatable together with the child seat relative to the main body. The rotating body is preferably designed as a turntable.
[0019] The child seat can be rotated between a forward-facing and a rear-facing position, each of which is preferably lockable. In some designs, two further positions, particularly sideways (for example, towards a vehicle door), can be provided between the forward-facing and rear-facing positions. These sideways positions may be equipped with a "soft lock," whereby the "soft lock" can be overcome by rotating the seat with increased force (i.e., without pressing a release button or the like). Alternatively, the child seat may be rotatable only between one forward-facing position and two sideways positions, or only between one rear-facing position and two sideways positions.
[0020] Preferably, the child carrier (in the general case of a child carrier device), and in particular the child seat (in the specific case of a child safety seat), is not removable from the base. Here, "not removable" specifically means that the child carrier or child seat cannot be removed without tools (or without an external tool) and without damage, and / or is not intended to be removed by the user. However, it may be possible under certain circumstances for the child carrier or child seat to be removed by qualified personnel, for example, with the aid of special tools.
[0021] Depending on the design, the child carrier, in particular the child seat, may be detachable from the base. Here, "detachable" (as opposed to "non-detachable") means that removal by the user is intended, for example, by operating a designated button and / or switch and / or lever and / or the like, and / or by moving the child carrier or child seat into a position where removal is possible. In this case, detachable fasteners may be provided between the base, in particular the rotating body, and the child carrier or child seat, for example, hooks on the base for gripping a bar on the child seat and / or vice versa.
[0022] The child safety seat may have a longitudinal axis between a rear and a front end. It may be provided that the child safety seat, in particular its base, includes lower anchors for attachment to the vehicle seat and / or a belt guide for a vehicle seat belt. The lower anchors may, for example, be designed as Isofix or LATCH anchors and are preferably located at the rear end, particularly at the bottom of the rear end. Furthermore, the child safety seat, in particular its base, may include a support leg, preferably at the front end. The child safety seat, in particular its base, may also include a top tether, preferably at the rear end, for example, at the top rear, possibly behind the headrest.
[0023] Preferably, the child seat has a seating surface. The child seat can also have side wings, which preferably include side impact protection. The side impact protection can be in the form of a side impact protection element or a side impact protection area. Preferably, it is located closer to the foot end of the child seat than the headrest. The child seat can also have a belt guide for guiding a vehicle lap belt. Preferably, the belt guide is located closer to the head end of the child seat than the seating surface.
[0024] Preferably, the central engagement element, in particular the central bar, and / or a plane of symmetry of the central engagement element, defines a vertical plane, wherein the vertical plane extends particularly in the longitudinal direction of the child safety seat. The width of the central bar is preferably at most 25% of the width of the child seat, wherein the width is the horizontal extent transverse to the longitudinal direction. In particular, the vertical plane can be a plane of symmetry of the central bar.
[0025] The central intervention arrangement, in particular the central bar, may be partially or completely located in a central third, in particular in a central fifth, (referring to a left-right extension of the child seat, in at least one usage configuration of the child seat).
[0026] In a preferred embodiment, the central beam consists at least substantially of metal, in particular steel. The central beam can be covered, at least partially, by an additional part, which can be made, in particular, at least substantially of plastic. The additional part can be configured to guide the locking element, especially even when the locking element is not in a locking state. For this purpose, the additional part can provide a groove, the ends of which can limit the tilt settings and / or recesses can be provided at the bottom of which the locking element can engage with one of the engagement sections.
[0027] Preferably, the central bar can comprise a lower section which preferably extends (in a state of use of the child safety seat) predominantly horizontally, in particular at an angle of less than 45°, preferably at least 5° and / or at most 30°, to the horizontal. The lower section can be curved at least partially, in which case its extent can be considered as the distance from the front end to the rear end of the lower section. The central bar can also comprise an upper section which extends predominantly vertically, at least in the region of the rear end, in particular at an angle of less than 45° to the vertical. The upper section can be curved at least partially, in which case its extent can be considered as the distance from the lower end to the upper end of the upper section.
[0028] Preferably, the central beam is at least partially single-strand, preferably in the lower section or parts thereof. The central beam can branch into two strands such that a gap exists between a left and a right strand of the central beam, preferably in the upper section or parts thereof. Single-strand can mean that two individual structures, in particular profiles and / or tubes, lie (in contact) against each other, or that only one profile or tube runs in the corresponding section. A branching can be achieved, in particular, by having two adjacent individual structures, e.g., two profiles or two tubes, diverge from each other.
[0029] Preferably, the rotating body, in particular the turntable, includes the central beam.
[0030] Preferably, the central frame comprises two mounting sections. One of the mounting sections can include the first engagement section and the second engagement section. Alternatively or additionally, one of the mounting sections can be located in the lower section of the central frame, preferably the mounting section that includes the engagement sections. The other mounting section can be located in the upper section of the central frame. Alternatively or additionally, at least one of the mounting sections can be designed as a guide section that guides the child seat during the transition between the first and second recline positions. In particular, at least the mounting section that does not include the first and second engagement sections can be designed as a guide section.Depending on the design, the guide section can be configured as an elongated hole, or as two opposing elongated holes in the two strands of the central beam, whereby in particular the ends of the elongated hole or holes can limit the inclination adjustment.
[0031] The child seat can be guided, in particular, by a guide element of the child seat, for example a guide rod, which may be designed as a locking rod, being guided by the guide section. Alternatively or additionally, one of the fastening sections may be straight (i.e., not curved), preferably the fastening section designed as a guide section, and / or the other fastening section may be curved, preferably downwards, preferably the fastening section comprising the engagement sections.
[0032] Preferably, the first engagement section and / or the second engagement section (each) is designed as a hole, in particular as a through hole (alternatively as a blind hole) in the central beam, for example in a curve of the central beam. Additionally or alternatively, the first engagement section and / or the second engagement section can be designed as a groove in the central beam and / or be configured for engagement of the locking means from the side (i.e., in a transverse direction) or from above.
[0033] Preferably the locking means comprises a locking element, more preferably two, in particular exactly two, locking elements, wherein the locking element can be designed as a locking pin or locking bolt or as a locking rod.
[0034] Preferably, the locking mechanism is biased towards a locked position. A locked position corresponds to a position in which the locking mechanism engages with one of the engagement sections, thus locking the tilt setting. Preferably, the bias can be generated by means of a spring, for example, a compression spring.
[0035] Preferably, the actuating element is designed as a button, in particular as a push button and / or rotary knob, switch, lever and / or the like. According to the embodiment, the actuating element is rotatably mounted about an axis, in particular a horizontal one.
[0036] Preferably, the actuating element is provided at the head end or the foot end of the child seat. Head end and foot end respectively refer to end sections of the child seat.
[0037] The operating element is designed to be located in a lateral area of the child seat, particularly on a side wing. Specifically, the operating element can be positioned closer to the head end than the seat surface and / or closer to the foot end than the headrest, for example, closer to the head end than the belt guide and / or closer to the foot end than the side impact protection.
[0038] In this embodiment, the locking device comprises two, in particular exactly two, actuating elements, especially when these are arranged in lateral areas (for example, on the left and right side wing) of the child seat. Preferably, the locking device comprises two, in particular exactly two, pull elements.
[0039] Preferably, the traction element is predominantly made of metal and / or plastic (at least by weight percentage). The traction element can be, in particular, a rope and / or strap, for example, a cable pull and / or a Bowden cable and / or a plastic band.
[0040] In this design, the pulling element is formed integrally, particularly monolithically, with the locking element. In the case of multiple pulling elements and locking elements, this means, in particular, that one or each pulling element is integrally or monolithically formed with one of the locking elements. The pulling element and locking element may be operatively connected to each other. In particular, a proximal end of the pulling element may be (directly) connected to the locking element. A distal end of the pulling element may be (directly) connected to the actuating element.
[0041] Preferably, the tensioning element and / or the locking element is guided through the spring.
[0042] The opening is rectangular and / or slotted. Alternatively or additionally, the protruding element is located at a first end of the opening, particularly the slot, when the child restraint is in the first adjustment position. When the child restraint is in the second adjustment position, the protruding element can be located at a second end of the opening, particularly the slot. Here, "first end" and "second end" refer to the respective end sections of the opening.
[0043] Preferably, the protruding element is guided in the opening, particularly in the slot. It can be provided that the protruding element moves, particularly linearly, between the first end of the opening and the second end of the opening during the transition between the first and second setting positions.
[0044] In some designs, the protruding element can be firmly connected to the central beam and / or located at the upper end of the rear section of the central beam.
[0045] Preferably, the sliding device comprises a sliding element, in particular a plate-like one. More preferably, a surface section of the sliding element, which covers the section of the opening in one of the first and second setting positions, is at least substantially smooth.
[0046] Preferably, the child intake or base comprises guide elements, in particular one or more guide rails, for guiding the sliding device, in particular the sliding element.
[0047] It may be provided that the transition of the sliding device from the first sliding position to the second sliding position occurs gravitationally, in particular exclusively gravitationally, i.e., due to the weight of the sliding device itself, especially the sliding element. Alternatively or additionally, an elastic means may be provided that pushes the sliding device towards the protruding element. It may be provided that a transition from the second sliding position to the first sliding position in the second setting position is prevented by the protruding element or at least limited in intermediate positions. It may be provided that the transition of the sliding device from the first sliding position to the second sliding position is driven by the movement of the protruding element in the opening, in particular by sliding and / or by direct contact.
[0048] Preferably, the sliding device comprises a plurality of sliding elements, for example (exactly) two sliding elements, wherein at least two of the sliding elements slide in parallel (but different) sliding planes. The sliding planes can be defined by the guide elements.
[0049] It can be provided that each of the sliding elements is guided in a pair of guide rails (for example, one on the right and one on the left), with each pair of guide rails defining a sliding plane.
[0050] In a preferred embodiment, the pointer is provided on the base, and the scale is provided on the child seat. In particular, the pointer can be located in an upper region of the base, specifically on a housing of the base. The pointer can be injection-molded, particularly on and, in particular, as part of an injection-molded component. The pointer can optionally be color-coded (for example, white on a black injection-molded component). The scale can be located in a lower region of the child seat, specifically on a housing of the child seat. Preferably, the scale is designed as a sticker. The scale can be colored, particularly multi-colored.Advantageously, each compartment (except for labels or illustrations) can be a single color, and / or adjacent compartments can be designed in different colors (so that the compartments can be distinguished from one another by their colors). In other versions, the indicator can of course be located on the child seat and the compartments on the base.
[0051] Preferably, the pointer is positioned opposite the graduation, particularly directly opposite it. For example, the distance between the pointer and the graduation area (especially the graduation area to which the pointer points) can be less than 5 cm, particularly less than 2 cm.
[0052] Preferably, the pointer is designed as a line, in particular as a marker line, or as an arrow, wherein the direction of the line or arrow is preferably perpendicular to a direction of movement of the scale during the transition between the first tilt position and the second tilt position. Insofar as the movement is a rotation or has rotational components, the direction of movement is meant to be local, as close as possible to the pointer.
[0053] Preferably, at least two different adjustment zones are located next to each other, particularly directly adjacent to each other. "Next to each other" here means adjacent to each other in the direction of movement of the child seat when adjusting the recline.
[0054] Preferably, at least two division areas are arranged one above the other. The division areas should be perpendicular to those arranged side by side. In particular, at least two division areas can be at least partially offset from each other.
[0055] Preferably, at least two classification areas are at least partially superimposed and at least partially adjacent to each other.
[0056] Preferably, the pointer indicates at least one or exactly one division in every possible tilt position of the child seat relative to the base, and preferably also in every intermediate position.
[0057] Preferably, each classification area specifies at least one boundary condition, whereby a tilt position is permissible if the pointer indicates an adjustment range whose boundary condition is met. In particular, the boundary condition can be written down in the corresponding classification area, for example, printed, or represented by symbols. "Permissible" can mean that the use complies with legal regulations and / or manufacturer's instructions. An impermissible tilt setting need not necessarily be prevented by design (for example, by a locking mechanism), especially if the permissibility depends on factors such as the weight, size, and / or age of a child in the child seat.
[0058] In particular, the constraint may specify a rotation setting for the child seat, for example, the forward-facing or rear-facing position. Alternatively or additionally, the constraint may specify a weight range and / or a height range and / or an age range for a child seated in the child seat.
[0059] Alternatively or additionally, the boundary condition may require the use of a specific restraint system for a child secured in a child seat, for example, a child seat-specific restraint system such as a harness or impact shield, or a vehicle seat belt. A weight range may require a minimum weight of 4 pounds, or a minimum weight of 20 pounds, or a minimum weight of 40 pounds for a child secured in a child seat, or a maximum weight of 120 pounds, or a maximum weight of 65 pounds, or a maximum weight of 40 pounds, or a maximum weight of 20 pounds (where, of course, a combination of a lower weight limit and an upper weight limit should only be possible if the upper weight limit is higher than the lower weight limit).
[0060] A weight range may prescribe a minimum weight of 2 kg, or a minimum of 9 kg, or a minimum of 15 kg, or a minimum of 22 kg for a child seat, or a maximum weight of 36 kg, or a maximum of 25 kg, or a maximum of 18 kg, or a maximum of 13 kg, or a maximum of 10 kg (whereby a combination of a lower weight limit and an upper weight limit should of course only be possible if the upper weight limit is above the lower weight limit).
[0061] An age range may prescribe a minimum age of 9 months, or a minimum age of 3 years, or a minimum age of 7 years for a child seat, or a maximum age of 12 years, or a maximum age of 7 years, or a maximum age of 4 years, or a maximum age of 15 months (whereby a combination of a lower age limit and an upper age limit should of course only be possible if the upper age limit is higher than the lower age limit).
[0062] A size range may prescribe a minimum height of 40 cm, 70 cm, or 100 cm for a child seat, or a maximum height of 150 cm, 105 cm, or 75 cm (where a combination of a lower and upper size limit should only be possible if the upper size limit is higher than the lower size limit).
[0063] In a specific implementation, a boundary condition in one of the classification ranges could, for example, specify a permissible weight for a child in the child seat, such as 20-65 pounds (one pound = 0.5 kg), as well as the orientation of the child seat, such as forward-facing. In that case, a recline setting of the child seat, where the indicator points to these adjustment ranges, is permissible if the child seat is in the prescribed orientation, such as forward-facing, and if a child in the child seat weighs at least 20 pounds and no more than 65 pounds.
[0064] In another specific implementation, a boundary condition in one of the classification ranges could, for example, stipulate a permissible weight for a child in the child seat, such as 40-120 pounds, as well as the use of the child seat together with a vehicle seat belt as a restraint device for the child (as opposed to child seat-specific restraint devices such as a harness). In this case, a recline setting of the child seat where the indicator points to these adjustment ranges is permissible if it is used together with a vehicle seat belt to restrain the child and if the child in the child seat weighs at least 40 pounds and no more than 120 pounds.
[0065] Insofar as the pointer in some versions points to several, e.g. two, setting ranges simultaneously in at least one tilt setting (for example, if these are arranged one above the other), this means that the tilt setting is permissible if the boundary condition of at least one of the setting ranges to which the pointer points is satisfied.
[0066] Preferably, the child safety seat has a first pointer and a second pointer, and / or the child safety seat has a first division and a second division, in particular one identical to the first. Then the first pointer and the first division can be arranged on one side (right or left) of the child safety seat, and the second pointer and / or the second division can be arranged on the other side (left or right) of the child safety seat. By moving the child seat between the forward-facing and rear-facing positions, the first pointer can point to the second division and / or the second pointer can point to the first division, whereby the pointer can still indicate that the boundary conditions must be met to ensure a permissible tilt setting.
[0067] Preferably, the child safety seat comprises a base, in particular the base already described, and a child seat, in particular the child seat already described, which may be adjustable between a first and a second reclining position relative to the base. Preferably, the child seat then comprises the first support surface, and the base comprises the second support surface.
[0068] For example, the first support surface can be formed by a section of the seat shell, in particular by the underside of the section forming the seat surface. The component forming the first support surface is preferably made of (non-porous) plastic, especially by injection molding. The seat surface may be padded, for example by a cover.
[0069] The second support surface can be formed, for example, by a section of an engagement device and / or a guide device (preferably for guiding a movement of the child seat relative to the base) of the base, in particular the central engagement device. In the exemplary embodiment of the child seat that is tilt-adjustable relative to the base, the damping device preferably rests against the child seat, in particular against the first support surface, and against the base, in particular against the second support surface, both in the first and second tilt positions.
[0070] Generally, no limitations are necessary for the geometry of the first support surface. It can, for example, also be designed as a narrow edge section. The crucial point is that the structure forming the first support surface, such as a wall of the seat shell, is sufficiently strong to support the damping device so that its damping effect, e.g., through deformation, can be achieved.
[0071] Preferably, the damping device is movable relative to the child seat or the base, and optionally also relative to both the child seat and the base. This movement preferably involves displacement, particularly sliding displacement. Rotation or a combination of displacement and rotation is also possible. However, a (pure) deformation of the damping device should not be considered movement. Preferably, the damping device is movable relative to one part of the child seat and the base and fixed (stationary) to the other part, either directly or indirectly.
[0072] In preferred embodiments, the damping device has at least one additional functionality, such as a belt passage and / or a bolt guide.
[0073] In one embodiment, the damping device may have an opening in the form of a slot or several slots, particularly interconnected slots, for a crotch strap (or be rigidly connected to such a strap opening). The crotch strap may have a loop at its lower end that is guided around the central web of a three-web plate. The upper end of the crotch strap may carry a buckle.
[0074] In one embodiment, the damping device may have a bolt guide, in particular for guiding the locking element already described (or be rigidly connected to such a bolt guide). The bolt guide may have a slot, a channel, a groove, a sleeve, and / or the like. The bolt guide may further include a spring, in particular the spring described in connection with the locking element.
[0075] By combining the tilt adjustment and the damping device, it can be exploited that a defined distance between the corresponding structures of the child seat and the base is advantageous for both the tilt adjustment and the damping device (firstly, so that the locking means is always positioned to engage in one of the engagement sections, and secondly, so that the damping device always finds a bearing and a counter-bearing in order to be able to exert its damping effect).
[0076] In a preferred embodiment, the damping device comprises a first support section, a second support section, and a deformation section, wherein the first support section is supported on the first support surface and the second support section is supported on the second support surface. The deformation section is located between the first and second support sections (where the geometric arrangement is less important than the fact that the first and second support sections, under external force, load the deformation section, causing it to deform under sufficiently high load).
[0077] It may be provided that the first support section and / or the second support section is / are designed as a flat surface, for example as a plate, and / or that the first support section and / or the second support section is designed as a rod or tube.
[0078] Preferably, the deformation section is deformed, in particular compressed, in the event of an accident. This allows peak loads for a child in a child seat to be absorbed. The deformation section can be designed so that it buckles under sufficiently high load and / or is subjected to torsion and / or bends and / or breaks and / or tears. According to one embodiment, for example, a bolt can widen a recess (groove) and thus deform the edges of the recess (groove).
[0079] Specific embodiments for the deformation section include honeycomb-like structures that collapse under load, in particular made of aluminum (“honeycomb material”).
[0080] Preferably, the deformation section is made predominantly of metal, for example steel and / or aluminum, at least by weight.
[0081] In one embodiment, the deformation section is weakened at at least one point. This can be achieved, for example, by a taper and / or a hole. The weakening can also be in the form of a kink where the internal material stresses culminate.
