Description

[0001] The invention relates to a protective module for limiting and / or blocking movement between two structural parts and / or a seating function of a vehicle seat in a crash or during normal use, and to a vehicle seat with at least two structural parts and such a protective module. State of the art

[0002] From DE 10 2023 132 496 A1, an adjustment unit for a vehicle seat is known, wherein the adjustment unit has a rotary lever coupled to a floor lock of the vehicle seat, wherein the rotary lever is movable between a first rotary lever position and a second rotary lever position, wherein the adjustment unit has a locking device coupled to a seat adjustment fitting of the vehicle seat, which is movable between a first position, when a backrest of the vehicle seat is arranged in a use position, and a second position, when the backrest is arranged in a non-use position, wherein the locking device prevents or releases the rotary lever from moving from the first rotary lever position to the second rotary lever position. Task

[0003] The invention is based on the objective of providing a novel protective module for limiting and / or blocking movement between two structural parts and / or a seating function of a vehicle seat in a crash or during normal use, in particular a modular system for vehicle seats of different block heights and for vehicle seats with structural parts to be limited and / or blocked relative to each other, as well as a corresponding vehicle seat. Solution

[0004] With regard to the protective module, the problem is solved according to the invention by the features specified in claim 1. With regard to the vehicle seat, the problem is solved according to the invention by the features specified in claim 11.

[0005] Advantageous embodiments, which can be used individually or in combination with each other, are the subject of the dependent claims.

[0006] The object is achieved according to the invention by a protective module for limiting and / or blocking a movement between two structural parts and / or a seating function of a vehicle seat in a crash or in normal use, wherein the protective module comprises at least a control unit, a protective unit and a coupling element arranged between the control unit and the protective unit, which is variable in length and couples the control unit and the protective unit to each other in such a way that a movement of the control unit can be transferred to the protective unit.

[0007] Because the protection module comprises at least a control unit, a protection unit, and a coupling element located between the control unit and the protection unit, a fully functional protection module can be formed from only a few components. The protection module can be easily adapted to different conditions, such as limiting and / or blocking conditions, as well as to limiting and / or blocking the movement of different structural parts relative to each other in a crash or during normal use. Furthermore, a protection module assembled from the aforementioned components can be adapted to differently designed vehicle seats, for example, with different seat base heights, different seat frame components, seat structure components, and / or seat functions. In particular, the protection module can be designed to be compact and cost-effective.

[0008] Because the coupling element is variable in length and couples the control unit and the protection unit in such a way that movement from the control unit can be transferred to the protection unit, various functions, such as limiting functions and / or blocking functions, can be implemented with just one protection module. Such a protection module can be integrated into differently designed vehicle seats and / or into vehicle seats with different structural components, seat frame components, and / or heights. It should be understood that such a protection module is not limited to use in vehicle seats.

[0009] The protective module can be easily retrofitted and / or pre-assembled as an add-on. It can further enhance the functionality of existing seat adjustment units, for example, by reinforcing them. The protective module can be retrofitted, installed, and removed without affecting existing structural components and / or seat functions. It can be a retrofittable and / or pre-assembled plug-in module, a so-called "plug-and-play" module. The protective module allows for the integration of an additional protective device, such as a locking mechanism, at any point on the vehicle seat, regardless of the seat structure or block height. The protective module can be designed as a modular system, identical for all vehicle platforms.

[0010] The control unit, the protective unit, and the coupling element can be coupled in such a way that, upon initial movement of the control unit, further movement of the control unit relative to the protective unit is limited and / or blocked. The control unit can be assigned to, and in particular attached to, a structural component that may deform and / or warp in the event of a crash, whereby deformation and / or warping of the structural component causes movement of the control unit in the direction of deformation and / or warping. To prevent the structural component from deforming and / or warping further in the direction of deformation and / or warping, the protective unit can be actuated via the coupling element and thus block further movement of the control unit and / or the structural component in the direction of deformation and / or warping.In a further development, the protective unit can additionally engage with a rocker arm of a seat height and / or tilt adjuster via the coupling element, so that movement of the rocker arm relative to the structural component is limited and / or blocked in the event of a crash. This prevents the rocker arm, which may be pivotally mounted on the structural component, for example on a seat frame side panel, from buckling in a crash.

[0011] The control unit and the coupling element can be actuated by a change in the distance between the control unit and the protective unit. For example, the coupling element can be actuated by a linear movement, such as a linear displacement of the control unit relative to the protective unit, for example, perpendicular to a protective axis of the protective unit.

[0012] The control unit and the coupling element can be actuated by a rotation, for example, a turn, pivot, or tilt, of the control unit around a control axis. For example, the coupling element can be actuated by a rotary movement around a control axis. The control axis and the protective axis can be aligned parallel to each other. The protective unit can be movable between a home position and a protected position. Actuation of the coupling element can trigger a position change of the protective unit.

[0013] When the control unit moves, the guard unit can be actuated via the coupling element to limit and / or block movement between the structural component and the rocker arm, as well as height and / or tilt adjustment functions. Movement of the control unit can lead to force transmission via the coupling element, which, for example, activates and / or moves the guard unit, thus locking the guard unit and the control unit against each other.

[0014] The control unit can be rigidly attached to the structural component. The protective unit can be movably designed between a starting position, in particular a normal or non-use position, and a protective position in which the protective unit is engaged with at least one structural component, in particular a limiting engagement and / or a blocking engagement. The protective module can be used in metal structures and plastic structures in which at least one kinematic movement and / or deformation movement is present.

[0015] In one embodiment, the control unit can be movably configured between a starting position, in particular a normal or non-use position, and a control position. In the control position, the control unit can actuate the coupling element. The protective unit can be movably configured between a starting position and a protective position, for example, a blocking position and / or limiting position. The coupling element can couple the control unit and the protective unit such that a movement of the control unit from the starting position to the control position causes a movement of the protective unit from the starting position to the protective position, wherein in the protective position the protective unit limits and / or blocks movement between two structural parts and / or a seating function of a vehicle seat, for example, by locking it.

[0016] The protective module can include a locking mechanism that blocks the movement of a seat structure component through the protective unit based on the activation signal provided by the control unit. The protective unit can be a locking unit. The coupling element can be a pull element, in particular a Bowden cable, or another force transmission element. The control unit and the locking unit can be connected via a Bowden cable.

[0017] The protection module can be used, for example, as a locking module to secure the seats of a second or third row in an easy-entry position, with the same protection module also being usable for seats with different block heights on a platform of different vehicles.

[0018] The control unit can be modular. The protection unit can also be modular. This allows these units to be easily attached to different structures as needed and removed when not required, using simple plug-in elements. The control unit can have at least one first connection point for connecting to a first end of the coupling element. The protection unit can have at least one second connection point for connecting to a second end of the coupling element.

[0019] The control unit can comprise multiple control elements. The protection unit can comprise multiple protection elements.

[0020] Depending on the condition and / or design of the seat structures or the vehicle seat and depending on the seat function, the number, dimensions and / or shape of the control elements and / or protective elements can be variably adapted.

[0021] Individual control elements and individual protective elements can be designed as identical parts.

[0022] In one embodiment, the protective module for limiting and / or blocking movement between two structural parts and / or a seating function of a vehicle seat in a crash or during normal use can comprise at least one control unit rotatable about a first axis, one protective unit rotatable about a second axis, and a coupling element arranged between the control unit and the protective unit. The coupling element can be of variable length and couple the control unit and the protective unit such that a rotation of the control unit about the first axis causes a rotation of the protective unit about the second axis.

[0023] Multiple control elements can be arranged coaxially on a control axis. The control unit can comprise at least a rotary shaft, a control lever pivotally mounted on the rotary shaft, and a spring element. The spring element can be a return element. Multiple protective elements can be arranged coaxially on a protective axis. The protective unit can comprise at least a rotary shaft, a protective lever pivotally mounted on the rotary shaft, and a spring element. The spring element can be a return element. The control unit and the protective unit can be detachably attached to the structure using various fastening techniques, such as rivets and / or screws. If a protective module is integrated, it can be easily removed without altering the seat structure and / or the vehicle seat.The protection module can then be reused. However, the possibility of a permanent connection cannot be ruled out.

[0024] The modularity of the protection module offers the possibility of being installed in so-called JIT (Just-In-Time) systems and reducing the number of end pieces in systems.

[0025] The object of the invention is further achieved by a vehicle seat comprising at least a first structural part, a second structural part movable relative to the first structural part in normal use or in the event of a crash, and at least one protective module for limiting and / or blocking movement between the two structural parts and / or a seat function in normal use or in the event of a crash. Movement is understood to mean, for example, both an adjustment movement between two structural parts for setting a seat function, for example in normal use or normal operation, and a deformation of a structural part, for example in the event of a crash. The protective module comprises at least one control unit, one protective unit, and a coupling element arranged between the control unit and the protective unit, the length of which is variable. The control unit is associated with the first structural part.The protection unit is assigned to the second structural part. The coupling element is arranged between the control unit and the protection unit, and thus between the first and second structural parts, whereby the coupling element couples the control unit and the protection unit to each other in such a way that a second movement of the control unit triggered by a first movement of the first structural part can be transferred to the protection unit and the second structural part.

[0026] The first movement of the seat structure component can be an adjustment, deformation, or shifting movement. In particular, the first movement can be linear. The second movement of the control unit can be a pivoting and / or sliding movement.

[0027] The first movement of the first structural part actuates the control unit, whereby the coupling element exerts a tensile force on the protective unit and actuates the protective unit to limit and / or block a third movement of the second structural part. The third movement can be a pivoting and / or pushing movement. The protective unit can perform a fourth movement, for example, a pivoting and / or pushing movement, in particular a blocking and / or limiting movement.

[0028] The control unit can be configured to be actuated, or activated, by a first movement of the first structural component, for example, a linear movement. When the control unit is actuated, the coupling element can trigger the protective unit, which is configured to limit, block, or prevent a third movement, such as a rotational movement, of the second structural component. In the event of a crash, the control unit can be actuated by a deformation of the first structural component, and in normal use by an adjustment movement of the first structural component. At least one of the structural components can be a rocker arm, a seat frame side panel, a crossbar, a drive unit, a fitting, or a rail element.

[0029] In summary, and in other words, the invention provides a modular and multifunctional protective device that can be used to improve various adjustment units, for example, a backrest adjustment, easy-entry seat adjustment, seat height adjustment, seat tilt adjustment, thigh support adjustment, and to improve various protective functions, such as limiting deformation of a seat surface part, a backrest part and / or a rocker arm in the event of a crash.

[0031] Corresponding parts are marked with the same reference symbols in all figures.

[0032] One in the Fig. A schematically represented vehicle seat 100 is described below using three mutually perpendicular spatial directions. A longitudinal direction x of a vehicle seat 100 installed in a vehicle runs largely horizontally and preferably parallel to a longitudinal direction of the vehicle, which corresponds to the vehicle's usual direction of travel. A transverse direction y, perpendicular to the longitudinal direction x, is also horizontally oriented in the vehicle and runs parallel to a transverse direction of the vehicle. A vertical direction z runs perpendicular to the longitudinal direction x and perpendicular to the transverse direction y. In a vehicle seat 100 installed in a vehicle, the vertical direction z preferably runs parallel to a vertical axis of the vehicle.

[0033] The position and direction designations used, such as front, rear, top, and bottom, refer to the viewing direction of an occupant seated in vehicle seat 100 in a normal seating position, whereby the vehicle seat 100 is installed in the vehicle, in a suitable position for passenger transport with the backrest 104 upright, and oriented in the direction of travel as usual. However, the vehicle seat 100 can also be installed or moved in a different orientation, for example, transversely to the direction of travel. Unless otherwise described, the vehicle seat 100 is designed to be mirror-symmetrical about a plane perpendicular to the transverse direction y.

[0034] The backrest 104 can be pivotally mounted on a seat section 102 of the vehicle seat 100. For this purpose, the vehicle seat 100 can optionally include a fitting 106, in particular an adjustment fitting, swivel fitting, locking fitting or wobble fitting.

[0035] The position and direction specifications used, such as radial, axial, and circumferential, refer to a rotation axis 108 of the fitting 106. Radial means perpendicular to the rotation axis 108. Axial means in the direction of or parallel to the rotation axis 108.

[0036] The vehicle seat 100 can optionally include a longitudinal adjustment device 110. The longitudinal adjustment device 110 comprises, for example, a rail arrangement 112 with a first rail element 114 and a second rail element 116. The first rail element 114 is adjustable in the longitudinal direction x relative to the second rail element 116. The first rail element 114 is attached to the seat part 102. The second rail element 116 is attached to a structural element of a vehicle, for example, a vehicle floor.

[0037] For clarity, the first rail element 114 will be referred to as the upper rail 114 in the following description. This upper rail 114 (also called running rail or carriage) is assigned to the vehicle seat 100 and designed to support this vehicle seat 100. The second rail element 116 will be referred to as the lower rail 116. The lower rail 116 is fixed and, for example, connected to the floor of a vehicle.

[0038] The vehicle seat 100 can be provided with a plurality of protective modules 200 according to the invention for limiting and / or blocking a movement between two structural parts 120, 122 (shown in more detail in the following figures) and / or a seating function 140a to 140c of the vehicle seat 100.

[0039] For example, a first protection module 200 can couple the longitudinal adjustment device 110 and the seat section 102 and be configured as a first seat function 140a to limit and / or block an easy-entry function (also called pitch-lock function) of the vehicle seat 100. This can, for example, prevent the release of the seat section 102 when the seat section 102 is swivelled forward to facilitate access to a rear row of seats, as long as the vehicle seat 100 is moved into a longitudinal position corresponding to an easy-entry position 150 (see Fig. 9 to 11). Even in the event of a crash and under crash loads, the protection module 200 can absorb a force acting on the seat part 102 and on the corresponding adjustment unit.

[0040] For example, a second protective module 200 can be arranged and configured in the area of ​​a thigh support device 160 of the vehicle seat 100 to limit and / or block a second seat function 140b of the thigh support device 160. This allows unwanted further adjustment of the thigh support device 160, for example under load, relative to the seat part 102 to be limited and / or blocked.

[0041] For example, a third protective module 200 can couple the backrest 104 and the fitting 106 and be configured as a third seat function 140c to limit and / or block the backrest swivel function of the backrest 104. In the event of a crash or crash loads on the backrest 104, a force can be transferred to the backrest 104 via the protective module 200, the fitting 106, the seat section 102, and, if applicable, the seat rails into the vehicle body. The coupling elements and the sliding upholstery support of the seat section 102 are not subjected to these crash forces, or only to a minimal degree, and can therefore be designed to be lightweight and cost-effective.

[0042] Additional protective modules (200) can be installed at any location on the vehicle seat (100). The number of protective modules (200) can vary.

[0043] The respective protection module 200 is, in particular, a retrofittable and / or pre-installable add-on module that can provide additional support for already installed adjustment systems and / or seat functions 140a to 140c. Due to the modularity of the respective protection module 200, it can be easily retrofitted and also removed again without affecting or impairing the vehicle seat 100, the adjustment systems and / or seat functions 140a to 140c.

[0044] In particular, the respective protection module 200 is a multifunctional module for limiting and / or blocking and / or locking various parts and functions of the vehicle seat 100.

[0045] Fig. Figure 2 schematically shows a protection module 200 according to a first embodiment according to the invention.

[0046] The protection module 200 for limiting and / or blocking movement between two structural parts 120, 122 (shown in more detail in the following figures) and / or a seating function 140a to 140c of a vehicle seat 100 in a crash or in normal use comprises at least a control unit 210, a protection unit 220 and a coupling element 230 arranged between the control unit 210 and the protection unit 220.

[0047] The coupling element 230 has a variable length L. The coupling element 230 can be a force transmission element, in particular a traction element and / or a Bowden cable 236. The control unit 210 and the protection unit 220 are coupled to each other via the coupling element 230 in such a way that a movement of the control unit 210 can be transmitted to the protection unit 220 in order to limit, block, and / or lock movement between the structural parts 120, 122, and / or a seating function 140a to 140c.

[0048] The control unit 210, the protection unit 220 and the coupling element 230 are coupled together in such a way that, upon a first movement of the control unit 210, a further movement of the control unit 210 relative to the protection unit 220 is limited and / or blocked.

[0049] According to one embodiment, a movement of the control unit 210 can cause a movement of the protection unit 220. The coupling element 230 can clamp the control unit 210 and the protection unit 220 against each other.

[0050] The Protection Module 200 is, in particular, a retrofittable and / or pre-assembled plug-in module. The Protection Module 200 can be a so-called "plug-and-play" module. The Protection Module 200 offers the possibility, if required, of integrating an additional protective device, such as a locking device, at any point on the vehicle seat 100, regardless of the seat structure, seat design, and seat height. The Protection Module 200 can be a cross-platform modular system.

[0051] The control unit 210 and / or the protection unit 220 can be modular. This simplifies the assembly of the protection module 200. The control unit 210 has at least one first coupling point 212 for connection to a first end 232 of the coupling element 230. The protection unit 220 has at least one second coupling point 222 for connection to a second end 234 of the coupling element 230. When tension is exerted on the coupling element 230 by a movement of the control unit 210, this tension is transmitted via the coupling element 230 to the protection unit 220, enabling the protection unit 220 to be actuated.

[0052] The control unit 210 can be movable, for example, linearly movable or pivotally movable. The control unit 210 can also be indirectly movable. For example, the control unit 210 can be connected to one of the structural parts 120, 122 in such a way that a movement of the structural part 120, 122 also moves the control unit 210. Alternatively, the control unit 210 can be directly movable, in which case the control unit 210 is movable relative to the structural part 120, 122. A movement of the structural part 120, 122 can cause a movement of the control unit 210.

[0053] The protective unit 220 is designed to limit and / or block the movement between two structural parts 120, 122 and / or the seating function 140a to 140c. For this purpose, the protective unit 220 can be movable, for example, pivotally movable or linearly movable. The protective unit 220 can, for example, be arranged on the other of the structural parts 120, 122 and be movable relative to this structural part 120, 122.

[0054] Using suitable reset means, the control unit 210 and the protection unit 220 can be reset to an initial position 300.

[0055] The coupling element 230 can be movably arranged between the control unit 210 and the protection unit 220.

[0056] The control unit 210 and the coupling element 230 can be actuated by a change in the distance between the control unit 210 and the protective unit 220. This change in distance can cause a tensile force, triggered by the control unit 210, at the first end 232 of the coupling element 230. The tensile force is transmitted via the coupling element 230, for example, the Bowden cable 236, and the second end 234 of the coupling element 230 to the protective unit 220, thereby actuating the protective unit 220. Alternatively or optionally, the control unit 210 and the coupling element 230 can also be actuated by a rotational movement of the control unit 210 about a control axis 214 (in Fig. 3 shown) can be operated. The protection unit 220 can be switched between a starting position 300 (in Fig. 8 shown) and be movable in a protective position 302 (in Fig. (shown in Figures 9 to 11). For example, the protection unit 220 can be extended around a protection axis 224 (in Fig. (3 shown) be rotatable. The control axis 214 and the protection axis 224 can run parallel to a transverse axis of the vehicle.

[0057] Fig. Figure 3 schematically shows in perspective a vehicle seat 100 with a first block height Ha, wherein the vehicle seat 100 is equipped with a protective module 200 according to the invention. Fig. 2 is provided. The first block height Ha of a seat base of the vehicle seat 100 can, for example, be up to 200 mm.

[0058] The vehicle seat 100 comprises at least a first structural part 120, a second structural part 122 movable relative to the first structural part 120, and at least one protective module 200 for limiting and / or blocking movement between the two structural parts 120, 122 of the vehicle seat 100 during normal use. The protective module 200 comprises at least a control unit 210, a protective unit 220, and a coupling element 230 arranged between the control unit 210 and the protective unit 220, the length L of which is variable and which couples the control unit 210 and the protective unit 220 such that movement of the control unit 210 can be transmitted to the protective unit 220.

[0059] The control unit 210 is assigned to the first structural part 120. In particular, the control unit 210 is arranged and attached to the first structural part 120. The protective unit 220 is assigned to the second structural part 122. The protective unit 220 is arranged and attached to the second structural part 122. The protective module 200, in particular the control unit 210, the protective unit 220, and the coupling element 230, can be attached to the respective structure by simple riveting and / or screwing.

[0060] The seat section 102 comprises a seat section frame 1020. The backrest 104 comprises a backrest frame 1040. The protective unit 220 can be actuated such that it interacts with a third structural section 124, for example, a rocker arm 132 of a height and / or tilt adjustment device 130, which is movably mounted on the second structural section 122. The first structural section 120 can be a rail element 114, for example, a top rail 114, or a rocker arm bracket arranged on the rail element 114. The second structural section 122 can be a seat frame side section 1022 of the seat section frame 1020. In a further embodiment, an additional protective module 200 can be arranged on the backrest frame 1040 to limit and / or block movement between the backrest frame 1040 and the fitting 106.

[0061] In the illustrated embodiment, the coupling element 230 is guided section by section along a fourth structural part 126. The coupling element 230 couples the control unit 210 and the protection unit 220 to each other in such a way that a second movement of the control unit 210, triggered by a first movement of the first structural part 120, can be transferred to the protection unit 220 and the second structural part 122.

[0062] Fig. Figure 4 schematically shows in perspective a vehicle seat 100 with a second block height Hb, wherein the vehicle seat 100 is equipped with a protective module 200 according to the invention. Fig. 2 and analogous to Fig. 3 is provided. For a so-called "pitch lock function" to secure the vehicle seat 100 in the easy-entry position 150 (in Fig. (As shown in Figures 9 to 11), the same 200 mm protection module can be used for different vehicle platforms. The second block height, Hb, can, for example, range from 200 mm to 300 mm.

[0063] Fig. Figure 5 schematically shows an exploded view of a protective module 200 according to a second embodiment of the invention.

[0064] In the illustrated embodiment, the control unit 210 comprises a plurality of control elements 216.1 to 216.7. The protection unit 220 comprises a plurality of protection elements 226.1 to 226.7. The individual control elements 216.1 to 216.7 and individual protection elements 226.1 to 226.7 can be designed as identical parts and thus be implemented cost-effectively.

[0065] The control elements 216.1 to 216.7 are arranged coaxially on a control axis 214.

[0068] Fig. Figure 6 schematically shows a side view of a vehicle seat 100 with a first block height Ha and a protection module 200 according to Fig. 5. Fig. Figure 7 schematically shows a side view of a vehicle seat 100 with a second block height Hb and a protection module 200 according to Fig. 5. The attachment to corresponding structural parts 120 to 124 is analogous to the embodiment shown in the example below. Fig. 3 and Fig. 4. The control unit 210 and the protection unit 220, for example in the form of a locking unit, are independent assemblies that can be used between several block heights Ha, Hb. They are attached to the seat frame 1020, for example by blind rivets. The function of the protection module 200 is independent and it can be added and removed without affecting other assemblies of the vehicle seat 100. The control unit 210 is attached to the upper rail 114. For example, the control lever carrier 218.3 is mounted on the upper rail 114. The control lever 218.4 is pivotally mounted on the control lever carrier 218.3. The protection unit 220 is attached to the seat frame side panel 1022. For example, the protection lever carrier 228.3 is mounted on the seat frame side panel 1022. The protection lever 228.5 is pivotally mounted on the protection lever carrier 218.3.

[0069] Fig. Figures 8 to 11 schematically show in side views a sequence of movements in which the vehicle seat 100 according to Fig. 6 from a design position 152 ( Fig. 8) into an easy-entry position 150 ( Fig. 9 to 11). The first movement is a linear movement of the upper rail 114 relative to the lower rail 116. The first movement of the first structural part 120 can actuate the control unit 210, whereby the coupling element 230 exerts a tensile force on the guard unit 220 and actuates the guard unit 220 to limit and / or block a third movement of the second structural part 122 and optionally also a movement of the third structural part 124. The control unit 210 is located between a starting position 304 ( Fig. 8), in particular a normal position or non-usage position, and a tax position 306 ( Fig. 9 to 11) are designed to be movable. A stop element 250, arranged on the vehicle floor and / or on the lower rail 116, can be provided to actuate the control unit 210. The stop element 250 can initiate or block a pivoting movement of the control lever 218.4. When the vehicle seat 100 is moved from a rear longitudinal position to a front longitudinal position, the control unit 210 can come into or out of contact with the stop element 250, thereby triggering a pivoting movement of the control lever 218.4. In the control position 306, the control unit 210 can actuate the coupling element 230. The protective unit 220 is designed to be movable between an initial position 300 and a protective position 302, for example, a blocking position and / or limiting position.The coupling element 230 can couple the control unit 210 and the protection unit 220 in such a way that a movement of the control unit 210 from the initial position 304 to the control position 306 causes a movement of the protection unit 220 from the initial position 300 to the protection position 302, wherein in the protection position 302 the protection unit 220 limits and / or blocks, for example locks, a movement between at least two structural parts 120 to 124 and / or a seat function 140a to 140c of a vehicle seat 100.

[0070] Fig. Figures 12 to 14 schematically show in side views a sequence of movements in which a protective unit 220 of the protective module 200 moves between a starting position 300 ( Fig. 12 and Fig. 13) and a protective position 302 ( Fig. 14) is moved. The protective unit 220 can engage with a rocker arm 132 of a height adjuster and / or tilt adjuster of the seat through the motion transmission via the coupling element 230, so that movement of the rocker arm 132 relative to the corresponding structural part 120 to 124 is limited and / or blocked in the event of a crash. This prevents the rocker arm 132, which can be pivotally mounted on the structural part 120 to 124, for example on a seat frame side panel 1022, from buckling in the event of a crash.

[0071] The rocker arm 132 includes, for example, at least one detent contour 132.1 at a rocker arm end associated with the protective lever 228.5. The protective lever 228.5 includes at least one counter-detent contour, in particular a detent lug 228.51. During normal operation of the height and / or tilt adjustment of the vehicle seat 100, the protective lever 228.5 can slide along an outer contour 132.2 of the rocker arm 132 with a sliding contour 228.52 ( Fig. 12). In protective position 302 ( Fig. 14) The detent contour 132.1 of the rocker arm 132 and the detent lug 228.51 engage in the detent. This blocks any further movement of the rocker arm 132.

[0072] Fig. Figure 15 schematically shows in perspective view a vehicle seat 100 with a tilt adjustment device 130 and a protective module 200 according to the invention in a third embodiment.

[0073] The rocker arm 132 of the tilt adjustment device 130 comprises, for example, a first rocker arm element 132.3 and a second rocker arm element 132.4, which are connected to each other via a rocker arm joint 132.5. The tilt adjustment device 130 includes at least one spindle drive unit 134 for adjusting the rocker arm elements 132.3, 132.4 relative to each other about the rocker arm joint 132.5. The control unit 210 is arranged on the spindle drive unit 134. The guard unit 220 is arranged on the rocker arm 132, in particular in the area of ​​the rocker arm joint 132.5. The control unit 210 is actuated by a spindle movement. The actuation is transmitted to the guard unit 220 via the coupling element 230. The protective unit 220 can then be moved into a protective position 306 to block the rocker joint 132.5 and thus limit movement of the rocker elements 132.3, 132.4 relative to each other.

[0074] Fig. Figure 16 schematically shows in perspective a thigh support device 160 for a vehicle seat 100, wherein the thigh support device 160 is provided with a protective module 200 according to the invention in a fourth embodiment.

[0075] For example, the protective module 200 can be arranged and configured in the area of ​​a thigh support device 160 of the vehicle seat 100 to limit and / or block the thigh support function of the thigh support device 160. This allows unwanted further adjustment of the thigh support device 160, for example under load, relative to the seat section 102 to be limited and / or blocked. When a thigh support element 166 is extended or during a combined extension movement 162 with a pivoting movement 164, the control unit 210 can be actuated. In an extended position, the control unit 210 can assume a control position 302 and actuate the protective unit 220. The protective unit 220 can then block and / or limit any further pivoting movement 164 about a thigh support axis. The linear extension movement 162 of the leg support element 166 can limit and / or block the pivoting movement 164.

[0076] Fig. Figure 17 schematically shows in perspective view a vehicle seat 100 with a protective module 200 according to the invention in a fifth embodiment.

[0077] The control unit 210 and the coupling element 230 can be actuated by a change in the distance between the control unit 210 and the protective unit 220. For example, the coupling element 230 can be actuated by a linear movement, such as a linear displacement of the control unit 210 relative to the protective unit 220, for example perpendicular to a protective axis 224 of the protective unit 220. In the illustrated embodiment, the control unit 210 consists of only a retaining element 240.

[0078] The control unit 210 can be assigned to, and in particular attached to, a structural part 120 to 126, which may deform and / or deform in the event of a crash, whereby a deformation and / or deformation of the structural part 120 to 126 causes a movement of the control unit 210 in the direction of deformation and / or deformation. In order to prevent the structural part 120 to 126 from deforming and / or deforming further in the direction of deformation and / or deformation, the protective unit 220 can be actuated by means of the motion transmission via the coupling element 230 and block further movement in the direction of deformation and / or deformation of the control unit 210 and thus of the structural part 120 to 126.In a further development, the protective unit 220 can additionally engage with a rocker arm 132 of a height adjuster and / or tilt adjuster of the seat 102 via the coupling element 230, so that movement of the rocker arm 132 relative to the structural part 120 to 126 is limited and / or blocked in the event of a crash. This prevents the rocker arm 132, which can be pivotally mounted on the structural part 120 to 126, for example on a seat frame side panel 1022, from buckling in the event of a crash.
