Description

Field of invention

[0001] The present invention relates to a vehicle seating arrangement with the features of the preamble of claim 1. Background of the invention

[0002] In luxury vehicles, familiar seating arrangements with a reclining function typically feature multiple adjustment levels to provide the most comfortable reclining position possible. Each of the corresponding adjustment axes is equipped with its own electric drive to enable synchronous adjustment into the reclining position. However, the large number of electric drives requires high electrical currents and considerable control complexity, resulting in high costs and added weight.

[0003] DE 10 2014 014 138 A1 discloses a vehicle seat that is movable along a guide describing a trajectory curve, wherein the guide is designed such that the vehicle seat can be moved away from the center of the vehicle by a movement along the guide and can be rotated with its front about its vertical axis towards the center of the vehicle. DE 10 2018 204 461 A1 discloses a vehicle seat for mounting on a vehicle structure, comprising a seat section and a backrest, wherein at least the backrest is adjustable into a resting or reclining position, and wherein at least the seat section, in the event of a collision, is pivoted or pivotable upwards about an axis parallel to the transverse direction of the vehicle with a front area facing away from the backrest, wherein an energy absorption device is provided that is effective between the seat section and the vehicle structure in the longitudinal direction of the seat.Reference is also made to DE 10 2020 216 333 A1, DE 10 2020 116 142 A1, DE 10 2007 038 568 B4, JP 2008-049845 A, JP 2019-137229 A and DE 10 2019 129 174 A1.

[0004] The present invention is therefore based on the objective of providing an improved and simplified vehicle seating arrangement for a motor vehicle, which is also more cost-effective to manufacture and has a lower weight. Summary of the invention

[0005] The inventive solution to the problem is achieved by a vehicle seat arrangement with the features of claim 1. Advantageous further developments of the invention are set out in the dependent claims.

[0006] The invention relates to a vehicle seat arrangement for a motor vehicle, comprising a vehicle seat with a seat surface and a backrest, and a guide device for moving the vehicle seat along the guide device, wherein the vehicle seat arrangement further comprises: a mechanical adjustment device configured to increase the inclination of the seat surface and / or decrease the inclination of the backrest by moving the vehicle seat along the guide device from a first position to a second position, characterized in that the adjustment device comprises at least three gears, wherein the seat surface and the backrest are connected to the gears for transmitting a change in inclination.

[0007] By using mechanical components, the adjustment device transmits the movement of the vehicle seat along the guide rail to the seat cushion and / or backrest in such a way that the seat cushion angle is increased and / or the backrest angle is decreased, a comfortable reclining position can be provided without the need for electric drives. Likewise, separate mechanical devices that individually adjust the angle of the seat cushion and / or backrest for the reclining position without moving the vehicle seat along the guide rail are unnecessary. In this case, this movement is not only used to adjust the vehicle seat into the reclining position along the guide rail in the vehicle's longitudinal direction (X-direction), but also simultaneously influences the angle of the seat cushion and / or backrest.The reclining position can thus be achieved with just one movement of the vehicle seat or action by the vehicle occupant. The seat cushion tilt and / or the backrest tilt are therefore subject to forced control by the mechanical adjustment device. In summary, the movement of the vehicle seat along the guide rail is converted by this forced control into an increase in the seat cushion tilt and / or a decrease in the backrest tilt. It is conceivable to increase only the seat cushion tilt, decrease only the backrest tilt, or simultaneously increase and decrease the seat cushion tilt.

[0008] In this case, a "greater seat inclination" can mean a larger acute angle between the seat and the guide mechanism in the second position than in the first position. Similarly, a "smaller backrest inclination" can mean a smaller acute angle between the backrest and the guide mechanism in the second position than in the first position.

[0009] In a preferred embodiment, the mechanical adjustment device comprises a ramp element with a ramp track, wherein the ramp track has a transmission angle to the guide device. This allows the movement of the vehicle seat along the guide device to be easily transmitted for increasing the seat surface inclination and / or decreasing the backrest inclination.

[0010] Preferably, the seat surface is rotatably mounted on a first axis of rotation, and a first ramp section is arranged on the seat surface. When the vehicle seat moves along the guide device from the first position to the second position, this ramp section is guided along the ramp track in such a way that, during this movement, the seat surface is rotated away from the guide device to increase the inclination. This allows for a particularly effective increase in the seat surface inclination.

[0011] In a preferred embodiment, or additionally or alternatively, the backrest is rotatably mounted on a second pivot axis, and a second ramp section is arranged on the backrest. When the vehicle seat moves along the guide device from the first position to the second position, this ramp section is guided along the ramp track in such a way that the backrest is rotated towards the guide device during this movement, thus reducing the inclination. This allows for a particularly effective reduction of the backrest inclination.

[0012] In a further embodiment, a seat segment is preferably rigidly connected to the seat surface and includes the first ramp section. An existing seat surface can be equipped with the additional seat segment for guidance along the ramp track in order to increase the seat inclination.

[0013] In a further embodiment, a seat segment is preferably rotatably mounted with respect to the seat surface and comprises the first ramp section, wherein a control bolt provided on the seat surface is guided along a control cam of the seat segment during rotation of the seat segment, and wherein this rotation of the seat segment causes the rotation of the seat surface. Initially, an existing seat surface can be equipped with the additional seat segment for guidance on the ramp track in order to increase the seat surface inclination. Furthermore, the independent rotations of the seat segment or the seat surface and / or the shape of the control cam allow the seat surface inclination to be better influenced depending on the movement of the vehicle seat along the guide device.

[0014] In a further preferred embodiment, the mechanical adjustment device comprises a cam component with a cam, wherein the cam has a transmission angle to the guide device. This allows the movement of the vehicle seat along the guide device to be transmitted in a simple manner for increasing the seat surface inclination and / or decreasing the backrest inclination.

[0015] Preferably, the seat surface is rotatably mounted on a first axis of rotation, and a cam bolt is arranged on the seat surface for engaging the cam. During movement of the vehicle seat along the guide device from the first position to the second position, the cam bolt is guided by the cam such that, during this movement, the seat surface is rotated away from the guide device to increase the inclination. This allows for a particularly effective increase in the seat surface inclination.

[0016] In all embodiments, it is also conceivable that the adjustment device preferably comprises a coupling element, wherein the seat and backrest are connected to the coupling element for transmitting a change in inclination. In all embodiments, the adjustment device comprises at least three gears, wherein the seat and backrest are connected to the gears for transmitting a change in inclination. The coupling element and / or the gears can transmit a positive control of the seat to the backrest, as described above, or vice versa: For example, when the seat inclination is increased using the ramp element or the cam component, a second positive control for decreasing the backrest inclination can be provided simultaneously.Conversely, if the backrest inclination is reduced, a second forced control for increasing the seat inclination can be provided simultaneously, for example with the ramp element or the backdrop component.

[0017] Finally, a motor vehicle will be provided that includes the vehicle seating arrangement just described. Character description

Detailed description

[0019] Fig. Figure 1A shows a schematic sectional view of an embodiment of a vehicle seating arrangement 10 with a ramp element: The vehicle seating arrangement 10 comprises a vehicle seat 20 with a seat surface 22 and a backrest 24. Preferably, the seat surface 22 and the backrest 24 can be attached to a side panel 26.

[0020] Preferably, the side panel 26 is attached to a guide device 30 for moving the vehicle seat 20 along the guide device 30. More preferably, the guide device 30 comprises a floor rail 32 and a seat rail 34. As in Fig. As can be seen in Figure 1A, the side panel 26 is preferably attached to the seat rail 34. Furthermore, the floor rail 32 is preferably attachable to the floor of a motor vehicle.

[0021] Furthermore, the seat rail 34 is guided on the floor rail 32. In all embodiments, the vehicle seat 20 with the seat rail 34 can be moved by a drive (not shown), preferably in the longitudinal direction of the vehicle (X-direction), on the floor rail 32, which in Fig. 1A is represented by a straight arrow. The drive can be effected in a known manner, for example mechanically by actuation by the vehicle occupant or electrically. In summary, the drive enables the vehicle seat 20 to be moved along the guide device 30 from a first position to a second position.

[0022] According to the invention, the vehicle seat arrangement 10 further comprises a mechanical adjustment device 40, which is designed to increase the inclination of the seat surface 22 and / or decrease the inclination of the backrest 24 by moving the vehicle seat 20 along the guide device 30 from the first position to the second position.

[0023] The mechanical adjustment device 40 is thus designed to transmit a movement of the vehicle seat 20 along the guide device 30 from the first position to the second position to the seat surface 22 and / or to the backrest 24 in such a way that an inclination of the seat surface 22 is increased and / or an inclination of the backrest 24 is decreased.

[0024] To convert the movement of the vehicle seat 20 along the guide device 30 from the first position to the second position into an increase in the seat surface inclination and / or a decrease in the backrest inclination, the mechanical adjustment device 40 preferably comprises a Fig. 1, Fig. 2, Fig. 3, Fig. 4 to Fig. 5 Ramp element 42 shown with a ramp track 42.1, wherein the ramp track 42.1 is, for example, in the Fig. 1, Fig. 3 and Fig. 4 has a first transmission angle α1 and a second transmission angle α2 to the guide device 30. The Fig. 2 and Fig. Figure 5 shows, for example, a ramp track 42.1 with a transmission angle α.

[0025] As in Fig. As shown in Figure 1A, the seat surface 22 is preferably rotatably mounted on a first pivot axis D1. Furthermore, a first ramp section 40.1 of the adjustment device 40 is arranged on the seat surface 22. When the vehicle seat 20 moves along the guide device 30 from the first position to the second position, this ramp section is guided on the ramp track 42.1 such that, during this movement, the seat surface 22 is rotated away from the guide device 30 to increase the inclination, which in Fig. 1B is shown. The rotation of the seat surface 22 is also indicated by a curved arrow in Fig. 1A illustrates.

[0026] The first ramp section 40.1 can be formed in one piece with an element of the seat 22 and / or be attached to the seat 22.

[0027] In summary, the ramp track 42.1 and the first ramp section 40.1 are designed such that, when the vehicle seat 20 moves along the guide device 30 from the first position to the second position, the seat surface 22 is rotated away from the guide device 30 to increase the inclination. Preferably, a distance between the first axis of rotation D1 and the guide device 30 can remain constant or be maintained such that, when the vehicle seat 20 moves along the guide device 30 from the first position to the second position, the seat surface 22 is rotated away from the guide device 30 to increase the inclination. The seat surface 22 is thus subject to positive control by the guidance of the first ramp section 40.1 on the ramp track 42.1 and is rotated away from the guide device 30 to increase the inclination by this positive control.

[0028] While in the embodiment of Fig. 1A and Fig. 1B only the seat tilt is increased in the second position, is in the embodiment of Fig. 2A and Fig. 2B only reduces the backrest inclination in the second position: Preferably, the backrest 24 is rotatably mounted on a second pivot axis D2, and a second ramp section 40.2 of the adjustment device 40 is arranged on the backrest 24, which, when the vehicle seat 20 moves along the guide device 30 from the first position to the second position, is guided on the ramp track 42.1 such that, during this movement, the backrest 24 is rotated towards the guide device 30 to reduce the inclination, which in Fig. 2B is shown. The rotation of the backrest 24 is also indicated by a curved arrow in Fig. 2A illustrates this.

[0029] The second ramp section 40.2 can be formed in one piece with an element of the backrest 24 and / or be attached to the backrest 24.

[0030] In summary, the ramp track 42.1 and the second ramp section 40.2 are designed such that when the vehicle seat 20 moves along the guide device 30 from the first position to the second position, the backrest 24 is rotated towards the guide device 30 to reduce the inclination. Preferably, a distance between the first axis of rotation D2 and the guide device 30 can remain constant or be maintained such that, when the vehicle seat 20 moves along the guide device 30 from the first position to the second position, the backrest 24 is rotated towards the guide device 30 to reduce the inclination. The backrest 24 is thus subject to positive control by the guidance of the second ramp section 40.2 on the ramp track 42.1 and is rotated towards the guide device 30 to reduce the inclination by this positive control.

[0031] Fig. Figure 3 shows another preferred embodiment, which is based, for example, on Fig. 1. Based on: The adjusting device 40 comprises a coupling element 46, wherein the seat 22 and the backrest 24 are connected to the coupling element 46 to transmit a change in inclination. As described above, the seat 22 is subject to forced control by the guidance of the first ramp section 40.1 on the ramp track 42.1 and is rotated away from the guide device 30 by this forced control to increase the inclination of the seat 22. The coupling element 46 forms a second forced control, by which the backrest 24 is rotated towards the guide device 30 to simultaneously decrease the inclination of the backrest 24. Fig. Figure 3 shows only the first position; the second position is not shown for simplicity.

[0032] Alternatively or additionally, it is also conceivable that the embodiment of Fig. 3 on the embodiment of Fig. 2 is based on the fact that, as described above, the backrest 24 is subject to a forced control through the interaction of the second ramp section 40.2 and the ramp track 42.1. The optional coupling element 46 again forms a second forced control, which moves the seat away from the guide device 30 while simultaneously increasing the inclination of the seat surface 22 (not shown).

[0033] Fig. Figure 4 shows another preferred embodiment based on Fig. 3 is based on: A seat segment 50 is rigidly connected to the seat surface 22 and has the first ramp section 40.1. As described above, the seat surface 22 is subject to forced control by the guidance of the first ramp section 40.1 on the ramp track 42.1 and is rotated away from the guide device 30 by this forced control to increase the inclination of the seat surface 22. The optional coupling element 46 forms a second forced control, by which the backrest 24 is rotated via a backrest segment 52 towards the guide device 30 to simultaneously decrease the inclination of the backrest 24. The backrest segment 52 is in Fig. 4 preferably rigidly connected to the backrest 24. Finally, in Fig. Only the first position is shown; the second position is not shown for the sake of simplicity.

[0034] Alternatively or additionally, it is also conceivable that a further embodiment could be based on the embodiment of Fig. 2 is based on the fact that, as described above, the backrest 24 is subject to a forced control through the interaction of the second ramp section 40.2 on the rigidly connected backrest segment 52 and the ramp track 42.1. The optional coupling element 46 again forms a second forced control, through which the seat surface is moved away from the guide device 30 to simultaneously increase the inclination of the seat surface 22 (not shown).

[0035] Fig. Figure 5A shows another preferred embodiment with the vehicle seat 20 in the first position: A seat segment 50 is rotatably mounted with respect to the seat surface 22 and has the first ramp section 40.1. As described above, positive control is provided by the first ramp section 40.1 and the ramp track 42.1, which causes a rotation of the seat segment 50. Furthermore, a control bolt 22.1 is provided on the seat surface 22, which is guided on a control cam 50.1 of the seat segment 50 during rotation. The rotation of the seat segment 50 then causes the seat surface 22 to rotate away from the guide device 30. This increase in the seat surface inclination in the second position is in Fig. 5B is shown.

[0036] Likewise, in the Fig. 5A and Fig. 5B shows the optional coupling element 46, which, in conjunction with the optional backrest segment 52, provides a second forced control, thereby reducing the backrest inclination as in Fig. 4 is described.

[0037] Alternatively or additionally, it is also conceivable that a further embodiment could be based on the embodiment of Fig. 2 is based on the fact that, as described above, the backrest 24 is subject to forced control through the interaction of the second ramp section 40.2 on the backrest segment 52 and the ramp track 42.1 (not shown): Similar to Fig. In this arrangement, the backrest segment 52 is rotatably mounted relative to the backrest 24, has the second ramp section 40.2, and is subject to rotation by this positive control. A control bolt similar to the control bolt 22.1 can be provided on the backrest 24, which is guided on a control cam of the backrest segment 52 during rotation. The rotation of the backrest segment 52 then causes the backrest 24 to rotate towards the guide device 30. The optional coupling element 46 can again form a second positive control, which moves the seat surface 22 away from the guide device 30 while simultaneously increasing the inclination of the seat surface 22 (not shown).

[0038] In all embodiments, it is conceivable that the seat surface 22 and the rotatable seat segment 50, as well as the backrest 24 and the rotatable backrest segment 52, each have a common axis of rotation, as for example in Fig. 5 shown or have different axes of rotation (not shown).

[0039] To convert the movement of the vehicle seat 20 along the guide device 30 from the first position to the second position into an increase in the seat surface inclination and / or a decrease in the backrest inclination, the mechanical adjustment device 40 additionally or alternatively preferably comprises a Fig. 6 and Fig. Figure 7 shows a cam component 44 with a cam 44.1, wherein the cam 44.1 has a transmission angle α to the guide device 30.

[0040] Similar to the previous embodiments, in Fig. 5. The seat surface 22 is preferably rotatably mounted on the first axis of rotation D1. Preferably, a cam bolt 22.2 is arranged on the seat surface 22 for engagement with the cam 44.1. During the movement of the vehicle seat 20 along the guide device 30 from the first position to the second position, the cam bolt 22.2 is guided by the cam 44.1 such that, during this movement, the seat surface 22 is rotated away from the guide device 30 to increase the inclination, which in the Fig. 6A (first position) and 6B (second position) are shown. Thus, at least an increase in seat tilt similar to Fig. 1 will be provided.

[0041] As in the Fig. 6 and Fig. As shown in Figure 7, in all embodiments for transmitting a change in inclination, the adjusting device 40 comprises at least three gears 48, wherein the seat surface 22 and the backrest 24 are connected to the gears 48. For example, a first gear 48.1 can be attached to the seat surface 22. By increasing the inclination of the seat surface through the positive control of the adjusting device 40, for example by the ramp element 42 or as shown in the Fig. 6 and Fig. As shown in Figure 7, the first gear 48.1 rotates in a first direction through the cam component 44. A second gear 48.2 is engaged with the first gear 48.1 and is driven by it such that the second gear 48.2 rotates in a second direction opposite to the first. A third gear 48.3 is attached to the backrest 24 and is engaged with the second gear 48.2. The third gear 48.3 is driven by the second gear 48.2 such that the third gear 48.3 again rotates in the first direction opposite to the second. This provides a second forced control mechanism, through which, for example, an increase in the seat tilt is translated into a decrease in the backrest tilt.

[0042] Alternatively or additionally, the backrest 24 is preferably rotatably mounted on the first axis of rotation D2. Preferably, a cam bolt 22.2 is arranged on the backrest 24 for engagement with the cam 44.1 (not shown). During the movement of the vehicle seat 20 along the guide device 30 from the first position to the second position, the cam bolt 22.2 is guided by the cam 44.1 such that, during this movement, the backrest 24 is rotated towards the guide device 30 to reduce the inclination. Thus, at least one reduction in the backrest inclination can be achieved, similar to... Fig. 2 will be provided.

[0043] Alternatively or additionally, it is generally conceivable that the backrest 24 is subject to the positive control of the adjustment device 40, for example by the ramp element 42 and / or, as just described, by the cam component 44. The second positive control, by which, for example, the reduction of the backrest inclination is transferred to the increase of the seat surface inclination, is also provided in this case by the arrangement of the optional gears 48 and / or the optional coupling element 46: For example, at least three gears 48 and / or the coupling element 46 are conceivable for transferring the change in inclination from the backrest 24 to the seat surface 22.The gears 48 and / or the coupling element 46 can be attached to the seat surface 22, to the rigidly connected seat segment 50, to the rotatably mounted seat segment 50, to the rigidly connected backrest segment 52, to the rotatably mounted backrest segment 52 and / or to the backrest 24.

[0044] Alternatively or additionally, it is also conceivable that in the embodiments which have the ramp element 42, for example the Fig. 3, Fig. 4 to Fig. 5, at least three gears 48 are arranged for transmitting a change in inclination as described above. The gears 48 can replace or supplement the coupling element 46. The gears 48 can be attached to the seat surface 22, the rigidly connected seat segment 50, the rotatably mounted seat segment 50, the rigidly connected backrest segment 52, the rotatably mounted backrest segment 52 and / or the backrest 24.

[0045] In all embodiments, a greater number than three meshing gears 48 is also possible, with an odd number of meshing gears 48 being preferred. Likewise, different diameters of the gears 48 are conceivable for transmitting a change in inclination.

[0046] Furthermore, in the Fig. 6 and Fig. 7. It can be seen that the guide 44.1 can also run parallel to the guide device 30 in sections. This allows the vehicle seat 20 to be moved further along the guide device 30 without causing a change in the inclination of the seat surface 22 and / or the backrest 24.

[0047] Alternatively or additionally, all embodiments with a cam component 44 can again be provided with the coupling element 46, wherein the seat surface 22 and the backrest 24 are connected to the coupling element 46 to transmit a change in inclination, as exemplified in Fig. Figure 7 is shown. For simplicity, it shows Fig. 7 is only the first position.

[0048] Similar to the Fig. 3 or Fig. 4 The coupling element 46 can be attached to the seat surface 22 and the backrest 24 or to the seat segment 50 and the backrest segment 52, as for example in Fig. 7 shown should be attached.

[0049] In general, the following applies to all embodiments of the Fig. 1, Fig. 2, Fig. 3, Fig. 4 to Fig. 5. The designs of the first ramp section 40.1, the second ramp section 40.2, and the ramp track 42.1 are purely exemplary. Other forms are also conceivable to achieve a change in gradient.

[0050] Furthermore, in all embodiments, the transmission angle α can also be variable, for example along the X-direction. The following figures illustrate this point. Fig. 1, Fig. 3 and Fig. 4. Two different transmission angles α1 and α2. Additionally or alternatively, a plurality of different transmission angles α can also be used. n It is also conceivable that the transmission angle α is continuously variable, for example along the X-direction. Furthermore, in all embodiments, it is possible to arrange the cam component 44 and / or the ramp element 42 at a fixed position with respect to the guide device 30, preferably with respect to the base rail 32.

[0051] As already described, an existing seat 22 and / or backrest 24 can be equipped with the additional seat segment 50 and / or backrest segment 52 for guiding on the ramp track 42.1 or for connection with the coupling element 46 in order to achieve the above-described increase in seat inclination and / or decrease in backrest inclination.

[0052] In general, embodiments are also conceivable in which the adjusting device 40 comprises a ramp element 42 and a cam component 44, which together, as described above, effect a positive control for changing the inclination of the seat surface 22 and / or the backrest 24. Furthermore, it is also conceivable that the seat surface 22 and the backrest 24 are each subject to individual positive control by the adjusting device 40, for example by the ramp element 42 and / or the cam component 44. In this case, the coupling element 46 and / or the gears 48 can preferably be omitted.

[0053] Furthermore, it is conceivable that the adjusting device 40 comprises a plurality of first ramp sections 40.1, second ramp sections 40.2, ramp elements 42, ramp tracks 42.1, cam components 44, cams 44.1, coupling elements 46 and / or preferably parallel, interlocking gears 48 for a single vehicle seat 20. Likewise, a plurality of control bolts 22.1, cam bolts 22.2, floor rails 32, seat rails 34, seat segments 50 and / or backrest segments 52 in the vehicle seat arrangement 10 is conceivable.

[0054] In general terms, the first position can be understood as a sitting position and the second position as a lying position. What is not shown is a fixation of the seat surface 22 and / or the backrest 24 in the end positions, i.e., in the second position.

[0055] Finally, in all embodiments, the vehicle seat 20 can be moved from the second position back to the first position along the guide device 30, so that the seat surface inclination decreases again and / or the backrest inclination increases again.
