Description
Technical Field
The present invention relates to a lateral support for a seat cushion structure of a vehicle seat and a seat cushion structure for a vehicle seat, the seat cushion structure having the lateral support. The invention also relates to a vehicle seat for a vehicle having the seat cushion structure, and to a vehicle having the vehicle seat.
Background
Vehicle seats typically have a seat cushion with an internally located support structure. The support structure is generally configured for securing padding and other components, such as for height adjustment of the seat cushion and for attaching the backrest. The aim of constructing a support structure that meets the required profile for tension, compression and thrust is known.
For example, document DE 10 2013 214 789 A1 describes a vehicle seat structure made of an inner lining and a fiber structure fixed to the inner lining. The vehicle seat structure has a closed loop structure and can be used in this configuration for a seat unit of a vehicle seat. The ring structure can have an interface for fastening further components.
Disclosure of Invention
The present invention is based on the task of providing a seat cushion structure for a vehicle seat which is improved in terms of safety. This object is achieved by a transverse support for a seat cushion structure of a vehicle seat with the features of claim 1, by a seat cushion structure according to claim 9 for a vehicle seat with transverse support, by a vehicle seat according to claim 12 for a vehicle with the seat cushion structure and by a vehicle according to claim 15 with a vehicle seat. The dependent claims, the subsequent description and/or the accompanying drawings lead to preferred or advantageous embodiments of the invention.
A lateral support for a seat cushion structure of a vehicle seat is proposed. The transverse support is made of metal, in particular steel pipe. The transverse support structure and/or the arrangement serves to form a transverse connection between the left-hand longitudinal support and the right-hand longitudinal support of the seat cushion structure in the rear, in particular with respect to the seating direction of the vehicle seat. In particular, the lateral support is a rear lateral support of the seat cushion structure.
The vehicle seat preferably relates to a front row seat of the vehicle, in particular to a driver seat or a co-driver seat. The driver's seat can be arranged on the left side of the vehicle or on the right side of the vehicle, as is the case in particular in right-hand driver's seats. Preferably, the vehicle seat comprises a backrest structure for a backrest of the vehicle seat, wherein optionally a side airbag for protecting a passenger sitting on the vehicle seat is arranged on the backrest structure.
The transverse support has at least one damping device. The weakening device forms at least one set bending position in which the transverse support can be deformed and/or deformed specifically when and/or during lateral forces act on the seat structure and in particular on the vehicle seat. In particular, the lateral support can be bent when and/or during the occurrence of a lateral force. The lateral force action on the seat cushion structure can be triggered, for example, by a side collision of the vehicle, in particular by a collision towards the door corresponding to the vehicle seat and/or towards the lower boundary of the door (so-called door sill or door sill).
In one possible embodiment of the invention, at least one damping device is arranged in the middle or middle region of the transverse support. The middle region is arranged, for example, in the middle third of the longitudinal extension of the transverse support. The weakening means in the middle region and/or in the middle of the rear transverse support have the following advantages: in the event of lateral forces acting on the seat cushion structure, a targeted deformation of the rear transverse support can be achieved there precisely. The transverse support can be bent in the middle or in the middle region when and/or during the application of a lateral force to the vehicle seat. In an advantageous manner, strong deformations of the lateral support in the vicinity of and/or in the attachment location on the longitudinal support, which is subjected to lateral forces, can be prevented. Thus, bending or breakage in at least one of the attachment locations can be avoided, as is often the case in conventional seat cushion structures. Such bending or breaking at the attachment point generally results in a strong and abrupt deformation of the seat cushion structure and thus of the vehicle seat (e.g. due to tilting and/or lowering of the seat cushion structure). This can have the disadvantageous consequence of a impairment of the functional capacity of the side airbag arranged on the backrest structure.
The arrangement of the weakening device according to the invention and the bending ensured thereby in the middle or middle region of the transverse support advantageously enables an improvement in the functional capability of the side airbag integrated in the vehicle seat. In particular, the centering of the damping device can advantageously influence safety considerations, in particular the reliable opening and/or positioning of the side airbag.
In a possible embodiment of the invention, the at least one weakening means is configured as at least one recess in the lateral support. For example, the cavity has a spherical cross-section. Alternatively, the at least one weakening means can be configured as at least one cut-out in the lateral support. Preferably, the cutouts are oriented in the same direction, in particular parallel or orthogonal to the longitudinal extension of the lateral support.
In a further possible embodiment of the invention, the at least one weakening means is configured as at least one recess in the lateral support. For example, the recess can be a hole or cut in the lateral support. Preferably, the hole has a round, in particular circular, cross section. Optionally, the cutting openings are oriented in alignment in the same direction, in particular parallel or orthogonal to the longitudinal extension of the transversal support.
Alternatively, it is possible within the framework of the invention for the at least one weakening device to be configured as a laterally supported cross-sectional area which is altered in any way by at least one indentation, embossing and/or crimping. Preferably, the torsion springs of the height adjustment means of the seat cushion structure can be integrated in the lateral support. In particular, the torsion spring can be integrated in the middle or middle region of the transverse support, wherein the torsion spring can be positively fixed there by means of a retraction, embossing and/or crimping.
A seat cushion structure for a vehicle seat with a transverse support according to the description so far and/or according to any one of claims 1 to 8 constitutes a further subject matter of the invention. Preferably, the seat cushion structure is configured for constituting a seat cushion of a vehicle seat. For this purpose, the seat cushion can be fastened to the seat cushion structure, for example. In particular, the seat cushion structure is configured to carry a seat cushion.
In one possible configuration of the invention, the seating pad structure includes a left longitudinal support and a right longitudinal support. For example, the left-hand longitudinal support is configured as a longitudinal support of the door side and/or is arranged at the door side, in particular when the seat cushion structure is integrated into the vehicle seat on the left side. In a right-hand drive vehicle, the seat cushion structure is preferably constructed in a mirror-symmetrical manner, wherein the right-hand longitudinal support is arranged in this case on the door side. Preferably, the transverse support is attached indirectly or directly, for example form-and/or force-locking, to the left and to the right longitudinal support. In particular, the transverse support is fastened in the rear third, in particular on the rear end of the longitudinal support.
In one possible implementation of the invention, the seat cushion structure includes a height adjustment device. Preferably, the height adjustment means is configured for adjusting in height the longitudinal support, the rear transverse support and (optionally supplementary) the front transverse support of the seat cushion structure. Thus, it is possible for a passenger sitting on the vehicle seat to adjust the seat height of the seat cushion to match his/her height. The height adjustment means comprise, for example, a gear or rack drive and at least one swingable lever, for example, a swingable front lever and a swingable rear lever for transmitting force to the longitudinal support and/or the transverse support. The rear transverse support can be attached to the left and right transverse supports, for example, by means of a height adjustment device, in particular by means of the rear transverse support. For example, the attachment location of the rear lateral support is arranged on a swingable rear lever.
In an alternative embodiment of the invention, the height adjustment device has a torsion spring. The torsion spring preferably extends through the ground in sections via a rear transverse support. The torsion spring is preferably held in a form-locking manner, in particular by means of a setback and/or embossing and/or crimping, in the middle or middle region of the transverse support. In particular, one of the ends of the torsion spring comes out of the rear transverse support, wherein said end is hooked into one of the longitudinal supports, in particular into the hole in the longitudinal support corresponding thereto. The other end of the torsion spring is preferably secured inside the cross tube by means of indenting, embossing and/or crimping. The torsion spring is preferably provided for bringing the adjustment forces required for the upward and downward height adjustment, respectively, close to each other. In particular, the torsion spring is constructed and arranged to reduce and/or prevent possible free play in the overall system of the height-adjustable seat cushion structure by pretensioning thereof.
A vehicle seat for a vehicle constitutes a further subject matter of the invention. A vehicle seat comprising a seat cushion structure according to the description so far and/or according to any one of claims 9 to 11.
The vehicle seat comprises a backrest structure, to which backrest padding, for example for constituting a backrest of the vehicle seat, can be fastened. In particular, the backrest structure is configured to carry a backrest cushion. Preferably, the backrest structure is connected to the seat cushion structure in at least two attachment positions in a movable, in particular pivotable, manner.
In a preferred embodiment of the invention, the vehicle seat comprises a side airbag. Preferably, the side airbag is arranged on the backrest structure. Preferably, the side airbag includes a gas generator for generating and releasing gas and an inflatable gas bag. The side airbag can be activated during a vehicle crash, for example a side crash, and/or during a side force acting on the vehicle seat, so that the gas generator generates gas and introduces it into the gas bag in order to expand it explosively.
Pulling out of the attachment location occurs when lateral forces are applied to the conventional seat cushion structure. This can lead to functional restrictions due to the modified opening and/or positioning of the gas bag, which can be disadvantageous in terms of safety technology. For example, it may happen that: if the backrest structure occupies a changed position in the vehicle due to a strong deformation and/or lowering of the seat cushion structure, the gas bag is hindered from opening fast enough or cannot be opened towards the correct direction and/or towards the final position in which it is arranged.
Since the at least one damping device is arranged in the middle or middle region of the transverse support and preferably forms a set bending position there, the seat cushion structure and/or the seat cushion can be bent there in a targeted manner when a lateral force acts on the vehicle seat. Thus, the acting force can be derived from the attachment point. In this way, functional restrictions due to the modified opening and/or positioning of the gas bag and the resulting safety restrictions can be prevented in an advantageous manner.
In a further preferred embodiment of the invention, the vehicle seat is configured as a front seat of a vehicle. The front row seat can be arranged and/or configured as a driver seat on the driver side of the vehicle or as a passenger seat on the passenger side of the vehicle.
A vehicle with a vehicle seat according to the description so far and/or according to any of claims 12 to 14 constitutes a further subject matter of the invention. For example, the vehicle is in the form of a passenger car or a commercial vehicle.

Detailed Description
Fig. 1 shows a side view of a vehicle seat 50 for a vehicle, in particular for a passenger car or for a commercial vehicle. The vehicle seat 50 is configured as a front seat of a vehicle, in particular a driver seat or a passenger seat. Alternatively, the vehicle seat can be configured as a seat of a rear seat row of a vehicle. The vehicle seat 50 defines a seating direction 56 for a passenger of the vehicle, which passenger is able to sit on the vehicle seat 50 when the vehicle seat is integrated into the vehicle.
The vehicle seat 50 includes a seat cushion 51, a backrest 52, and a headrest 65. The seat cushion 51 includes a seat cushion structure 10 (which is more accurately shown in fig. 2) and a cushion 55 carried by the seat cushion structure 10. The backrest 52 comprises a backrest structure 53 and a backrest cushion 54 carried by the backrest structure 53. The backrest structure 53 is swingably attached to the seat cushion structure 10 by a swinging means 63 which is arbitrarily constructed and shown by a region marked with a broken line.
The vehicle seat 50 has a seat lower structure 57 anchored in a vehicle floor 64. The seat cushion structure 10 is movably disposed on the seat lower structure 57. The vehicle seat 50 includes a side airbag 58 having a gas generator for generating and releasing gas and having an air bag inflatable by the gas. The side airbag 58, in particular the gas generator, is fastened to the backrest structure 53 of the backrest 52. In the event of a vehicle side impact, for example, a crash into a pillar, tree or the like, a side force action 19 (see fig. 6) occurs on the vehicle seat 50 in a transverse direction 59 oriented transversely to the seating direction 56. The side airbag 58 can be activated due to the side force action 19. In a state in which the side airbag 58 is activated, gas is generated and introduced into the air bag so that the air bag explosively expands between the door corresponding to the vehicle seat 50 and/or the B pillar of the vehicle and the occupant seated in the vehicle seat to prevent the upper body of the occupant from striking the door and/or the B pillar.
The seat cushion structure 10 is shown in fig. 2 in a top perspective view. The seat cushion structure 10 is movably connected with the seat lower structure 57. The seat lower structure 57 comprises two guide rails 60a,60b along which the seat cushion structure 10 can slide and/or move towards and against the seating direction 56 by means of two rear guide elements 61a,61b and by means of two front guide elements 61c,61 d.
The seat cushion structure 10 includes a rear lateral support 1, a left longitudinal support 2, a right longitudinal support 3, and a front lateral support 4. The rear transverse support 1 constitutes a rear transverse connection of the left-hand longitudinal support 2 and the right-hand longitudinal support 3 in the seat cushion structure 10 arranged opposite to the seating direction 56. The front transverse support 4 constitutes a front transverse connection of the two longitudinal supports 2, 3.
The seat cushion structure 10 comprises a height adjustment device 11 by means of which height adjustment device 11 the transverse supports 1,4 and the longitudinal supports 2,3 and thus the seat cushion 51 (fig. 1) can be adjusted in height relative to the seat substructure 57. The height adjustment device 11 has a gear-pendulum transmission 12 for transmitting force. The gear swing transmission 12 is arranged on the left longitudinal support 2. It comprises two pivotally interconnected pivot levers 13a,13b, of which a first pivot lever 13a is pivotally connected to the left longitudinal support 2 and a second pivot lever 13b is pivotally connected to the left rear guide element 61 b. Alternatively, the height adjustment device 11 can also be implemented in other mechanical ways, or for example electrically or pneumatically.
The height adjustment device 11 comprises three further individual levers 14a,14b,14c, wherein the first individual lever 14a is rotatably connected to the right rear guide element 61a, wherein the two further individual levers 14b,14c are pivotably connected to the front guide elements 61c,61 d.
The rear transverse support 1 is fixed in a first attachment point 5 on a first single rod 14a and in a second attachment point 6 on a second oscillating rod 13b in a form-locking and/or force-locking manner, for example welded and/or spliced thereto, whereby the rear transverse support 1 is connected to the left and right longitudinal supports 2,3 via the first single rod 14a and the second single rod 13 b. In a corresponding manner, the front transverse support 4 is fixed with two further single bars 14b,14c in two attachment points 7,8 and is connected with the left and right longitudinal supports 2,3 by means of them.
The height adjustment device 11 includes a torsion spring 21 for supporting the height adjustment. The torsion spring 21 is arranged inside the rear transverse support 1 and extends in sections through the rear transverse support, wherein it is fastened on the end side to the left longitudinal support 2. The torsion spring 21 is centrally set in the rear transverse support 1 by means of retraction, embossing and/or crimping and is preloaded by torsion.
The rear transverse support 1 has at least one weakening device 9. The weakening means 9 are arranged in the middle region of the rear transverse support 1, for example in the middle third in relation to the longitudinal extension of the rear transverse support 1 and/or in the middle of the rear transverse support 1. The weakening device 9 constitutes a set bending position 15 in the rear transverse support 1.
The seat cushion structure 10 is shown in top plan view from above in fig. 6. The rear transverse support 1 can be folded in the set folding position 15 when and/or during the application of a lateral force 19 to the vehicle seat 50 and thus also to the seat cushion structure 10. In particular, the weakening means 9 ensure a purposeful deformation in the middle region and/or in the middle of the rear transverse support 1 (see fig. 8).
The torsion spring 21 is arranged in the rear transverse support 1 adjacent to the attachment point 6 on the left longitudinal support 2. The torsion spring 21 is fixed there in the rear transverse support 1 by means of a setback and/or embossing and/or crimping 20.
In fig. 7, a conventional and non-according to the invention seat cushion structure 40 is shown in a top view from above. The conventional seating pad structure 40 includes a rear lateral support 41 without the attenuation device 9 in the middle or in the middle region. The rear transverse strut 41 has the weakest cross-section in the region of the setback and/or embossing and/or crimping press 20. This can lead to the rear transverse support 41 being strongly deformed in the region of the weakest cross section in the event of a lateral force action 19 and thus adjacent to the attachment point 6, and thus to the rear transverse support 41 being pulled out of the attachment point 6 and the rear transverse support 41 being detached from the left longitudinal support 2. The extraction causes the seating structure 40 to become unstable, the left longitudinal support 2 to tilt significantly, and the backrest structure 53 of the backrest 52 attached to the longitudinal supports 2,3 to thereby change in its initial position and/or orientation. Such changes in the position and/or orientation of the backrest 52 may adversely affect the safety-related function of the side airbag 58. In particular, a changing opening direction and/or positioning of the air bag and a resulting suspension of the air bag, for example, can result, which can lead to a reduction in the protection of the passengers.
Fig. 8 shows, in a top view from above, a seat cushion structure 10 according to the invention after the lateral force action 19 of fig. 6 has taken place, which seat cushion structure has a rear transverse support 1 (which has a damping device 9).
The weakening means 9 arranged in the middle region and/or in the middle of the rear longitudinal support 1 as a set bending position 15 ensures a purposeful deformation of the rear transverse support 1, so that said rear transverse support is bent in the set bending position 15. The strong deformation adjacent to the attachment position 6 and the extraction of the rear lateral support 10 as in the conventional seat cushion structure 40 of fig. 7 can thereby be avoided. Furthermore, by setting the arrangement of the breaking point 15 in the middle region and/or in the middle of the rear longitudinal support 1, the following angles can be reduced: in the event of a lateral force action 19, the left longitudinal support 2 is inclined at said angle, so that the inclined position can be reduced compared to the left longitudinal support 2 of the conventional seat cushion structure 40. The change in position and/or orientation of the backrest 52 attached to the longitudinal supports 2,3 can thereby be reduced or even avoided. In particular, the functional capability of the side airbag 58 for protecting the occupant in the event of a side collision of the vehicle can be maintained.
In fig. 3a, the rear transverse support 1 is shown in a top perspective view and in a cross section in the region of the damping device 9. Fig. 3b shows the transverse support 1 in a further cross-sectional view through the weakening device 9. The weakening means 9 are realized as deformations in the rear transverse support 1, wherein they are designed as cavities 16. The cavity 16 has a spherical cross-section. In an alternative embodiment, the weakening device 9 can be configured as a cutout oriented perpendicular to the longitudinal extension of the rear transverse support 1.
Fig. 4 and 5 show the rear transverse support 1 in a further perspective top view and in a corresponding cross section in the region of the damping device 9. The weakening means 9 are configured as recesses in the rear transverse support 1. According to fig. 4, the weakening device 9 is configured as a cut 17 extending perpendicularly to the longitudinal extension of the rear transverse support 1. Fig. 5 shows the weakening device 9 as a circular hole 18 in the rear transverse support 1.
The weakening means 9 can alternatively be realized by means of a setback, embossing and/or crimping 20, by means of which the torsion spring 21 is fixed inside the rear transverse support 1. In this case, the torsion spring 21 is positioned in the middle region and/or in the middle of the rear transverse support 1 and is fixed there by means of the setback, embossing and/or crimping 20. This has the following advantages: the indentation, embossing and/or crimping 20 forms the weakening device 9 and the setting bending position 15 in the rear longitudinal support 1 and thus makes it possible to dispense with the introduction of a separate or additional weakening device 9.
At least one embodiment has been disclosed in detail above, however, it is to be recognized that: there are a number of variants according to the invention. Likewise, it is acknowledged that: at least one embodiment is merely exemplary in nature and is not intended to limit the scope, applicability, or configuration of the invention. Rather, the present disclosure is to be construed as a suitable route pattern for putting at least one embodiment into practice. Thus, it should be acknowledged that: various modifications can be made in the function or arrangement of elements of at least one embodiment without departing from the scope as set forth in the claims and their legal equivalents.
