[0002] Seat part arrangement for a vehicle seat, vehicle seat, motor vehicle

[0003] The invention relates to a seat part arrangement for a vehicle seat, with at least one elastically deformable seat cushion and with at least one air cushion, in particular a massage device, which can be arranged or is arranged thereon.

[0004] Furthermore, the invention relates to a vehicle seat with such a seat part arrangement and to a motor vehicle with such a vehicle seat.

[0005] Seat part assemblies of the type mentioned above are known from the prior art. For example, patent EP 3 031 666 B1 discloses a cushion body assembly for a vehicle seat, comprising a cushion body with a seat cover material and / or with a cushioning material. The cushion body can be filled with a fluid or gas and arranged between the seat cover material and the cushioning material or between the cushioning material and a vehicle seat frame.

[0006] Also known are pneumatic lumbar support shield assemblies, which allow adjustment of the lumbar spine support (lordosis) for a user-specific, natural spinal contour in the lumbar region (S-shaped spine contour) by filling air cushions or air bladders that overlap, particularly in certain areas. The air supply is usually provided by a pump assembly. Control devices and valve assemblies regulate inflation, deflation, and maintenance of the air pressure.

[0007] The invention is based on the object of creating an improved seat part arrangement which ensures increased component protection for the air cushion(s) while maintaining at least the same seating comfort for a user of the vehicle seat.

[0008] The object underlying the invention is achieved by a seat part arrangement having the features of claim 1. According to the invention, the seat part arrangement has an elastically deformable, textile support element, that the air cushion can be arranged or is arranged between the support element and the seat cushion, and that the support element has a resilience that is at least as high as the resilience of the seat cushion. Such a support element creates a particularly advantageous solution for a seat part arrangement that is an alternative to the seat part arrangement mentioned at the outset, which, through the corresponding resilience of the support element and its arrangement, reliably ensures that the air cushion(s) are protected from damage when installed as intended. In particular, at least the support element and the air cushion(s) form an advantageous pre-assembly unit.The air cushion preferably has at least a substantially rectangular cross-section. In particular, two opposing outer edges of the air cushion extend in a meandering or undulating manner. The seat cushion in particular comprises an elastically deformable foam. Particularly preferably, at least the support element, in particular the seat part arrangement as a whole, is designed to be substantially mirror-symmetrical to its longitudinal central axis, at least with respect to its outer contour. Preferably, the air cushion is connectable or connected to a pneumatic pump arrangement via lines, wherein the pump arrangement in particular comprises a pump motor, for example arranged in a pump housing. Particularly preferably, the support element has a thickness of at most 5 mm, in particular of at most 2.5 mm. For example, the support element has a nominal thickness of 2 mm ± 0.5 mm.

[0009] According to a preferred embodiment of the invention, the support element comprises a felt, in particular, it is made of felt. Constructing the support element from or at least with a felt provides the advantage of reliably ensuring appropriate flexibility.

[0010] It is particularly preferred that the support element has a polyester content, in particular of at least 50%, preferably of 100%. Such a polyester content makes the support element particularly robust. The support element is preferably made of pure polyester (100% content), in particular a polyester felt.

[0011] According to a preferred development of the invention, the seat part arrangement comprises a seat frame, and the support element is or can be arranged on the seat frame. Such an arrangement results in the advantage that the air cushion(s) is or are reliably protected by the support element from damage caused by the seat frame. It is particularly preferably provided that the support element has at least one fastening point for the air cushion, for a seat frame and / or for a connecting line of the air cushion. Such a fastening point creates a particularly advantageous possibility for easily connecting the support element to at least one further component.

[0012] According to a preferred development of the invention, the fastening point has a fastening tab, in particular a punched-out fastening tab. The fastening tab thus forms a rear engagement element. Such a fastening tab offers the advantage that the fastening point has a particularly simple geometric design while still enabling a secure, positive connection to at least one other component. For example, the fastening tab is designed to be clamped into a seat base suspension of the seat frame.

[0013] Particularly preferably, the fastening point has a through-hole for the connecting cable and / or a fastening element, in particular a Christmas tree clip, rivet, and / or screw. Such a through-hole provides a particularly advantageous option for positively connecting the support element to at least one other component. For example, the through-hole is designed with the fastening element for attaching the support element to the seat frame.

[0014] According to a preferred embodiment of the invention, the through-hole is arranged within the fastening tab. This makes the fastening point particularly advantageous and space-saving.

[0015] Particularly preferably, the seat part arrangement comprises two air cushions arranged between the support element and the seat cushion. This provides a particularly advantageous possibility for the optimized planar arrangement of the air cushions on and / or on the support element and the seat cushion. The air cushions are preferably arranged at a distance from one another on the support element. Particularly preferably, the air cushions are each geometrically at least approximately identical. Preferably, the air cushions are mirror-symmetrical and / or aligned parallel to one another, in particular with respect to their respective longitudinal center axis.

[0016] According to a preferred development of the invention, the support element is at least substantially U-shaped, and each of the legs is assigned one of the two air cushions. Such a design of the support element offers the advantage that the air cushions are arranged at a mirror-symmetrical distance from one another. Preferably, the legs are each assigned to a longitudinal side of the seat cushion, so that, when installed as intended, the air cushions run to the left and right with respect to a longitudinal extension of the seat cushion.

[0017] It is particularly preferred that the support element, in particular between the two air cushions, has at least one recess for a fan assembly. This provides a particularly advantageous option for arranging the fan assembly.

[0018] The vehicle seat for a motor vehicle with the features of claim 12 is characterized by the seat part assembly according to the invention. This results in the aforementioned advantages. The same advantages arise when the vehicle seat is used in other means of transportation, in particular aircraft, as well as when the seat part assembly according to the invention is used in seats not installed in means of transportation, for example, massage seats.

[0019] The motor vehicle with the features of claim 13 is characterized by the vehicle seat according to the invention. This also results in the aforementioned advantages. In particular, the motor vehicle has the vehicle seat as the driver's seat.
