Description

Technical Field

[0001] The present invention relates to a seating component device for a vehicle seat, having at least one elastically deformable seat cushion and at least one air cushion, particularly a massage device, that can be arranged or has been arranged thereon.

[0002] The present invention also relates to a vehicle seat having such a seating component device and a motor vehicle having such a vehicle seat. Background Technology

[0003] The type of seating component device mentioned at the beginning is known in the prior art. For example, a cushion body device for a vehicle seat is known from patent EP 3 031666 B1, comprising a cushion body having a seat cover material and / or a cushion material, the cushion body may be filled with fluid or gas and located between the seat cover material and the cushion material or may be arranged between the cushion material and the vehicle seat frame.

[0004] Pneumatic lumbar support devices are also known, which can adjust lumbar support (spine lordosis) by filling air cushions or bubbles to adapt to the user-specific natural contour of the spine in the lumbar region (the S-curve of the spine), especially covering certain areas. Air supply is typically provided by a pump device. Inflation, deflation, and air pressure maintenance are controlled by control and valve devices. Summary of the Invention

[0005] Summary of the Invention The objective of this invention is to create an improved seating component device that ensures enhanced component protection for the air cushion while maintaining at least the same level of seating comfort for users of vehicle seats.

[0006] The objective of this invention is achieved through a seating component device having the features of claim 1. According to the invention, the seating component device has an elastically deformable fabric support element, an air cushion that can be or has been arranged between the support element and the seat cushion, and the support element has a flexibility at least as high as that of the seat cushion. As a result, such a support element creates a particularly advantageous solution for the seating component device, an alternative to the aforementioned device, which reliably ensures that the air cushion is protected from damage during intended installation through the appropriate flexibility of the support element and its arrangement. In particular, at least the support element and one or more air cushions form an advantageous pre-assembled unit. The air cushion preferably has at least a substantially rectangular cross-section. Specifically, the two opposing outer wings of the air cushion extend in a meandering or wavy shape. The seat cushion particularly has an elastically deformable foam. Particularly preferably, at least the support element, and especially the seating component device as a whole, is designed to be substantially mirror-symmetric with respect to its longitudinal central axis, at least with respect to its outer contour. Preferably, the air cushion is technically connected to or has been connected to a pneumatic pump assembly, wherein the pump assembly particularly has, for example, a pump motor arranged in a pump housing. Particularly preferred is that the support element has a thickness / wall thickness of up to 5 mm, especially up to 2.5 mm. For example, the support element has a nominal thickness of 2 mm ± 0.5 mm.

[0007] According to a preferred improvement of the invention, the support element has a felt material, particularly made of felt. Forming the support element from felt, or at least from felt, has the advantage of reliably ensuring appropriate flexibility.

[0008] Particularly preferred is that the support element has a polyester content, especially at least 50%, and preferably 100% polyester content. This polyester content makes the support element particularly robust. The support element is preferably made of pure polyester (100% content), especially polyester felt.

[0009] According to a preferred embodiment of the invention, the seating component assembly has a seat frame, and a support element can be arranged or is already arranged on the seat frame. The advantage of this arrangement is that the support element reliably protects one or more air cushions from damage to the seat frame.

[0010] Particularly preferably, the support element has at least one fastening point for the air cushion, for the seat frame, and / or for the connecting wires of the air cushion. This fastening point creates a particularly advantageous possibility for easily connecting the support element to at least one other component.

[0011] According to a preferred improvement of the invention, the fastening point has a fastening tab, particularly a punched fastening tab. The fastening tab forms a hook element. The advantage of this fastening tab is that the fastening point is particularly simple in geometry and can still be securely connected to at least one other component by means of the hook. For example, the fastening tab is designed to snap into the seat base of a seat frame.

[0012] Particularly preferably, the fastening point has through holes for connecting wires and / or fastening elements, particularly tree-shaped clips, rivets, and / or screws. Such through holes create a particularly advantageous possibility for forcibly connecting the support element to at least one other component. For example, the through holes are formed with fastening elements for securing the support element to the seat frame.

[0013] According to a preferred improvement of the invention, the through holes are arranged within the fastening plate. As a result, the fastening points are designed to save space in a particularly advantageous way.

[0014] Particularly preferably, the seating assembly includes two air cushions arranged between the support element and the seat cushion. This provides a particularly advantageous option for an optimized, flat arrangement of the air cushions on the support element and / or seat cushion. The air cushions are preferably arranged on the support element at a distance from each other. Particularly preferably, the air cushions are at least substantially identical in geometry. Preferably, the air cushions are designed to be mirror-symmetrical, especially relative to their respective longitudinal central axes, and / or aligned parallel to each other.

[0015] According to a preferred improvement of the invention, the support element is at least substantially U-shaped, and one of the two air cushions is assigned to each side segment. This design of the support element has the advantage that the air cushions are arranged in a mirror-symmetric manner. Preferably, each side segment is assigned to the long side of the seat cushion such that, when installed as intended, the air cushion extends to the left and right relative to the longitudinal extent of the seat cushion.

[0016] Particularly preferably, the support element, especially between the two air cushions, has at least one recess for the fan assembly. This creates a particularly advantageous option for arranging the fan assembly.

[0017] The vehicle seat for motor vehicles having the features of claim 12 is characterized by the seating component device according to the invention. This leads to the advantages already mentioned. The same advantages arise when the vehicle seat is used in other means of transport, especially aircraft, and when the seating component device according to the invention is used in seats not installed in a vehicle (e.g., massage seats).

[0018] The motor vehicle having the features of claim 13 is characterized by a vehicle seat according to the invention. This also leads to the advantages already mentioned. In particular, the motor vehicle has a vehicle seat that serves as a driver's seat. Attached Figure Description
