Definitions
- 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 that can be or is arranged thereon, in particular a massage device.
- the invention relates to a vehicle seat with such a seat part arrangement and to a motor vehicle with such a vehicle seat.
- a cushion body arrangement for a vehicle seat comprising a cushion body with a seat cover material and/or with a cushioning material, wherein the cushion body can be filled with a fluid or gas and can be arranged between the seat cover material and the cushioning material or between the cushioning material and a vehicle seat frame.
- pneumatic lumbar support shield arrangements that allow the lumbar spine support (lordosis) to be adjusted for a user-specific natural contour of the spine in the lumbar region (S-contour of the spine) by filling air cushions or air bubbles that overlap in particular in certain areas.
- the air supply is usually carried out by a pump arrangement. Filling, venting and maintaining the air pressure are controlled by control devices and valve arrangements.
- 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.
- 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 flexibility that is at least as high as the flexibility of the seat cushion.
- a support element creates a particularly advantageous alternative solution for a seat part arrangement to the seat part arrangement mentioned at the beginning, which reliably ensures, through the corresponding flexibility of the support element and its arrangement, that the air cushion(s) are protected from damage when installed as intended.
- at least the support element and the air cushion(s) form an advantageous pre-assembly unit.
- the air cushion has at least essentially a rectangular cross-section. In particular, two mutually opposite outer edges of the air cushion run in a meandering or wave-like manner.
- the seat cushion in particular has an elastically deformable foam.
- at least the support element, in particular the seat part arrangement as a whole, is designed to be essentially mirror-symmetrical to its longitudinal central axis, at least with respect to its outer contour.
- the air cushion is or can be connected to a pneumatic pump arrangement via lines, wherein the pump arrangement in particular has a pump motor arranged, for example, in a pump housing.
- the support element has a thickness of at most 5 mm, in particular of at most 2.5 mm.
- the support element has a nominal thickness of 2 mm ⁇ 0.5 mm.
- the support element has a felt, in particular is made of felt.
- 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.
- the seat part arrangement has a seat frame and that the support element can be arranged or is arranged on the seat frame.
- Such an arrangement has the advantage that the air cushion or cushions are safely protected by the support element from damage by the seat frame.
- 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.
- the fastening point has a fastening tab, in particular a free-cut fastening tab.
- the fastening tab forms a rear grip element.
- Such a fastening tab has the advantage that the fastening point has a particularly simple geometric design and yet a secure, positively locking connection to at least one other component is possible by means of a rear grip.
- the fastening tab is designed to be clamped into a seat base suspension of the seat frame.
- 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.
- a through hole creates a particularly advantageous possibility for positively connecting the support element to at least one other component.
- the through hole is designed with the fastening element for fastening the support element to the seat frame.
- the through hole is arranged within the fastening tab.
- the fastening point is designed to be particularly space-saving.
- the seat part arrangement has two air cushions that are arranged between the support element and the seat cushion. This creates a particularly advantageous possibility for the optimized flat arrangement of the air cushions on and/or on the support element and the seat cushion.
- the air cushions are preferably arranged on the support element at a distance from one another. It is particularly preferred that the air cushions are each geometrically designed to be at least approximately identical.
- the air cushions are preferably designed to be mirror-symmetrical and/or aligned parallel to one another, in particular with respect to their respective longitudinal center axis.
- the support element is at least substantially U-shaped, and that each of the legs one of the two air cushions is assigned.
- This type of design of the support element has the advantage that the air cushions are arranged at a mirror-symmetrical distance from one another.
- the legs are each assigned to a long side of the seat cushion, so that the air cushions run to the left and right in relation to a longitudinal extension of the seat cushion when installed as intended.
- the support element has at least one recess for a fan arrangement, in particular between the two air cushions. This creates a particularly advantageous possibility for arranging the fan arrangement.
- the vehicle seat for a motor vehicle with the features of claim 12 is characterized by the seat part arrangement according to the invention. This results in the advantages already mentioned. The same advantages result when the vehicle seat is used in other means of transport, in particular airplanes, and when the seat part arrangement according to the invention is used in seats not installed in means of transport, for example massage seats.
- the motor vehicle with the features of claim 13 is characterized by the vehicle seat according to the invention. This also results in the advantages already mentioned.
- the motor vehicle has the vehicle seat as a driver's seat.
- Figure 1 shows an advantageous seat part arrangement in an exploded view
- Figure 3 shows the seat part arrangement in a plan view
- Figure 4 shows a support element of the seat part arrangement in a plan view.
- Figure 1 shows an advantageous seat part arrangement 1 for a vehicle seat 2 in an exploded view.
- the vehicle seat 2 has in particular a backrest (not shown).
- the seat part arrangement 1 has an elastically deformable, for example a seat cushion 3 comprising foam.
- the seat part arrangement 1 also has two air cushions 4 which can be arranged or are arranged on the seat cushion.
- the air cushions 4 are in particular part of a massage device and can be connected or are connected in terms of lines to a pump arrangement (not shown).
- the seat part arrangement 1 further comprises an elastically deformable, textile support element 5.
- the air cushions 4 can be arranged or are arranged between the support element 5 and the seat cushion 3.
- the support element 5 has a flexibility that is at least as great as the flexibility of the seat cushion 3.
- the support element 3 also comprises a felt and/or a polyester component, in particular it is made entirely from a polyester felt.
- the seat part arrangement 1 also has a seat frame 6.
- the support element 5 can be arranged or is arranged on the seat frame 6.
