Seat element, in particular, headrest of a vehicle seat
The present disclosure relates to a seat element, in particular, a headrest for a vehicle seat, the seat element comprising at least one support bar made of metal, a first layer provided at an exterior surface of the support bar, and a cushion made of an upholstery material. Hereby, the first layer is formed by blowing on first fibers made of plastics which are thermally welded directly or indirectly to the exterior surface. At least part of the first fibers extends away from the exterior surface and/or the first layer towards the outside into the upholstery material and is thermally cross-linked with the upholstery material, in particular, blown-on further fibers.
1. A seat element for a vehicle seat, the seat element comprising:
at least one support bar made of metal,
a first layer provided at an exterior surface of the at least one support bar, and
a cushion made of an upholstery material attached to the at least one support bar,
wherein the first layer comprises first fibers made of a plastic material which are attached directly at the exterior surface, wherein first ends of the first fibers are attached directly to the exterior surface and second ends of the first fibers extend into the upholstery material of the cushion and
wherein the first fibers sticking out from the exterior surface and/or the first layer are thermally received or thermally cross-linked in the upholstery material.
2. The seat element of claim 1 , wherein the seat element is a headrest for a vehicle seat.
3. The seat element of claim 1 , wherein the first fibers are welded onto the exterior surface of the at least one support bar thereby forming the first layer.
4. The seat element of claim 3 , wherein the first fibers are welded onto the exterior surface by being blown onto the exterior surface under heat and pressure.
5. The seat element of claim 1 , wherein the upholstery material comprises further fibers which are welded to one another and to the first fibers.
6. The seat element of claim 5 , wherein the first fibers and the further fibers are identical.
7. The seat element of claim 1 , wherein the upholstery material comprises one or more filler materials from a group consisting of powdery fillers, granular fillers, and foamy fillers.
8. The seat element of claim 7 , wherein the at least one filler material is made from recycled plastic material.
9. The seat element of claim 1 , wherein the first layer formed at the exterior surface of the at least one support bar is formed exclusively from thermally welded-on first fibers, the first fibers comprising the plastic material, at least at their exterior surface.
10. The seat element of claim 9 , wherein the fibers are formed as single-component fibers made of at least one material from a group consisting of thermally softening plastics, thermoplastic plastics, dual-component fibers having an exterior layer made from thermally softening plastics.
11. The seat element of claim 1 , wherein a grid made of plastics or metal is arranged around the exterior surface, and the first fibers are welded onto the exterior surface and onto the grid.
12. The seat element of claim 1 , wherein an adhesive layer is applied onto the exterior surface in total or in part.
13. The seat element of claim 1 , wherein the seat element comprises two headrest bars, one of which is the at least one support bar, and a middle section connecting the two headrest bars.
14. The seat element of claim 13 , wherein the headrest bars and the middle section are parts of a U-shaped bracket.
