Method for producing a hybrid cushion element, in particular a seat and backrest cushion element for use in a motor vehicle, cushion element and vehicle seat having a cushion element
The invention relates to a hybrid cushion element, in particular a seat cushion element for use in a motor vehicle, to a method for producing a cushion element, and to a vehicle seat, wherein the cushion element has a non-woven fabric layer and a fiber composite material, wherein an insert material is arranged between the non-woven fabric layer and the fiber composite material. During the production in a mold, fibers for the fiber composite material wetted with a binder are applied to the insert material, wherein the insert material and the layer of fibers are then pressed to form a complex molded body, wherein the binder can be cured at a temperature less than 120° C.
1. A cushion element for use in a motor vehicle, the cushion element comprising a fleece layer, an elastic fiber composite material, and an inlay material arranged between the fleece layer and the elastic fiber composite material, wherein the elastic fiber composite material comprises a polyurethane-based or chloroprene-based binder curable at a temperature less than 120° C.;
wherein the elastic fiber composite material comprises tangled fibers wetted with the polyurethane-based or chloroprene-based binder, the polyurethane-based or chloroprene-based binder is curable by removing water without vulcanization, and the tangled fibers are spaced apart from one another by removing the water.
2. The cushion element as claimed in claim 1 , wherein the polyurethane-based or chloroprene-based binder is curable at a temperature less than 100° C.
3. The cushion element as claimed in claim 1 , wherein the inlay material has a lower specific weight than the elastic fiber composite material.
4. The cushion element as claimed in claim 1 , wherein the inlay material comprises a flatly arranged polyurethane material.
5. The cushion element as claimed in claim 1 , wherein the inlay material comprises a flatly arranged perforated polyurethane material.
6. The cushion element as claimed in claim 1 , wherein the inlay material comprises an activated carbon mat.
7. The cushion element as claimed in claim 1 , wherein the inlay material comprises an inflatable air cushion.
8. The cushion element as claimed in claim 1 , wherein the inlay material comprises a heating wire.
9. The cushion element as claimed in claim 1 , wherein the polyurethane-based or chloroprene-based binder is curable at a temperature less than 5° C.
10. A vehicle seat comprising a seat part and a backrest part, wherein the seat part and/or the backrest part comprises the cushion element as claimed in claim 1 .
11. The cushion element as claimed in claim 1 , wherein the polyurethane-based or chloroprene-based binder is curable at a temperature less than 80° C.
12. The cushion element as claimed in claim 1 , wherein the polyurethane-based or chloroprene-based binder is curable at a temperature less than 60° C.
13. The cushion element as claimed in claim 1 , wherein the polyurethane-based or chloroprene-based binder is curable at a temperature less than 40° C.
14. The cushion element as claimed in claim 1 , wherein the polyurethane-based or chloroprene-based binder is curable at a temperature less than 30° C.
15. The cushion element as claimed in claim 1 , wherein the polyurethane-based or chloroprene-based binder is curable at a temperature less than 25° C.
16. The cushion element as claimed in claim 1 , wherein the polyurethane-based or chloroprene-based binder is curable at a temperature less than 15° C.
