Abstract

The invention relates to the upholstery of a seat element for a motor vehicle and to the method of creating it, in which method a foam support block is produced to fit a frame element; a cover element is created by cold-forming a foam sprayed onto a polypropylene substrate and attached on the reverse side of a textile material in the form of a skin or synthetic material to define the visible shape of the seat element; and the cover element is attached to the support block.

Claims

1. A method for forming upholstery for an element of a motor vehicle seat, the method comprising:

producing a foam support block configured to fit a frame element;

spraying foam on a polypropylene substrate to form a coated substrate;

attaching the coated substrate to a reverse side of a textile material in a press comprising a die and punch to provide a cover element, wherein the textile material is in the form of skin or of a synthetic material, and wherein the press imparts in the cover element a visible shape of the element; and

attaching the cover element is to the support block external to the press.

2. The method of claim 1, wherein the cover element is attached to the support block by self-adhesive bands.

3. The method of claim 1, wherein the cover element is attached to the support block by clips received in adapted guide strips overmolded in the support block.

4. The method of claim 1, wherein the textile material in the form of skin or of a synthetic material of the cover element at least partially covers the support block.

5. The method of claim 1, wherein the cover element comprises foams having different densities and/or hardnesses.

6. The method of claim 1, wherein attaching the coated substrate to the textile material in the press further comprises applying the press a while the foam is in a viscous state.
