Abstract

A cover element for a motor vehicle seat element lining, including: a foam on the reverse side of a textile, skin, or synthetic material; and in edges, intended to be assembled by sewing to at least one piece of textile, skin, or synthetic material, one or a plurality of embossed notches forming alignment marks to perform the sewing.

Claims

1. A cover element for a motor vehicle seat element lining, comprising:

a foam on a reverse side of a textile, skin, or synthetic material; and

in edges, intended to be assembled by sewing to at least one piece of textile, skin, or synthetic material, one or a plurality of embossed notches forming alignment marks with the at least one piece of textile, skin, or synthetic material.

2. The cover element of claim 1, wherein the embossed notches are recessed with respect to a side of the foam.

3. A motor vehicle seat element comprising the cover element of claim 2.

4. A motor vehicle seat comprising the seat element of claim 3.

5. The cover element of claim 1, wherein the embossed notches are raised in a direction of the least one piece of textile, skin, or synthetic material.

6. A motor vehicle seat element comprising the cover element of claim 5.

7. A motor vehicle seat comprising the seat element of claim 6.

8. The cover element of claim 1, obtained by cold forming of a foam sprayed on a substrate and arranged on the reverse side of said textile, skin, or synthetic material.

9. A motor vehicle seat element comprising the cover element of claim 8.

10. A motor vehicle seat comprising the seat element of claim 9.

11. A motor vehicle seat element comprising the cover element of claim 1.

12. A motor vehicle seat comprising the seat element of claim 11.

13. A method of forming marks of alignment of an edge of a cover element comprising a foam on a reverse side of a textile, skin, or synthetic material, with at least one piece of textile, skin, or synthetic material, comprising a step of forming, by molding, embossed notches in said edge, the notches forming the marks of alignment.

14. The method of claim 13, wherein said cover element is formed in a mold defining a shape of the foam, and wherein notches or strips are arranged in the mold and define said embossed notches in the foam.

15. The method of claim 13, wherein said embossed notches are formed at intervals in the range from a few centimeters to a few tens of centimeters in the periphery of the cover element.
