Abstract

The cover comprises a panel, a skirt (6) and a margin (7) that extend mutually one from the other and that are designed respectively to cover the top of the cushion, at least a major fraction of its flanks (3b), and a corresponding marginal band around its bottom (3c), at least the major fraction of the length of the free edge of the margin (7) being pleated and tensioned by being sewn (at 14) in a prefolded state to a non-stretch cord that extends without folds along said edge.

Claims

1. A cover for covering a cushion of a motor vehicle seat, the cushion comprising a top, flanks and a bottom, said cover comprising:

a panel having an outer edge for covering the top of the cushion;

a skirt for covering the flanks of the cushion, said skirt having a top edge joined to said outer edge of said panel and having a bottom edge;

a margin having pleats therein, formed along the bottom edge of said skirt; and

a non-stretch cord positioned on one side of said pleated margin at an edge thereof and fastened to said previously pleated margin by stitching for holding the margin against the bottom of the cushion.

2. A cover according to claim 1 wherein the pleats are distributed along the margin at a density that varies locally so as to increase with increasing local curvature of the edge of the margin.

3. A cover according to claim 1 wherein said skirt includes an opening of sufficient size to enable said cover to be placed on the cushion.

4. A cover according to claim 1 wherein said non-stretch cord extends beyond a pleated edge of the margin for attachment to at least a portion of the joined edges of the skirt and the panel.

5. A cover according to claim 1 wherein the skirt includes an apron extending from the outer edge of said panel, said apron having a substantially rectilinear free edge for folding down over the bottom of the cushion when said cover is in place on the cushion, said apron including means for fastening to the bottom of the cushion.

6. A cover according to claim 5 wherein said cushion comprises a front flank, a rear flank and two side flanks, said apron covering the rear flank of said cushion.

7. A cover according to claim 5 further comprising flaps attached to said skirt between the top and bottom edges for ensuring that rear ends of said side flanks are completely covered.

8. A cover according to claim 1 wherein said non-stretch cord comprises a braid.

9. A method of covering a cushion for a motor vehicle seat, said cushion comprising a top, flanks and a bottom, said method comprising the steps of:

constructing a cover comprising a panel and a skirt having a margin at a bottom edge;

forming pleats in said margin;

positioning a non-stretch cord on one side of said pleated margin;

fastening the pleated margin to said non-stretch cord by stitching;

attaching a top edge of said skirt to outer edges of said panel; and

installing the cover on the cushion such that the panel covers the top of the cushion, the skirt covers the flanks of the cushion and the non-stretch cord holds the margin against the bottom of the cushion.

10. A method according to claim 9 wherein the step of forming comprises distributing pleats along an edge of said margin at a density that varies locally to correspond to increasing and decreasing areas of curvature of the cushion that said margin covers.

11. A method according to claim 9 further comprising the step of sewing the non-stretch cord to said top edge of said skirt and the outer edges of said panel during said step of attaching.
