Abstract
A method for manufacturing a covering system for a motor vehicle seat member includes the steps of: providing a support, a cover and a pad; associating the support with the cover, the pad being left free between the support and the cover; and creating longitudinal seam lines, one on either side of the pad. The longitudinal seam lines join together the support and the cover. The longitudinal seam lines form straight segments, extending in a transverse direction towards the first pad, and join together the support, the cover, and the first pad.

A method for manufacturing a covering system for a motor vehicle seat member, comprising the steps of:
- i) providing a support, a cover, and a first pad;
- ii) associating the support with the cover such that the first pad is left free between the support and the cover;
- iii) creating first and second longitudinal seam lines, one on either side of the first pad, the first and second longitudinal seam lines having a main portion extending substantially in a longitudinal direction and joining together the support and the cover, the first and second longitudinal seam lines respectively forming, in addition to a longitudinal main portion of the first longitudinal seam line and a longitudinal main portion of the second longitudinal seam line, at least one first straight segment and at least one second straight segment, the first and second straight segments respectively extending from the main portion of the first and second longitudinal seam lines in a transverse direction towards the first pad, the first and second straight segments joining together the support, the cover, and the first pad, wherein the at least one first straight segment extends only partially toward the second longitudinal seam line;
- and
- further comprising subsequent to step iii), a step of:
- iv) creating at least one first transverse seam line extending between the main portion of the first longitudinal seam line and the main portion of the second longitudinal seam line, the first transverse seam line joining together the cover, the support, and the first pad such that said at least one first transverse seam line is superimposed on the first straight segment at a first end, and on the second straight segment at a second end.
A covering system for a motor vehicle seat member, comprising a support, a cover, and a first pad interposed between the support and the cover,
- wherein the support and the cover are joined together by first and second longitudinal seam lines extending one on either side of the first pad,
- the first longitudinal seam line having a longitudinal main portion, and at least one first transverse straight seam segment extending transversely from the longitudinal main portion of the first longitudinal seam line and on the same side as the first pad, the at least one first straight seam segment joining together the support, the cover, and the first pad, wherein the at least one first transverse straight seam segment extends only partially toward the second longitudinal seam line,
- the second longitudinal seam line having a longitudinal main portion, and at least one third transverse straight seam segment extending transversely from the longitudinal main portion of the second longitudinal seam line and on the same side as the first pad, the at least one third straight seam segment joining together the support, the cover, and the first pad, wherein the support and the cover are also joined together with the first pad by at least one first transverse seam line, the at least one first transverse seam line extending, near the first longitudinal seam line, parallel to the first transverse straight seam segment, and
- the at least one first transverse seam line extending, near the second longitudinal seam line, parallel to the third transverse straight seam segment.
A covering system for a motor vehicle seat member, comprising a support, a cover, and a first pad interposed between the support and the cover,
- wherein the support and the cover are joined together by first and second longitudinal seam lines extending one on either side of the first pad,
- the first longitudinal seam line having a longitudinal main portion, and at least one first transverse straight seam segment extending transversely from the longitudinal main portion of the first longitudinal seam line and on the same side as the first pad, the at least one first straight seam segment joining together the support, the cover, and the first pad,
- the second longitudinal seam line having a longitudinal main portion, and at least one other transverse straight seam segment extending transversely from the longitudinal main portion of the second longitudinal seam line and on the same side as the first pad, the at least one second straight seam segment joining together the support, the cover, and the first pad, and
- a transverse seam line superimposed over and stitched on top of the at least one first transverse straight seam segment of the first longitudinal seam line and the at least one other transverse straight seam segment of the second longitudinal seam line.
