STRUCTURE OF WADDED-UP SEAT TRIM COVER AND METHOD OF MANUFACTURING WADDED-UP SEAT TRIM COVER
First Claim
1. A structure of wadded-up seat trim cover for covering a seat pad, having a plurality of trim cover pieces sewn together at one end, each composed of a wadding member and a skin member backed with the wadding member, the structure comprising:
- a bonded portion formed by bonding the skin member to the wadding member made shorter than the skin member, at a position remote, by a prescribed distance, from the end of the wadding member overlapping the skin member;
a first sewn portion formed by bending that portion of the skin member, which does not overlap the wadding member, along the end of the wadding member and then by sewing the portions of the adjacent skin members together below the adjacent wadding members; and
second sewn portions formed by bending each end of the adjacent skin member to the back of the trim cover piece at the first sewn portion and then by sewing the adjacent skin members together at overlapping portions that clamp the first sewn portion.

Abstract
A structure of wadded-up seat trim cover, having a plurality of trim cover pieces sewn together at one end, each composed of a wadding member and a skin member, includes a bonded portion formed by bonding the skin member to the wadding member made shorter than the skin member, at a position remote, by a prescribed distance, from the end of the wadding member overlapping the skin member; a first sewn portion formed by bending that portion of the skin member, not overlapping the wadding member, along the end of the wadding member and then by sewing the portions of the adjacent skin members together; and second sewn portions formed by bending each end of the adjacent skin member to the back of the trim cover piece at the first sewn portion and then by sewing the adjacent skin members together at overlapping portions.

4. A method of manufacturing a wadded-up seat trim cover for covering a seat pad, having a plurality of trim cover pieces sewn together at one end, each composed of a wadding member and a skin member backed with the wadding member, the method comprising:
-
a bonding step of bonding the skin member to the wadding member made shorter than the skin member, at a position remote, by a prescribed distance, from the end of the wadding member overlapping the skin member, thereby forming a bonded portion; a first sewing step of bending that portion of the skin member, which does not overlap the wadding member, along the end of the wadding member and then sewing the adjacent trim over pieces below the adjacent wadding members, thereby forming a first sewn portion; and a second sewing step of bending each end of the adjacent skin members to the back of the trim cover piece at the first sewn portion and then sewing the adjacent skin members together at overlapping portions that clamp the first sewn portion, thereby forming second sewn portions. - View Dependent Claims (5, 6)
