Structure of wadded-up seat trim cover and method of manufacturing wadded-up seat trim cover
First Claim
1. A method of manufacturing a wadded-up seat trim cover for covering a seat pad, the wadded-up seat trim cover having a plurality of trim cover pieces comprising a first trim cover piece and a second trim cover piece, each of the first and second trim cover pieces having an end and being sewn together at each said end, each of the first and second trim cover pieces composed of a wadding member and a skin member backed with the wadding member, each of the wadding member and the skin member having a length, wherein the length of the wadding member is less than the length of the skin member, the method comprising:
- a bonding step of bonding each of the skin members of the first and second trim cover pieces to a respective wadding member of the first and second trim cover pieces at a position spaced apart from a respective end of each of the wadding members of the first and second trim cover pieces such that a portion of each of the wadding members of the first and second trim cover pieces is overlapped by a respective skin member of the first and second trim cover pieces, thereby forming a bonded portion;
a first sewing step of bending a portion of each of the skin members of the first and second trim cover pieces such that the portion of each of the skin members of the first and second trim cover pieces does not overlap the wadding members of the first and second trim cover pieces, along the respective end of each of the wadding members of the first and second trim cover pieces and then sewing the skin members of the first and second trim cover pieces below the wadding members, thereby forming a first sewn portion; and
a second sewing step of bending ends of the skin members of the first and second trim cover pieces to respective backs of the first and second trim cover pieces at the first sewn portion and then sewing the skin members together at respective overlapping portions that clamp the first sewn portion, thereby forming a plurality of second sewn portions.

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.
