Abstract

A trim cover includes: a plurality of skin materials; and a sewing part formed by sewing two skin materials of the plurality of skin materials with multiple rows of seams which extend in parallel with a sewing line of the two skin materials. In the trim cover formed by sewing the plurality of skin materials, the inclining direction of the seam allowances of the two sewn skin materials can be easily made constant so as to suppress the meandering of the sewing line of the two skin materials, and the appearance quality of the vehicle seat covered with the trim cover can be improved.
