  • Method of sewing process for trim cover of vehicle seat and vehicle seat using same
    Patent number: 10378137
    Abstract: Regarding a method of a sewing process for a trim cover of a vehicle seat provided with a decorative band, conventionally, a decorative band made up of a covering and wadding is sewn to a member of a trim cover similarly made up of a covering and wadding. Because of this, an area where a decorative band is sewn has an increased thickness, causing discomfort when an occupant sits. To address this, in the example embodiment, a sewn covering is manufactured by sewing together coverings for a portion of a trim cover and a decorative band and sewing decorative stitching through the sewn ends, and then the sewn covering and wadding are overlaid on each other to sew their borders together. This makes it possible to reduce the thickness of an area where the decorative band is sewn and reduce the discomfort when an occupant sits.
