The application relates to a seat assembly, a trim cover assembly, and a method of assembling. An assembly is provided with a seat member comprising a seating surface with a groove, a first trim layer, a second trim layer attached to the first trim layer, and one or more retaining members attached to the second trim layer. The second trim layer is positioned between the first trim layer and the one or more retaining members. The one or more retaining members are received within the groove, with the one or more retaining members connecting the first trim layer to the seat member. A trim cover assembly, and a method are also provided. In various non-limiting examples, the trim assembly may provide the desired shape of the seat, maintain durability and appearance, prevent looseness, and conceal the attachment of the retaining member.

The present invention relates to a sewing structure for a seat cover, comprising a first cut piece (1), a second cut piece (2), a first sewing thread (3), a second sewing thread (4) and an inlay (5), wherein the first and the second cut piece in an overlapped status are sewn together by the first and the second sewing thread which are spaced apart from each other, wherein the inlay is arranged between the first and the second cut piece and between the first and the second sewing thread.

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.
