Abstract: A part of the planar member, which is defined by the slits and extends over the center groove made in a seat pad, serves as a bridge part. As the sewn part of a trim cover is pulled into the groove, the bridge part is pressed onto the sewn part of the trim cover and pulled into the groove, together with the sewn part, and is bend in the form like letter U and held in the groove. The groove defines a through hole penetrating the seat pad at the bridge part of the planar member. The bridge part is not pressed onto the bottom of the groove even if the seat pad undergoes compressive deformation and is pressed down in the groove, because the groove has no bottom at some parts.
