ABSTRACT:
A vehicle seat is disclosed which is provided on its surface with a plurality of intersecting, recessed grooves for decoration. The seat includes a cushion member formed of a foam material and provided on its surface with a plurality of intersecting, recessed grooves. Projections are provided adjacent to the intersections of these recessed grooves, respectively. Such projections can prevent wrinkles from being produced in the intersections of the decorative recessed grooves formed in a top member which is a component of the seat. Specifically, when such top member placed over the cushion member is hung in along the recessed grooves of the cushion member, the recessed grooves for decoration are formed on the surface of the top member. During this hang-in operation, the projections are compressed so that repelling resilient forces are produced in these projections. Such resilient forces of the projections prevent any wrinkles from occurring in the intersections of the decorative recessed grooves in the top member.
