Abstract
A trim cover assembly forming the surface of a vehicle seat such as an automotive seat is disclosed which comprises a three-layer lamination composed of a thermally weldable covering material, a wadding formed of a thermally weldable foam material and a wadding cover. In the trim cover assembly, the three-layer lamination is pressurized and heated by a high frequency welding machine to form a plurality of recessed grooves in one or more main bodies of the trim cover assembly and at the same time to provide a plurality of joint portions, which are formed by collapsing the above-mentioned three elements of the trim cover assembly, along the ends of the trim cover assembly lying in the extensions of the recessed grooves, so that the intersections of the recessed grooves and joint portions are regularly folded to facilitate the positive and fine welding of other components of the trim cover assembly to the joint portions.
