In existing manufacturing methods wherein a bonded seat is formed by adhering a surface skin material to a pad made from molded foam, defects may occur from curing of the adhesive, such as reduced flexibility and a poor texture on the seat contact surface. In addition, the manufacturing steps therefor are complicated. In order to solve the above problems, the present invention provides a manufacturing method for a vehicle seat having a molded pad and a trim cover that covers the molded pad. The molded pad has a groove, and an adhesive is applied to the inside of the groove. The trim cover is pressed into the inside of the groove, and a steam nozzle is inserted into the molded pad from the surface of the molded pad opposite from the surface covered by the trim cover. Heat or steam from the steam nozzle melts the adhesive inside the groove so as to adhere the trim cover to the groove. It is thus possible to provide a vehicle seat and a manufacturing method therefor with which a contact surface can exhibit a good texture and manufacturing steps can be simplified.

A vehicle seat includes a pad having an air passage, a skin material, and a skin locking clip embedded in the pad and configured to tuck in a prescribed linear portion of the skin material. The pad includes a main body member in which the skin locking clip is embedded, an intermediate layer member arranged on the main body member, and a surface layer member arranged on the intermediate layer member. The main body member includes a linear bulging portion extending along the linear portion and bulging so as to define a plane substantially identical to a surface of the surface layer member, and the skin material is tucked in by the skin locking clip at a portion extending further from the surface layer member than the linear bulging portion.

A skin locking clip that is firmly supported by a pad is provided. The skin locking clip (10) is disposed in a groove (8) of a pad (5) of a vehicle seat or the like, and fixes a locked portion (6c) attached to a skin material. The skin locking clip (10) includes a base plate (11), a locking piece (12) erected on the base plate (11) to lock the locked portion (6c), and an overhanging piece (13) erected on the base plate. Since the overhanging piece (13) is supported by the pad (5), the skin locking clip (10) is firmly supported by the pad (5).

In order to solve the issue, during recessed-shape molding for vehicle seats, of requiring a suspension step, more work, members for suspension, and increased cost in a method using suspension, a recessed-shape molding method is provided for vehicle seats having a seat frame, a seat pad covering the seat frame, and a trim cover covering the seat pad. The seat pad has a seat pad groove. An adhesive sheet is sewn on to the rear surface of the trim cover by using outer stitching, the trim cover is put on to the seat pad, then a die is pressed on to the outer stitching from the trim cover surface, the trim cover is adhered to the seat pad groove, and a recessed shape is formed. As a result, a vehicle seat having simplified molding steps and effectively reducing costs can be provided, as well as a vehicle seat molding method used for same.

A vehicle seat (1) includes a seat frame (6), an elastic sheet (9) mounted to the seat frame in a tensioned state (6), and a trim (10) provided on the elastic sheet (9). The elastic sheet (9) includes a fastening section including a fastening plate (16) for the trim (10). The trim (10) includes a trim body (11) and a trim end (15) that is attached to the trim body (11) and fastened to the fastening plate (16) with the trim body (11) being stretched.

A recessed seam structure for a cover (3) that improves workability when forming a recessed seam (A) and allows frequent attachment and detachment at the recessed seam (A) is provided. In a seat (1) having the recessed seam (A) formed by pulling part of the cover (3) toward a side of a cushion material (2), the recessed seam (A) is provided with an opening and closing fastener (30) configured to couple the cover (3) and the cushion material (2), and the opening and closing fastener (30) includes a first fastener half (31) fixed to a back face of the cover (3) and a second fastener half (32) fixed to the cushion material (2). In such a seat (1), the recessed seam (A) can be formed easily and reliably on the seat (1) by aligning an end of the first fastener half (31) in a longitudinal direction and an end of the second fastener half (32) in the longitudinal direction of the opening and closing fastener (30) and simply sliding a slider (33).

An apparatus for upholstering a truss allows an operator to staple a fabric web to the truss, rotate the truss, further staple the semi-finished truss and cut the fabric web. The truss is fully upholstered after the end surfaces of the truss are wrapped up in fabric and the fabric stapled in place. The apparatus may accommodate different size trusses. A web of fabric is pulled around at least one roller in the apparatus by rotation of two vise mechanisms on opposite sides of the truss.
