PURPOSE:To realize the precise and easy mounting of a trim cover to a mold so as to obtain the correctly formed shape and to reduce its defect rate by a method wherein the trim cover is mounted onto the open surface of either a bottom force or a top force in such a state that the body part of the trim cover is turned inside out and, after that, the trim cover is pressurized and finally urethane molding is expansion-molded onto the cover. CONSTITUTION:A skin material 20, which is formed by laminate-bonding a skin 1 and a wadding 2, is produced by being cut in the shape of a seat body having a gusset part 3, and mounted onto a bottom force 5 inside out. When the skin material 20 under the above-mentioned state is heated with a heater 6, the gusset part 3 on the side of the bottom force 5 does not be heated. Next, the skin material 20 consisting of the skin 1 and the wadding 2 is, for example, pressurized with a top force 7 so as to be formed in the desired seating face shape. Next, a molding top force 8 is placed onto the skin material 20 so as to pour molding stock from the molding stock inlet 8a of the molding top force 8 in the force 8. After the completion of foaming, the molding top force 8 is taken up. Next, the skin material 20 is removed together with its gusset part 3 and a urethane molding 4 from the bottom force 5 in order to complete a seat body by covering the urethane molding 4 by the gusset part 3, which is turned downside up. |
