To provide a seat constitution member and a mold of the seat constitution member in which a pad body is integrally foamed and molded with a skin material and the feeling of discomfort caused by a sewing line part on the skin material is suppressed.SOLUTION: In a cushion constitution member 10, a cushion pad 11 is integrally formed on a cushion cover 12. A top plate main part 12a and a top plate side part 12b in a plurality of pieces in which a surface layer part 12A and a foam layer part 12B constituting the cushion cover 12 are laminated are connected to one another with a sewing line L1. The top plate main part 12a includes a main part 12a1 and a main vertical wall part 12a2. The top plate side part 12b includes a side main part 12b1 and a side vertical wall part 12b2. A rear surface of the foam layer part 12B of the main part 12a1 and a rear surface of the foam layer part 12B of the main vertical wall part 12a2 intersect with each other to form an acute angle without any space therebetween. The rear surface of the foam layer part 12B of the side main part 12b1 and the rear surface of the foam layer part 12B of the side vertical wall part 12b2 intersect with each other to form an obtuse angle.SELECTED DRAWING: Figure 3
【課題】表皮材に対してパッド体を一体発泡成形するとともに表皮材の縫製ライン部の違和感を抑制したシート構成部材及びその成形型を提供する。【解決手段】クッション構成部材10は、クッションカバー12に対しクッションパッド11が一体成形されて形成されている。クッションカバー12を構成する表層部12Aと発泡層部12Bが積層された複数のピースの内の天板メイン部12aと天板サイド部12bが縫製ラインL1で連結されている。天板メイン部12aはメイン主部12a1とメイン立壁部12a2とを有し、天板サイド部12bはサイド主部12b1とサイド立壁部12b2とを有する。メイン主部12a1の発泡層部12B裏面とメイン立壁部12a2の発泡層部12B裏面は鋭角をなして隙間なく交わり、サイド主部12b1の発泡層部12B裏面とサイド立壁部12b2の発泡層部12B裏面とは鈍角をなして交わっている。【選択図】図3
