摘要： A panel for an airbag of an automobile is formed by integrally molding a cover body, which is made of a synthetic resin, with a main body, made of another synthetic resin. The panel includes a joint portion, joined with the cover body, and provided around an opening portion formed in the main body. The joint portion constitutes an overlapping portion in which an outer peripheral edge of the cover body is overlapped as being arranged on the inner side of an opening edge of the main body.

摘要： Disclosed is a method of molding an automobile outer trim part, including the steps of: (1) providing a film or sheet comprising a colored layer composed of a propylene polymer composition and, laminated thereto, a clear layer composed of a propylene homopolymer, (a) heating the laminated film or sheet, (3) feeding the heated laminated film or sheet into a metal mold including a pair of dies, (4) closing the metal mold so that the laminated film or sheet is shaped into desired configuration, (5) loosing the closed metal mold, and (6) injecting a thermoplastic polymer onto the side of the colored layer of the metal mold so that the shaped laminated film or sheet is united with a substrate layer of the thermoplastic polymer. The above propylene polymer composition comprises in a specified proportion a polypropylene block copolymer and/or polypropylene random copolymer exhibiting a specified intrinsic viscosity, a polyethylene exhibiting a specified intrinsic viscosity, an elastomer composed of a copolymer of ethylene and an .alpha.-olefin exhibiting a specified intrinsic viscosity and a colorant. The above method enables providing an automobile outer trim part having the same colored appearance and texture as those of painted part, irrespective of the avoidance of a printing step.
