An air bag cover and manufacturing method thereof wherein the air bag cover comprises a core member which can be formed by injection molding, and a decorative sheet disposed on the surface of the core member. The decorative sheet includes at least two layers, an outer layer and a barrier layer disposed on a back side of the outer layer to protect the outer layer when the core member is injection molded. The core member is made of thermoplastic elastomer which can be thermally fused to the barrier layer. A breakable portion is provided in the barrier layer and core member.

Method for manufacturing an air bag cover

An air bag cover is made of thermoplastic resin and covers an air bag. A plurality of holes are provided with the air bag cover continuously and a breakable portion is provided which severs upon the inflation of the air bag. The surface side of the breakable portion is processed by a heating process, so that protrusions which partially plug the holes are formed on the inner circumferential surface of the holes on the surface side.

Air bag cover and manufacturing method thereof

A molded article, useful as an interior part of a motor vehicle, is described. The molded article is formed by injecting a synthetic resin material as a base layer into a mold wherein a synthetic resin film has been placed in close contact with a wall of the mold. The base layer is composed of acrylonitrile butadiene-styrene copolymer or denatured acrylonitrile butadiene-styrene copolymer which is obtained by dispersing butadiene rubber particles within a matrix of acrylonitrile-styrene copolymer or denatured acrylonitrile-styrene copolymer. The acrylonitrile-styrene copolymer or denatured acrylonitrile-styrene copolymer matrix has a molecular weight distribution which is greater than 2.18 and less than 3.05.
