Vehicle interior member having air bag door portion and method for molding the same

摘要

A vehicle interior member with an air bag includes an air bag door portion that can be made to be invisible and of improved construction. The vehicle member includes a skin molded to a substrate. The skin includes a tear line formed by a diagonal cut portion. In the vicinity of a lateral tear line of the skin side tear line, a projecting portion is provided on a lower mold to form a groove portion of the substrate along the diagonal cut portion so as to intercept a flow of a resin from the cutting direction of the diagonal cut portion. Therefore, as the resin flows in a reverse direction to the cutting direction of the diagonal cut portion at an opening portion thereof, a flow of the resin into a polypropylene foam layer of a three-layer skin through the opening portion of the diagonal cut portion can be suppressed. This prevents the polypropylene foam layer from being melted and damaged.
