Abstract
An air bag cover having an opening portion that has a tear line at which the opening portion is torn by a predetermined pressure, and a mounting portion that has a mounting hole for insertion of a fastener for attaching the cover to another member. The opening portion is made of a thermoplastic elastomer, while the mounting portion is made of a rigid thermoplastic synthetic resin material. The opening portion and the mounting portion are integrally welded together under high pressure. The air bag cover is produced by a method comprising the first step of injecting the thermoplastic elastomer through a first gate into a first cavity for forming the opening portion, and the second step of injecting the thermoplastic synthetic resin material through a second gate into a second cavity communicated with the first cavity for forming the mounting portion. In the first step, the opening portion is formed with the second cavity closed. In the second step, the mounting hole of the mounting portion is formed with a movable pin inserted into the second cavity. The second step may be carried out either after or simultaneously with the first step.
