Abstract
An interior finish member having a door suitable for an air bag comprises a main body and a cover portion. The main body surrounds the periphery of the cover portion, and the main body and the cover portion form a continuous surface. The cover portion covers a folded air bag of an air bag device. The cover portion comprises: a door portion which covers the folded air bag; a breakable portion defined by a recessed periphery of the door portion whose thickness is thinner than adjacent portions of the interior finish member so that it may be broken easily in deployment of the air bag; and a hinge portion for connecting the door portion with the main body and for providing a pivot around which the door portion rotates when the door portion opens under a force of an expanding air bag. The main body is made of thermoplastic resin, and the cover portion is made of thermoplastic elastomer. Because they are capable of thermally fusing with each other, the main body and the cover portion can be integrally formed.
