US 5,395,668 A · Air bag apparatus

Abstract

An air bag apparatus in which the appearance of the interface between the portion covering the air bag and portions surrounding it can be improved, the number of components can be reduced, and the assembly process can be shortened. A cover unit covers an air bag, which inflates on a predetermined occasion, consists of a cover which-opens with the inflation of the air bag, and a body for holding the cover. The cover unit is an integrally molded product in which a skin is formed on a substrate, and includes, at the location connecting the periphery of the cover with the body, a breakaway portion along which the cover is separable from the body when the air bag inflates, and a hinge portion for maintaining the connection of the body and the cover. In the breakaway portion, the substrate has a fragile portion, and the skin is separated into two parts at the position of the fragile portion. In the hinge portion, the substrate and skin are continuously formed and extend from the body to the cover.
