TIP-102 Abstract of the Disclosure CLOSURE: FOR AN AIR BAG DEPLOYMENT OPENING A closure arrangement for an air bag deployment opening formed in an auto interior, including a closure panel positioned in the opening and hinged along one side, with a frangible lock on the other side opposite the hinge, fractured by pressure exerted by the deploying inflatable cushion. In a first embodiment, the frangible lock is defined by a tab portion of a foam plastic core body of the closure panel protruding into a recess formed in an adjacent structure, or an additional lock attached to the cannister, the tab fractured by being sheared off after the inflatable cushion contacts an inside protuberance projecting from the inside of the closure panel or additional lock attached to the cannister; and, the hinge is provided by bending of an convoluted-shaped section of a formed aluminum layer defining the inner side of the closure panel. In a second embodiment, a molded plastic panel member has an inward frangible flange with tabs secured to an air bag cannister or instrument panel structure to provide the lock, and the tabs are fractured by tensile loading created by deployment of the inflatable cushion. An inwardly directed integral hinging flange is also adapted to be connected to the air cushion cannister or instrument panel structure.
