ABSTRACT:
An air bag cover door assembly utilizes a releasable fastener along each side of the air bag cover door to provide a predetermined opening characteristic for the cover door. The fasteners can be hook and loop tape, mechanical interlocks, adhesive strips, etc., with one half of each fastener secured to the inside surface of the cover door and the other half secured to a substructure, such as a dashboard pad retainer, in mating engagement with the first half. The fasteners are located along the sides of the cover door proximate the hinging axis of the cover door so that expansion of the air bag causes the cover door to initially hinge along a line extending between the engaged fasteners and then causes the fasteners to separate, allowing the cover door to swing open fully about its hinging axis. This reduces the speed of the cover door as it fully opens, thereby directing the air bag rearwardly toward the occupant and reducing the possibility of windshield breakage when the cover door assembly is used in a passenger side, top mount position of an automobile.
