ABSTRACT:
A cover assembly for an air bag restraint system has a smooth outer skin with a backing layer of foam located between the outer skin cover and a retainer member. The retainer member is located above the outlet of an air bag casing and includes a plurality of flaps therein each having a pointed end located in a hidden position beneath the foam and outer skin cover and at a point generally centrally of the outlet of the casing. Each of the flaps is connected to the retainer member by integral hinge segments in the retainer member. When the air bag is inflated, it will cause the segments to pivot outwardly about the hinge segments to pierce both the foam layer and the outer skin and peel them apart so as to form a multi-sided opening through the cover assembly for deployment of the air bag.
