Abstract
A self piercing cover assembly for concealing an air bag restraint system in a vehicle passenger compartment has a plurality of retractable cutter blades that are attached to the underside of an invisible door beneath the instrument panel by leaf springs. When the air bag inflates, it pushes the cutter blades out against the bias of springs to cut through the instrument panel at several locations along the front edge of the door making it easier for the door to swing open. The cutter blades retract under the action of the leaf springs so that the cutting edges are below the surface of the cover assembly to protect against contact with the cutting edges after the air bag collapses.
