Abstract
A cover assembly for an air cushion restraint has a smooth cover with a layer of foam between the cover and a load bearing insert for covering a housing for an airbag and a gas generator which generates an inflatant for the airbag for deploying the airbag; the cover assembly includes a single cutter which has three blade edges of a depth to cut through the layer of foam and smooth cover before a cover insert member is actuated to form a three sided opening through the cover assembly through which the airbag is deployed; the single cutter is pivoted on a retainer insert member as the airbag is inflated to cause cutting edges on the cutter to pierce the smooth outer cover member. The cutter is recessed within the cover assembly to avoid incidental contact with the cutting edges prior to deployment. The cutter is bent to be self-retained following airbag deployment to shield the cutting edges from passenger contact during secondary impacts.
