Abstract
Abstract A cover assembly for an occupant restraint system is formed of relatively irrupturable material and includes longitudinal and lateral portions which overlie like portions of a container housing an inflatable occupant restraint cushion. The juxtaposed edges of these portions are arranged which are juxtaposed to each other across a tear line of the container. One edge of each pair terminates in a U shaped return bent flange and the other edge of each pair terminates in an S shaped return bent flange having a flap which extends across the tear line and abuts the U shaped flange.
