A vehicle air bag installation includes an inflatable air bag mounted in an instrument panel recess for deployment through a rectangular opening.

Interengageable surfaces on the door and panel have an interference fit to retain the door front edge mounted to the panel. Each fastener has a conical mounting shank having a nipple extending from its end. The nipple extends through and beyond the apertures to enable it to be grasped to deform and pull the shanks through the apertures to secure the fasteners against removal. Air bag inflation applies an upward force to the door which initially disengages the interengageable surfaces which frees the front door edge…
