ABSTRACT:
A method for integrally molding a preassembled door within an instrument panel to provide a cover for a safety air cushion device includes the steps of molding the plastic instrument panel about and over the door in situ of a mold cavity and thereafter the step of removing a portion of the instrument panel which overlies the door to provide an opening therein to expose the door for opening movement with respect to the instrument panel upon deployment of the air cushion device. The invention further includes the resultant structure of an integrally molded door and instrument panel assembly having an opening formed in the instrument panel assembly for both defining a ledge to support the door and to define a path for impacting an air cushion device against the door to cause the door to be lifted from its integrally molded seat relationship on the ledge for further deployment of the air cushion device into the passenger compartment of a vehicle.
