Abstract: An occupant restraint cushion system including a housing provided with a J-shaped base wall connected to a pair of laterally spaced end walls with one of the end walls having an enlarged circular opening formed therein and the other end wall having an aperture formed therein. A gas generator-diffuser combination is mounted in the opening with a threaded stud fixed with one end of the gas generator extending through the aperture and adapted to have a nut tightened thereon so as to draw the gas generator towards the associated apertured side wall to thereby concentrically locate the gas generator relative to the diffuser and simultaneously clamp portions of the cushion fabric between the gas generator and diffuser to provide the cushion with a sealed compartment.
