Abstract
An airbag module combining assembly and mounting components and steps. The module includes an inflator having a mounting flange. The cushion mouth rests upon a top side of the flange. A rigid retaining member rests above the cushion mouth to secure the cushion to the flange. The retaining member includes studs which extend through mating holes in the cushion and flange. The free ends of the studs extend beyond the bottom of the flange. A cover fits over the folded cushion and includes a plurality of flaps extending downward. The ends of the flaps are folded under the flange and fit over the studs. Temporary restraints, such a friction lock washers are secured over the studs to secure the cushion, inflator and cover flaps between the retaining member and temporary restraints. The partially assembled module may be shipped in this condition. The extending free ends of the studs may then be inserted into mounting brackets in the vehicle, and permanent nuts fixed thereon. This firmly secures the cushion and cover to the inflator, and completes assembly of the module with the mounting step. This design further permits the use of a simplified cover flap which is easier to produce.
