The air bag has a circular central opening flanked by 12 circumferentially-spaced mounting holes, and the base plate has a mating circular central opening and 12 circumferentially-spaced mounting holes, each corresponding to an air bag mounting hole. The inflator has four spaced mounting holes mating with four of the air bag and base plate mounting holes. The retainer ring has four circumferentially-spaced mounting holes corresponding to the four air bag and base plate mounting holes. Eight integral, circumferentially-spaced spring tabs are lanced out of the ring to extend from the surface of the retainer ring. The tabs correspond to the remaining eight air bag and base plate mounting holes. The ring is placed inside the air bag and the tabs are extended out through the air bag mounting holes.
