Abstract
Abstract A vehicle occupant safety apparatus including an inflatable air bag, an inflator for inflating the air bag, and a support plate for supporting the air bag and the inflator on a vehicle steering wheel. The safety apparatus further includes a retainer ring for clamping together the air bag, the inflator, and the support plate. The retainer ring has tabs which are bendable into positions for exerting clamping forces on the air bag, the inflator, and the support plate.
