Abstract
An air bag module (10) includes a housing (12). An air bag (22) is folded and stored in the housing (12). A retaining ring (30) secures the air bag (22) to the housing (12). The retaining ring (30) includes two relatively movable U-shaped members (152, 154). Assembly tabs (210, 212, 252, 254) on the retaining ring members (152, 154) are gripped to move the retaining ring (30), in a collapsed condition, in one direction (32) through a deployment opening (150) into the housing (12). The retaining ring (30) is then expanded and moved in an opposite direction (34) to interlock with the housing (12).
