<p>An air bag module (50) includes an air bag (70) having a circular bag opening (72) and a retainer plate (52) including a circular plate opening (58). A peripheral hem portion (76) surrounds the bag opening (72) and contains a discontinuous circular ring (100). The ring (100) has a relaxed position in which the ring (100) has a diameter greater than that of the plate opening (58). The ring (100) also has a deformed position in which the ring (100) has a diameter less than that of the plate opening (58) such that the ring (100) and air bag (70) are insertable through the plate opening (58). Upon insertion of the ring (100) through the plate opening (58), the ring (100) reopens to the relaxed position and is captured beneath the plate (52) such that the air bag (70) is anchored to the plate (52) and removal of the ring (100) back through the plate opening (58) is prevented.</p> |
