Abstract
An air bag module (14) includes a cylindrical inflator (24), a wall structure (56), and a ring (120) extending through an opening (72) in the wall structure (56). The ring interlocks the inflator (24) with the wall structure (56) in a predetermined orientation circumferentially about a central axis (27) of the inflator (24). The ring (120) has first and second parts (160, 162) which are bonded together. The first part (160) of the ring (120) has an annular shape, and is formed of a first material. The second part (162) of the ring (120) extends circumferentially around the first part (160), and is formed of a second, harder material.
