In one embodiment, an air bag inflator (10) includes a canister (74) which has a lower canister section (76) and a canister cover (78). Disks (110) of gas generating material are located within a chamber (75) defined by the canister (74). A cushion (120) is located in the space between the uppermost disk (110U) and the canister cover (78). A wall (122) of the cushion (120) has a frustum shape prior to assembly of the inflator (10) and defines a cushion chamber (124). During assembly, the wall (122) of the cushion (120) is elastically bent into the cushion chamber (124). In another embodiment, an air bag inflator (160) includes a housing (176). Grains (212, 216) of gas generating material are located within a chamber (182) in the housing (176). A cushion (260) is located in a space between the last grain (216R) and the end cap (226). A wall (262) of the cushion (260) has a frustum shape prior to assembly of the inflator (160) and defines a cushion chamber (264). During assembly, the wall (262) of the cushion (260) is elastically bent into the cushion chamber (264). In both embodiments, the cushion (120 or 260) inhibits movement of the gas generating material with a force which is substantially constant and unrelated to the distance (D1 or D2) between the gas generating material (110U, 216R) and the canister cover (78) or end cap (226).
