ABSTRACT:
An air bag inflator (10) includes a housing (12) open at one end. Inflator parts including gas generating material (70) are disposed in the housing (12). A retainer assembly (138) in the housing has a first part (170) expanded outwardly into interlocking engagement with a part (30) of the housing wall (14) adjacent the opening (24). This blocks movement of the retainer assembly (138) relative to the housing (12) toward the open end (24) of the housing (12). An end cap (90) is screwed into the open end (24) of the housing (12) after the retainer (140) is positioned in and interlocked with the housing (12). The retainer (140) is disposed intermediate the end cap (90) and the gas generating material (70). Because retainer (140) is disposed between the gas generating material (70) and a body of auto ignition material (122) in the end cap (90), a nozzle ( 150) is formed in the retainer (140) to direct auto ignition combustion products toward the gas generating material (70).
