ABSTRACT:
An apparatus (20) for inflating an inflatable vehicle occupant protection device (22) comprises a container (24) which defines a chamber (26). Inflation fluid and ignitable material are in the chamber (26). The container (24) has an opening (60) through which inflation fluid may flow to inflate the protection device (22). A rupturable closure (62) blocks flow through the opening (60) in the container (24). A projectile (120) is supported by the container (24) in the chamber (26) at a location spaced from the closure (62). An actuatable igniter (104) is supported by the container (24) and produces combustion products to propel the projectile (120) to rupture the closure (62). The combustion products are directed into the chamber (26) to ignite the ignitable material in the chamber (26) before the projectile (120) ruptures the closure (62).
