An air bag inflator (20) comprises a container (40) defining a chamber (48) for storing inflation fluid at a first pressure. A rupturable closure or rupture disk (102) extends across an opening (60) in the container (40). Each one of a pair of inflation fluid heating assemblies (122, 124) is located

An air bag inflator (20) comprises a container (40) defining a chamber (48) for storing inflation fluid at a first pressure. A rupturable closure or rupture disk (102) extends across an opening (60) in the container (40). Each one of a pair of inflation fluid heating assemblies (122, 124) is located in the chamber (48) and includes an actuatable igniter (222) and an ignitable material (168). The igniter (222) in one inflation fluid heating assembly (122) upon actuation, ignites the ignitable material (168) in the one inflation fluid heating assembly to produce combustion products. The combustion products heat the inflation fluid and increase the pressure of the inflation fluid in the chamber (48) to a second pressure to rupture the rupture disk (102). The igniter (222) in the other inflation fluid heating assembly (124), upon actuation, ignites the ignitable material in the other inflation fluid heating assembly to produce combustion products which further heat and further increase the pressure of the inflation fluid in the chamber (48).
