Abstract
An air bag inflator (,) includes a container (,) defining a chamber (,), and inflation fluid (,) under pressure in the chamber. A first opening (,) in the container (,) enables fluid flow from the chamber (,) to an inflatable device (,). A first burst disk (,) extends across the first opening (,) and is rupturable in response to an increase in the pressure differential across the first burst disk to a level above a first predetermined pressure differential. The inflator (,) includes a first igniter (,) for, when actuated, increasing the pressure differential across the first burst disk (,) to a level above the first predetermined pressure differential to rupture the first burst disk. A second opening (,) in the container (,) enables fluid flow from the chamber (,) to the inflatable device (,). A second burst disk (,) extends across the second opening (,) and is rupturable in response to an increase in the pressure differential across the second burst disk to a second predetermined pressure differential greater than the first differential. The inflator (,) includes a second igniter (,) actuatable independently of the first igniter (,) for, when actuated, increasing the pressure differential across the second burst disk (,) to a level above the second predetermined pressure differential to rupture the second burst disk.
