Abstract
An apparatus (10) for use in inflating a vehicle occupant restraint includes a storage chamber (22b) which stores a gas under pressure, and an ignitable material (46b) which produces combustion products when burning. The ignitable material (46b) is contained in a combustion chamber (108b). The combustion chamber (108b) communicates with the storage chamber (22b) before the ignitable material is ignited. The combustion chamber (108b) is closed and isolated from the storage chamber (22b) when the ignitable material (46b) is burning. A burst disk (200) is ruptured by the combustion products in the combustion chamber (108b) to permit passage of the combustion products into the storage chamber (22b) when the combustion products reach a predetermined elevated pressure.
