Document Type and Number:
WIPO Patent Application WO2003016093
Kind Code:
B1
Abstract:
A multi-level inflator for an air bag or other safety restraint device, comprising an elongated pressure vessel having a primary gas generating portion with a first open end and a gas storage portion (24) with a second open end. The primary gas generating portion has a primary initiator (16) and primary gas generating energetics (30) disposed therein, the initiator being mounted on an igniter body secured to and closing the pressure vessel at the first open end thereof. A pressure vessel closure (40) is secured to the second end of the pressure vessel, the closure having an aperture therethrough and a primary rupture disk (50) secured thereto to close the aperture. The gas storage portion has an inert gas therein under a predetermined pressure. A secondary inflator of the all-pyro type is secured to the pressure vessel and closure at the second end thereof. The secondary inflator comprises a secondary housing having a secondary initiator and secondary gas generating energetics disposed therein. A choke plate (66) having an opening therethrough is positioned between the secondary energetics and the pressure vessel closure. A secondary rupture disk (70) is secured to the choke plate to close the opening therein.
