Title:
GAS GENERATOR
Document Type and Number:
WIPO Patent Application WO/2007/037362
Kind Code:
A1
Abstract:
A gas generator (1A) having an approximately cylindrical housing and, disposed inside the housing, an ignition chamber (13), first and second combustion chambers (23 and 33), and first and second discharge passageways. The ignition chamber (13) is disposed in a base part (10) of the housing and contains an ignition device (12) and an ignition charge (14) charged therein. The first and second combustion chambers (23 and 33) are disposed respectively in first and second cylindrical parts (20 and 30) of the housing and each contains a gas generator charged therein. The first and second discharge passageways are disposed respectively on the front end sides of the first and second cylindrical parts (20 and 30) of the housing and serve to enable gases generated in the first and second combustion chambers (23 and 33) to be discharged from the housing therethrough. The inner diameter (r1) of the first combustion chamber (23) and the inner diameter (r2) of the second combustion chamber (33) are suitably regulated so as to differ from each other. In this gas generator, which has such constitution including two or more gas output parts operated by one ignition device, the outputs of the gas output parts can be made different while preventing the apparatus size from increasing and the rise in gas output from decreasing.
