PROBLEM TO BE SOLVED: To rapidly mix propellant gases with a pressurized medium and rapidly burn the mixture under pressure in order to inflate an air bag. SOLUTION: A housing 212 comprises a first chamber 254 which contains a propellant 258, a propellant ignition assembly 228, a second chamber 324, an outlet port 286, and a main closure disk 290. The second chamber 324 is interconnected with the first chamber 254 and a housing 204 to combust propellant gases generated by the ignited propellant with a pressurized medium, which supplies from the outlet port 286 to an air bag. The main closure disk 290 normally blocks the outlet port 286 and is ruptured after ignition of the propellant. The housing 212 comprises a bleed port 262 for substantially equally maintaining internal pressures of the housing 204 and the first chamber 254. |
