    摘要: The present invention relates to a gas generating apparatus for an air bag apparatus mounted in a vehicle or the like for protecting a passenger of the vehicle by charging a gas into an air bag interposed between the passenger and an interior member of the vehicle chamber so as to inflate the air bag at the time of collision of the vehicle. The gas generating apparatus for the air bag apparatus includes a first chamber 9 which accommodates a combustible fluid 7 and which is provided with a first vent opening 8 leading to the air bag 3; a second chamber 5 larger than the first chamber 9; a first occluding member 13 for occluding the first vent opening 8; and an ignition device 14 for igniting the combustible fluid in the first chamber 9. By burning at least a portion of the combustible fluid 7 within the first chamber 9, the fluid in the first and second chambers 9 and 5 is discharged through the first vent opening 8 to inflate the air bag 3. Since, the first occluding member is swiftly broken to discharge a mixture of the combustible fluid in the first chamber, it is possible to shorten the initial responding time period required to start inflating the air bag.
