The present invention relates to a gas generator for an air bag apparatus mounted in a vehicle or the like for protecting an occupant in the vehicle by charging gas into the air bag interposed between the occupant and a vehicle member at the time of collision of the vehicle. The gas generator for the air bag of the present invention comprises a first chamber ( ) accommodating a flammable fluid ( ) having a first vent opening ( ) which is in communication with the air bag ( ), a second chamber ( ) accommodating the flammable fluid ( ) and having a volume greater than that of the first chamber ( ), a first occluding member ( ) for occluding the first vent opening ( ), and an ignition device ( ) for igniting the flammable fluid ( ) in the first chamber ( ). By burning at least a portion of the flammable fluid ( ) in the first chamber ( ), the fluid in the first chamber ( ) and the second chamber ( ) is discharged out through the first vent opening ( ), thereby inflating the air bag ( ). Therefore, since the first occluding member is swiftly destroyed and burnt fluid mixture in the first chamber is discharged, it is possible to shorten the initial responding time at which the air bag starts inflating.

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,which accommodates a combustible fluid,and which is provided with a first vent opening,leading to the air bag,; a second chamber,larger than the first chamber,; a first occluding member,for occluding the first vent opening,; and an ignition device,for igniting the combustible fluid in the first chamber,. By burning at least a portion of the combustible fluid,within the first chamber,, the fluid in the first and second chambers,and,is discharged through the first vent opening,to inflate the air bag,. 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.
