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.

Gas generating device for air bag and air bag inflating method

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.

Gas generating apparatus for air bag apparatus and method for inflating air bag

A charging method of a combustible gas and an oxidizer gas includes the steps of charging the combustible gas, and charging the oxidizer gas, both into a container through a charging port provided to the container. During at least one of two charging steps, a composition of a combustible mixed gas created in the vicinity of the charging port is controlled in a nonflammable range.

Charging method and charging structure of combustible gas and oxidizer

A charging structure of a combustible gas and an oxidizer gas includes a container for containing the combustible and oxidizer gases therein. The container has a charging port for charging the combustible and oxidizer gases. The charging structure also includes a sealing member for sealing the charging port and a separating member for substantially separating the combustible gas and the oxidizer gas at least in the vicinity of the charging port during a predetermined time period beginning, from a time point after charging of the combustible and oxidizer gases into the container through the charging port to a time point when the charging port is sealed by the sealing member. The separating member defines a flow path such that the combustible gas and the oxidizer gas are not substantially mixed therein during the predetermined time period in such a case where one of the combustible and oxidizer gases is first charged and thereafter the other of the combustible and oxidizer gases is charged.
