The present invention provides a seat frame inflator including a seat frame housing portion formed of a seat frame having a hollow structure and forming an outer shell of a pressurized gas chamber, and a partition member disposed on a hollow side of the seat frame and configured to isolate the pressurized gas chamber and a gas chamber outer region from each other. The partition member is provided with a communication hole, and a closing member configured to close the communication hole. The seat frame inflator includes an opening member disposed on the hollow side of the seat frame, and configured to open the pressurized gas chamber, and a gas discharge port formed in the seat frame to face the gas chamber outer region and configured to discharge, from the gas chamber outer region to the outside, the pressurized gas flowing from the pressurized gas chamber.

The invention relates to an overigniting protection device (40) for a multi-stage gas generator (10), comprising a combustion chamber limiting element (34) for limiting a combustion chamber (30) of a second ignition stage (14) of the gas generator (10) as well as an overigniting protection element (38) which is arranged on a side of the combustion chamber limiting element (34) remote from the combustion chamber (30), wherein the overigniting protection element (38) covers the side of the combustion chamber limiting element (34) remote from the combustion chamber (30), wherein the overigniting protection element (38) is tightly connected to the combustion chamber limiting element (34) via a mounting portion (42) and wherein the overigniting protection element (38) is substantially plate-shaped or completely covers the side of the combustion chamber limiting element (34) remote from the combustion chamber (30). Furthermore, the invention relates to a second ignition stage (14) of a multi-stage gas generator, a gas generator (10) and an airbag module comprising a gas generator (10).

In a hybrid inflator, a housing houses a gas generator to generate a combustion gas in a housing recessed portion on a bottom portion side. A lid body provided at an outflow port of the housing and a lid body provided at a sealed portion side of a pressurized gas in a bottle in a gas discharge port portion separate the sealed portion of the pressurized gas in the bottle from outside. When the hybrid inflator is activated, the two lid bodies are broken by generation of the combustion gas from the gas generator, and whereby the pressurized gas is discharged from a discharge port of the gas discharge port portion. The gas generator is detachably assembled to the housing with respect to the housing recessed portion of the housing.

Provided is an airbag device in which an inflator can be fixedly mounted easily. The airbag device includes an inflator which generates a gas; an airbag which is inflated by the gas generated by the inflator; a retainer which is provided with an insertion port into which the inflator is inserted; a bag ring which mounts the airbag in the retainer; and a spring which fixes the inflator inserted into the insertion port.
