Gas generator
First Claim
1. A gas generator, comprising:
- ignition means;
a gas generating agent ignited by the ignition means to generate gas by combustion; and
a housing including a gas generating agent storage chamber filled with the gas generating agent, the gas generating agent storage chamber being defined by the housing;
wherein;
the gas generator is configured to operate in and be held between a pair of plate members of a seat belt pretensioner apparatus, the plate members being arranged in parallel and respectively above and below the gas generator;
the housing comprises a deformable area that is deformed to reduce a height of the gas generator when the gas generator is held between the pair of plate members; and
the housing comprises at least one of a top plate and a bottom plate and the deformable area is provided on the at least one of the top plate and the bottom plate.

Abstract
A gas generator, including an igniter, a gas generating agent ignited by the igniter and generating gas by burning, and a holder and an AC cup forming therein a gas generating agent storage chamber filled with the gas generating agent. A housing formed of the holder and the AC cup is vertically held and fixed by a pair of plate-like members arranged parallel with each other. The gas generator also includes projections forming deformable areas which are deformed in a direction for decreasing the vertical outside dimensions of the gas generator when the housing is fixed by the pair of plate-like members. Thus, when the gas generator is fixed by the pair of plate-like members in the vertical direction, the dispersion of the outside dimensions of the gas generator can be absorbed.
