GAS GENERATOR FOR AIR BAG

摘要

A downsized gas generator for air bags having two combustion chambers between which the volume ratio can be easily adjusted is disclosed. An inner cylinder (15) disposed within a housing (11) has diameters changing along the height. Consequently, the volume ratio between a first combustion chamber (20) and a second combustion chamber (25) can be adjusted without changing the height of the housing (11).
