Gas generator with automatic firing function

Abstract

A gas generator for an air bag which includes a gas generating agent having an automatic igniting function is provided. Since a gas generating agent 9 b stored in a second combustion chamber 5 b has an automatic igniting function, the gas generating agent 9 b automatically ignites in case of a vehicle fire, which is accompanied by the combustion of the gas generating agent 9 a and the transfer charge 16 a and 16 b.
