Air bag inflator using liquid monopropellant and adaptable to produce outputs with various parameters
First Claim
1. A gas generator to provide gases under pressure for inflating an air bag, comprising:
- a wall forming a combustion chamber, said wall including a burst portion which fractures upon the exertion of a sufficient charge in said combustion chamber;
an initiator inside said combustion chamber for initiating the combustion of a charge contained in said combustion chamber;
an auxiliary chamber;
a conduit connecting said chambers; and
a fluid gas-generating charge contained in said chambers, said charge being auto-ignitable by said initiator, and whose reaction is self-sustaining after ignition.

Abstract
A gas generator to provide gases under pressure for an air bag. A combustion chamber and an auxiliary chamber contain a fluid gas-generating charge which is auto-ignitable. The combustion chamber has a burst portion which bursts after ignition, and the generated gases flow from it to the air bag. A conduit interconnects the two chambers. For a low pressure/high temperature regime the conduit acts as a flame suppressor to prevent flame from entering the auxiliary chamber so combustion can occur in the auxiliary chamber. For a high pressure/low temperature regime the conduit is a nozzle which passes the flame. Combustion then occurs in both of the chambers.
