Hybrid inflator including non-metallic nitrogen containing ignitable material
First Claim
1. An apparatus for use in inflating a vehicle occupant restraint, said apparatus comprising:
- a container for holding a supply of gas;
a gas in said container, said gas comprising an inert gas and an oxidizer gas;
a quantity of a non-metallic nitrogen containing compound in said container which burns in the presence of said oxidizer gas which generates combustion products including heat for heating said inert gas, said oxidizer gas helping to support the combustion of said quantity of non-metallic nitrogen containing compound;
igniter means for igniting said quantity of non-metallic nitrogen containing compound; and
means for directing said inert gas as heated by said combustion products toward the vehicle occupant restraint;
said quantity of non-metallic nitrogen containing compound being in an intimate mixture with a binder material comprising a polyether polyester polymer and said nitrogen containing compound is present in a respective weight ratio to said binder material of about 20;
1 to about 5;

Abstract
An apparatus (10) for inflating an air bag includes a container (12) having a chamber (16) for holding a noble gas and an oxidizer gas under pressure. A body (20) of an ignitable material comprising a non-metallic nitrogen containing compound is disposed in the container (12). Upon ignition of the body (20) of ignitable material, combustion products, including heat, are generated. The combustion products then mix with, and heat, the noble gas and the oxidizer gas. The body (20) of ignitable material undergoes further combustion upon exposure to the oxidizer gas to yield an inflation fluid comprising the noble gas and any unreacted oxidizer gas. The inflation fluid flows from the container (12) through openings (28) in the end wall of the container (12) into a diffuser (36). The inflation fluid exits the diffuser (36) and inflates an air bag connected with the diffuser (36).
