Abstract

A chemical gas generant mixture of carbon, an oxidizer which does not contain hydrogen and, optionally, a carbonate or other coolant.

Claims

1. A method of supplying generated gas to expand an inflatable safety restraint without the production of substantial water vapor during gas generation, comprising the steps of:

a. preparing a mixture consisting essentially of;

1. an oxidizer which does not contain hydrogen, said oxidizer being selected from the group consisting of metal chlorates and perchlorates;

2. a carbon material;

3. a carbonate coolant;

b. burning said mixture to produce a gas; and

c. directing the gas into the inflatable safety restraint.

2. A method as recited in claim 1, further comprising compacting the unburned mixture of oxidizer, carbon material, and carbonate coolant with a binder.

3. A method as recited in claim 1, further comprising additionally cooling the produced gas after burning said mixture.

4. A method of supplying generated gas to expand an inflatable safety restraint without the production of substantial water vapor during gas generation, comprising the steps of:

a. preparing a mixture consisting essentially of;

1. an oxidizer which does not contain hydrogen, said oxidizer being selected from the group consisting of metal chlorates and perchlorates;

2. a carbon material;

b. burning said mixture to produce a gas; and

c. directing the gas into the inflatable safety restraint.

5. A method as recited in claim 4, including the step of compacting the unburned mixture of oxidizer and carbon material with a binder.

6. A method as recited in claim 4, including the step of cooling the produced gas after burning said mixture.
