Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
80 words
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.
Claim 2
Independent Claim
80 words
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.
Claim 3
Dependent Claim
23 words
A method as recited in claim 1, further comprising compacting the unburned mixture of oxidizer, carbon material, and carbonate coolant with a binder.
Claim 4
Dependent Claim
18 words
A method as recited in claim 1, further comprising additionally cooling the produced gas after burning said mixture.
Claim 5
Independent Claim
76 words
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.

Claim 7
Dependent Claim
23 words
A method as recited in claim 4, including the step of compacting the unburned mixture of oxidizer and carbon material with a binder.
Claim 8
Dependent Claim
19 words
A method as recited in claim 4, including the step of cooling the produced gas after burning said mixture.
