초록

High nitrogen nonazide gas compositions, useful in inflating passenger restraint gas inflator bags, comprise an amine salt of triazole or tetrazole fuel, and phase stabilized ammonium nitrate (PSAN) as an oxidizer. The combination of the amine azole salt and phase stabilized ammonium nitrate results in gas generants that are relatively more stable and less explosive, have improved ignitability and burn rates, and generate more gas and less solids than known gas generant compositions.

청구항

[ We claim:] [1.] A gas generant composition useful for inflating an automotive air bag passive restraint system comprising a mixture of:a high-nitrogen nonazide fuel selected from the class consisting of 1-, 3-, and 5-substituted amine salts of triazoles, and, 1- and 5-substituted amine salts of tetrazoles; and dry-mixed withan oxidizer selected from the group consisting of phase stabilized ammonium nitrate.
