IGNITION COMPOSITIONS FOR INFLATOR GAS GENERATORS

摘要

Autoigniting compositions containing a hydrazine salt of 3-nitro-1, 2, 4-triazole-5-one for the gas generator of a vehicle occupant restraint system result in rapid autoignition at temperatures from approximately 150 DEG C (302 DEG F) to 220 DEG C (428 DEG F) thereby allowing the gas generator to operate at lower temperatures to facilitate use of an aluminium canister. The autoignition compositions of the present invention are relatively insensitive to shock or impact, are safe to manufacture and handle, and are advantageously classified as Class B materials.
