    Abstract: An anhydrous 5-aminotetrazole or “5-AT” based gas generating composition for use in passive restraint devices, such as air bags and a method of preparing the same that is devoid of metal oxides. The gas generating composition includes 5-AT with a blend of oxidizers such as potassium perchlorate and potassium nitrate. This gas generating composition is devoid of metal oxides, such as copper oxide or iron oxide, which form an insoluble slag when ignited. After ignition, the combustion products of the gas generating composition can be filtered with a filter assembly that includes a ceramic blanket. The ceramic blanket preferably includes an aluminum oxide and a silicon oxide.

    Abstract: Preferred gas generant compositions incorporate a combination of 5-aminotetrazole nitrate and an oxidizer. The oxidizer may be selected from a group including nonmetal and metal nitrates, nitrites, chlorates, chlorites, perchlorates, and oxides. 5-aminotetrazole nitrate is characterized as an oxygen-rich fuel and is therefore considered to be a self-deflagrating fuel. To tailor the oxygen balance in certain applications, however, the use of an oxidizer is preferred. These compositions are especially suitable for inflating air bags and actuating seatbelt pretensioners in passenger-restraint devices.

    Abstract: A gas generant is provided which decreases toxic components, in particular carbon monoxide and nitrogen oxides, in generated gas to a concentration practical as an air bag system for automobile. A nitrogen-containing organic compound such as a compound containing amino group or amido group or a tetrazole derivative and a oxygen-containing inorganic oxidizer such as KNO3, Sr(NO3)2 or KClO4 are essential components. Therewith one or more metal oxides are contained in the mixed catalyst of the gas generant composition. The oxide is selected from manganese dioxide having a specific surface area not less than 50 m2/g; copper oxide having a specific surface area not less than 1 m2/g; molybdenum oxides such as molybdenum dioxide, molybdenum trioxide, molybdic acid and ammonium molybdate: and copper oxides, cobalt oxides, iron oxides and silver oxides.
