1. An apparatus comprising an inflatable vehicle occupant protection device and a gas generating composition which, when ignited, produces gas to inflate said inflatable vehicle occupant protection device, said gas generating composition comprising an inorganic salt oxidizer and a fuel, said fuel comprising 3-R1-6-R2-1,2,4,5-tetrazine-1,4, dioxide, wherein R1and R2are selected from the group consisting of hydrogen, amino, amino-nitrate, amino-nitramide, amino-oxalic acid, hydrazino, nitramino, tetrazolyl, 5-aminotetrazolyl, 5-aminotetrazolyl-nitrate, 2H-tetrazolyl-ammonium salt, hydrazinium-5-tetrazolyl, 5-amino-3-nitro-1H-1,2,4-triazol-1-yl, azido, carboxylic acid, and carboxylic acid amide. 2. The apparatus of claim 1 wherein the fuel is 3,6-diamino-1,2,4,5-tetrazine-1,4-dioxide. 3. The apparatus as defined in claim 1 wherein the inorganic salt oxidizer is selected from the group consisting of ammonium nitrate, potassium nitrate, potassium perchlorate, ammonium perchlorate, and combinations thereof. 4. The apparatus as defined in claim 3 wherein the oxidizer is ammonium nitrate and the ammonium nitrate is phase stabilized. 5. The apparatus of claim 1 wherein the gas generating composition further comprises about 10% to about 25% by weight based on the weight of the gas generating composition of a coolant. 6. The apparatus of claim 5 wherein the coolant is aluminum oxide. 7. The apparatus of claim 1 wherein the amount of fuel is about 30% to about 70% by weight based on the combined weight of the inorganic salt oxidizer and the hydrogen containing fuel. 8. The apparatus of claim 1 wherein the amount of inorganic salt oxidizer is about 30% to about 70% by weight of the combined weight of the fuel and the inorganic salt oxidizer.
