摘要： A gas generating agent for air bags which has desirable properties such as the ability to generate a significantly large amount of gas, a low combustion temperature, etc.; and semicarbazide-metal complexes usable as the base of the agent. The agent contains as the active ingredient at least one base selected among semicarbazide-metal complexes represented by the general formula: [M(X)1](NO3)m(OH)n wherein M represents Mg, Al, Ca, Mn, Cu, Zn, or Fe; X represents H2NNHCONH2; 1 is 2 or 3; m is an integer of 1 to 3; and n is an integer of 0 to 2, provided that (m+n) is equal to the ionic valance of the metal represented by M.

摘要： An air bag gas generating agent which can markedly reduce the concentration of toxic components, particularly both CO and NOx, in the aftergas, while maintaining various favorable properties of non-azide gas generating agents. The agent is of non-azide type and contains a nitrogen-containing organic compound and an oxidizing agent as the active ingredients and at least one metal oxide selected among molybdenum oxide, tungsten oxide, and metal oxides having a BET specific surface area of not less than 5 m /g as the combustion catalyst.

摘要： A manganese complex represented by the formula (1): [Mn(H2NNHCONH2)3](NO3)2 which has a weight loss of at most 1 % after being heated at 107 DEG C for 400 hr. The manganese complex possesses an excellent heat stability and can be used as an active ingredient of a gas generator for an air bag. The gas generator contains the above manganese complex. When the manganese complex is incorporated in the form of a complex mixture thereof with a semicarbazide and/or a carbohydrazide into the gas generator, the gas generator has such a characteristic that the content of the combustion residue in an inflator is high.

摘要： A gas generator for air bags comprising (1) biscarbamoylhydrazine as a base of the generator, (2) a salt of oxoacid of halogen as an oxidizing agent, (3) a nitrate as another oxidizing agent, and (4) a combustion catalyst as the active ingredients. This generator has a proper combustion performance and a low combustion temperature, generates a gas lowered in the content of toxic components such as CO and NOx and that of emitted suspended particles, is excellent in heat stability, and is preferably far superior to azide and non-azide gas generators of prior art in safeness.

摘要： A gas generating agent for air bags, which has such favorable characteritics as moderate combustion performances, a low combustion temperature, a reduced content of toxic components, such as CO and NOx, in the gas formed by the combustion, and a higher safety than that of conventional azide-based gas generating agents. The agent comprises at least one gas generating base selected among urazole and metal salts thereof and an oxidizing agent as the active ingredients.
