    • A mixture of substances for the pyrotechnic generation of propellants for motor vehicle passenger protection devices consists of: (a) 10 to 50 wt % of a fuel selected from the acid dihydrazide group and (b) 50 to 90 wt % of an inorganic oxidiser selected from the group of nitrates and peroxides or their mixtures, in relation to the total weight of the mixture of fuel and oxidiser, and (c) possibly up to 30 wt % in relation to the total weight of the mixture, of a metal oxide and (d) possibly further additives or auxiliaries. The mixture of the invention is azide-free, consists of non-toxic components, is highly stable thermally and chemically, has an adequate rate of combustion and good ignitibility, where the combustion temperatures are markedly lower than those of prior art gas-generating mixtures, the quantity of gaseously generated fine dust particles is smaller, the combustion residues are easily filtrable, the propellant gas composition is essentially benign, the concentrations of noxious gases like CO and NOx in the propellant are as small as possible and the raw materials are particularly cheap.
    • (A)10至选自二酰肼的燃料和所选择的50重量%(B)50至90重量%的一种的%选自硝酸盐和:物质为烟火产生推进剂气体的用于机动车辆乘员保护装置,包括一种组合物 过氧化物或它们的混合物的无机氧化剂,在基于燃料和氧化剂,和(c)的混合物的总重量,每种情况下任选最多30重量%,基于混合物的总重量,金属氧化物和(d)任选的其它添加剂的 或赋形剂。 本发明的混合物是叠氮基的,无毒性的成分构成的,具有高的热稳定性和化学稳定性,容易加工和非吸湿性的,具有相对于已知的气体发生的混合物燃烧,以及良好的点火性,燃烧温度以足够的速率被显着降低,比重 产生较少的细颗粒灰尘气体,以及过滤的燃烧残渣被产生,推进剂组合物基本上是无害的,有害气体如CO,NOx的浓度是尽可能低的推进剂气体中和所述起始材料是特别便宜。
