摘要:
An azide-free gas-generating composition for use in gas generators for safety arrangements, in particular in gas generators for vehicle occupant restraint systems, includes a fuel and an oxidizer. The fuel is a compound having a melting point of at least 120 degrees C., and is selected from the group of nitrogenous organic compounds and of aliphatic dicarboxylic acids, and mixtures, derivatives and salts thereof. The oxidizer comprises tetrakis(2,2,2-trinitroethyl)orthocarbonate (TNEOC), with the TNEOC being present in a proportion of at least 10% by weight of the composition.
摘要:
A method for inflating a gas bag of a safety arrangement in vehicles provides a gas generator which contains a pyrotechnic propellant comprising an organic fuel and ammonium perchlorate as an oxidizing agent. The pyrotechnic propellant, after its activation, releases a gas which has an amount of hydrochloric acid. A coating is arranged on the inner surface of the gas bag, on which the hydrochloric acid is neutralized or absorbed.
摘要:
A gas-generating composition is adapted for use in safety devices for vehicles. The composition essentially of 20 to 25% by weight of an organic fuel, 30 to 60% by weight ammonium perchlorate, 5 to 30% by weight of a chloride scavenger and conventional processing aids in a proportion of 0 to 10% by weight. An iron compound is used as said chloride scavenger, which is converted into gaseous iron(III)-chloride upon reaction of the composition.
摘要:
A pyrotechnic composition, in particular for use in safety devices for motor vehicles, has an auto-ignition temperature between 140 and 180 degrees C., and comprises at least 3-nitro-1,2,4-triazol-5-one (NTO) in a proportion of 20 to 60% by weight. The NTO is stabilized by at least one of the following measures: (a) the NTO has an average grain size of 200 to 600 □m; and (b) the composition comprises an oil in an effective quantity for stabilizing the NTO. The pyrotechnic composition is adapted for use in a safety device, in particular in a safety device in motor vehicles.
