Abstract

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.
