Abstract
The invention relates to an igniter composition for use in a gas generator for a safety means in vehicles. The igniter composition consists of a gas-generating composition in an amount of 15 to 70 wt-% and of a thermite composition in an amount of 30 to 85 wt-%. The gas-generating composition consists essentially of a guanidine compound as fuel and an inorganic oxidizer. The thermite composition consisting essentially of a metal and a metal oxide. The igniter composition or the gas-generating composition and the thermite composition, each for itself, have an oxygen balance of between 0 and −20%.
