Abstract
A pyrotechnic gas generator for driving an actuator includes a body defining a combustion chamber housing a main pyrotechnic charge, and an ignitor for initiating combustion of the main pyrotechnic charge. The pyrotechnic gas generator includes at least one delay chamber adapted to communicate with the combustion chamber via at least one inlet orifice, and the delay chamber is provided with at least one outlet orifice for passing gas out from the gas generator. The at least one outlet orifice is provided with a seal adapted to pass from a closed state to an open state when the pressure inside the delay chamber reaches a rupture limit pressure.
