Abstract
A pyrotechnic gas generator (1) for airbags comprising housing (2) which has a side wall (3) closed at its two ends. A traverse plate (6) divides the housing (2) into an upstream part (9) and a downstream part (10). The upstream part (9) contains a tube (16) which seperates, in a gas-tight manner, two combustion chambers (17, 18), each one provided with a pyrotechnic charge (19, 20). An electrical ignition device (5) consists of an initiator with two heads (21, 22) may be incorporated in a switching bridge having four switches linked to a circuit with diodes. Thus, it is possible either to initiate only a single head (21, 22) as required, or to initiate both heads in a programmed time-staggered manner.
