Abstract
A pyrotechnic gas generator with adaptable flow rate for air bags including a hollow body in which a sealing partition (9) defines two separate combustion chambers (1a, 1b) each containing a different gas-generating pyrotechnic charge (2a, 2b). An initiator (3) with two heads (4, 5) and a single power supply ignites each of the two charges at different times. The two heads (4, 5) may be provided with separate different resistors (R1, R2) or incorporated into a switching bridge including four switches combined with a diode circuit. The generator (10) is useful for making a gradual generator for an air bag for protecting the driver of a motor vehicle.
