ABSTRACT:
Pyrotechnic gas generator utilizable particularly on a motor vehicle for operating safety devices, such as safety belt retractors.
The generator comprises a resistant body containing an ignition bead (5) and a gas generating charge (3). In order to obtain very short operating times while offering maximum safety and reliability, the gas generating charge is separated from the ignition bead by a dielectric hood (6) which forms a leak-tight initiation chamber (7) around the ignition bead, the gas generating charge being composed of grains of powder based on nitrocellulose and a pulverulent oxyreduction powder containing at least one metal.
