Abstract
A generator includes a tubular casing sealed by a bottom, with a wall crossed by discharge orifices. The generator further includes an adapter sleeve retained in the tubular casing by crimping, a pyrotechnic initiator, and a tubular filter covering the discharge orifices. A pyrotechnic charge is inserted between the adapter sleeve and the bottom. A charge securing arrangement includes, on the bottom side, a transverse partition, and on the open side, an open-worked washer urged towards the bottom. A sealing member is capable of breaking during combustion of the charge, to thereby allow the gases to escape out of the casing via the filter and the discharge orifices. After failure of the sealing member, the space occupied by the pyrotechnic charge is delimited axially by the open-worked washer and the bottom.
