ABSTRACT:
A pyrotechnic gas generator for motor-vehicle safety in the form of a one-piece cylindrical body (1) which comprises a side wall (2) and a transverse wall (3) which divides the body (1) into an upstream compartment (4) and a downstream compartment (5). These compartments (4, 5) each contain a pyrotechnic charge (6, 7) and an ignition system (15, 16). A lid (30) and a can (31) are fixed to the external side wall (2) and constitute a diffusion chamber. A safety unit (26) grips part of the side wall (2) and makes it possible, depending on the electrical signals received by the generator (100), either to inflate the airbag partially or to inflate the airbag completely with the possibility of modulating the rate of inflation.
