The invention relates to a hybrid gas generator intended for motor vehicle safety.The generator (1) includes a container (2) containing a cold gas (10) under pressure and having an open end in which a compartment (2), which is located outside the container (2), is fixed. This compartment (3) is provided with gas discharge orifices (6) and has a front wall (8) in which there is an opening closed by a diaphragm (9) which makes it possible to separate the inside of the container (2) from the inside of the compartment (3), in a leaktight fashion. The latter contains an initiator (12) with shaped explosive charge and a pyrotechnic charge (13), the initiator (12) being capable of destroying the diaphragm (9) from a distance and of initiating the pyrotechnic charge (13).This generator (1) makes it possible to initiate deployment of the airbag using cold gas (10) as soon as it starts to operate.
