Abstract
The present invention relates to a hybrid gas generator (1), used for motor vehicle safety to inflate an airbag, comprising a body (2) containing an ignition device (16) and a reservoir (3) connected to the body and containing a pressurized gas (31), together with initially closed-off discharge orifices (10). The body possesses a first pyrotechnic charge (14) capable of generating a quantity of gas which, coupled to the volume of gas (31) contained in the reservoir, allows the airbag to be inflated in a time period of less than 50 milliseconds, and a second pyrotechnic charge (13) capable of generating, after combustion of the first pyrotechnic charge, a quantity of gas sufficient to keep the airbag inflated for a time period of several seconds.
