Abstract:
Hybrid gas generator unit used for motor vehicle safety to inflate at least one side airbag, which comprises:a flexible element containing a pyrotechnic charge and possessing an upstream end and a downstream end; a reservoir of pressurized gas, said reservoir having an upstream end and a downstream end; and an electropyrotechnic igniter housed in a body near the upstream end of the flexible element and the downstream end of the reservoir; the said igniter being capable during operation, of initiating the combustion of the pyrotechnic charge contained in the flexible element and, of causing the pressurized gas contained in the reservoir to be released, wherein the gas generator unit is designed so that, after combustion of the pyrotechnic charge, the pressurized gas escapes firstly from the reservoir in order to pass through the body and then sets off in the opposite direction to pass through the flexible element.
