This invention is related to a hybrid gas generator (1) used in automobile safety to inflate a protective airbag, including, on the one hand, a body (2) containing an ignition device (16), and on the other hand, a reservoir (3) connected to the body and containing a pressurized gas (31) as well as initially closed discharge openings (10), characterised in that the body has; i) an initial pyrotechnic charge (14) intended to generate a quantity of gas which, coupled with the volume of gas (31) contained in the reservoir, allows the airbag to inflate in less than 50 milliseconds, ii) a second pyrotechnic charge (13) intended to generate, after the combustion of the initial pyrotechnic charge, a quantity of gas sufficient to keep the airbag inflated during several seconds.
La présente invention se rapporte à un générateur (1) de gaz hybride, utilisé en sécurité automobile pour gonfler un coussin de protection, comprenant d'une part un corps (2) contenant un dispositif d'allumage (16), et d'autre part, un réservoir (3) relié au corps et contenant un gaz (31) sous-pression ainsi que des orifices d'évacuation (10) initialement obturés, caractérisé en ce que le corps possède : i) un premier chargement pyrotechnique (14) apte à générer une quantité de gaz qui, couplée au volume de gaz (31) contenu dans le réservoir, permet de gonfler le coussin de protection dans une période de temps inférieure à 50 millisecondes, ii) un second chargement pyrotechnique (13) apte à générer, après la combustion du premier chargement pyrotechnique, une quantité de gaz suffisante pour maintenir le coussin de protection gonflé durant une période de temps de plusieurs secondes.
