Abstract

L'invention concerne un dispositif de remplissage d'un élément de retenue, notamment d'un airbag destiné à protéger les passagers d'un véhicule à moteur. Un réservoir sous pression (300) dans lequel est stocké un gaz inerte ou un mélange gazeux, présente au moins deux orifices de sortie (310, 320) fermés chacun par une membrane pouvant éclater (311, 321). Un module d'ouverture (100, 200) est affecté à chaque orifice de sortie (310, 320), le déclenchement de chaque module s'effectuant de façon indépendante.
