Abstract
(DE) Die Erfindung betrifft eine Airbaganordnung mit einem Gassack; mit einem Gasgenerator zum Aufblasen des Gassackes; mit einer innerhalb des Gassackes angeordneten flexiblen Kammer, in die das aus dem Gasgenerator ausströmende Gas eintritt und die mindestens eine Ausströmöffnung aufweist, durch die hindurch das Gas in den Gassack geleitet wird, um diesen aufzublasen; und mit mindestens einer Entlüftungsöffnung des Gassackes, durch die hindurch Gas aus dem Gassack in die Umgebung abströmen kann. Erfindungsgemäß ist die Entlüftungsöffnung (E) derart angeordnet, dass Gas aus der flexiblen Kammer (2) zu der Entlüftungsöffnung (E) gelangen kann, ohne die Ausströmöffnungen der flexiblen Kammer (2) zu passieren.
(EN) The invention relates to an airbag arrangement, comprising a gas bag, a gas generator for inflating the gas bag, a flexible chamber arranged within the gas bag, into which the gas from the gas generator flows, at least one outlet opening through which the gas is led into the gas bag in order to inflate the same and at least one ventilating opening, through which gas can escape into the environment. According to the invention, the ventilating opening (E) is arranged such that gas from the flexible chamber (2) can reach the ventilating opening (E) without passing through the outlet opening of the flexible chamber (2).
(FR) L'invention concerne un système d'airbag comprenant : un coussin de gaz ; un générateur de gaz servant à gonfler le coussin de gaz ; une chambre souple, située à l'intérieur du coussin de gaz, dans laquelle le gaz provenant du générateur de gaz pénètre, cette chambre comprenant au moins un orifice d'échappement par lequel le gaz peut être acheminé dans le coussin de gaz de façon à le gonfler ; ainsi qu'au moins un orifice de purge du coussin de gaz, par lequel le gaz peut sortir dudit coussin de gaz et se disperser à l'extérieur. L'invention se caractérise en ce que l'orifice de purge (E) est disposé de telle sorte que le gaz sortant de la chambre souple (2) puisse parvenir audit orifice de purge (E) sans passer par les orifices d'échappement de la chambre souple (2).
