Title (DE) KNIEGASSACKMODUL
(EN) KNEE AIRBAG MODULE
(FR) MODULE DE COUSSIN GONFLABLE POUR GENOUX
Abstract:
(DE) Ein Kniegassackmodul eines Fahrzeuginsassen-Rückhaltesystems hat ein Außengehäuse (14), in dem ein vor seiner Entfaltung zu einem Gassackpaket zusammengelegter Gassack (20) sowie ein Gasgenerator (16) aufgenommen sind, der Füllgas zum Befüllen des Gassacks (20) erzeugt. Im Außengehäuse (14) ist eine Austrittsöffnung (22) ausgebildet, durch die der Gassack (20) beim Entfalten das Außengehäuse (14) verlässt. Der Gassack (20) ist in mehrere, seriell angeordnete, in Strömungsverbindung stehende Kammern (28a - 28f) unterteilt. Die gasgeneratornächste Kammer (28a) ist von einer angrenzenden Kammer (28b) durch eine Wand (32) getrennt, die sich im aufgeblasenen Gassack (20) im Wesentlichen im Bereich der Austrittsöffnung (22) längs der Austrittsöffnung (22) erstreckt.
(EN) A knee airbag module of a vehicle occupant restraint system has an outer housing (14) in which an airbag (20), which before its deployment is folded up to form an airbag package, and a gas generator (16), which generates filling gas for filling the airbag (20), are accommodated. Formed in the outer housing (14) is an outlet opening (22) through which the airbag (20) upon deployment leaves the outer housing (14). The airbag (20) is divided into a plurality of serially arranged chambers (28a - 28f) which are connected in terms of flow. The chamber (28a) closest to the gas generator is separated from an adjacent chamber (28b) by a wall (32) which, in the inflated airbag (20) substantially in the region of the outlet opening (22), extends along the outlet opening (22).
(FR) Module de coussin gonflable pour genoux faisant partie d’un système de retenue pour occupants de véhicule, comprenant un boîtier extérieur (14) dans lequel sont logés un coussin gonflable (20), plié avant son déploiement pour former un ensemble coussin gonflable, et un générateur de gaz (16) qui génère le gaz de remplissage servant à remplir le coussin gonflable (20). Dans le boîtier extérieur (14) est ménagée une ouverture de sortie (22) à travers laquelle le coussin gonflable (20) sort du boîtier extérieur (14) lors de son déploiement. Le coussin gonflable (20) est divisé en plusieurs chambres (28a - 28f) qui se trouvent en communication fluidique et sont agencées de manière sérielle. La chambre (28a) la plus proche du générateur de gaz est séparée d’une chambre (28b) adjacente par une paroi (32) qui s’étend sensiblement dans la zone de l’ouverture de sortie (22) le long de cette dernière (22) lorsque le coussin gonflable (20) est gonflé.
