Title
(DE) SCHUTZVORRICHTUNG MIT EINEM NACH AUFBLASEN EIGENSTEIFEN GASSACK
(EN) PROTECTIVE DEVICE WITH AN AIRBAG WHICH IS INTRINSICALLY RIGID AFTER INFLATION
(FR) DISPOSITIF DE PROTECTION POURVU D'UN SAC A AIR COMPRIME A RIGIDITE INTRINSEQUE APRES GONFLAGE
Abstract
(DE) Eine Schutzvorrichtung gegen Seitenaufprall in Kraftfahrzeugen mit einem aufblasbaren, zur Herstellung einer Eigensteifigkeit in dem Gassackgewebe fixierte Versteifungselemente aufweisenden und aus mehreren Kammern bestehenden Gassack, soll eine ausreichende Eigensteifigkeit des aufgeblasenen Gassackes gewährleisten. Hierzu ist vorgesehen, dass die Versteifungselemente als auf einer Seite der jeweiligen Gassackkammern (15) angebrachte, flächig ausgebildete Abstützelemente (16) ausgebildet sind, die beim Aufblasen des Gassackes (14) in eine die Biegesteifigkeit des aufgeblasenen Gassackes (14) erhöhende Form gebracht werden.
(EN) The invention relates to a protective device for providing protection against a side impact in a motor vehicle, comprising an inflatable airbag which has stiffening elements that are fixed in the airbag fabric, for producing intrinsic rigidity, and which consists of several chambers. The aim of the invention is to guarantee an adequate degree of rigidity of the airbag. To this end, the stiffening elements are configured in the form of flat support elements (16) that are mounted on one side of the chambers (15) of the airbag, respectively. When the airbag (14) is inflated, these support elements adopt a shape in which they increase the resistance of the airbag (14) to bending.
(FR) L'invention concerne un dispositif de protection contre les collisions latérales dans des véhicules automobiles, comprenant un sac à air comprimé gonflable, constitué de plusieurs chambres et présentant des éléments de renforcement fixés dans le tissu du sac et servant à produire une rigidité intrinsèque. L'invention vise à garantir une rigidité intrinsèque suffisante du sac à air comprimé gonflé. A cet effet, les éléments de renforcement sont réalisés sous forme d'éléments d'appui (16) plans, appliqués sur un côté des chambres (15) du sac à air comprimé et prenant, en cas de gonflage du sac à air comprimé (14), une forme augmentant la rigidité à la flexion du sac à air comprimé gonflé (14).
