Abstract

L'invention concerne un rideau de sécurité gonflable pour un véhicule comprenant : une unité de chambre principale ; une unité de chambre de rampe ; une unité d'introduction de gaz ; et un élément d'enveloppement. L'unité de chambre principale est stockée dans un état plié entre une doublure de tête et une carrosserie de véhicule d'un véhicule, et est déployée le long d'une surface latérale interne du véhicule en cas de collision de véhicule. L'unité de chambre de rampe est disposée dans un état plié conjointement avec l'unité de chambre principale et est formée pour communiquer avec la partie supérieure de l'unité de chambre principale de façon à gonfler entre la carrosserie du véhicule et le montant du véhicule pour empêcher le montant d'interférer avec l'unité de chambre principale. L'unité d'introduction de gaz est adjacente à l'unité de chambre de rampe et est conçue pour communiquer avec l'unité de chambre principale et l'unité de chambre de rampe. L'élément d'enveloppement est conçu pour être relié à une zone de non-gonflage qui divise l'unité de chambre de rampe et l'unité de chambre principale et, après que l'unité de chambre principale est pliée, envelopper une zone de l'unité de chambre principale pliée correspondant à l'unité de chambre de rampe de telle sorte que l'unité de chambre de rampe soit gonflée plus rapidement que l'unité de chambre principale lors d'un gonflage initial du rideau de sécurité gonflable. Ainsi, la présente invention peut empêcher le montant du véhicule d'interférer avec l'unité de chambre principale au moment du gonflage, et réduire le poids du dispositif de type rideau de sécurité gonflable.
