A window air bag system comprises an air bag stored in a folded state along a structural member of a vehicle body and is designed to be inflated into the shape of a curtain in a lateral region of a passenger compartment by being supplied with gas, and a hollow energy-absorbing member disposed along a longitudinal direction of the structural member between the structural member and a garnish for covering the structural member so as to be contiguous to a position where the air bag is stored in a folded state. The pillar portion is an A-pillar or a C-pillar. A portion of the air bag stored is made from a base cloth having no inflatable portion, such that the portion is able to pass through a gap between the pillar and a pillar garnish easily and quickly so as to reduce the time required until completion of deployment of the air bag.
L'invention concerne un système d'airbag de toit, dans lequel un airbag (10), destiné à prendre la forme d'un rideau dans une zone latérale de l'habitacle par insufflation de gaz provenant d'un appareil de gonflage (22), est rangé en position pliée contre une partie de montant (32) et un brancard de pavillon (31). Un élément creux d'absorption d'énergie (51, 52) est placé dans le sens longitudinal de la partie de montant (32) et du brancard de pavillon (31), de façon à être contigu à une position dans laquelle l'airbag (10) est rangé en position pliée entre la partie du montant (32) et une garniture (42) du montant pour couvrir ladite partie du montant (32), et entre le brancard de pavillon (31) et une garniture (41) du brancard pour couvrir le brancard de pavillon (31). Le sens de déploiement de l'airbag (10) est ainsi stabilisé. La réduction du nombre de garnitures (42, 41) en saillie dans l'habitacle permet de garantir l'habitabilité pour les occupants, une bonne visibilité et une grande aisance d'accès au et hors du véhicule.
