Abstract
(EN)
To prevent the lower side of an airbag from riding up over the thigh of an occupant during inflation and deployment of the airbag. Also, to suppress displacement in the vertical direction or the longitudinal direction and to more reliably perform inflation and deployment to a prescribed position during inflation and deployment of the airbag. The present invention is a side airbag device 11 installed to the side of a backrest SB of a vehicle seat. The present invention comprises: an airbag 12; and an inflator 13 provided inside the airbag 12, the inflator 13 receiving an output signal from a sensor and supplying gas to the airbag 12, which is in a folded state. The airbag 12 has: a first protection part that protects at least the stomach part Pab of an occupant P from above; and a second protection part that protects the hips Phi of the occupant P. A vertical-direction intermediate portion of a base fabric panel 14a that forms the airbag 12 on the side contacting the occupant P has an anti-slip portion having a friction coefficient greater than that of the surface of the base fabric panel 14a, the vertical-direction intermediate portion being located within a lower region of the airbag 12 that includes the second protection part.

La présente invention vise à empêcher le côté inférieur d'un coussin de sécurité gonflable de monter sur la cuisse d'un occupant pendant le gonflage et le déploiement du coussin de sécurité gonflable. De même, la présente invention vise à supprimer le déplacement dans la direction verticale ou dans la direction longitudinale et à effectuer de manière plus fiable le gonflage et le déploiement à une position prescrite pendant le gonflage et le déploiement du coussin de sécurité gonflable. La présente invention porte sur un dispositif de coussin de sécurité gonflable latéral (11) installé sur le côté d'un dossier (SB) d'un siège de véhicule. La présente invention comprend : un coussin de sécurité gonflable (12); et un dispositif de gonflage (13) disposé à l'intérieur du coussin de sécurité gonflable (12), le dispositif de gonflage (13) recevant un signal de sortie en provenance d'un capteur et fournissant du gaz au coussin de sécurité gonflable (12), qui est dans un état plié. Le coussin de sécurité gonflable (12) comprend : une première partie de protection qui protège au moins la partie ventrale (Pab) d'un occupant (P) depuis le dessus; et une seconde partie de protection qui protège les hanches (Phi) de l'occupant (P). Une partie intermédiaire dans la direction verticale d'un panneau de tissu de base (14a) qui forme le coussin de sécurité gonflable (12) sur le côté en contact avec l'occupant (P), comporte une partie antidérapante ayant un coefficient de frottement supérieur à celui de la surface du panneau de tissu de base (14a), la partie intermédiaire dans la direction verticale étant située à l'intérieur d'une région inférieure du coussin de sécurité gonflable (12) qui comprend la seconde partie de protection.
