Abstract: A cover member (18) is formed of a pliable fabric material having a plurality of polymer fibers, and is configured to maintain the shape of the airbag by mutual fusion of at least part of the polymer fibers. The cover member (18) is configured to have a high stiffness portion (25) of higher stiffness than other portions of the cover member, as a result of partial overlaying of the pliable fabric material in more folds than at other portions.

Abstract: A side airbag device for restraining an occupant at an initial stage of airbag deployment. A seatback includes a side support portion that bulges out in a vehicle advancement direction on a vehicle width direction side portion. A side frame having a frame side wall that extends in the vehicle advancement direction when a horizontal section is disposed in the interior of the side support portion. The side airbag device is housed on a vehicle width direction inner side of the frame side wall. An inflator is provided on the vehicle width direction inner side of the frame side wall to supply inflation gas to the airbag. An internal vent hole through which the inflation gas flows from a sub-chamber into a main chamber is provided in a partition between the main chamber and the sub-chamber. The sub-chamber deploys so as to overlap the frame side wall when seen from the side of the vehicle. The main chamber deploys without overlapping the frame side wall when seen from the side of the vehicle.

Abstract: A curtain airbag device that allows easy recognition and correction of twisting of an airbag during attaching. The curtain airbag device can be stored in a compact manner during transportation. The curtain airbag device including an airbag that is disposed along a roof side rail of a vehicle interior, and that can deploy so as to cover a window portion on a side face of the vehicle interior, the curtain airbag device further including a cover that covers the airbag, at least, in a part of the folded or rolled airbag in the longitudinal direction. The cover is formed of a pliable fabric material of polymer fibers, and maintains the shape of the rolled-up airbag through mutual fusion of at least a part of the polymer fibers. A high stiffness portion harder than other portions and formed during the fusion of the cover is provided in the cover extending in the longitudinal direction of the cover.

Abstract: An airbag apparatus capable of protecting an occupant by restraining movement of the occupant in an obliquely forward direction and towards a far side during a collision. A far side airbag apparatus (102), which is an airbag apparatus, deploys between a driver seat (106) and a front passenger seat (108) arranged side by side in a vehicle width direction of a vehicle cabin (100). The apparatus (102) includes a cushion (120) which is embedded in a floor of the vehicle cabin (100) and reaches a height at least equal to that of a pelvis region (160) of an occupant (156) seated in either one of the driver seat (106) and the front passenger seat (108) during inflation and deployment.

Abstract: A side airbag device 100 includes: a main bag 120, is built in a seat of a vehicle, and inflates and deploys toward a side of an occupant and a vehicle front side; an inner bag 122 which is formed in a bag shape independent of the main bag 120, and inflates and deploys on a vehicle rear side inside the main bag 120. An inflator 110 provided inside the inner bag 122 to supply gas; and a tension member 126 which spans between the vehicle front side and the vehicle rear side inside the inner bag 122 and is tensioned as the inner bag 122 inflates and deploys. The length of the inner bag 122 in the front-back direction of the vehicle at inflation is restricted by the tension member 126 to a predetermined range, and the inner bag therefore inflates in a vehicle width direction and pushes and spreads the vehicle rear side of the main bag 120 from the inside of the main bag 120 to both sides in the vehicle width direction.
