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.

Abstract: A side air bag device restraining an occupant at the early stage of the deployment. A seat back has a side support part bulging in a vehicle forward direction at a side part in a vehicle width direction. A seat frame of the seat is provided inside the seat. The side air bag device has an air bag deploying to restrain an occupant and an inflator supplying inflating gas. A side frame part of the seat frame is inside the side support part, and the side air bag device is on an outer side of the side frame. The air bag has a main chamber deploying forward and to an outer side of the side support part and a sub-chamber deploying inside the side support part. The sub-chamber deploys further toward a forward side than a vehicle forward edge of the side frame, at least a front part of the side support part protrudes and deforms toward an occupant side.

Abstract: A side airbag apparatus which allows a reduced amount of base fabric and, enables gas to flow efficiently inside the cushion. An inflator (110) supplies gas, a cushion (104) in which base fabrics are formed into a bag shape and inflates and deploys to protect an occupant (118) during a vehicle emergency, a base fabric joint portion (120) which is provided to join main panels 108a and 108b of the cushion (104) in a linear manner and partitions the cushion (104) into a rear chamber (114), a front chamber (116), and an opening (123) provided midway along the base fabric joint portion (120). The base fabric joint portion (120) includes vent forming portions 125a and 125b arranged in two rows which extend from both ends of the opening (123) towards the front chamber (116) or rear chamber (114) and form a projecting vent (124). The projecting vent (124) permits flow of gas between the rear chamber (114) and the front chamber (116).

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.
