Abstract: A side airbag device includes an airbag 2 and an inflator. The airbag is formed in a bag shape by connecting peripheries of first and second main base cloths and of a vehicle inner side and a vehicle outer side. The airbag is partitioned into a front chamber and a rear chamber by a first partition wall. First inner tethers are provided in the front chamber and connect between a forward vehicle direction end of the front chamber and the first partition wall. Lengths of the first inner tethers and are shorter than a length between a first joint part connecting the first partition wall to the first inner tether and the forward vehicle direction end of the front chamber in the airbag in a front to rear vehicle direction before the airbag is deployed.

Abstract: Problem: To effectively suppress movement toward a collision site of an occupant even when the occupant is seated only in the driver's seat.
Resolution Means: a side airbag device 1 provided on a side surface portion on the center side in the width direction of the backrest SB of the seat s of one of the driver's seat Sd and the passenger seat Sn, and is provided with a cushion 2 that constrains movement of the occupant p toward a site where an impact is applied during a collision event. A portion of the inflator 3 is inserted into the cushion 2. The cushion 2 comprises a main chamber 2 a and a sub-chamber 2 b disposed on the base panel 4 b opposite the occupant side base panel 4 a of the main chamber 2 a that is seated by the occupant p seated in the driver seat Sd. Upon collision, when the occupant p seated in the driver's seat Sd moves toward the passenger seat side, the expanded sub-chamber 2 b interferes with the side support SS on the driver side of the passenger seat Sn, and the expanded main chamber 2 a is provided with the reaction force from the passenger seat Sn.

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).
