Abstract: This invention relates to a side airbag device stored inside a vehicle seat and fixed to a side frame. The device includes an airbag that expands and deploys to restrict an occupant; an inflator that supplies expansion gas to the airbag; and a bracket connected to the side frame that holds the airbag and the inflator. The airbag includes a prepush chamber having an inflator stored therein and mainly deploys inside of the side frame; and a main chamber connected to the prepush chamber and mainly deploys forward of the side frame. The bracket includes a first surface oriented in the forward direction of the vehicle; and a second surface oriented to the inside of the seat in the width direction of the vehicle. When the airbag is stored by being folded and/or rolled, at least the main chamber is disposed on the first surface of the bracket.

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 provide a side airbag apparatus capable of quickly and properly restraining a passenger in the initial stage of deploying an airbag, along with a vehicle seat including this side airbag apparatus.[Resolution means] The airbag includes: a first chamber which is deployed towards the front of the side support part of the seat; a second chamber which starts being deployed inside the first chamber in the vehicle width direction prior to this first chamber; and a gas guide which is arranged in the first chamber so as to introduce the expansion gas (emitted from the inflator) into the second chamber. An internal vent hole, through which the expansion gas introduced by the gas guide flows into the second chamber, is formed at the boundary part between the first chamber and the second chamber. The second chamber includes: an upper region and a lower region; and an intermediate region disposed between the upper region and the lower region. In addition, at least one of the upper region or the lower region is configured to be deployed so as to protrude more to the front of the vehicle than the intermediate region.

Abstract: The airbag is provided with a main chamber that deploys toward the front of the vehicle and a pre-chamber that houses the inflator and begins to deploy ahead of the main chamber in the vehicle width direction to the inside of the main chamber. Here, the main chamber is demarcated into a front region and a rear region by a demarcation. The boundary area between the main chamber and the pre-chamber is provided with a front vent that directs the expanding gas from the pre-chamber to the pre-chamber front area and a rear vent that directs the gas to the rear region.

Abstract: A far side side airbag device provided on the side part in the center in the width direction of a backrest portion SB of either of separated seats arranged in the width direction of a vehicle, which restrains the movement of an occupant P. A cushion and an inflator expands and deploys the cushion. The cushion has a first portion and a second portion that expand and deploy onto the front surface of each of the adjacent separated seats when a signal is received to restrain the occupant and capture the side part of the occupant, and a center portion provided in between the first portion and the second portion. A protruding part is formed on the center portion in order to capture the head of the occupant.
