Abstract: The present invention is a side airbag device stowed in a side support part of a vehicle seat, which includes: an airbag capable of expanding and deploying toward a front side from the side support part; an inflator that supplies expansion gas to the airbag; and a bracket that retains the airbag in a compressed state. The inflator is secured to an inner side (occupant side) of a side frame of the vehicle seat. Furthermore, the bracket has a rear region that covers a rear side of the airbag in a compressed state and an inner region that extends continuously forward from the rear region between an inner side of the airbag and a seat pad.

Abstract: The present invention is provided with an inflator arranged on the occupant side of the side frame positioned on the side portion inside the seatback that generates expansion gas and an airbag that is expanded by the expansion gas and protects an occupant seated on the vehicle seat. The airbag includes a main chamber that deploys toward the front of the seatback, and a pre-chamber that houses the inflator inside and is connected to the occupant side of the main chamber. In addition, an internal tether having a front end part connected to the front portion of the pre-chamber and a rear end part connected to the rear portion of the pre-chamber are provided inside the pre-chamber.

Abstract: A side airbag device that is stowed inside a vehicle seat and protects an occupant seated in the seat, including an airbag that restrains the occupant by expanding and deploying, and an inflator that supplies expansion gas to the airbag. The airbag includes a pre-push chamber that contains the inflator inside and deploys mainly on the occupant side (inside), and a main chamber that is connected to the pre-push chamber and deploys mainly toward the front of the vehicle. When the airbag is in the stowed state, the pre-push chamber forms the first folded part and the main chamber forms the second folded part. At the portion where the first folded part and the second folded part overlap, a sewn part joins the first folded part and at least a portion of the pre-chamber, and the sewn part is configured to break during deployment of the airbag.

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 passenger protection apparatus including this.
[Resolution means] A side airbag apparatus according to the present invention includes: an airbag for restraining a passenger when expanded and deployed; and an inflator for supplying expansion gas to the airbag. The airbag includes: a first chamber which houses the inflator and is deployed outside in the vehicle width direction of the frame side wall part; and a second chamber which is deployed inside in the vehicle width direction of the frame side wall part. In addition, the first chamber is deployed such that at least a portion thereof, as seen from the vehicle side, overlaps the frame side wall part. At this time, the rear end part of an expanding region of the second chamber, as seen from the vehicle side, is formed in front of the rear end part of the first chamber.

Abstract: [Problem]
To provide: a side airbag device capable of quickly and properly restraining a passenger in the initial stage of deploying an airbag; and a vehicle seat provided with the side airbag device.
[Resolution Means]
A side airbag device is provided with: an airbag disposed inside a side supporting part of a seat, that restrains an occupant by expanding and deploying in the event of a vehicle collision; and an inflator that supplies an expansion gas to the airbag. Furthermore, the airbag is folded and stored in the side supporting part in an extended condition such that the vertical direction is the longitudinal direction.
