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: A side airbag (2), for mounting to a seat frame (7) having a support surface (7a) facing a vehicle door. An inflator (6) is stored inside the side airbag near a rear end in a deployment and inflation direction. The side airbag has a folded portion (X1) with a folding line (F1) and a superposed portion (S) sequentially from the side of the inflator to a front end thereof in the deployment and inflation direction. The folded portion has an abutment portion (Q) folded back to a vehicle rear side from a vehicle front side on a front side of the inflator in a vehicle front-back direction along the folding line and abutted against the support surface. The superposed portion is formed in a rolled and superposed state, and the folded portion is arranged between the support surface and the superposed portion in the vehicle-widthwise
