Abstract: A vehicle airbag device and a method for manufacturing the same, in which stud bolts for securing the device to the vehicle body can be inserted avoiding the sewn sections, and in which unbalanced stresses are not generated in the panel parts during expansion and deployment.
The device having a pair of panel parts, a pair of expansion parts integrally provided on the pair of panel parts, the expansion part of the first panel part overlapping the second panel part, and the expansion part of the second panel part overlapping the first panel part, forming an overlapping section by joining each expansion part to each panel part at a sewn section, and joining the overlapping section with a pair of panel part outer edges, the outer sewn section forming a hollow bag body, and providing inflator insertion holes and bolt insertion holes provided through the overlapping section.

Abstract: A side airbag device includes a seat frame that is along a side surface of a seatback of a seat and is built in the seatback, an inflator that is attached to an occupant side of the seat frame, and a cushion that receives a gas from the inflator so as to be expanded and deployed. The cushion includes an inner side expansion part that is stored at the occupant side of the seat frame and is connected to the inflator, and an outer side expansion part that is continuously provided with the inner side expansion part, that is stored at an opposite side of the seat frame with respect to the occupant side, and that receives the gas from the inner side expansion part so as to be expanded and deployed.

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.
