The airbag is housed in the retainer and includes a proximal end-side folded portion folded in a roll shape or a bellows shape, an intermediate-side folded portion extending from the proximal end-side folded portion and folded above the proximal end-side folded portion, and a distal end-side folded portion extending from the intermediate-side folded portion and folded in a roll or bellows shape in a cross section in a vehicle side view. The intermediate-side folded portion has a plurality of folding-back points at which folding is made along the distal end-side folded portion in a front-rear direction of the distal end-side folded.

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 deviceprovided 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 cushionthat constrains movement of the occupant p toward a site where an impact is applied during a collision event. A portion of the inflatoris inserted into the cushion. The cushioncomprises a main chamberand a sub-chamberdisposed on the base panelopposite the occupant side base panelof the main chamberthat 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-chamberinterferes with the side support SS on the driver side of the passenger seat Sn, and the expanded main chamberis provided with the reaction force from the passenger seat Sn.

Side airbag device

To realize disposition of a retainer that can improve an occupant comfort of a passenger of a saddled vehicle. In a saddled vehicle including: a vehicle body including a head pipe that supports a steering system and a down frame that extends downward from the head pipe; a retainer provided behind the head pipe; an inflator; and an airbag accommodated in the retainer, the airbag being configured to be expanded by gas released by the inflator and deployed in front of the passenger, the retainer is provided with a fastening portion that fastens the retainer to the vehicle body, and the fastening portion includes a plurality of fastening members.

To effectively retain a deployed airbag without increasing installation man hours, in addition to suppressing rotation of this airbag in a direction away from a seat. For example, a side airbag apparatusinstalled inside a backrest SB of the seat S includes: an airbag; an inflatorprovided inside the airbag; a tether; and a bracket. The airbagis deployed in a first direction in which a base end sidethereof is attached to a seat back frame SBF and the tip side thereof is distant from the backrest SB. The tetherincludes: one endattached to the seat back frame SBF; and the other end which extends in the first direction on the outer surface of the airbagin the deployed state so as to be attached to the part on the tip sideof the airbag. A bracketis attached to the seat back frame SBF and provided in the direction in which the tetherextends. The tetheris supported by the front end of the bracket

Airbag apparatus

A saddle riding vehicle airbag device can be disposed compactly and the airbag can be deployed vertically upward. In the saddle riding vehicle airbag device provided with a retainer that is provided in front of a seat for a rider, an inflator and an airbag that is housed in the retainer, is inflated by means of a gas discharged from the inflator and is deployed in front of the rider, in which the retainer is provided with an L-shaped airbag passage that causes the airbag to deploy upward in a left-right direction, and, in a deployed state, the airbag is formed bilaterally asymmetrical with respect to a left-right center line of the airbag.

Saddle riding vehicle airbag device

Problem: To provide a side airbag apparatus which can prevent the deterioration of the neck damage value of a passenger during a side collision or sufficiently protect the waist of the passenger. Resolution Means: A side airbag apparatusinstalled in a vehicle, including: a bag shaped cushionwhich is housed in a seat backof a vehicle seatand expanded and deployed on the side of the vehicle seat utilizing gas supplied from an inflator; and a holding partfor retaining the shape in the housed state of the cushion, wherein the cushion is wound or folded in a long shape in the vertical direction of the vehicle and housed in the seat back in the shape with the upper partthereof further folded back to the anterior of the vehicle, and wherein the holding part retains the upper part or lower part of the cushion which is folded back to the anterior of the vehicle.

Side airbag apparatus

A side airbag device includes an airbagand 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.
