Abstract: [Problem] To enable an airbag module to be assuredly assembled to a cored bar.
[Resolution Means] The present invention is applied to a steering wheel including: a cored bar member; and an airbag module which houses an airbag cushion and an inflator and is coupled to the cored bar member via a coupling pin, wherein the steering wheel employs a configuration in which the coupling pin extends from the airbag module side to the cored bar member side. The steering wheel according to the present invention includes: a coil spring arranged outside the coupling pin; and a support member supporting the upper end of the coil spring at a peripheral part of the coupling pin. Moreover, the support member includes a hook which includes: a support surface protruding in the direction vertical to the shaft of the coupling pin in order to support the upper end part of the coil spring; and a side extending from this support surface towards the lower side of the coupling pin. In addition, the coil spring is configured so as not to interfere with the side of the hook.

Abstract: An airbag apparatus equipped in a vehicle seat having a seat cushion that forms a seating surface and a seat back that forms a backrest includes: an inflator that generates inflation gas; and an airbag housed within at least the seat back and deployed by inflation gas released from the inflator. The airbag includes a pair of left and right side chambers that deploy towards the front from a side portion of the seat back and an upper chamber that deploys above the head of a passenger. The airbag is rolled in a direction that intersects the longitudinal direction from a flat unfolded state prior to being housed or folded to be compressed into a long bar shape. A folded portion is formed by folding at least a location corresponding to the upper chamber of the long bar shaped airbag to house the folded portion above the seat back.

Abstract: [Object]. An object is to suitably control the deployment shape of an airbag, thereby improving the occupant restraining performance. Another object is to reduce damage to an occupant located close to a steering wheel or an instrument panel.
[Solving Means]. An airbag device according to the present invention includes: a gas generator that generates expansion gas; an airbag that expands and deploys due to the expansion gas to restrain an occupant; and a diffuser disposed inside the airbag to control a flow of the expansion gas. Given that a direction toward the occupant is a first direction, the diffuser includes a receiving surface disposed between the gas generator and the airbag in the first direction to receive the expansion gas discharged from the gas generator; and a plurality of band-like connecting members having one end connected to an edge of the receiving surface and the other end directly or indirectly connected to the gas generator.

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.
