Abstract: An airbag device includes a seat frame that forms a skeleton of a vehicle seat on which an occupant of a vehicle sits; an airbag that is disposed on a backrest portion that supports a back of the occupant in the vehicle seat and that is deployed by supply of gas; and a gas generator that is disposed at a seating surface portion that supports buttocks of the occupant in the vehicle seat and that generates gas to be supplied to the airbag; where a part that is a portion of the seat frame and includes at least a portion of a back frame forming a skeleton of the backrest portion, is formed as a flow tube that connects to the airbag to supply gas generated by the gas generator to the airbag.

Abstract: The airbag device protects the occupant seated in the vehicle seat disposed in the vehicle. An airbag device includes a first airbag group and a second airbag group that are disposed in the vehicle seat in correspondence with impacts from two different directions and that respectively include a plurality of airbags; a gas generation unit that is disposed in a seat cushion, of the vehicle seat, that supports the buttocks region of the occupant and that generates gas to be supplied to the first airbag group or the second airbag group; and a switching unit that switches the supply of gas to either the first airbag group or the second airbag group.

Abstract: A coupling structure includes a first coupling portion formed by one end portion of a first tube, and a second coupling portion formed by one end portion of a second tube, and is configured such that the first coupling portion is inserted in the second coupling portion, the first coupling portion and the second coupling portion are coupled, with the second tube being pivotable with respect to the first tube, and a gap is formed between an outer surface of the first coupling portion and an inner surface of the second coupling portion in a first state in which a fluid is not flowing through the flow path, and in a second state in which the fluid is flowing through the flow path, pressure of the fluid causes the first coupling portion to deform to expand toward an outer side of the flow path to reduce the gap.

Abstract: An airbag device (1), having an airbag (10), is installed in a side wall (91) inside a vehicle cabin. The airbag (10) includes an inflatable section (30) configured to be inflated with gas and is disposed in an upper portion of the side wall (91). An inflator (2) supplies gas to the inflatable section (30), inflating and deploying the airbag (10) downward. A connecting member (50) connects the airbag (10) and the vehicle body (99) and is pulled between the vehicle body (99) and the airbag (10) that is being inflated and deployed. When the airbag (10) is inflated and deployed, a support portion (51) of the connecting member (50) supports the inflatable section (30) from the side wall (91) side of the airbag and pushes it toward the inner side of the vehicle cabin.

Abstract: An action of once strongly pressing an airbag against a pillar trim at the initial stage of deployment is omitted to enable the airbag to be quickly inflated and deployed without reducing the deployment speed thereof. An airbag device includes a folded airbag (10) that is attached to an upper part of a side wall inside a vehicle cabin in the front-rear direction of a vehicle, and an inflator that inflates and deploys the airbag (10) to the lower side of the vehicle. The airbag (10) includes a roll-folded portion (10R) rolled from one end thereof opposite from an attaching side, and an accordion-folded portion (10J) continuous with the roll-folded portion (10R) and folded in an accordion manner. The accordion-folded portion (10J) is folded so as to be located at a side of the roll-folded portion (10R).

Abstract: In an airbag device to be mounted to a vehicle-body side wall, an airbag and a mounting bracket are temporarily, but securely, attached to each other, so that mounting of the airbag to the vehicle-body side wall can be easily performed. A bolt (50) is inserted through a plurality of mounting tabs (11) provided on an airbag (10) of an airbag device (1), a mounting bracket (40) having inner and outer plates (41) and (42), and an annular member (44) provided in the inner plate (41). In this state, a toothed washer (70) is fitted and temporarily attached to the bolt (50). The annular member (44) is fastened by screwing the bolt (50) into a nut (55) attached to the vehicle-body side wall (15) when the airbag (10) is mounted to a vehicle-body side wall (15).

Abstract: A curtain airbag device for a vehicle has a curtain airbag main body 17 that is disposed along a longitudinal direction of a vehicle body while covered with an A pillar trim 41 and roof trim 42, and folded in an A pillar 7 and a roof side rail part 30 of the vehicle body so as to be able to deploy downward within a cabin. The curtain airbag main body 17 is provided with a twisted part 17b that is twisted such that an initial deployment force, generated upon inflation and deployment of the curtain airbag main body 17 located in a vicinity of the A pillar trim 41, is acted in a separation direction in which the A pillar trim 41 is parted away from the A pillar part 7, to push open the A pillar trim 41 toward an inside of the cabin. At least an upper surface of the twisted part 17b is regulated by a supporting bracket 21 and disposed in the vehicle body.

Abstract: An airbag is quickly inflated and deployed along an inner side wall of a vehicle while suppressing variations of the deployment direction of the airbag inflated and deployed from an upper part of the vehicle. An upper edge side of an airbag (2), which deploys first, is bellows-folded to form a bellows portion (2J), and a lower edge side continuous with the bellows portion (2J) is roll-folded toward the vehicle's exterior side (G) to form a roll-folded portion (2R). The roll-folded portion (2R) is formed to have a larger width than the bellows portion (2J) in the vehicle's width direction and the both sides thereof are folded back upward. The bellows portion (2J) is folded in substantially half and is wrapped by the roll-folded portion (2R) from below and is accommodated therein.

Abstract: A development restricting member is configured to include a fixing section attachable to a body of a vehicle above the pillar garnish, a holding section opposing to the fixing section, and a middle connecting section connecting a lower end part of the fixing section and a lower end part of the holding section, wherein an upstanding section is provided in a middle part of a base end part and a top end part of the holding section to extend toward the fixing section, so that a folded curtain airbag is housed so as to be surrounded by the fixing section, the holding section, and the upstanding section.

Abstract: An airbag (10) has a vent hole (18) in one side end portion. One end of a third base fabric (20) is sewn to the airbag (10) through a first sewn portion (23) that closes the vent hole (18), and the other end of the third base fabric 20 is sewn to the other side end portion of the airbag (10) through a second sewn portion (24). The first sewn portion (23) has weaker binding force by sewing than the second sewn portion (24) so that the first sewn portion (23) is separated to open the vent hole (18) when tension force is applied from the third base fabric (20) to the first and second sewn portions (23) and (24).
