Abstract: An airbag apparatus includes a gas generator, and an airbag. The airbag includes a first fabric inner tube and a second fabric inner tube, both surrounding at least a gas injecting portion of the gas generator to have a double tubular shape. Common portions of the first inner tube and the second inner tube in a tubular circumferential direction are coupled to an airbag main body by a coupling portion extending in a tubular length direction, and other common portions which are separated from the common portions of the first inner tube and the second inner tube by a central angle (a central angle in a state where the airbag is only deployed and not inflated) of 70 to 180 degrees about the gas generator in the tubular circumferential direction are coupled to each other by a coupling portion extending in the tubular length direction.

Abstract: The outer shape of an airbag is formed by an airbag main body. The airbag has an insertion opening, which extends along the periphery of the airbag. The gas generator includes bolts. The lower part of the airbag main body is configured by a lower fabric portion, which has first insertion holes in the periphery. The bolts are inserted into the first insertion holes and fastened to the seat portion. A harness, which is connected to the gas generator, is drawn out of the airbag main body through the insertion opening. Among the first insertion holes, the one that is farthest from the harness is a first specified insertion hole. The lower fabric portion has a first slit, which extends from the inner periphery of the first specified insertion hole in a direction away from the adjacent general insertion hole.

Abstract: A seat cushion airbag device includes: an airbag disposed in a seat section of a vehicle seat; and a gas generator, the airbag including: an airbag main body; and an inner bag has gas release sections configured to release the inflation gas from the gas generator to the airbag main body in at least two positions, wherein: the inner bag and the airbag main body are inflated by the inflation gas to raise the seat surface of the seat section to regulate a restraint target object on the seat section from moving forward; and each of the gas release sections is constituted by a gas release hole, and of the gas release holes, an opening area of the gas release hole on the side closer to the blow-off opening section is set to be smaller than an opening area of the gas release hole on the remote side.

Abstract: A seat cushion airbag apparatus is applied to a vehicle seat including a seat unit having a seat cushion supported, from a lower side thereof, by a supporting portion of a seat frame, and an air blowing duct having a blow-out port below the seat cushion, wherein a conditioning air flowing through the air blowing duct is blown out upward from the blow-out port. An inflator is disposed at a location, which is spaced from the blow-out port in a front and rear direction of a vehicle, and an airbag is inflated between the supporting portion and the seat cushion by an inflation gas supplied from the inflator so that a seat face of the seat unit is raised to prevent a subject to be restrained on the seat unit from being moved forward.

Abstract: A seat cushion airbag device mountable to a vehicle seat, includes an airbag includes an inflation portion including an upper fabric portion and a lower fabric portion joined to form a bag shape. The inflation portion is inflated between a support portion and a seat cushion of the vehicle seat by an inflating fluid supplied in response to an impact applied to the vehicle from a front side, such that a seat surface of the seat portion bulges, thereby suppressing a forward movement of an object to be restrained on the seat portion. The airbag further includes a restriction member which extends in a front-rear direction of the vehicle seat within the inflation portion and which bridges the upper fabric portion and the lower fabric portion to restrict an inflated thickness of the inflation portion in the upper-lower direction.
