Abstract: An airbag device installed in a vehicle seat having a seat cushion forming a seat surface and a seatback forming a backrest, being provided with an inflator stowed in one side portion of the seatback that generates inflation gas, and an airbag stowed in the seatback in a rolled or folded state that deploys from one side portion by the inflator releasing the inflation gas. The airbag deploys toward the front of the seatback and includes an upper chamber region for protecting at least around the head and neck of the occupant and a lower chamber region for protecting mainly from the waist to the shoulders of the occupant.

Abstract: An airbag device installed in a vehicle seat having a seat cushion forming the seat surface and a seatback forming the backrest, and an inflator that generates expansion gas and an airbag that is deployed by the expansion gas released from said inflator. The airbag includes a pair of left and right side chambers that deploy forward from the side of the seatback and primarily protect the occupant's waist to shoulders, and an upper chamber that is continuous with the side chambers, deploys forward above the side chambers, and mainly protects the occupant's neck and head. On the left and right sides of the seatback, the location on the side where the seatbelt crosses near the shoulder is the first side, and the side opposite to said first side is the second side. A recess is formed on the first side of the airbag where the seatbelt fits.

Abstract: A curtain airbag device that allows easy recognition and correction of twisting of an airbag during attaching. The curtain airbag device can be stored in a compact manner during transportation. The curtain airbag device including an airbag that is disposed along a roof side rail of a vehicle interior, and that can deploy so as to cover a window portion on a side face of the vehicle interior, the curtain airbag device further including a cover that covers the airbag, at least, in a part of the folded or rolled airbag in the longitudinal direction. The cover is formed of a pliable fabric material of polymer fibers, and maintains the shape of the rolled-up airbag through mutual fusion of at least a part of the polymer fibers. A high stiffness portion harder than other portions and formed during the fusion of the cover is provided in the cover extending in the longitudinal direction of the cover.

Abstract: An airbag device configured such that, inflator gas is less likely to leak outside from an insertion hole formed on a cushion and into which the inflator is inserted during assembly of the airbag device. The airbag device 100 includes: a bag-shaped cushion 108 which deploys using gas supplied from inflator 110; an insertion hole 112 formed on the cushion and through which the inflator is inserted; and a covering part 120 provided on an inner side of the cushion and covers the insertion hole. The covering part includes: a first cloth piece 122 overlapping the insertion hole and on which a slit 126 that is elongated in one direction is formed; and a second cloth piece 124 positioned to overlap the first cloth piece and a slot 128 is formed having a longitudinal direction intersecting a longitudinal direction of the slit overlapping the insertion hole.
