Abstract: An airbag is formed in a bag shape by joining margins of one pair of main body cloth portions. Inflation gas is supplied from an inflator to the airbag according to an impact given from the side of a vehicle seat. With this supply, the airbag deploys and inflates. A longitudinal partition portion is laid between the one pair of main body cloth portions. The longitudinal partition portion partitions an interior of the airbag into a front part and a rear part and has a communication hole. An inside one of the main body cloth portions constituting the airbag is attached to a car. The airbag is attached to a side frame inside the vehicle seat at a position between a rear end of the inside main body cloth portion and the longitudinal partition portion.

Abstract: An airbag of a head-protecting airbag device includes a bag body and a connecting member. The bag body includes a general inflatable portion and a terminal inflatable portion adjoining the general inflatable portion and located at a terminal region in a front and rear direction of the bag body. The connecting member is disposed over an outboard side of the terminal inflatable portion and includes at the leading end a mounting portion to be secured to a periphery of a vehicle window. The root end of the connecting member is jointed to a closed portion of the bag body at least by two jointing points disposed away from each other in an up and down direction. The jointing points are generally equally distant from the mounting portion.

Abstract: An airbag of a head-protecting airbag device includes a bag body, a plurality of mounting tabs for mounting an upper edge of the bag body on the vehicle body, and a tension cloth. The bag body includes at its terminal region in a front and rear direction where the tension cloth is located a terminal inflatable portion that is partitioned from a remaining general inflatable portion by a terminal partitioning portion. The terminal inflatable portion is so deployable that its upper end region be deployed on an inboard side of a pillar. The mounting tabs include a terminal mounting tab located at the terminal region where the terminal inflatable portion is located and a general mounting tab located at the general inflatable portion. An upward protruding amount of the terminal mounting tab out of the bag body in an unfolded state is greater than that of the general mounting tab.

Abstract: A side airbag apparatus includes an airbag main body. The inside of the airbag main body is divided by a vertical partition including a gas flow restrictor at least into an upstream inflation portion, which is located rearward of the vertical partition and receives inflating gas, and a downstream inflation portion, which is located forward of the vertical partition and receives the inflating gas that has passed through the upstream inflation portion and the gas flow restrictor. The dimension of the vertical partition in the widthwise direction of the automobile seat is set to a dimension that is equal or approximate to the dimension of the airbag main body in the widthwise direction in a case in which the airbag main body is inflated without the vertical partition.

Abstract: An airbag main body is divided into a first inflation chamber, a second inflation chamber, and a third inflation chamber. The third inflation chamber is inflated beside the lumbar region of an occupant. The vertical partition has a communication hole that connects the first inflation chamber and the second inflation chamber to each other. The airbag main body has a gas passage, which extends in the up-down direction and surrounds at least the gas outlet of an inflator. The gas passage bridges the first inflation chamber and the third inflation chamber. The gas passage has an upper opening, which faces a part of the first inflation chamber that is inflated beside the shoulder region of the occupant. The gas passage also has a lower opening, which faces the third inflation chamber.

Abstract: A lateral partition is formed by a pair of structural fabric portions, each of which has a first peripheral portion and a second peripheral portion. The first peripheral portions of the structural fabric portions are each joined to one of main body fabric portions. The second peripheral portions of the structural fabric portions are joined to each other by a joint portion provided along the second peripheral portions. An inner tube extends over the upper inflation chamber and the lower inflation chamber, while intersecting with the lateral partition. A rear peripheral portion of a part of the inner tube is joined to the main body fabric portions by a part of the peripheral joint portion, and a front peripheral portion of the part is joined to the structural fabric portions by the joint portion.
