Abstract: An airbag is inflatable in such a manner as to separate a vehicle-side wall which is deployable towards a vehicle body structure and an occupant-side wall which is deployable towards an occupant for catching the occupant. The airbag is configured to be supported by the vehicle body structure on the vehicle-side wall when catching the occupant with the occupant-side wall. The airbag includes a recessed section on left and right sides of and in a vicinity of the center of the occupant-side wall and a tether that connects the bottom of the recessed section to the vehicle-side wall in order to form the recessed section. Opposing walls of the recessed section press each other in a separable fashion when the airbag is inflated. The tether allows gas communication between a central region of the airbag and a peripheral region of the airbag which surrounds the central region, inside the airbag.

Abstract: A lateral partition of a side airbag apparatus extends in a front-rear direction to divide the interior of an airbag into an upper inflation chamber and a lower inflation chamber. A vertical partition extends vertically and includes a communication portion. The vertical partition divides the upper inflation chamber into an upper-rear inflation chamber, to which inflation gas from a gas generator is supplied, and an upper-front inflation chamber, to which the inflation gas is supplied via the communication portion. An inner tube regulates the flow of the inflation gas to direct to the upper-rear inflation chamber and the lower inflation chamber. The rear ends of two first fabric portions of the vertical partition are joined to the upper parts of the front ends of two second fabric portions of the inner tube by a first vertical joint portion.

Abstract: An airbag of a side airbag apparatus includes an upstream inflation portion, which inflates by inflation gas, and deploys frontward at a side of a vehicle seat. An opening is provided at a wall portion of the upstream inflation portion. A pressure regulator valve closes before an occupant is restrained by the upstream inflation portion, thereby restricting the inflation gas in the upstream inflation portion from flowing through the opening. Upon the occupant restraint, the pressure regulator valve cancels the restriction in response to a change in a tensed state of the dividing portion by an external force applied due to the restraint. A tear seam that connects valve body portions of the pressure regulator valve delays the opening time of the pressure regulator valve upon the occupant restraint by the upstream inflation portion relative to the opening time set only by the pressure regulator valve.

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: 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: An airbag is stored in a storage portion provided in a side of the seat back of a car seat and fixed to a side frame portion. The airbag is deployed and inflated by inflation gas that is supplied in response to an impact from a side of the seat back. The airbag displaces a cover main body of a cover sideways from the seat back with a hinge portion function as a pivot, so that the storage portion is opened. The airbag includes an upstream inflation portion, which forms a rear part and receives inflation gas, and a downstream inflation portion, which is located forward of the upstream inflation portion. The downstream inflation portion receives inflation gas via the upstream inflation portion. The upstream inflation portion has a front end that is located forward of a front end of the cover when the upstream inflation portion is inflated.

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 inflation portion of an airbag main body is divided into a first inflation chamber, a second inflation chamber in front of and adjacent to the first inflation chamber with a vertical partition in between, and a third inflation chamber below the first inflation chamber with a lateral partition in between. The vertical partition has a pressure regulator valve. Before the first inflation chamber restrains an occupant, the pressure regulator valve restricts flow of inflation gas from the first inflation chamber to the second inflation chamber. When the first inflation chamber restrains the occupant, the pressure regulator valve opens in response to a change in the tensed state of the vertical partition due to the applied external force generated by the restraint, thereby cancelling the restraint. The lateral partition has a check valve, which restricts flow of inflation gas from the third inflation chamber to the first inflation chamber.
