    Abstract: An airbag device capable of restraining a motor vehicle occupant in a stable position even in an oblique collision. The airbag device includes a bag-shaped main bag inflated and deployed on a vehicle front side of the passenger seat, a bag-shaped center bag inflated and deployed on the inner side of the main bag in the vehicle widthwise direction, and a slit that provides a separation between the main bag and the center bag on the vehicle rear side. A rear end part of the center bag is inclined to gradually protrude rearward in the vehicle as the rear end part is extended upward and protrudes further to the vehicle rear side than at least the main bag.

    Abstract: An airbag device provided with an airbag and inflator integrally covering the head and side sections of an occupant seated in a vehicle seat. The airbag, includes, during expansion and deployment, a head protecting chamber that covers the head of the occupant and side protecting chambers that cover the side sections of the occupant, and is stowed in a rolled state, for example, from a first side of the backrest of the vehicle seat to the second side over the upper portion. An additional folding part is provided on the outer periphery of the airbag extending from the attachment end side to the backrest so as to cover at least a part of the outer periphery of the airbag on the side opposite to the seated occupant.

    Abstract: [Problem] To expand and deploy a hood-shaped airbag in a reliably sandwiched condition between the top of a shoulder of a seated occupant and a seatbelt in a normal set condition during a collision, and reduce injury to the occupant by a device other than an airbag such as a seatbelt or the like.
    [Resolution Means] An airbag device 11 contains an airbag 12 and inflator 13 integrally covering the head 2a and a side portion of a seated occupant 2. The airbag 12 in a flat condition prior to folding has a plurality of chambers 12c demarcated in a longitudinal direction. The chamber 12c has a head protecting chamber 12ca stored in an upper portion of a backrest portion 1b of a seat 1 and a pair of side protecting chambers 12cb stored in opposing positions separated in a vehicle width direction on both left and right sides of the backrest portion 1b. At the time of expansion and deployment, the side protecting chamber 12cb expands and deploys between the seatbelt 3 and occupant 2, and thus the airbag 12 is configured such that a space S is formed between the occupant 2 and airbag 12 deployed at a position where the seatbelt 3 passes.

    Abstract: When an occupant has moved from a normal seating position, a case can occur where a hood-type airbag cannot be expanded and deployed since the airbag is stopped in the process of expansion and deployment due to contact with the head of the occupant. An airbag device is provided having an airbag, and an inflator for supplying gas to the airbag. In an expanded and deployed state where expansion and deployment of the airbag has been finished, the airbag includes a head protection chamber for blanketing an occupant from a vertex part of the head to a temporal part of the head, and a pair of lateral part protection chambers that are arranged on both of the left/right sides of the head protection chamber and that blanket lateral sides of the occupant.

    Abstract: An airbag device for restraining an occupant even during an oblique collision and suppressing head injury values. An airbag device 100 includes: a passenger bag 112 which deploys on a front side of a passenger seat 104; a center bag 114 which deploys on an inner side in a vehicle width direction; a slit 128 which separates the passenger bag 112 and the center bag 114 from each other on a vehicle rearward side; and a tether belt 122 which which is connected to a first connecting part 124 on the center bag 114 and a second connecting part 126 on the passenger bag 112. The tether belt 122 is tensioned as the passenger bag 112 and the center bag 114 expand and deploy, and the center bag 114 restrains a side of the occupant head E1a while being supported by the tether belt 122.
