  • Patent number: 11351950
    Abstract: A vehicle seat for supporting an occupant in a sitting position includes a backrest, and an airbag unit. The airbag unit comprises an inflatable airbag provided in an initially rolled and/or folded airbag package, and an inflator actuable to direct inflating gas into the airbag to inflate the airbag into an inflated configuration. The airbag comprises a pair of inflatable chambers which are physically connected to one another via a connecting interface, and are fluidly isolated from one another.

  • Patent number: 11338757
    Abstract: There is proposed a vehicle seat configured to support an occupant (401) in a sitting position, the seat comprising: a squab (27), a backrest (28), and an airbag unit. The airbag unit comprises an inflatable bag (1) and an inflator (34). The airbag comprises an inflatable chamber (8, 9; 208). The airbag further comprises an inflatable guide (2), connected to the inflator and the inflatable chamber. Upon actuation of said inflator, said inflatable guide is at least partially inflated before the inflatable chamber, thereby initially urging the inflatable chamber away from the backrest of the seat. The airbag is configured such that after the inflatable guide is at least partially inflated, the inflatable chamber inflates into a deployed position in which it defines an inflated shroud which extends over said sitting position and provides lateral protection to said occupant of the seat in said sitting position.

  • Patent number: 10967826
    Abstract: An air bag device for a vehicle seat has a first air bag portion to be attached to at or close to a first lateral side of a backrest and a second air bag portion to be attached to a second lateral side of a backrest. The first air bag portion and second air bag portion are connected with each other by a third air bag portion designed to be located along a part of the upper portion of a backrest. The air bag device is designed to, when mounted to a vehicle seat, limit the lateral movement of the torso of an occupant and protect an occupant. The third portion will contribute with an increased stability of the air bag device when deployed. The air bag device may be adapted to protect the head of an occupant from injuries.

  • Patent number: 8702123
    Abstract: A vehicle seat includes a seat frame, a first air-bag unit and a second air-bag unit. The seat frame is at least partially covered by a padding material and substantially covered by a cover. The first air-bag unit includes a first air-bag mounted within an outboard side of the seat, and substantially covered by the cover. The second air-bag unit includes a second air-bag mounted within the outboard side of the seat and substantially covered by the cover. The first air-bag is configured to inflate and burst through the cover, when activated, and to bear against an occupant of the seat sitting in a normal position in the seat, thereby exerting a pushing force against the occupant in an inboard direction. The second air-bag is configured to inflate and burst through the cover when activated, and to occupy a position between an occupant of the seat and an exterior side wall of the vehicle.

  • Publication number: 20120267880
    Abstract: An airbag for a motor vehicle includes an airbag skin having two side walls which enclose a gas chamber. The airbag skin is at least partially rolled to a shaped package in the resting state of the curtain airbag, with the shaped package having a non-circular cross-section. In order to provide a cost-effective way to produce such an airbag and to ensure that the airbag shows a deployment behaviour of a rolled package, the non-circular cross-section is permanent as long as the pressure inside the gas chamber does not exceed the pressure of the environment and is obtainable by plastic conversion of a rolled package with a circular cross-section.

  • Patent number: 8220831
    Abstract: In at least one embodiment of the present invention, an inflatable curtain for a motor vehicle is provided. The inflatable curtain is formed of layers of fabric and is deployable from a rolled state forming a roll to an inflated state. The air-bag comprises part of the air-bag that forms the upper-most edge of the air-bag when the air-bag is in the inflated state extending downwardly from the roll to lie proximate a side part of the motor vehicle on which the air-bag is to be mounted. At least a portion of the roll is positioned above the upper-most edge in the rolled state and is driven downward below the upper-most edge during deployment to the inflated state. The air-bag further provides a gas flow duct. When the air-bag is in the rolled state, the gas flow duct is provided at the top part of the roll.
