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.

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.

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.
