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: A vehicle seat and an airbag system, the seat having a backrest and a squab, extending from the backrest in a longitudinal direction, the backrest extending in height from the squab at a first lower position to a second upper position arranged proximal to shoulders of an occupant in a seated position, the airbag system having an airbag to receive inflating gas from an inflator to inflate the airbag, in which the airbag includes an upper region that extends over a head of the occupant in the seated position and a lower region that extends between a first and second side of the backrest and around a mid-section of the seated occupant, the airbag system having a tether system interconnecting the seat at the second upper position of the backrest and airbag to restrain the lower region of the airbag in the inflated configuration in the longitudinal direction.

Abstract: There is proposed a vehicle seat configured to support an occupant (42) in a sitting position, the seat comprising: a squab (27), a backrest (28), and an airbag unit. The airbag unit comprises an inflatable airbag (1) provided in an initially rolled and/or folded airbag package (33), and an inflator (34) actuable to direct inflating gas into the airbag (1) to inflate the airbag into an inflated configuration. The airbag (1) comprises a pair of inflatable chambers (8, 9) which are physically connected to one another via a connecting interface (17), and are fluidly isolated from one another. The airbag unit is mounted and configured such that, upon actuation of said inflator (34) to inflate the airbag (1), said inflatable chambers (8, 9) inflate into respective deployed positions in which they: i) extend forwardly from respective opposing and laterally spaced-apart side regions of said backrest (28); and ii) extend upwardly, and laterally inwardly across an uppermost region of the seat towards said connecting interface (17), so as to thereby cooperate to define an inflated shroud around at least an uppermost region of the backrest (28) so as to extend over said sitting position and provide lateral protection to a said occupant (42) of the seat in said sitting position.

Abstract: An airbag unit for a motor vehicle safety device includes an inflatable airbag and a cover. The inflatable airbag is formed of flexible material and provided in a rolled and/or folded package. The cover extends around at least part of the package. The cover includes a first cover portion and a second cover portion. The first cover portion is located on a first side of the package, and at least a region of the second cover portion being located on an opposite second side of the package. The second cover portion is substantially flexible and is connected to or formed integrally with the first cover portion, and the first cover portion has a predetermined stable shape and is relatively rigid in comparison to the second cover portion.
