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.

Vehicle airbag system

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. The airbag unit is mounted and configured such that, upon actuation of said inflator to inflate the airbag, the inflatable chambers inflate into respective deployed positions in which they: i) extend forwardly from respective opposing and laterally spaced-apart side regions of said backrest; and ii) extend upwardly, and laterally inwardly across an uppermost region of the seat towards said connecting interface, so as to thereby cooperate to define an inflated shroud around at least an uppermost region of the backrest so as to extend over the sitting position and provide lateral protection to a said occupant of the seat in the sitting position.

Vehicle seat

There is proposed a vehicle seat configured to support an occupant () in a sitting position, the seat comprising: a squab (), a backrest (), and an airbag unit. The airbag unit comprises an inflatable bag () and an inflator (). The airbag comprises an inflatable chamber (). The airbag further comprises an inflatable guide (), 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.

Airbag unit for a vehicle seat

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.

Air bag device and vehicle seat provided with an air bag device

An attachment bracket for fastening an airbag to a vehicle structure includes an opening into which a strap connected to the airbag can be inserted, and a clamping surface provided for resting against the vehicle structure. The attachment bracket is formed from at least a first layer forming the clamping surface and a second layer spaced from the first layer in a spring elastic manner. The first and the second layers can be located on the same side of the vehicle structure. The attachment bracket can be fastened to the vehicle structure by a fastening means. The distance between the first and the second layer can be reduced by fastening the attachment bracket with the fastening means. A clamping force acting between the first layer and the vehicle structure can be generated by reducing the distance.

Attachment bracket and fastening device for fastening an airbag to a vehicle structure

An airbag arrangement with an inflatable curtain airbag for a vehicle includes fixation elements to fix the inflatable curtain airbag to the interior side structure of the vehicle. The airbag further includes an inflatable area to cover parts of the interior side structure of the vehicle. A fender airbag is provided adjacent to the inflatable area and/or the fixation elements of the inflatable curtain airbag. The fender airbag is inflated with a time delay with respect to the inflation of the inflatable area of the inflatable curtain airbag.

Airbag arrangement

A fixing clamp for fixing an airbag on a gas generator includes a first support portion adapted to the outer shape of the gas generator and a second wrapping portion extending from the support portion. The wrapping portion with its free end can be connected to the support portion. The wrapping portion is designed to be extensible.

Fixing clamp and airbag unit

A curtain airbag for installation in the roof frame area of a motor vehicle exhibits at least one guide chamber which is located in the upper section of curtain airbag and which is connected with its inflatable area from the point of view of gas flow. The at least one guide chamber can be inflated on the outer side of the curtain airbag when this is in a mounted state. The upper section of curtain airbag is directed downwards when in the mounted state.

Curtain airbag and vehicle

An airbag having an airbag fabric skin () enclosing an interior gas space with a first edge () extending from a first end () to a second end (), whereby an accommodation area (A) for a gas generator () is located at the first edge outside the gas spaced extending parallel the first edge (), which exhibits an area () of a deflector element) which accommodates the gas generator. In order to ensure that the airbag unit consisting of gas generator and airbag halves in a thrust-neutral manner in case of a fire, deflector element () consists of a tubular, flexible element, whereby the deflector element () exhibits an upper and lower area () whose lower area () is located inside the gas space (G). The deflector element is connected with the airbag skin in an intermediate area () which is located between upper and lower areas.
