Abstract: An airbag for protecting a vehicle occupant comprising a first and a second material layer each having edge regions, wherein the first and the second layers are sewn together along the edge regions. A fastening section adapted for attaching to a part of the vehicle and connecting to a gas generator configured to inflate the airbag with a gas in response to an accident. A first and a second chamber region disposed opposite a dividing seam, wherein each of the material layers includes a first and a second material section each matched to one of the first or second chamber regions.

Abstract: An air-bag unit for a vehicle seat including a squab (2) and a back-rest (5). The back-rest (5) includes a frame which is covered with upholstery (7). An air-bag unit (22) has an inflatable air-bag (28) connected to an inflator (23) to inflate the air-bag 28. The air-bag unit 22 is mounted to the back-rest frame (6) so as to be located inboard of part of the frame (10) with the inflator (23) being located adjacent the rearmost region of the frame (6) and positioned to direct gas into the air-bag (28) in a generally forward direction. The arrangement is such that actuation of the air-bag unit (22) will cause the air-bag (28) to inflate so that at least part of the air-bag (28) lies between the frame (6) and the occupant (16) of the seat.

Abstract: A side air bag is disclosed for a motor vehicle, and takes the form of a three-dimensional airbag which is formed from two super-imposed layers of fabric. The super-imposed layers of fabric, when laid flat, have a substantial common area of super-imposition. Infill pieces formed from either at least one gusset forming insert or from a portion or portions of fabric of one or both of the fabric layers which extend beyond the area of super-imposition are provided. The air-bag has an inflatable region towards the upper part of the air-bag and an inflatable region towards the lower part of the air-bag. The two inflatable regions are separated by a part of the air-bag which is constrained when the air-bag is inflated, to have a thickness less than the thickness of either of the said regions.

Abstract: An air-bag (1) having an inflatable region forming two chambers (3,4) divided by a seam (5). The seam extends towards a back part (6) of the air-bag. A gas generator unit (14,15) is located between the end of the seam (5) and the back part (6) of the air-bag. A strap (21) passes through an aperture (8) formed in a terminal part of the seam (5) to draw the terminal part of the seam to the gas generator unit (14,15) thus effectively sealing the two chambers (3,4). The chambers (3,4) may be inflated to different pressures.
