Air-bag arrangement and a method of inflating an air-bag
First Claim
1. An air-bag arrangement for use in a motor vehicle to provide protection for an occupant of the motor vehicle, the air-bag arrangement incorporating an air-bag adapted, on inflation, to be located adjacent an occupant of a vehicle, the air-bag comprising at least three super-imposed layers including a first outer layer, an intermediate layer and a second outer layer, each layer being formed of fabric and connected to the or each adjacent layer to define a respective chamber set where the intermediate layer is attached to both the first and second layers at locations where the first and second layers are connected, at least one of the chamber sets incorporating a plurality of chambers, the chambers of one chamber set being off-set relative to the chamber or chambers of another chamber set so as to substantially overlap the chamber or chambers of another chamber set and means being provided to supply gas to the chamber sets wherein the air-bag is fabricated using a one-piece weaving technique, and wherein the air-bag has an extension, the extension constituting a gas supply duct adapted to supply gas to at least one of the chamber sets.

Abstract
An air-bag arrangement provides protection for the occupant of a motor vehicle. The air-bag arrangement incorporates an airbag (50) formed by two layers (51, 52) interconnected to form a first set of chambers (53, 54, 55, 56, 57, 58), having a plurality of elongated substantially parallel chambers. A further fabric layer (61) is connected to one of the two layers (52) forming the main part of the inflatable element to define a second chamber set including two chambers (62, 63). The chambers are off-set from the adjacent chambers (54, 55, 56) defined by the first two layers (51, 52). Apertures (59, 60) provided in the layer (52) allow for the inflation of the second set of chambers (62, 63).
