  • Air-bag arrangement and a method of inflating an air-bag
    Patent number: 7025375
    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).
