摘要： An air-bag comprising: first and second sheets of fabric; an inlet into which gas will be introduced into the air-bag to inflate the air-bag when the air-bag is deployed; and a first seam which describes or forms part of a loop which encloses or substantially encloses an interior region, so that the interior region is separated from the inlet by at least the first seam, wherein at least one part of the first seam comprises one or more regions at which the first and second sheets of fabric are not joined to one another, to allow gas to flow into the interior region from a region outside the interior region, to allow inflation of the interior region during deployment of the air-bag.

摘要： There is provided a method of packaging an airbag for a motor vehicle safety device. The method comprises the steps of: providing an inflatable airbag formed of flexible sheet material; rolling and/or folding the airbag into an intermediate package having an initial cross-sectional thickness; simultaneously heating and pressing the intermediate package to form a compressed package having a reduced cross-sectional thickness relative to the intermediate package; subsequently placing the compressed package in a transportable cavity (14) having a shape and size comparable to the shape and size of the compressed package; and cooling the compressed package to ambient temperature whilst it is in said transportable cavity (14). Preferably, the transportable cavity (14) is provided within a transport unit having a plurality of said cavities (14) for the receipt of a plurality of airbags packaged in respective compressed packages. The or each airbag can be transported as a compressed package to a vehicle assembly plant, and allowed to cool to ambient temperature during transit.
