Zusammenfassung:An airbag unit for a motor vehicle safety device includes an inflatable airbag formed of flexible material and provided in a rolled and/or folded package. The package is held under compression by a cover which extends around at least part of the package. The cover is formed from a ductile fabric material including polymeric fibres, at least some of the fibres fused to one another to impart a predetermined stable shape to the unit. A method of packaging the airbag includes providing an inflatable airbag formed of flexible sheet material; rolling and/or folding the airbag and at least partially wrapping it with an initially flexible cover to form an intermediate package, the cover formed from a ductile fabric material including polymeric fibres; simultaneously heating and pressing the intermediate package to form a compressed package in which at least some of the fibres are fused to one another, the compressed package having a stable shape defined by the fused fibres.
