An airbag unit for a motor vehicle safety device includes an inflatable airbag and a cover. The inflatable airbag is formed of flexible material and provided in a rolled and/or folded package. The cover extends around at least part of the package. The cover includes a first cover portion and a second cover portion. The first cover portion is located on a first side of the package, and at least a region of the second cover portion being located on an opposite second side of the package. The second cover portion is substantially flexible and is connected to or formed integrally with the first cover portion, and the first cover portion has a predetermined stable shape and is relatively rigid in comparison to the second cover portion.

A method of rolling or folding an airbag to a thin tight tube, includes stretching the airbag during the rolling or folding in length direction.

Packaging method for an airbag, airbag and a device for folding or rolling an airbag

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 fibers, at least some of the fibers 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 fibers; simultaneously heating and pressing the intermediate package to form a compressed package in which at least some of the fibers are fused to one another, the compressed package having a stable shape defined by the fused fibers.
