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 inflatable airbag is held under compression by a cover extending around at least part of the package. The cover is formed of a molded pulp material and is configured to impart a predetermined stable shape to the unit. A method of packaging an airbag in such a manner is also disclosed.

Airbag unit for a motor vehicle safety device and a related method of packaging an airbag

A knee airbag module for a motor vehicle. The airbag module has a housing which is preferably composed of plastic and has a housing base () and a wall extending from the housing base (), forming an outlet opening. A receptacle is provided in a first wall section. An airbag is folded into the housing, an air generator () which has outflow openings located within the airbag, and a covering element which closes the outlet opening. This covering element has a main section () which lies substantially in one plane, at least one first end section () accommodated in the at least one receptacle, and a second end section () situated opposite the first end section (), extends out of the plane of the main section () and is connected to the housing (). The covering element () is produced from a blank.

Airbag module and vehicle

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.
