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 air-bag is formed using two substantially identical, but inverted, fabric elements. Each element defines a generally rectangular region having, at one narrow end thereof, a generally triangular extension, one side of which is co-extensive with one side of the rectangular region. The other side of the rectangular region has a triangular or thumb-like projection. The two elements are substantially superimposed with the rectangular regions thereof aligned. If the ends of the rectangular regions carrying the triangular extensions are separated, the projections or thumbs may be folded to form side-walls, and the triangular projections may be folded inwardly to form an end region. A single peripheral seam may seal the two elements together to form an air-bag.
