Abstract

An airbag module (10) with a housing (11) accommodating a gas generator (12) and a folded airbag (13) whose deployment opening (14) is closed before activation of the airbag (10) by a cover (15) fixed on the housing (11) by at least one predetermined breaking point (18) and to secure the opened cover (15) on the housing (11). An arrester strap (20) is positioned in a displaceable manner between the cover (15) and the housing (11). The cover (15) bearing a manufacturer emblem (17) on its exterior is secured on the housing (11) by means of a hinge (19) and the arrester strap (20) is attached by its one end (22) to a part affixed to the housing and encloses at least an area of the cover (15) or the manufacturer emblem (17) in a loop (27).

Claims

1. An airbag module comprising a housing accommodating a gas generator and a folded airbag whose deployment opening is closed before activation of the airbag by a cover fixed on the housing by at least one predetermined breaking point, and to secure the cover on the housing after the cover has opened an arrester strap is positioned in a displaceable manner between the cover and the housing, the arrester strap is formed of a length of strap material folded in a double layer arrangement to form two plies, each of which has a ply end, the arrester strap is attached by the two ply ends to an exterior side of the housing and is guided through a housing opening, wherein on the inside of the housing the two plies of the arrester strap form the loop enclosing the area of the cover, the cover bearing an emblem on its exterior and the cover is secured on the housing by a hinge and the arrester strap is attached by an end to a part affixed to the housing and the loop of the arrester strap wraps around at least an area of the cover.

2. The airbag module according to claim 1, wherein the arrester strap is fully displaceable within the interior of the housing and is secured by the one end to an interior part affixed to the housing.

3. The airbag module according to claim 1, wherein the arrester strap is attached by the two ply ends to an exterior side of the housing and is guided through a housing opening into the interior of the housing.

4. The airbag module according to claim 1, wherein the two ply ends of the arrester strap are attached to a stud bolt of the gas generator protruding from the housing.

5. The airbag module according to claim 1, wherein a securing pin is positioned on the exterior side of the housing to which both ply ends of the arrester strap are attached.

6. The airbag module according to claim 1, wherein the emblem is affixed to the cover.

7.
