Abstract
Abstract The invention relates to a gas bag module comprising a gas bag, an outer contour of the gas bag being defined by a gas bag wall which has a front wall for the impact of an occupant with a centric opening as a transition to an indentation in the gas bag. The indentation is formed in that during inflation a center portion of the gas bag wall is prevented from freely moving and is restrained. A closure part is provided which encloses one of the indentation and the opening and engages the gas bag wall. A traction device is provided which is connected with the closure part. The traction device is attached such that due to a deployment of the gas bag a tensile force is exerted on the traction device and the tensile force is passed on to the closure part, and one of the indentation and the opening is at least partly closed.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
150 words
A gas bag module comprising: a gas bag, an outer contour of said gas bag being defined by a gas bag wall which has a front wall for the impact of an occupant with a centric opening as a transition to an indentation in said gas bag, said indentation being formed in that during inflation a center portion of said gas bag wall is prevented from freely moving and is restrained, a closure part which encloses one of said indentation and said opening and engages said gas bag wall, and a traction means being provided which is connected with said closure part, said traction means being attached such that due to a deployment of said gas bag a tensile force is exerted on said traction means and said tensile force is passed on to said closure part, and one of said indentation and said opening being at least partly closed.
Claim 2
Dependent Claim
150 words
A gas bag module comprising: a gas bag, an outer contour of said gas bag being defined by a gas bag wall which has a front wall for the impact of an occupant with a centric opening as a transition to an indentation in said gas bag, said indentation being formed in that during inflation a center portion of said gas bag wall is prevented from freely moving and is restrained, a closure part which encloses one of said indentation and said opening and engages said gas bag wall, and a traction means being provided which is connected with said closure part, said traction means being attached such that due to a deployment of said gas bag a tensile force is exerted on said traction means and said tensile force is passed on to said closure part, and one of said indentation and said opening being at least partly closed.
Claim 3
Dependent Claim
34 words
The gas bag module as claimed in claim 1 , wherein said traction means is on the one hand connected to said gas bag wall and on the other hand to said closure part.
Claim 4
Dependent Claim
44 words
The gas bag module as claimed in claim 1 , wherein in a completely inflated condition of said gas bag said traction means runs obliquely outwards to a lateral portion of said gas bag wall, said traction means being attached to said lateral portion.
Claim 5
Dependent Claim
23 words
The gas bag module as claimed in claim 1 , wherein said traction means is disposed in an interior of said gas bag.
Claim 6
Dependent Claim
30 words
The gas bag module as claimed in claim 1 , wherein said closure part is one of a strap and a rope surrounding one of said indentation and said opening.
Claim 7
Dependent Claim
37 words
The gas bag module as claimed in claim 1 , wherein said closure part is accommodated in a guideway provided in said gas bag wall so as to be movable with respect to said gas bag wall.
Claim 8
Dependent Claim
24 words
The gas bag module as claimed in claim 1 , wherein said closure part and said traction means are integrally connected with each other.
