1. A gas bag module comprising:
- a gas bag including a gas bag wall which has a front and a rear wall section and including at least one chamber, an indentation running from said front wall section in an inflated state in a direction toward said rear wall section, which indentation is formed in that a part of said gas bag wall is prevented from an unimpeded movement towards outside of said module on unfolding of said gas bag, said gas bag, in a region of a mouth of said indentation, having a bulbous inflatable extension in flow connection with said at least one chamber of said gas bag, which extension closes said indentation, said indentation running obliquely from a lowest point thereof toward said front wall section.

Abstract
The invention relates to a gas bag module comprising a gas bag including a gas bag wall which has a front and a rear wall section and including at least one chamber. The gas bag further comprises an indentation running from the front wall section in an inflated state in a direction toward the rear wall section. The indentation is formed in that a part of the gas bag wall is prevented from an unimpeded movement towards outside of the module on unfolding of the gas bag. The gas bag, in a region of a mouth of the indentation, has a bubble-like inflatable extension in flow connection with the at least one chamber of the gas bag, which extension closes the indentation.

9. A gas bag module comprising:
-
a gas bag including a gas bag wall which has a front and a rear wall section and including at least one chamber, an indentation running from said front wall section in an inflated state in a direction toward said rear wall section, which indentation is formed in that a part of said gas bag wall is prevented from an unimpeded movement towards outside of said module on unfolding of said gas bag, said gas bag, in a region of a mouth of said indentation, having a bulbous inflatable extension in flow connection with said at least one chamber of said gas bag, which extension closes said indentation, said inflatable extension is constituted by two superimposed fabric pieces that are connected with each other at outer edges thereof, and said fabric pieces, for the purpose of forming passage openings to said chamber, being not connected with each other in at least one section of said outer edges. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)

17. A gas bag module comprising:
-
a gas bag including a gas bag wall which has a front and a rear wall section and including at least one chamber, an indentation running from said front wall section in an inflated state in a direction toward said rear wall section, which indentation is formed by a part of said gas bag wall prevented from unimpeded movement towards outside of said module on unfolding of said gas bag, said gas bag, in a region of a mouth of said indentation, having a non-symmetrical bulbous inflatable extension in flow connection with said at least one chamber of said gas bag, which extension closes said indentation, said gas bag wall being defined by fabric pieces, at least one of said fabric pieces resulting in a non-symmetrical gas bag shape in the inflated state to form said bulbous inflatable extension. - View Dependent Claims (18)

20. A gas bag module comprising:
-
a gas bag including a gas bag wall which has a front and a rear wall section and including at least one chamber, an indentation running from said front wall section in an inflated state in a direction toward said rear wall section, which indentation is formed in that a part of said gas bag wall is prevented from an unimpeded movement towards outside of said module on unfolding of said gas bag, said gas bag wall forming a bulbous extension defined by a separate gas bag wall portion and arranged within said indentation and closing said indentation, a gas bag wall portion defining said indentation circumscribing said separate gas bag wall portion defining said bulbous extension, and said extension being in flow connection with said at least one chamber of said gas bag. - View Dependent Claims (21, 22, 23, 24, 25, 26, 27)
