1. A valve mechanism for a gaseous medium of an airbag, the valve mechanism comprising:
- a first layer that includes at least one passage opening;
a second layer that includes at least one passage opening; and
an adjusting element in the form of a tube with an adjustable volume,wherein the at least one passage openings of the first and second layers are configured so as to be at least substantially closed in a closed position of the valve mechanism by a corresponding cover region of the other layer,wherein the tube adjusting element is configured so that expansion of the adjustable volume of the tube adjusting element pushes the tube adjusting element against and lifts at least one of the cover regions of the corresponding layer, at least in areas from the corresponding passage opening, in an at least temporary passage position of the valve mechanism, andwherein the first layer or the second layer is formed at least substantially from a fabric.

Abstract
A valve mechanism for a gaseous medium of an airbag is provided. The valve mechanism includes a first and second layer, which respectively include a passage opening that is substantially closed in a closed position of the valve mechanism by a corresponding cover region of the other respective layer. An adjusting element in the form of a tube with an adjustable volume provides a temporary passage position of the valve mechanism by lifting one of the cover regions of the corresponding layer from the corresponding passage opening.
