摘要：
A method for producing a valve device is provided. The airbag has at least one substantially air-permeable textile, fabric layer and with a film. The textile layer and the film are arranged in a deep-drawing tool with at least area-wise reciprocal overlapping. The film is deep-drawn in deep-drawing regions by the deep-drawing tool to form a plurality of depressions of the film. The textile layer is connected to the film in regions of the film differing from the deep-drawing regions by the deep-drawing tool.
