Abstract
A method for folding an airbag for an airbag module is characterized in that an empty airbag is spread out and gathered in towards a center to give a folded airbag. The airbag is gathered inside a fixed vertical profiled section having a top and a bottom separated by a distance corresponding to the predetermined height of the folded airbag. Only a few gathering tools and only a few operations are necessary to gather the airbag. A device for carrying out the method is characterized by a lower part on which the airbag is spread out flat and an upper part separated from the lower part by a distance that corresponds to the vertical profile required for the gathered airbag. Gathering tools are mounted between the upper part and the lower part so that they surround the airbag and so that their position relative to the airbag can be changed.
