Abstract
An airbag, a process for folding same and an apparatus for carrying out the folding process are disclosed. In order to produce a folded airbag as well as a process and apparatus for manufacturing same which ensure that the airbag can unfold very quickly without obstruction evenly where possible in all directions when the associated gas generator is activated, the airbag has main fold lines which run at least in part along closed tracks around an imaginary center on the substantially empty spread-out airbag. The corresponding process ensures such a path of the main fold lines and the apparatus has folding elements which are movable relative to each other and which have projections directed towards each other in the direction of movement wherein each projection or group of projections defines a closed track running round a center wherein tracks extending from inside to outside are provided at increasing distance from the center.
