A way of folding an air bag used in an air bag module is disclosed, as well as a process and device for folding an air bag. The air bag is folded in the direction of an imaginary longitudinal axis, forming a ring with separate folds (10, 11) at its inner and outer sides, the imaginary longitudinal axis preferably extending thorugh the filling mouth (7) of the air bag. The folding process is characterised in that the empty air bas is stretched in the direction of an imaginary longitudinal axis and folded up in the direction of the longitudinal axis within a boundary, in particular a boundary having a ring-shaped cross-section. A device for folding the air bag has a moulded part (1), at least one device for introducing the air bag (6) into the moulded part and at least one device for compressing the air bag inside the moulded part. The advantage of the invention is that only a few process steps and a simple device are required for folding the air bag. |
