Abstract

A method and device for folding an airbag having a inner main fold and an outer main fold in a folded state. The airbag is fixed to a working surface, extended along a longitudinal axis away from the working surface, and fixed in the area of the inner or outer main fold. The airbag is then expanded, or contracted, to form the outer or inner main fold, respectively, and then compressed toward the working surface. A shaping body is preferably inserted into the airbag through an inflation opening to extend the airbag so that a folding element may activated to retain the airbag against the shaping body to form the inner or outer main fold.
