Abstract

The invention relates to a method of folding an airbag (10), especially an airbag (10) to be arranged beneath a vehicle roof (50), comprising an injection orifice (11), a guiding portion (13) arranged adjacent thereto in the longitudinal direction and an inflating portion (12) arranged adjacent to the guiding portion (13) in the longitudinal direction, the method including flatly spreading the airbag (10); laterally folding, especially zigzag folding, at least in portions at least one side part (30; 30′) of the airbag (10) in the direction of the longitudinal axis (L) of the airbag (10); furling the inflating portion (12) at least in portions starting from a trailing edge (26) of the airbag (10) that is maximally spaced from the injection orifice (11) in a first furling direction (AR) in the direction to the injection orifice (11); and forming the guiding portion (13) by laying at least one folding including a first folding bend (14) against the first furling direction (AR) so that the deployment behavior of the airbag (10) is influenced.
