Abstract
A method of folding a gas bag for a vehicle occupant restraint system comprises the following steps: unfolding the gas bag between a base and a hold-down, a traction envelope extending around the gas bag and being passed through the hold-down at a first end, a first lead-through of the traction envelope through the hold-down being contoured so as to correspond to that required of the gas bag when folded; pulling out the traction envelope by means of the first end from a space between the base and the hold-down such that the gas bag is pushed together inside the traction envelope. There is further proposed a gas bag folded by such method.
