Abstract

The invention relates to a gas bag for an airbag module wherein the gas bag is folded in the rest position. According to the invention a telescopic folding is provided, as well as a method and a device for folding a gas bag, wherein chaotically folded sections extend around telescopic folds. The folding is conducted so that the gas bag is placed telescopically in folds into the inside of the gas bag step-wise, at least from one side, and is then compressed to form the chaotic folds.
