Abstract: A gas bag (1) for use in a vehicle occupant restraint device comprises a wall part (3) of an uncoated fabric and a heat protection device (11) applied onto a section of the wall part (3). The heat protection device (11) is formed from at least one layer of a further uncoated fabric (13) glued to the wall part (3) using a flame-retardant adhesive (15).

Abstract: A device for folding a gas bag (10) comprises a positioning means for the gas bag (10) with a tubular folding device (32). The positioning means positions the gas bag (10) such that upon an axial movement of the tubular folding device (32), the gas bag (10) is turned over the tubular folding device (32). A method of folding a gas bag (10) having an inflation opening, using a device of this type comprises the following steps: positioning the tubular folding device (32) on the side of the gas bag (10) opposite the inflation opening; axially displacing the tubular folding device (32) through the inflation opening, so that the gas bag (10) is turned over the tubular folding device (32); and withdrawing the tubular folding device (32) from the inflation opening.
