Abstract: Described is a gas bag for a motor vehicle with a gas bag envelope surrounding a gas space, wherein the gas bag envelope comprises a front section (12) having an impact area (12a) and a rear section (14) directly connected with the front section (12) via a circumferential edge (11) having a support area (14a). Here, the rear section (14) has a folding for the contouring of the gas bag. In order to achieve that the gas bag adapts to a convexly bent surface shape of a part of the vehicle interior structure against which it rests without external catching bands or the like the folding consists of at least one first fold (18) extending parallel to the rear section and at least a second fold (20), wherein the second fold (20) is arranged in the first fold (18) and substantially stands perpendicularly to the rear section (14).
