Abstract:
1. An airbag for a vehicle occupant restraint system comprising: a first chamber and a second chamber, which can he inflated for protection of a vehicle occupant; and an outflow element with an outflow duct via which gas can flow out of the first chamber, when internal pressure in the first chamber exceeds internal pressure in the second chamber, wherein the outflow duct can be compressed by action of the internal pressure in the second chamber such that an outflow of gas out of the second chamber is counteracted, when the internal pressure in the first chamber is lower than the internal pressure in the second chamber, wherein the outflow element has a two-layer material piece, wherein the two-layer material piece has a folding edge, wherein the outflow duct is formed by folding in a section of the two-layer material piece in a region adjacent an edge of the two-layer material piece, wherein the edge is located at an end of the folding edge, such that the outflow duct comprises a first outflow opening and a second outflow opening, wherein the first outflow opening is located in a plane which is oriented diagonal to an axis of the outflow duct and the second outflow opening is located in a plane which is oriented crosswise to the axis of the outflow duct.
