First Claim
1. A gas bag (10) for a vehicle occupant restraint system, including a limiting strap (12) which is guided along a wall (14) of said gas bag (10), said limiting strap (12) being shortened in an initial state by at least one gathered section such that said gas bag (10) is constricted and is not able to deploy freely, said at least one gathered section being extendable after a predetermined limiting strap tensile force is exceeded, so that said gas bag (10) may be deployed completely, said limiting strap (12) has a plurality of gathered sections being held in said gathered state by one releasable holding element (32) each, said holding elements (32) being configured such that they permit an extension of their associated gathered limiting strap sections offset in time at different limiting strap tensile forces.

7. A gas bag (10) for a vehicle occupant restraint system, including a limiting strap (12) which is guided along a wall (14) of said gas bag (10), said limiting strap (12) being shortened in an initial state by at least one gathered section such that said gas bag (10) is constricted and is not able to deploy freely, said at least one gathered section being extendable after a predetermined limiting strap tensile force is exceeded, so that said gas bag (10) may be deployed completely, wherein in an unfolded state said gas bag wall (14) comprises a front wall section (22) which faces a vehicle seat (19) when said gas bag (10) is installed, and a rear wall section (24) which faces away from the vehicle seat (19) when said gas bag (10) is installed, said limiting strap (12) extending from said rear wall section (24) across said front wall section (22) and back again up to said rear wall section (24).
