A vehicle occupant restraint system comprises an airbag module (12) including an inflator (18) and a frontally acting airbag (16), wherein the airbag (16) includes an inflator-side inflation end (46) as well as a first free end (56) located in the inflated state of the airbag (16) within a vehicle interior. In a first period during deployment of the airbag (16), the first free end (56) is still connected via a tether (74) to the airbag module (12), wherein the tether (74) becomes detached upon reaching a predetermined tensile force. When folding the airbag (16), the non-inflated airbag (16) is spread so that a second free end (58) is maximally distant from the inflation end (46) and a first outer wall portion is stretched in the longitudinal direction of the airbag (16), and the first free end (56) is located in the vicinity of the inflation end (46) and a second outer wall portion is stretched in the longitudinal direction of the airbag (16), wherein a third outer wall portion of the airbag (16) is folded back onto itself at least in a portion. The two lateral areas of the spread airbag (16) are folded toward the center, and subsequently the airbag (16) is rolled up from the second free end (58).
