Vehicle occupant restraining system comprising a central airbag

A vehicle occupant restraint system comprising a center airbag which, in an inflated state, extends between two vehicle seats positioned next to each other and which includes an inflatable torso gas bag and an inflatable head gas bag connected to the torso gas bag, wherein the torso gas bag has a laterally projecting, as seen in the longitudinal direction of the vehicle (L), inflatable protrusion which is designed and arranged to abut, in the completely inflated state of the center airbag, against a vehicle structure between the vehicle seats and to support the center airbag against a lateral force (F), wherein a cut of the torso gas bag includes first and second portions which, relating to the inflated center airbag, are connected to each other along mirror-inverted outer contours, and wherein the second portion has a folding area which forms the inflatable protrusion in the inflated center airbag, wherein the folding area comprises an outer edge portion which is connected only to itself in superimposed sections of the folding area, and wherein the folding area comprises a first folding line which extends from a terminal point at the circumferential contour of the torso gas bag opposite to the contact surface to a first end of the outer edge portion of the folding area, and a second folding line which extends from the terminal point to a center (P) of the outer edge portion and divides the outer edge portion into two mirror-symmetrical sub-portions.
