Abstract

A lateral impact gas bag for a vehicle occupant restraining system, comprising a wall 12 with an inlet opening 11 and a partition 15 in the interior of the gas bag to divide the internal space of the gas bag 10 into two adjacent chambers 30, 35, which may communicate with one another by a connecting opening 38 formed in the partition 15, is to be more rapidly positioned during a collision and shall more rapidly provide preliminary protection for an occupant of the vehicle. For this purpose the gas bag is so designed that the two chambers 30, 35 are elongated and the longitudinal extent thereof coincides with the preferred deployment direction, that the inlet opening 11 is provided at a first longitudinal end and the connecting opening 38 is provided at a second longitudinal end of the first chamber 30 and that the connecting opening 38 is shut off, in the folded condition of the wall 12, by overlying wall parts and during deployment of the wall 12 is only released on reaching a point adjacent to the second longitudinal end of the first chamber 30.
