A vehicle restraint system for a seated occupant including a lap belt system and an inflatable member mounted on the lap belt and restrained by the belt when inflated. The inflatable member is sized and shaped so that one inflatable member surface functions to prevent or limit inflatable member rotation by engaging a substantial area including the occupant's lap and seat thereunder. Another rearward member surface restrains occupant's torso movement. The belt may pass through or around the inflatable member. The lap belt system may contain the collision detector and gas creating arrangement.
