Abstract: A 4-point occupant restraint belt system for a vehicle seat having a seat bottom and a back rest. A one-piece belt is connected to the vehicle at upper and lower attachment points disposed adjacent a first side of the vehicle seat, and a buckle is disposed adjacent an opposite second side of the vehicle seat. A latch is slidingly mounted on the belt and engagable with the buckle to secure the belt around a seat occupant in a three-point configuration. A lifting arm has a lowered position wherein it is beneath the belt and adjacent the latch when the latch is engaged with the buckle, and the lifting arm is movable to a raised position wherein it raises a portion of the belt to a position adjacent the back rest above the buckle, thereby creating a 4th belt attachment point.
