A four point seat belt system includes a first seat belt and a second seat belt, each anchored at two points. A first retractor is coupled to the first seat belt proximate one of the anchor points and a second retractor is coupled to the second seat belt proximate one of the anchor points. A buckle releasably couples the first and second seat belts and the first and second retractors automatically retract the first and second seat belts to position the buckle at a point centered on a seat occupant's torso. The four point seat belt system can be operated using only one hand similar to a three point seat belt system.
