Abstract
A seat belt system for a vehicle comprises a first seat belt buckle mounted at a first location, a second seat belt buckle mounted at a second location and a seat belt retractor mounted at a third location, a seat belt and a circuit. The third location is spaced along a seat for an occupant from the second location. The seat belt is extendable from the seat belt retractor and has a tongue. The seat belt is extendable to connect the tongue to the first seat belt buckle or the second seat belt buckle. The circuit interconnects the first seat belt buckle, the second seat belt buckle and the seat belt retractor. The circuit is configured to change an operating mode of the seat belt retractor when (1) the seat belt tongue is removed from the first seat belt buckle and/or (2) the seat belt tongue is removed from the second seat belt buckle. An optional indicator can be provided to indicate to the vehicle operator that the operating mode of the retractor has been changed.
