Abstract
Seat belts in a vehicle are monitored, and a reminder is initiated in response to a restraint sensor indicating the engaged or nonengaged state of a seat restraint, a vehicle sensor indicating when the vehicle is in use, an annunciator controllably producing a reminder, and an electronic control controlling the annunciator. The reminder is produced when the seat restraint is in a nonengaged state after having been an engaged state while the vehicle is in use. Thus, monitoring of the continued buckling of a seat belt, especially a rear seat belt, is provided without need for seat occupancy sensors.
