Modular seatbelt minder

摘要

A vehicle restraint occupant sensing system is provided for detecting a presence of an unrestrained vehicle occupant in a vehicle seat. A seat belt restraint sensing circuit senses whether a seat belt is in an unlatched condition. An occupant sensing system includes at least one sensor assembly in spaced relation to a vehicle seat for sensing a presence of the occupant in the vehicle seat. The occupant sensing system includes a comparator circuit coupled to the at least one sensor assembly and the seat belt restraint sensing circuit for producing an output signal indicative of the presence of the occupant. A logic circuit is disposed within the vehicle seat coupled to an output of the comparator circuit and the seat belt restraint sensing circuit for providing an alert output signal when the seat belt is in the unlatched condition and the output signal indicates that the occupant is present.
