Abstract
An occupant sensing apparatus for detecting a seated person on a seat includes a pressure switch disposed in the seat. The pressure switch has a pair of films and a pair of electrodes disposed between the films. The pair of electrodes are spaced in the films so as to define an OFF condition of the pressure switch. The pressure switch is in an ON condition when the electrodes contact each other. The occupant sensing apparatus further includes a controller connected to the electrodes of the pressure switch and determining whether the seat is occupied in accordance with the ON or OFF condition of the pressure switch.
