ABSTRACT:
A weight sensor (10) for sensing a load applied to a vehicle seat (14) includes a light source (16) for providing light and detectors (18, 20, 22, 24) for detecting light received from the light source (16). A member (50, 52, 54, 56) impedes the passage of light between the light source (16) and the detectors (18, 20, 22, 24) in response to the load applied to the seat (14). The light detectors (18, 20, 22, 24) provide a signal to a control device (27) indicative of the amount of light received. In response to the light detector signals, the control device (27) determines a value in accordance with the load applied to the seat (14).
