<p>An operator presence sensor for an operator's seat (10) on equipment, such as skid steer loaders and the like, provides a signal to indicate when the seat is occupied. The operator presence is sensed by permitting seat rails (30) to pivot about their forward end against leaf springs designed to support the seat weight plus a known fraction of an operator's weight so that the rear of the seat is raised when the seat is unoccupied and when an operator occupies the seat the springs deflect and the rear of the seat moves down, resting on a seat support pan (14). An electronic sensor detects seat position to provide a position signal. <IMAGE></p> |
