Abstract
The present invention is directed to a vehicle seat assembly comprising a seat support pan, a seat cushion, a spring biased lever and an operator present switch. Both the lever and the switch are located between the cushion and the pan, effectively integrated within the seat. The lever is movable between upper and lower positions, with its associated spring biasing the lever toward its upper position. The switch is designed and located so that all of its components are housed within the support pan and none of these components extends below or outside of the pan. When the seat is occupied, the occupant's weight depresses the cushion and, in turn, the lever moves against the force of the spring toward its lower position and the switch is actuated. Because the switch is located completely within the seat cushion, the seat assembly's vertical dimension or envelope is minimized and the design of the seat support and/or suspension located below the seat pan is simplified.
