ABSTRACT:
A seat base assembly for the operating seat of a utility vehicle comprises a base portion, a seat cushion thereon, and between the base portion and the seat cushion a switching device for switching on and off an electrical circuit of an operating device of the vehicle. A plate-like surface element is mounted to the base portion by at least one resilient connecting portion and projects away from the base portion inclinedly at an acute angle. The switching device is arranged in the area of projection of the surface element on to the base portion at a spacing from the connecting portion, whereby movement of the surface element towards the base portion under the effect of the operator's weight on the seat actuates the switching device.
