ABSTRACT:
A seat plate assembly intended more particularly for the driving seat of a commercial vehicle has a base portion and seat cushioning thereon. Between the base portion and the seat cushioning is a flat operating element with which a switching device can be actuated by way of an operatively interposed elongate actuating member for switching a functional device of the vehicle on or off in dependence on weight on the seat. The operating element is provided at its underside with at least one drive portion with which the elongate actuating member is displaced in its longitudinal direction towards the switch when the seat plate assembly is loaded with a weight, whereby the switch is actuated. Connected to the elongate actuating member is a spring which is mechanically stressed when said displacement movement occurs.
