A drive for a movable furniture element has an actuating element for moving the furniture element and a motor for driving the actuating element. The actuating element and the furniture element may at times be moved independently of one another, and a position measurement system is provided for determining both the position of the actuating element and the position of the furniture element.

Drive for a movable furniture element

A sensor which is intended to detect the rotational position of a device (e.g. a shaft (21) or a rotatable hatch (20)) which is rotatable preferably by a motor (24) incorporates a position detector and a potentiometer (25). With a view to improving the latter's accuracy within part of the relevant rotation range of the device, a cam mechanism (2,5,8,30) is arranged between the potentiometer (25) and the rotatable device (20,21).
