Abstract
The invention relates to a device for measuring the position of an object that can be moved forward and backward along a fixed path, such as a closure element of an open roof construction for a vehicle. The device includes a driving unit for the object and a pulse generator, which is driven by the driving unit, for delivering pulses during the movement of the object along the path. The device further includes a slow potentiometer, which potentiometer is likewise driven by the driving unit and which is connected to the driving unit via a transmission, such that the potentiometer passes through its range of values maximally once during a complete movement of the object along its fixed path. The slow potentiometer provides a monitoring function with respect to the position signal that is based on the number of registered pulses.
