1. Vorrichtung zum Überwachen des Verschleißzustands eines Reibbelags für Kraftfahrzeug-Scheibenbremsen, mit einem Reibbelagdickensensor, der mehrere und bei unterschiedlicher Dicke des Reibbelags ansprechende Verschleißelemente mit jeweils einer bei der entsprechenden Reibbelagdicke in ihrer Leitfähigkeit sprunghaft veränderten Widerstandsbahn besitzt, dadurch gekennzeichnet, dass die elektrische Zuleitung der Widerstandsbahn in ihrem außerhalb des Reibbelags gelegenen Bereich so beschaffen ist, dass sie durch den über die wirksame Fläche der Bremsscheibe hervortretenden Bereich der Bremsscheibe nicht beeinflusst wird.1.Device for monitoring the state of wear of a friction lining for motor vehicle disc brakes, with a friction lining thickness sensor which has a plurality of wear elements which are responsive and which respond to different thicknesses of the friction lining, each with a resistance path which has an abrupt change in conductivity with the corresponding friction lining thickness, characterized in that the electrical feed line the resistance track in its area located outside the friction lining is such that it is not influenced by the area of the brake disk protruding over the effective area of the brake disk. 2. Vorrichtung nach Anspruch 1, dadurch gekennzeichnet, dass die Verschleißelemente parallel und in gleichem oder unterschiedlichem Abstand zur Wirkfläche des Reibbelags angeordnet sind und dass jedes Verschleißelement an einer gemeinsamen Basis befestigt ist.2. Device according to claim 1, characterized in that the Wear elements parallel and at the same or different distance from Active surface of the friction lining are arranged and that each wear element is attached to a common base. 3. Vorrichtung nach Anspruch 2, dadurch gekennzeichnet, dass die Basis durch ein Blechstanzteil gebildet ist.3. Device according to claim 2, characterized in that the base is formed by a stamped sheet metal part. 4. Vorrichtung nach Anspruch 1, dadurch gekennzeichnet, dass die Verschleißelemente eine Drahtschleife enthalten.4. The device according to claim 1, characterized in that the Wear elements contain a wire loop. 5. Vorrichtung nach einem der Ansprüche 1 bis 4, dadurch gekennzeichnet, dass die Zuleitungen der Verschleißelemente parallel zueinander und schräg zum Verlauf in dem Bereich angeordnet sind, in dem die Verschleißelemente durch den Reibbelag beeinflusst sind.5. Device according to one of claims 1 to 4, characterized in that the leads of the wear elements parallel to each other and at an angle to Course are arranged in the area in which the wear elements through the friction lining are affected.
