    摘要: A drive arrangement for a motor vehicle top having an outwardly movable sliding cover driven by an electric motor through a transmission and at least one threaded cable engaging a pinion of the transmission, a manually-actuated switch and a limit switch with a contact arm being provided in a circuit of the electric motor, the contact arm cooperating with a cam of a trip gear to interrupt the current supply to the electric motor in a closed position of the sliding cover, is improved by a construction of the indexing gear transmission for changing the operation of the drive arrangement in a manner increasing the time available for actuation of the limit switch independently of the degree of mobility of the top and ambient temperature conditions when the top reaches a position near the fully closed position. This change in the operation of the drive arrangement is achieved by gear constructions which extend the length of an indexing step just prior to closure or by changing the motor operating speed and thereby reducing the angular velocity of a limit switch actuating trip gear.
