  • Patent number: 5154481
    Abstract: Vehicle roof with at least one cover that, alternatively, closes or at least partially opens an opening in a fixed roof surface of the vehicle, carries a solar power source for supplying power to at least one power consuming device that is separately located from the cover, and with a contact device for producing an electrical connection between the solar power source and the consuming device.

  • Patent number: 4420185
    Abstract: 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.
