  • Patent number: 6369537
    Abstract: A device for displacement of a movable part on motor vehicles such as sliding roofs, windows or the like including an electrical servomotor permanently mechanically coupled to the movable part and a supply circuit adapted to operate the electrical servomotor and to brake the electrical servomotor by short circuiting the electrical servomotor when the movable part reaches a desired position, where the supply circuit includes an isolating device for breaking the supply circuit to prevent short circuit braking of the electrical servomotor thereby allowing manual displacement of the movable part.

  • Patent number: 5793173
    Abstract: An actuation device for motor vehicle parts that are movable by an electric motor, in particular for window regulators and sliding roofs that are driven by a reversible electric motor. This actuation device has a setpoint value device for the desired position of the movable part, an incremental actual-value device for producing a signal corresponding to the actual position of the movable part, an absolute actual value device which emits first and second signals that are positionally fixed relative to the incremental actual-value device, and a microprocessor to compare the setpoint and actual value signals and to perform control and regulation programs. The signal emitted by the absolute actual-value device changes only at predetermined position values and the absolute actual-value device has position zones which are separated from one another by these position values that can be predetermined. The first and last position zones are each defined by a first or second end position of the movable part.

  • Patent number: 5768942
    Abstract: Drive device for a part of a motor vehicle which can be moved between end positions, with an electric motor which is joined via a reducing gear to a driving pinion which sits on a driven shaft, and which for its part is drive-connected to the displaceable part, and with an electrical circuit which has switching means and which controls the motor for shutting off the motor in a predetermined position of the displaceable part. The reducing gear and electrical circuit are accommodated in separate housing parts which are detachably joined to one another to enable flexible matching to different circuit layouts. The gear housing part is produced as a metal die casting and the electric housing part as an injection molded plastic part.

  • Patent number: 5673590
    Abstract: A drive device for a part of a motor vehicle which can be moved between end positions, especially for a movable cover of a vehicle roof, with an electric motor which is joined via a reducing gear to a driving pinion which sits on a driven shaft that is drive-connected to the movable part, and with a switching means which controls the motor for shutting off the motor in at least one predetermined position of the movable part which is actuated by a ratchet wheel which is caused to rotate less than 360.degree.

  • Patent number: 5566593
    Abstract: A drive device for a vehicle part that can be displaced between end positions, especially for a cover of an openable vehicle roof. The drive device is actuated by an electric motor that is connected, by a reduction gear, to a pinion gear placed on an output shaft. The drive device further has a switch element controlling the electric motor, to stop it in at least one predetermined position and an eccentric gear arrangement is provided to actuate the switch. The drive device enables an emergency actuation in which manual actuation of the output shaft is made possible by uncoupling of the electric motor while maintaining the coupling of the switching gear elements, so that, after an emergency actuation, no readjustment of the switching arrangement is necessary.
