Abstract: An actuator for a vent in a vehicle includes a motor actuated by a dashboard mounted switch. In a first embodiment, a slider is received for reciprocal linear movement along a guide track mounted adjacent the vent. A first end of an actuating arm is pivotally connected to the slider and a second end is pivotally connected to the vent. A drive cable is supported by a pair of pulleys mounted at opposite ends of the guide track. A DC permanent magnet motor is connected for rotating one of the pulleys in opposite directions. A capacitor is selectively connected by a relay for discharge through the motor to actuate the vent. A three position switch has a first position for charging the capacitor in a first polarity, a second position for charging the capacitor to an opposite polarity and a third position for energizing the relay to discharge the capacitor through the motor. A variable resistor is connected between the capacitor and the motor for controlling the motor by regulating the discharge rate of the capacitor. An electromagnetic clamp retains the actuating arm in an adjusted position. In a second embodiment, a mounting bracket mounted adjacent the vent includes an actuating arm having an arcuate gear segment in engagement with a drive gear. A servo motor is connected for rotating the drive gear in response to a dashboard mounted servo actuator. A solenoid stop pin or an electromagnetic clamp may be provided to maintain the actuating arm in an adjusted position.
