Abstract
A power drive moves a movable closure along a fixed path between an open and a closed position with respect to a portal defining a passage through a barrier. The power drive system is adapted for a sliding door mounted on at least one side of a vehicle for sliding movement forwardly and rearwardly of the vehicle. The system includes a reversible motor operable when actuated to selectively drive the door in opening or closing movement. A bracket is connected to the door for movement with respect to a guide connected to the side wall of the vehicle. The bracket is guided within the guide along a fixed path between the opened and closed positions of the door. An elongated drive member is connected to the bracket at one end for driving the bracket along the fixed path. The elongated drive member is slidably disposed within the guide. A translator mechanism operably engages with the drive member for powering movement of the drive member and connected bracket with respect to the guide along the fixed path. The translator mechanism can include a rotatable hub, operably engageable with the drive member, a gear transmission for driving the hub, and a clutch mechanism for connecting the motor to the transmission. The translator mechanism preferably has sufficient power to pull the sliding door into a primary latch position with respect to the corresponding portions of a latch mechanism attached to the door and frame defining the door opening.
