Power sliding door having a linear drive mechanism

摘要

A power operator assembly is provided for moving a sliding door between a sliding door of a motor vehicle between a closed position and an open position. The power operator assembly includes a guide rail fixedly secured to the motor vehicle and defining a rail length. A slide mechanism slidingly engages the guide rail. A drive is fixedly secured to the guide rail for selectively moving the slide mechanism along the guide rail in either direction. First and second cables each extend between the sliding door and the slide mechanism for moving the sliding door as the slide mechanism is driven along the guide rail. A compound pulley set is operatively connected to the drive and receives the first and second cables for powered movement of the sliding door a multiplied distance greater than the rail length as the slide mechanism is driven along the guide rail.
