Abstract
A door actuation system conducts or assists movement of sliding vehicle doors by connecting the door to a bi-directional motor via one or more helical cables that engage with gearing on the bi-directional motor. Rotation of the motor in either direction pushes or pulls the helical cables, causing the door to move toward the open or closed position. The motor can be stopped when the door reaches selected positions other than the open or closed position, holding the door in a partially open position.
