Patent number: 6561569Abstract: A passenger van is equipped with a drive mechanism for power operation of a slideable side door. The drive mechanism has a flexible drive cable that travels in a closed loop that includes cable portions that travel through a center track in opposite directions. The center track supports and guides a roller assembly that is attached to the rear of the side door. The roller assembly carries a cinch mechanism that selectively connects the roller assembly to a portion of the cable that is traveling in one direction to open the sliding door and that selectively connects the roller assembly to a portion of the cable that is traveling in the opposite direction to close the sliding door. The cinch mechanism is normally disconnected from the cable so that the side door can be opened or closed manually very easily.Type: GrantFiled: August 19, 2002Date of Patent: May 13, 2003Assignee: Delphi Technologies, Inc.Inventors: Bruce J.

Patent number: 6454339Abstract: Apparatus for opening and closing a deck lid of a vehicle body. An elongated rack is mounted in a housing for longitudinal movement. A rotatable pinion meshes with the rack to move the rack longitudinally in one direction or the other depending on the direction of rotation of the pinion. A reversible motor rotates the pinion in opposite directions. The deck lid is attached to a pair of arms pivoted to the vehicle body. A link has one end pivoted to the rack and the opposite end pivoted to one of the arms. The deck lid is moved to open position in response to longitudinal movement of the rack in one direction or to closed position in response to longitudinal movement of the rack in the other direction.Type: GrantFiled: January 8, 2001Date of Patent: September 24, 2002Assignee: Delphi Technologies, Inc.Inventors: Ronald James Wilde, John R. Rice, Lloyd Walker Rogers, Jr., David A. Sedlak

Patent number: 6406075Abstract: A latch handle assembly for permitting power or manual unlatching of a door latch. The assembly includes a latch handle for manual unlatching of the vehicle door. A mechanical linkage is attached to the latch handle and is adapted to interconnect with the door latch. The latch handle assembly also includes a switch disposed on the latch handle. The switch interconnects with a power-assisted unlatching mechanism that allows the switch to unlatch the door. Finally, there is a handle lock disposed adjacent the latch handle for disabling the latch handle in the normal condition when power is on and the power-assisted unlatching function is operable. The handle lock is operative to move from a locked position preventing the latch handle from moving, and an unlocked position allowing movement of the latch handle.Type: GrantFiled: December 30, 1999Date of Patent: June 18, 2002Assignee: Delphi Technologies, Inc.Inventors: John R.
