Abstract: F-591 C-3995 COMPARTMENT PANEL PULL DOWN MECHANISM Mechanism for pulling an opened compartment panel closed and engaging a latch with a striker includes a slide member mounted on the body for horizontal reciprocating movement and having a cam slot which receives a cam follower carried by the striker so that horizontal reciprocating movement of the slide member vertically reciprocates the striker. The cam slot includes an inclined cam surface effective to provide the vertical reciprocation of the striker. The cam slot also includes a horizontal dwell surface at the end of the inclined surface to define the retracted position of the striker in which the compartment panel is closed so that the load imposed on the compartment lid in the direction to pry open the compartment panel is prevented from urging the slide member in a direction which would permit the striker to extend. A second horizontal dwell surface at the other end of the inclined surface defines the extended position of the striker so that a slamming movement of the compartment panel toward the closed position latching the latch with the striker is prevented from urging movement of the slide member in a direction to permit retraction of the striker. Thus, the pull down mechanism is constructed so that a vertical load imposed on the striker when the compartment panel is slammed or when the compartment panel is pried open is not exerted on the motorized drive unit.

Abstract: POWER SLIDING DOOR CLOSURE A sliding door in a van is mounted on tracks for sliding movement between open and closed positions. At the closed position a weather strip is compressed and a door latch is latched. A cable is attached to the door and routed through the vehicle body via pulleys so that pulling the first cable end opens the door and pulling the second cable end closes the door. A motorized drive mechanism includes first and second reels mounted concentrically and having the cable ends wrapped respectively about the reels in opposite directions. A motor drives in one direction rotating the first reel to open the door and is reversible to rotate the second reel to close the door. Each of the reels has a large diameter portion for winding the cable to provide relatively high speed and low force door movement over the greatest portion of travel and a small diameter portion for winding the cable to provide relatively low speed and high force movement of the door during the lesser portion of travel of the door closest to the closed position. The reels have cable seat grooves to receive the cable and a spiral ramp groove to connect the large and small diameter portions. A tension retaining spring acts between the two reels to always maintain the cable under tension.
