Abstract
A vehicle body compartment is closed by a closure panel movable between an open position and a closed position. A latch assembly has a latch bolt spring biased to an unlatched position and normally maintained in the latched position by a detent lever. A pull down mechanism includes a housing mounted on a vehicle body panel and mounting the latch assembly on the housing body for movement by a motorized vertically reciprocating drive unit between an extended position and a retracted position. When the closure panel is moved toward the closed position, a striker carried by the closure panel engages with the extended latch assembly to interconnect the closure panel with the latch assembly. The drive unit is energized and retracts the latch assembly, thereby pulling the closure panel to its fully closed position. To open the closure panel, the operator energizes the drive unit to move the latch assembly from the retracted position to the extended position. A cam lever associated with the latch assembly engages with a cam fixedly mounted on the housing during extending movement of the latch assembly by the drive unit to cam the detent lever to the position releasing the latch bolt, thereby freeing the closure panel for movement to the open position.
