A vehicle body compartment is closed by a closure panel movable between an open positiion and a closed position. A latch assembly mounted on the panel 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 and a striker mounted thereon by a motorized vertically reciprocating drive unit for moving the striker between extended position and a retracted position. When the panel is moved toward the closed position, the latch bolt engages with the extended striker to interconnect the panel with the striker. The drive unit is energized and retracts the striker, thereby pulling the panel to its fully closed position. To open the panel, the operator energizes the drive unit to move the striker from the retracted position to the extended position. A plunger is mounted on the latch assembly and engages with the vehicle body so that progressive opening movement of the panel by the extension of the striker permits a spring to extend the plunger. A cam device acts between the plunger and the detent lever of the latch assembly to cam the detent lever to the position releasing the latch bolt, thereby disconnecting the panel from the striker and freeing the panel for movement to the open position.

In a vehicle body including a closure panel mounted for movement between open and closed positions with respect to a compartment defined by a body panel, a latch and pull down mechanism comprising: a latch assembly mounted on one of the panels and having a latch bolt spring biased to an unlatched position and a detent lever for holding the latch bolt in the latched position; a striker assembly mounted on the other panel and adapted for engagement by the latch bolt of the latch assembly to latch the striker assembly to the latch assembly; a pulldown mechanism mounting one of the assemblies on its associated panel and having a motorized drive unit for moving the one assembly between an extended position where the striker and the latch bolt are engageable together upon partial closing movement of the closure panel, and a retracted position in which the latch assembly and the striker assembly cooperate to establish the closure panel in the closed position; means adapted to operate the motorized drive unit to move the one assembly to the retracted position to pull the closure panel to the closed position in response to latching engagement between the striker assembly and the latch bolt; remote opening means actuatable by the user for selectively operating the motorized drive unit to move the one assembly toward the extended position so that the closure panel is moved in the opening direction; and cam means acting in response to motorized movement of the one assembly from its retracted position toward its extended position to cam the detent lever to a position releasing the detent lever from the latch bolt, said cam means including a plunger movably mounted on the latch assembly and projecting into engagement with the other panel when the closure panel is in the closed position and spring means urging extension of the plunger so that the plunger is extended relative the latch assembly upon opening movement of the closure, whereby the latch bolt is spring biased to the unlatched position thereby disconnecting the latch assembly from the striker and freeing the closure panel for spring-loaded movement to the open position.
