ABSTRACT:
A power release and pull-down unit particularly adapted for rear compartment panels of motor vehicles. An electric motor rotationally drives a planetary gear set which in turn drives a latch hook. Limit switches are provided to sense the position of the latch hook such that motor rotation stops once the hook reaches one of two dwell positions. A clutching mechanism is provided to prevent excessive torque from being exerted on the latch hook during panel closure. When the panel is closed against the power unit, the latch hook is moved downwardly to securely close the panel against its sealing gaskets. Movement of the latch hook stops once a cam lobe contacts a limit switch. When the operator wishes to open the panel, motor rotation occurs causing the latch hook to move upwardly and out of engagement with the panel latch striker bar. In this mode, the latch box continues to move until it is in an upwardly extending dwell condition where rotation of the motor again stops through contact between another cam lobe and the limit switch. The unit therefore performs both remote release and pull-down functions and uses an unidirectional drive motor.
