Abstract
A device for motorized opening and closing of pivotable body panels of motor vehicles, especially the rear trunk lid or rear hatch and/or the hood of automobiles, has a motor-actuated lever system engaging in an articulated manner, on the one hand, with the body panel, and on the other hand, with the body. The body end of the lever system is articulated at a slide block guided slidingly in a guide track. The slide block is operatively connected to a driver that is secured to a control cable. The ends of the control cable can be wound onto or off a common cable pulley actuated by an electric motor.

In an automotive vehicle having vehicle body structure and a body closure panel pivotally connected to the body structure for movement between open and closed positions, and a reversible power operated lever system operatively connected with the body structure and said body panel for effecting movement of said body panel between its positions, the improvement being that said lever system comprises a stationary guide track supported by said body structure, a slide block slidably and guidably supported by said guide track for movement in opposite closure panel opening and closure panel closing directions, a lever having one end pivotally connected to said slide block and its other end pivotally connected to said body panel and a reversible power operated drive means including a control cable and a driver attached to the cable, said driver being engageable with said slide block to positively move the same in said closure panel opening direction to effect opening movement of said body panel when the drive means is energized to move the cable in said closure panel opening direction, said driver being releasable from said slide block when the drive means is energized to move the cable in said closure panel closing direction, said slide block moving in the closure panel closing direction to effect sloping movement of said body panel due to the weight of said body panel and lever as said cable and driver are moved in said closure panel closing direction.
