Power liftgate arm assist assembly
First Claim
1. A power liftgate assembly for a liftgate of a vehicle, said assembly comprising:
- a power drive unit;
a plurality of driven gears being selectively driven by said power drive unit;
a first drive arm adapted to be pivotally coupled to the vehicle;
a second drive arm adapted to be pivotally coupled to the liftgate of the vehicle at a first end thereof and pivotally coupled to said first drive arm at a second end thereof; and
an engaging device being selectively coupled to at least one of said plurality of driven gears, wherein said engaging device rotates an extension arm to engage said at least one driven gear into driving connection with said first drive arm, said engaging device rotates said extension arm in an opposite direction to disengage said at least one driven gear from said first drive arm to enable said first drive arm to actuate freely.

Abstract
A power liftgate assembly for a liftgate of a vehicle having a power drive unit and a plurality of driven gears. The plurality of driven gears is selectively driven by the power drive unit. The assembly further includes a first drive arm pivotally coupled to the vehicle and a second drive arm pivotally coupled to the liftgate at a first end and pivotally coupled to the first drive arm at a second end. The liftgate assembly still further includes an engaging device selectively coupled to at least one of the plurality of driven gears. The engaging device engages at least one driven gear with the first drive arm, thereby enabling the driven gear to drive the first drive arm. The engaging device is positionable between an engaged and a disengaged position, wherein the engaging device is operable in the engaged position to engage the driven gear into driving connection with the first drive arm. The engaging device is also operable in the disengaged position to disengage the driven gear from the first drive arm to enable the first drive arm to actuate freely.

7. A power liftgate system for a vehicle, comprising:
-
a liftgate adapted to be pivotally attached to the vehicle, said liftgate being positionable in an opened or closed position; a pneumatic actuator being coupled between a cargo opening of the vehicle and said liftgate, said actuator biasing said liftgate in said opened position; a power drive unit mounted to the vehicle; a plurality of driven gears being selectively driven by said power drive unit; a first drive arm adapted to be pivotally coupled to the vehicle, said plurality of driven gears driving said first drive arm; a second drive arm being pivotally coupled between said liftgate of the vehicle and said first drive arm; and an engaging device being selectively coupled to at least one of said plurality of driven gears, wherein said engaging device pivots an arm to engage said at least one driven gear into driving connection with said first drive arm, said engaging device pivots said arm in an opposite direction to disengage said at least one driven gear from said first drive arm to enable said first drive arm to actuate freely. - View Dependent Claims (8, 9, 10, 11)
