Abstract:
A power liftgate drive assembly (10) moves a liftgate (12) of a motor vehicle (14) between an open position and a closed position. The power liftgate assembly (10) is aligned along the side of the motor vehicle (14). A liftgate rod (46) extends in a generally vertical orientation between the power liftgate drive assembly (10) and the liftgate (12). The assembly (10) includes a base (24) that is fixedly secured to the motor vehicle (14) near a load floor (22). A guide (28) extends upwardly from the base (24). The guide (28) extends along the side of the motor vehicle (14) and is disposed adjacent the liftgate (12) when the liftgate (12) is in the closed position. A liftgate carriage (40) is connected to the guide (28). The liftgate carriage (40) slides along the guide (28). The liftgate rod (46) is pivotally connected between the liftgate carriage (40) and the liftgate (12). The liftgate rod (46) translates the linear movement of the liftgate carriage (40) into the pivotal movement of the liftgate (12) to move the liftgate (12) between the open and closed positions.
Abstract:
The present application discloses a power actuator for a latch assembly. The power actuator has a motor (70) having a rotatable motor output member (94) and a clutch assembly (50). The clutch assembly has a rotatable clutch output member (48). A stamped, cup-shaped ferromagnetic coil casing (126) has a generally radially extending base wall and an annular side wall extending generally axially from the base wall. An annular ferromagnetic flux intensifying washer (160) is positioned adjacent to the base wall of the coil casing. An annular coil of electroconductive material is operable to selectively generate a magnetic field. The coil (112-118) is disposed within the casing with the side wall extending in surrounding relation with respect to the coi l such that the field generated by the coil flows generally radially through the base wall and generally axially through said side wall. A ferromagnetic armature (120) is in sliding relation with the annular coil and movable between (a) an engaged position wherein the armature couple s the motor output member and the clutch output member together so that energization of the motor rotatably drives the clutch outpu t member and (b) a disengaged position wherein the motor output member and the clutch output member are uncoupled to enable the clutch outpu t member to rotate without resistance from the motor. Selective energizing of the coil effects movement of the armature between th e engaged and disengaged positions thereof.

Abstract:
A power liftgate drive assembly automatically moves the liftgate of a vehicl e between its open and closed positions. The drive assembly is secured to the vehicle at a position near the top of the liftgate. The drive assembly includes a motor that drives a sector gear between two positions. A guide ro d is secured to the sector gear to translate the rotational movement of the sector gear into the pivotal movement of the ligtgate. A slot extends throug h the sector gear that allows the liftgate to be moved manually. A latch locks the guide rod in position with respect to the sector gear for automated movement whereas the latch releases the guide rod to move in the slot for manual operation.
