Abstract: A drive assembly for a toothed rack and channel track type of power liftgate attaches the liftgate lift rod to the toothed rack indirectly, through a shoe-yoke assembly that transfers axial loads, but isolates the rack from non axial reactive loads transferred through the lift rod. A rigid yoke fits closely within axially spaced ends of a notch in the rack, but has a clearance elsewhere from the outside of the rack. The outside of the yoke is closely surrounded by a shoe, which provides a close fitting, slidable bearing layer with the inside of the channel track, maintaining the yoke to rack clearance. The maintenance of the yoke-rack clearance prevents the transmission of undesired reactive loads back to the rack through the yoke.

Abstract: An arrangement for automatic opening of a motor vehicle rear door which can be pivoted about a horizontal swivel axis contains a pneumatic spring-and-ejector combination in which a pneumatic spring is pivotally connected to the vehicle and the rear door so that it exerts a closing torque on the door when the door is in a closed and a predetermined partially open position, and exerts an opening torque when the door is opened beyond the predetermined position to swing the door fully open. An ejector is arranged to pivot the door from the closed position to a position past the partially open position, thereby reducing the energy requirement of the ejector and avoiding high frictional forces in the door lock.

Abstract: A connection wire is connected to a part of a rear door popped up in a door-opening direction by an urging force. A pulley rotates responsive to a driving motor inside a wire-winding device to wind the connection wire thereon. In this manner, the rear door is automatically closed. The pulley is urged in a connection wire-winding direction by a power spring. A clutch is between the pulley and the driving motor. When the rear door is pressed by an operator's hands in a door-closing direction while the rear door is being closed, the pulley is rotated by the power spring, thus winding the connection wire thereon and preventing the connection wire from becoming loose. At this time, the connection between the pulley and the driving motor is cut off by the clutch. Thus, the pulley is rotated by the power spring freely and rapidly. In this manner, the rear door can be closed manually even while it is being closed automatically.

In the closed mode of the assembly in which the barrier frame is nested in the main frame and is latched thereto, the window is then fully protected.

Abstract: A gate opening and closing apparatus, typically referred to as a "gate operator" and which automatically moves a gate, such as a swinging gate between opened and closed positions. The gate operator of the invention employs a power unit, such as an electrically motor driven power unit which rotates a power arm. A crank arm is releasably connected to the power arm and movable therewith. In addition, the crank arm is, in turn, connected to a connecting arm which has one end connected to the gate for movement of the gate.
