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:
An anti-pinch assembly is used in combination with a closure device of a motor vehicle. The closure device includes a closure panel, i.e., a windowpane or door, and a motor for moving the closure panel between an open position and a closed position. In the closed position, the closure panel covers an aperture, i.e., a window or door opening, of the motor vehicle. The anti-pinch assembly includes a position sensor that is disposed adjacent the motor or the closure device. The position sensor generates a position signal indicative of the position of the closure panel. A capacitive sensor measures the capacitance of a field extending through the aperture. The capacitive sensor generates a signal therefrom. A controller is electrically connected to the position and capacitive sensors. The controller receives the position and capacitive signals and transmits a signal to the motor to prevent the motor from moving the closure panel toward the closed position when the output signals deviates from a series of predetermined values for more than a predetermined period of time.
Abstract:
A power drive mechanism (10) for a motor vehicle liftgate includes a linking arm (18) pivotally connected with the liftgate, a crank arm (12) drivable for pivotal movement and connected with the linking arm (18), and a gear train (20) operatively engaging the crank arm (12). A drive motor (34) is operatively connected with the crank arm (12) through the gear train (20) to provide power assisted opening and closing of the liftgate. The gear train (20) is disengageable from the drive motor (34) to permit manual opening and closing of the liftgate without backdriving the drive motor (34). An actuator (74) is operatively connected with the gear train (20) to move the gear train into and out of engagement with the drive motor. A holding linkage (60, 62) is operatively associated with the gear train (20) to maintain the gear train (20) in engagement during power assisted opening and closing of the liftgate.

Abstract:
A power sliding door (10) for a motor vehicle comprises a door structure, a power drive assembly, a latch assembly (22), and a single motor (108) for operating both the latch assembly (22) and the power drive assembly (14). The door structure is mounted on a track (204) associated with the motor vehicle, the door structure being movable along the track (204) between opened and closed positions. The power drive assembly (14) is connected with the door (10) and capable of being driven to move the door (10) along the track (204) between the opened and closed positions. The latch assembly (22) is mounted on the door (10) and movable between latched and unlatched positions. The single motor (108) is mounted on the door structure operatively connected with both the power drive assembly (14) and the latch assembly (22). The motor (108) drives the power drive assembly (14) and thus enables the power drive assembly (14) to move the door along the track between the opened and closed positions. The motor (108) assists movement of the latch assembly (22) to the latched position after the power drive assembly (14) moves the door (10) to the closed position.
