Abstract: A power closure actuator for powering a movable closure includes a shaft situated between an electric motor and an output member. A brake device along the shaft is actuable via an electric brake actuator to apply braking. An active brake clamp is movable by the electric brake actuator. An axially floating rotor is rotatable with the shaft and has a first axial side facing the active brake clamp a second axial side providing a second braking surface. A passive backing brake clamp is positioned adjacent the second braking surface. The axially floating rotor is biased away from the passive backing brake clamp by a first biasing member. Deflection of the first biasing member coupled with axial movement of the active brake clamp and the axially floating rotor enables braking by pinching action of the axially floating rotor between the active brake clamp and the passive backing brake clamp.

Abstract: A power closure actuator for powering a movable closure includes an output member configured to drive movement of the movable closure, a motor coupled through a gear reduction to drive the output member, and an integrated brake-clutch unit having an input configured to receive drive power from the electric motor. The brake-clutch unit provides independent braking and clutching between the electric motor and the output member via an electric brake actuator and an electric clutch actuator, respectively. Brake and clutch portions of the brake-clutch unit act on a rotor, and brake force can be maintained on the rotor without powering the brake actuator. A clutch disc is biased disengaged from the rotor. The integrated brake-clutch unit provides a drive state between the electric motor and the output member when the brake portion is released concurrently with the clutch portion establishing a power coupling between the clutch disc and the rotor.

Abstract: An actuator for opening and closing a decklid or other closure on a motor vehicle is described and shown. The actuator can include a motor, a rod coupled to and driven by the motor, a first sleeve coupled to and driven by the rod, and a second sleeve coupled to and driven by the first sleeve. The first and second sleeves can be slidably coupled to one another, and/or can be rotatably locked relative to one another.

Abstract: An automotive vehicle has a power operated lift-gate that is opened and closed by two drive units. The typical drive unit has a guide channel, an attachment assembly that is disposed in the guide channel, a flexible drive member that is attached to the attachment assembly and formed in a loop for moving the attachment assembly in the guide channel. The flexible drive member is trained solely around two pulleys at the respective opposite ends of the guide channel to form the flexible drive member in a narrow loop. One of the pulleys is an idler pulley that is part of an adjustable pulley assembly and the other pulley is driven by a power unit that is attached to the guide channel. The adjustable pulley assembly adjusts the distance between the pulleys to take up slack in the flexible drive member.

Abstract: A two position spring biased lever system has a lever that pivots on a support between a first position and a second position, and a torsion spring. The torsion spring has a spring arm that is attached to a central coil at one end and that has an opposite distal end that is engaged in a notch of the lever. The torsion spring is stressed so that the spring arm biases the lever toward the second position while holding the lever in the first position when the distal end is in the notch. The spring arm moves the lever to the second position when the distal end is disengaged from the notch.
