Abstract: A power actuation system for a motor vehicle closure panel includes a motor configured to rotate an input gear member that is configured to rotate an output gear member. The output gear member being coupled with a lever that is coupled to the closure panel. A clutch assembly configured for movement between a lever driving position whereat the lever is caused to pivot in response to rotation of the input gear member and a lever releasing position whereat the lever can pivot independent of the input gear member. The clutch assembly being biased into the lever driving position and having at least one roller configured to move out of a detent of the clutch assembly to move the clutch assembly from the lever driving position to the lever releasing position in response to a force applied to the closure panel.

Abstract: A power actuation system for a motor vehicle closure panel includes a motor operable to pivot a driven gear. At least one pawl assembly is operably supported by the driven gear for movement between a lever driving position, whereat the pawl assembly is positioned to pivot a lever coupled to the door to pivot the door concurrently with movement of the driven gear, and a lever releasing position, whereat the pawl assembly is positioned to permit free pivotal movement of the lever and door relative to the driven gear. The pawl assembly includes a roller engaged with the lever for rolling movement therealong during movement of the pawl assembly between the lever driving position and the lever releasing position, which results in minimal static and kinetic friction, thereby lending to reliable, low effort movement of the pawl assembly between the lever driving position and the lever releasing position.

Abstract: A load balancing mechanism for controlling concurrent operation of a pair of latches of a vehicle via a respective pair of links connecting the pair of latches to an actuator, the actuator for sharing by the pair of latches, the load balancing mechanism comprising: a housing for connecting to a body of the vehicle; a lever mounted to the housing at a pivot such that the lever is pivotable about the pivot; an actuator mounting point on the lever connecting the lever to the actuator, the actuator for rotating the lever about the pivot; and a load balancing element mounted on the lever at an axis and rotatable about the axis, such that each of the respective pair of links is positioned on opposite sides of the axis, said each of the respective pair of links for coupling to a corresponding one of the pair of latches; wherein operation of the actuator causes both rotation of lever about the pivot and rotation of the load balancing element about the axis while the pair of latches are operated concurrently.
