Abstract

A power actuator for a latch of a motor vehicle closure panel has an electric motor to rotate a lead screw about an axis. A nut is disposed about the lead screw for selective translation along the lead screw. A clutch plate is configured for selective rotation about the axis when engaged with the nut, with a biasing member biasing the nut out of engagement with the clutch plate when the electric motor is de-energized. A carrier member is coupled with the nut to cause the nut to translate into engagement with the clutch plate during rotation of the lead screw, whereupon the nut and carrier member co-rotate with the clutch plate and leadscrew. A driven member is operably coupled with the clutch plate and with the latch via a cable/rod, such that the driven member maintains the latch in a cinched state when the electric motor is energized.
