Abstract
A clutch assembly having a driver, an output member, a clutch spring, an armature and an actuator. The clutch spring includes a plurality of coils that are configured to be drivingly engaged with the driver. The clutch spring further includes first and second ends. The first end is configured to drivingly engage the output member to facilitate the transmission of rotary power from the driver, through the clutch spring and into the output member. The second end is engaged to the armature. The actuator is selectively operable for rotating the armature relative to the driver in a rotational direction opposite a predetermined rotational direction in which the driver is driven to thereby initiate at least partial disengagement of the coils of the clutch spring from the driver.
