Abstract
A powered actuator (1) for driving mechanisms that open and close convertible tops, sunroofs, windows and the like in motor vehicles; in which actuator (1) has a manual override feature allowing actuator (1) to be easily operated by hand should the electrical power system of the motor vehicle fail, yet the manual override feature does not require calibration or periodic adjustment. Actuator (1) includes actuator housing (2) having an attached motor having first gear (28) driven by the motor armature, output shaft (18) having driven gear (12) mounted thereon, insert cushion (10) being engaged with driven gear (12), and removable plate (6) being installed upon plate end (42) of output shaft (18). Actuator (1) is manually operated by removing removable plate (6) thereby disengaging driven gear (12) from output shaft (18) and then manually imparting rotation to plate end (42) of output shaft (18). Because driven gear (12) is disengaged from output shaft (18) in the manual mode, the motor armature does not resist the manually imparted rotation of output shaft (18).
