Abstract
A rearview mirror tilt actuator comprises a clutch assembly that selectively transfers torque from an actuator motor to one of at least two output shafts based upon the speed of the motor. One output shaft can pivot the mirror about a first axis of rotation; another output shaft can pivot the mirror about a second axis of rotation. One output shaft can pivot the mirror housing; the other output shaft can extend and retract the mirror housing. At a low speed, the clutch assembly is disengaged, thus only the first output shaft is activated. At a high speed, the clutch assembly is engaged, thus both output shafts are activated The mirror assembly described herein also has an improved mass configuration which allows for lower moments of inertia in the direction of mirror travel.
