Vehicular mirror actuator with single motor actuation and inboard center of gravity and vehicular mirror incorporating the same
First Claim
1. A mirror assembly for a vehicle comprising:
- a base assembly for attaching the mirror assembly to the vehicle;
a support frame having an H-shaped cross section in at least a portion thereof, rotatably attached to the base assembly for rotation about a generally vertical axis and supporting a reflective element, the support frame having an inboard portion proximal to the base assembly and an outboard portion distal of the base assembly;
the reflective element having an inboard portion proximal to the base assembly, an outboard portion distal of the base assembly, and a generally vertical medial axis separating the inboard portion and the outboard portion;
a pivot connection provided substantially along the medial axis of the reflective element for movably coupling the reflective element to the support frame; and
an actuator attached to the inboard portion of the support frame, and operably coupled with the reflective element to provide adjustable movement of the reflective element about at least two axes.

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.
