ABSTRACT:
A rearview mirror assembly comprises a mirror unit, a mirror unit support, and a central connection between the mirror unit and support mounting the mirror unit for pivotal movement about first and second generally intersecting perpendicular axes. A first arm is mounted on the support for pivotal movement about the first axis and connected with the mirror unit for limited pivotal movement about the second axis at a position spaced from the first axis. A second arm is mounted on the support for pivotal movement about the second axis and connected with the mirror unit for compound movement for compound movement which includes limited lateral movement with respect to the first axis and pivotal movement about an axis which is either coincident with or slightly angularly related with the first axis depending upon the position of relative lateral movement. First and second power-transmitting surfaces on the first and second arms respectively are arcuate about the first and second axis respectively. First and second power-operated rotary members are constructed and arranged with respect to the first and second power-transmitting surfaces respectively (1) to move under power in peripheral rolling contact therewith to effect movement of the first and second arms respectively and (2) to move under power in peripheral sliding relation therewith in the event that movement of the first and second arms respectively is otherwise prevented.
