First Claim
1. A rearview mirror assembly comprisinga mirror unit having a mirror side and an opposite side,a mirror unit support disposed in facing relation to the opposite side of said mirror unit,a central connection between the opposite side of said mirror unit and said support mounting said mirror unit on said support for pivotal movement about first and second generally intersecting perpendicular axes,a first arm mounted on said support for pivotal movement between limits with respect to said support about said first axis and connected with the opposite side of said mirror unit for limited pivotal movement with respect to said mirror unit about said second axis at a position spaced from said first axis,a second arm mounted on said support for pivotal movement between limits with respect to said support about said second axis and connected with the opposite side of said mirror unit for compound movement with respect to said mirror unit at a position spaced from said second axis which compound movement includes limited lateral movement with respect to said first axis and pivotal movement about an axis which is either coincident with or slightly angularly related with said first axis depending upon the position of relative lateral movement, anda remotely controlled power-operated mechanism carried in part by said support for effecting a desired movement of said mirror unit together with a corresponding movement of either one or both of said first and second arms with respect to said support in response to a remote manual movement by a user,said remotely controlled power-operated mechanism including first and second power-transmitting surfaces on said first and second arms respectively arcuate about said first and second axis respectively, and first and second power-operated rotary members being annular in cross-section and engaged with said first and second power-transmitting surfaces respectively, said first and second power-transmitting surfaces being substantially smooth and said first and second power-operated rotary members having substantially smooth peripheral surfaces,said first and second power-operated rotary members being constructed and arranged with respect to said 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.

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.
