Abstract
An electrically actuated rearview mirror comprises a mirror, a support housing for the mirror and means for pivotally mounting the mirror in the support housing, the mirror being pivotable about mutually orthogonal X and Y axes. A spherical gear is disposed on the back of the mirror, the spherical gear including an X gear section and a Y gear section. The X and Y gear sections are provided with spherical pitch lines. X and Y drive means mesh with the X and Y gear sections for pivoting the mirror about the X and Y axes, respectively. The X and Y gear sections and the X and Y drive means are provided with gear teeth having a roughly triangular cross section and the X and Y drive means are spring biased into engagement with the X and Y gear sections, respectively, to provide for ratchet-like adjustment of the mirror relative to the support housing in the event of a power failure.
