Abstract
An electrically actuated rearview mirror comprises a mirror, a support housing and means for pivotally mounting the mirror on the support housing. The mirror is pivotal about mutually orthogonal X and Y axes. A sphere is mounted on the back of the mirror and is disposed inwardly of the housing on a rod extending through an aperture in the housing. The X and Y drive means are disposed within the housing and arranged to engage the sphere for pivoting the mirror about the X and Y axes, when electrical power is applied to the drive means. The X drive means comprises a first surface, slidably engaging and partially encompassing the sphere and the Y drive means comprises a second surface slidably engaging and partially encompassing the sphere. The first and second surfaces extend in mutually orthogonal directions. The first and second cylindrical surfaces of the X and Y drive means are disposed on slides which are reciprocally mounted for displacement in mutually orthogonal directions in the housing. The slides are provided with clutch mechanisms including follower springs biased into sliding engagement with helical tracks disposed on the output shafts of the X and Y drive means to provide for ratchet-like adjustment of the mirror relative to the housing in the event of a power failure or in the case where the mirror reaches an adjustment stop. A resiliently deformable boot extends between the back of the mirror and the housing to provide a flexible seal for the housing aperture.
