Remotely actuated rearview mirror for automotive vehicles
First Claim
1. A remotely actuated rearview mirror for an automotive vehicle, said mirror comprising, in combination, a reflective element having a full reflectance mode and a partial reflectance mode, eccentric cam means connected to said reflective element, means including unidirectional, rotatable DC motor means operable upon multiple revolutions thereof to drive said cam means and index said reflective element successively between said full reflectance and partial reflectance modes, means including manually actuatable switch means operable to initiate energization of said DC motor means, and additional switch means controlling the energization of said DC motor means, to de-energize said DC motor means when said reflective element is in either of its reflective modes.
