Mirror actuator assembly with modular positional memory device
First Claim
1. A vehicular rearview mirror assembly, comprising:
- a frame;
a reflective element attached at the frame for providing an occupant of the vehicle with a rearward view;
a motorized tilt actuator adapted for selectively tilting the reflective element relative to the frame; and
a positional memory element located away from the tilt actuator coupling the frame with the reflective element, wherein a position of the reflective element relative to the frame is correlated to an output signal from the positional memory element so that movement of the reflective element from a first position to a second position results in a change in said output signal.

Abstract
A rearview mirror for a motor vehicle comprises an internal frame supporting a reflective element and a motorized tilt actuator assembly for adjusting the reflective element about perpendicular axes. The reflective element is attached to the internal frame through a pivot connection. A positional memory module comprising a separate assembly is supported by the internal frame adjacent the pivot connection for electrically determining the horizontal and vertical tilt of the reflective element at a selected position as a change in voltage through a pair of simple electrical circuits. The reflective element can be returned to the selected position by adjusting the horizontal and vertical tilt of the reflective element according to the changes in voltage.

17. A vehicular rearview mirror assembly, comprising:
-
a frame; a reflective element attached to the frame for providing an occupant of the vehicle with a rearward view; a motorized tilt actuator adapted for selectively tilting the reflective element relative to the frame; and a positional memory element contained within a modular housing located away from the tilt actuator coupling the frame with the reflective element, wherein a position of the reflective element relative to the frame is correlated to an output signal from the positional memory element so that movement of the reflective element from a first position to a second position results in a change in said output signal; wherein the modular housing containing the positional memory element can be selectively coupled to and decoupled from the frame and the reflective element without requiring disassembly of the tilt actuator. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29)
