Vehicle rearview mirror assembly |
摘要 |
A day/night vehicle rearview mirror assembly comprises a casing carrying a prismatic mirror, the casing being pivotally mounted on a mounting plate. Preferably, the casing and mirror are driven between a full reflectance position and partial reflectance position by a rack and pinion assembly having interengaging gear teeth extending between a d.c. motor operated drive shaft and a portion of the casing. Alternately, a friction coupling extends between the drive shaft and casing. A noise and vibration reducing coupling are provided in the drive shaft while appropriate glare sensing circuitry and/or switches control operation of the reversible motor and, thus, the reflectance position of the mirror.
