Exterior rear view mirror - has motorised adjustment pivoting on spring-loaded ball joint released for manual adjustment

摘要

The mirror is contained in a rigid casing (1) fixed to the vehicle bodywork. This casing holds a mirror carrier (13) and an enclosed chassis (2) containing the motors and their linkage to the mirror carrier. The chassis has a cup-shaped opening (10) into which a spherical boss (12) attached to the mirror carrier fits. A spring assembly (20,21,22,23) holds the boss (12) in contact with its seat (10) and provides sufficient friction to hold the mirror securely in position against vehicle vibration. Two mirrors and drives move the mirror carrier in two mutually perpendicular axes. A motor (30) drives a toothed rod (26) through a sprocket (28). The rod is attached to an extension (16) of the spherical boss (12) and provides movement in one axis. A similar arrangement gives adjustment in the other axis.
