A mirror operating mechanism

摘要

An exterior rear view mirror has a mirror head (12) rotatably mounted on a spigot (11), which is secured to a mounting bracket (10). A detent (17) holds the mirror head (12) in a desired position relative to the mounting bracket (10). A spring (23) acts between the mounting bracket (10) and mirror head (12) to hold the detent (17) in its engaged position. An actuator (92, 95) is driven by an electric motor drive (82) so that, upon initial operation while the detent (17) is engaged to resist rotation of said mirror head (12) a force is applied to compress the spring (23), thereby causing movement of the mirror head (12) so that the detent (17) disengages. During subsequent operation, the actuator (92, 95) rotates said mirror head (12) about the spigot (11). <IMAGE>
