Abstract
A power-folding vehicle mirror assembly having an improved clutch assembly is disclosed. The assembly comprises: a base mountable to a vehicle; a clutch body mounted to and rotationally fixed to the base; a sun gear slidably mounted to the base for rotation, the sun gear biased towards engagement with the clutch body by a spring; a mirror head assembly rotatably mounted to the base; a planetary worm gear mounted to the mirror head assembly for rotation, the planetary gear meshing with the sun gear; and a motor for driving the mirror head assembly around the sun gear. Upon the application of a manual breakaway force to the mirror head assembly, the planetary gear transmits a breakaway torque to the sun gear. This causes the gear to slide away from and out of engagement with the clutch body, thereby allowing rotation of the sun gear and mirror head assembly with respect to the base while maintaining mesh with the worm gear. The clutch mechanism disclosed will have numerous other applications.
