Abstract
A remotely controlled rearview mirror assembly has a tiltable reflective member mounted on a fixed base in a casing, the reflective member being tilted by means of a remote control. Two or three-wire cable systems are the preferred linkage but electrical or fluidic linkages may be used. The reflective member is anchored to the base by a forked member to prevent rotation of the reflective member, in its own plane, which would otherwise cause jamming or juddering by contact with the sides of the casing. The preferred forked member is a V-shaped wire strut with arms pivotally attached to the reflective member and a necked junction part as a frictional pivot to provide damping. The reflective member is tiltably mounted by an arcuate knife edge received in a linear groove, the included angle of the groove being greater than that of the knife edge. This provides a substantially common elevational and azimuthal pivot point closer to the surface of the reflective member.
