Abstract

A reduced vibration day/night rearview mirror assembly provides improved stability of the mirror assembly. The assembly preferably includes a molded mirror case, a prismatic mirror element, and a two piece actuator assembly which provides reduced vibratory movement between a mirror mounting bracket and the mirror assembly. The actuator assembly includes a toggle member and a pivot lever which pivotally interconnect. The toggle member has a pivot journal defined along at least a portion of a first side and has a pivot surface defined along at least a portion of a second, opposing side. The pivot lever has a pivot shaft for pivotally mounting the lever in the mirror case and has an open-sided pivot channel generally parallel to and spaced from the pivot shaft for receiving and pivotally engaging the pivot surface of the toggle member. The case has cooperating supports for receiving the pivot lever pivot shaft and a pivot axle for engaging the toggle member pivot journal. In one aspect of the invention, the pivot axle is noncircular in cross section and is preferably generally square. In another aspect of the invention, the pivot journal is a slightly tapered, open-sided channel having a noncircular cross section and is preferably wider across the open side than at an opposing side.
