Abstract

An interior rearview mirror assembly for vehicles incorporates a rearview mirror housing assembly having a polymeric rearview mirror housing and a reflective mirror element, a polymeric rearview mirror support, a polymeric rearview mirror mount, and first and second polymeric ball pivot members received in respective sockets allowing pivotal adjustment of the rearview mirror housing assembly. At least one electrical conductor connects an electrical accessory in the mirror housing assembly to the vehicle electrical system. The rearview mirror support includes a cable-way such that the presence of the electrical conductor as it passes through the ball pivot members and the cable-way is concealed from view while being protected therein even while the ball pivot members are pivoted for adjustment. The various polymeric elements of the assembly are preferably molded in the same color such as black, or alternately in at least two different colors.
