Pivot support for adjustable rearview mirror

An adjustable support for a reflective mirror element in a housing of a rearview mirror assembly provides improved control and more uniform movement of the reflective element. The adjustable support includes an adapter member, which supports the reflective element, a fixed member, and at least one member urging the adapter member into bearing contact with the fixed member. One of the adapter member and the fixed member includes an arcuate bearing surface, for example a semi-spherical bearing surface, and the other of the adapter member and the fixed member includes an annular line bearing surface which engages on the arcuate surface forming an annular line bearing contact between the adapter member and the fixed member to permit adjustment of a reflective mirror element in the housing. The adjustable support may comprise a handset with adjustable support, a remotely manual adjustable support, or an electrically actuated electrical adjustable support. Preferably, the line bearing contact is provided by a cylindrical member which extends from one of the adapter member and the fixed member with a line bearing surface being defined by the distal or free end of the cylindrical member.
