Abstract

A sun visor assembly has a rotatable friction mount including an elongated shaft receiving thereon an inner tubular friction member, two tubular spacers and a helical compression spring, all telescopically received within an outer tubular member and trapped between longitudinally-spaced apart retainer washers. Notches adjacent to the ends of the tubular friction member define hinged end portions which are tiltable under the urging of the compression spring radially outwardly into frictional engagement with the outer tubular member. A similar hinged tiltable end portion may be formed on one of the spacer members. Plural pairs of notches may be formed in the inner frictional member to define plural sets of hinged tiltable portions. In one embodiment the outer surface of the inner fricitonal member has longitudinal ribs disposed for ratcheting engagement with spring clips which project inwardly through apertures in the outer tubular member. A visor panel is secured to the outer tubular member and may be provided with a vacuum-formed recess for receiving an associated mirror, covered by a hingedly mounted cover on the visor panel.
