1. An extendable exterior rearview mirror assembly comprising:

  • a mounting bracket for mounting to a vehicle;

    a mirror subassembly having a housing and a reflective element;

    a support arm mounted for pivotal movement on said mounting bracket from a normal operating position toward a folded position, said support arm having a longitudinal axis, said longitudinal axis extending laterally outward from the vehicle when said mounting bracket is mounted to a vehicle and said support arm is in said normal operating position; and

    a clamping assembly mounted in said housing, said clamping assembly comprising a biasing member and a bearing member, said mirror subassembly being mounted on said support arm by said clamping assembly for selective movement on said support arm along said longitudinal axis of said support arm to at least one extended viewing position spaced from a fully retracted position, and said biasing member providing a spring force, said spring force providing frictional engagement between said bearing member and said support arm to releasably clamp said mirror subassembly on said support arm to limit movement of said mirror subassembly along said longitudinal axis of said support arm, said support arm moving relative to said biasing member and said bearing member when a sufficient force is applied to said mirror subassembly wherein said mirror subassembly moves relative to said support arm along said longitudinal axis of said support arm to adjust the viewing position of said mirror subassembly.
