Abstract

An exterior rearview mirror for a motor vehicle has a mirror housing, a wiper motor, and a wiper arm which is driven by the wiper motor via a wiper mechanism and bears a wiper blade for cleaning a mirror surface. The wiper mechanism generates an essentially parallel reciprocating movement of the wiper blade. It is essential here to the invention that the wiper mechanism has a first L-shaped pivot arm and a second L-shaped pivot arm which are respectively mounted rotatably in a fixed position at their elbows and are mounted rotatably, at their limbs on the wiper side, on an inner parallel wiper arm. Furthermore, an outer parallel wiper arm which is connected to the inner parallel wiper arm and bears the wiper blade is arranged on the inner parallel wiper arm. The two pivot arms are driven by the wiper motor to which they are connected in terms of drive at their limbs on the drive side.
