Abstract

A wiper blade is proposed which is used to clean windows, especially of motor vehicles. The wiper blade is displaceable transversely to its length, preferably about a pendulum axis, and can be pressed with an elongated, rubber-elastic wiper strip (46) against the window (54) to be wiped; the wiper strip is disposed on the lower band face (49), oriented toward the window, of a bandlike-elongated, spring-elastic support element (42). Chattering that occurs during wiping operation and causes an unsatisfactory outcome of wiping as well as considerable noise, is avoided if the region of the upper band face (43), remote from the window, of the support element (42), the wiper blade is provided with a mass body, which is disposed movably, at least in the displacement direction (74) of the wiper blade.
