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.
A wiper blade for cleaning windows, in particular of motor vehicles, which transversely to its length is preferably displaceable about a pendulum axis and which can be pressed, with an elongated, rubber-elastic wiper strip (46), against the window (54) to be wiped, and the wiper strip is disposed on the lower band face (49), oriented toward the window, of a bandlike-elongated, spring-elastic support element (42), characterized in that in 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 (60, 160, 260, 360, 460, 560, 660, or 760, respectively), which is disposed movably, and in particular tiltably, at least in the displacement direction (74) of the wiper blade.
The wiper blade of one of claims 4 or 5, characterized in that the mass body (60, 160, 360, or 460, respectively) has an at least approximately triangular cross section.
The wiper blade of one of claims 4-7, characterized in that the spoiler (360) or (460) comprises a different material from the wiper strip (346) that is fabricated jointly with it and solidly connected to it.
The wiper blade of claim 8, characterized in that the wiper strip has a base body (64), which on a side remote from the window (54) changes over via the extension (68) to the spoiler (60, 160, 260, 360, or 460, respectively);
The wiper blade of claim 10, characterized in that viewed in cross section, the extension (68) of the wiper strip changes over, at the upper band side of the support element, into a bandlike base strip (70), with which the hollow body (600 or 700), comprising a different material but fabricated jointly with the wiper strip, is solidly connected via an articulated strip (72) formed by longitudinal grooves (71) that are laterally open at the edges.
The wiper blade of claim 11, characterized in that the mass body (760) comprises a different material from the wiper strip that is fabricated jointly with it and solidly joined to it.
