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.

What is claimed is: 1. A wiper blade for cleaning windows of motor vehicles, which transversely to its length is 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 ), wherein 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 freely movably, and in particular tiltably, relative to the wiperstrip and support element at least in the displacement direction ( 74) of the wiper blade, to surpress chattering motion of the wiper blade wherein the support element (42) has two spring rails ( 41), spaced apart from one another and extending parallel to one another and disposed in the same plane, wherein the wiper strip, over at least a part of its length, extends with an extension (68) through a gap between the two spring rails, wherein at least one mass body ( 60, 160, 260, 360, 460, 560, 660, or 760, respectively) is disposed on the extension, wherein the wiper strip has a wiper lip connected via a tilting rib below the support element, wherein the at least one mass body is a spoiler, and wherein the spoiler comprises a different material from the wiper strip that is fabricated jointly with it and solidly connected to it. 2. The wiper blade of claim 1, wherein the mass body ( 60, 160, 260, 360, 460, 560, 660, or 760, respectively) is embodied in striplike fashion and extends in the longitudinal direction of the support element ( 42). 3. The wiper blade of claim 1, wherein the mass body ( 60, 160, 360, or 460, respectively) has an at least approximately triangular cross section. 4. The wiper blade of claim 1, wherein the mass body ( 260), viewed in cross section, is provided with a thickened portion (264) on its free end remote from the extension (72). 5. The wiper blade of claim 1, wherein the support element (42) in an unstressed state, is curved in the longitudinal direction; that a connection device (44) for a wiper arm (48 ) is located on the convex outer side (43) of the support element (42); and that the wiper strip (46) is disposed on the concave inner side (49) of the support element (42). 6. A wiper blade for cleaning windows of motor vehicles, which transversely to its length is 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 ), wherein 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 freely movably, and in particular tiltably, relative to the wiper strip and support element at least in the displacement direction (74) of the w per blade, to suppress chattering motion of the wiper blade wherein the wiper strip has a base body (64), which on a side remote from the window (54) changes over via an extension (68) to the mass body (60, 160, 260, 360, or 460, respectively); and that a striplike wiper lip ( 56) that can be placed against the window and that is made jointly with the base body from a different material than the mass body and is joined thereto via a rib strip which is disposed on the side of the base body (64) toward the window (54). 7. The wiper blade of claim 6, wherein a spoiler (500 or 260 or 600 or 700) embodied as an elongated hollow body is formed onto the extension (68), and located in the cavity of the spoiler is the mass body (560 or 760) that is joined to the extension and is movable in the displacement direction ( 74) of the wiper blade. 8. The wiper blade of claim 6, wherein 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 mass body 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.
