Claim:
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.
