Abstract
A wiper blade (,) is proposed that serves to clean windows of motor vehicles. The wiper blade has an elongated, rubber-elastic wiper strip (,) which can be placed against the window to be wiped and is disposed substantially longitudinally axially parallel to one face, that is, the face oriented toward the window, of a striplike, spring-elastic support element (,), which is connected to a wiper arm (,) that is driven crosswise to the length of the wiper blade and can be urged toward the window. Even at high vehicle speeds, a requisite wiper blade contact pressure for attaining a swept field clean enough to meet legal requirements is achieved if the wiper blade (,) is provided with a leading-edge face (,or,), which extends longitudinally of the wiper blade and substantially parallel to the window and faces into the wind (arrow,), and which crosswise to its length forms an acute angle with the window.
