Abstract

A wiper blade is proposed, which is used for cleaning windows, particularly of motor vehicles. The wiper blade (10) has an elongated, rubber-elastic wiper strip (14), which can be placed against the window (22) and is connected in a longitudinally parallel fashion to an elongated, spring-elastic support element (12), which has a connecting device (16) for a wiper arm (18). The wiper blade has two band-like spring strips (28, 30), which are parallel to each other and are disposed in a plane spaced a distance (26) apart from the window (22) and whose one, inner longitudinal edges (32) disposed close to each other are spaced a distance (34) apart from each other, and the wiper strip, which has a uniform cross section over its longitudinal span, has a strip-like wiper lip (102), which can be placed against the window and which, by means of a narrow intermediary strip (102) that is formed by opposing groove-like constrictions (106), is connected to a covering strip (104) secured to the support element (12), and the spring strips secure the wiper strip. A wiper blade, which is particularly low-profile and therefore insensitive to the flow conditions of the window, is obtained if each of …
