Abstract

A wiper blade (10) is proposed that serves to clean windows of motor vehicles. The wiper blade has an elongated, rubber-elastic wiper strip (14) which is provided on its two long sides with respective facing longitudinal grooves (38, 40), in each of which one spring rail (30, 32), protruding intermittently from the grooves by one longitudinal edge (42, 44), is disposed; the spring rails belong to an elongated, spring-elastic support element (12) for the wiper strip (14), on whose middle portion a connection device (16) for a wiper arm (18) guided on the vehicle body is disposed. An especially simple disposition of a wind deflector strip and a connection device for a wiper arm are obtained if at least one longitudinal portion of the part of the wiper strip located on the side of the spring rails (30, 32) remote from the window is embodied as a wind deflector strip (54), and if furthermore the connection device (16) is retained on the longitudinal edges (42, 44) of the spring rails (30, 32) that protrude from the longitudinal grooves (38, 40).
