WIPER BLADE FOR CLEANING MOTOR VEHICLE WINDOWS
First Claim
1. A wiper blade for cleaning windows of motor vehicles, having a band-like, elongated, spring-elastic carrying element (30) whose one band surface oriented away from the window (24) has a device (32) for the connection of an oscillatingly driven wiper arm (34) disposed on it and whose band surface oriented toward the window has an elongated, rubber-elastic wiper strip (17) disposed on it that can be placed against the window and is disposed so that its longitudinal axis is parallel to the carrying element, and the wiper arm moves the wiper blade lateral to its longitudinal span during the wiping operation, wherein the carrying element moves in a plane essentially parallel to the window surface, characterized in that in each of the two oscillating directions (12, 26) viewed perpendicular to the window surface, a straight line (38) extending through the longitudinal center of the two ends of the wiper blade is disposed behind the center (40) of the connecting point between the wiper arm (34) and the wiper blade (10) in the respective wiping direction.

Abstract
A wiper blade is proposed, which is used for cleaning windows of motor vehicles. The wiper blade has a band-like, elongated, spring-elastic carrying element (30) whose one band surface oriented away from the window (24) has a device (32) for the connection of an oscillatingly driven wiper arm (34) disposed on it and whose other band surface oriented toward the window has an elongated, rubber-elastic wiper strip (17) disposed on it that can be placed against the window (24) and is disposed so that its longitudinal axis is parallel to the carrying element, and the wiper arm moves the wiper blade lateral to its longitudinal span during the wiping operation, wherein the carrying element moves in a plane essentially parallel to the window surface. A reliable and low-noise tilting over of the wiper lip belonging to the wiper strip from its one drag position into the other is achieved when in each of the two oscillating directions (12, 26) viewed perpendicular to the window surface, a straight line (38) extending through the longitudinal center of the two ends of the wiper blade is disposed behind the center (40) of the connecting point between the wiper arm (34) and the wiper blade (10) in the respective wiping direction.
