Wiper blade for windows of motor vehicles
First Claim
1. A wiper blade for windows of motor vehicles, comprising an elongated, strip-shaped, spring-elastic, curved support element having two legs which have a longitudinal extension following a curvature, convex upper sides defining a plane which follows the curvature, and concave lower sides;
- an elongated, rubber-elastic wiper strip located substantially longitudinally axially parallel directly on said concave lower sides of said legs;
a connection device provided for connection of the wiper blade with a wiper arm and arranged directly on said convex upper side of said legs; and
a leading-edge face formed on a projection being of unitary construction with the wiper strip, which is arranged on said convex upper sides of said legs and which encloses en acute angle with a plane defined by said convex upper aides of said legs of said support element so as to generate a force component which counters a liftoff tendency of the wiper blade and keeps a contact pressure of the wiper blade on a vehicle window, wherein the wiper strip has a base body, wherein a wiper lip is formed on the base body by means of a tilting rib and wherein two, opposed side longitudinal grooves that are open at their periphery are provided in the base body, wherein the legs of the support element are introduced into the longitudinal grooves and wherein a narrow connecting rib remains between the two opposed longitudinal grooves, wherein said projection is composed of a material which is different and softer than that of said sweeper strip.

Abstract
A wiper blade for wiping windows of motor vehicles has an elongated rubber-elastic wiper strip placeable on a window to be wiped and arranged substantially longitudinally axially parallel on a surface of a strip-shaped, spring-elastic support element which is connected with a wiper arm which is spring loaded toward the window and driven transversely to a longitudinal extension of the wiper blade, and a leading-edge face extending longitudinally of the wiper blade and substantially parallel to the window and facing into a wind so as to form an acute angle with the window.
