Abstract
A wiper blade is proposed, which is a part of the windshield wiper system of motor vehicles and is used for cleaning windshields of motor vehicles. The wiper blade has an elongated wiping strip, which is held by a support frame and can be moved, stressed in the direction toward the windshield to be wiped, crosswise in respect to its longitudinal extension over the windshield. Viewed in cross section, the wiping strip has an elongated head strip held by the support frame, and an elongated sweeping strip connected with the latter, on whose side facing away from the head strip an elongated wiping lip strip, which rests against the windshield, is fastened via an elongated tilting strip, wherein for distributing the contact load, elongated spring means made of an elastic material are disposed inside the head strip. For stiffening the head strip, the spring means are constituted by at least two rod-like elements, which are arranged in a plane, which is at least approximately parallel with the wiping plane, and at a distance from each other.
