ABSTRACT:
The invention relates to a wiper blade that cleans panes, in particular of motor vehicles. The wiper blade (10) comprises a strip-shaped, elongated, elastically resilient support element (12), the lower strip surface of which faces the pane (14) and is provided with an elongated, elastic wiper strip (24) running parallel to the longitudinal axis. The upper strip surface (16) of the element is provided with a wind deflector strip (42), which consists of an elastic material, extends in the longitudinal direction of the support element and has an oncoming stream surface (54) that faces the principal flow direction, (arrow52), of the air stream. A particularly advantageous wiper blade, which is cost-effective to produce, can be achieved if the wind deflector strip, (when viewed in cross-section), comprises two limbs (48, 50), diverging from a common base (46) but mutually attached thereto, the free ends of said limbs facing the pane (14) and being supported on the wiper blade and if in addition, the oncoming stream surface (54) is configured on the external face of one limb (50) and the cross-sectional profile of the wind deflector strip is the same over its entire length.
