AUTOMOBILE WINDSHIELD WIPER BLADE
First Claim
1. A wiper blade (10) for an automobile windshield (14), with an elongated belt-shaped, flexible resilient support element (12), on the lower belt surface (22) of which that faces the windshield is located an elastic rubber wiper strip 24 sitting against the windshield that extends parallel to the longitudinal axis, and on the upper belt surface (16) of which a wind deflection strip (42 or 112) is located that has an incident surface (54 or 140) facing the main flow direction of the driving wind (arrow 52), said deflection strip extending in the longitudinal direction of the support element, characterized in that the wind deflection strip has two sides (48, 50 or 136, 138) that diverge from a common base point (46 or 134) as seen in a cross section, that the incident surface (54 or 140) is located at the exterior of one side (50 or 138) and that the profile of the cross section of the wind deflection strip is the same along its entire length, wherein the support element has outer edges, and wherein the sides of the wind deflection strip have respective free ends having thereon respective claw-like extensions that fittingly grip around the outer edges of the support element at least in sections, so that the wind deflection strip can be snapped onto the outer edges or slid onto the outer edges in a longitudinal direction.

Abstract
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, (arrow 52), 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.
