1. A wiper blade (10) for an automobile windshield (14), with an elongated belt-shaped, flexible resilient support element (12) having a longitudinal axis, 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 a 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, wherein between the two sides (48, 50 or 136, 138) of the wind deflection strip (42 or 112) there is at least one support means (58 or 144) located at a distance from their common base point (46 or 134) that stabilizes the sides, wherein the support means is made up of a wall (58 or 144) connected to both sides (48, 50 or 136, 138) that extends in the longitudinal direction of the wind deflection strip (42 or 112), and wherein the wall (58 or 144) extends along the entire length of the wind deflection strip (42 or 112).
