Abstract:
1. A wiper blade ( 10 ) to clean windshields ( 20 ), provided with an elongated belt-shaped, flexible spring support element ( 12 ) having top and bottom belt surfaces, with a separate first component designed as an elastic rubber wiper strip ( 14 ) that can be pressed against the windshield ( 20 ) located at the bottom belt surface ( 13 ) of the support element and with a separate second component located at the top belt surface ( 11 ) of the support element ( 12 ) that is designed as a wind deflection strip ( 24 ) that extends at least along a longitudinal section of the wiper blade ( 10 ), characterized in that the two components ( 14 , 24 ) are connected together at their sides facing one another, wherein the support element ( 12 ) has two flexible rails ( 28 ) at a distance from one another, characterized in that the two components ( 14 , 24 ) are connected together through a longitudinal slot ( 32 ) remaining between the flexible rails, and characterized in that to connect the wiper strip ( 14 ) to the wind deflection strip ( 24 ), a separate third bar-shaped component ( 70 ) is provided that has a longitudinal notch ( 72 ) at each of two of its longitudinal sides opposite one another, said notches lying in the same plane, to hold the inner strip edges ( 30 ) of the flexible rails ( 28 ) that face one another, and that between these notches is a stem ( 74 ) whose width is determined by the width ( 34 ) of the longitudinal slot ( 32 ) and with the width of the longitudinal notches ( 72 ) being determined by the thickness of the flexible rails ( 28 ), and with the two other longitudinal sides of the bar-shaped component ( 70 ) forming positive profile shapes that mate with negative profile shapes in the wiper strip ( 14 ) as well as in the wind deflection strip ( 24 ).
