ABSTRACT:
The invention relates to a wiper blade for windshields, especially automobile windshields, comprising at least one support element, a support element (12), a wiper strip (14) and connecting means (16) for a wiper arm (18). The support element (12) is a long flat rod to which the wiper strip (14) and the connecting means (16) are fixed. According to the invention, the flat rod has a cross-sectional profile (40), whereby Fwf*L2/48*E*Izz<0.009 when Fwfis the pressure force exerted on the wiper blade or the pressure force for which the wiper blade was originally intended, L represents the length of the wiper blade, E stands for the elasticity module of the flat rod material and Izzis the moment of inertia of the cross-sectional profile around the z axis (perpendicular to an s axis associated with the flat rod and perpendicular to the y axis).
