Title:
自動車の板ガラス用のワイパブレード並びに該ワイパブレードの製法
Document Type and Number:
Japanese Patent JP4658422
Kind Code:
B2
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 * L<2> / 48 * E * Izz < 0.009 when Fwf is 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 Izz is 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).
