Problems solved by technology

[0007] In addition, the conversion of the teachings of the known prior art has proven to be difficult, since the parameters used cannot be directly used for newly manufactured wiper blades.

Embodiment Construction

[0027] The wiper blade 10 shown in FIG. 1 has an elongated elastic carrier element 12 , also referred to as a flat beam, for the wiper blade 14 , which is shown separately in FIG. 10 . As can be seen from FIGS. 1 , 3 and 4 , the carrier element 12 and the wiper blade 14 are connected to one another with their longitudinal axes parallel. On the top of the carrier element 12 facing away from the glass 15 to be wiped (shown with dotted lines in FIG. 1 ), a connecting device 16 as a connecting mechanism is installed, by means of which the wiper blade 10 can be connected to the automobile. The driven wiper arm 18 of the body is detachably connected. An elongated, rubber-elastic wiper strip 14 is mounted on the underside of the carrier element 12 facing the glass 15 .

[0028] A hook is formed on the free end 20 of the wiper arm 18 as a counter-connection device, which hook can hold a hinge pin 22 belonging to the connection device 16 of the wiper blade 10 . The detachment protect...

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).

Description

technical field [0001] The invention relates to a wiper blade for glass, in particular to a windshield of an automobile, and a method for its manufacture. Background technique [0002] In such wiper blades of the stated type, the carrier element should ensure the pressing force of the wiper blade from the wiper arm on the glass over the entire wiping range swept by the wiper blade—often also referred to as the contact force. Combined pressure—distributed in a predetermined manner. Due to the appropriate curvature of the unloaded load-bearing element (exactly when the wiper blade is not in contact with the glass), the end of the wiper blade, which is completely in contact with the glass during the operation of the wiper blade, passes through and is tensioned The load-carrying element exerts a load against the glass, even though the radius of curvature of the spherically curved vehicle glass varies in each wiper blade position. To be precise, the curvature of the wiper blade...
