Embodiment Construction

[0035] figure 1 The wiper blade 10 shown in has a strip-shaped longitudinally extending one-piece or multi-piece (one-piece or separate) elastic support element 12 whose strip surface is bent in the longitudinal direction in the unloaded state. On the belt surface or the belt side 16 on the upper or outer side of the arched support element away from the wiper glass 14 side ( figure 1 and image 3 ), wherein a connecting device 18, for example planarly abutting against it, is installed in its middle part, by means of which the wiper blade 10 can be detachably connected to the motor-driven wiper blade swing arm 20 leading to the vehicle body connect. On the strip surface or strip side 22 of the curved support element 12 directed towards the concave lower part or inside of the glass, a longitudinally extending elastic rubber wiper strip 24 is mounted, which extends parallel to the longitudinal axis to the support element 12( image 3 ). At the free end of the wiper swing arm...

Abstract

A wiper blade is proposed, which is used to clean windows, in particular of motor vehicles. The wiper blade is arranged with a rubber elastic wiper strip (24) on the one band surface (22) of a band-like, long-stretched-out, elastic supporting element (12) and can be placed on the to-be-wiped window (14). The other band surface (16) of the supporting element is covered by another component (40) of the wiper blade (10), at least in sections, and this covering part is provided with claw-like projections (54) arranged in the longitudinal direction of the wiper blade, which grip under holding edges (38) of the supporting element. A particularly tension-neutral and easily mountable wiper blade is achieved if the covering part (40), manufactured of an elastic plastic, is provided with an armoring (60) in the area of its projections (54) whose strength is greater than the strength of the plastic used for the covering part.

Description

Background technique [0001] For wiper blades with spring-band support elements, it is to be ensured that the pressure of the wiper arm on the wiper blade is distributed as evenly as possible on the glass over the entire wiper area wiped by the wiper blade. Since the supporting element is in a correspondingly curved state in the unloaded state, i.e. the wiper blade rests on the glass only at the two ends, the tension of the spherical vehicle glass changes even if the radius of curvature of the spherical vehicle glass is changed in any position of the wiper blade. A tight support element also causes the wiper blade to press against the glass when it moves completely through the end of the wiper strip on the glass. Since the wiper strip, i.e. the wiper edge of the wiper strip against the glass, must always be pressed against the glass with a certain pressure during wiping, compared to the point of greatest curvature on the glass to be wiped in the wiping area , the curvature of ...
