Problems solved by technology

[0004] The friction coefficient of the protective rail fastened to the protective slat is relatively high, which can cause the protective rail to rotate out of the wiper blade to be protected during dry running, or the wiper motor can no longer apply a higher torque, and cause Stopping the wiper system

Embodiment Construction

[0018] figure 1 The principle configuration of the first embodiment of the invention is shown. The wiper blade 10 has a wiper strip 14 which has a wiper rubber lip 16 which is connected to the head strip 20 via a swivel lug 18 . The head strip 20 has two oppositely arranged longitudinal grooves 24 , which form the webs 22 , and into which grooves a flat, beam-like and elastic support element 26 is inserted. The carrier element 26 is prebent in the longitudinal direction in such a way that the wiper blade 10 bears against the window pane with a suitable pressure distribution under the action of the contact force of a wiper arm (not shown).

[0019] The wiper blade 10 also has a wind deflector 12 , which has two inwardly directed longitudinal grooves 28 facing the support element 26 , into which the support element 26 engages and thus secures the wind deflector 12 to the wiper blade 10 . The longitudinal groove 28 of the wind deflector 12 is delimited in the direction of the w...

Abstract

A protective rail is proposed for wiper blades of a windscreen wiper, having a base body (34) for protecting a wiping rubber lip (16) of the wiper blade (10), having attachment elements (58, 90) for releaseably attaching the protective rail (32) to the wiper blade (10) which is to be protected, and having a wiping lip (36) which is formed on the base body (34), wherein the wiping lip (36) is provided with a lubricant, at least in an area of its surface.

Description

technical field [0001] The invention relates to a protective rail for a wiper blade of a windshield wiper according to the preambles of the independent claims, to a method for its production and to its use. Background technique [0002] Especially when delivering a new motor vehicle, it is necessary to protect the wiper strips of the installed wiper blades from soiling or wear. This is achieved in this case by fastening the protective rail to the wiper strip, which in particular protects the wiper lip of the wiper blade from mechanical damage. [0003] From the unpublished patent DE 20 2005 020650 a wiper blade with a protective rail is known, the base body of which has a V-shaped cross-sectional profile and surrounds the wiper lip of the wiper strip, the measure being that the tabs pointing inward engage in the longitudinal recesses of the wiper strip. slot. The side walls of the main body merge in a V-shape at the edge of the protective rail, at which edge the wiper lip ...
