Problems solved by technology

The windscreen wiper devices of the prior art are designed as so-called "flat blades" or "yokeless blades", in which the various yokes (yokes) which are pivotally connected to each other are not used, but in which the wiper blade is carried by the element bias, the result is a specific bending

Embodiment Construction

[0015] figure 1 A preferred variant of a flat-blade windscreen wiper device 1 according to the invention is shown. The windscreen wiper device 1 is provided with an elastic wiper blade 2 comprising a central or central longitudinal groove 3, wherein a central or central longitudinal strip 4 made of spring strip steel is in contact with the longitudinal groove 3 with (see Figure 2 to Figure 5 ). The strip 4 forms, as it were, a flexible bearing element for the rubber wiper blade 2 , so that the strip 4 is biased in a bent position (the curvature of the operating position being the curvature of the windshield to be wiped). One end of the strip 4 and / or one end of the wiper blade 2 can be connected to respective webs or “end caps” 5 on either side of the windscreen wiper device 1 . In this embodiment, the web 5 is a separate constructional element which can be form-locked and force-locked to both ends of the strip 4 / the wiper blade 2 . In another preferred variant, the conn...

Abstract

A windscreen wiper device (1) of the flat blade type comprising an elastic, elongated carrier element, as well as an extruded elongated wiper blade (2) of a flexible material, which wiper blade (2) includes a central longitudinal groove (3), in which groove (3) a longitudinal strip (4) of the carrier element is disposed, with the special feature that said groove (3) extends in downward direction beneath the longitudinal strip (4) for forming a longitudinal hollow channel (18) defined by said longitudinal strip (4) and a bottom (19) of said groove, wherein a height of said hollow channel (18) at the location of a middle longitudinal plane of said wiper blade (2) perpendicular to the windscreen to be wiped is defined by: 1 / 40 W <= H <= 1 / 5 W, wherein W is a width of the longitudinal strip, and wherein H is a height of the hollow channel at the location of a middle longitudinal plane of said wiper blade perpendicular to the windscreen to be wiped.

Description

technical field [0001] The present invention relates to a windshield wiper device of the flat blade type comprising an elastic elongated carrier element and an extruded elongated wiper blade made of a flexible material, the wiper blade comprising A wiping element capable of being placed adjacent to a windshield to be wiped, the wiper blade comprising a central longitudinal groove in which a longitudinal strip of the carrier element is arranged, the windshield wiper device comprising a connection for an oscillating arm device, wherein the swing arm is pivotally connected to the connecting device about a pivot axis near one end of the swing arm. Background technique [0002] Such windscreen wiper arrangements are generally known. The windscreen wiper devices of the prior art are designed as so-called "flat blades" or "yokeless blades", in which the various yokes (yokes) which are pivotally connected to each other are not used, but in which the wiper blade is carried by the el...
