Problems solved by technology

[0004] The disadvantage of the above-mentioned solution is manifested in the following situation: when the snap-in element breaks, the wiper blade is no longer reliably held on the wiper arm
In addition, the snap-in elements have to be manipulated in order to replace the wiper blade, so the removal of the wiper blade is relatively complicated

Embodiment Construction

[0036] figure 1 The assembly of a wiper arm 12 and a wiper blade 14 of a connection mechanism 10 of a vehicle wiper system is shown in perspective. A coupling element in the form of an adapter 16 serves to fasten the wiper blade 14 on the wiper arm 12 .

[0037] The adapter 16 comprises an upper part 18 with a U-shaped cross-section and a lower part in the form of a slider 20 holding a body 22 of the wiper blade 14 . In this case, the body 22 comprises a spring rail 24 and a wiper lip 26 of the wiper blade 14 . The upper part 18 of the adapter 16 includes a back 28 and lateral sides 30 connected to the back 28 . A (not shown) metal pin is held on the side edge 30 of the upper part 18, and on the upper part 18 fixed on the slider 20 (see Figure 5 ), the metal pin runs through a through-hole 32 formed in the sheet-like region of the slider 20 . By means of the metal pin supported in the through-hole 32, an axis of rotation 34 is provided.

[0038] In this way, the sliding ...

Abstract

The invention relates to a wiper blade (14) for a windscreen wiper system of a vehicle, comprising an attachment element (16) which comprises an upper piece (18) designed to secure the attachment element (16) to a wiper arm (12) of the windscreen wiper system. A lower piece (20), which holds a base of the wiper blade (14), is rotatably mounted on the upper piece (18) about an axis of rotation. The attachment element (16) can be moved into a function position which allows the windscreen to be wiped and in which at least one latching element (52) located on the upper piece (18) is latched to a counter piece (44) provided on the sides of the wiper arm (12). The at least one latching element (52) can be moved into a release position by displacing the lower piece (20) relative to the upper piece (18), in which release position the attachment element (16) can be detached from the wiper arm (12). The invention further relates to a wiper arm (12) and to a connection arrangement (10) for a windscreen wiper system.

Description

technical field [0001] The invention relates to a wiper blade for a wiper device of a vehicle, comprising an engagement element. The upper part of the coupling element is used to fasten the coupling element to a wiper arm of the wiper device. A lower member is rotatably supported on the upper member, and the lower member holds the main body of the wiper blade. The engaging element can be brought into an operating position allowing wiping of the glass, in which at least one engaging element arranged on the upper part and at least one engaging element arranged on the side of the wiper arm The mating parts are snapped together. In addition, the present invention also relates to a wiper arm for a vehicle wiper device, on which the wiper blade can be fixed, and a connection mechanism comprising the wiper blade and the wiper arm. Background technique [0002] DE 10 2008 011 449 A1 describes a solution for connecting a wiper blade to a wiper arm with a wiper blade-side adapter w...
