Problems solved by technology

[0003] A disadvantage of the prior art is that the connection between the wiper arm and the wiper blade is realized by means of an articulation comprising a combination of a base connection and an adapter unit, which has a relatively large structural height and thus provide a correspondingly large active surface
For example, when using wiper blades for windshield wipers, this can lead to undesired wind noise due to the corresponding oncoming wind.

Embodiment approach

[0032] According to one specific embodiment, the wiper blade 100 is designed as a flat rod, ie the wiper strip 112 has lateral longitudinal grooves, which are formed, for example, on the back strip 124 and in which two support rails, Spring rails are preferred. As an alternative thereto, the wiper strip 112 can be designed as a hollow profile with an approximately central longitudinal channel, for example provided in the back strip 124 , in which a separate support rail is arranged.

[0033] Attached to the wiper strip 112 is an adapter unit 160 , which is covered by an optional cover-like fastening element 150 and serves to articulate the wiper strip 112 to a wiper arm 190 with which the wiper arm can be guided. The water blade 100 is intended to wipe over a window pane 122 indicated by a dotted line, for example a motor vehicle window pane. The adapter unit 160 is preferably fastened permanently to the wiper strip 112 , for example at least partially in an interruption or r...

Abstract

In the case of a wiper blade for a window wiper, with a wiper strip (112) and an adapter unit (160) for coupling the wiper strip (112) to a wiper arm (190), the adapter unit (160) is fastened permanently to the wiper strip (112) and has a wall element (261) which faces the wiper strip (112) and on which at least one bolt-like fixing element (355) is provided, said fixing element being designed to engage in at least one recess (390), which is provided on the wiper arm (190), in order to fix the wiper arm (190) to the adapter unit (160).

Description

technical field [0001] The invention relates to a wiper blade for a windshield wiper, which has a wiper strip and an adapter unit for articulated connection of the wiper strip to a wiper arm. Background technique [0002] WO 2008 / 145481 A1 describes such a wiper blade with a wiper strip which is articulated to the wiper arm via an associated adapter unit. For this purpose, the adapter unit is fastened to a base connection which is fastened to the wiper strip. [0003] A disadvantage of the prior art is that the connection between the wiper arm and the wiper blade is realized by means of an articulation comprising a combination of a base connection and an adapter unit, which has a relatively large structural height and thus provide a correspondingly large active surface. For example, when using wiper blades for windshield wipers, this can lead to undesired wind noise due to the corresponding oncoming wind. Contents of the invention [0004] It is therefore the object of ...
