Embodiment Construction

[0024] figure 1 Shown is a wiper blade 10 with a wiper strip 12 having a wiper lip 29 connected to a rear strip 24 via a pivot web 27 . An adapter unit 50 for connecting to the wiper arm 18 is fixed on the wiper strip 12 . With the aid of the wiper arm 18 , the wiper blade 10 for wiping can be guided through a glass 22 shown in dotted lines, such as a motor vehicle windshield.

[0025] According to one specific embodiment, the wiper blade 10 is designed as a jointless wiper blade, that is to say the wiper strip 12 and the wiper arm 18 are connected to one another via an adapter unit 50 without a substantially formed pivot axis. , so that the wiper arm 18 and the wiper strip 12 cannot pivot relative to each other. This type of connection is also referred to below as a "jointless connection" or "jointless fixation". Components that enable a relative movement between wiper arm 18 and wiper strip 12 due to material deformation, in particular elastic deformation, are not conside...

Abstract

The present invention relates to a wiper blade which is provided with a transferring unit used for fixing on a wiper arm, wherein the wiper blade is used for a wiper and is provided with wiper strips and the transferring unit used for fixing the wiper strips on the wiper arm. For the wiper blade, the wiper strips are provided with back strips, and the transferring unit is provided with at least two foldable transferring pieces; the transferring pieces are provided with head regions which are mutually connected through a joint and attached foot regions, wherein the transferring pieces form a fixed element in a foldable state. The fixed element fixes the wiper arm in the transferring unit along an axial direction of the wiper blade, wherein the foot regions of the transferring piece at least partially clamp the back strips of the wiper strips and fix the back strips in a preset position in the transferring unit relative to the wiper arm.

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 fastening the wiper strip to a wiper arm. Background technique [0002] EP 0 141 186 B1 describes a wiper blade for which an adapter unit consisting of a plastic injection-molded body with a shaped joint has two approximately symmetrical blades that can be pivoted about the joint. part. These parts are arranged at the end of the wiper arm and are fastened to each other and thus at the end of the wiper arm by being folded together. The folded parts form a circular-arc-shaped support element into which a cylindrical pivot shaft arranged on a wiper strip assigned to a wiper blade can be inserted. [0003] A disadvantage of this prior art is that a pivot shaft arranged on the wiper strip is required to be able to fasten the adapter unit fastened to the wiper arm to the wiper strip. The adapter unit must first also be attached to the wiper arm b...
