Embodiment Construction

[0029] A wiper blade 10 comprises a central bracket 12, at its two ends are hinged clamping brackets 14 arranged below, the clamping bracket 14 has a clamping head 16 for accommodating a wiper strip 18 (FIG. 1 ). The wiper strip 18 extends elongately and is gripped at several points in a clamping region by the clips 16 .

[0030] FIG. 2 shows an enlarged sectional view through the clamping head 16 . The clip 16 holds the gripping region of the wiper strip 18 , the so-called profiled back 20 , which preferably has an overall width of 6 to 10 mm and an overall height of 3.5 to 7 mm. Furthermore, the profiled back 20 is reinforced by two spring struts 24 as reinforcement elements. If only one spring bar 24 is used, it is usually placed in the middle. According to different vehicle models, the thickness of the spring pressing bar 24 can be changed between 0.7 and 1.2 mm, and the width can be between 2.5 and 4.5 mm.

[0031] The profiled back 20 is connected via a first pivot b...

Abstract

The invention relates to a wiper strip (18) for windscreen wipers, comprising a shaped back section (20) and a functional part (22) which is connected to said shaped back section (20) by a tilting link (26) and which is supported on the shaped back section in the tilted position. According to the invention, the functional part (22) comprises a support section (13) which is connected to the shaped back section (20) by a first tilting link (26) and to a wiper wedge (32) by a second tilting link (28).

Description

technical field [0001] The invention relates to a wiper strip for a windscreen wiper. Background technique [0002] The known windshield wiper has a wiper arm consisting of a fastening part and an articulation part with the wiper lever, which is articulated thereon via a pivot joint. As a rule, a hook-shaped end of the wiper rod engages in a suspension box of a wiper blade formed by two lateral stem arms of a central bow and embraces a hinge pin. The hinge formed in this way guides the movement of the wiper blade over the windshield of the motor vehicle during the pivoting movement. [0003] The wiper blade consists of a multi-element support bracket system with associated brackets articulated on a central bracket, at least some of which hold the wiper strip at their ends by means of clips . The longitudinally extending wiper strip is made of rubber and has a profile with two main parts: a profiled back and a functional part. The wiper strip is connected to the support b...
