Embodiment Construction

[0049] FIG. 1 shows a device 10 according to the invention for the detachable connection of a wiper blade 12 , shown in part, to a drivable wiper arm 14 , also shown in part. The wiper blade 12 has a wiper strip 16 facing the unillustrated glass to be wiped; this wiper strip comprises two strip-shaped elongated support elements 18, 20, an outer wrapping element 22 connected to the support elements 18, 20 and a connecting element 24 which is swingably arranged on the outer covering element 22 . The connecting element 24 is used for connecting to a connecting section 26 on the wiper arm 14 .

[0050] especially if Figure 4 It can be seen that the connecting section 26 has a tongue-shaped insertion section 28, a receiving groove 30 can be seen clearly in FIG. in the slot. The connecting element 24 , like the joining section 26 , is also U-shaped in cross-section and has a top 32 and two sides 34 . The receiving groove 30 is arranged on the top 32 of the connecting element 24...

Abstract

The invention relates to a device and a method for detachably linking a wiper blade (12) with a driven wiper arm (14), whereby said wiper blade (12) comprises a wiper strip (16) facing the pane to be wiped, at least one strip-like oblong support element (18, 20), a bridle element (22) linked with said support element (18, 20), and a joining element (24), oscillatingly mounted on the bridle element (22), for connection to a coupling section (26) of the wiper arm (14). The invention is characterized in that the coupling section (26) comprises a tongue-shaped insertion section (28), in that the joining element (24) comprises a seat for the insertion section (28) and in that the coupling section (26) and the joining element (24) comprise securing sections (42, 56) for durably interlinking them. In order to achieve a preassembly position in which the longitudinal axis of the wiper arm (14) forms an angle beta in the range of approximately 10 DEG to 100 DEG with the longitudinal axis of the joining element (24), the insertion section (28) can be inserted in the seat (30) in a substantially linear direction (64). In order to achieve a post-assembly position, the wiper arm (14) and the linking section (24) can be pivoted relative each other about the contact area of insertion section/seat until the securing sections (40, 42, 56) allow a permanent interlinkage.

Description

technical field [0001] The invention relates to a device and a method for detachably connecting a wiper blade to a drivable wiper arm, wherein the wiper blade comprises a wiper strip facing a glass to be wiped, at least one strip-shaped elongated support element , an outer covering element connected to the support element and a connecting element pivotably supported on the outer covering element for connection to a coupling section of the wiper arm. Background technique [0002] A device of this type is known, for example, from WO 02 / 40328 A1. A flat wiper blade can be connected to the joining section by means of this device, which comprises a series of structural parts which are complex and expensive to manufacture. In addition, the connecting process of the connecting section of the wiper arm to the connecting element of the wiper blade is relatively complicated and requires a certain skill. Contents of the invention [0003] It is therefore the object of the present i...
