Abstract

The invention relates to a wiper device (100) for the cleaning of vehicle windows (1), with a wiper blade (10) having a wiper rubber (12), which wiper blade is able to be fastened exchangeably on a wiper arm (2) by means of a wiper blade adapter (11), wherein between the wiper blade adapter (11) and the wiper arm (2) a detent connection (15) is constructed, which comprises a detent element which is arranged on the wiper blade adapter (11) and which engages in a form-fitting manner into a corresponding opening (16) or recess on the wiper arm (2). According to the invention, the wiper blade (10) has an ageing indicator element (21) for the wiper blade (10), said ageing element being covered by a protective element (25), wherein the protective element (25) is constructed such that, and/or is arranged on the wiper blade (10) such that a mounting of the wiper blade (10) on the wiper arm (2) is only possible after a removal of the protective element (25) from the ageing indicator element (21).

Claims

1. A wiper device for the cleaning of vehicle windows, comprising:

a wiper blade having a wiper rubber, wherein the wiper blade is fastened exchangeably on a wiper arm by a wiper blade adapter,

wherein between the wiper blade adapter and the wiper arm a detent connection is constructed, which comprises a detent element which is arranged on the wiper blade adapter and which engages in a form-fitting manner into a corresponding opening or recess on the wiper arm,

wherein the wiper blade has an ageing indicator element for the wiper blade, said ageing element being covered by a protective element, wherein the protective element is constructed or arranged on the wiper blade such that a mounting of the wiper blade on the wiper arm is only possible after a removal of the protective element from the ageing indicator element.

2. The wiper device according to claim 1, wherein the detent element is constructed on the wiper blade on the upper side of the wiper blade adapter in the form of a securing tongue with an actuating button, wherein the actuating button is arranged so as to be visible from the exterior when the wiper blade is mounted on the wiper arm, and wherein the ageing indicator element is arranged in the region of the upper side of the actuating button.

3. The wiper device according to claim 2, wherein the ageing indicator element is constructed in a plate shape and is held in a form-fitting manner in a depression which is constructed on the upper side of the actuating button.

4. The wiper device according to claim 2, wherein the protective element is detachably connected with the ageing indicator element and has a greater area than the opening or recess on the wiper arm.

5. The wiper device according to claim 4, wherein the protective element consists of plastic.

6. The wiper device according to claim 1, wherein the protective element does not project over the wiper blade adapter in its width.

7. The wiper device according to claim 1, wherein the protective element is marked with an inscription.

8. The wiper device according to claim 7, wherein the ageing indicator element in its new state has a color which is matched to the color of the wiper arm, and wherein on ageing of the ageing indicator element, the latter has a color change, which forms a contrast to the color of the wiper arm.

9. The wiper device according to claim 8, wherein through the color change, an indication for exchanging the wiper blade, in a form of a further inscription, is visible.

10. A wiper blade for use in a wiper device according to claim 1.
