Abstract

A wiper arm arrangement with a wiper arm of a windscreen wiper system of a vehicle and an attachment element having at least one line. The attachment element can be coupled to a connecting element designed for holding a wiper blade and for connecting the wiper blade to the wiper arm. Due to the coupling, at least one corresponding line of the connecting element can be joined onto the at least one line of the attachment element. The connecting element can be fitted onto the attachment element in an installation direction which coincides at least substantially with a direction of longitudinal extent of the wiper arm. The attachment element is arranged on the wiper arm so as to be movable in the direction of longitudinal extent of the wiper arm.

First claim

The invention claimed is:

1. A wiper arm arrangement, comprising:
a wiper blade;
a wiper arm of a windscreen wiper system of a vehicle; and
an attachment element having at least one line, wherein the attachment element is coupled to a connecting element configured to hold the wiper blade and connect the wiper blade to the wiper arm,
wherein, due to the coupling, at least one corresponding line of the connecting element is joined onto the at least one line of the attachment element,
wherein the connecting element is fitted onto the attachment element in an installation direction coinciding with a direction of longitudinal extent of the wiper arm,
wherein the attachment element is arranged on the wiper arm so as to be movable in a forward direction toward a front open end of the wiper arm,
wherein a side wall of the attachment element includes a stop and a projection that protrudes in the forward direction toward the front open end of the wiper arm and wherein when the attachment element moves in the forward direction toward the front open end of the wiper arm, a lower side of the projection runs onto a guide rail which protrudes from a bottom-most portion of a limb of the wiper arm at the front open end of the wiper arm and the stop runs onto the guide rail to ensure that the attachment element cannot move further toward the front open end of the wiper arm.

2. The wiper arm arrangement according to claim 1 , wherein when coupled to the connecting element, the attachment element is moveable in the direction of longitudinal extent through movement of the connecting element.

3. The wiper arm arrangement according to claim 1 , wherein an end region of the wiper arm has at least one latch opening arranged in a back of the wiper arm, in which latch opening a corresponding latch element of the connecting element is received in a functional position of the connecting element.

4. The wiper arm arrangement according to claim 3 , further comprising:
at least one latch element arranged on the attachment element, wherein the at least one latch element is engageable in the at least one latch opening arranged in the end region of the wiper arm by bringing the attachment element into an installation position.

5. The wiper arm arrangement according to claim 4 , wherein when the attachment element is brought into the installation position, the attachment element is taken to the guide rail on the wiper arm before the at least one latch element of the attachment element engages in the corresponding latch opening arranged in the end region of the wiper arm.

6. The wiper arm arrangement according to claim 5 , wherein when the attachment element is fixed on the wiper arm in the installation position, the connecting element is detachable from the attachment element by further movement of the connecting element in the forward direction toward the front open end of the wiper arm.

7. The wiper arm arrangement according to claim 1 , wherein the at least one line of the attachment element is configured to carry washer fluid or heat into the connecting element.

8. The wiper arm arrangement according to claim 1 , wherein the wiper arm arrangement comprises the connecting element having at least one latch element comprising a recess open in the installation direction, in which a journal arranged on the attachment element is received in a latched manner when coupled with the attachment element.

9. The wiper arm arrangement according to claim 1 , wherein the wiper arm arrangement has the connecting element comprising an upper part arranged on the wiper arm, on which upper part a lower part of the connecting element configured to hold the wiper blade and having insertion element is supported such that it can rotate about a rotational axle.
