Abstract

A wiper blade arrangement having an attachment element that holds a wiper blade, which can be secured on a wiper arm of a windscreen wiper system of a vehicle. The wiper blade is coupleable via the attachment element to at least one channel for washer fluid, which can be introduced from the wiper arm into the attachment element. The attachment element allows a relative movement of the wiper blade with respect to the wiper arm. For this, the attachment element has a rider designed for holding a spring strip of the wiper blade, which includes a wiper-arm-side upper part and a wiper-blade-side lower part, which are connected to each other via a central part of the rider, which encloses at least one line for the washer fluid, wherein the central part has greater elasticity than the upper part and the lower part of the rider.

First claim

The invention claimed is:

1. A wiper blade arrangement, comprising:
a wiper blade;
a wiper arm of a windscreen wiper system of a vehicle; and
an attachment element configured to secure the wiper blade to the wiper arm,
wherein the wiper blade is coupled to at least one washer fluid channel for washer fluid via the attachment element,
wherein washer fluid is introduced into the attachment element from the wiper arm,
wherein the attachment element provides a relative movement of the wiper blade with respect to the wiper arm,
wherein the attachment element includes a detachable plug coupled to the at least one washer fluid channel for washer fluid via a respective connecting piece and a rider configured to hold a spring strip of the wiper blade,
wherein the detachable plug has at least one line section piece arranged perpendicularly downward relative to the connecting piece, and
wherein the rider comprises a wiper-arm-side upper part and a wiper-blade-side lower part that are connected to each other via a central part of the rider, wherein the central part has at least one channel piece configured to accommodate the at least one line section piece of the detachable plug when the detachable plug is coupled to the rider so that the central part encloses a flow path of the washer fluid, wherein the central part has greater elasticity than the upper part and lower part of the rider.

2. The wiper blade arrangement according to claim 1 , wherein the attachment element is secured to the wiper arm via a framework element, which is in contact with at least two external sides of the upper part that are opposite each other.

3. The wiper blade arrangement according to claim 2 , wherein the framework element is installed on a rotational axis configured on the lower part.

4. The wiper blade arrangement according to claim 1 , wherein the attachment element is installed onto the wiper arm in an installation direction, which runs at right-angles to a wiping surface defined by a wiping movement of the wiper blade.

5. The wiper blade arrangement according to claim 4 , wherein the attachment element comprises at least one of:
at least one projection protruding above a side wall of the attachment element, which is inserted into a recess on the wiper arm that is open in the installation direction during installation onto the wiper arm; and
at least one guide element arranged on only one side wall of the attachment element, which is guided on a wiper-arm-side guide element having a lead-in chamfer during installation onto the wiper arm.

6. The wiper blade arrangement according to claim 1 , wherein the attachment element has at least one electrical plug connector that is coupled to a wiper-blade-side electrical heat conductor, which is connected to a wiper-arm-side electrical connection during the connection of the attachment element to the wiper arm.

7. A connecting arrangement, comprising:
a wiper blade arrangement, comprising
a wiper blade;
a wiper arm of a windscreen wiper system of a vehicle; and
an attachment element configured to secure the wiper blade to the wiper arm,
wherein the wiper blade is coupled to at least one washer fluid channel for washer fluid via the attachment element,
wherein washer fluid is introduced into the attachment element from the wiper arm,
wherein the attachment element provides a relative movement of the wiper blade with respect to the wiper arm,
wherein the attachment element includes a detachable plug coupled to the at least one washer fluid channel for washer fluid via a respective connecting piece and a rider configured to hold a spring strip of the wiper blade,
wherein the detachable plug has at least one line section piece arranged perpendicularly downward relative to the connecting piece, and
wherein the rider comprises a wiper-arm-side upper part and a wiper-blade-side lower part that are connected to each other via a central part of the rider, wherein the central part has at least one channel piece configured to accommodate the at least one line section piece of the detachable plug when the detachable plug is coupled to the rider so that the central part encloses a flow path of the washer fluid, wherein the central part has greater elasticity than the upper part and lower part of the rider,

a slider arranged on the wiper arm to fixedly hold the attachment element on the wiper arm, wherein the slider is displaceable along the wiper arm from an installation position into a functional position securing the attachment element.

8. The connecting arrangement according to claim 7 , further comprising:
at least one display on the wiper arm, by means of which a passing of the slider into the functional position or the installation position can be displayed to an operator.

9. The connecting arrangement according to claim 7 , wherein the wiper arm has at least one latching notch, which, in the functional position or the installation position of the slider, engages with a latching nose arranged on the slider.

10. The connecting arrangement according to claim 7 , wherein the slider has a back and two limbs, wherein at least one projection that encompasses the wiper arm from below or secures the attachment element in the functional position of the slider is arranged on the limbs of the slider.
