Abstract

The invention relates to a wiper blade for cleaning the windshields of vehicles, comprising at least one elongated carrier element ( 6 ) on which a wiper strip ( 5 ) having at least one wiper lip ( 5.1 ) is held, a wiper blade adapter attached to the carrier element ( 6 ), said adapter being designed to mechanically connect the wiper blade ( 2 ) to a wiper arm ( 1 ) or to a wiper arm adapter ( 11 ) provided on the wiper arm ( 1 ) in a joint direction, at least one electric heating element provided on the wiper blade ( 2 ), and at least one electrical connecting element provided on the wiper blade adapter on the wiper blade side, said connecting element having at least one electrical contact for establishing an electrical connection between the heating element and a power supply provided or held on the wiper arm ( 1 ).

First claim

The invention claimed is:

1. A wiper blade for cleaning windscreens on vehicles, comprising:
at least one elongated carrier element on which at least one wiper rubber presenting a wiping lip is held, wherein the wiper blade is one selected from the group consisting of a flat wiper blade and flat-bar wiper blade;
a wiper blade adapter fixed to the carrier element, designed for detachable mechanical connection of the wiper blade to a wiper arm, wherein a wiper arm adapter is provided on the wiper arm, oriented in a longitudinal extension of the wiper arm in an assembly direction,
wherein the wiper blade adapter consists of at least a first adapter section and a second adapter section, the first and second adapter sections being articulated to each other by an adapter joint, wherein the first adapter section is attached to the carrier element and the second adapter section is configured to connect to the wiper arm and to the wiper arm adapter,
wherein the first adapter section is independent from the carrier element,
wherein the wiper blade adapter comprises at least one electrical connecting element on the wiper blade side provided on the wiper blade adapter, presenting at least one electrical contact for establishment of an electrical connection between a heating element and a current supply provided and held on the wiper arm,
wherein the electrical connecting element on the wiper blade side is designed for detachable connection to an electrical connecting element provided on the wiper arm and on the wiper blade adapter in the same assembly direction as that of the wiper blade adapter, and
wherein the electrical connecting element on the wiper blade side is mounted floating and deflectable in a spatial plane crossways in relation to the assembly direction.

2. The wiper blade according to claim 1 , wherein the wiper blade adapter is equipped with a catch engagement for locking with the wiper arm and the wiper arm adapter.

3. The wiper blade according to claim 1 , wherein the at least one electrical connecting element on the wiper blade side is located on a narrow or front face of the wiper blade adapter and the second adapter section oriented crossways in relation to the assembly direction is accessible for the electrical connection and protrudes over the narrow or front face.

4. The wiper blade according to claim 1 , wherein the at least one electrical contact of the connecting element on the wiper blade side is a contact pin or a contact socket and is oriented with the axis in the assembly direction.

5. The wiper blade according to claim 1 , wherein the at least one electrical connecting element on the wiper blade side presents a housing made of an electrically insulating material with a female connector housing section, the axis of which is oriented in the assembly direction and which is designed to receive a corresponding housing section of a housing section of the electrical connecting element on the wiper arm side, and wherein the at least one electrical contact of the connecting element on the wiper blade side is arranged in the female connector housing section.

6. The wiper blade according to claim 1 , wherein the at least one electrical connecting element on the wiper blade side presents a housing made of an electrically insulating material with a male connector housing section oriented in the assembly direction, which is designed for matching insertion into a female connector housing section of the electrical connecting element on the wiper arm side, and wherein the at least one electrical contact of the connecting element on the wiper blade side is provided on the male connector housing section.

7. The wiper blade according to claim 1 , wherein the electrical heating element is formed of at least one heating foil.

8. The wiper blade according to claim 1 , wherein the second adapter section of the wiper blade adapter is designed to be received with a positive fit in an opening formed by the wiper arm adapter.

9. The wiper blade according to claim 1 , wherein the carrier element continuously contacts the wiper rubber over the length of the wiper rubber.

10. A wiper arm for use with a wiper blade, which is mechanically and detachably connectable to the wiper arm and to a wiper arm adapter by joining in an assembly direction using a wiper blade adapter, the wiper arm comprising:
at least one electrical connecting element on the wiper arm side, which is designed for detachable connection to an electrical connecting element on the wiper blade side provided on the wiper blade adapter in an assembly direction oriented in a longitudinal extension of the wiper arm,
wherein the at least one of these two electrical connecting elements is mounted floating and deflectable in a spatial plane oriented crossways to the assembly direction,
wherein the wiper blade is one selected from the group consisting of a flat wiper blade and flat-bar wiper blade,
wherein the wiper blade adapter consists of at least a first adapter section and a second adapter section, the first and second adapter sections being articulated to each other by an adapter joint, wherein the first adapter section is independent from a carrier element and configured to be attached to the carrier element and the second adapter section is connected to the wiper arm and to the wiper arm adapter, and
wherein the electrical connecting element on the wiper blade side is mounted floating and deflectable in a spatial plane that is crossways in relation to the assembly direction.

11. The wiper arm according to claim 10 , wherein the at least one electrical connect of the connecting element on the wiper arm side is a contact socket or a contact pin and is oriented with the axis in the assembly direction.

12. The wiper arm according to claim 10 , wherein the at least one electrical connecting element on the wiper arm side presents a housing made of an electrically insulating material with a socket-like housing section, the axis of which is oriented in the assembly direction and which is designed to receive a pin-like housing section of a housing of an electrical connecting element on the wiper blade side, and wherein the at least one electrical contact of the connecting element on the wiper arm side is arranged in the socket-like housing section.

13. The wiper arm according claim 10 , wherein the at least one electrical connecting element on the wiper arm side presents a housing made of an electrically insulating material with a pin-like housing section, which is designed for matching insertion into a socket-like housing section of the electrical connecting element on the wiper blade side, and wherein the at least one electrical contact of the connecting element on the wiper arm side is provided on the pin-like housing section, the axis of which is oriented in the assembly direction.

14. The wiper arm according to claim 10 , wherein the wiper arm adapter forms a receiving opening for receiving the wiper blade adapter and a second adapter section with a positive fit, which is open towards a free end of the wiper arm.

15. The wiper arm according to claim 10 , wherein the electrical connecting element on the wiper arm side is held on a retaining plate acting as a leaf spring, which is attached to the wiper arm.

16. The wiper arm according to claim 15 , wherein the electrical connecting element on the wiper arm side is held on the retaining plate by pushing on a catch engagement.

17. The wiper arm according to claim 16 , wherein the electrical connecting element on the wiper arm side and a housing for the electrical connecting element move
