Abstract

The invention relates to a wiper arm ( 10 ) for a windscreen wiper system of a motor vehicle, with a receiving region ( 11 ) for a wiper blade adapter ( 55 ) consisting of several wiper blade adapter elements ( 56; 56 a, 57; 57 a, 58 ), wherein the wiper arm ( 10 ) has a securing element ( 65; 65 a ) which at least partially covers the receiving region ( 11 ), wherein the securing element ( 65; 65 a ) is constructed such that it is movable between a dismantling position, in which the wiper blade adapter ( 55 ) is removed from the receiving region ( 11 ), and a locking position, in which the wiper blade adapter ( 55 ) is held in the receiving region ( 11 ), wherein an adapter element ( 75 ) serving to supply washing fluid and/or to supply power is arranged in the receiving region ( 11 ), and wherein the adapter element ( 75 ), on the one hand, can be connected to a supply line for the washing fluid and/or to an electric line ( 79 ) and, on the other hand, has an outlet ( 77 ) for the washing fluid and/or a plug connection ( 78 ) for the electric line ( 79 ), wherein the outlet ( 77 ) and/or the plug connection ( 78 ) can be connected to a first wiper blade adapter element ( 56; 56 a ).

First claim

1 . A wiper arm for a windscreen wiper system of a motor vehicle, comprising:
a receiving region for a wiper blade adapter consisting of several wiper blade adapter elements; and a securing element which at least partially covers the receiving region, wherein the securing element is movable between a dismantling position, in which the wiper blade adapter is removed from the receiving region, and a locking position, in which the wiper blade adapter is held in the receiving region, wherein, in the receiving region, an adapter element is arranged for the supplying of washing fluid and/or for the current supply, and wherein the adapter element is able to be connected with a supply line for the washing fluid and/or with an electric line, and has an outlet for the washing fluid and/or a plug connection for the electric line, wherein the outlet and/or the plug connection is able to be connected with a first wiper blade adapter element, wherein the first wiper blade adapter element, connectable with the adapter element, is coupled with the securing element such that according to the position of the securing element in the locking position, the adapter element is connected with the first wiper blade adapter element and in the dismantling position, the adapter element is separated from the first wiper blade adapter element.

2 . The wiper arm according to claim 1 , wherein the coupling of the securing element with the first wiper blade adapter element takes place via a form-fitting connection, which has a holding projection on the securing element or on the first wiper blade adapter element, which engages into an opening on the first wiper blade adapter element or on the securing element.

3 . The wiper arm according to claim 1 , wherein the receiving region has a U-shaped cross-section with two side walls parallel to one another, and with a transverse wall connecting the two side walls, and with at least two receiving openings formed on the side walls for receiving extensions arranged on the wiper blade adapter in a mounting or respectively dismantling direction running at least substantially perpendicularly to the transverse wall, wherein the securing element in a mounting or respectively dismantling position of the wiper blade adapter exposes the receiving openings.

4 . The wiper arm according to claim 1 , wherein the outlet and/or the plug connection is aligned with the mounting or respectively dismantling direction of the securing element.

5 . The wiper arm according to claim 1 , wherein the adapter element has respectively a holding protuberance on the side facing the side wall, which projects into a holding opening, having a closed cross-section, of the side wall.

6 . A wiper blade for fastening to a wiper arm according to claim 1 , with a wiper blade adapter consisting of several wiper blade adapter elements, which is constructed to be received in a wiper arm, wherein the mounting or respectively dismantling direction of the wiper blade adapter on or respectively from the wiper arm runs substantially perpendicularly to the longitudinal axis of the wiper blade, wherein
on a first wiper blade adapter element of the wiper blade adapter an inlet is constructed for the supplying of a washing fluid and/or a connection element is constructed for the current supply, and that the inlet and/or the connection element is aligned perpendicularly to the mounting or respectively dismantling direction of the wiper blade adapter on the wiper arm.

7 . The wiper blade according to claim 6 , wherein the wiper blade adapter has at least three wiper blade adapter elements, the first wiper blade adapter element, which is constructed to be connected with an adapter element on the wiper arm, a second wiper blade adapter element, on the side walls of which extensions are constructed for introducing in receiving openings of a wiper arm, and a third wiper blade adapter element, which is connected with a wiper blade body.

8 . The wiper blade according to claim 7 , wherein the second and the third wiper blade adapter elements are arranged swivelably with respect to one another, and that the first wiper blade adapter element is arranged swivelably to the third wiper blade adapter element and movably in a translatory manner to the second wiper blade adapter element.

9 . The wiper blade according to claim 8 , wherein the first wiper blade adapter element has first extensions, which engage in recesses of the third wiper blade adapter element to achieve the swivelability between the first and the third wiper blade adapter elements.

10 . The wiper blade according to claim 9 , wherein the first extensions form a stop for delimitation of the swivel angle between the first and the third wiper blade adapter elements.

11 . The wiper blade according to claim 8 , wherein on the first wiper blade adapter element second extensions or holding webs are constructed, which engage into a guide or into a slot-shaped receiving opening to achieve the translatory movement between the first and the second wiper blade adapter elements.

12 . The wiper blade according to claim 8 , wherein on the third wiper blade adapter element third cylindrical extensions are constructed which, for forming a latching connection in a mounting or respectively dismantling position of the wiper blade adapter, engage in holding openings which are formed on the second wiper blade adapter element.

13 . The wiper blade according to claim 8 , wherein on the first wiper blade adapter element fourth cylindrical extensions are constructed which, at least for delimitation of the translatory movement of the first wiper blade adapter element, cooperate with holding openings formed on the third wiper blade adapter element.

14 . A wiper device for cleaning vehicle windows, comprising a wiper arm according to claim 1 and a wiper blade with a wiper blade adapter consisting of several wiper blade adapter elements, which is constructed to be received in the wiper arm, wherein the mounting or respectively dismantling direction of the wiper blade adapter on or respectively from the wiper arm runs substantially perpendicularly to the longitudinal axis of the wiper blade, wherein on a first wiper blade adapter element of the wiper blade adapter an inlet is constructed for the supplying of a washing fluid and/or a connection element is constructed for the current supply, and that the inlet and/or the connection element is aligned perpendicularly to the mounting or respectively dismantling direction of the wiper blade adapter on the wiper arm.
