Abstract

The invention is directed to a wiper arm arrangement comprising a wiper bar (10), a coupling unit (12) and a fastening unit (14) for securing the coupling unit (12) to the wiper bar (10). According to the invention, the coupling unit (12) has a crimped profile (16, 54) which, in a mounted state, is to be connected to a washer fluid hose (18).

First claim

What is claimed is:

1. A wiper arm arrangement comprising an elongate wiper bar ( 10 ) that extends along a longitudinal direction ( 24 ), a coupling unit ( 12 ), a washer fluid hose ( 18 ), and a fastening unit ( 14 ) for securing the coupling unit ( 12 ) to the wiper bar ( 10 ), wherein the fastening unit ( 14 ) includes a main crimped profile ( 26 , 46 ) having lugs bent around a portion of the wiper bar ( 10 ) to hold the wiper bar ( 10 ), characterized in that the coupling unit ( 12 ) has a crimped profile ( 16 , 54 ) having lugs which are bent around the washer fluid hose ( 18 ) to hold the washer fluid hose ( 18 ) while the washer fluid hose ( 18 ) rests on the lugs of the main crimped profile ( 26 , 46 ), such that the lugs of the main crimped profile ( 26 , 46 ) are disposed between the wiper bar ( 10 ) and the washer fluid hose ( 18 ), and wherein the lugs of the main crimped profile are spaced from the lugs of the crimped profile of the coupling unit by a gap ( 28 ) along the wiper bar longitudinal direction ( 24 ).

2. The wiper arm arrangement according to claim 1 , characterized in that the lugs of the coupling unit ( 16 , 54 ) are configured to be disposed at the same height in a wiper bar longitudinal direction ( 24 ) in the mounted state.

3. The wiper arm arrangement according to claim 1 , characterized in that the coupling unit ( 12 ) comprises a wiper arm adapter ( 30 ), which is configured to be coupled to a wiper blade adapter.

4. The wiper arm arrangement according to claim 1 , characterized in that the coupling unit ( 12 ) comprises an articulation piece ( 32 ), which is configured to be coupled to a drive shaft fastening part ( 34 ).

5. The wiper arm arrangement according to claim 1 , characterized in that the crimped profile ( 16 , 54 ) of the coupling unit ( 12 ) is made at least substantially of metal.

6. A method for forming the wiper arm arrangement of claim 1 , the method comprising crimping the lugs of the fastening unit ( 14 ) around the wiper bar ( 10 ), resting the washer fluid hose ( 18 ) on the lugs of the fastening unit ( 14 ), and crimping the lugs of the crimped profile ( 16 , 54 ) of the coupling unit ( 12 ) around the washer fluid hose ( 18 ).
