Abstract

Assembly for the production of a wiping system, comprising a terminal part ( 2 ) of a wiper arm designed to move a wiper blade ( 3 ) over the surface to be wiped and a hydraulic connector ( 30 ) comprising at least one piping element ( 31, 32 ) for conveying a liquid to the wiper blade ( 3 ), the said terminal part comprising at least one means ( 8 ) for supporting the said hydraulic connector ensuring that it is held longitudinally with reference to the wiper arm. It is characterized in that the said supporting means allows a movement of the said hydraulic connector ( 30 ) in a direction convergent with the longitudinal direction.

First claim

The invention claimed is:

1. A wiping system connection device comprising:
a wiper blade ( 3 ),
an assembly comprising a terminal part ( 2 ) of a wiper arm ( 1 ) designed to move the wiper blade ( 3 ), and a hydraulic connector ( 30 ),
a mechanical connector ( 10 ) fixed to the wiper blade in order to attach the wiper blade to the wiper arm ( 1 ) by means of an adapter ( 20 ) and the hydraulic connector ( 30 ),
the adapter being inserted between the wiper arm ( 1 ) and the mechanical connector ( 10 ) in order to allow the mechanical connector ( 10 ) to rotate relative to the wiper arm ( 1 ) between a position of use and a position of service,
the hydraulic connector ( 30 ) comprising at least one piping element ( 31 , 32 ) for conveying a liquid to the wiper blade ( 3 ), and

the terminal part extending in a longitudinal direction and comprising at least one means ( 8 ) for supporting the hydraulic connector ( 30 ) ensuring that it is held in the longitudinal direction, wherein the supporting means allows a movement of the hydraulic connector ( 30 ) in a direction that crosses the longitudinal direction,
wherein the mechanical connector ( 10 ) comprises at least one locking means ( 14 ) for locking the said hydraulic connector ( 30 ) onto the mechanical connector ( 10 ).

2. The device according to claim 1 , in which the movement allows the hydraulic connector ( 30 ) to move closer to or further from the terminal part ( 2 ).

3. The device according to claim 1 , in which the supporting means ( 8 ) allows the hydraulic connector ( 30 ) to rotate relative to the terminal part ( 2 ).

4. The device according to claim 3 , in which the movement and the rotation take place in a plane passing through the said longitudinal direction and perpendicular to a plane swept by the wiper arm when wiping.

5. The device according to claim 1 , in which the hydraulic connector comprises at least one lateral excrescence ( 33 , 133 , 233 ), the supporting means comprising at least one slot ( 9 ) in which the at least one excrescence ( 33 , 133 , 233 ) is housed.

6. The device according to claim 5 , in which the at least one slot ( 9 ) has a shape of a groove extending in the said plane and capable of guiding the at least one excrescence ( 33 , 133 , 233 ) in a movement of the hydraulic connector ( 30 ) closer to or further from the terminal part ( 2 ).

7. The device according to claim 6 , in which the said hydraulic connector comprises a rotation-immobilization lock ( 133 , 234 ) and the said supporting means ( 8 ) comprises a device ( 135 , 235 ) for immobilizing the rotation of the hydraulic connector by interaction with the said lock, when the said hydraulic connector is in a position of maximum distance from a segment of the wiper arm ( 1 ).

8. The device according to claim 7 , in which the said rotation-immobilization device ( 135 , 235 ) forms a hard spot for the passage of the said lock ( 133 , 234 ) into and out of a rotation-immobilization position.

9. The device according to claim 7 , in which the immobilization lock is a ridge ( 133 ) extending longitudinally and the immobilization device is a longitudinal narrowing ( 139 ) of the at least one slot ( 9 ).

10. The device according to claim 7 , in which the immobilization lock is a ridge ( 234 ) extending longitudinally and the immobilization device is a tooth of a tab ( 235 ) that can flex in a direction perpendicular to a plane of movement of the hydraulic connector ( 30 ).

11. The device according to claim 1 , in which the locking means is an arm ( 14 ) originating from the mechanical connector ( 10 ) capable of interacting with a lock ( 38 ) which extends laterally from the hydraulic connector ( 30 ).

12. The device according to claim 11 , in which the said locking means forms a hard spot for the passage of the said lock into and out of the locked position.

13. The device according to claim 12 , in which the said lock is a trunnion ( 38 ) and in which the arm ( 14 ) is slotted in the longitudinal direction in order to form two parallel branches ( 14 a , 14 b ) which have, between them, a circular cutout formed to receive the said trunnion ( 38 ).
