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.

Claims

1. Assembly for the production of a wiping system, comprising a terminal part (2) of a wiper arm (1) designed to move a wiper blade (3) 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 extending in a longitudinal direction and comprising at least one means (8) for supporting the said hydraulic connector (30) ensuring that it is held in the longitudinal direction, characterized in that the said supporting means allows a movement of the said hydraulic connector (30) in a direction convergent with the longitudinal direction.

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

4. Assembly 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 the plane swept by the wiper arm when wiping.

5. Assembly 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 said excrescence (33, 133, 233) is housed.

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

7. Assembly 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 the wiper arm (1).

8. Assembly 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. Assembly 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 slot (9).

10. Assembly 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 the direction perpendicular to the plane of movement of the hydraulic connector (30).

11. Wiping-system connection device comprising a terminal part (2) of a wiper arm (1), a wiper blade (3), a mechanical connector (10) fixed to the said wiper blade in order to attach it to the wiper arm (I) by means of an adapter (20) and a hydraulic connector (30) comprising at least one piping element (31, 32) for conveying a liquid to the wiper blade (3), the said adapter being inserted between the wiper arm (I) 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, characterized in that it comprises an assembly formed of a terminal part (2) and a hydraulic connector (30) according to one of the preceding claims.

12. Device according to claim 11, in which the mechanical connector (10) comprises at least one locking means (14) for locking the said hydraulic connector (30) onto the mechanical connector (10).

13. Device according to claim 12, 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).

14. Device according to claim 13, in which the said locking means forms a hard spot for the passage of the said lock into and out of the locked position.

15. Device according to claim 14, 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 (14a, 14b) which have, between them, a circular cutout formed to receive the said trunnion (38).
