Abstract

The invention relates to a hydraulic connector, particularly for a motor vehicle windscreen wiper system. The connector is designed to be mounted on a wiper blade fitted with a perforated pipe carrying cleaning and de-icing fluid, and comprises at least one inlet coupling suitable for connection to a fluid feed, and at least one distributor provided with at least one outlet coupling designed to be connected to the perforated pipe. The connector also includes at least one internal path for carrying the fluid from the inlet coupling to the distributor. Thus, by means of the presence of the internal path through the connector, the inlet coupling can be positioned at various locations on the connector, without feeding directly into the distributor.

First claim

The invention claimed is:

1. A windscreen wiper system comprising a wiper blade fitted with at least a perforated pipe carrying fluid, and connected to a drive arm by an adaptor, wherein the adaptor is rotatingly connected to a connector by a hinge axis, the connector comprising:
at least one inlet coupling suitable for connection to a fluid feed;
at least one distributor provided with at least one outlet coupling configured to be connected to the perforated pipe;
at least one internal path for carrying the fluid from the at least one inlet coupling to the at least one distributor;
a first part made of one piece moulded in a plastic material, the first part comprising the at least one inlet coupling and a first portion of the at least one internal path;
a second part made of one piece having a different shape than the first part and moulded in a plastic material, the second part comprising a remainder of the at least one internal path and at least a part of the at least one distributor; and
a deflector formed in two parts connected on either side of the connector, wherein the deflector receives a mount, and wherein the mount receives in turn a strip and a wiping blade,
wherein the first and the second parts are sealingly assembled to form the connector,
wherein the connector is connected by the at least one outlet coupling thereof to the perforated pipe, and
wherein the connector is connected by the at least one inlet coupling thereof to one or two fluid feeds.

2. The windscreen wiper system according to claim 1 , wherein the at least one inlet coupling is oriented parallel to the at least one distributor.

3. The windscreen wiper system according to claim 2 , wherein the at least one inlet coupling comprises two inlet couplings for connection to the fluid feed.

4. The windscreen wiper system according to claim 2 ,
wherein the connector is suitable for assembling to a wiper blade provided with two perforated pipes carrying fluid, and
wherein the at least one distributor comprises two distributors, each of the two distributors being provided with at least one outlet coupling configured to be connected to either one of the two perforated pipes.

5. The windscreen wiper system according to claim 2 ,
wherein the at least one distributor is provided with two opposite outlet couplings, and
wherein the two opposite outlet couplings are configured to be connected to the perforated pipe.

6. The windscreen wiper system according to claim 2 , wherein the at least one distributor is provided with a port in a middle thereof.

7. The windscreen wiper system according to claim 2 , wherein the at least one inlet coupling is a male coupling that is configured to be connected to a female fluid feed.

8. The windscreen wiper system according to claim 2 , wherein the at least one inlet coupling is a female coupling that is configured to be connected to a male fluid feed.

9. The windscreen wiper system according to claim 1 , wherein the at least one inlet cowling comprises two inlet couplings suitable for connection to the fluid feed.

10. The windscreen wiper system according to claim 1 ,
wherein the connector is suitable for assembling to a wiper blade provided with two perforated pipes carrying fluid, and
wherein the at least one distributor comprises two distributors, each of the two distributors being provided with at least one outlet coupling configured to be connected to either one of the two perforated pipes.

11. The windscreen wiper system according to claim 1 ,
wherein the at least one distributor is provided with two opposite outlet couplings, and
wherein the two opposite outlet couplings are configured to be connected to the perforated pipe.

12. The windscreen wiper system according to claim 1 , wherein the at least one distributor is provided with a port in a middle thereof.

13. The windscreen wiper system according to claim 1 , wherein the at least one inlet coupling is a male coupling that is configured to be connected to a female fluid feed.

14. The windscreen wiper system according to claim 1 , wherein the at least one inlet coupling is a female coupling that is configured to be connected to a male fluid feed.
