Hydraulic connector, particularly for motor vehicle windscreen wiper system

Abstract

The connector (1) has an inlet coupling (5) for connection to a cleaning and de-icing fluid feed, and distributors (7, 8) provided with outlet couplings (9-11). The outlet couplings are connected to fluid carrying ramps (3, 4) of a wiper blade (2). An internal path carries the fluid from the inlet coupling to one of the distributors. The inlet coupling is oriented in parallel to or perpendicular to the distributor, where the connector is formed of a mono block that is obtained through molding of plastic material. An independent claim is also included for a windscreen wiper system for a motor vehicle, comprising a wiper blade connected to an actuating arm by an adapter.

Description

technical field [0001] The object of the present invention is a hydraulic connector, more particularly for use in, for example, windscreen wiper systems for motor vehicles. Other objects of the invention are as follows: windshield wiper system provided with drive arm, wiper blade and connector; only one drive arm provided with connector; only one wiper blade provided with connector. Background technique [0002] Windshield wiper systems, such as those used for cleaning or deicing motor vehicle windshields, generally include a drive arm connected to a source of fluid or cleaning liquid and / or deicing liquid and to a motor and coupled to the drive arm. Arm wiper blade. [0003] During wiping there is a relative displacement between the arm and the blade, so that the coupling between the arm and the blade must enable rotation of the blade relative to the arm. [0004] In addition, the blade must be easily coupled and detached from the arm to enable it to be replaced or mainta...

AI Technical Summary

Problems solved by technology

[0013] The problem with this connection element is that it is complex and expensive to produce and assemble

[0014] Also, the attachment / detachment of the wiper blade is not simple

[0015] Disassembly of the dispenser from the adapter is also a risk due to the relative displacement between the arm and the wiper blade

[0016] In addition, the inlet coupling leads directly to the distributor on its side, which makes it difficult to protect the fluid inlet pipes and hide such pipes with a better appearance

[0017] Another problem arises from overpressure stresses that are generated generally parallel to the wiper blades, and thus to the distributor, since the fluid inlet tube is generally hidden and guided along the arms, and therefore in connections parallel to this blade orientation. open at
