Abstract

The invention relates to a motor vehicle windshield wiper, comprising: a windshield wiper blade (42) that is hinged onto a windshield wiper arm (41) by means of an arm/blade connector (43, 44, 45, 51); and a washing liquid-spraying device (47) that is arranged on the windshield wiper blade and connected by means of a Connecting device (49, 53, 57) to a washing liquid delivery channel (46) that extends at least partially along the windshield wiper arm. Said windshield wiper is characterized in that the Connecting device is built into the arm/blade connector so as to automatically connect the spraying device to the delivery channel when Connecting the windshield wiper blade onto the windshield wiper arm and so as to automatically detach the spraying device from the delivery channel when disconnecting the windshield wiper blade from the windshield wiper arm.

Claims

1. A windshield wiper for automotive vehicle comprising:

a windshield wiper blade articulated on a windshield wiper arm with an arm-blade connector, and a washer fluid projection device arranged on the windshield wiper blade and connected by a coupling device to a washer fluid supply channel extending at least in part along the windshield wiper arm;

wherein the coupling device is integrated in the arm-blade connector for automatic coupling of the projection device with the supply channel during the connection of the windshield wiper blade to the windshield wiper arm and for automatic decoupling of the projection device from the supply channel during the disconnection of the windshield wiper blade from the windshield wiper arm;

wherein the arm-blade connector comprises a connector first portion integral with the arm and a connector second portion integral with the blade;

wherein the coupling device comprises a coupling first part integral with the arm and a coupling second part integral with the blade, wherein the coupling first part is integrated in the connector first portion and the coupling second part is integrated in the connector second portion, making the coupling device integral with the arm-blade connector;

the connector first portion defining an opening and the connector second portion including a latch-lever suitable to be positioned in said opening to ensure the connection between the arm and the blade, wherein the latch-lever is used to lock the coupling first part and the coupling second part together; and

wherein the latch-lever is pin-shaped and comprises an upper zone with an opening sized to allow for the passage of a head-shaped part of the first part of the coupling device and a lower zone with an opening sized to prevent the passage of the head-shaped part of the first part of the coupling device, said opening of said lower zone being smaller than the opening of the upper zone.

2. A windshield wiper according to claim 1, wherein the arm-blade connector is used to lock the coupling device during the connection.

3. The windshield wiper according to claim 1, wherein the first part of the coupling device defines an enlarged head that is suitable for insertion inside a head-receiving opening of the second part of the coupling device.

4. The windshield wiper according to claim 3, further comprising a ring seal installed in the head-receiving opening.

5. An automotive vehicle equipped with a windshield according to claim 1.
