AI Technical Summary

Problems solved by technology

The spray device sprays the liquid in the direction that it is held, regardless of the position of the wiper relative to the arm, which causes problems
This is because, for example, these orientations are optimized for correct wetting of the windshield when the blade is in the middle of the windshield, but when the blade is at the side of the windshield, this is no longer optimal, resulting in excessive consumption of washing fluid and Poor cleaning of the windshield

Embodiment Construction

[0037] It should be noted that the accompanying drawings explain the invention in detail for the purpose of carrying it out, and that said drawings can of course be used to better define the invention if necessary.

[0038] In the following description, the terms longitudinal or lateral refer to the orientation of the wiper blade or the driver arm. The longitudinal direction corresponds to the main axis along which the blade or arm extends, while the lateral orientation corresponds to parallel lines, i.e., straight lines which straddle the longitudinal direction, especially in the plane in which the blade or arm rotates, in relation to the blade or arm The longitudinal axis is at right angles. For the longitudinal direction, the terms outer and inner are determined with respect to the point at which the blade is fixed to the arm, the term inner corresponding to the portion in which the arm and half-blade extend, or are fixed relative to the arm to the point at which the vehicl...

Abstract

An arm (14) for driving a wiper blade (12) of a vehicle wiper (10), in particular a motor vehicle, comprising an end piece (28) for fixing to the wiper blade, the arm further comprising A spray nozzle (40) for spraying fluid, such as washing fluid, characterized in that the spray nozzle is mounted to pivot about a pivot pin directly fixed or attached to said end piece, and in that the The spray nozzle includes means configured to cooperate with the wiper blade to pivot the spray nozzle about the pin.

Description

technical field [0001] The invention relates to a wiper arm for a vehicle, in particular a motor vehicle, comprising an end piece carrying a spray nozzle for spraying a fluid, such as a washing fluid. Background technique [0002] Motor vehicles are usually equipped with wipers for wiping the windshield and preventing the driver's view of his surroundings from being disturbed. These wipers generally consist of an angularly reciprocating drive arm, and an elongated blade which itself carries a blade rubber made of elastic material. These wiper rubber pieces rub against the windshield and displace the water, taking it out of the driver's field of vision. The blade is manufactured in traditional versions in the form of an articulated frame which holds the rubber piece of the blade at a number of discrete points, giving it curvature, allowing it to conform to any curvature the windshield may have, or more recently called a "flat blade". In the version of the "blade" wiper, it ...
