Problems solved by technology

This disadvantage is even more acute when the temperature is low
[0011] On the other hand, in order to insert the connector for connection to the drive of the wiper blade assembly into the coextrusion, the part has to be cut in two, thus causing problems with the connection of the part to the connector
In the case where longitudinal channels for transporting washing fluid are integrated into the structure, the problem of continuity of fluid circulation between the two sections also arises

Embodiment Construction

[0049] Figure 1a A cross-sectional view is shown of a wiper blade assembly for a motor vehicle window comprising a longitudinal support 10 made of some extruded semi-rigid plastic material. This support 10, according to the "flat blade" technology, comprises a cavity 11 for accommodating a pressing metal rod 20 or "ridge", which has a flat shape and extends substantially over the entire length of the wiper blade assembly extend. This support 10 also comprises a longitudinal holder 12 into which an elastomeric wiper blade 30 is introduced.

[0050] Such as Figure 1a As shown, the attachment 40 is fitted and fixed to the longitudinal support 10 and is made by extrusion, independent of the support 10 . exist Figure 1a In the example shown, the accessory 40 is a wind deflector 41 comprising a device 42 for distributing and spraying fluid and comprising two longitudinal channels 42a, 42b having holes 421a, 421b for allowing, for example Spray washer fluid on the windows of the...

Abstract

The invention relates to a wiper blade assembly for the windows of a motor vehicle, comprising a longitudinal support (10) intended to receive a pressure application vertebra (20) and a wiper blade (30) and a wiper accessory (40) carrying a device (42a, 42b) for distributing and projecting a washer liquid wherein the accessory is intended to be assembled with the longitudinal support (10). According to the invention, the longitudinal support (10) comprises means for fixing said accessory (40) on said support.

Description

technical field [0001] The present invention relates to wiper blade assemblies for motor vehicle windows. [0002] The invention also relates to an accessory for a wiper blade assembly and a wiper device for motor vehicle windows incorporating the wiper blade assembly. Background technique [0003] There currently exists technology for wiper blade assemblies for motor vehicle windows known as "flat blades", an example of an embodiment is described in International Application WO 2007 / 000346. [0004] This "flat blade" technology consists of a structure built around a solid longitudinal member comprising two functionally distinct parts. [0005] The first part is a support of semi-rigid and flexible plastic material, which comprises, on the one hand, a chamber housing a pressure application rod, usually metallic and also covered by Called "vertebra", the support on the other hand comprises a holder carrying an elastomeric wiper blade. [0006] The second part of the strong...
