Embodiment Construction

[0037] In all the figures, a wiper for a vehicle windscreen is shown in cross-section, comprising a longitudinal base 10 formed of semi-rigid extruded plastic material. According to the "flexible blade" or "flat blade" technology, this base 10 comprises a recess 11 for receiving a metal reinforcing bar 20 or "ridge" extending substantially over the entire length of the wiper. The base 10 also includes longitudinal jaws 12 into which a wiper blade 30 formed of elastomer is incorporated.

[0038] An appendage 40 obtained by extrusion independent of the base 10 is assembled and fixed in the longitudinal base 10 . In the figures, the accessory 40 comprises a liquid spraying device formed by at least one longitudinal tube 42a, 42b pierced with holes 421a, 421b to be able to spray washer liquid, for example onto the windscreen of the vehicle. The appendage 40 usually consists of only one material, here an extruded elastomer.

[0039] Furthermore, it can be noted that in the figure...

According to the invention, the wiper further includes means (60a, 60b) for heating the washing liquid, said heating means being included in the tubes (42a, 42b) of the accessory (40).

Description

[0001] This application is a divisional application with application number 200980110039.6 and titled "Wiper for Vehicle Windshield", and the filing date is March 23, 2009. technical field [0002] The invention relates to a wiper for a vehicle windshield. Background technique [0003] Today there exists a technology related to windscreen wipers for vehicles called "flexible blades" or "flat blades", typical examples of which are disclosed in International Application No. WO2007 / 000346. [0004] This "flat blade" technology consists of a structure built around a central member comprising a longitudinal base of semi-rigid material onto which various other functional members are added. [0005] The first functional member is a metal rod housed in the longitudinal cavity of the base. This metal rod has a dual function, on the one hand, to provide the rigidity required for proper mechanical properties of the entire wiper, and to provide distribution of the pressure exerted by t...
