Definitions

• the present invention relates to the cleaning system of the windshield or the rear window of a vehicle, especially automobile.
• the windshield or rear window of the vehicle is cleaned by a nozzle usually located for cleaning the windshield, on the hood of the vehicle, or for cleaning the rear window. , on the outskirts of this telescope.
• This nozzle projects on the glass to clean a detergent which is then scraped by the wipers of the vehicle.
• the invention therefore aims in particular to remedy this disadvantage and to propose an improved wiper blade for a more controlled or more uniform distribution of the cleaning liquid.
• a wiper blade comprising a longitudinal support along which is fixed a wiper blade intended to be in contact with a window, the blade having an inverted gutter extending substantially parallel to the wiper blade, and having a longitudinal opening intended to be opposite the window, the broom having a nozzle fixed near one end of the channel, adapted to indirectly spread a laminar jet of liquid of cleaning in the gutter substantially in the longitudinal direction thereof characterized in that the gutter comprises means for changing the flow of the cleaning liquid sprayed inside thereof.
• the means for modifying the flow of the cleaning liquid comprise a modification of the size of the inner section of the gutter.
• the change in the size of the inner section of the gutter is a function of the distance of the section relative to the nozzle.
• the inner section of the gutter is modified in an ad hoc manner.
• the means for modifying the flow of the cleaning liquid in a specific manner comprise a plurality of walls located inside the gutter and oriented substantially orthogonal to the longitudinal axis of the gutter, each of the walls comprising an opening.
• the size of the openings decreases from one end to the other of the gutter, the wall having the widest opening being located near the nozzle.
• the inner section of the gutter is continuously modified.
• the inner section of the gutter decreases from one end to the other of the gutter, the largest section being located near the nozzle.
• the invention also relates to a vehicle wiper comprising a broom according to the invention.
• the invention also relates to a vehicle comprising a windscreen wiper according to the invention.

• the accompanying drawings may not only serve to complete the invention, but also contribute to its definition, if any.
• the invention proposes an improvement of a windscreen wiper blade with an inverted gutter.
• the gutter according to the invention comprises means for modifying the flow rate of the cleaning liquid spread inside it. These means make it possible to distribute the cleaning liquid more evenly on the squeegee or at least to better control its distribution.
• Means for changing the flow of the cleaning liquid include a change in the size of the inner section of the gutter.
• the modification of the inner section of the gutter makes it possible to modify the flow rate of the liquid sprayed inside it. These section modifications are chosen for example so as to evenly distribute the liquid on the squeegee.
• the changes of the inner section of the gutter can be made according to different variants.
• the characteristics presented below are common to the various embodiments of the gutter.
• Figure 1 illustrates a wiper blade according to one embodiment of the invention.
• Figure 2 illustrates a sectional view of a wiper blade in a plane A orthogonal to the longitudinal axis of the wiper blade and located at a nozzle.
• the wiper blade 1 has a curved longitudinal shape to fit the curve of the window to be cleaned. It comprises a longitudinal support 10 over its entire length a wiper blade 12.
• the wiper blade 12 is of elastically deformable material, which is intended to be in contact with the window.
• the wiper blade 1 carries a nozzle for dispensing cleaning liquid, which comprises a nozzle 32.
• the dispensing nozzle 3 is attached to one end of the blade 1.
• Jet 32 receives the cleaning fluid by a connection pipe (not shown) of the nozzle 3, to which is connected a flexible fluid inlet pipe, and spreads this fluid forming a laminar jet (that is to say a straight stream and without dispersion) of fluid substantially in the longitudinal direction of the wiper blade 1 towards the end opposite the nozzle.
• the wiper blade 1 also has, over most of its length, an inverted channel 13 having a U-shaped cross section.
• These two edges of the channel 13 define a longitudinal opening of the channel 13, in the direction intended to be facing the window.
• the inverted channel 13 is also open at an end placed so that the nozzle 32 of the dispensing nozzle 3 spreads the liquid in the channel 13 by this open end.
• the jet of cleaning liquid thus diffused in the form of a laminar jet, substantially in the longitudinal direction of the blade 1, is protected from aerodynamic disturbances by the channel 13.
• the channel 13 has for example a curved shape in the curved shape of the blade 1, so that it guides the laminar jet of liquid spread by the nozzle 32 so that it follows the shape of the blade 1.
• the other end of the channel 13 is closed, as shown in Figure 1, to allow the excess cleaning liquid to fall by gravity in front of the squeegee to prevent the flow of excess liquid to the outside of the broom 1.
• the channel 13 may also be open at both ends.
• the inverted channel can be integrated into the profile flexible forming the raclette. It extends in this case substantially parallel to the wiper blade of the squeegee.
• Figures 3a and 3b illustrate sectional views, respectively in planes B and C, of an embodiment of the first variant.
• the means for modifying the flow of the cleaning liquid in a specific manner comprise a plurality of walls 31, 33 located inside the gutter and oriented substantially orthogonal to the axis. longitudinal of the gutter, each of the walls having an opening.
• the size of the openings decreases from one end to the other of the gutter, the wall having the widest opening 31 being located near the nozzle.
• the size of the openings decreases proportionally with respect to its distance to the nozzle.
• the plane B is located at the first third of the wiper blade and the plane C at the second third.
• the distance between the plane B and the end of the windscreen wiper is two times smaller than the distance from the plane B with the opposite end of the windscreen wiper.
• the distance between the plane C the end of the windscreen wiper is twice as large as the distance from the plane C with the end of the wiper opposite the nozzle.
• a first wall 31 is located at the plane B.
• the first wall 31 is rectangular in shape. It is arranged in the lower part of the gutter, that is to say the part closest to the squeegee.
• a second wall 33 is located at the plane C. The second wall 33 is also rectangular.
• the first wall 31 reduces the inner section of the gutter 30% and the second 60%, these values being given by way of non-limiting example.
• Figures 4a and 4b illustrate sectional views, respectively in planes B and C, of an embodiment of the second variant.
• the plane B is located at the first third of the wiper blade and the plane C at the second third.
• the inner section 41 of the gutter decreases from one end to the other of the gutter, the largest section being located near the nozzle.
• the section of the gutter decreases proportionally with respect to its distance to the nozzle.
• the shape of the section is also modified. It is U-shaped at the jet. The section gradually takes a flared shape halfway up the gutter.
