Description
- The invention relates to a windscreen wiper for a motor vehicle window. More particularly, the invention relates to a windscreen wiper comprising an aerodynamic deflector and at least one integrated nozzle for windscreen washer liquid.
- When a vehicle is moving at high speed, its windscreen wiper or wipers and also the wiper arm thereof are subjected to air streams that can lift the windscreen wiper in places from the window. This lifting leaves a film of water and/or of windscreen washer liquid on the surface to be wiped and ultimately hampers the visibility of the driver. In addition, the jets of windscreen washer liquid projected by the windscreen wiper are also subjected to these air streams and also to air streams that arise from disturbances brought about by the windscreen wiper or wipers and also the wiper arm thereof, these disturbances modifying the trajectories of said jets. Consequently, the windscreen washer liquid is poorly distributed over the window of the vehicle, and the cleaning thereof is compromised.
- A prior
art windscreen wiper 111 as shown inFIG. 1 is known. Such a priorart windscreen wiper 111 comprises awiper blade 501, anaerodynamic deflector 901 located above thewiper blade 501 and at least one nozzle for windscreen washer liquid, said nozzle comprising afluid circulation duct orifice 350. When the priorart windscreen wiper 111 is in operation, that is to say when it is wiping thewindow 3 of the vehicle, it is subjected to theair stream 21 that flows towards anupstream face 231 of theaerodynamic deflector 901, and to therecirculating air stream 41 that flows in the opposite direction towards adownstream face 241 of theaerodynamic deflector 901. Theaerodynamic deflector 901 diverts a part of theair streams 21 upwards. Thus, theaerodynamic deflector 901 is subjected to an aerodynamic pressure force which tends to press it, and also the priorart windscreen wiper 111, towards thewindow 3. - However, the prior
art windscreen wiper 111 is not able to protect the jets ofwindscreen washer liquid 33 from theair streams windscreen washer liquid 33 is disturbed, for example a part of thewindscreen washer liquid 33 does not reach thewindow 3, and the efficacy of thewindscreen wiper 111 is compromised. - One of the aims of the present invention is to at least partially remedy this drawback of the prior art by proposing an improved windscreen wiper that is able to protect the jets of windscreen washer liquid from the air streams.

windscreen wiper 1 generally comprises awiper blade 5, at least onestiffening blade 7 and anaerodynamic deflector 9. Theseelements mount 11 of the windscreen wiper. Themount 11 is produced for example by moulding rigid or semi-rigid plastics material. - A lower part of the
windscreen wiper 1 comprises thewiper blade 5. To this end, themount 11 has two oppositelower ribs 12 having an “L”-shaped section that form hooks which delimit a downwardly openlower cavity 13. Thislower cavity 13 receives ahead 15 of the wiper blade. Thewiper blade 5 has alower scraper 17 intended to be in contact with thewindow 3 of the vehicle. Thewiper blade 5 is conventionally made of rubber or a natural or synthetic elastomer material produced by extrusion or moulded. - A central part of the
windscreen wiper 1 comprises thestiffening blade 7, having a substantially rectangular cross section, which is for example inserted into an upper part of themount 11. For this purpose, themount 11 delimits a hollowinternal housing 19 located in line with thelower cavity 13. Theinternal housing 19 has a substantially rectangular contour in which thestiffening blade 7 is received. Thisstiffening blade 7 is advantageously received with play so as to allow slight relative movements in particular in the longitudinal direction in order to allow thewindscreen wiper 1 to bend. In association with themount 11, it forms a structure of thewindscreen wiper 1 and gives thewindscreen wiper 1 its elasticity in the vertical and longitudinal plane, allowing the windscreen wiper to adapt to the shape and in particular the curve of the outer face or upper face of thewindow 3 to be wiped. Thestiffening blade 7 is produced for example from steel. - An upper part of the windscreen wiper comprises the
aerodynamic deflector 9. Theaerodynamic deflector 9 protects the windscreen wiper fromair streams 21 which flow along thewindow 3 to be wiped when the vehicle is moving. In particular, it slows the air streams and allows a pressure to be exerted on it and thus on thewindscreen wiper 1, this pressure pressing the latter against thewindow 3. - The
aerodynamic deflector 9 may have anupstream face 23 and adownstream face 24. The air streams 21 are slowed and diverted by theupstream face 23, with the result that thewindscreen wiper 1 is subjected to an aerodynamic pressure force which tends to press theaerodynamic deflector 9 and thewindscreen wiper 1 in the direction of thewindow 3. - According to the example illustrated, the cross section of the
upstream face 23 and also the cross section of thedownstream face 24 are substantially in the form of circular arcs. Of course, other shapes are possible, for example theupstream face 23 anddownstream face 24 may be substantially straight, forming an inclined plane. - It is, however, possible for the
deflector 9 not to have anupstream face 23 anddownstream face 24 and simply to have a shape which is planar on the top or slightly profiled and allowing sufficient slowing of the air streams to press thewindscreen wiper 1 against thewindow 3. - The
aerodynamic deflector 9 is produced for example by extrusion of a rigid or flexible synthetic material. - The
aerodynamic deflector 9 is assembled on themount 11. For this purpose, themount 11 comprises for example two oppositelateral ribs 25 having an “L”-shaped section that form hooks which delimit lateral recesses 27. The aerodynamic deflector has oppositelateral protrusions 29 having an “L”-shaped section that form hooks. The oppositelateral protrusions 29 are received in the lateral recesses 27 with play so as to allow slight relative movements in particular in the longitudinal direction. The hooks of thelateral ribs 25 and the hooks of thelateral protrusions 29 are in opposite directions. Thus, thedeflector 9 and themount 11 remain firmly joined together. - The
windscreen wiper 1 also comprises at least onefluid circulation duct windscreen washer liquid 33, represented by a solid arrow. In the examples shown inFIGS. 2 and 3 , thewindscreen wiper 1 comprises twocirculation ducts fluid circulation ducts orifice 35. The sprayingorifice 35 allows thewindscreen washer liquid 33 to be projected away from thewindscreen wiper 1. Preferably, thefluid circulation duct 31 comprises a plurality of sprayingorifices 35 that are longitudinally distributed. According to the examples shown, only one of thecirculation ducts 31 comprises avisible spraying orifice 35. The sprayingorifice 35 is directed substantially downwardly, that is to say in the direction of thewindow 3. More particularly, the sprayingorifice 35 has a sprayingdirection 37 represented by a double line. This sprayingdirection 37 may be at an angle α (visible inFIG. 3 ) with avertical axis 39 of thewiper blade 5. Thevertical axis 39 of thewiper blade 5 is shown by a dashed line; for better understanding, thisvertical axis 39 is plotted by translation along the transverse axis T at different locations in the figures. This angle α is acute, being for example between 0° and 45°. InFIG. 2 , the angle α is 0°, the jet ofwindscreen washer liquid 33 is projected parallel to thewiper blade 5 and directly towards thewindow 3. - In the example shown in
FIGS. 2 and 3 , theaerodynamic deflector 9 comprises twocirculation ducts mount 11. In a first variant, a singlefluid circulation duct windscreen wiper 1 is of the single spray bar type. According to the example illustrated, the downstreamfluid circulation duct 32 is connected to the supply. - According to a second variant, the two
circulation ducts windscreen wiper 1 is of the double spray bar type. The twocirculation ducts orifice 35. Therespective spraying directions 37 of these sprayingorifices 35 may be different. - Advantageously, a single model of
aerodynamic deflector 9 is extruded with twocirculation ducts windscreen washer liquid 33. Thus, this single model may be used for single spray bar or double spray bar windscreen wipers. In this way, the manufacturing costs are reduced. - The
windscreen wiper 1 comprises an improvedaerodynamic deflector 9 that not only guides the flow of the air streams such that thewindscreen wiper 1 remains in proper contact with thewindow 3, but also protects the jets ofwindscreen washer liquid 33 from the air streams 21, 41 on the upstream side and downstream side. Specifically, the air streams 21 diverted by theupstream face 23 of theaerodynamic deflector 9 recirculate on the downstream-face 24 side. The recirculation of the air streams is shown by thecurved arrow 41. - For this purpose, the
aerodynamic deflector 9 comprises at least one lowerlateral skirt wiper blade 5 and of the sprayingorifice 35. In the example illustrated, theaerodynamic deflector 9 comprises two lowerlateral skirts wiper blade 5. The spraying orifices 35 are thus located between thewiper blade 5 and the lowerlateral skirts windscreen washer liquid 33 projected from the sprayingorifices 35 is protected from the air streams 21, 41. Thewindscreen washer liquid 33 strikes thewindow 33 and cleaning is thus improved. - The lower
lateral skirts inclination direction wiper blade 5. Theinclination direction inclination direction vertical axis 39 of the wiper blade. This inclination angle β1, β2 is between 0° and 60°. The inclination angle β1, β2 is decided depending on the efficacy of washing and the desired aerodynamic performance. Preferably, the angle β1, β2 is non-zero, and the lowerlateral skirt wiper blade 5. - The lower
lateral skirt lateral skirt window 3 in spite of the pressing of the windscreen wiper on account of the air streams and also the wear of thelower scraper 17 over time. This length l1, l2 is decided depending on the efficacy of washing and the desired aerodynamic performance. - According to a variant shown in
FIG. 2 , the sprayingorifices 35 are directed substantially parallel to the vertical axis of the wiper blade. Thus, the jets ofliquid 33 protected from the air streams 21, 41 are directed substantially perpendicularly to thewindow 3 of the vehicle. - According to another variant shown in
FIG. 3 , the sprayingorifices 35 are directed towards the downstream lowerlateral skirt 44. Thus, the jets ofliquid 33 are projected onto the downstream lowerlateral skirt 44. When the jets ofliquid 33 strike the downstream lowerlateral skirt 44, they explode in a plurality ofdirections 44 before striking thewindow 3. Thus the windscreen washer liquid is distributed over a larger surface area of thewindow 3, thereby improving the cleaning of thewindow 3. - When the windscreen wiper is of the double spray bar type, the jets of liquid coming from the orifices of the upstream
fluid circulation duct 31 are projected in the direction of the upstream lowerlateral skirt 43. - According to another variant shown in
FIG. 5 , the lowerlateral skirt 43, 44 (only one lower lateral skirt is shown inFIG. 5 ) may have aprojection relief 49 directed in thesame spraying direction 37. The jet ofliquid 33 is thus projected in the direction of theprojection relief 49. On making contact therewith, it explodes in a plurality of directions (not shown), and thus the windscreen washer liquid is distributed over a larger surface area of thewindow 3, thereby improving the cleaning of thewindow 3 by avoiding the appearance of streaks. Theprojection relief 49 comprises for example a hole. - Advantageously, and as shown in
FIGS. 2 and 3 , theaerodynamic deflector 9 comprises two lowerlateral skirts wiper blade 5. One lower lateral skirt is thus located upstream 43, and one lower lateral skirt is located downstream 44. Thus, a single model ofaerodynamic deflector 9 may be used forwindscreen wipers 1 of the double spray bar type and of the single spray bar type. The manufacturing costs are thus reduced. - The upstream lower
lateral skirt 43 and the downstream lowerlateral skirt 44 may have different inclination angles, β1, β2, respectively. These inclination angles β1, β2 are decided depending on the efficacy of washing and the desired aerodynamic performance. The upstream lowerlateral skirt 43 and the downstream lowerlateral skirt 44 may have different lengths l1, l2, respectively. These lengths l1, l2 are decided depending on the efficacy of washing and the desired aerodynamic performance. - The invention also relates to a
method 100 for manufacturing (FIG. 4 ) anaerodynamic deflector 9. - During a
first step 101 of the method for manufacturing theaerodynamic deflector 9, a profiled element comprising theaerodynamic deflector 9, at least one lowerlateral skirt fluid circulation duct 31 is extruded. - During a
second step 102, at least one sprayingorifice 35 is pierced into at least onefluid circulation duct 31. In this step of the method, it is noted that the lowerlateral skirt fluid circulation duct 31 and prevents the latter from being pierced directly. - According to a first embodiment of the second step 102 (see
FIG. 5 ), aprojection relief 49 is produced simultaneously with the piercing of at least one sprayingorifice 35. Consequently, the sprayingorifice 35 is pierced through the lowerlateral skirt - In doing so, a hole is also pierced into the lower
lateral skirt lateral skirt fluid circulation duct 32 and prevents the latter from being pierced directly. The sprayingorifice 35 and the hole in the lowerlateral skirt same spraying direction 37. The hole thus pierced forms theprojection relief 49. The sprayingdirection 37 of the sprayingorifice 35 and of the hole is opposite to thewiper blade 5. The sprayingorifice 35 and the hole are pierced for example by way of a laser. Preferably, a plurality of sprayingorifices 35 and holes are pierced over the length of at least onefluid circulation duct 32. Piercing a singlefluid circulation duct 31 will make it possible to produce a single spray bar windscreen wiper. Piercing the twocirculation ducts 32 will make it possible to produce a double spray bar windscreen wiper. - According to a second embodiment of the second step 102 (see
FIGS. 6 a to 6 d), access to a lower part of thefluid circulation duct 32 is opened up, for example the lowerlateral skirt FIG. 6 a) by way of a mobile barrier (not shown). Opened up in this way, the lower part of thefluid circulation duct 32 is directly accessible (FIG. 6 b). Next, anorifice 35 is pierced into thefluid circulation duct 32 in a direction 37 (FIG. 6 c). Finally, the access to thefluid circulation duct 32 is barred again, for example by withdrawing the mobile barrier (FIG. 6 d). - It will thus be understood that a
windscreen wiper 1 comprising at least one lowerlateral skirt windscreen washer liquid 33 from the air streams 21, 41 flowing in the vicinity of thewindow 3 of the vehicle when the vehicle is moving. Thus, the windscreen washer liquid can reach the window and washing is improved. - In addition, the jet of
windscreen washer liquid 33 may be directed towards the lowerlateral skirt lateral skirt windscreen washer liquid 33 explodes in a plurality of directions. The windscreen washer liquid is thus distributed better over thewindow 3 and washing is further improved.
