STATE OF THE ART An automobile is conventionally equipped with windscreen wipers to ensure a washing of the windshield and to prevent the driver's vision of his environment from being disturbed. These wipers generally comprise a drive arm, performing an angular reciprocating movement, and elongate brushes, themselves carrying scraper blades made of an elastic material. These blades rub against the windshield and evacuate the water by bringing it out of the driver's field of vision. The brooms are made in the form, or, in a conventional version, articulated stirrups that hold the scraper blade in several discrete places by giving it a bend allowing it to marry the eventual curvature of the windshield, or, in a newer version called "flat blade" (for "flat blade"), a semi-rigid assembly that keeps the scraper blade along its length thanks to one or bending vertebrae to apply the broom on the bumper -brise without having to use stirrups. In both solutions, the blade is attached to the drive arm by a connector system including a connector and an adapter.

[0022] The blade 12 may further comprise end caps 22 or hooking clips of the blade 18 and the vertebra on the body 16, these end pieces 22 being located at each of the longitudinal ends of the body 16. The blade 12 comprises substantially in the middle an intermediate connector 24. An adapter 26 integral with the arm 14 is mounted on the connector 24 so as to maintain a degree of freedom in pivoting about a hinge axis Y which is a transverse axis substantially perpendicular to the longitudinal axis of the broom. 12. This degree of freedom allows a pivoting of the blade 12 vis-à-vis the arm 14 and thus allows the blade to follow the curvature of the windshield during its movements. The adapter 26 5 can be detached from the arm 14 by pressing an actuating button, here a push button 27, carried by the adapter. The arm 14 is intended to be driven by a motor to follow a reciprocating angular movement to evacuate the water and possibly other undesirable elements covering the windshield. The adapter 26 connects the blade 12 to the arm 14 and in particular to a head or end piece of the arm which can be integrally formed with the arm or attached and fixed thereto. In the case of FIG. 2, the end piece of the arm comprises or forms a yoke 28 with a substantially U-shaped cross-section, on which is slidably mounted a cap 30. The yoke 28 has an elongated shape whose axis of elongation A is generally substantially parallel to the axis of elongation or longitudinal blade 12. The yoke 28 comprises a portion 31 connecting the rest of the arm 14, for example by crimping. This portion 31 has an elongated general shape and extends along an axis B substantially parallel to the axis A and at a distance from this axis, as can be seen in FIGS. 1 and 2. Part 31 is connected to a rear end or inner end of the remainder of the yoke 28. The yoke 28 comprises two side walls 32a, 32b whose upper longitudinal edges are interconnected by an upper transverse wall 34. The walls 32a, 32b and 34 define between them a accommodating space of the adapter 26. The walls 32a, 32b comprise notches 33a, 33b, 33c, 33d through which open at their lower longitudinal edges. The notches 33a, 33b, 33c, 33d of each wall 32a, 32b are disposed longitudinally one behind the other and are here four in number. They are at longitudinal distance from each other.
[0023] The front notch 33a of each wall, located furthest forward, has a relatively small width relative to the other notches and extends substantially over the entire height of the corresponding wall 32a, 32b. The rearmost notch 33d, located furthest back, has a relatively low height relative to the other notches. Finally, the intermediate slots 33b, 33c have a relatively large width relative to the notch before 33a and extend substantially to half the height of the corresponding wall 32a, 32b. The upper wall 34 comprises two openings 38a, 38b through 10 arranged longitudinally one behind the other. The front opening 38a has a substantially circular contour and the rear opening 38b has a substantially rectangular contour.

It has an elongated shape and comprises two lateral longitudinal walls 36a, 36b whose upper longitudinal edges are connected together by an upper longitudinal wall 36c. . The front edges of the walls 36a, 36b, 36c are further interconnected by a front wall 36d of the hood. As can be seen in FIG. 2, the top wall 36c of the cover covers the top wall 34 of the yoke and its side walls 36a, 36b extend on either side of the yoke, facing the side walls 32a, 32b. The front wall 36d of the hood extends forward of the yoke and comprises a slot 40 for receiving an upper part of the deflector 20 of the blade 12, visible in FIG. 1. Finally, the upper wall 36c of the hood 30 comprises its rear end a notch 41 of generally U-shaped, which opens on the free rear edge of the wall 36c and which is directed towards the rear or the outside of the arm. The cover 30 is movable in longitudinal translation on the yoke of the arm, from a retracted position shown in Figure 2, to an advanced position. In the advanced position, the notch 41 of the cover 30 may be located at the opening 38a of the yoke and, in the retracted position, this notch 41 may be located at the opening 38b. For this, the cover 3037903 comprises WFR 2404 27 means for guiding in translation intended to cooperate with the yoke. In the example shown, each side wall 36a, 36b of the cover comprises a guide rail 42 at its lower longitudinal edge. Each rail 42 is in the form of a series of substantially co-planar longitudinal flanges 42a, 42b, 42c. The longitudinal flanges 42a, 42b, 42c of each wall 36a, 36b are arranged longitudinally one behind the other and are here three in number. They are at longitudinal distance from each other. The leading edge 42a of each wall, located furthest forward, is shown in dashed lines in FIG. 3 and better visible in FIG. 15b. The rear flange 42c, situated furthest back, has a shorter length than the flange 42a and is generally L-shaped. This flange 42c forms a hook, a first portion 42ca of which is substantially parallel to the top wall 36c and connects the side wall. 36a, 36b corresponding to a second portion 42cb 15 extending parallel to said side wall 36a, 36b and at a distance therefrom. Finally, the intermediate flange 42b has a length similar to that of the flange 42a and is shown in dashed lines in FIG. 3 and better visible in FIG. 15b. During the longitudinal sliding of the cover 30 on the yoke of the arm, the flanges 42a, 42b, 42c of the cover can slide cooperate with the free lower edges of the side walls 32a, 32b of the yoke, and the portions 42cb of the flanges 42c can cooperate by sliding with the internal faces facing these side walls 32a, 32b. As seen in FIG. 3, an end cap 44 is mounted at the free end of the yoke 28 of the arm to close the abovementioned space of the yoke in which the adapter 26 is mounted. is in the form of a block of material, preferably elastic, which comprises lateral ribs 46 intended to be engaged in the notches before 33a of the side walls 32a, 32b of the yoke, to ensure the retention of the endpiece vis-à-vis the screed. The tip 44 further comprises a slot 48 for receiving an upper part of the baffle 20 of the blade 3037903 WFR 2404 28 12, visible in Figure 1. The tip 44 is for example made by injection molding. The adapter 26, visible in FIG. 3, comprises a body configured to be mounted in the yoke and having a substantially U-shaped cross-section. It comprises two lateral walls 26a, 26b delimited longitudinally by a front longitudinal end edge. 27a and a rear longitudinal end edge 27b, and connected together by an upper wall 26c.

The side walls 26a, 26b each comprise two second projecting elements 52 of the associated side wall, in the form of pads, configured to be engaged in the intermediate slots 33b, 33c of the corresponding side wall 32a, 32b of the yoke. These second protruding members 52 may cooperate with the sliding cover 30 to secure the adapter in the yoke. In its advanced position, the flanges 42a, 42b of the cover 30 are offset longitudinally intermediate notches 33b, 33c, and are found for example respectively in front of the notch 33b and between the notches 33b, 33c.
[0024] In this position, the notches 33b, 33c are free and the adapter 26 can be housed in the yoke by translation in a direction substantially perpendicular to the upper wall 34 of the yoke (from bottom to top), until that the second projecting elements 52 engage in the intermediate slots 33b, 33c. Disassembly of the adapter is also allowed. In its retracted position, the flanges 42a, 42b of the cover 30 are found respectively under the intermediate slots 33b, 33c. In this position, the notches 33b, 33c are closed and the adapter 26 can be prevented from coming out of the yoke by pressing or abutting its second projecting elements 52 on the flanges 42a, 42b of the cover.
[0025] The side walls 26a, 26b respectively comprise two aligned through orifices 54. These orifices are located substantially in the middle of the walls 26a, 26b, between the second projecting elements 52. The orifices 54 define the substantially transverse axis Y of articulation of the connector 24 with respect to the adapter 26 and therefore of the brush 12 vis-à-vis the arm 14. The connector 24 comprises essentially two parts, a lower portion 24a crimping or attachment to the remainder of the blade 12 and an upper portion 24b to be housed between the side walls 26a, 26b of the adapter. This upper portion 24b comprises a through orifice 56 intended to be aligned on the Y axis. The orifices 54, 56 are intended to receive a cylindrical rod defining the hinge axis Y. In a variant, one of the members Adapter 26 and connector 24 could comprise cylindrical journals centered on the Y axis and intended to be engaged by resilient snapping in the orifice or orifices of the other of these members. Figures 4a to 11 illustrate a first aspect of the invention, Figures 4a to 7 showing a first embodiment of this aspect and Figures 8 to 11 showing an alternative embodiment. According to this first aspect of the invention, the first projecting element 150, 250 above projecting on the upper wall 126c, 226c of the adapter 126, 226 comprises at least one lower surface 160a, 260a, which is directed towards the wall upper 126c, 226c, and which is configured to cooperate by support and / or sliding with the yoke 28 or with the cover 30, to retain the adapter vis-à-vis the arm. In the case of FIGS. 4a to 7, the first projecting element 150 comprises a lower surface 160a, which is oriented towards said upper wall 126c, and which is configured to cooperate by bearing and / or sliding with the yoke to retain the adapter vis-à-vis the screed.
[0026] In the example shown, the first protruding element 150 has a generally staggered or L-shaped shape. It comprises a substantially parallelepipedal step or lower portion 150a, similar to the first protruding element 50 of FIG. directly to the upper wall of the adapter and carries a step or upper portion 150b offset longitudinally rearwardly relative to the lower portion 150a. The lower portion 150a has a shape and dimensions determined to be engaged with little or no play in the opening 38b of the yoke. This lower portion 150a defines an upper surface 150aa parallel to the upper wall 126c of the adapter and which is oriented on the opposite side to this upper wall, so that it is intended to cooperate by sliding with the inner face of the upper wall. 36c of the hood 30, as can be appreciated in Figures 6a and 6b which show respectively the hood in the advanced and retracted positions. The upper portion 150b has a generally parallelepipedal shape whose front end is rounded. It forms a rear longitudinal tab 160 whose lower surface defines the lower surface 160a 20 above. The tab is longitudinally offset from the lower portion 150a and is arranged to extend longitudinally beyond the rear longitudinal end edge 127b. This surface 160a is parallel to the upper wall 126c of the adapter and intended to cooperate by sliding with the upper face of the upper wall 34 of the yoke, as can be seen in FIG. 5 in particular. It is noted in Figures 6b and 7 that the notch 41 has a shape complementary to the front end of the upper portion 150b. The adapter 126 is here formed in one piece and has a median longitudinal plane P of symmetry parallel to the side walls 126a, 126b and passing substantially in the middle of the upper wall 126c. This plane P 3037903 WFR 2404 31 passes through the first projecting element 150 substantially in its middle (FIG. 4a). The cooperation of the first protruding element 150 and in particular of its lug 160 with the yoke 28 of the arm makes it possible to hold the adapter 126 towards the arm. This first projecting element 150, forming the adapter retaining means, is here situated in the vicinity of the rear end of the adapter 126. It thus makes it possible to ensure retention of the rear end of the adapter. with respect to the yoke, and can make it possible to do without a part of the second elements projecting from the adapter. The adapter 126 of FIGS. 4a to 7 is indeed devoid of such second rear projecting elements and comprises only two second projecting elements 152 at the front, which are situated in the vicinity of the front end of the housing. adapter and which are on the one hand intended to be engaged in the intermediate notches 33b of the yoke when the cover is in the advanced position on the yoke, and secondly to cooperate with the aforementioned front edges 42a of the cover when this last is in the retracted position on the yoke (Figure 7). Mounting the adapter relative to the yoke is accomplished by inserting the upper portion 150b into the hole of the yoke and then tilting the adapter around the front edge defining the hole. Then the adapter is pushed enough so that the tab 260 can then be folded against the upper wall 34 of the yoke, by switching the adapter in reverse. The lower portion 150a of the first protruding member is then fitted into the clevis hole before it is locked in position by sliding the cover 30. In the case of FIGS. 8 to 11, the first projecting element 250 comprises a lower surface. 260a, which is oriented towards said upper wall 226c of the adapter 226, and which is configured to cooperate by bearing and / or sliding with the cover 30 to retain the adapter with respect to the yoke 28 and the hood .
[0027] In the example shown, the first projecting element 250 has a generally U-shape. It comprises a substantially parallelepipedal lower portion 250a, similar to the first projecting element 50 of FIG. 3, a substantially cylindrical intermediate portion 250b. and an upper portion 250c defining a tab 260 oriented longitudinally forwards. The lower portion 250a has a shape and dimensions determined to be engaged with low play or without play in the opening 38b of the yoke. This portion 250a defines an upper surface 250aa parallel to the upper wall 226c of the adapter and intended to cooperate by sliding with the inner face of the top wall 36c of the cover 30, as can be appreciated in FIGS. 10a and 10b which respectively show the hood in advanced and retracted positions. The intermediate portion 250b is intended to be engaged in the notch 41 of the cover 30 and to conform to its substantially play-free shape. The upper portion 250c has a parallelepipedal overall shape whose rounded rear end and the angles of its front end. are beveled. The tab 260 defines the lower surface 260a above. This surface 260a is parallel to the upper surface 250aa and facing the latter, at a determined distance to form a receiving zone of the cover 30. This upper surface 260a is intended to cooperate by sliding with the upper face of the upper wall. 36c of the hood 30, as can be seen in FIG. 11 in particular.
[0028] The adapter 226 is here formed in one piece and has a median longitudinal plane P of symmetry parallel to the side walls 226a, 226b and passing substantially in the middle of the upper wall 226c. This plane P passes through the first projecting element 250 substantially in the middle (FIG. 8b).
[0029] The cooperation of the first projecting element 250 and in particular of its tab 260 with the sliding cover of the arm makes it possible to hold the adapter 226 opposite the arm. This first protruding element 250 forming a retaining means is here located in the vicinity of the rear end of the adapter 226. It thus makes it possible to ensure that the rear end of the adapter is retained with respect to the clevis, and may allow to pass a part of the second elements projecting from the adapter. The adapter 226 of FIGS. 8 to 11 is indeed devoid of second rear projecting elements and comprises only two second protruding elements at the front front 252, which are situated in the vicinity of the front end of the adapter and which are on the one hand intended to be engaged in the intermediate slots 33b of the yoke when the cover is in the advanced position on the yoke, and secondly to cooperate with the aforementioned flanges 42a of the cover when the latter is in the retracted position on the yoke (Figure 11). It is understood that mounting the adapter in the yoke in this variant of the first aspect of the invention is simplified by the fact that the upper leg portion 250c 260 does not extend beyond the longitudinal end edge. back of the adapter. A simple translation operation makes it possible to pass the first element protruding through the hole of the yoke to provide a receiving zone to the sliding cowl 20 in its retracted position. Figures 12 to 15b illustrate a second aspect of the invention, Figures 12 to 13b showing a first embodiment of this aspect and Figures 14 to 15b showing an alternative embodiment.

[0031] In the case of FIGS. 12 to 13b, the adapter 326 comprises front tabs 362 which are intended to be engaged in recesses 364 of the end piece 44 mounted at the free front end of the arm clevis. The mounting of the nozzle 44 takes place as explained above, by engaging its ribs 46 in the notches before 33a of the yoke 28. The front tabs 362 extend longitudinally forwards from the side walls 326a, 326b. They are substantially parallel. They each have a parallelepipedic general shape. They extend over a major part of the height of the side walls 326a, 326b.
[0032] The recesses 364 are located at the rear end of the nozzle 44 and communicate with the inner space of the yoke 28 when the nozzle 44 is mounted at the free end of the yoke. Each of the recesses 364 includes a lower surface 364a and an upper surface 364b, which can cooperate in abutment with the lower and upper ends of the front tabs 362, respectively. As in the previous example, the adapter 326 may comprise only two second projecting elements 352 on the outer faces of its side walls 326a, 326b. In the case of FIGS. 14 to 15b, the adapter 426 comprises a rear lug 462 which is intended to be engaged in the yoke and to cooperate by bearing and / or abutment with the rear flanges 42c of the cover 30. The lug 462 extends longitudinally rearwardly from the upper wall 426c and the side walls 426a, 426b. It has a generally U-shaped shape and is formed by the longitudinal rear extension of the walls 426a, 426b, 426c. It extends over the entire width of the upper wall 326c and over part of the height of the side walls 426a, 426b. The lower free longitudinal edges 462a of the tab 462 are intended to cooperate by bearing with the free upper ends of the portions 42cb of the rear flanges 42c, as can be seen in FIG. 15b.
[0033] As in the previous example, the adapter 426 may comprise only two second protruding members 452 on the outer faces of its side walls 426a, 426b. It is understood that in both cases of the second aspect of the invention, the at least one tab 362, 462 and the second projecting element 352, 452 are arranged longitudinally on either side of the hinge axis Y of the adapter as defined by the alignment of the through orifices respectively in each side wall of the adapter, it being understood that the axis of articulation of the adapter could be defined by the alignment 10 of male means if the associated connector was equipped with female means. This longitudinal arrangement on either side of the hinge axis allows a stable mounting, it is obtained with a tab in the vicinity of the rear end of the adapter and a second element projecting in the vicinity of the front end, as illustrated or in an inverted arrangement where the tab is in the vicinity of the front end of the adapter and the second element protruding near the rear end. In the two last cases mentioned above, the adapter 326, 426 is formed in one piece and has a median longitudinal plane P of symmetry.

This housing has a generally U-shaped shape. The front longitudinal end wall 773 of the fairing forms a bottom wall of the housing, so that it forms a stop wall at the insertion of the end of the yoke into the housing. housing 774.
[0044] The lateral walls 726a, 726b of the body comprise hinge means 754 configured to receive first complementary means 756 of the connector 724 and associated with first elastically deformable resilient detent means 776 configured to cooperate with these complementary means 756 when their reception by the hinge means 754. The lateral walls 726a, 726b of the body furthermore comprise second resiliently elastically detachable elastic detent means 778 configured to cooperate with second means 33d complementary to said yoke 28.
[0045] In the example shown, the side walls 726a, 726b respectively comprise two orifices 754 which are aligned and form the aforementioned articulation means. The side walls 726a, 726b respectively comprise two longitudinal slots 780, which extend from the orifices 754 on the opposite side to said fairing 772. Each of the side walls 726a, 726b comprises a lower longitudinal tab whose upper part defines a peripheral portion of the corresponding orifice 754. This lower tab is at least partly elastically deformable so as to form said first elastic locking means 776.
[0046] The lower leg has a free longitudinal end having a sliding ramp 776a configured to cooperate with the complementary means 756 of the connector, which are here a journal (Figure 21). Each of said sidewalls 726a, 726b includes an upper lug 782, a lower portion of which defines a peripheral portion of the corresponding aperture 754. The upper lug 782 is at least partially resiliently deformable and forms said second resilient snap-fastening means 778. The upper lug 782 is generally L-shaped and comprises two substantially rectilinear portions, a first portion 782a extending therethrough. corresponding orifice 754 on the side opposite to the fairing 772 and is connected on the opposite side to the fairing to a second portion 782b which extends downwards. The second portions 782b of the upper legs 782 respectively comprise two transverse fingers 782c extending in opposite directions and configured to be engaged by resilient snapping in the complementary means of the yoke 28, which are here the rear notches 33d. The fingers 782c extend in the same longitudinal plane passing substantially through the aforementioned lower tabs. The adapter 726 is formed in one piece. The adapter 726 of Figures 19a-21 can be mounted as follows. As shown in FIGS. 20a and 20b, the yoke 28 is mounted on the body of the adapter 726 by longitudinal translation from the rear to the front, until its free front end is engaged in the housing 774 above. of the adapter and that the fingers 782c engage snap and elastic return outward in the rear notches 33d of the yoke 28 (Figure 20c). During this translation, the fingers 782c run along the free end edge of the side walls. When the fingers arrive near the rear notch, they first contact a boss 784 formed upstream of the rear notch, and the fingers then skirt the boss by elastic deformation of the upper tabs 782. When the boss 784 is past, the tabs tend to return to their original position and the fingers are housed in the notch, to be retained in longitudinal recess by the shoulder that forms the boss. In this position, the adapter 726 is secured to the yoke 28. The adapter is then mounted on the connector 724 by inserting the pins 756 of the connector 724 in the holes of the adapter. The journals 756 are engaged in the slots 780 and rest on the ramps 776a. A longitudinal translation 10 of the connector towards the adapter causes the sliding of the trunnions 756 on the ramps 776a and a deformation of the lower lugs of the adapter, this translation being continued until the trunnions engage by elastic snap in the orifices 754 of the adapter. The journals cooperate with these holes to allow rotational movements 15 of the adapter vis-à-vis the connector, and vice versa, about the aforementioned Y axis. Figures 22 and 23 illustrate a fifth aspect of the invention, wherein the adapter 826 comprises an elongate body 20 configured to be secured to the substantially U-sectioned yoke 28 of a wiper arm. The body has a substantially U-shaped section and comprises two lateral longitudinal walls 826a, 826b connected together by an upper longitudinal wall 826c.
[0047] The top wall 826c has at least one projecting element 850a, 850b, 850c configured to be housed in at least one aperture 38a, 38b passing through the clevis 28. In the example shown, the adapter 826 comprises three protruding elements 850a, 850b, 850c, each of which is intended to be engaged in a hole 38a, 38b of the yoke, only one of these openings 38b being visible in FIG. 23 and being intended to receive two of the projecting elements 850b, 850c. The hole 38a of the yoke 3037903 WFR 2404 43 receive the other projecting element 850a is hidden by the cover 30 mounted on the yoke 28, in the retracted position in Figure 23. The projecting elements 850a, 850b, 850c are arranged one behind the other in the longitudinal direction. The front member 850a has a generally cylindrical shape. The intermediate element 850b has a generally parallelepipedal shape and the rear element 850c has a hook or L shape. This rear element 850c comprises a first lower part substantially perpendicular to the upper wall 826c and extending upwards from this last. Its upper end is connected to an upper portion such as a flange 851, substantially parallel to the top wall 826c, and extending rearwardly. The intermediate element 850b comprises a front surface 850b1 oriented longitudinally forwards and intended to cooperate by bearing with a complementary surface facing the rear of the orifice 38b of the upper wall 34 of the yoke 28. The element rear 850c comprises a rear surface 850c1 oriented longitudinally rearwardly and intended to cooperate by bearing with a complementary surface oriented towards the front of the orifice 38b, as can be seen in FIG. 23. This rear surface 850c1 is here carried by the lower part of the element 850c. It is also seen in Figure 23 that the upper flange 851 is configured to cooperate by bearing with the upper face 34 of the yoke 28 to retain the adapter vis-à-vis the yoke. The surfaces 850b1, 850c1 are configured to be held tight against the complementary surfaces of the port 38b to retain the adapter 826 from the clevis 28. Notably, it is anticipated that the rear projecting element 850c is a flexible tab, which can be articulated about an axis defined by the junction of the tab and the upper wall 826c of the adapter. The projecting elements are thus defined by a centering means associated with an orifice of the yoke, here the front element 850a associated with the orifice 38a, and by a fixing means associated with the other orifice 3037903 WFR 2404 44 orifice and formed by the remaining two projecting elements. At least one of these two remaining elements is a flexible tab. It may be provided in a non-illustrated variant that the two projecting elements forming the fixing means consist of two flexible projecting elements articulated respectively about an axis formed by the junction line of the upper wall with said projecting element. corresponding, and disposed opposite so that the contact surfaces carried respectively by the projecting elements are oriented opposite to each other.
[0048] The body of the adapter 826 is here devoid of stud protruding from its side walls 826a, 826b. The adapter 826 is here formed in one piece. Figures 24a and 26 illustrate a sixth aspect of the invention, in which the adapter 926 comprises an elongated body configured to be secured to the substantially U-sectioned yoke 28 of a wiper arm. The body has a substantially U-shaped cross-section and has two lateral longitudinal walls 926a, 926b connected together by an upper longitudinal wall 926c. The adapter is configured to be engaged in the yoke by translation in a direction substantially perpendicular to the top wall 926c, from bottom to top (arrow F in Figure 25). The side walls 926a, 926b comprise lugs 984 that are elastically deformable in the transverse direction and configured to cooperate by elastic snap-fastening with means 42a, 42b complementary to the yoke 28 and / or a member mounted on the yoke, such as the hood. 30. The tabs 984 include retaining teeth 985, 986 configured to cooperate with the yoke 28 and / or the hood 30.
[0049] In the example shown, each side wall 926a, 926b comprises two elastically deformable lugs 98 each comprising two retaining teeth 985, 986, which are respectively lower and upper. Each of the tabs 984 has a general orientation perpendicular to the top wall 926c. Each lug 984 is delimited by two parallel and through slots 987 formed on the corresponding side wall 926a, 926b and opening on the free bottom edge of this side wall. The legs of the same side wall are at a distance from each other. They extend substantially over 60 to 100% of the height of the side walls, or even preferably from 70 to 90% of this height. Each lug 984 includes a lower tooth 985. This lower tooth 985 forms a rim that extends transversely outwardly of the body. It is substantially perpendicular to the general orientation of the tab 984 and therefore substantially parallel to the upper wall 926c.
[0050] Each tab 984 includes an upper tooth 986, which forms a stud that extends transversely outwardly of the body. This tooth defines at its lower end a retaining surface 986a, substantially parallel to the lower tooth 985, and at its upper end an outer ramp 986b intended to cooperate by sliding with the abovementioned complementary means 42a, 42b of the yoke 28 or the 30. The teeth 985, 986 of each lug 984 are spaced from each other and define between them a receiving space of the means 42a, 42b. This space is more accurately defined by the surface 986a of the upper tooth and the rim or the lower tooth 985. The adapter 926 is formed in one piece. In the example shown, the lugs 984 are configured to cooperate by resilient snap-fastening with the cover 30, and in particular with the rails or flanges 42a, 42b for slidingly guiding the cover 30.
[0051] When the hood 30 is in the retracted position on the yoke 28, the adapter 926 can be mounted in the yoke by positioning it under the yoke, as shown in FIG. 25. The adapter is then moved in one direction. substantially perpendicular to the upper wall, in the direction of the arrow F, until the flanges 42a, 42b of the cover 30 bear on the ramps 986b of the upper teeth 986 of the legs 984. The translation of the adapter is continued so that the flanges 42a, 42b slide on the ramps, which causes the deformation of the tabs 984 by transverse bending towards the inside of the body, the ends or lower teeth 985 of the tabs 984 carried by a side wall approaching ends or lower teeth 985 of the tabs 984 carried by the other side wall. The translation of the adapter is continued until the flanges 42a, 42b engage between the teeth 985, 986 of the tabs, by elastic return of the tabs in their rest position. In this position, the surfaces 986a of the upper teeth 984 can cooperate by pressing with the flanges 42a, 42b to prevent a downward movement of the adapter with respect to the yoke, i.e. a displacement opposite the direction of the arrow F. The lower teeth 985 of the tabs can cooperate with these flanges to limit the upward movement of the adapter vis-à-vis the yoke. To release the adapter from the yoke, it is conceivable to deform the lugs 984 by bending them inwards, manually or by means of a tool, for example by resting on the lower teeth 985 of the lugs. Alternatively, it is possible to move the cover 30 to its advanced position so that its flanges 42a, 42b do not interfere with the output of the adapter of the yoke.
[0052] Figures 27 and 28 illustrate a seventh aspect of the invention, wherein the adapter 1026 comprises an elongated body configured to be secured to the substantially U-sectioned yoke 28 of a wiper arm.
[0053] The body has a substantially U-shaped cross section and has two sidewalls 1026a, 1026b interconnected by an upper wall 1026c. The upper wall 1026c comprises a first projecting element 1050 configured to extend at least partly in a hole 38b passing through the yoke 28. This first projecting element 1050 is here similar to that of the variant of FIGS. 8a to 12 but could 5 naturally be different. At least one of the walls of the body of the adapter comprises an elastically deformable tongue 1087 configured to bear on an inner face of the yoke 28, in order to eliminate a clearance between the adapter and this inner face.
[0054] In the example shown, the adapter 1026 comprises a tongue 1087 of this type, which is here located on the upper wall 1026c of its body. The tongue 1087 is located near a longitudinal end of the body, here before, and the first protruding element 1050 is located at an opposite longitudinal end, therefore a rear end of the body. The tongue 1087 is flexible and has a material end with the associated wall of the adapter body and a free end 1087a configured to be movable between an unstressed position where its free end projects from the plane of the top wall. , outside the body (Figure 27), and a folded and constrained position in which it extends substantially in the plane of the upper wall (Figure 18). It is located in a recess or port 1088 of the body. In the folded position, it is housed at least partly in this orifice and, in the projecting position, it extends upwards from the upper wall 1026c. The tongue 1087 is able to cooperate by bearing with the inner face of the upper wall 34 of the yoke 28. The body of the adapter has a plane of symmetry P parallel to the side walls 1026a, 1026b and passing substantially in the middle of the wall superior 1026c. This plane of symmetry P substantially passes through its middle tongue 1087.
[0055] In the example shown, the body of the adapter 1026 comprises on an external lateral face of each of its side walls 1026a, 1026b, a single second protruding element 1052 configured to be engaged in the notch 33b (FIG. not visible) of the coping 28.
[0056] 5 The adapter is formed in one piece. It is retained in the yoke 28 by the first projecting element 1050, as explained above in connection with the variant of FIGS. 8a to 12. The tongue 1087 cooperates with the yoke 28 to limit the vibrations of the adapter in the clevis, in the direction in which the tongue protrudes from the associated wall. Fixing the adapter in the yoke, in particular by means of the first projecting element cooperating with the hole of the yoke, and by the locking of the adapter by the guide rails of the sliding cover as mentioned above, may generate vibrations due in particular to the mounting clearance of the first element protruding into the orifice. It will be understood that the position of the tongue on one or the other of the walls of the adapter makes it possible to limit the vibrations in a particular direction substantially perpendicular to the associated wall. In a non-illustrated variant, at least two tabs may be provided, one on the upper wall and another on at least one of the side walls, to limit the vibrations of the adapter relative to the yoke in several directions. In each of these cases, it is advantageous to have the tab or tongues disposed at a longitudinal end of the adapter opposite the longitudinal end on which the first protruding element is arranged, for the best absorption of the elements. vibrations generated by the set of mounting of the first element protruding with the screed. Figures 29a to 30 illustrate an eighth aspect of the invention, wherein the adapter 1126 comprises an elongated body configured to be secured to the substantially U-sectioned yoke 28 of a wiper arm.
[0057] The body has a substantially U-shaped cross-section and has two side walls 1126a, 1126b connected together by an upper wall 1126c. The top wall 1126c has a first projecting member 1150 configured to extend at least partially into the hole 38b of the yoke 28. The adapter 1126 further comprises at least one clip 1188 configured to be attached and secured to the first protruding element 1150 to lock the adapter 1126 to the yoke 28.
[0058] In the example shown, the first protruding element 1150 is generally T-shaped and comprises a first wall 1150a substantially parallel to the top wall 1126c and a second wall 1150b connecting the first wall 1150a to the top wall 1126c, and substantially perpendicular to the top wall 1126c. The second wall 1150b 15 extends substantially in a median longitudinal plane P of symmetry of the body. The clip 1188 has a generally U-shaped shape and comprises two longitudinal fingers 1190 substantially parallel and connected by one of their longitudinal ends to a common base 1191.
[0059] The fingers 1190 are elastically deformable by bending towards and / or away from each other. They include retaining hooks 1192 at their opposite ends to the base 1191. The hooks 1192 are oriented in the transverse direction towards each other. The body of the adapter 1126 is here devoid of projecting elements 25 on its side walls 1126a, 1126b. The adapter 1126 is here formed in one piece. As indicated in the foregoing, the cover 30 is configured to be displaceable in translation between a first so-called advanced position where it is remote from the orifice 38b and a second so-called retracted position where it is close to this orifice, or even covers it. partly and part of the first protruding element. The sliding cover 30 here comprises a notch 41 for receiving a front portion of the first projecting element 1150 as well as a front portion of the clip 1188, namely the ends of the fingers 1190 carrying the hooks 1192. Advantageously, in the retracted position of the cover 30, the peripheral edge of the notch 41 of the cover 5 30 is able to cooperate by abutment with the free ends of the fingers 1190 which surround the first projecting element 1150, so as to prevent a separation fingers and disassembly of the clip 1188 of the element 1150 when the cover is held in this position. The invention thus proposes a mounting method in which the adapter 1126 is mounted in the yoke 28 of the arm, so that the first protruding element 1150 passes through the orifice 38b of the yoke 28. staple 1188 around the first projecting element, in particular by sliding the clip against the upper wall of the yoke. The fingers are elastically deformed away from each other, the hooks 1192 coming into contact with the second wall 1150b during the translation of the clip. The fingers take the original shape when the hooks have exceeded the second wall 1150b, these hooks forming axial retention means abutting against the second wall. The adapter is thus locked against the yoke, the first wall 1150a abutting vertically against the fingers so that the first protruding member can not escape through the hole. The hood is then moved along the yoke, from its advanced position to its retracted position and from locking the staple 1188, the peripheral edge of the notch forcing the hooks to move towards one another to secure the staple position around the first protruding member. Figures 31 to 35 illustrate a ninth aspect of the invention, in which the adapter 1226 has an elongated shape and is configured to be secured to the cover 30, here movable, disposed at the end of the wiper arm 30 .
[0060] The adapter comprises a front fairing 1294 and a rear body 1295 which has a substantially U-shaped cross section and has two side walls 1226a, 1226b connected together by an upper wall 1226c.
[0061] The fairing 1294 has a front wall 1294a which is configured to extend forwardly of the rear body 1295 so as to define with the body 1295 a longitudinal space 1296 for receiving a front portion of the hood 30. The fairing 1294a a generally U-shaped opening rearwardly and the middle portion of which is formed by the front wall 1294a. The lateral portions of the U are formed by lateral walls 1294b which extend rearwardly from the front wall 1294a. The side walls 1294b are intended to extend on each side of the hood and to cover it, at least laterally, in Part (Fig. 33d), when the arm, and the hood it is carrying, and the adapter are assembled The fairing 1294 includes an upper opening 1294c for mounting the cover 30 in space. The width of the fairing, i.e. the dimension between the side walls, is greater than the width of the rear body, so that a transverse space 1296a is provided on each side of the rear body between it and the fairing. The side walls 1226a of the body 1295 respectively comprise two orifices 1254 aligned, which define the hinge axis Y above. The side walls each further comprise a projecting lug 1297 of the corresponding side wall. Each lug 1297 is located under the orifice 1254 of the corresponding lateral wall 1226a, 1226b, at the junction between this wall and a transverse web connecting the lateral wall 1226a, 1226b to the lower end of the fairing side wall 1294b. 1294 nearest. It is understood that the transverse web and the lug define the dimension of the transverse space left laterally between the rear body and the fairing. Each lug 1297 has a parallelepipedal general shape and comprises a rearward facing face 1297a and a laterally facing outward facing side 1297b. The face 1297a is a bearing surface of a complementary means of the cover, which is here the front end of the intermediate flange 42b of the cover. The intermediate flanges 42b of the cover are thus intended to bear on the rear faces 1297a of the lugs 1297 of the adapter, in the mounted position of the cover in the adapter (FIGS. 33d to 35). The face 1297b is a bearing face of a corresponding side wall 36a, 36b of the cover 30. The cover is thus intended to laterally grip the adapter 1226 by pressing its side walls 36a, 36b on the faces 1297b of the lugs 1297. The lateral walls 1226a, 1226b of the body also comprise elastically deformable elastic snap means configured to cooperate with complementary means of the cover 30. Each side wall 1226a of the body comprises a longitudinal tab 1298 elastically deformable and forming said means elastic snap. Each lug 1298 has a general L shape and comprises two substantially rectilinear portions, a first portion 1298a of which extends rearwardly in the extension of the rear body, here from the side walls, and is connected to a second portion 1298b which extends down.
[0062] The first portions 1298a each comprise a notch 1298aa made by cutting the lower face of the first portion 1298a in the direct vicinity of the second portion 1298b. This notch forms a means of receiving a complementary means carried by the hood, namely the rear flanges 42c and more particularly the second portions 42cb forming a hook of these rear flanges. The first portions 1298a of the tabs are connected to the side walls by a zone of lesser section facilitating the articulation of the first portions about an axis formed by the junction line of the side walls and the tab. The legs are thus articulated to debate transversely.
[0063] The second portions 1298b of the tabs respectively comprise two transverse fingers 1299 extending in opposite directions and configured to be accessible when the arm and the adapter are secured. The fingers 1299 extend in the same longitudinal plane. Each finger 1299 has a generally parallelepipedal shape and comprises a front face 1299a against which can come to bear the rear flange 42c of the hood. The fingers thus participate in maintaining the longitudinal position of the cover thus intended to be clamped between the rear faces 1297a of the lugs 1297 and the front faces 1299a of the fingers 1299 of the adapter, in addition to the cooperation of the rear edges with the notches of the legs . These fingers form actuation means accessible by the user to force the tabs to deform elastically and allow the disengagement of the complementary means of the cover, and thus allow the disassembly of the adapter relative to the arm. (Figures 33d to 35). The adapter 1226 is formed in one piece.
[0064] Figures 33a to 33d show steps of mounting the hood and the arm carrying the hood in the adapter. The arm and the hood are arranged as shown in FIG. 33a, the hood being positioned above the adapter and being ready to be inserted into the space 1296 by passing through the opening 1294c of the fairing 1294. The hood 30 is then moved in longitudinal translation until insertion into the space 1296 and contact of the front end wall of the hood with the front wall 1294a of the fairing (FIG. 33b). The hood is then moved with the arm by rotating it about a transverse axis located substantially at the front wall of the fairing. This pivoting can be facilitated by the sliding of the front wall 36d of the cover 30 on the outer face of the front wall 1294a of the fairing 1294. The pivoting is continued with the side walls of the cover which engage in the transverse spaces 1296a, arranged on either side of the rear body 1295, which contributes to the correct transverse positioning of the arm and the hood so that the complementary means of the cap cooperate with the elastic latching means carried by the adapter. The pivoting forces the legs 1298 in transverse elastic deformation away from each other to allow the hooks 42cb to pass through the rear edges 42c of the cover 30. When the hooks take place opposite the notches 1298aa, the tabs return to their original position in the axis of the side walls 5 of the adapter and the hooks are facing, possibly in support of the front faces 1299a of the fingers 1299. The cover is engaged in this manner between the faces 1297a, 1299a above and is maintained constrained longitudinally, especially between these faces (Figures 33c and 33d). 10
