Description

[0001] This application is a divisional application of application number 201811241951.2, filed on October 22, 2018, entitled "Adapter for a motor vehicle windscreen wiper and wiper comprising the same". TECHNICAL FIELD

[0002] The present invention particularly relates to an adapter for a wiper, in particular for a wiper of a motor vehicle.

[0003] The present invention also relates to an assembly comprising a wiper arm and an adapter according to the invention.

[0004] The present invention also relates to a motor vehicle wiper comprising a wiper blade and a connection assembly comprising an adapter according to the invention. BACKGROUND

[0005] Motor vehicles are generally equipped with wipers, in particular for cleaning the outer surface of the windscreen, so as to prevent the driver's view of the surrounding environment from being disturbed.

[0006] The wipers generally comprise a drive arm, which performs a forward and backward, in particular angular, movement, and a longitudinal and elongated wiper, which carries a wiper blade or blade rubber made of an elastic material, such as rubber or elastomer material.

[0007] The wiper blade rubs against the outer surface of the windscreen and removes water, taking it out of the driver's view.

[0008] In a traditional form, the wiper is made in the form of a hinged fender, which holds the wiper blade at several longitudinally distributed discrete points, to which a curvature is applied, so that it can conform to the curvature or curve that the windscreen can have.

[0009] In a newer form, known as "flat blade" design, the wiper is made in the form of a semi-rigid assembly, which supports the wiper blade along its entire length using one or more backing strips, which bend the wiper blade and allow the wiper and blade to be pressed against the windscreen without the need to use a fender.

[0010] In both designs, the wiper is connected to the drive arm by a connection system, which comprises a connector and an adapter, which are complementary to each other.

[0011] The connector is a component that is fixed to the wiper and is generally fixed directly to the wiper blade or flat blade, while the adapter is fixed to the connector.

[0012] The adapter is an intermediate part which allows the connector to be connected and fixed to the drive arm. It is usually shaped so that it can be engaged in the yoke-shaped end piece or head of the drive arm having an inverted U-shaped cross-section.

[0013] Each of these two parts (connector and adapter) comprises articulation means designed to cooperate with complementary means belonging to the other part in order to define at least one transverse articulation axis of the two parts relative to each other, which is also the articulation axis of the wiper relative to the drive arm.

[0014] According to the known art, one of the parts, such as the connector, usually comprises a substantially cylindrical physical axis which defines the articulation axis and is received in a complementary-shaped housing belonging to the other part.

[0015] The adapter usually comprises an elongated body shaped to be engaged in the front free terminal end piece of the drive arm so that this body extends at least partially between the two substantially parallel lateral walls of this end piece.

[0016] The adapter allows the wiper to be fitted onto a specific type of end piece. In the case of the above-mentioned end piece having an inverted U-shaped cross-section, there are many different variants.

[0017] A known wiper arm is one in which the end piece carries a cap mounted with the ability to slide in longitudinal translation. The cap is mounted with the ability to slide longitudinally between a front first or forward position and a rear second or rearward position. In addition to the aesthetic advantages it offers, this type of cap can perform other functions.

[0018] Various examples of designs of adapters and related assemblies are shown in document FR A1 3 037 896.

[0019] Figure 12 of this document shows a design in which the adapter comprises a longitudinally elongated body delimited by two vertical longitudinal lateral walls which are laterally opposite and connected together by a horizontal upper wall, and which is shaped to be mounted in a complementary yoke belonging to the inverted U-shaped cross-section of the wiper arm, and in which, at its front longitudinal end, the body of the adapter comprises at least one retention tab which extends longitudinally forward and which is shaped to cooperate with the yoke or with a member or part carried by the yoke in order to retain the adapter relative to the yoke.

[0109] In the remainder of the specification, elements with the same structure or similar function will be indicated by the same reference numerals.

[0110] In the remainder of the specification, the longitudinal, vertical, and lateral orientations shown in the “L, V, T” trihedral reference system in the figure will be used non-limitingly. A horizontal plane, extending longitudinally and laterally, is also defined.

[0111] Therefore, in the instruction manual, the longitudinal or transverse designation refers to the orientation of the wiper or drive arm.

[0112] The longitudinal direction corresponds to the main axis of the wiper or drive arm, which extends from back to front according to the orientation of the axis L of the trihedral reference system L, V, T.

[0113] The directions inside, outside, internal or external can refer to a component as a whole, and for example, refer to the inside or outside of that component.

[0114] Figure 1 A windshield wiper 10 is depicted, which specifically includes a wiper 12 and a drive arm 14 (also called a wiper arm) for driving the wiper 12.

[0115] The wiper 12 here is a flat blade type and includes a longitudinal body 16, a wiper blade 18 typically made of rubber or elastomeric material, and at least one backing strip (not shown) that hardens the blade and helps to press it against the outer surface of a vehicle window, such as the vehicle's curved windshield (not shown).

[0116] The longitudinal body 16 of the wiper 12 includes an upper aerodynamic deflector 20 for improving the operation of the wiping system. The purpose of the deflector is to improve the pressure of the wiper 12 on the windshield and thus improve the aerodynamic performance of the windshield wiper 10.

[0117] The wiper 12 also includes end parts 22 or attachment clips for attaching the wiper 18 and backing strip to the longitudinal body 16, the end parts 22 being located at each of the two opposite front and rear longitudinal ends of the longitudinal body 16.

[0118] The drive arm 14 is designed to be driven by a motor so that it follows a back-and-forth motion, such as an angular reciprocating motion, allowing the wiper blade 18 to remove water and any other potentially undesirable elements covering the outer surface of the windshield.

[0119] Substantially in the middle along its length, the wiper 12 comprises a connection assembly comprising a middle connector 24 and an adapter 26, 1026.

[0120] Two embodiments of the adapter 26, 1026 are depicted. A first embodiment is depicted in Figures 3 to 7 A second embodiment of the adapter is depicted in Figures 10 to 22

[0121] Each adapter 26, 1026 is a part made in one piece by molding and presents a design symmetry with respect to a longitudinal and vertical median plane.

[0122] The adapter 26, 1026 fixed to the arm 14 is mounted on the connector 24 in such a way as to allow a degree of freedom of pivoting about a hinged transverse axis Y, which is substantially vertical to the longitudinal axis of the wiper 12.

[0123] This degree of freedom allows the wiper 12 to pivot in both directions with respect to the driving arm 14, thus allowing the wiper 12 to conform to the curvature or curve of the windscreen as it moves.

[0124] The adapter 26, 1026 provides the connection between the wiper 12 and the driving arm 14, and in particular the head or front longitudinal terminal end piece of the driving arm 14, which can be formed integrally with the driving arm or alternatively added and attached thereto.

[0125] In Figures 1 to 3 and 8, the end piece of the driving arm is a front free end portion in the form of a yoke 28, having a substantially inverted U-shaped cross section.

[0126] The cap 30 is mounted with the ability to slide over the free end yoke 28 and to cover the yoke 28.

[0127] The yoke 28 has an elongated shape, which extends along a longitudinal axis A, which is generally substantially parallel to the entire longitudinal axis of the wiper 12.

[0128] The yoke 28 comprises a connection portion 31 for connection to the rest of the driving arm 14, to which it is attached, for example by crimping.

[0129] The portion 31 has an elongated overall shape and extends along a longitudinal axis B, which is substantially parallel to the axis A and is laterally or transversely offset with respect to the axis A, as can be seen in Figure 1 and Figure 2 The portion 31 is connected to the rear end of the yoke 28.

[0130] ​The yoke 28 comprises two longitudinally oriented vertical lateral walls 32a, 32b, the upper longitudinal edges of which are connected together by a longitudinally oriented upper transverse wall 34. The walls 32a, 32b and 34 between them define an internal space which accommodates the adapter 26.

[0131] The lateral walls 32a, 32b comprise a series of through notches 33a, 33b, 33c, 33d which are vertically downwardly open and open to their lower longitudinal edges 37a, 37b.

[0132] In this case, the number of notches 33a, 33b, 33c, 33d in each wall 32a, 32b is four and they are spaced apart from each other and arranged longitudinally in front of each other.

[0133] The front notch 33a in each lateral wall 32a, 32b, which is located longitudinally most forward, has a longitudinal width which is relatively small compared to the other notches and which extends vertically substantially over the entire height of the respective lateral wall 32a, 32b.

[0134] The rear notch 33d, which is located longitudinally most rearward towards the rear, has a height which is small compared to the height of the other notches.

[0135] The intermediate notches 33b, 33c between the front notch 33a and the rear notch 33d have a longitudinal width which is relatively large compared to the front notch 33a and which extends vertically substantially as far as an intermediate position of the height of the respective lateral wall 32a, 32b.

[0136] The upper wall 34 comprises two front and rear longitudinally arranged through openings 38a, 38b. The front opening 38a has a substantially circular profile and the rear opening 38b has a substantially rectangular profile.

[0137] In a vertical and transverse planar cross-section, the cap 30 has a substantially inverted U-shaped cross-section.

[0138] The cap 30 comprises two longitudinally and vertically oriented lateral walls 36a, 36b, the upper longitudinal edges of which are connected together by a longitudinally and horizontally oriented upper wall 36c.

[0139] The front vertical edges of the lateral walls 36a, 36b and the upper wall 36c are also connected together by a substantially vertically and transversely oriented front wall 36d of the cap.

[0140] When the cap 30 is in the assembled position, its upper wall 36c covers the upper wall 34 of the yoke 28 and its lateral walls 36a, 36b extend longitudinally one on each side of the yoke, facing the outer surfaces of the lateral walls 32a, 32b (see Figure 2 ).

[0141] The front wall 36d of the cap extends forwardly from the yoke 28 and comprises a vertical slot 40 which can receive opposite portions of the upper part of the deflector 20 of the wiper 12, as Figure 1 visible in

[0142] At its rear end, the upper wall 36c of the cap 30 comprises a notch 41 having an overall shape C which opens longitudinally into the free rear transverse edge of the upper wall 36c.

[0143] The cap 30 is able to translate longitudinally on the yoke 28 of the drive arm 14 between a rear position, shown in Figure 2 , and a forward position longitudinally offset relative to the rear position.

[0144] In the forward position, the notch 41 of the cap 30 can be in line with the front opening 38a of the yoke, while in the rear position, the notch 41 can be in line with the rear opening 38b.

[0145] To achieve this, the cap 30 comprises longitudinal translation guide means for cooperating with the yoke 28.

[0146] Each lateral wall 36a, 36b of the cap 30 comprises a guide rail arranged at its lower longitudinal edge. Each guide rail takes the form of a series of substantially coplanar longitudinal flanges 42a, 42b, 42c which extend transversely inwards.

[0147] The three longitudinal flanges 42a, 42b, 42c of each wall 36a, 36b are arranged longitudinally in front of and behind one another and are spaced apart from one another.

[0148] The flanges 42a, 42b, 42c of the cap 30 can slide in cooperation with the free lower edges of the lateral walls 32a, 32b of the yoke 28 of the drive arm 14 when the cap 30 slides longitudinally along the yoke 28.

[0149] As shown in Figure 3 , 4 and 15 to 22, a front longitudinal end piece 44 is mounted at the front free end of the yoke 28 of the drive arm 14 to close the yoke space in which the elongated rear body 25, 1025 of the adapter 26, 1026 is housed.

[0150] The end piece 44 takes the form of a block of material, preferably of an elastomeric material, comprising two opposite lateral securing ribs 46 each formed in relief on a vertical lateral face and extending vertically as a whole. The end piece 44 is manufactured, for example, by injection molding.

[0151] Each securing rib 46 is intended to engage in the front notch 33a of the relevant lateral wall 32a, 32b of the yoke 28 in order to secure and retain the end piece 44 on the yoke 28.

[0152] The end piece 44 also comprises a vertical slot 48 able to receive the opposite part of the upper part of the deflector 20 of the wiper 12.

[0153] In Figures 3 to 7 In the first embodiment illustrated, the adapter 26 comprises an elongated rear body 25 shaped to be mounted in the yoke 28.

[0154] In cross section in a transverse vertical plane, the adapter is substantially inverted U-shaped. It comprises two longitudinal and vertical lateral walls 26a, 26b longitudinally delimited towards the front by front longitudinal end vertical edges 27a, 27b and towards the rear by rear longitudinal end vertical edges 127a, 127b.

[0155] The two lateral walls 26a, 26b are connected together by a horizontal upper wall 26c.

[0156] The lateral walls 26a, 26b comprise respectively a transversely aligned orifice 54 and a trunnion 53. These elements 53 and 54 are substantially longitudinally located in the middle of the lateral walls 26a, 26b of the adapter 26.

[0157] In a known manner, the elements 53 and 54 define the general transverse axis Y of the pivotal articulation of the connector 24 relative to the adapter 26 and therefore of the wiper 12 relative to the drive arm 14.

[0158] The connector 24 substantially comprises a lower part 24a for being crimped or fixed to the rest of the wiper 12 and an upper part 24b for being housed between the inner faces of the lateral walls 26a, 26b of the adapter 26.

[0159] The upper part 24b comprises means 56 complementary to the elements 53 and 54 for being aligned with the axis Y.

[0160] As an alternative, in the adapter 26 and the connector 24, one can comprise a cylindrical trunnion centered on the axis Y and intended to be fastened by an elastic clip into one or more complementary orifices of the other of these parts.

[0161] At its front longitudinal end, the body 25 of the adapter 26 comprises here, non limitatively, two retaining tabs 62a, 62b each extending longitudinally forward in the continuation of the relevant lateral wall 26a, 26b of the body 25 of the adapter 26.

[0162] Each retaining tab 62a, 62b is shaped to cooperate with the yoke 28 or with a part carried by the yoke 28.

[0163] Here, the retention tabs 62a and 62b, which are intended to engage in complementary recesses of the end piece 44 mounted at the front free end of the yoke 28 of the arm, also allow the positioning of the adapter 26.

[0164] The retention tabs 62a and 62b are substantially parallel, each have a general cuboid shape and extend vertically over a substantial height of the lateral walls 26a and 26b.

[0165] By an alternative not shown, the body 25 of the adapter 26 can comprise a single retention tab which extends horizontally and longitudinally forward in continuation of the horizontal upper wall 26c of the body 25 of the adapter 26 and is shaped to cooperate with the yoke 28 or with a piece carried by the yoke 28.

[0166] By non-limiting example, at its rear longitudinal end, the body 25 of the adapter 26 comprises here two retention tabs 63a, 63b, each extending longitudinally rearward in continuation of the associated lateral wall 26a, 26b of the body 25 of the adapter 26.

[0167] Each retention tab 63a, 63b is shaped to cooperate with the yoke 28 or with a piece carried by the yoke 28.

[0168] The retention tabs 63a and 63b are substantially parallel, each have a general cuboid shape and extend vertically over a lower part of the height of the lateral walls 26a and 26b.

[0169] Near its rear longitudinal end, the body 25 of the adapter 26 comprises a locking tab 100 configured to be received through a hole in the yoke 28, which is in this case a rear opening 38b of generally rectangular profile in the upper wall 34 of the yoke 28.

[0170] The rear opening or hole 38b is delimited longitudinally toward the rear by a rear transverse edge 39b with which the locking tab 100 cooperates, as will be explained later.

[0171] As can be seen in particular in Figure 6 , the locking tab 100 extends vertically in continuation of the outer surface 29 of the upper wall 26c of the body 25 of the adapter 26, above the horizontal plane of the body 25 of the adapter 26.

[0172] The retention tabs 62a, 62b and the locking tab 100 are arranged longitudinally on each side of the axis Y-Y of the pivotal articulation of the adapter 26 relative to the connector 24.

[0173] The locking tab 100 is positioned longitudinally between the axis Y-Y of the pivotal articulation of the adapter 26 relative to the connector 24 and the retention tabs 63a, 63b.

[0174] The locking tab 100 is configured to be received through the opening 38b in the yoke 28 and comprises a free upper portion 102 shaped as a hook.

[0175] As can be seen in particular in the perspective view of Figure 5A and 5B , the hook-shaped portion 102 is a solid portion which is laterally centered with respect to the body 25 of the adapter 26.

[0176] The hook-shaped portion 102 comprises a vertical central branch 104 which is extended by a locking branch 106 which extends longitudinally rearward.

[0177] The locking branch 106 is vertically downwardly delimited by a lower surface 108 shaped as a small plane, which in this example is oriented horizontally as a whole, which is configured to cooperate with an opposite portion of the outer surface of the yoke 28.

[0178] In the mounted and locked position, the lower surface 108 bears against a portion 35 of the outer surface of the upper wall 34 of the yoke 28 which is directly posterior to the posterior lateral edge 39b of the rear opening 38b.

[0179] The vertical branch 104 of the hook-shaped portion 102 of the locking tab 100 comprises a posterior surface 110 for contact with the posterior lateral edge 39b of the rear opening 38b of the yoke 28.

[0180] In this case, the posterior contact surface 110 is, by way of non-limiting example, a planar surface which extends in a vertical plane as a whole and which is able to contact the posterior lateral edge 39b of the rear opening 38b of the yoke 28 which is a rectilinear lateral edge.

[0181] The upper portion of the locking branch 106 of the hook-shaped portion 102 comprises a profiled surface portion 112 forming a cam which is able to cooperate with the posterior lateral edge 39b of the rear opening 38b of the yoke 28 in order to move the hook 102 longitudinally forward with respect to the body 25 of the adapter 26.

[0182] In this case, the profiled surface 112 is part of an arc of a convex cylinder.

[0183] The locking tab 100 is connected to the body 25 of the adapter 26 by a vertical connection which is elastically deformable in order to allow the longitudinal movement of the posterior contact surface 110 in both directions with respect to the body 25 of the adapter 26.

[0184] In the embodiment illustrated in Figures 3 to 7 , the vertical connection which connects the locking tab 100 to the body 25 of the adapter 26 comprises two laterally opposite lateral connection branches 114a, 114b.

[0185] Each connecting branch 114a, 114b extends vertically as a whole, in this case sloping upwards and forwards from the bottom.

[0186] Each connecting branch 114a, 114b extends upward from the upper surfaces 65a, 65b of the associated retaining protrusions 63a, 63b, near the latter's rear end.

[0187] The upper ends of the two connecting branches 114a and 114b are connected to each other by an upper crossbeam 116, which extends horizontally and includes a horizontal upper surface 118. The vertical central branch 104 of the hook-shaped portion 102 of the locking tab extends vertically upward from this horizontal upper surface in general.

[0188] The vertical connecting portion formed by the two connecting branches 114a and 114b extends vertically below the horizontal plane of the outer surface 29 of the upper wall 26c of the body 25 of the adapter 26.

[0189] The vertical connection formed by the two connecting branches 114a and 114b is elastically deformable so as to pivot about the transverse axis ZZ relative to the body 25 of the adapter 26, which is adjacent to the lower end of each of the two connecting branches 114a and 114b.

[0190] The lateral pivot axis ZZ is vertically positioned below the horizontal plane of the outer surface 29 of the upper wall 26c of the body 25 of the adapter 26.

[0191] To facilitate the elastic deformation of the vertical connection and the pivoting motion around the transverse axis ZZ, recesses 120a and 120b are formed in the material portion of the relevant lateral wall of the body 25 connecting the retaining tabs 63a and 63b to the adapter 26, at the front of the lower end of the connecting branches 114a and 114b.

[0192] The lower connecting part has the ability to elastically deform and pivot about the transverse axis ZZ. Figure 6 As shown, the locking tab 100, which has its lower connecting portion, is depicted in its undeformed free state by solid lines, and in its deformed and pivoted state in the counterclockwise direction indicated by arrow F by dashed lines 100', 114'.

[0193] exist Figure 4 The diagram schematically and partially illustrates one step of installing and assembling the adapter 26 onto the yoke 28.

[0194] As can be seen, after the retaining tabs 62a and 62b have engaged in the complementary recesses of the end member 44 mounted at the front free end of the yoke 28 of the arm, the adapter 26 is brought into place. Figure 4the part of the convex profiled surface 112 comes into contact with the rear transverse edge 39b of the rear opening 38b of the yoke 28.

[0195] By continuing the relative movement of the adapter 26 with respect to the yoke under load so as to introduce the locking tab 100 through the rear opening 38b, a cam effect occurs between the surface 112 and the edge 39b and causes the fixing tab to pivot more or less about the transverse axis Z-Z.

[0196] Once the lower surface 108 has passed the outer surface portion 35, the locking tab 100 elastically returns to its almost undeformed free state and the rear contact surface 110 comes into contact with the rear transverse edge 39b of the rear opening 38b of the yoke 28, bearing against the latter with a slight elastic contact and load in the entire longitudinal direction.

[0197] When it is desired to detach the wiper, the hook-forming upper part 102 projects above the outer surface of the upper wall 34 of the yoke 28.

[0198] It thus constitutes an unlocking "button" on which the user can act by moving it longitudinally forward against the elasticity of the vertical connecting parts 114a, 114b.

[0199] In order to make this action easier, the convex profiled surface can be ribbed or provided with any suitable particular surface finish.

[0200] It is desirable to avoid any risk of accidental separation between the wiper arm and the wiper, and thus of loss of the wiper, even under heavy load.

[0201] This heavy load can occur in particular when the windscreen wiper is used on a glass surface covered with ice or having a fairly thick layer of snow.

[0202] To this end, in order to avoid any risk of breakage of the locking tab 100, and in particular of its hook-forming free upper part 102, under load, the locking branch 106 is able to elastically deform with respect to the vertical branch 104 under the action of the force applied to it.

[0203] As can be seen in Figure 7 and by virtue of this capacity for elastic deformation, the locking branch 106 is in particular able to pivot with respect to the vertical branch 104 about the transverse axis X-X.

[0204] The transverse axis X-X is here adjacent to the rear end edge of the lower surface 108 and is substantially adjacent to the vertical branch 104.

[0205] To make the locking branch 106 more easily elastically deformable and to perform its pivoting movement about the transverse axis X-X, the hook-shaped portion 102 comprises a recess 122 formed in the connection zone between the vertical branch 104 and the locking branch 106.

[0206] The recess 122 is here formed in the continuation of the lower face 108 of the locking branch 106.

[0207] The recess 122 is a transversely oriented groove.

[0208] As can be seen from the large scale in Figure 7 the lower face 108 of the locking branch 106 is connected to the groove 122 by a transverse corner 124 able to cooperate with the opposite portion 35 of the outer face of the upper wall 34 of the yoke 28.

[0209] The ability of the locking branch to elastically deform without breaking and to pivot about the transverse axis X-X is illustrated in Figure 7 where the locking branch 106 is depicted in solid line in its free state of non-deformation and in dashed line 106', 108', 112' in a state in which it is deformed and pivoted in the counterclockwise direction.

[0210] The adapter 1026 according to the second embodiment is substantially similar in form and general design to the adapter 26 of the first embodiment.

[0211] The adapter 1026 comprises an elongated rear body 1025 shaped to be mounted in the yoke 28.

[0212] In cross-section on a transverse vertical plane, the adapter 1026 substantially takes the shape of an inverted U. It comprises two vertical and longitudinal lateral walls 1026a, 1026b delimited longitudinally towards the front by front longitudinal end vertical edges 1027a, 1027b and delimited longitudinally towards the rear by rear longitudinal end vertical edges 1127a, 1127b.

[0213] The two lateral walls 1026a, 1026b are connected together by a horizontal upper wall 1026c.

[0214] As in the first embodiment, the body 1025 of the adapter 1026 comprises a locking tab 100 configured to be received through a hole in the yoke 28, said hole being in this case the rear opening 38b of the generally rectangular profile of the upper wall 34 of the yoke 28.

[0215] The locking tab 100 is connected to the body 1025 of the adapter 1026 by a vertical branch 104 able to elastically deform to allow the rear contact surface 110 to move longitudinally in both directions relative to the body 1025 of the adapter 1026.

[0216] At its front longitudinal end, the body 1025 of the adapter 1026 further comprises two retaining tabs 1062a, 1062b, each extending longitudinally forward in a continuation of the relevant lateral wall 1026a, 1026b of the body 1025 of the adapter 1026.

[0217] The retaining tabs 1062a and 1062b are substantially parallel. They each have the overall shape of a cuboid.

[0218] Each retaining tab 1062a, 1062b comprises a lower chamfer 1126a, 1126b formed on its lower edge.

[0219] Each retaining tab 1062a, 1062b is shaped to cooperate with the yoke 28 or with a component carried by the yoke 28. The chamfers 1126a, 1126b make it easier to insert the adapter 1026 into the yoke 28 or into a component carried by the yoke 28, such as the end component 44 described here by way of non-limiting example.

[0220] The retaining tabs 1062a, 1062b provide vertical retention of the adapter 1026.

[0221] By way of non-limiting example, at its rear longitudinal end, the body 1025 of the adapter 1026 comprises two retaining tabs 1063a, 1063b, each extending longitudinally rearward in a continuation of the relevant lateral wall 1026a, 1026b of the body 1025 of the adapter 1026.

[0222] Each retaining tab 1063a, 1063b is shaped to cooperate with the yoke 28 or with a component carried by the yoke 28.

[0223] The retaining tabs 1063a and 1063b are substantially parallel. They are connected by a transverse and horizontal rear transverse member 1128.

[0224] Each retaining tab 1063a, 1063b has the overall shape of a cuboid and extends vertically over a lower part of the height of the relevant vertical lateral wall 1026a and 1026b.

[0225] The retaining tabs 1063a, 1063b have a rear end that abuts against the yoke 28 or against a component carried by the yoke 28.

[0226] The rear transverse member 1128 extends horizontally between the two retaining tabs 1063a, 1063b. It connects the rear ends of the retaining tabs 1063a, 1063b.

[0227] The width (measured in the longitudinal direction) of the rear cross member 1128 corresponds to more than half the length of the retaining tabs 1063a, 1063b.

[0228] The length of the retaining tabs 1063a, 1063b is calculated so that the rear end of each retaining tab 1063a, 1063b abuts the yoke 28 or a component carried by the yoke 28.

[0229] The retaining tabs 1063a, 1063b thus serve to retain the adapter in the rear longitudinal direction. If the wipers are pulled longitudinally rearward relative to the yoke 28, they significantly make it possible to avoid damage to the locking tabs 100.

[0230] The rear cross member 1128 makes it possible to increase the stiffness of the rear end of the adapter 1026, in particular of the retaining tabs 1063a, 1063b.

[0231] By way of non-limiting example, at its front longitudinal end, the body 1025 of the adapter 1026 comprises two front stop members 1029a, 1029b of convexly curved or curled profile, each of these end stop members defining a convexly curved stop surface 1130a, 1130b for longitudinally positioning the adapter 1026 relative to the yoke 28 or to a component such as the end piece 44 carried by the yoke 28.

[0232] Each stop member 1029a, 1029b extends in a curve vertically downward in the continuation of the relevant lateral wall 1026a, 1026b of the body 1025 of the adapter 1026.

[0233] Each curved stop member 1029a, 1029b laterally abuts the outer surface of the associated retaining tab 1062a, 1062b.

[0234] The longitudinal thickness of each stop member 1029a, 1029b decreases vertically from top to bottom so as to present a convexly curved profile facing forward (see Figure 12).

[0235] The convex stop surfaces 1130a, 1130b thus have an upper transverse edge that is longitudinally forwardly offset relative to the lower transverse edge of the convex stop surfaces 1130a, 1130b.

[0236] The convexly curved stop members 1029a, 1029b allow the adapter to be longitudinally positioned on the yoke 28 or on a component carried by the yoke 28, for example the end piece 44.

[0237] When assembling the adapter 1026 associated with the end piece 44 and the yoke 28, the convex stop surfaces 1130a, 1130b of the curved stop 1029a, 1029b bear longitudinally against a portion of the end piece 44 of the yoke 28 or facing it (see Figure 21 ). Thus, the curved profile of the curved stop 1029a, 1029b serves as an assembly guide, allowing the adapter 1026 to be longitudinally pre-positioned in the yoke 28.

[0238] This pre-positioning occurs gradually and the convex surface facilitates the relative pivoting movement of the adapter with respect to the yoke during assembly.

[0239] By way of non-limiting example, each of the lateral walls 1026a, 1026b comprises an elastically deformable tab in the transverse direction, called an elastic tab 1132a, 1132b.

[0240] The elastic tabs 1132a, 1132b are located on the front or front portion of the lateral wall 1026a, 1026b. They extend over approximately 20% to 50% of the length of the lateral wall, or even preferably 25% to 35% of this length.

[0241] Each elastic tab 1132a, 1132b has an overall longitudinal orientation parallel to the upper wall 1026c, which means a horizontal orientation.

[0242] Each elastic tab 1132a, 1132b is delimited by two horizontal parallel grooves 1136a, 1136b and one front vertical vertical groove 1138a, 1138b connecting the two parallel grooves 1136a, 1136b. These grooves are formed in the corresponding lateral wall 1026a, 1026b and pass through this wall.

[0243] In an alternative form not shown, it is also conceivable for the elastic tab to have a vertical overall orientation orthogonal to the upper wall 1026c.

[0244] In this case, the front free end of each elastic tab 1132a, 1132b comprises a longitudinal retention lug or tooth 1134a, 1134b configured to cooperate with the yoke 28 and / or with a component carried by the yoke 28 and / or the cap 30.

[0245] The retention lug 1134a, 1134b projects laterally outward relative to the plane of the associated elastic tab 1132a, 1132b.

[0246] The lug has a triangular cam profile with an upper ramp 1133a, 1133b, a lower ramp 1135a, 1135b, a front face 1137a, 1137b and a rear face 1139a, 1139b.

[0247] The front face 1137a, 1137b of each retaining lug 1134a, 1134b bears longitudinally on the yoke 28. The retaining lugs 1134a, 1134b thus allow the adapter 1026 to be fixed in a forward longitudinal direction relative to the yoke 28.

[0248] The length of the upper ramp 1133a, 1133b is greater than the length of the lower ramp 1135a, 1135b.

[0249] The upper ramp 1133a, 1133b of the retaining lug 1134a, 1134b allows each elastic tab 1132a, 1132b to retract to pass over the longitudinal flange 42a located at the front of the cap 30 when the adapter 1026 is assembled in the yoke 28.

[0250] The lower ramp 1135a, 1135b of the retaining lug 1134a, 1134b allows each elastic tab 1132a, 1132b to retract to pass over the longitudinal flange 42a located at the front of the cap 30 when the adapter 1026 is disassembled.

[0251] Due to their elasticity and due to the triangular profile of their retaining lugs 1134a, 1134b, the elastic tabs 1132a, 1132b do not contribute to the vertical retention of the adapter 1026 relative to the yoke and / or the cap 30. In contrast, the elastic tabs 1132a, 1132b do contribute to the final longitudinal positioning of the adapter 1026.

[0252] In another alternative form, not shown, the profile of the lugs 1134a, 1134b can be that of a trapezoid with an upper ramp and a lower ramp. The operation of the elastic tabs is then essentially similar.

[0253] The lateral walls 1026a, 1026b comprise projecting uprights 1140a, 1140b, 1142a, 1142b configured to cooperate with the yoke 28 and / or the cap 30. The uprights 1140a, 1140b, 1142a, 1142b project laterally outward and each have a cuboid overall shape.

[0254] In the second embodiment, by way of non-limiting example, each lateral wall 1026a, 1026b comprises two front uprights 1140a, 1140b and two rear uprights 1142a, 1142b.

[0255] The front uprights 1140a, 1140b are located at the front of the lateral wall 1026a, 1026b. They are configured to cooperate with the cap 30 and to bear against the front end of the notch 42a of the cap 30.

[0256] The front posts 1140a, 1140b ensure that the cap 30 is slid back in the closed position relative to the yoke 28 during the installation of the adapter 1026.

[0257] This is because when the cap 30 is in the forwardly slid open position, the flange 42b of the cap 30 is located below the position for receiving the front posts 1140a, 1140b, thus preventing the adapter 1026 from being installed and assembled in the yoke 28.

[0258] The rear posts 1142a, 1142b are located on the rear of the lateral walls 1026a, 1026b. In the illustrated embodiment, the rear posts 1142a, 1142b protrude laterally from the retaining tabs 1063a, 1063b.

[0259] The rear posts 1142a, 1142b are configured to cooperate with the yoke 28, in particular with the rear notches 33d. They interface the front edge of the relevant rear notch 33d in such a way as to provide longitudinal retention of the adapter 1026 relative to the yoke 28 in the rearward direction.

[0260] Thus, the retaining lugs 1134a, 1134b of the elastic tabs 1132a, 1132b and the front posts 1140a, 1140b provide a double "fixing" of the adapter 1026 relative to the yoke longitudinally forward, in particular under significant load.

[0261] The rear posts 1142a, 1142b also press slightly upward against the horizontal upper edge of the rear notches 33d.

[0262] The bottom of the lateral walls 1026a, 1026b comprises a bottom 1143a, 1143b having a convex rounded profile of circular arc or rounded shape.

[0263] In a second embodiment, this rounded bottom 1143a, 1143b is formed on the outside with an additional lateral thickness, thus increasing the rigidity of the lower part of the lateral walls 1026a, 1026b.

[0264] This additional thickness makes it possible for the adapter 1026 to better withstand the torsion and deformation that can be experienced under heavy load, which can occur on a glass surface covered with ice or with a layer of snow when using a windscreen wiper.

[0265] In particular, once the adapter 1026 is installed on the wiper 12, the lower part of the adapter 1026 is exposed to the open air and can be attacked by the external environment, in particular under adverse weather conditions such as snow or ice.

[0266] The bottom 1143a, 1143b of the adapter 1026 also comprises rounded protrusions 1144a, 1144b.

[0267] As Figure 20 visible in the

[0268] The adapter 1026 here comprises at least one picking zone 1146 and 1148 for positioning a suction cup so that the machine can pick up the adapter 1026 when it is mounted on the wiper 12 in the factory.

[0269] For example, the rear cross member 1128 has a horizontal rear extension 1146 corresponding to a first picking zone. The rear extension 1146 comprises a rounded rear edge which extends the rear cross member 1128 and makes it easier to position a picker suction cup (not depicted).

[0270] The horizontal upper wall 1026c also has a horizontal upper extension 1148 with a rounded rear edge corresponding to a second picking zone.

[0271] In an alternative form of embodiment not shown, the upper wall of the body of the adapter can comprise an elastically deformable tongue configured to bear against the inner surface of the upper wall of the yoke so as to eliminate any play that can exist between the adapter and this inner surface.

[0272] Such a play compensation tongue is for example located near the front longitudinal end of the body and the locking tab 100 is located at the opposite rear longitudinal end of the body.

[0273] The mounting and assembly of the adapter 1026 in the yoke 28 are similar to those described with reference to the first embodiment.

[0274] The adapter 1026 is mounted and can only be mounted when the cap 30 is in the rearwardly slid closed position.

[0275] First, the retaining tabs 1062a, 1062b engage in complementary recesses in the end piece 44 mounted at the front free end of the yoke 28 of the arm. The presence of the chamfers 1126a, 1126b facilitates their engagement.

[0276] The adapter 1026 is then brought into Figure 4 the position shown by pivoting it upward.

[0277] Pivoting of the adapter 1026 is made easier by the curved stops 1029a, 1029b which bear longitudinally against the end piece 44.

[0278] During pivoting or tilting, the retaining lugs 1134a, 1134b of the elastic tabs 1132a, 1132b retract due to the upper slopes 1133a, 1133b, so that they can pass over the longitudinal flange 42a located at the front of the cap 30.

[0279] The front surfaces 1137a, 1137b of the retaining lugs 1134a, 1134b abut against the yoke 28, providing longitudinal retention of the adapter 1026 in the forward direction.

[0280] Next, the front uprights 1140a, 1140b pass over the flange 42a of the cap 30, ensuring that the latter is indeed in the closed position.

[0281] Finally, the rear uprights 1142a, 1142b are inserted into the rear notches 33d and abut against the front edges of the rear notches 33d, in order to provide longitudinal retention of the adapter 1026 in the rearward direction.

[0282] The adapter is then in the position shown in particular in Figures 16 to 22 Fig. 6.

[0283] In this position, a portion of the convex profile surface 112 is in contact with the rear transverse edge 39b of the rear opening 38b of the yoke 28.

[0284] The locking tab 100 is then locked in the rear opening 38b of the yoke 28, as in the first embodiment.

[0285] To detach the adapter 1026 of the second embodiment from the wiper 12, the procedure is similar to that in which the adapter 26 of the first embodiment is detached.
