Abstract
Description
[0001] This application is a divisional application of application number 202211135946.X entitled "Adapter for a motor vehicle windshield wiper and wiper including the adapter", filed on October 22, 2018. Technical Field
[0002] The present invention relates in particular to an adapter for a wiper, especially an adapter for a wiper for a motor vehicle.
[0003] The present invention also relates to an assembly comprising a wiping arm and an adapter according to the invention.
[0004] The present invention also relates to a motor vehicle wiper, which includes a wiper blade and a connection assembly including an adapter according to the present invention. Background Technology
[0005] Motor vehicles are typically equipped with wipers, especially for cleaning the outer surface of the windshield, to prevent the driver's view of the surrounding environment from being obstructed.
[0006] Wipers typically include: a drive arm that performs forward and backward, especially angular, movements; and a longitudinally elongated wiper that carries a wiper blade or wiper rubber made of an elastic material such as rubber or an elastomer.
[0007] The wiper blades rub the outer surface of the windshield and remove water, taking it out of the driver's view.
[0008] In its traditional form, the wiper is manufactured as an articulated front crossbar that holds the wiper blade at several longitudinally distributed discrete points, applying curvature to it so that it can conform to the curvature or curve that the windshield may have.
[0009] In an updated form known as the "flat wiper" design, the wiper is manufactured as a semi-rigid assembly that uses one or more backing strips to support the wiper blade along its entire length. These backing strips allow the wiper blade to bend and allow the wiper and blade to press against the windshield without the need for a front crossbar.
[0010] In both designs, the wiper is connected to the drive arm via a connection system that includes a connector and complementary adapters.
[0011] The connector is a component that is fixed to the wiper and is usually directly fixed to the wiper blade or flat blade, while the adapter is fixed to the connector.
[0012] The adapter is an intermediate component that allows the connector to be attached and secured to the drive arm. It is typically shaped so that it can engage in the yoke-shaped end part or head of the drive arm with an inverted U-shaped cross-section.
[0013] Each of these two components (connector and adapter) includes a hinge mechanism designed to cooperate with a complementary mechanism belonging to the other component to define at least one lateral hinge axis between the two components relative to each other, which is also the hinge axis of the wiper relative to the drive arm.
[0014] According to known technology, one of the components, such as a connector, typically includes a generally cylindrical physical axis that defines a hinge axis and is received in a housing of a complementary shape belonging to another component.
[0015] The adapter typically includes an elongated body shaped to engage in the front free end portion of the drive arm, such that the body extends at least partially between two substantially parallel lateral walls of the end portion.
[0016] The adapter allows the wiper to be fitted onto a specific type of end part. In the case of the end part with the inverted U-shaped cross-section described above, many different variations exist.
[0017] One known type of wiper arm is one in which a central portion carries a cap that is mounted to have the ability to slide longitudinally. The cap is mounted to have the ability to slide longitudinally between a first forward position or a forward position and a second rear position or a rear position. In addition to the aesthetic advantages it provides, this type of cap can perform other functions.
[0018] The document FR A1 3 037 896 illustrates various examples of adapter and related component designs.
[0019] The file Figure 12 A design is shown in which the adapter includes a longitudinally elongated body defined by two vertical longitudinal lateral walls laterally opposed to each other and connected together by a horizontal upper wall, and is shaped to be mounted in a complementary yoke with an inverted U-shaped cross-section belonging to a wiper arm, and wherein, at its front longitudinal end, the body of the adapter includes at least one retaining tab extending longitudinally forward and shaped to cooperate with the yoke or a member or component 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] Along its length substantially in the middle, the wiper 12 includes a connecting assembly comprising a middle connector 24 and adapters 26, 1026.
[0120] Two embodiments of adapters 26 and 1026 are depicted. The first embodiment is... Figures 3 to 7 The second embodiment of the adapter is described in [the text]. Figures 10 to 22 It was described in the text.
[0121] Each adapter 26, 1026 is a component made by molding as a single piece and exhibits design symmetry relative to the longitudinal and vertical midplanes.
[0122] The adapter 26, 1026, fixed to the arm 14, is mounted on the connector 24 in such a way that it allows for a degree of freedom of pivoting about the hinge lateral axis Y, which is substantially perpendicular to the longitudinal axis of the wiper 12.
[0123] This degree of freedom allows the wiper 12 to pivot in two directions relative to the drive arm 14, thereby allowing the wiper 12 to conform to the curvature or curve of the windshield as it moves.
[0124] Adapters 26, 1026 provide a connection between the wiper 12 and the drive arm 14, and in particular the head or front longitudinal end part of the drive arm 14, which may be integrally formed with the drive arm or alternatively added to and attached thereto.
[0125] exist Figures 1 to 3 In 8, the end component of the drive arm is the 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 to have the ability to slide on and cover the yoke 28 at the free end.
[0127] The yoke 28 has an elongated shape that extends along a longitudinal axis A, which is generally parallel to the entire longitudinal axis of the wiper 12.
[0128] The yoke 28 includes a connection portion 31 for connecting to the rest of the drive arm 14, the yoke being attached to the connection portion, for example by crimping.
[0129] Part 31 has an elongated overall shape and extends along a longitudinal axis B that is substantially parallel to axis A and is offset laterally or transversely relative to axis A, such as Figure 1 and Figure 2As can be seen in the image, part 31 is connected to the rear end of the yoke 28.
[0130] The yoke 28 includes two longitudinally oriented vertical lateral walls 32a and 32b, whose longitudinal upper edges are connected together by a longitudinally oriented upper transverse wall 34. The walls 32a, 32b and 34 between them define an internal space for accommodating the adapter 26.
[0131] The lateral walls 32a, 32b include a series of through recesses 33a, 33b, 33c, 33d that open vertically downwards and open to their lower longitudinal edges 37a, 37b.
[0132] In this case, the number of notches 33a, 33b, 33c, and 33d in each wall 32a and 32b is four, and they are spaced apart from each other and arranged longitudinally back and forth.
[0133] The front recess 33a in each of the lateral walls 32a, 32b, which is located at the front longitudinally, has a longitudinal width that is relatively small compared to the other recesses and extends vertically over the entire height of the respective lateral wall 32a, 32b.
[0134] The rear notch 33d, which is positioned furthest longitudinally towards the rear, has a height that is smaller than the height of the other notches.
[0135] The intermediate recesses 33b and 33c between the front recess 33a and the rear recess 33d have a relatively larger longitudinal width compared to the front recess 33a, and these longitudinal widths extend vertically and substantially to the middle of the height of the corresponding lateral walls 32a and 32b.
[0136] The upper wall 34 includes two through openings 38a and 38b arranged longitudinally front to back. The front opening 38a has a generally circular profile, and the rear opening 38b has a generally rectangular profile.
[0137] In the cross-sections of the vertical and horizontal planes, the cap 30 has a cross-section that is essentially inverted U-shaped.
[0138] The cap 30 includes two longitudinal and vertical lateral walls 36a and 36b, whose longitudinal upper edges are connected together by a longitudinal and horizontal upper wall 36c.
[0139] The front vertical edges of the lateral walls 36a, 36b and the upper wall 36c are also connected by the front wall 36d, which is generally vertically and laterally oriented as described in 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 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 forward from the yoke 28 and includes a vertical groove 40 that receives the upper portion of the deflector 20 of the wiper 12, such as Figure 1 It is visible in the text.
[0142] At its rear end, the upper wall 36c of the cap 30 includes a notch 41 having an integral shape C, which opens longitudinally into the free rear transverse edge of the upper wall 36c.
[0143] Cap 30 is able to Figure 2 Between the rear position shown and the forward position that is longitudinally offset relative to the rear position, there is a longitudinal translation on the yoke 28 of the drive arm 14.
[0144] In the forward position, the notch 41 of the cap 30 can be aligned with the front opening 38a of the yoke, while in the rear position, the notch 41 can be aligned with the rear opening 38b.
[0145] To achieve this, the cap 30 includes a longitudinal translation guide for cooperating with the yoke 28.
[0146] Each side wall 36a, 36b of the cap 30 includes a guide rail disposed at its lower longitudinal edge. Each guide rail takes the form of a series of substantially coplanar longitudinal flanges 42a, 42b, 42c that extend laterally inward.
[0147] The three longitudinal flanges 42a, 42b, 42c of each wall 36a, 36b are arranged longitudinally back and forth and spaced apart from each other.
[0148] When the cap 30 slides longitudinally along the yoke 28 of the drive arm 14, the flanges 42a, 42b, and 42c of the cap 30 can slide cooperatively with the free lower edges of the lateral walls 32a and 32b of the yoke 28.
[0149] like Figure 3 As shown in 4 and 15 to 22, the front longitudinal end component 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 accommodated.
[0150] The end component 44 is in the form of a block of material, preferably an elastic material, and includes two opposing lateral fixing ribs 46, each lateral fixing rib 46 being formed as a protrusion on a vertical lateral surface and extending vertically overall. The end component 44 is manufactured, for example, by injection molding.
[0151] Each retaining rib 46 is used to engage in the front recess 33a of the corresponding lateral walls 32a, 32b of the yoke 28 in order to secure and retain the end member 44 on the yoke 28.
[0152] The end component 44 also includes a vertical groove 48 that can receive the upper portion of the deflector 20 of the wiper 12.
[0153] exist Figures 3 to 7 In the first embodiment shown, the adapter 26 includes an elongated rear body 25, which is shaped to be mounted in a yoke 28.
[0154] In the cross-section of the transverse and vertical planes, the adapter is essentially inverted U-shaped. It includes two longitudinal and vertical lateral walls 26a, 26b, which are longitudinally defined towards the front by the front longitudinal end vertical edges 27a, 27b and towards the rear by the rear longitudinal end vertical edges 127a, 127b.
[0155] The two lateral walls 26a and 26b are connected together by a horizontal upper wall 26c.
[0156] Lateral walls 26a and 26b include laterally aligned apertures 54 and trunnions 53, respectively. These elements 53 and 54 are located substantially longitudinally in the middle of the lateral walls 26a and 26b of the adapter 26.
[0157] In a known manner, elements 53 and 54 define the approximate lateral axis Y of the pivotal articulation of connector 24 relative to adapter 26 and thus wiper 12 relative to drive arm 14.
[0158] The connector 24 essentially includes a lower portion 24a for crimping or securing to the remainder of the wiper 12, and an upper portion 24b for receiving between the inner surfaces of the side walls 26a, 26b of the adapter 26.
[0159] The upper part 24b includes a device 56 that complements elements 53 and 54 for alignment with axis Y.
[0160] As an alternative, in adapter 26 and connector 24, one may include a cylindrical trunnion centered on axis Y and used for fastening to one or more complementary apertures of the other of these components by means of a resilient clip.
[0161] At its front longitudinal end, the body 25 of the adapter 26 here - non-limitingly - includes two retaining tabs 62a, 62b, each retaining tab extending longitudinally forward in a continuation of the associated lateral walls 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 a component carried by the yoke 28.
[0163] Here, retaining tabs 62a and 62b in complementary recesses for engaging with end member 44 mounted at the front free end of the yoke 28 of the arm also allows for the positioning of adapter 26.
[0164] The tabs 62a and 62b are kept substantially parallel, each having an overall cuboid shape, and they extend vertically over most of the height of the lateral walls 26a and 26b.
[0165] As an alternative not shown, the body 25 of the adapter 26 may include a single retaining tab that extends horizontally and longitudinally forward in a 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 a component carried by the yoke 28.
[0166] By way of a non-limiting example, at its rear longitudinal end, the body 25 of the adapter 26 here includes two retaining tabs 63a, 63b, each retaining tab extending longitudinally rearward in a continuation of the relevant lateral walls 26a, 26b of the body 25 of the adapter 26.
[0167] Each retaining tab 63a, 63b is shaped to cooperate with the yoke 28 or a component carried by the yoke 28.
[0168] The tabs 63a and 63b are kept substantially parallel, each having an overall cuboid shape, and they extend vertically below the height of the lateral walls 26a and 26b.
[0169] Near its rear longitudinal end, the body 25 of the adapter 26 includes a locking tab 100 configured to be received through a hole in the yoke 28, in this case, a rear opening 38b of a generally rectangular profile in the upper wall 34 of the yoke 28.
[0170] The rear opening or hole 38b is defined longitudinally toward the rear via the rear transverse edge 39b, and the locking tab 100 cooperates with the rear transverse edge 39b, as will be explained later.
[0171] Especially in Figure 6 As can be seen, the locking tab 100 extends vertically above the horizontal plane of the outer surface 29 of the upper wall 26c of the body 25 of the adapter 26.
[0172] The retaining tabs 62a, 62b and the locking tab 100 are arranged longitudinally on each side of the pivotal hinge axis YY of the adapter 26 relative to the connector 24.
[0173] The locking tab 100 is longitudinally positioned between the axis YY of the pivotal articulation of the adapter 26 relative to the connector 24 and the retaining tabs 63a, 63b.
[0174] The locking tab 100 is configured to receive through an opening 38b in the yoke 28 and includes a free upper portion 102 shaped like a hook.
[0175] For example, in particular Figure 5A and 5B As can be seen in the perspective view, the hook-shaped part 102 is a solid part that is horizontally centered relative to the body 25 of the adapter 26.
[0176] The hook-shaped portion 102 includes a vertical central branch 104, which extends from a locking branch 106, which extends longitudinally rearward.
[0177] The locking branch 106 is defined vertically downward by a lower surface 108 shaped as a small plane, which in this example is horizontally oriented as a whole and is configured to cooperate with the opposite portion of the outer surface of the yoke 28.
[0178] In the installed and locked position, the lower surface 108 is supported by a portion 35 of the outer surface of the upper wall 34 of the yoke 28, which is located directly behind the rear lateral edge 39b of the rear opening 38b.
[0179] The vertical branch 104 of the hook-shaped portion 102 of the locking tab 100 includes a rear surface 110 for contacting the rear lateral edge 39b of the rear opening 38b of the yoke 28.
[0180] In this case, the rear contact surface 110 (by way of a non-limiting example) is a planar surface that extends in an overall vertical plane and is capable of contacting the rear lateral edge 39b of the rear opening 38b of the yoke 28, which is a straight lateral edge.
[0181] The upper part of the locking branch 106 of the hook portion 102 includes a shaped surface portion 112 forming a cam that is capable of cooperating with the rear lateral edge 39b of the rear opening 38b of the yoke 28 to move the hook 102 longitudinally forward relative to the body 25 of the adapter 26.
[0182] In this case, the shaped surface 112 is part of the arc of the convex cylinder.
[0183] The locking tab 100 is connected to the body 25 of the adapter 26 via a vertical connecting portion that is elastically deformable to allow the rear contact surface 110 to move longitudinally in both directions relative to the body 25 of the adapter 26.
[0184] exist Figures 3 to 7In the embodiment shown, the vertical connection portion connecting the locking tab 100 to the body 25 of the adapter 26 includes two laterally opposed 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 rear end of the latter.
[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 4 The position shown indicates that a portion of the convex profile surface 112 contacts the rear lateral 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 to introduce the locking tab 100 through the rear opening 38b, a cam effect occurs between the surface 112 and the edge 39b, causing the fixing tab to pivot more or less about the transverse axis ZZ.
[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 contacts the rear lateral edge 39b of the rear opening 38b of the yoke 28, bearing the latter with a slightly elastic contact and load carried together in the entire longitudinal direction.
[0197] When it is desired to remove the wiper, the hook-shaped upper part 102 protrudes above the outer surface of the upper wall 34 of the yoke 28.
[0198] Therefore, it constitutes an unlock "button" that the user can use to move it longitudinally forward by resisting the elasticity of the vertical connecting parts 114a and 114b.
[0199] To make this process easier, the convex profile surface can be ribbed or have any suitable special surface finish.
[0200] The aim is to avoid any risk of accidental separation between the wiper arm and the wiper, thereby preventing wiper loss, even under heavy loads.
[0201] This heavy load occurs particularly when windshield wipers are used on glass surfaces covered with ice or with a considerable layer of snow.
[0202] For this purpose, in order to avoid any risk of breakage of the locking tab 100, especially the free upper part 102 of which forms the hook, under load, the locking branch 106 is able to elastically deform relative to the vertical branch 104 by means of the yoke under the force applied to it.
[0203] As in Figure 7 As can be seen, and thanks to this ability to elastically deform, the locking branch 106 is particularly capable of pivoting relative to the vertical branch 104 about the transverse axis XX.
[0204] Here, the transverse axis XX is adjacent to the rear edge of the lower surface 108 and is substantially adjacent to the vertical branch 104.
[0205] In order to make the locking branch 106 more elastically deformable and pivot about the transverse axis XX, the hook portion 102 includes a recess 122 formed in the connection area between the vertical branch 104 and the locking branch 106.
[0206] The recess 122 is formed here in the continuation of the lower surface 108 of the locking branch 106.
[0207] Recess 122 is a groove oriented laterally.
[0208] As from Figure 7 As can be seen in the large proportion, the lower surface 108 of the locking branch 106 is connected to the groove 122 via a lateral corner 124, which can cooperate with the opposite portion 35 of the outer surface of the upper wall 34 of the yoke 28.
[0209] The ability to lock the branch in elastic deformation without breaking and to pivot about the transverse axis XX Figure 7 As shown, the locked branch 106 is depicted in its undeformed free state with solid lines, and in its state of deformation and pivoting in a counterclockwise direction with dashed lines 106', 108', 112'.
[0210] The adapter 1026 according to the second embodiment is substantially similar in form and overall design to the adapter 26 of the first embodiment.
[0211] The adapter 1026 includes an elongated rear body 1025, which is shaped to be mounted in the yoke 28.
[0212] In a cross-section in the transverse and vertical planes, the adapter 1026 is substantially inverted U-shaped. It includes two vertical and longitudinal lateral walls 1026a, 1026b, which are defined longitudinally toward the front via the front longitudinal end vertical edges 1027a, 1027b and longitudinally toward the rear via the rear longitudinal end vertical edges 1127a, 1127b.
[0213] The two lateral walls 1026a and 1026b are connected together by a horizontal upper wall 1026c.
[0214] As in the first embodiment, the body 1025 of the adapter 1026 includes a locking tab 100 configured to be received through a hole in the yoke 28, which in this case is a rear opening 38b of a generally rectangular outline of the upper wall 34 of the yoke 28.
[0215] The locking tab 100 is connected to the body 1025 of the adapter 1026 via a vertical branch 104, which is elastically deformable 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 also includes two retaining tabs 1062a, 1062b, each retaining tab extending longitudinally forward in a continuation of the relevant lateral walls 1026a, 1026b of the body 1025 of the adapter 1026.
[0217] The protrusions 1062a and 1062b are kept substantially parallel. Each of them has an overall cuboid shape.
[0218] Each retaining tab 1062a, 1062b includes 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 a component carried by the yoke 28. Chamfers 1126a, 1126b make it easier to insert the adapter 1026 into the yoke 28 or a component carried by the yoke 28, such as the end component 44 described herein by way of non-limiting example.
[0220] The retaining tabs 1062a and 1062b provide vertical retention for the adapter 1026.
[0221] By way of a non-limiting example, at its rear longitudinal end, the body 1025 of the adapter 1026 includes two retaining tabs 1063a, 1063b, each retaining tab extending longitudinally rearward in a continuation of the associated lateral walls 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 a component carried by the yoke 28.
[0223] The tabs 1063a and 1063b are kept substantially parallel. They are connected by transverse and horizontal rear transverse members 1128.
[0224] Each retaining tab 1063a, 1063b has an overall cuboid shape and extends vertically above the lower portion of the height of the associated vertical lateral walls 1026a and 1026b.
[0225] The retaining tabs 1063a and 1063b have a rear end that abuts against the yoke 28 or a component carried by the yoke 28.
[0226] The rear transverse member 1128 extends horizontally between the two retaining tabs 1063a and 1063b. It connects the rear ends of the retaining tabs 1063a and 1063b.
[0227] The width of the rear transverse member 1128 (measured in the longitudinal direction) corresponds to more than half the length of the retaining tabs 1063a and 1063b.
[0228] Calculate the lengths of retaining tabs 1063a and 1063b such that the rear end of each retaining tab 1063a and 1063b is adjacent to the yoke 28 or a component carried by the yoke 28.
[0229] Therefore, retaining tabs 1063a and 1063b are used to hold the adapter in the rearward longitudinal direction. If the wipers are pulled longitudinally rearward relative to the yoke 28, they significantly prevent damage to the locking tab 100.
[0230] The rear transverse member 1128 can increase the stiffness of the rear end of the adapter 1026, and in particular, can increase the stiffness of the retaining tabs 1063a and 1063b.
[0231] By way of a non-limiting example, at its front longitudinal end, the body 1025 of the adapter 1026 includes two front stops 1029a, 1029b with convex curved or coiled profiles, each of these end stops defining a convex curved stop surface 1130a, 1130b for longitudinally positioning the adapter 1026 relative to the yoke 28 or a component such as the end member 44 carried by the yoke 28.
[0232] Each stop 1029a, 1029b extends vertically downward in a curve in the continuation of the relevant side walls 1026a, 1026b of the body 1025 of the adapter 1026.
[0233] Each bending stop 1029a, 1029b is laterally adjacent to the outer surface of the associated retaining tab 1062a, 1062b.
[0234] The longitudinal thickness of each stop 1029a, 1029b decreases vertically from top to bottom to create a forward-facing convex curved profile (see...). Figure 12 ).
[0235] Therefore, the convex stop surfaces 1130a and 1130b have an upper transverse edge that is longitudinally offset forward relative to the lower transverse edge of the convex stop surfaces 1130a and 1130b.
[0236] The convex bending stops 1029a and 1029b allow the adapter to be longitudinally positioned on the yoke 28 or on a component carried by the yoke 28, such as the end component 44.
[0237] When the adapter 1026 and yoke 28 associated with end member 44 are assembled, the convex stop surfaces 1130a, 1130b of the bending stops 1029a, 1029b longitudinally abut against the yoke 28 or a portion of the end member 44 facing it (see...). Figure 21 Therefore, the curved profiles of the curved stops 1029a and 1029b serve as assembly guides, allowing the adapter 1026 to be pre-positioned longitudinally in the yoke 28.
[0238] This pre-positioning occurs gradually, and the convex surface facilitates the relative pivoting movement of the adapter relative to the yoke during assembly.
[0239] By way of non-limiting example, each of the lateral walls 1026a, 1026b includes a tab that is elastically deformable in the lateral direction, referred to as elastic tabs 1132a, 1132b.
[0240] Elastic tabs 1132a and 1132b are located on the front or front portion of the lateral walls 1026a and 1026b. They extend within approximately 20% to 50% of the length of the lateral wall, or even more preferably 25% to 35% of that 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 defined by two horizontal parallel grooves 1136a, 1136b and a front vertical groove 1138a, 1138b, which connects the two parallel grooves 1136a, 1136b. These grooves are formed in and extend through the corresponding lateral walls 1026a, 1026b.
[0243] In an alternative form not shown, it is also conceivable that the elastic tab has a vertical overall orientation orthogonal to the upper wall 1026c.
[0244] In this configuration, the front free end of each elastic tab 1132a, 1132b includes a longitudinally retaining lug or tooth 1134a, 1134b configured to cooperate with the yoke 28 and / or the component carried by the yoke 28 and / or the cap 30.
[0245] The lugs 1134a and 1134b protrude laterally outward relative to the plane of the associated elastic tabs 1132a and 1132b.
[0246] The lug has a triangular cam profile with upper ramps 1133a, 1133b, lower ramps 1135a, 1135b, front ramps 1137a, 1137b, and rear ramps 1139a, 1139b.
[0247] The front surfaces 1137a, 1137b of each retaining lug 1134a, 1134b are longitudinally supported on the yoke 28. The retaining lugs 1134a, 1134b thus allow the adapter 1026 to be fixed relative to the yoke 28 in the forward longitudinal direction.
[0248] The lengths of the upper slopes 1133a and 1133b are greater than the lengths of the lower slopes 1135a and 1135b.
[0249] The upper ramps 1133a, 1133b of the lugs 1134a, 1134b allow each elastic tab 1132a, 1132b to retract so as 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 ramps 1135a and 1135b of the lugs 1134a and 1134b allow each elastic tab 1132a and 1132b to retract over the longitudinal flange 42a located at the front of the cap 30 when the adapter 1026 is removed.
[0251] Due to their elasticity and 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 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 profiles of lugs 1134a and 1134b can be trapezoidal with upper and lower ramps. The operation of the elastic tabs is then substantially similar.
[0253] The lateral walls 1026a, 1026b include projecting posts 1140a, 1140b, 1142a, 1142b, configured to cooperate with yoke 28 and / or cap 30. Posts 1140a, 1140b, 1142a, 1142b project laterally outward and each has an integral cubic shape.
[0254] In the second embodiment, by way of a non-limiting example, each sidewall 1026a, 1026b includes two front columns 1140a, 1140b and two rear columns 1142a, 1142b.
[0255] The front pillars 1140a and 1140b are located at the front of the side walls 1026a and 1026b. They are configured to cooperate with the cap 30 and abut the front end of the notch 42a of the cap 30.
[0256] The front posts 1140a and 1140b ensure that during the installation of the adapter 1026, the cap 30 slides rearward relative to the yoke 28 in the closed position.
[0257] This is because when the cap 30 is in the forward-sliding open position, the flange 42b of the cap 30 is located below the position for receiving the front posts 1140a, 1140b, thereby preventing the adapter 1026 from being installed and assembled in the yoke 28.
[0258] The rear posts 1142a and 1142b are located on the rear portion of the side walls 1026a and 1026b. In the illustrated embodiment, the rear posts 1142a and 1142b protrude laterally from the retaining tabs 1063a and 1063b.
[0259] The rear posts 1142a and 1142b are configured to cooperate with the yoke 28, and in particular with the rear recess 33d. They are mated to the front edge of the associated rear recess 33d in such a way as to provide longitudinal retention of the adapter 1026 relative to the yoke 28 in the rearward direction.
[0260] Therefore, the retaining lugs 1134a, 1134b of the elastic tabs 1132a, 1132b and the front posts 1140a, 1140b provide the adapter 1026 with a double "fixation" longitudinally forward relative to the yoke, especially under significant loads.
[0261] The rear pillars 1142a and 1142b also press slightly upward against the upper horizontal edge of the rear recess 33d.
[0262] The bottom of the side walls 1026a and 1026b includes bottoms 1143a and 1143b, which have a convex profile with an arc or circle shape.
[0263] In the second embodiment, the circular bottoms 1143a and 1143b have additional lateral thicknesses on the outer side, thus increasing the stiffness of the lower part of the sidewalls 1026a and 1026b.
[0264] This additional thickness allows the adapter 1026 to better withstand the torsion and deformation that it may experience under heavy loads, which could occur on glass surfaces covered with ice or snow when using a windshield wiper.
[0265] Specifically, once the adapter 1026 is installed on the wiper 12, the lower part of the adapter 1026 is exposed to the open air and may be attacked from the external environment, especially in severe weather conditions such as snow or ice.
[0266] The bottom of the adapter 1026, 1143a and 1143b, also includes circular protrusions, 1144a and 1144b.
[0267] like Figure 20 As can be seen, the circular protrusions 1144a, (1144b) pivotally abut against the opposite upper lateral facets 1145a, (1145b) of the connector 24 to provide vertical retention of the adapter 1026 relative to the connector 24 in the downward direction.
[0268] The adapter 1026 includes at least one pickup area 1146 and 1148 for positioning the suction cup so that the machine can pick up the adapter 1026 when it is factory-installed on the wiper 12.
[0269] For example, the rear lateral member 1128 has a horizontal rear extension 1146 corresponding to the first pickup area. The rear extension 1146 includes a rounded rear edge that extends from the rear lateral member 1128 and makes it easier to position the pickup suction cup (not shown).
[0270] The horizontal upper wall 1026c also has a horizontal upper extension 1148, which has a circular rear edge corresponding to the second pickup area.
[0271] In an alternative form of the embodiment not shown, the upper wall of the adapter body may include an elastically deformable tongue configured to abut against the inner surface of the upper wall of the yoke member in order to eliminate any gaps that may exist between the adapter and the inner surface.
[0272] Such a gap-compensating tongue is located, for example, 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 installation and assembly of adapter 1026 in yoke 28 are similar to those described with reference to the first embodiment.
[0274] The adapter 1026 is installed, and can only be installed when the cap 30 is in the closed position with its back slid-back.
[0275] First, the tabs 1062a and 1062b are held in complementary recesses in the end member 44, which is mounted at the front free end of the yoke 28 of the arm. The presence of chamfers 1126a and 1126b facilitates their engagement.
[0276] Then, by pivoting adapter 1026 upwards, adapter 1026 is brought into position. Figure 4 The location shown.
[0277] The bending stops 1029a and 1029b facilitate the pivoting of the adapter 1026, which longitudinally abut against the end member 44.
[0278] During pivoting or tilting, the retaining lugs 1134a, 1134b of the elastic tabs 1132a, 1132b retract due to the upper ramps 1133a, 1133b, allowing them to pass over the longitudinal flange 42a located at the front of the cap 30.
[0279] The front surfaces 1137a and 1137b of the lugs 1134a and 1134b abut against the yoke 28, providing longitudinal retention of the adapter 1026 in the forward direction.
[0280] Next, the front posts 1140a and 1140b pass over the flange 42a of the cap 30 to ensure that the latter is indeed in the closed position.
[0281] Finally, the rear posts 1142a and 1142b are inserted into the rear recess 33d and abut against the front edge of the rear recess 33d to provide longitudinal retention of the adapter 1026 in the rearward direction.
[0282] Then, the adapter is in Figures 16 to 22 The location is specifically shown in the text.
[0283] At this position, a portion of the convex profile surface 112 contacts the rear lateral edge 39b of the rear opening 38b of the yoke 28.
[0284] Then, the locking tab 100 is locked in the rear opening 38b of the yoke 28 as in the first embodiment.
[0285] To remove the adapter 1026 of the second embodiment from the wiper 12, the process is similar to that in which the adapter 26 of the first embodiment is removed.
[0286] Once the locking tab 100 is unlocked and pulled out from the rear opening 38b by the downward pivoting adapter 1026, the retaining lugs 1134a, 1134b of the resilient tabs 1132a, 1132b retract due to the downward ramps 1135a, 1135b, allowing them to pass over the longitudinal flange 42a located at the front of the cap 30.
[0287] The adapter 1026 can be finally completely disassembled by disengaging the retaining tabs 1062a, 1062b from the complementary recesses in the end part 44 of the yoke 28 of the arm.
