Description

Title of the invention: Adapter for motor vehicle wiper blade

Technical area

The present invention is in the field of wiper blades of a motor vehicle window, and relates more particularly to adapters for fixing the wiper blade on an arm of a system d 'wiping.

State of the art

In the field of motor vehicles, wiping systems make it possible to wipe a glass wall of a motor vehicle. Generally, such a wiping system includes one or more articulated wiping broom (s) so that it can be moved against the glass wall. Each wiper blade comprises a structure supporting a wiper blade intended to be brought into contact against the glass wall so as to be able to evacuate the water out of the glass wall. In addition, each wiper blade includes a connector secured to the structure and an adapter pivotally mounted on the connector to allow a detachable attachment of a wiper system arm on the wiper blade adapter. -ice.

In known manner, the adapter of the wiper blade is engaged in a yoke of the arm by means of a longitudinal translational movement to a direction of elongation of the yoke. To this end, the yoke includes two folded edges which allow the adapter to be guided longitudinally during assembly and to keep it in the yoke in its functional configuration with the wiping system.

There are many types of adapters for different types of wiper blades and different types of arms. In general, a known adapter comprises (i) two side walls spaced from one another and connected to each other by an upper wall, each side wall comprising a lower bearing face allowing it to be pressed against one of the folded edges of the yoke of the arm, and (ii) a member for coupling the adapter with the yoke.

DE 10 2008 011 449 A1 is known in particular in which, due to a curved shape of the clevis of the articulated arm preventing insertion of the adapter from one of its longitudinal ends, the adapter is first inserted into the screed - at a central zone of the screed - in a translational movement towards a concavity of the screed, perpendicular to the direction of elongation of the screed and between two distant segments of each edge folded.

This type of assembly leads to a complex geometry of the adapter: each side wall of the adapter comprises two end parts spaced longitudinally from each other and separated by a central notch which extends from the upper wall. The central notch is located longitudinally at the axis of rotation of the adapter. This configuration allows you to insert the adapter towards the concavity of the yoke by placing one of the two segments of the folded edges of the yoke at the center notch of the adapter. At the end of this translation towards the concavity of the yoke, the adapter is then engaged longitudinally in the yoke until its functional configuration with the arm. In this functional configuration, each segment of the folded edges of the yoke is engaged with each end portion situated opposite the side walls of the adapter: the folded edges of the yoke are not engaged with the adapter at the level of the 'central notch, which can lead to instability and / or poor coupling of the adapter in the arm clevis.

We also know the document W02010 / 034445A1 in which a longitudinal end of the adapter comprises a tongue which extends projecting relative to the lateral sides of the adapter. During assembly, the adapter is engaged in the yoke of the arm at a longitudinal front end of the yoke, until it is in functional configuration with the arm. In this functional configuration, the tongue then protrudes from the longitudinal end of the yoke: it does not collaborate with the yoke of the arm but with a closure cover attached to the yoke of the arm.

In order to secure the adapter in the yoke in the event of a malfunction of the coupling member of the adapter, one of the folded edges of the yoke comprises a lug which collaborates with one of the side walls of the 'adapter, at a distal end relative to the upper wall. This configuration allows the adapter to be retained if the adapter coupling member is torn off, thus preventing the wiper blade from being ejected from the arm. The disadvantage lies in the complexity of implementation of the lug on the folded edge of the yoke, leading to an increase in manufacturing costs. In addition, this configuration also leads to providing a complementary surface at the level of the adapter in order to collaborate with the lug to retain the adapter.

The object of the present invention is to respond at least in large part to the above problems and to also lead to other advantages by proposing a new adapter for fixing a wiper blade on an arm of wiping system.

Another object of the invention is to allow easier mounting of such an adapter by a rear longitudinal end of the yoke of the arm.

Another object of the invention is to secure the adapter in the yoke of the arm in the event of a malfunction.

Another object of the invention is to simplify the manufacture of such an adapter and to reduce manufacturing costs.

Statement of the invention

According to a first aspect of the invention, at least one of the abovementioned objectives is achieved with an adapter for fixing a wiper blade to an arm of a wiping system, the adapter being configured to be pivotally mounted about an axis of rotation on a connector of the wiper blade, the adapter comprising (i) two side walls spaced from each other and connected to each other by an upper wall , each side wall of the adapter comprising a lower bearing face on a folded edge of a yoke of the arm, and (ii) a member for coupling the adapter with the yoke. According to the invention, a first longitudinal end of the adapter forms a securing means configured to retain the adapter in the yoke of the arm when the coupling member is uncoupled from the yoke, and the lower support face d 'at least one of the side walls extends to the right of the axis of rotation.

In other words, the securing means of the adapter is configured to be pressed against a longitudinal end of the yoke of the arm when the coupling member is uncoupled from the yoke, and preferably against one end longitudinal front of the yoke. In fact, the adapter according to the first aspect of the invention intended more particularly to be assembled on the associated wiping system by translation from a rear longitudinal face of the arm, the yoke of such an arm is advantageously closed to the front, that is to say at a longitudinal end opposite to that by which the adapter is introduced into the yoke.

To this end, at the first and a second longitudinal end of the adapter, the longitudinal end of the upper wall extends longitudinally at most up to the corresponding longitudinal end of the side walls: the upper wall of the adapter according to the invention does not include a tongue which projects in relation to the side walls; and an interaction between the securing means and the arm clevis - in the event of a malfunction of the coupling member occurs at the longitudinal ends of the side walls of the adapter according to the first aspect of the invention.

The securing means intervenes during an untimely uncoupling of the adapter with the yoke of the arm, the uncoupling resulting from an involuntary separation, a malfunction or a break in the coupling member during the operation of the wiping system. Therefore, when the coupling member of the adapter is uncoupled from the yoke of the arm during the operation of the wiping system, then the means of securing the adapter - propelled towards the front longitudinal end of the yoke under the effect of the centrifugal force linked to the rotational movement of the wiper blade on the glass surface - abuts against the front and closed longitudinal face of the yoke: the adapter is thus retained in the yoke and the blade is not separated from the arm in the event of a malfunction.

The lower bearing face corresponds to a bearing face of the adapter on the folded edge of the yoke of the arm with which the adapter is intended to collaborate, when the adapter is engaged in the yoke of the arm and in the functional configuration of the wiping system.

More particularly, the lower bearing face of the adapter extends perpendicular to a lateral end of the axis of rotation, relative to a vertical axis of the adapter. In other words still, at a lateral end of the axis of rotation, there is a vertical line, perpendicular to the axis of rotation, which intersects with the lower bearing face of the adapter.

The invention according to the first aspect of the invention is intended both for the original equipment market and for the aftermarket of wiping systems and / or wiper blades and / or adapters for such wiper blades.

In the context of the invention, the following adjectives are defined relative to the adapter according to the first aspect of the invention:

By extension, the longitudinal direction refers to a direction which is parallel or substantially parallel to the greatest length of the wiping blade; and the adjectives "front" and "rear" refer to a relative position along the longitudinal axis;

The adjective "transverse" or "lateral" refers to a direction of elongation perpendicular to the longitudinal direction, and more particularly a direction perpendicular to the two lateral edges of the cover of the adapter;

The adjective "vertical" refers to a direction simultaneously perpendicular to the longitudinal direction and the transverse direction. By way of example, a vertical direction refers in particular to the relative position of the wiping blade relative to the adapter according to the first aspect of the invention. By extension, the adjectives "lower" and "upper" refer to a relative position along the vertical axis.

The adapter according to the first aspect of the invention may advantageously comprise at least one of the improvements below, the technical characteristics forming these improvements can be taken alone or in combination:

The adapter according to the first aspect of the invention has a transverse U-shaped profile. In other words, the upper wall laterally separates the two side walls of the adapter. In particular, the side walls are laterally spaced from each other, thus delimiting - with the upper wall - a housing for the connector of the wiper blade;

In order to facilitate insertion of the adapter according to the first aspect of the invention in the yoke of the arm with which it is intended to collaborate, the side walls of the adapter are parallel to each other. More particularly still, the side walls are perpendicular to the upper wall of the adapter according to the first aspect of the invention;

The upper wall and / or the side walls of the adapter according to the first aspect of the invention is flat. This advantageous configuration makes it easier to insert the adapter according to the first aspect of the invention into the yoke of the arm with which it is intended to collaborate. In particular, an upper face of the upper wall of the adapter is flat in order to facilitate its collaboration with the yoke of the arm, and / or a lower face of the upper wall of the adapter is flat in order to facilitate the insertion of the wiper blade connector in the adapter. Similarly, an outer face of the side walls is advantageously planar in order to facilitate their collaboration with the yoke of the arm, and / or an inner face of the side walls is advantageously planar in order to facilitate the insertion of the connector of the wiper blade. ice in the adapter;

At the first and a second longitudinal end of the adapter, the longitudinal end of the upper wall extends longitudinally at most up to the corresponding longitudinal end of the side walls. This advantageous configuration makes it possible both to facilitate the collaboration of the adapter according to the first aspect of the invention with the longitudinal end of the yoke of the arm in which the adapter is intended to be inserted: the upper wall of the adapter does not protrude longitudinally from the side walls of the adapter. This configuration is particularly suitable for arm screeds which are closed at their front longitudinal end, requiring insertion of the adapter by a rear longitudinal end;

Advantageously, the distal ends of the side walls of the adapter are coplanar. In other words, the undersides of the side walls are located at the same distance from the top wall of the adapter. This advantageously symmetrical configuration makes it easier to insert the adapter into the yoke of the arm with which it is intended to collaborate, and to reduce the manufacturing costs of the adapter and the corresponding yoke;

On a first side wall of the adapter, the axis of rotation is formed by a cylindrical housing formed from an inner face of the first side wall of the adapter. The axis of rotation is then defined by a central axis of the cylindrical housing. The cylindrical housing extends from the inside of the first side wall of the adapter according to the first aspect of the invention and towards the outside of the first side wall.

In other words, the lower bearing face of the first side wall extends longitudinally at least between longitudinal sides longitudinally delimiting the cylindrical housing. In still other terms, the lower bearing face of the first side wall of the adapter according to the first aspect of the invention extends longitudinally at least between the walls of the cylindrical housing delimited by the peripheral contour;

On a second side wall of the adapter, the axis of rotation is formed by a cylindrical sleeve which projects from an inner face of the second side wall of the adapter, the cylindrical sleeve being coaxial with the cylindrical housing. Thus, the axis of rotation of the adapter according to the first aspect of the invention is not materialized on said adapter by the same shapes between its two side walls: on the second side wall, the axis of rotation does not is not formed by the cylindrical housing of the first side wall, but by a cylindrical sleeve. This advantageous configuration makes it possible to form a rotation bearing facilitating the stability of the pivoting mounting of the adapter according to the first aspect of the invention on the connector of the wiper blade with which it is intended to collaborate;

The lower bearing face of the second side wall of the adapter extends at least directly above the cylindrical sleeve. In other words, the lower bearing face of the second side wall extends longitudinally at least between the blanks forming the cylindrical sleeve;

The coupling member is located at the top wall of the adapter according to the first aspect of the invention. This advantageous configuration makes it easier to collaborate with the yoke of the arm in which the adapter according to the first aspect of the invention is inserted, by making it possible to couple the adapter with an upper face of the yoke;

The coupling member comprises a support button located at one end of a support surface. This advantageous configuration makes it possible to selectively activate or deactivate the coupling member in order to couple or uncouple the adapter and the yoke respectively. To this end, the coupling member is advantageously connected to the upper wall of the adapter by means of a flexible hinge configured to allow elastic deformation of the bearing surface of the coupling member relative to the top wall of the adapter;

The button of the coupling member is located beyond a longitudinal end of the adapter. In other words, the coupling member - and more particularly its bearing surface - extends longitudinally beyond a longitudinal end of the side walls of the adapter. This advantageous configuration makes it possible to lengthen the bearing surface of the coupling member and - consecutively - to increase a lever arm effect at the level of the support button located at the end of the bearing surface. Alternatively, the button of the coupling member is located longitudinally between the first and second longitudinal ends of the side walls of the adapter, along the longitudinal axis of the adapter extending from the rear towards the 'front of the adapter;

This first embodiment variant is called a mono-vertebra. In such a case, the vertebra is housed in a tunnel of a plastic support on which the connector is attached and which also includes claws for hooking a heel of the wiping blade. It is also possible that the connector is hooked directly to the vertebra and that a heel of the wiper blade is glued against one side of this unique vertebra.

Alternatively, according to a second variant embodiment, the structure supporting the wiping blade is of the type of a structure comprising two vertebrae distributed laterally on either side of a dorsal of the wiping blade. This second variant is called bi-vertebrae.

According to a third aspect of the invention, there is provided a wiping system comprising at least one wiper blade, according to the second aspect of the invention, detachably fixed via the adapter to a arm, the arm comprising a yoke mechanically coupled to the adapter by engagement of complementary shapes.

The folded edge of each side edge of the yoke is located at a free end of the side edge. The two lateral edges of the yoke form between them a concave volume inside which the adapter can be inserted by translation in a longitudinal direction of extension of the yoke. The folded edges of the yoke against which the adapter according to the first aspect of the invention is supported thus make it possible to guide the adapter during its longitudinal insertion in the yoke of the arm. In addition, when the adapter has reached its functional configuration with the arm, the folded edges of the yoke help to keep the adapter in position in the arm yoke;

The side walls of the adapter bear against the side edges of the yoke of the arm. In particular, the side walls of the adapter according to the first aspect of the invention are in lateral support against the lateral edges of the yoke of the arm during the insertion of the adapter into the yoke and / or in the functional configuration of the adapter in the yoke;

The yoke of the arm includes a closing edge which extends laterally between the two lateral edges at a longitudinal end of the yoke. In other words, the yoke of the arm of the wiping system according to the third aspect of the invention is more particularly of the type of a yoke open at the rear, that is to say towards the pivot point. of the arm, and which allows the insertion of the adapter into the yoke only by its rear longitudinal end. In addition, the closure edge of the yoke allows, in collaboration with the adapter securing means according to the first aspect of the invention, to retain the adapter when the coupling member of the adapter with the yoke disengages from the yoke during operation of the wiping system: the securing means is then placed in longitudinal abutment against the closing edge of the yoke, thus preventing the wiper blade from being propelled out of the arm;

The yoke includes an upper edge connecting the two lateral edges, the upper edge comprising an opening configured to allow the engagement of the coupling member when the adapter is coupled to the arm. Preferably, the opening formed in the upper edge of the arm clevis is configured to allow the engagement of the button of the coupling member when the adapter is coupled to the arm.

Referring to FIGURES IA to 1F, an exemplary embodiment of an adapter 300 according to the first aspect of the invention is first described.

Such an adapter 300 includes:

Two side walls 320, 330 distant from one another and connected to each other by an upper wall 340, so that, in a transverse plane formed by the transverse axis Y and by the vertical axis Z, the adapter 300 has a U-shaped profile, as more particularly visible in FIGURE 1E;

A coupling member 360 of the adapter 300 with a yoke 650 - not shown in FIGURES 1 - of an arm 600 of the wiping system 700.

In the example illustrated in FIGURES 1, the side walls 320, 330 are mutually parallel and perpendicular to the upper wall 340 of the adapter 300. Optionally, the side walls 320, 330 can form an angle greater than 90 ° with the upper wall 340 as a function of the shape of the yoke 650 with which the adapter 300 is intended to collaborate.

At their upper vertical end, each side wall 320, 330 of the adapter 300 comprises a chamfer 327, 337 in order to facilitate its insertion into the yoke 650 of the arm 600 and in which the adapter 300 is intended for be inserted. In other words, in a transverse plane illustrated in FIGURE 1E in particular, the upper wall 340 of the adapter 300 comprises, at each of its lateral ends, a chamfer 327, 337. The chamfer is advantageously oriented at 45 ° relative to the upper wall 340 of the adapter 300. In addition, the chamfer 327, 337 of each of the side walls 320, 330 of the adapter 300 extends longitudinally between two longitudinal ends 321, 331, 322, 332 side walls.

Laterally, the first side wall 320 of the adapter 300 is delimited by an outer face 324 and by an inner face 325. The inner face 325 of the first side wall 320 is located opposite the second side wall 330 of the adapter 300. In the example illustrated in FIGURES IA, the inner face 325 and the outer face 324 of the first side wall 320 are advantageously plane and parallel to one another.

Longitudinally, the first side wall 320 of the adapter 300 is delimited by a first longitudinal end 321 located at the front of the adapter 300 and by a second longitudinal end 322 located at the rear of the adapter 300 , relative to the longitudinal axis X. The first 321 and the second 322 tudinal longi end of the first side wall 320 are advantageously plane and parallel to one another. The first side wall 320 also comprises a vertical chamfer which delimits the external face 324 of each of its longitudinal ends 321, 322.

Vertically, the first side wall 320 of the adapter 300 is delimited, on the one hand, by the upper wall 340 of the adapter 300 and, on the other hand, by a lower planar face forming a face of lower support 323, 333 of the adapter 300 and intended to collaborate with a folded edge 655 of the yoke 650 of the arm 600 with which the adapter 300 is intended to collaborate.

To facilitate the insertion of the adapter 300 into the yoke 650 of the arm 600 with which the adapter 300 is intended to collaborate, the first longitudinal end 321 of the first side wall 320 comprises, at its face lower support 323, a chamfer 328 which defines an edge inclined towards the second side wall 330.

Thus, the first side wall 320 of the adapter 300 has a generally parallelepiped shape which extends vertically below the upper wall 340 of the adapter 300, relative to the vertical axis Z.

As can be seen more particularly on the LIGURES IC, 1D and 1F, the first side wall 320 also includes two oblong openings 326a, 326b which extend longitudinally in the first side wall 320. The oblong openings 326a, 326b of the first side wall 320 are transverse along the vertical axis Z: they open simultaneously at the top wall 340 and at the bottom bearing face 323 of the first side wall 320. Laterally, the oblong openings 326a, 326b are located between the outer face 324 and the inner face 325 of the first side wall 320, preferably centered relative to the transverse axis Y of the adapter 300.

Similarly, the second side wall 330 of the adapter 300 is delimited laterally by an outer face 334 and by an inner face 335. The inner face 335 of the second side wall 330 is located opposite the first wall lateral 320 of the adapter 300. In the example illustrated in FIGURES IA, the internal face 335 and the external face 334 of the second lateral wall 330 are advantageously plane and parallel to one another.

Longitudinally, the second side wall 330 of the adapter 300 is delimited by a first longitudinal end 331 located at the front of the adapter 300 and by a second longitudinal end 332 located at the rear of the adapter 300 , relative to the longitudinal axis X. The first 331 and the second 332 longitudinal end of the second side wall 330 are advantageously plane and parallel to one another. The second side wall 330 also includes a vertical chamfer which delimits the external face 334 of each of its longitudinal ends 331, 332.

Advantageously, and as shown in FIGURES IC and ID in particular, the first 321 and the second 322 longitudinal end of the first side wall 330 on the one hand, and the first 331 and the second 332 longitudinal end of the second side wall 330 on the other hand are parallel to each other. Also preferably, the first 321 longitudinal end of the first side wall 330 and the first 331 longitudinal end of the second side wall 330 are coplanar; and the second longitudinal end 322 of first side wall 330 and the second longitudinal end 332 of second side wall 330 are coplanar.

Vertically, the second side wall 330 of the adapter 300 is delimited, on the one hand, by the upper wall 340 of the adapter 300 and, on the other hand, by a flat lower face forming the face of lower support 323, 333 of the adapter 300 and intended to collaborate with a folded edge 655 of the yoke 650 of the arm 600 with which the adapter 300 is intended to collaborate. As can be seen in FIGURE 1E, the lower planar surfaces of each side wall 320, 330 of the adapter 300 together form a single planar lower support face 323, 333. In other words, the lower planar surfaces of each side wall 320, 330 of the adapter 300 are advantageously coplanar.

To facilitate the insertion of the adapter 300 into the yoke 650 of the arm 600 with which the adapter 300 is intended to collaborate, the first longitudinal end 321 of the second side wall 330 comprises, at its face lower support 333, a chamfer 338 which defines an edge inclined towards the first side wall 320.

Thus, the second side wall 330 of the adapter 300 has a generally parallelepiped shape which extends vertically below the upper wall 340 of the adapter 300, relative to the vertical axis Z.

As seen more particularly in FIGURES IC, ID and 1F, the second side wall 330 also includes two oblong openings 336a, 336b which extend longitudinally in the second side wall 330. The oblong openings 336a, 336b of the second side wall 330 pass through along the vertical axis Z: they open simultaneously at the top wall 340 and at the bottom bearing face 333 of the second side wall 330. Laterally, the oblong openings 336a, 336b are located between the outer face 334 and the inner face 335 of the second side wall 330, preferably centered relative to the transverse axis Y of the adapter 300.

As shown in FIGURES ID, 1E and 1F, the side walls 320, 330 and the upper wall 340 of the adapter 300 together define a housing 350 allowing the insertion of a connector 200 of wiper blade glass 500 when the adapter 300 is pivotally mounted on said adapter 200. Thus, the housing 350 opens at the first longitudinal end 321, 331 of the side walls 320, 330 of the adapter 300 - preferably located at the front of adapter 300.

In the embodiment illustrated in FIGURES 1, the housing 350 of the adapter 300 also opens at the second longitudinal end 322, 332 of the side walls 320, 330 of the adapter 300 - preferably located at the rear of the adapter 300. In other words, the housing 350 passes longitudinally through the adapter 300 right through along its longitudinal axis X.

Relative to the lateral axis Y of the adapter 300, the housing 350 is delimited by the inner faces 325, 335 of the side walls 320, 330 of the adapter 300.

Relative to the vertical axis Z of the adapter 300, the housing 350 is delimited on an upper side by a lower face of the upper wall 340 of the adapter 300; and in a vertical direction opposite to the upper wall 340, the housing 350 is not delimited: it opens at the level of the lower bearing face 323, 333 of the adapter 300.

Subsequently, in a transverse plane formed by the transverse axis Y and the vertical axis Z, the housing 350 has a generally rectangular shape between the side walls 320, 330 and upper 340 of the adapter 300, as visible in FIGURE 1E more particularly.

As shown in FIGURES IC, ID and 1F, the upper wall 340 of the adapter 300 comprises, at the first longitudinal end 321, 331 of the side walls 320, 330, a through opening 370. The opening through 370 is formed from an upper face of the upper wall 340 of the adapter 300 and to the lower face of said upper wall 340, in the direction of the lower bearing face 323, 333 of the adapter 300 against a folded edge 655 of the yoke 650 of the arm 600 with which the adapter 300 is intended to collaborate. The through opening 370 thus takes the form of a notch through the upper wall 340.

Relative to the longitudinal axis X of the adapter 300, the through opening 370 of the upper wall 340 opens longitudinally at the first longitudinal end 321, 331 of the side walls 320, 330 of the adapter 300. In other words, longitudinally, the through opening 370 is delimited by a contour 371 open at the longitudinal end 341 of the upper wall 340. Thus, in the example illustrated in FIGURES IC, ID and 1F, the first longitudinal end 341 of the upper wall 340 extends longitudinally, at the level of the first longitudinal end of the adapter 300, at most up to the first longitudinal ends 321, 331 corresponding to the side walls 320, 330; and a second longitudinal end 342 of the upper wall 340 extends longitudinally, at the level of the second longitudinal end of the adapter

300, at most up to the second longitudinal ends 322, 332 corresponding to the side walls 320, 330. Subsequently, the upper wall 340 of the adapter 300 according to the invention does not include a tongue which projects in relation to the side walls 320 330.

Laterally, the through opening 370 of the upper wall 340 is delimited by the inner faces 325, 335 of the side walls 320, 330 of the adapter 300. Thus, the through opening 370 of the upper wall 340 of the adapter 300 has a generally rectangular shape.

In the example illustrated in LIGURES 1, the adapter 300 according to the first aspect of the invention is configured to be pivotally mounted about a rotation axis 310 on the connector 200 of the wiper blade on which it is intended to be mounted. To this end, the adapter 300 includes means configured to define the axis of rotation 310:

At the first side wall 320, the axis of rotation 310 is formed by a cylindrical housing 380 formed from the inner face 325 of the first side wall 320 and opening laterally at the outer face 324 of the first side wall 320. More particularly, the axis of rotation 310 is located in the center of the cylindrical housing 380, and the axis of rotation 310 is coaxial with the cylindrical housing 380;

At the second side wall 330, the axis of rotation 310 is formed by a cylindrical sleeve 390 which projects from an inner face 335 of the second side wall 330. More particularly, the axis of rotation 310 is located in the center of the cylindrical sleeve 390; and the axis of rotation 310 is coaxial with the cylindrical sleeve 390. In addition, the cylindrical sleeve 390 comprises a through opening 395 delimited by a circular outline 396, the through opening 395 being coaxial with the cylindrical sleeve 390. The through opening 395 of the cylindrical sleeve 390 passes laterally right through the second side wall 330 of the adapter 300. In addition, the cylindrical sleeve 390 is coaxial with the cylindrical housing 380.

According to the invention according to its first aspect, and as more particularly visible on the LIGURES IB and IL, the lower bearing face 323 of the first side wall 320 of the adapter 300 extends at least 1 plumb with the cylindrical housing 380. In other words, the lower bearing face 323 of the first wall 320 extends longitudinally between longitudinal sides 382a, 382b delimiting the cylindrical housing 380 longitudinally. Indeed, the cylindrical housing 380 is delimited by a peripheral contour 381 comprising the two longitudinal sides 382a, 382b. The peripheral contour 381 is advantageously polygonal, and preferably square in the example illustrated in LIGURES 1.

More generally, the lower bearing face 323 of the first side wall 320 of the adapter 300 is at least partly located between the two longitudinal sides 382a, 382b of the cylindrical housing 380. Consequently, the lower bearing face 323 of the first side wall 320 extends longitudinally beyond the longitudinal sides 382a, 382b of the cylindrical housing 380, towards the first 321 and / or the second 322 longitudinal end of the first wall lateral 320 of the adapter 300. Preferably, the lower bearing face 323 of the first lateral wall 320 extends longitudinally symmetrically with respect to the axis of rotation 310. Also preferably, and as visible in FIGURES 1 , the lower bearing face 323 of the first side wall 320 extends longitudinally along the entire first side wall 320, that is to say up to the first 321 and / or the second 322 longitudinal end of the first re side wall 320.

As shown in FIGURES IA, 1D and 1E, the lower bearing face 333 of the second side wall 330 of the adapter 300 extends at least directly above the cylindrical sleeve 390. In others terms, the lower bearing face 333 of the second wall 330 extends longitudinally between the circular contour 396 delimiting the through opening 395. More generally, the lower bearing face 333 of the second side wall 330 of the adapter 300 is at least partly located between the circular contour 396 delimiting the through opening 395. Optionally, the lower bearing face 333 of the second side wall 330 of the adapter 300 is at least partly located longitudinally between blanks delimiting the cylindrical sleeve 390.

As a result, the lower bearing face 333 of the second side wall 330 extends longitudinally beyond the circular outline 396 delimiting the through opening 395 and / or beyond the blanks delimiting the cylindrical sleeve 390, towards the first 331 and / or the second 332 longitudinal end of the second side wall 330 of the adapter 300. Preferably, the lower bearing face 333 of the second side wall 330 extends longitudinally symmetrically by relative to the axis of rotation 310. Also preferably, and as visible in FIGURES 1, the lower bearing face 333 of the second side wall 330 extends longitudinally along the entire second side wall 330, that is to say say up to the first 331 and / or the second 332 longitudinal end of the second side wall 330.

As mentioned above, and in accordance with the invention according to its first aspect, the adapter 300 comprises the coupling member 360 in order to allow mechanical coupling of the adapter 300 in the yoke 650 of the arm 600 to block longitudinally the adapter 300 in the yoke 650.

In the embodiment illustrated in FIGURES IA to 1F, the coupling member 360 is located at the top wall 340 of the adapter 300. In particular, the coupling member 360 comprises:

A bearing surface 362 connected to the upper wall 340 of the adapter 300 via a flexible hinge 365 configured to allow elastic deformation of the bearing surface 362 relative to the upper wall 340 of the adapter 300;

A support button 361 located at a free longitudinal end of the support surface 362.

The bearing surface 362 extends longitudinally from the second longitudinal end 342 of the upper wall 340 of the adapter 300. The bearing surface 362 has a prismatic shape. In addition, the bearing surface 362 forms with the upper wall 340 of the adapter 300 - in its natural configuration, that is to say without being subjected to any other force than its own weight - a non-zero angle, preferably less than 10 °, so that the free end of the bearing surface 362 is situated vertically above the upper face of the upper wall 340.

The button 361 has a polygonal shape, and in particular a square shape in the example illustrated in FIGURES IC, 1D and 1F. Laterally, the support button 361 is wider than the support surface 362, relative to the lateral axis Y. Vertically, the support button protrudes above the support surface 362, relative to the vertical axis Z.

The flexible hinge 365 is formed by two longitudinal notches 366 which laterally border the bearing surface 362 on either side, relative to the transverse axis Y. Due to the relatively small thickness of the scope of support 362, relative to the vertical axis Z - equal to or substantially equal to that of the upper wall 340 - a force exerted vertically on the support button 361 generates an elastic deformation of the support surface 362, leading to a movement of rotation of the coupling member 360 around the second longitudinal end 342 of the upper wall 340 of the adapter 300. As will be described later with reference to FIGURES 3A to 3D, the push button 361 is intended to collaborate with an opening 653 produced in the yoke 650 of the arm 600.

According to a feature of the invention according to its first aspect, the first longitudinal ends 321, 331, 341 of the side walls 320, 330 and upper 340 of the adapter 300 together form a securing means 100 for retaining the 'adapter 300 in the yoke 650 of the arm 600 with which it is intended to collaborate, when the coupling member 360 is uncoupled from the yoke 650. In fact, the securing means 100 formed by the first longitudinal ends 321, 331 of the side walls 320, 330 and by the first longitudinal end 341 of the upper wall 340 together form a flat surface which facilitates its abutment against a longitudinal end of the yoke 650, as will be described later with reference to FIGURES 3A to 3D. More particularly, the upper wall 340 does not extend longitudinally in front of the side walls 320, 330 of the adapter 300. Conversely, the upper wall 340 extends longitudinally - at most - at the side walls 320, 330 , but not beyond.

With reference to FIGURES 2A and 2B, the adapter 300 illustrated in FIGURES 1 is assembled on a wiper blade 500 comprising:

A structure 400 supporting a wiping blade 430;

A connector 200 fixed integrally to the structure 400;

An adapter 300 according to the first aspect of the invention or according to any one of its improvements, as described above, said adapter 300 being pivotally mounted on the connector 200.

FIGURE 2B illustrates a sectional view along a lateral plane YZ as shown in FIGURE 2A.

The structure 400 of the wiper blade 500 comprises a support 440 visible in FIGURE 2B and which directly supports the wiping blade 430. The support 440 is fixed integrally to the structure notably by means of an end piece 420. Vertically, the wiping blade 430 and the support 440 are surmounted by a deflector 410, relative to the vertical axis Z.

The connector 200 is fixedly attached to the structure 400 of the wiper blade 500 and acts as a mechanical interface with the adapter 300 which - itself - acts as an interface with the articulated arm 600 of the wiping system 700 with which the wiper blade 500 is intended to be adapted. To this end, the adapter 300 is mechanically coupled to the connector 200. More particularly, the adapter 300 is pivotally mounted on the connector 200.

For this purpose, the connector 200 comprises a rotation axis 240 intended to collaborate with the rotation axis 310 of the adapter 300. As visible in FIGURE 2B, the rotation axis 240 of the connector 200 is materialized by :

A cylindrical housing 210 collaborating with the cylindrical sleeve 390 of the adapter 300; and

A cylindrical sleeve 220 collaborating with the cylindrical housing 380 of the adapter 300.

Thus, when the adapter 300 is pivotally mounted on the connector 200, then the cylindrical sleeve 390 of the adapter 300 is introduced into the cylindrical housing 210 of the connector; and the cylindrical housing 380 of the adapter 300 receives the cylindrical sleeve 220 of the connector 200. This advantageous configuration makes it possible to make the axes of rotation 310, 240 of the adapter 300 and the connector 200 coaxial. Consequently, this results in mounting pivoting of the adapter 300 on the connector 200, with respect to their axes of rotation 310, 240.

Referring to FIGURES 3A to 3D, there are shown two embodiments of a wiping system 700 according to the third aspect of the invention. In FIGURES 3B and 3C, the yoke 650 of the arm 600 is shown in transparency in order to facilitate understanding of the invention.

Such a wiping system 700 comprises at least one arm 600 detachably fixed to the adapter 300 of the wiper blade 500 according to the second aspect of the invention and as described with reference to FIGURES 2 Each arm 600 comprises a yoke 650 inside which the adapter 300 is housed and mechanically coupled by engagement of complementary shapes. In addition, each arm 600 is rotated by an electric motor, not shown in FIGURES 3.

The yoke 650 of the arm 600 comprises two lateral edges 651 connected to each other by an upper edge 652. As can be seen in FIGURES 3B, 3C and 3D, the yoke 650 is open at a lower vertical end, c ' that is to say at a distal end of the lateral edges 651 relative to the upper edge 652 of the yoke 650.

The yoke 650 is also open at one of its longitudinal ends, so as to allow the introduction by translation of the adapter 300 inside the yoke 650. This open longitudinal end of the yoke 650 is provided on the side of a pivot point of the arm 600. The other longitudinal end of the yoke 650 is closed by a closing edge 654, against which the adapter 300 can come to bear in the event of breakage or malfunction of the coupling member 360.

At these distal ends, each lateral edge 651 comprises a folded edge 655 which extends laterally towards the inside of the yoke 650. Each folded edge 655 of the yoke 650 thus forms a sidewalk which extends laterally towards the inside of the yoke 650 with respect to the associated lateral edge 651, relative to the transverse axis X.

When the adapter 300 is mounted in the yoke 650, the lower bearing face 323, 333 of at least one of the side walls 320, 330 - and preferably of the two side walls 320, 330 - of the adapter 300 bears against the folded edge 655 of the yoke and located opposite.

Thus, according to the invention, the folded edge of the yoke 655 is in abutment against the lower bearing face 323, 333 of the corresponding side wall 320, 330 of the adapter 300 at the axis of rotation 310 of said adapter 300. In other words, in line with the axis of rotation 310, the adapter 300 is in vertical support against the folded edge of the yoke 650, relative to the vertical axis Z.

Additionally, as shown in FIGURE 3D, the outer faces 324, 334 of the side walls 320, 330 of the adapter 300 are in lateral support against the side edges 651 of the yoke 650. This configuration thus makes it possible to maintain well the adapter 300 in the yoke 650, and thus guarantee a good mechanical coupling between the wiper blade 500 and the arm 600 of the wiping system 700.

In addition, when the adapter 300 is housed in the yoke 650 in its functional configuration, that is to say that in which the wiping system 700 can be activated on a glass wall of a motor vehicle , then the coupling member 360 of the adapter 300 collaborates with an opening 653 formed on the yoke 650. This configuration makes it possible to block the wiper blade 500 on the arm 600, more particularly preventing relative longitudinal movement between the adapter 300 and the yoke 650. In the example illustrated in FIGURES 3A to 3C, the opening 653 is located on the upper edge 652 of the yoke 650. In addition, the opening 653 of the yoke 650 has a shape complementary to that of the button 361 of the coupling member 360 of the adapter 300, in order to allow engagement of the button 361 in the opening 653 when the adapter 300 reaches its functional configuration.

The yoke 650 of the arm 600 is closed at its longitudinal end by the closing edge 654 which extends laterally between the two lateral edges 651 of the yoke 650. The closing edge 654 is for example made of material with the upper edge 652 and with the lateral edges 651. Vertically, the closing edge 654 is open at a lower vertical end, similarly to the lateral edges 651 of the yoke 650. On the other hand, the closing edge 654 does not carry no folded edges similar to those of the side edges 651.

The closing edge 654 at least partially delimits a cavity 656 at the first longitudinal ends 321, 331 of the connector 300, when the adapter 300 is housed in the yoke 650 in its functional configuration. Thus, in the event of a malfunction of the coupling member 360 of the adapter 300 with the corresponding opening 653 of the yoke 650, then the connector 300 would be propelled in the direction of the closing edge 654 of the yoke 650, and the means securing device 100 - formed by the first longitudinal ends 321, 331 of the walls 320, 330, 340 of the adapter 300 - would then come into abutment against the closing edge 654, thus preventing the wiper blade 500 from being propelled out of the yoke 650. The advantageously planar shape of the first longitudinal ends 321, 331 of the side walls 320, 330 of the adapter 300 thus makes it possible to accommodate the adapter in a yoke 650 closed longitudinally at the front by its edge of closure 654, while allowing the security means 100 to abut against the closing edge 654 in the event of a malfunction.

FIGURES 3B and 3C illustrate two alternative embodiments of the connector 200 of the wiper blade 500 according to the second aspect of the invention:

In FIGURE 3B, the yoke 650 of the arm 600 further comprises a tongue 657 which extends longitudinally in the direction of the connector 200. The tongue 657 is located at a distal end of the closing edge 654 relative to the upper edge 652 of the yoke 650. In addition, a front face of the connector 200 is formed by two lateral surfaces 230 spaced laterally and which each extend against one of the side walls 320, 330 of the adapter 300, inside the housing 350 of said adapter 300. The lateral bearing surfaces 230 of the connector 200 are laterally spaced from one another in order to allow the partial insertion of a terminal end 658 of the tongue between the lateral bearing surfaces 230 of the connector 200;

In LIGURE 3C, a front face of the connector 200 is formed by a bearing surface 250 which extends laterally between the side walls 320, 330 of the adapter 300, inside the housing 350 of said adapter 300. The scope 250 thus forms, at its longitudinal end situated opposite the cavity 656 formed by the closing edge 654 of the yoke 650 of the arm 600, a single flat surface.

In summary, the invention relates in particular to an adapter 300 for fixing a wiper blade 500 on an arm 600 of a wiping system 700, the adapter 300 being pivotally mounted on a connector 200 of the wiper blade 500. The adapter 300 comprises two side walls 320, 330 connected together by an upper wall 340 and forming between them a housing 350 for the connector 200. At a distal end of the walls lateral 320, 330 relative to the upper wall 340, the connector comprises a lower bearing face 323, 333 intended to collaborate with a folded edge 655 of the yoke 650. According to the invention, at each side wall 320, 330, the lower bearing face 323, 333 of the adapter 300 extends at least in part at the level of a zone situated perpendicular to an axis of rotation 310 of the adapter 300 relative to the connector 200.

Of course, the invention is not limited to the examples which have just been described and numerous modifications can be made to these examples without departing from the scope of the invention. In particular, the different characteristics, forms, variants and embodiments of the invention can be associated with one another in various combinations insofar as they are not incompatible or mutually exclusive of each other. In particular, all the variants and embodiments described above can be combined with one another.
