Description

Adapter for a motor vehicle windscreen wiper blade
Technical Field
The present invention relates to the field of windscreen wiper blades for motor vehicle windows, and more particularly to an adapter for fastening a windscreen wiper blade to an arm of a wiper system.
Background
In the automotive field, wiper systems may scrape glazing panels of motor vehicles. Typically, such wiper systems include one or more wiper blades that are hinged such that they can move against the glazing panel. Each windscreen wiper blade comprises a structure supporting a wiper strip intended to be placed in contact with the glazing panel, so that it can remove water from the glazing panel. In addition, each windshield wiper blade includes a connector rigidly connected to the structure and an adapter pivotally mounted on the connector to allow the arms of the wiper system to be removably secured to the adapter of the windshield wiper blade.
The adapter of the windscreen wiper blade engages in the yoke of the arm in a known manner by a longitudinal translational movement relative to the extension direction of the yoke. To this end, the yoke comprises two folded edges which, when the adapter is assembled, can guide the adapter longitudinally and hold the adapter in the yoke in its functional configuration with the wiper system.
There are many types of adapters depending on the different types of windscreen wiper blades and different types of arms. Generally, known adapters include: (i) Two lateral walls spaced apart from each other and connected to each other by an upper wall, each lateral wall comprising a lower bearing surface allowing the lateral wall to bear against one of the folded edges of the yoke of the arm; and (ii) a member for coupling the adapter to the yoke.
In particular, in DE 10 2008 011 449 A1, due to the curved shape of the yoke of the articulated arm, which prevents the adapter from being inserted from one of its longitudinal ends, the adapter is first inserted into the yoke in a translational movement, perpendicular to the extension direction of the yoke, between two spaced apart sections of each folded edge, towards the recess of the yoke, into the central region of the yoke.
This type of assembly complicates the geometry of the adapter, wherein each lateral wall of the adapter comprises two end portions that are longitudinally spaced apart from each other and separated by a central recess extending from the upper wall. The central recess is located longitudinally on the rotational axis of the adapter. This configuration allows the adapter to be inserted toward the recess of the yoke by placing one of the two sections of the folded edge of the yoke in the central recess of the adapter. At the end of this translation towards the recess of the yoke, the adapter is then engaged longitudinally in the yoke until it is in its functional configuration with the arm. In this functional configuration, each section of the folded edge of the yoke engages with each end portion positioned facing the lateral wall of the adapter; the folded edge of the yoke does not engage the adapter in the central recess, which may therefore make the coupling of the adapter in the yoke of the arm unstable and/or incorrect.
In WO 2010/034445 A1, one longitudinal end of the adapter comprises a projection extending in protruding relation to the lateral edge of the adapter. During its assembly, the adapter engages in the yoke of the arm at the front longitudinal end of the yoke until it is in its functional configuration with the arm. Then, in this functional configuration, the protrusion extends from the longitudinal end of the yoke; it does not interact with the yoke of the arm, but with the closing cap attached to the yoke of the arm.
In order to fix the adapter in the yoke in case of failure of the coupling member of the adapter, one of the folded edges of the yoke comprises a lug which interacts with one of the lateral walls of the adapter at a distal end with respect to the upper wall. This configuration makes it possible to retain the adapter when the coupling member of the adapter is pulled out, thus preventing the windshield wiper blade from being ejected from the arm. A disadvantage is the complexity of implementing the lugs on the folded edges of the yoke, resulting in increased manufacturing costs. In addition, this configuration also causes additional surfaces to be provided on the adapter to interact with the lugs to retain the adapter.
The object of the present invention is to overcome at least to a large extent the above-mentioned problems and to create further advantages by proposing a new adapter for fastening a windscreen wiper blade to a wiper system arm.
It is a further object of the invention to allow for easier assembly of such an adapter by the rear longitudinal end of the yoke of the arm.
It is a further object of the invention to secure the adapter in the yoke of the arm in case of failure.
It is a further object of the invention to simplify the manufacture of such an adapter and to reduce its manufacturing costs.
Disclosure of Invention
According to a first aspect of the present invention, at least one of the above objects is achieved by an adapter for fastening a windscreen wiper blade to an arm of a wiper system, the adapter being configured to be pivotally mounted on a connector of the windscreen wiper blade about an axis of rotation, the adapter comprising: (i) Two lateral walls spaced apart from each other and connected to each other by an upper wall, each lateral wall of the adapter comprising an underside for bearing on a folded edge of a yoke of the arm; and (ii) a member for coupling the adapter to the yoke. According to the invention, the first longitudinal end of the adapter forms a fixing means configured to retain the adapter in the yoke of the arm when the coupling member is uncoupled from the yoke, and the lower bearing surface of at least one of the lateral walls extends in alignment with the rotation axis.
In other words, the means for fixing the adapter are configured such that when the coupling members are uncoupled from the yokes they can bear against the longitudinal ends of the yokes of the arms, and preferably against the front longitudinal ends of the yokes. Since the adapter according to the first aspect of the invention is intended in particular to be assembled on an associated wiper system by translation from the rear longitudinal face of the arm, the yoke of such an arm is advantageously closed at the front, i.e. at the longitudinal end opposite to the end through which the adapter is inserted into the yoke.
For this purpose, at the first and second longitudinal ends of the adapter, the longitudinal ends of the upper wall extend at most longitudinally up to the respective longitudinal ends of the lateral walls. The upper wall of the adapter according to the invention does not comprise a projection extending protruding relative to the lateral wall, and the interaction between the securing means and the yoke of the arm in case of failure of the coupling member occurs at the longitudinal end of the lateral wall of the adapter according to the first aspect of the invention.
When the securing means act on an untimely uncoupling of the adapter from the yoke of the arm, which is caused by an accidental disconnection, malfunction or breakage of the coupling member during operation of the wiper system. In this way, when the coupling member of the adapter is uncoupled from the yoke of the arm during operation of the wiper system, the securing means of the adapter are pushed towards the front longitudinal end of the yoke against the closed front longitudinal face of the yoke by centrifugal forces associated with the rotational movement of the windscreen wiper arm on the glazing surface. The adapter is thus retained in the yoke and in the event of a failure the windscreen wiper blade is not disconnected from the arm.
When the adapter is engaged in the yoke of the arm and in the functional configuration of the wiper system, the lower bearing surface corresponds to the surface of the adapter bearing on the folded edge of the yoke of the arm with which the adapter is intended to interact.
More specifically, the lower bearing surface of the adapter extends in alignment with the lateral ends of the rotation axis with respect to the vertical axis of the adapter. In other words, at the lateral end of the rotation axis, there is a vertical straight line perpendicular to the rotation axis, which intersects the lower bearing surface of the adapter.
According to a first aspect of the invention, the invention is intended for both the original equipment market and the replacement market for a wiper system and/or a windscreen wiper blade and/or an adapter for such a windscreen wiper blade.
In the context of the present invention, the following adjectives are defined with respect to the adapter according to the first aspect of the present invention:
the adjective "longitudinal" refers to the direction of extension of the adapter along its maximum length. When the adapter is assembled on a windscreen wiper blade, the longitudinal direction refers to the axis formed by the wiper strip. By extension, the longitudinal direction refers to a direction parallel or substantially parallel to the maximum length of the wiper blade strip, and the adjectives "front" and "rear" refer to relative positions along the longitudinal axis;
The adjective "transverse" or "lateral" refers to a direction extending perpendicular to the longitudinal direction, more specifically to a direction perpendicular to both lateral edges of the cover of the adapter;
the adjective "vertical" refers to a direction perpendicular to both the longitudinal direction and the transverse direction. For example, the vertical direction refers in particular to the relative position of the wiper blade strip with respect to the adapter according to the first aspect of the invention. By extension, the adjectives "lower" and "upper" refer to relative positions along a vertical axis.
The adapter according to the first aspect of the invention may advantageously comprise at least one of the following improvements, and the technical features forming these improvements may be considered individually or in combination:
the adapter according to the first aspect of the invention has a U-shaped transverse cross-section. In other words, the upper wall separates the two lateral walls of the adapter in lateral direction. In particular, the lateral walls are laterally spaced apart from each other, thus defining with the upper wall a recess for a connector of a windscreen wiper blade;
to facilitate insertion of the adapter according to the first aspect of the invention into the yoke of the arm, the adapter is intended to interact with the yoke, the lateral walls of the adapter being parallel to each other. More specifically, the lateral wall is perpendicular to the upper wall of the adapter according to the first aspect of the invention;
The upper wall and/or the lateral wall of the adapter according to the first aspect of the invention is flat. This advantageous configuration makes it possible to facilitate the insertion of the adapter according to the first aspect of the invention into the yoke of the arm with which the adapter is intended to interact. In particular, the upper face of the upper wall of the adapter is flat to facilitate its interaction with the yoke of the arm and/or the lower face of the upper wall of the adapter is flat to facilitate the insertion of the connector of the windscreen wiper blade into the adapter. Similarly, the outer face of the lateral wall is advantageously flat to facilitate interaction of the lateral wall with the yoke of the arm, and/or the underside of the lateral wall is advantageously flat to facilitate insertion of the connector of the windscreen wiper blade into the adapter;
the lower bearing surfaces of the two lateral walls of the adapter according to the first aspect of the invention extend in alignment with the axis of rotation, so as to improve the coupling of the adapter with the yoke of the arm with which the adapter is intended to interact;
at least one of the lateral walls, preferably the lower bearing surfaces of both lateral walls, of the adapter according to the first aspect of the invention is symmetrical with respect to the rotational axis of the adapter with respect to the connector with which the adapter is intended to interact;
At least one of the lateral walls, preferably the lower bearing surfaces of both lateral walls, of the adapter according to the first aspect of the invention extends towards the first longitudinal end (preferably front) and/or towards the second longitudinal end (preferably rear) of the adapter. Advantageously, the lower bearing surface extends up to the first longitudinal end and/or the second longitudinal end of the adapter according to the first aspect of the invention. This advantageous configuration allows the contact surface between the adapter and the yoke of the arm to be maximized when the adapter is mounted on the arm, thereby improving the retention of the windscreen wiper blade in the yoke of the arm;
at least one of the lateral walls of the adapter according to the first aspect of the invention, preferably the lower bearing surfaces of both lateral walls, are parallel to the axis of rotation. Additionally or alternatively, the lower bearing surface of the adapter according to the first aspect of the invention is perpendicular to one of the lateral walls of the adapter. Additionally or alternatively, the lower bearing surface of the adapter according to the first aspect of the invention is parallel to the upper wall of the adapter;
at the first and second longitudinal ends of the adapter, the longitudinal ends of the upper wall extend longitudinally at most up to the corresponding longitudinal ends of the lateral walls. This advantageous configuration at the same time makes it possible to facilitate the interaction of the adapter according to the first aspect of the invention with the longitudinal end of the yoke of the arm into which the adapter is intended to be inserted; the upper wall of the adapter does not extend longitudinally protruding relative to the lateral walls of the adapter. This configuration is particularly suitable for an arm yoke with a closed front longitudinal end, requiring insertion of an adapter through the rear longitudinal end;
At least one, preferably both, of the lateral walls of the adapter according to the first aspect of the invention have a lower bearing surface formed by the distal end of the lateral wall with respect to the upper wall of the adapter. In other words, the lower bearing surface of the adapter is formed by the underside of the corresponding lateral wall. Advantageously, the distal ends of the lateral walls of the adapter are coplanar. In other words, the underside of the lateral wall is located at the same distance from the upper wall of the adapter. This advantageously symmetrical configuration makes it possible to facilitate the insertion of the adapter into the yoke of the arm with which it is intended to interact and to reduce the manufacturing costs of the adapter and of the corresponding yoke;
on the first lateral wall of the adapter, the rotation axis is formed by a cylindrical recess formed from the inner face of the first lateral wall of the adapter. The rotation axis is then defined by the central axis of the cylindrical recess. The cylindrical recess extends from an inner face of the first lateral wall of the adapter according to the first aspect of the invention towards an outer face of the first lateral wall. Advantageously, the cylindrical recess emerges onto the outside of the first cylindrical wall. In other words, the cylindrical recess advantageously passes through the first lateral wall of the adapter. This advantageous configuration makes it possible in particular to reduce the manufacturing costs of the adapter;
The cylindrical recess is located between the upper wall of the adapter according to the first aspect of the invention and the lower bearing surface of the first lateral wall in the vertical direction;
the cylindrical recess is delimited by a peripheral contour. The peripheral profile is advantageously polygonal. In addition, the peripheral profile is advantageously symmetrical about the central axis of the cylindrical recess to facilitate interaction of the adapter and a connector of the windscreen wiper blade on which the adapter is intended to be pivotally mounted. As a non-limiting example, the peripheral profile defining the cylindrical recess is preferably square;
the lower bearing surface of the first lateral wall of the adapter extends at least in alignment with the cylindrical recess. In other words, the lower bearing surface of the first lateral wall extends longitudinally at least between the longitudinal sides of the cylindrical recess defined longitudinally. In other words, the lower bearing surface of the first lateral wall of the adapter according to the first aspect of the invention extends longitudinally at least between the walls of the cylindrical recess delimited by the peripheral profile;
on the second lateral wall of the adapter, the rotation axis is formed by a cylindrical sleeve extending protruding from the inner face of the second lateral wall of the adapter, which cylindrical sleeve is coaxial with the cylindrical recess. Thus, the rotation axis of the adapter according to the first aspect of the invention is not formed on said adapter in the same shape between the two lateral walls of the adapter; on the second lateral wall, the rotation axis is not formed by a cylindrical recess of the first lateral wall, but by a cylindrical sleeve. This advantageous configuration makes it possible to form a rotary support, thereby contributing to the stability of the pivotable mounting of the adapter according to the first aspect of the invention on the connector of the windscreen wiper blade with which the adapter is intended to interact;
The cylindrical sleeve comprises at least two diametrically opposed flat portions;
the cylindrical sleeve comprises a through opening delimited by a circular contour, which is coaxial with the cylindrical sleeve. The through opening passes laterally from one side of the second lateral wall of the adapter according to the first aspect of the invention to the other side, a cylindrical sleeve being formed on the second lateral wall. In addition, the through opening is advantageously aligned longitudinally and/or vertically with a cylindrical recess formed in the first lateral wall of the adapter. In other words, in the lateral plane of the adapter according to the first aspect of the invention, the through opening formed in the second lateral wall is located inside the cylindrical recess formed in the first lateral wall;
the lower bearing surface of the second lateral wall of the adapter extends at least in alignment with the cylindrical sleeve. In other words, the lower bearing surface of the second lateral wall extends longitudinally at least between the sides forming the cylindrical sleeve;
the coupling member is located on the upper wall of the adapter according to the first aspect of the invention. By being able to couple the adapter to the upper face of the yoke, this advantageous configuration makes it possible to facilitate the interaction of the adapter according to the first aspect of the invention with the yoke of the arm into which the adapter is inserted;
The coupling member includes a button at one end of the bearing surface. This advantageous configuration makes it possible to selectively activate or deactivate the coupling member in order to couple or decouple the adapter and the yoke, respectively. To this end, the coupling member is advantageously connected to the upper wall of the adapter by a flexible hinge configured to allow elastic deformation of the bearing surface of the coupling member with respect to the upper wall of the adapter;
the button of the coupling member extends beyond the longitudinal end of the adapter. In other words, the coupling member, in particular the bearing surface thereof, extends longitudinally beyond the longitudinal end of the lateral wall of the adapter. This advantageous configuration makes it possible to lengthen the bearing surface of the coupling member and as a result increase the lever arm effect of the push button located at the end of the bearing surface. Alternatively, the button of the coupling member is longitudinally located between the first and second longitudinal ends of the lateral wall of the adapter along a longitudinal axis of the adapter extending from the rear towards the front of the adapter;
the adapter according to the first aspect of the invention is made of plastic to reduce manufacturing costs. As a non-limiting example, the adapter is obtained by molding.
According to a second aspect of the present invention, there is provided a motor vehicle windscreen wiper blade comprising: a structure supporting a wiper strip; a connector rigidly secured to the structure; and an adapter according to the first aspect of the invention or according to any modification thereof, the adapter being pivotally mounted on the connector.
The adapter according to the first aspect of the invention is thus coupled to the connector of the windscreen wiper blade by its axis of rotation. In other words, the connector comprises an additional axis of rotation which interacts with the axis of rotation of the adapter according to the first aspect of the invention and as described previously by any of its modifications. As a result, the adapter is rigidly connected to the connector and is free to pivot about its axis of rotation to keep the wiper blade pressed against the glazing surface of the motor vehicle.
In the context of the present invention according to its second aspect and according to the first variant embodiment, the structure supporting the wiper strip is of the type comprising a single spline (rib). This first variant embodiment is called a single spline. In this case, the spline is received in a channel of the plastic support to which the connector is attached, and the channel further comprises a claw for attaching a bead of wiper blade rubber. The connector may also be directly attached to the spline and the bead of wiper strip may be bonded to the face of the single spline.
Alternatively, according to a second variant embodiment, the structure supporting the wiper strip is of the type comprising two splines laterally distributed on both sides of the back of the wiper strip. This second variant embodiment is called a bi-spline.
According to a third aspect of the present invention, a wiper system is presented comprising at least one windscreen wiper blade according to the second aspect of the present invention detachably fastened to an arm via an adapter, the arm comprising a yoke mechanically coupled to the adapter by a complementary shaped engagement. Here, the arm is an arm for rotating a windshield wiper blade, which is pivotally mounted on a pivot point formed by the shaft of a drive motor.
The wiper blade system according to the third aspect of the present invention may advantageously comprise at least one of the following improvements, and the technical features forming these improvements may be considered individually or in combination:
the arm of the wiper system according to the third aspect of the present invention is rotated by an electric motor;
the yoke of the arm of the wiper system according to the third aspect of the invention comprises two lateral edges, each lateral edge comprising a folded edge extending laterally towards the interior of the yoke, the lower bearing surface of the adapter bearing against the folded edge positioned facing the lower bearing surface. The folded edge of each lateral edge of the yoke is located at the free end of the lateral edge. The two lateral edges of the yoke form a concave space therebetween into which the adapter can be inserted by translation along the longitudinal extension direction of the yoke. The folded edge of the yoke against which the adapter according to the first aspect of the invention is supported thus makes it possible to guide the adapter during its longitudinal insertion into the yoke of the arm. In addition, the folded edges of the yoke help to hold the adapter in place in the yoke of the arm when the adapter reaches its functional configuration with the arm;
The lateral wall of the adapter bears against the lateral edge of the yoke of the arm. In particular, the lateral wall of the adapter according to the first aspect of the invention supports laterally against the lateral edge of the yoke of the arm during insertion of the adapter into the yoke and/or in the functional configuration of the adapter in the yoke;
the yoke of the arm comprises a closing edge extending laterally between two lateral edges at one longitudinal end of the yoke. In other words, the yoke of the arm of the wiper system according to the third aspect of the invention is especially a yoke of the type that is open at the rear, i.e. towards the pivot point of the arm, which allows the adapter to be inserted into the yoke only through its rear longitudinal end. In addition, the closed edge of the yoke allows the adapter to be retained in combination with the means for securing the adapter according to the first aspect of the invention when the means for coupling the adapter to the yoke is disengaged from the yoke during operation of the wiper system; the fixing means then bear against the closed end of the yoke in the longitudinal direction, thus preventing the windscreen wiper blade from being pushed out of the arm;
the yoke includes an upper edge connecting the two lateral edges, the upper edge including an opening configured to allow engagement of the coupling member when the adapter is coupled to the arm. Preferably, the opening formed in the upper edge of the yoke of the arm is configured to allow engagement of the button of the coupling member when the adapter is coupled to the arm.
Various embodiments of the invention combining the different optional features set forth herein in all possible combinations are contemplated.

Referring to fig. 1A to 1F, an exemplary embodiment of an adapter 300 according to the first aspect of the present invention is first described.
Such an adapter 300 includes:
two lateral walls 320, 330 spaced apart from each other and connected to each other by an upper wall 340, such that the adapter 300 has a U-shaped section in a transversal plane formed by a transversal axis Y and a vertical axis Z, as can be seen in particular in fig. 1E;

In the example illustrated in fig. 1, the lateral walls 320, 330 are parallel to each other and perpendicular to the upper wall 340 of the adapter 300. Alternatively, depending on the shape of the yoke 650 intended to interact with the adapter 300, the lateral walls 320, 330 may form an angle with the upper wall 340 of greater than 90 °.
Each lateral wall 320, 330 of the adapter 300 includes a chamfer 327, 337 at its vertical upper end to facilitate its insertion into a yoke 650 of the arm 600 into which the adapter 300 is intended to be inserted. In other words, the upper wall 340 of the adapter 300 includes a chamfer 327, 337 at each lateral end thereof, particularly in the transverse plane illustrated in fig. 1E. The chamfer is advantageously oriented at 45 ° with respect to the upper wall 340 of the adapter 300. In addition, the chamfer 327, 337 of each lateral wall 320, 330 of the adapter 300 extends longitudinally between the two longitudinal ends 321, 331, 322, 332 of the lateral wall.
Laterally, the first lateral wall 320 of the adapter 300 is delimited by an outer face 324 and an inner face 325. The inner face 325 of the first lateral wall 320 is positioned to face the second lateral wall 330 of the adapter 300. In the example illustrated in fig. 1A, the inner face 325 and the outer face 324 of the first lateral wall 320 are advantageously flat and parallel to each other.
Longitudinally, the first lateral wall 320 of the adapter 300 is delimited by a first longitudinal end 321 at the front of the adapter 300 and a second longitudinal end 322 at the rear of the adapter 300 with respect to the longitudinal axis X. The first 321 and second 322 longitudinal ends of the first side wall 320 are advantageously flat and parallel to each other. The first lateral wall 320 further includes a vertical chamfer defining an outer face 324 of each longitudinal end 321, 322 of the first lateral wall.
In the vertical direction, the first lateral wall 320 of the adapter 300 is delimited by the upper wall 340 of the adapter 300 and by the flat lower face forming the lower bearing faces 323, 333 of the adapter 300, which are intended to interact with the folded edges 655 of the yokes 650 of the arms 600 with which the adapter 300 is intended to interact.
To facilitate insertion of the adapter 300 into the yoke 650 of the arm 600 with which the adapter 300 is intended to interact, the first longitudinal end 321 of the first lateral wall 320 comprises on its lower bearing surface 323 a chamfer 328 defining an edge inclined towards the second lateral wall 330.
The first lateral wall 320 of the adapter 300 thus has a generally parallelepiped shape extending vertically below the upper wall 340 of the adapter 300 with respect to the vertical axis Z.
As can be seen in particular in fig. 1C, 1D and 1F, the first lateral wall 320 further comprises two oblong openings 326a, 326b extending longitudinally in the first lateral wall 320. The oblong openings 326a, 326b of the first lateral wall 320 are through openings along the vertical axis Z; these oblong openings appear simultaneously to the upper wall 340 and the lower bearing surface 323 of the first lateral wall 320. Laterally, oblong openings 326a, 326b are located between the outer face 324 and the inner face 325 of the first lateral wall 320, preferably such that they are centered with respect to the transverse axis Y of the adapter 300.
Similarly, the second lateral wall 330 of the adapter 300 is laterally bounded by an outer face 334 and an inner face 335. The inner face 335 of the second lateral wall 330 is positioned to face the first lateral wall 320 of the adapter 300. In the example illustrated in fig. 1A, the inner face 335 and the outer face 334 of the second lateral wall 330 are advantageously flat and parallel to each other.
Longitudinally, the second lateral wall 330 of the adapter 300 is delimited by a first longitudinal end 331 at the front of the adapter 300 and a second longitudinal end 332 at the rear of the adapter 300 with respect to the longitudinal axis X. The first and second longitudinal ends 331, 332 of the second lateral wall 330 are advantageously flat and parallel to each other. The second lateral wall 330 further includes a vertical chamfer defining an outer face 334 of each longitudinal end 331, 332 of the second lateral wall.
Advantageously and in particular as can be seen in fig. 1C and 1D, the first and second longitudinal ends 321, 322 of the first lateral wall 320 and the first and second longitudinal ends 331, 332 of the second lateral wall 330 are parallel to each other. More preferably, the first longitudinal end 321 of the first lateral wall 320 and the first longitudinal end 331 of the second lateral wall 330 are coplanar, and the second longitudinal end 322 of the first lateral wall 320 and the second longitudinal end 332 of the second lateral wall 330 are coplanar.
In the vertical direction, the second lateral wall 330 of the adapter 300 is delimited by the upper wall 340 of the adapter 300 and by the flat lower face forming the lower bearing faces 323, 333 of the adapter 300, which are intended to interact with the folded edges 655 of the yokes 650 of the arms 600 with which the adapter 300 is intended to interact. As can be seen in fig. 1E, the planar lower surfaces of each lateral wall 320, 330 of the adapter 300 together form a single planar lower bearing surface 323, 333. In other words, the planar lower surface of each lateral wall 320, 330 of the adapter 300 is advantageously coplanar.
To facilitate insertion of the adapter 300 into the yoke 650 of the arm 600 with which the adapter 300 is intended to interact, the first longitudinal end 321 of the second lateral wall 330 comprises on its lower bearing surface 333 a chamfer 338 defining an edge inclined towards the first lateral wall 320.
Accordingly, the second lateral wall 330 of the adapter 300 has a generally parallelepiped shape extending vertically below the upper wall 340 of the adapter 300 with respect to the vertical axis Z.
As can be seen in particular in fig. 1C, 1D and 1F, the second lateral wall 330 further comprises two oblong openings 336a, 336b extending longitudinally in the second lateral wall 330. The oblong openings 336a, 336b of the second lateral wall 330 are through openings along the vertical axis Z; these oblong openings appear simultaneously to the upper wall 340 and the lower bearing surface 333 of the second lateral wall 330. Laterally, oblong openings 336a, 336b are located between outer face 334 and inner face 335 of second lateral wall 330, preferably such that they are centered with respect to transverse axis Y of adapter 300.
As can be seen in fig. 1D, 1E and 1F, the lateral walls 320, 330 and the upper wall 340 of the adapter 300 together define a recess 350 that allows for insertion of the connector 200 of the windscreen wiper blade 500 when the adapter 300 is pivotally mounted on said connector 200. The recess 350 thus occurs at the first longitudinal end 321, 331 of the lateral walls 320, 330 of the adapter 300, preferably at the front of the adapter 300.
In the exemplary embodiment illustrated in fig. 1, the recess 350 of the adapter 300 is also present at the second longitudinal ends 322, 332 of the lateral walls 320, 330 of the adapter 300, preferably at the rear of the adapter 300. In other words, the recess 350 passes longitudinally along the longitudinal axis X of the adapter 300 from one side of the adapter to the other.
With respect to the lateral axis Y of the adapter 300, the recess 350 is defined by the inner faces 325, 335 of the lateral walls 320, 330 of the adapter 300.
With respect to the vertical axis Z of the adapter 300, the recess 350 is delimited on the upper side by the underside of the upper wall 340 of the adapter 300; in a vertical direction opposite to the upper wall 340, the recess 350 is not delimited, but emerges onto the lower bearing surfaces 323, 333 of the adapter 300.
As a result, as can be seen in particular in fig. 1E, in the transverse plane formed by the transverse axis Y and the vertical axis Z, the recess 350 has a generally rectangular shape between the lateral walls 320, 330 and the upper wall 340 of the adapter 300.
As can be seen in fig. 1C, 1D and 1F, the upper wall 340 of the adapter 300 comprises a through opening 370 at the first longitudinal ends 321, 331 of the lateral walls 320, 330. The through opening 370 is formed from above the upper wall 340 of the adapter 300 up to the lower face of said upper wall 340 towards the lower face 323, 333 of the adapter 300, which lower face bears against the folded edge 655 of the yoke 650 of the arm 600 with which the adapter 300 is intended to interact. Thus, the through opening 370 takes the form of a recess through the upper wall 340.
The through opening 370 of the upper wall 340 is longitudinally present at the first longitudinal ends 321, 331 of the lateral walls 320, 330 of the adapter 300 with respect to the longitudinal axis X of the adapter 300. In other words, in the longitudinal direction, the through opening 370 is delimited by an open contour 371 at the longitudinal end 341 of the upper wall 340. Thus, in the example illustrated in fig. 1C, 1D and 1F, the first longitudinal end 341 of the upper wall 340 extends longitudinally at most at the first longitudinal end of the adapter 300 up to the corresponding first longitudinal end 321, 331 of the lateral wall 320, 330; and the second longitudinal end 342 of the upper wall 340 extends longitudinally at most at the second longitudinal end of the adapter 300 up to the corresponding second longitudinal end 322, 332 of the lateral wall 320, 330. As a result, the upper wall 340 of the adapter 300 according to the invention does not comprise a projection extending protruding with respect to the lateral walls 320, 330.
Laterally, the through opening 370 of the upper wall 340 is delimited by the inner faces 325, 335 of the lateral walls 320, 330 of the adapter 300. The through opening 370 of the upper wall 340 of the adapter 300 thus has a generally rectangular shape.
In the example illustrated in fig. 1, an adapter 300 according to the first aspect of the invention is configured to be pivotally mounted about an axis of rotation 310 on a connector 200 of a windscreen wiper blade, on which the adapter is intended to be mounted. To this end, the adapter 300 comprises means configured to define an axis of rotation 310:
On the first lateral wall 320, the rotation axis 310 is formed by a cylindrical recess 380, which is formed from the inner face 325 of the first lateral wall 320 and which laterally emerges on the outer face 324 of the first lateral wall 320. More specifically, the rotation axis 310 is located at the center of the cylindrical recess 380, and the rotation axis 310 is coaxial with the cylindrical recess 380;
on the second lateral wall 330, the rotation axis 310 is formed by a cylindrical sleeve 390 extending protruding from an inner face 335 of the second lateral wall 330. More specifically, the rotational axis 310 is located at the center of the cylindrical sleeve 390, and the rotational axis 310 is coaxial with the cylindrical sleeve 390. In addition, the cylindrical sleeve 390 comprises a through opening 395 delimited by a circular contour 396, the through opening 395 being coaxial with the cylindrical sleeve 390. The through opening 395 of the cylindrical sleeve 390 passes laterally from one side of the second lateral wall 330 of the adapter 300 to the other. In addition, cylindrical sleeve 390 is coaxial with cylindrical recess 380.
According to a first aspect of the invention, and as can be seen in particular in fig. 1B and 1F, the lower bearing surface 323 of the first lateral wall 320 of the adapter 300 extends at least in alignment with the cylindrical recess 380. In other words, the lower bearing surface 323 of the first lateral wall 320 longitudinally extends between the longitudinal sides 382a, 382b of the cylindrical recess 380. The cylindrical recess 380 is delimited by a peripheral contour 381 comprising two longitudinal sides 382a, 382 b. The peripheral profile 381 is advantageously polygonal and in the example illustrated in fig. 1 is preferably square.
More generally, the lower bearing surface 323 of the first lateral wall 320 of the adapter 300 is located at least partially between the two longitudinal sides 382a, 382b of the cylindrical recess 380. As a result, the lower bearing surface 323 of the first lateral wall 320 extends longitudinally beyond the longitudinal sides 382a, 382b of the cylindrical recess 380 toward the first longitudinal end 321 and/or the second longitudinal end 322 of the first lateral wall 320 of the adapter 300. Preferably, the lower bearing surface 323 of the first lateral wall 320 extends longitudinally symmetrically about the rotation axis 310. More preferably, and as can be seen in fig. 1, the lower bearing surface 323 of the first lateral wall 320 extends longitudinally along the entire first lateral wall 320, i.e. up to the first longitudinal end 321 and/or the second longitudinal end 322 of the first lateral wall 320.
As can be seen in fig. 1A, 1D and 1E, the lower bearing surface 333 of the second lateral wall 330 of the adapter 300 extends at least in alignment with the cylindrical sleeve 390. In other words, the lower bearing surface 333 of the second lateral wall 330 extends longitudinally between the circular profiles 396 defining the through opening 395. More generally, the lower bearing surface 333 of the second lateral wall 330 of the adapter 300 is located at least partially between the circular contours 396 defining the through opening 395. Optionally, the lower bearing surface 333 of the second lateral wall 330 of the adapter 300 is located at least partially longitudinally between the sides defining the cylindrical sleeve 390.
As a result, the lower bearing surface 333 of the second lateral wall 330 extends longitudinally towards the first longitudinal end 331 and/or the second longitudinal end 332 of the second lateral wall 330 of the adapter 300 beyond the circular profile 396 defining the through opening 395 and/or beyond the sides defining the cylindrical sleeve 390. Preferably, the lower bearing surface 333 of the second lateral wall 330 extends longitudinally symmetrically about the rotation axis 310. More preferably, and as can be seen in fig. 1, the lower bearing surface 333 of the second lateral wall 330 extends longitudinally along the entire second lateral wall 330, i.e. up to the first longitudinal end 331 and/or the second longitudinal end 332 of the second lateral wall 330.
As described above, and according to the first aspect of the invention, the adapter 300 includes the coupling member 360 to allow the adapter 300 to be mechanically coupled in the yoke 650 of the arm 600, thereby fixing the adapter 300 longitudinally in the yoke 650.
In the exemplary embodiment illustrated in fig. 1A and 1F, the coupling member 360 is located on the upper wall 340 of the adapter 300. In particular, the coupling member 360 includes:
a bearing surface 362 connected to the upper wall 340 of the adapter 300 by 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 button 361 located at the free longitudinal end of the bearing 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 a non-zero angle with the upper wall 340 of the adapter 300 in its natural configuration (i.e., without any force other than its own weight), preferably less than 10 °, such that the free end of the bearing surface 362 is located vertically above the upper surface of the upper wall 340.
The button 361 has a polygonal shape, and is particularly square in the example illustrated in fig. 1C, 1D, and 1F. Laterally, the button 361 is wider than the bearing surface 362 with respect to the lateral axis Y. In the vertical direction, the button extends projectedly above the bearing surface 362 with respect to the vertical axis Z.
The flexible hinge 365 is formed by two longitudinal notches 366 laterally bordering the bearing surface 362 on each side with respect to the transverse axis Y. Since the thickness of the bearing surface 362 relative to the vertical axis Z is relatively small (equal to or substantially equal to the thickness of the upper wall 340), the force vertically exerted on the push button 361 causes the bearing surface 362 to elastically deform, thereby producing a rotational movement of the coupling member 360 about the second longitudinal end 342 of the upper wall 340 of the adapter 300. As will be described below with reference to fig. 3A-3D, the button 361 is intended to interact with an opening 653 formed in the yoke 650 of the arm 600.
According to a particular feature of the first aspect of the invention, the lateral walls 320, 330 of the adapter 300 and the first longitudinal ends 321, 331, 341 of the upper wall 340 together form a fixation device 100 which makes it possible to retain the adapter 300 in the yoke 650 of the arm 600 with which it is intended to interact when the coupling member 360 is uncoupled from the yoke 650. As will be described below with reference to fig. 3A-3D, the fixation device 100 formed by the first longitudinal ends 321, 331 of the lateral walls 320, 330 and by the first longitudinal end 341 of the upper wall 340 together form a flat surface that facilitates its support against the longitudinal ends of the yoke 650. More specifically, the upper wall 340 does not extend longitudinally in front of the lateral walls 320, 330 of the adapter 300. Instead, the upper wall 340 extends longitudinally up to at most flush with the lateral walls 320, 330, but not beyond them.
Referring to fig. 2A and 2B, the adapter 300 illustrated in fig. 1 is assembled to a windshield wiper blade 500 comprising:
a structure 400 supporting a wiper strip 430;
a connector 200 rigidly connected to the structure 400;
according to the adapter 300 of the first aspect of the present invention or any one of the modifications thereof as described above, the adapter 300 is pivotally mounted on the connector 200.
Fig. 2B shows a cross-sectional view along the lateral plane YZ shown in fig. 2A.
The structure 400 of the windshield wiper blade 500 includes a support 440 that directly supports the wiper strip 430 as can be seen in fig. 2B. The support 440 is rigidly connected to the structure, in particular by means of the end piece 420. In the vertical direction, with respect to the vertical axis Z, the top of the wiper strip 430 and the support 440 is the deflector 410.
The connector 200 is rigidly connected to the structure 400 of the windscreen wiper blade 500 and serves as a mechanical interface with an adapter 300, which in turn serves as an interface with an articulated arm 600 of the windscreen wiper system 700 to which the windscreen wiper blade 500 is intended to be mounted. To this end, the adapter 300 is mechanically coupled to the connector 200. More specifically, the adapter 300 is pivotally mounted on the connector 200.
To this end, the connector 200 includes an axis of rotation 240 intended to interact with the axis of rotation 310 of the adapter 300. As can be seen in fig. 2B, the rotational axis 240 of the connector 200 is formed by:
a cylindrical recess 210 that interacts with a cylindrical sleeve 390 of the adapter 300; and
cylindrical sleeve 220, which interacts with cylindrical recess 380 of adapter 300.
When the adapter 300 is pivotally mounted on the connector 200, the cylindrical sleeve 390 of the adapter 300 is thus inserted into the cylindrical recess 210 of the connector, and the cylindrical recess 380 of the adapter 300 receives the cylindrical sleeve 220 of the connector 200. This advantageous configuration may enable the rotational axis 310 of the adapter 300 and the rotational axis 240 of the connector 200 to be coaxial. As a result, the adapter 300 is pivotally mounted on the connector 200 relative to the rotational axis 310 of the adapter and the rotational axis 240 of the connector.
Referring to fig. 3A-3D, two exemplary embodiments of a wiper system 700 according to a third aspect of the present invention are shown. In fig. 3B and 3C, the yoke 650 of the arm 600 is shown in cross-section to aid in the understanding of the invention.
Such a wiper system 700 comprises at least one arm 600 detachably fastened to an adapter 300 of a windscreen wiper blade 500 according to the second aspect of the invention and as described with reference to fig. 2. Each arm 600 includes a yoke 650 within which the adapter 300 is received and mechanically coupled by a complementarily shaped engagement. In addition, each arm 600 is rotated by an electric motor (not shown in fig. 3).
The yoke 650 of the arm 600 includes two lateral edges 651 that are connected to one another by an upper edge 652. As can be seen in fig. 3B, 3C and 3D, the yoke 650 is open at the lower vertical end, i.e. at the distal end of the lateral edge 651 relative to the upper edge 652 of the yoke 650.
The yoke 650 is also open at one of its longitudinal ends to allow insertion into the yoke 650 by translating the adapter 300. This open longitudinal end of the yoke 650 is arranged to one side of the 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 be supported in case of failure or malfunction of the coupling member 360.
At these distal ends, each lateral edge 651 includes a folded edge 655 that extends laterally toward the interior of the yoke 650. Each folded edge 655 of the yoke 650 thus forms a flange extending laterally towards the interior of the yoke 650 with respect to the associated lateral edge 651 with respect to the transverse axis Y.
When the adapter 300 is mounted in the yoke 650, at least one of the lateral walls 320, 330 of the adapter 300, preferably the lower bearing surfaces 323, 333 of both lateral walls 320, 330, bear against a folded edge 655 of the yoke that is positioned facing the lower bearing surface.
According to the invention, the folded edges of the yokes 655 are thus supported flush with the rotation axis 310 of the adapter 300 against the lower support faces 323, 333 of the corresponding lateral walls 320, 330 of said adapter 300. In other words, in alignment with the rotation axis 310, the adapter 300 is supported against the folded edge of the yoke 650 vertically with respect to the vertical axis Z.
In addition, as can be seen in fig. 3D, the outer faces 324, 334 of the lateral walls 320, 330 of the adapter 300 laterally bear against the lateral edges 651 of the yoke 650. Thus, this configuration makes it possible to hold the adapter 300 in the yoke 650 and thus ensure a satisfactory mechanical coupling between the windscreen wiper blade 500 and the arm 600 of the wiper system 700.
In addition, when the adapter 300 is received in the yoke 650 in its functional configuration (i.e., a configuration in which the wiper system 700 may be activated on a glazing panel of a motor vehicle), the coupling member 360 of the adapter 300 interacts with an opening 653 formed in the yoke 650. This configuration makes it possible to fix the windshield wiper blade 500 to the arm 600, and more specifically to prevent relative longitudinal movement between the adapter 300 and the yoke 650. In the example illustrated in fig. 3A-3C, opening 653 is located in an upper edge 652 of yoke 650. In addition, the shape of opening 653 of yoke 650 is complementary to the shape of button 361 of coupling member 360 of adapter 300, so as to allow button 361 to engage in opening 653 when adapter 300 reaches its functional configuration.
The yoke 650 of the arm 600 is closed at its longitudinal ends by a closing edge 654 extending laterally between two lateral edges 651 of the yoke 650. The closing edge 654 is, for example, integrally formed with the upper edge 652 and the lateral edge 651. In the vertical direction, the closing edge 654 is open at the lower vertical end in a similar manner to the lateral edge 651 of the yoke 650. However, the closure edge 654 does not have a folded edge similar to the folded edge of the lateral edge 651.
When the adapter 300 is received in the yoke 650 in its functional configuration, the closed edge 654 at least partially defines a cavity 656 at the first longitudinal ends 321, 331 of the adapter 300. In the event of failure of the means 360 for coupling the adapter 300 to the corresponding opening 653 of the yoke 650, the adapter 300 will be pushed towards the closing edge 654 of the yoke 650, and then the securing device 100 formed by the first longitudinal ends 321, 331 of the walls 320, 330, 340 of the adapter 300 will bear against the closing edge 654, thus preventing the windscreen wiper blade 500 from being pushed out of the yoke 650. The advantageously flat shape of the first longitudinal ends 321, 331 of the lateral walls 320, 330 of the adapter 300 makes it possible to house the adapter in a yoke 650 (which is closed longitudinally at the front by its closing edge 654), while allowing the fixing device 100 to rest against the closing edge 654 in case of failure.
Fig. 3B and 3C illustrate two variant embodiments of a connector 200 of a windscreen wiper blade 500 according to a second aspect of the invention:
in fig. 3B, the yoke 650 of the arm 600 further includes a protrusion 657 extending longitudinally toward the connector 200. The projection 657 is located distally of the closure edge 654 relative to the upper edge 652 of the yoke 650. In addition, the front face of the connector 200 is formed by two lateral surfaces 230 spaced laterally apart, each extending against one of the lateral walls 320, 330 of the adapter 300 within the recess 350 of said adapter 300. The lateral surfaces 230 of the connector 200 are laterally spaced apart from one another to allow the raised distal end 658 to be partially inserted between the lateral surfaces 230 of the connector 200;
In fig. 3C, the front face of the connector 200 is formed by a surface 250 that extends laterally between the lateral walls 320, 330 of the adapter 300 within the recess 350 of the adapter 300. Thus, the surface 250 forms a single flat surface at its longitudinal end facing the cavity 656 formed by the closed edge 654 of the yoke 650 of the arm 600.
The present invention relates generally to an adapter 300 for securing a windshield wiper blade 500 to an arm 600 of a wiper system 700, and in particular, the adapter 300 is pivotally mounted to a connector 200 of the windshield wiper blade 500. The adapter 300 comprises two lateral walls 320, 330 connected to each other by an upper wall 340 and forming a recess 350 therebetween for the connector 200. At the distal end of the lateral walls 320, 330 with respect to the upper wall 340, the connector comprises a lower bearing surface 323, 333 intended to interact with the folded edge 655 of the yoke 650. According to the invention, on each lateral wall 320, 330, the lower bearing surface 323, 333 of the adapter 300 extends at least partially in a region aligned with the rotation axis 310 of the adapter 300 with respect to the connector 200.
Of course, the invention is not limited to the examples just described and many modifications may be made to these examples without departing from the scope of the invention. In particular, the various features, forms, variations, and embodiments of the invention may be associated with each other in various combinations as long as they are compatible or not mutually exclusive. In particular, all the variants and embodiments described above can be combined with one another.
