Description

Adapter for a wiping system

The field of the invention is that of wiper systems designed for motor vehicles. More particularly, the field of the invention is that of connection means implemented between the wiper arm and the wiper of such a wiper system.

Currently, motor vehicles are equipped with wiping systems designed to clean the glass surfaces of the motor vehicle, in particular the windshield of the motor vehicle. Such a wiper system comprises at least one wiper arm and a wiper driven by the wiper arm. The wiper arm is connected to the motor of the vehicle and the wiper comprises at least one wiper blade designed to be in contact with the glass surface to be wiped. In order to be able to drive the wiper, an adapter is arranged between the wiper and the wiper arm. More particularly, the adapter is arranged between the wiper arm and a connector connected to the wiper.

The adapter and connector are then assembled such that they are rotationally movable relative to each other. This therefore allows the wiper to be rotatably moved so that the wiper contacts the glass surface of the vehicle as much as possible. The rotational assembly is achieved in particular thanks to the means for rotating the adapter comprising a cylindrical column which can cooperate with complementary means of the connector and at least one support.

A problem with current devices for rotation is, inter alia, that their cooperation with the connector remains suboptimal. Indeed, while the means for rotating the adapter provides acceptable rotation thereof relative to the connector, its retention is sometimes flawed, particularly when forces occur that cause misalignment of the adapter relative to the connector. Therefore, the mechanical retention force between the adapter and the connector is too small.

It is therefore an object of the present invention to improve the current devices for rotating an adapter without making its design or production more complex and without increasing its production costs.

The invention thus relates to an adapter for fixing a wiper to an arm of a wiping system, the adapter being configured to be fitted so as to pivot about an axis of rotation on a connector of the wiper, the adapter comprising at least two parallel walls which are opposite to each other in a transverse direction of the adapter and so that they at least partially define a receiving space for the connector, the adapter comprising at least one means for rotating the adapter relative to the connector formed on a lateral wall, the means for rotating comprising at least one support opening in the receiving space, the adapter being characterized in that the support comprises at least three points configured to be supported on the connector, the three points being separated from each other by angular sectors without material.

It will be appreciated that the support is provided in one of the lateral walls of the adapter. It will be appreciated that the support comprises a receiving area provided in the lateral wall.

It will be appreciated that the receiving area is configured to receive an element for rotating the connector. For example, the receiving area is free of material.

For example, by virtue of the complementation of shape, the support is configured to allow the adapter to pivot relative to the connector when the adapter is fitted to the connector.

It will be appreciated that the support is formed by three points integral with the lateral wall. For example, these three points are formed with the lateral walls of the adapter.

It will be appreciated that these three points define the receiving area of the support.

These three points may define a circular or cylindrical receiving area.

In some embodiments, the three points define a receiving area configured to receive an element for rotating the connector, the receiving area being circular.

For example, the at least three points are substantially evenly or regularly distributed over the circumference of the receiving area. For example, the at least three points are equidistant from each other.

For example, in the longitudinal direction of the adapter, the at least three points are positioned staggered.

The wiper and the arm form part of a wiping system of a vehicle, the wiping system being designed to clean at least a part of a glass surface of said vehicle. The adapter is thus fitted to pivot relative to the connector such that the wiper, in particular the wiper blade supported by the wiper, follows the curve of the glass surface.

This rotation of the adapter relative to the connector occurs in particular thanks to a device for rotating the adapter, comprising at least a support and a cylindrical post located on the lateral wall opposite to the lateral wall supporting the support. In particular, the support comprises at least three points which can be supported on the connector, and more particularly on a cylindrical projection designed to cooperate with the support of the device for rotation. Each of these three points is then separated by at least one angular sector without material. "no material" means the fact that: the angular sectors form the areas of the support that do not support the cylindrical projections of the connector.

The advantage derives from the device for rotating the adapter, in particular the support of the device comprising at least three points configured to be supported on the connector, since the support capacity of the cylindrical protrusion is increased in said support, the mechanical strength of the adapter is increased with respect to the connector, while maintaining the pivoting of one with respect to the other.

According to a feature of the invention, the means for rotating the adapter relative to the connector comprise at least one cylindrical post formed on the lateral wall opposite to the lateral wall of the support, wherein the cylindrical post protrudes towards the receiving space while being aligned with the support along the rotation axis.

The connector then comprises a cylindrical socket which can cooperate with a cylindrical post of the means for rotating the adapter, and is therefore designed to be aligned along this axis of rotation.

According to a feature of the invention, the support comprises at least five points configured to be supported on the connector, wherein three of the five points are positioned in a first semicircle of the support and the other two points are positioned in a second semicircle of the support.

The first semicircle and the second semicircle are complementary to each other and do not overlap such that they form a circle inscribed in the support. This thus allows an optimal distribution of points in order to maintain at least the cylindrical projection of the connector in the support of the device for rotation.

According to a feature of the invention, the means for rotating comprise at least five grooves formed in the thickness of one of the lateral walls of the adapter, on the periphery of the support, wherein the five grooves open at angular sectors devoid of material and define three teeth distinct from each other of the means for rotating.

It will be appreciated that the recess is provided in the lateral wall of the adapter provided with the support.

It will be appreciated that the ends of the at least 3 teeth define a region for receiving the support.

"groove" refers to a gap in the material of the adapter that is placed around the support such that the groove abuts the aforementioned tooth. For example, the grooves extend in parallel directions. For example, the grooves extend radially with respect to the axis of rotation. According to an example of the invention, two of these grooves are formed on the periphery of the support at a first semicircle, while the other three grooves are formed on the periphery of the support at a second semicircle. It will thus be appreciated that the first tooth extends on the periphery of the support at a first semicircle of the support, while the second and third teeth extend on the periphery of the support at a second semicircle of the support.

According to an example of the invention, each of these grooves of the means for rotating is open on the support at one of the angular sectors of the means for rotating.

According to a feature of the invention, each of the teeth comprises at least one free end face facing the support of the means for rotating, wherein each of the free end faces forms one of the points of the means for rotating the adapter designed to be supported on the connector.

It will thus be appreciated that the free end face of the first tooth forms one of the points of the means for rotation which lie in the first semicircle of the support, while the free end faces of the second tooth and the third tooth each form one of the points of the means for rotation which lie in the second semicircle of the support.

According to a feature of the invention, at least one of the grooves of the means for rotating extends along a straight line and at least one of the teeth extends along the same straight line.

According to an example of the invention, each of these teeth extends in a straight line with one of the grooves of the means for rotating.

According to a feature of the invention, the teeth of the means for rotating extend in a main extension direction parallel to the direction in which the connector is inserted into the receiving space of the adapter.

According to a feature of the invention, at least one of these grooves of the means for rotating opens on the outer edge of the lateral wall of the adapter.

According to an example of the invention, all grooves of the means for rotating are open on the outer edge of the lateral wall of the adapter. More specifically, two of the grooves extending in a first semicircle of the support open on a first outer edge of the lateral wall, and three of the grooves extending in a second semicircle of the support open on a second outer edge of the lateral wall opposite the first outer edge in the vertical direction of the adapter.

According to a feature of the invention, at least one of the teeth includes a chamfer designed to facilitate insertion of the adapter onto the connector.

As will be appreciated from the foregoing, a chamfer is formed on at least one of the teeth opposite the free end face of the tooth. It will thus be appreciated that the chamfer is formed at the second outer edge of the lateral wall constituting the adapter.

The invention also relates to an assembly of a connector designed to be integral with a wiper and an adapter as described in this document, the connector and adapter being fitted so as to pivot relative to each other by means of the aforementioned support for the rotating device.

The invention also relates to a wiper comprising at least one wiper blade, a connector and an adapter according to the aforementioned features, the blade being supported by the connector, the connector being fitted so as to pivot with respect to the adapter.

According to an example of the invention, the blade of the wiper is indirectly supported by the connector, in particular by an elongated support made of synthetic material, or by one or more skeletons housed in the wiper blade.

The invention also relates to a wiping system for a motor vehicle, comprising a wiper according to the aforementioned characteristics and an arm connected to the wiper by means of an adapter according to the aforementioned characteristics.

Other features, details and advantages of the invention will become more apparent from a reading of the following description provided with an indication in connection with the accompanying drawings, in which:

FIG. 6 is an exploded view of the adapter and connector of FIG. 1.

It should be noted at the outset that although the drawings illustrate embodiments of the invention in detail, it is to be understood that these drawings may be used to better define the invention where appropriate. It is also noted that these drawings illustrate only examples of the manner in which the invention may be practiced. Finally, like reference numerals refer to like elements throughout the several views.

Fig. 1 shows a wiping system 1 according to the invention. As illustrated, the wiping system 1 comprises at least one wiper 2 and at least one arm 4, which are connected to each other by means of at least one adapter 6 according to the invention. More precisely, the adapter 6 makes it possible to connect a connector 8 supporting the wiper 2 to the wiper arm 4, which wiper comprises a wiper blade 10.

The blade 10 of the wiper 2 is designed to be in contact with a glass surface (not shown) of a vehicle, which is equipped with the wiping system 1 according to the invention. According to an example of the invention, the wiper 2 may comprise at least one stiffening unit (for example an elongated support made of synthetic material) or one or more metal skeletons, and at least one air deflector 12. "air deflector 12" means the fact that: the deflector is configured to convert the pressure exerted by the air flow circulating along the glass surface into a force for supporting the wiper 2 against the glass surface of the vehicle.

The wiper arm 4 itself is configured to rotate the wiper 2. Thus, the arm 4 comprises at least a first end 14 integral with the adapter 6, and a second end 16 opposite the first end 14 in the main extension direction P of the arm 4, the second end 16 being integral with a drive motor (not shown) housed in the motor vehicle.

The adapter 6 and the connector 8, in particular their cooperation, will now be described in more detail with the aid of fig. 2 to 6.

The adapter 6 extends in a longitudinal main extension direction L and comprises at least two lateral walls 18 opposite each other in a transverse direction T of the adapter 6. Each lateral wall 18 extends on a plane L, V of a trihedron L, V, T shown in each figure.

The two lateral walls 18 participate in defining a space 20 for receiving the connector 8. At least one bridge 22 extends in the plane L, T of the adapter 6 in the interior of the volume delimited by the lateral wall 18 and the upper wall 24. The bridge 22 connects the lateral walls 18 of the adapter 6. Rather, the bridge 22 cooperates with the lateral wall 18 to define a space 20 for receiving the connector 8.

The adapter 6 further comprises at least one upper wall 24 extending mainly in the plane L, T of the adapter 6 and over the entire longitudinal dimension L of said adapter 6. However, the upper wall 24 comprises a through-hole 26, which can be seen in particular in fig. 3, which is formed at least in correspondence with the space 20 for receiving the connector 8 and faces a region 28 for receiving the wiper arm. It will thus be appreciated that the space 20 for receiving the connector 8 is open on both sides of the adapter 6 in the vertical direction V, these openings being inscribed in a plane parallel to the plane L, T.

The region 28 for receiving the wiper arm corresponds to a space designed to receive the first end of the arm and which is delimited by a hole 30 (shown in fig. 4) for inserting said arm, which hole is formed at the longitudinal end of the adapter 6 such that the insertion hole 30 opens into the receiving region 28. The receiving area 28 comprises at least one blocking post 32 (shown in fig. 3) protruding from said receiving area 28 in the vertical direction V of the adapter 6, said blocking post 32 being capable of cooperating with a hole (not shown) provided in the first end of the arm. Thus, the blocking post 32 makes it possible to block the longitudinal movement of the arm when it is received in the receiving area 28. It will thus be appreciated that the upper wall 24 blocks vertical movement of the arms and that the lateral walls 18 block lateral movement of the arms.

The adapter 6 further comprises at least two buttons 34 (shown in fig. 3) extending from the receiving area 28 and forming a gripping area for unlocking the adapter 6 relative to the arm. Each of the buttons 34 is then connected to a single bracket 36 that extends along the receiving area 28 on the plane L, T of the adapter 6 and opposite the upper wall 24. The bracket 36 is elastically deformable, particularly according to vertical movement, when the user grasps the button 34. "elastically deformable" means the fact that: the support 36 can be deformed, in particular in the vertical direction V of the adapter 6, and can then return to its original state without breakage or irreparable deformation of the material taking place. This thus makes it possible to separate the wiper arm and the blocking post 32 cooperating with the aperture of the arm, in particular by vertical displacement.

At least one chamfer area 38 (shown in fig. 3) is formed between the upper wall 24 of the adapter 6 and one of the lateral walls 18. More precisely, the chamfer area 38 is formed at the junction between the upper wall 24 and one of the lateral walls 18, and such that the chamfer area forms an inclined plane with respect to the main plane of the upper wall 24 and the main plane of the lateral walls 18. This type of chamfer area 38 reduces the risk of injury in case of collision between a pedestrian and a vehicle equipped with the adapter 6 according to the invention. According to the illustrated example of the invention, a chamfer area 38 similar to the chamfer area just described is formed on the other lateral end of the adapter 6, and the two chamfer areas 38 are made to face each other in the lateral direction T of the adapter 6.

The adapter 6 is configured to be fitted such that it pivots on the connector 8 (as shown in fig. 1, 2 and 6) about an axis of rotation R that is parallel to the transverse direction T of the adapter 6. For this purpose, the adapter 6 comprises at least one means 40 for rotating the adapter 6 relative to the connector 8, which means are formed on the lateral wall 18 of the adapter 6 and which means open or protrude on the receiving space 20 of the connector 8. Thus, a first lateral wall 18a supporting the support 42 of the device 40 for rotation, and a second lateral wall 18b supporting a cylindrical post 44 (shown in particular in fig. 4) protruding towards the receiving space 20 are defined. Thus, the support 42 and the cylindrical post 44 are aligned along the rotational axis R. The means 40 for rotating may be formed by the support 42 only, but the means may also be formed by a combination of the support 42 and the cylindrical post 40.

According to a feature of the invention, the support 42 (shown in particular in fig. 5) of the device 40 for rotation comprises at least three points 46 configured to bear on the connector, these three points 46 being separated from each other by angular sectors 48 of no material. Thus "angular sector 48" means the fact that: these sectors form empty spaces free of material and thus cannot be supported against the connector. As shown in the example of fig. 5, the support 42 includes five different angular sectors 48.

According to the example illustrated in fig. 5, the support 42 comprises five different points 46. These five points 46 of the support 42 are configured to bear on the connector 8, said five points 46 being separated by the five angular sectors 48 described above.

Since the support 42 of the means 40 for rotating is in the form of a circle having a centre C, a first semicircle 50a and a second semicircle 50b are defined, seen in plane L, V. These semicircles 50a and 50b are shown in dashed lines in fig. 5. It will thus be appreciated that the first semicircle 50a and the second semicircle 50b are different from each other, i.e. they do not overlap, and are complementary to each other such that they form a circle with a centre C, within which the support 42 is inscribed. Thus, a first point 46a, a second point 46b, and a third point 46c of the five points 46 configured to be supported on the connector are positioned on the first semicircle 50a, and a fourth point 46d and a fifth point 46e of the five points 46 are positioned on the second semicircle 50b.

The means 40 for rotating also comprise at least five distinct grooves 52 formed in the thickness of the first lateral wall 18a and extending radially towards the outside of the support 42. Corner sectors 48 without material abut grooves 52 associated therewith. This is why the means 40 for rotating comprise five grooves 52 and five grooves. More precisely, a first groove 52a and a second groove 52b are defined, each extending from one of the angular sectors 48 of the support 42, devoid of material, and located in the first semicircle 50a, and a third groove 52c, a fourth groove 52d and a fifth groove 52e are defined, each extending from one of the angular sectors 48 of the support 42, devoid of material, and located in the second semicircle 50b of said support 42.

According to an embodiment of the invention, at least one of the grooves 52 of the means 40 for rotating opens onto the outer edge 54 of the first lateral wall 18 of the adapter 6. Thus defining a first outer edge 54a of the first lateral wall 18a facing towards the upper wall 24 of the adapter 6, and defining a second outer edge 54b of the first lateral wall 18a opposite to the first outer edge 54a in the vertical direction V of the adapter 6. Thus, according to an embodiment of the present invention, the first groove 52a and the second groove 52b of the means for rotating 40 extend from the support 42 and open on the first outer edge 54a of the first lateral wall 18a, while the third groove 52c, the fourth groove 52d and the fifth groove 52e extend from the support 42 and open on the second outer edge 54b of the first lateral wall 18 a. Furthermore, each of the grooves 52 of the means 40 for rotating extends mainly in the vertical direction V of the adapter 6. This type of arrangement facilitates the release of the adapter 6 during its production.

As can be seen in fig. 5, the five grooves 52 define three teeth 56 that are different from one another. More specifically, the first and second grooves 52a, 52b define first teeth 56a extending from the support 42 up to the first outer edge 54a of the first side wall 18a, and the third, fourth, and fifth grooves 52c, 52d, 52e define second and third teeth 56b, 56c that are different from each other extending from the support 42 up to the second outer edge 54b of the first side wall 18 a.

Each of the teeth 56 of the means for rotating 40 comprises a free end surface 58 facing the support 42 of the means for rotating 40, wherein each of the free end surfaces 58 forms one of the points 46 of the means for rotating 40 designed to be supported on the connector 8, as previously described. Furthermore, each of the teeth 56 of the means 40 for rotating extends from the support 42 in the vertical direction V of the adapter 6.

Thus, the aforementioned second point 46b comprised in the first semicircle 50a is formed at the free end face 58 of the first tooth 56a, whereas the first point 46a and the third point 46c likewise comprised in the first semicircle 50a are each formed by the peripheral edge 60 of the support 42, wherein the peripheral edge 60 of the support 42 in particular has a curved form participating in defining the circle inscribed by the support 42. A fourth point 46d and a fifth point 46e inscribed in the second semicircle 50b are formed at the free end surfaces 58 of the second tooth 56b and the third tooth 56c, respectively.

According to a feature of the present invention, at least one of the grooves 52 of the means for rotating 40 extends along a straight line and at least one of the teeth 56 extends along the same straight line. More precisely, according to the illustrated example of the invention, the first groove 52a extends along a first vertical line D1 with the second tooth 56b, the second groove 52b extends along a second vertical line D2 with the third tooth 56c, and the fourth groove 52D extends along a third vertical line D3 with the first tooth 56 a.

Generally, the teeth 56 are alternately positioned in the longitudinal direction L. The same applies to the grooves 52, which are also positioned alternately displaced in the longitudinal direction L.

According to the invention, at least one of the teeth 56 of the support 42 comprises a chamfer 62 designed to facilitate the insertion of the adapter 6 onto the connector 8. More precisely, according to the example illustrated, the second tooth 56b and the third tooth 56c each comprise a chamfer 62 formed opposite to their free end face 58, so that the chamfers facilitate the insertion of the adapter 6 onto the connector 8.

As can be seen in fig. 4, the cylindrical post 44 includes a chamfered leading edge 45 facing opposite the upper wall 24. It will thus be appreciated that the leading edge 45 is formed on the cylindrical post 44 such that the leading edge facilitates insertion of the adapter 6 onto the connector.

The connector 8 (shown in particular in fig. 6) comprises at least a first portion 68 for fixing to the wiper, wherein the first fixing portion 68 in particular forms means for attaching the wiper blade of the wiper between a first lug 70a and a second lug 70b of the first portion 68. The connector 8 further comprises a second portion 72 for fixing to the adapter 6, which extends vertically from the first portion 68 opposite to the first and second lugs 70a, 70b of the first portion 68.

The second portion 72 of the connector 8 includes a circular socket 66 that forms a cylindrical recess in the material of the second portion 72. More precisely, a circular socket 66 is formed in the second portion 72 of the connector 8, so that it can cooperate with the cylindrical post of the adapter 6 along the rotation axis R. The second portion 72 of the connector 8 further comprises a cylindrical strand 74 forming a protrusion of said second portion 72 and being opposite to the volume of the second portion, so that the cylindrical strand 74 can cooperate with the support 42 of the means 40 for rotating the adapter 6 along the rotation axis R. It will thus be appreciated that the cylindrical strand 74 is designed to bear on at least three points of support 42 of the device 40 for rotating the adapter 6 described above, or five points of support 42.

The procedure for assembling the adapter 6 on the connector 8 will now be described with the aid of fig. 4 to 6.

The assembly process comprises at least a first step during which the connector 8 is positioned facing the receiving space 20 of the adapter 6 and such that the second outer edge 54b of the first lateral wall 18a faces said connector 8. In a second step, the adapter 6 is positioned on the connector 8 such that at least a portion of the connector 8 is received in the receiving space 20 of the adapter 6. More precisely, the adapter 6 translates on the connector 8 in the vertical direction V of said adapter 6, so that the second portion 72 of the connector 8 is in contact with the chamfer 62 provided on the second tooth 56b and the third tooth 56c of the means for rotating 40.

The insertion of the second portion 72 of the connector 8 then continues, according to the vertical translational movement, so that the second portion 72 of said connector 8 is in contact with the leading edge 45 of the cylindrical post 44. Finally, the cylindrical strand 74 is housed in the support 42 of the device 40 for rotation according to the invention, and the circular socket 66 receives the cylindrical post 44 of the device 40 for rotation of the adapter 6.

It will thus be appreciated that upon completion of the assembly process, the means 40 for rotating the adapter 6, including at least the support 42 and the cylindrical post 44, and the cylindrical strand 74 and the circular socket 66 of the connector 8 are aligned along the axis of rotation R of the adapter 6 relative to said connector 8.

Thus, as just described, an advantage derived from the adapter is that the means for rotating of the adapter, in particular the support of the means comprising at least three points configured to be supported on the connector, increases the mechanical retention of the adapter on the connector. An advantage deriving from this type of invention is also that a support comprising at least three support points can be obtained in a simple manner, without this complicating the existing production.

However, as just described, the invention is not limited to the devices and configurations specifically described and illustrated, but is also applicable to all equivalent devices or configurations, as well as any combination of such devices or configurations.
