Description

Technical Field

[0001] The field of the invention is that of wiper systems for motor vehicles. More specifically, the field of the invention is that of adapters between a wiper arm and a wiper of such a wiper system. Background Art

[0002] Motor vehicles are usually equipped with wiper systems for cleaning the glass surfaces of motor vehicles, in particular their windscreens. Such wiper systems comprise 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 come into 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 specifically, the adapter is arranged between the wiper arm and a connector connected to the wiper. The adapter is thus integral with the wiper arm, more specifically with the free end of the wiper arm, this type of engagement being removable so that the wiper can be replaced after wear.

[0003] In order to optimally clean the glass surface of a vehicle by a wiper system, said wiper system, and in particular its wipers, must be placed against the glass surface to be cleaned. Devices are therefore known that participate in placing the wipers in position, such as deflectors, which are located on the wipers and which ensure that the wipers are placed in position under the effect of the air flow when the vehicle is moving. However, although placing the wiper blades in position is efficient, it is not optimal and can therefore be improved.

[0004] Furthermore, mounting and / or removing the wiper from the arm is not optimal. In fact, activating the locking device without minimum precautions can lead to its breakage or irreversible damage, thus limiting its use. Summary of the invention

[0005] The object of the present invention is therefore to improve the placement of the wiper on the glass surface in a simple manner while allowing the wiper to be installed and / or removed without causing damage to the wiper element. The placement of the wiper is achieved in particular by creating a low-pressure area at the rear of the adapter, which is along the air flow, against the flow direction of the wiper system, thus improving the overall performance level of the wiper system.

[0006] The main purpose of the present invention is an adapter for fixing a wiper on the arm of a wiper system, the adapter extending in the longitudinal direction, the adapter being configured to be mounted on the connector of the wiper to rotate around a rotation axis transverse to the longitudinal direction, the adapter comprising at least one side wall and an upper wall, the side wall and the upper wall participating in defining the internal space of the adapter, the adapter comprising an inner wall extending at least partially into the internal space of the adapter, characterized in that the adapter comprises a locking device designed to make the adapter longitudinally integral with the arm of the wiper system, the locking device being mounted to pivot on the upper wall around a pivot axis, the locking device comprising a limiting device for limiting its pivoting, the limiting device being supported against the inner wall.

[0007] The wiper and the arm form part of a vehicle wiper system for at least partially cleaning the glass surface of said vehicle. Thus, the wiper system comprises an arm rotated by the motor of the vehicle and ensuring the rotational movement of the wiper, the wiper being integral with the arm via an adapter and a connector, resting against the glass surface so that a blade supported by the wiper removes raindrops and / or solid debris deposited thereon from the glass surface.

[0008] The locking device also participates in fixing the adapter on the arm by locking the position of the adapter on the arm.Through its pivoting, the locking device facilitates the installation and / or removal of the adapter on the arm while limiting damage to the components of the adapter and / or the arm.

[0009] The limiting means for limiting the locking means prevents the locking means from pivoting in at least one of its pivoting directions. It should be understood that in this case, the limiting means can prevent the locking means from pivoting too far, for example by a stop, thereby limiting the risk of breaking the component elements of the adapter and / or the arm.

[0010] According to the invention, the pivoting of the locking device is limited by a stopper of the limiting device 24 which abuts against the inner wall of the adapter.

[0011] According to an optional feature of the invention, the pivot axis is parallel to the longitudinal direction.

[0012] According to an optional feature of the present invention, the side wall and the upper wall respectively have a free edge and a common edge of the side wall and the upper wall, and the adapter has a triangular cross-section when viewed on a plane perpendicular to the longitudinal direction, which is defined by the free edge of the side wall, the free edge of the upper wall, and the common edge of the side wall and the upper wall, and the upper wall is curved between the common edge and its free edge when viewed on a plane perpendicular to the longitudinal direction.

[0013] Furthermore, the free edge of the upper wall corresponds to the edge positioned across the airflow that hits the upper wall when the wiper system is positioned on the vehicle. In other words, the free edge of the upper wall is the edge that is furthest from the front of the vehicle when the wiper system is mounted on said vehicle. It is therefore understood that, according to the trajectory of the airflow when the wiper system is mounted on the vehicle, the free edge of the side wall and the side wall itself are located at the rear of the wiper system, between the glass surface and the free edge of the upper wall.

[0014] According to another optional feature of the invention, the curve of the upper wall between the common edge and its free edge, seen in a plane perpendicular to the longitudinal direction, is incorporated in a circle.

[0015] According to another optional feature of the invention, the inner wall at least partially participates in defining a receiving area, which is designed to receive the connector. It should be understood that the receiving area is at least defined by the inner wall, but other walls can also contribute to defining the receiving area. It should be understood that in this case, once the connector is mounted on the adapter, the connector is at least partially located in the area for receiving the adapter.

[0016] According to an optional feature of the invention, the inner wall has a contact surface facing the limiting device and a guide surface participating in delimiting the receiving area, the limiting device bearing against the contact surface of the inner wall.

[0017] According to another optional feature of the invention, the locking device comprises at least one push unit integrated in the profile of the upper wall and a blocking unit extending at least partially into a receiving receptacle designed as a receiving arm.

[0018] It should be understood that the push unit extends in a form matching the shape of the upper wall, for example, the push unit is flush with the upper wall. The push unit is also the unit of the locking device on which the user applies force to allow the locking device to pivot.

[0019] Furthermore, the blocking unit is a unit of the locking device which is configured to come into contact with the arm in order to integrate the adapter with the arm and / or release the adapter from the arm.

[0020] According to another optional feature of the invention, the locking device comprises at least one hinge connecting the push unit to the upper wall, the push unit being surrounded by a groove separating the push unit from the upper wall. The hinge firstly allows the locking device to pivot about a pivot axis and secondly makes the locking device integral with the upper wall.

[0021] According to another optional feature of the present invention, the pushing unit has a parallelepiped shape, the pushing unit has at least one upper side and one lower side extending parallel to the longitudinal direction, the hinge is located between the lower side and the upper wall of the pushing unit, and the groove extends on the other three sides of the pushing unit.

[0022] In this case, it can be understood that the upper side is the side of the pushing unit closest to the common edge between the side wall and the upper wall, and the lower side is the side of the pushing unit closest to the free edge of the upper wall.

[0023] By means of this particularly clever arrangement, pivoting of the locking unit makes it possible to position the blocking unit in the receiving receptacle and / or to remove the blocking unit from the receiving receptacle, thereby integrating the adapter with the arm and / or releasing the adapter from the arm.

[0024] According to another optional feature of the invention, the push unit has a curved profile, seen in a cross section perpendicular to the longitudinal direction, the curved profile of the push unit being integrated into the profile of the upper wall.

[0025] According to another optional feature of the present invention, the push unit comprises an outer surface oriented toward the external environment of the adapter and an inner surface oriented toward the internal space of the adapter, and the push unit has a pattern on its outer surface that facilitates adhesion. Such a pattern is, for example, a texture on the outer surface of the upper wall.

[0026] According to another optional feature of the invention, the restriction device forms part of the blocking unit. In other words, the restriction device and the blocking unit form a one-piece assembly, i.e. the restriction device and the blocking unit cannot be separated from each other without causing damage to the restriction device and / or the blocking unit.

[0027] According to another optional feature of the invention, the blocking unit is longitudinally bounded by an end face of the restriction device.An "end face" refers to a face located at a longitudinal end of the restriction device.

[0028] According to another optional feature of the invention, the limiting means is formed by a stop surface which intersects the end surface and faces the inner wall. More specifically, the stop surface extends on a plane which intersects an extension plane of the end surface of the limiting means.

[0029] According to another optional feature of the invention, the locking device is pivotable about the pivot axis through a maximum angle of 20°.

[0030] Preferably, the pivot angle of the locking device is at most 15°.

[0031] Even more preferably, the pivoting angle of the locking device is at most 10°.

[0032] According to another optional feature of the invention, the blocking unit extends from the pushing unit to the receiving receptacle, the blocking unit comprising a bent portion and a free end, the free end being located in the receiving receptacle when the locking unit is in position to lock the adapter to the arm.

[0033] According to another optional feature of the invention, the limiting means causes the free end of the blocking unit to extend longitudinally.

[0034] According to another optional feature of the invention, the adapter comprises at least one reinforcement extending between the inner wall and the side walls and / or the upper wall. In particular, the reinforcement comprises, for example, a wall extending mainly in a plane substantially perpendicular to the longitudinal direction. Such a reinforcement makes it possible to strengthen the structure of the adapter and increase its rigidity.

[0035] According to another optional feature of the invention, the reinforcement comprises an opening that at least partially participates in defining the receiving receptacle. It should be understood that the opening is designed to receive at least part of the arm.

[0036] According to another optional feature of the invention, the receiving receptacle is laterally offset relative to the receiving area.

[0037] According to another optional feature of the present invention, the receiving receptacle is closer to the side wall than the receiving area. In other words, the receiving receptacle is located between the receiving area and the side wall.

[0038] According to another optional feature of the invention, the receiving receptacle extends in a main extension plane parallel to the longitudinal direction, the main extension plane being visible in a middle position of said receiving receptacle, the main extension plane of the receiving receptacle intersecting the receiving area.

[0039] According to another optional feature of the invention, the upper wall comprises at least one air disturbance device extending in the longitudinal direction and opening towards the outside of the adapter.

[0040] According to another optional feature of the invention, the air disturbance means is in the form of a channel.

[0041] According to another optional feature of the invention, the air disturbance means are in the form of ribs.

[0042] Furthermore, the subject of the invention is a connection device for a wiper, comprising at least one connector and an adapter according to any of the preceding features, the connector being mounted so as to rotate about an axis of rotation by means of a rotation device.

[0043] The invention also relates to a wiper blade comprising at least one connecting device according to the preceding features, or an adapter according to any of the preceding features.

[0044] Finally, the subject of the invention is a wiper system comprising at least one wiper arm comprising at least one rod housed in a receiving receptacle of an adapter and a wiper according to the preceding features. In this case, by "rod" is meant a solid elongated element, for example having a rectangular or disc-shaped cross section, seen in a plane perpendicular to the main direction of extension of the rod.

[0045] According to another optional feature of the invention, at least one end of the rod has a form complementary to that of a receptacle for receiving the adapter, the rod having a notch cooperating with the locking means so as to longitudinally lock the position of the adapter on the rod.

In particular, if the selection of features is sufficient to provide technical advantages and / or distinguish the present invention from the prior art, variations of the present invention may be envisaged that include only such feature selections as described below, without regard to the other features described.

[0054] In the drawings, elements common to several figures retain the same reference numerals. DETAILED DESCRIPTION

[0055] In the detailed description that follows, the terms "longitudinal", "transverse" and "vertical" refer to the orientation of the wiper system according to the invention. The longitudinal direction corresponds to the main extension direction of the adapter according to the invention, which is parallel to the longitudinal axis L in the L, V, T shown in the figures. The transverse direction corresponds to the main extension direction of the reinforcement, which is parallel to the transverse axis T in the reference system L, V, T, which is perpendicular to the longitudinal axis L. Finally, the vertical direction corresponds to the direction parallel to the vertical axis V of the reference system L, V, T, which is perpendicular to the longitudinal axis L and the transverse axis T.

[0056] Figure 1 A wiper system 6 is shown, which is configured to ensure cleaning of a glass surface of a vehicle, such as a windshield, thereby improving the driver's visibility of the road in front of the vehicle, for example in rainy weather, or also to remove solid debris adhering thereto from said glass surface. The wiper system 6 extends mainly in a longitudinal direction L and comprises at least one wiper arm 4, which supports a wiper 2 at one end and is connected to the vehicle at another opposite end in the longitudinal direction L.

[0057] Both the arm 4 and the wiper 2 extend mainly in the longitudinal direction L of the wiper system 6. More specifically, the arm 4 comprises a connecting body for integrating the arm 4 with the vehicle, and a rod 60 extending from the connecting body to one end of the arm 4. By "rod" is meant a solid element extending in the longitudinal direction L. In this case, the rod 60 has a rectangular cross section, seen in a plane perpendicular to the longitudinal direction L. However, a rod 60 having a disc-shaped, triangular or other cross section would not depart from the scope of the invention.

[0058] Furthermore, in particular, the wiper 2 is designed to be rotated by an arm 4 which bears against the glass surface of the vehicle, the arm 4 itself being rotated by a motor (not shown), for example an electric motor on board the vehicle.

[0059] In order to connect the wiper 2 to the end of the arm 4, the wiper 2 comprises a connection device 56, which comprises at least one connector 8 supporting a wiper blade 68 of the wiper 2, and an adapter 1, which is mounted to rotate on the connector 8, the adapter 1 being able to cooperate with the end of the arm 4. In particular, it should be understood that the wiper blade 68 of the wiper 2 is intended to come into contact with the glass surface of the vehicle. In addition, the connector 8 is configured to directly or indirectly support the wiper blade 68.

[0060] The adapter 1 and the connector 8 are connected by a rotating device 58 (such as Figure 3 The rotating device 58 is rotated (as shown) about a rotation axis R that is substantially parallel to the transverse direction T. A more detailed description of the rotating device 58 will be provided later in the description.

[0061] like Figure 2 and 3 As shown more particularly in , the adapter 1 extends mainly in a longitudinal direction L. The adapter 1 comprises at least one side wall 10 and an upper wall 12 , each having a free edge 14 , 16 and an edge 18 common to the side wall 10 and the upper wall 12 .

[0062] The side wall 10 extends mainly in a plane parallel to the longitudinal direction L and the vertical direction V. In this case, the side wall 10 has a free edge 14 and an edge 18 common to the upper wall 12, which joins the side wall 10 and the upper wall 12, each extending in different planes.

[0063] The upper wall 12 also has a free edge 16 and extends between its free edge 16 and a common edge 18. The upper wall 12 also has a curvature, in particular as Figure 5 As shown, Figure 5 is based on Figure 3 The cross section shown is produced by a transverse plane M. In this case, it can be understood that, seen in a plane perpendicular to the longitudinal direction L, the upper wall 12 has a curved profile between the common edge 18 and its free edge 16 and is incorporated in a circle.

[0064] In this configuration, the adapter 1 has a triangular cross section, seen in a plane perpendicular to the longitudinal direction L, the triangle of the cross section being defined by the free edge 14 of the side wall 10, the free edge 16 of the upper wall 12, and the common edge 18 between the side wall 10 and the upper wall 12. It is thus possible to define an interior space of the adapter 1, which is at least partially delimited by the side wall 10 and the upper wall 12. The interior space extends mainly in the form of a right prism with a triangular base.

[0065] Furthermore, the adapter 1 comprises an inner wall 20 extending at least partially in the inner space of the adapter 1. More specifically, the inner wall 20 extends in the inner space from the upper wall 12 on a plane substantially parallel to the longitudinal direction L and the vertical direction V. It should be understood that the inner wall 20 extends substantially parallel to the side wall 10.

[0066] According to the invention, the inner wall 20 participates in at least partially delimiting a receiving area 26 designed to receive the connector 8. The connector 8 is at least partially housed in the receiving area 26 when the adapter 1 is mounted on the connector 8.

[0067] In addition, more specifically Figure 3 and 4As shown, the adapter 1 comprises a plurality of walls participating in defining the receiving area 26, in particular the inner wall 20. More specifically, these walls extend in the form of a rectangle, extending in planes substantially perpendicular to the planes of extension of the adjacent walls. It can therefore be understood that the adapter 1 comprises a longitudinal wall 66 extending parallel to the inner wall 20, and two side walls 70 extending perpendicular to the longitudinal wall 66 and the inner wall 20 and between them.

[0068] Furthermore, once the connector 8 is mounted on the adapter 1, the connector 8 is at least partially positioned in the receiving area 26 of the adapter 1. In other words, the connector 8 is at least partially positioned between the inner wall 20 and the longitudinal wall 66, and between the side walls 70.

[0069] As previously mentioned, the adapter 1 is mounted to rotate on the connector 8 by means of a rotation device 58. This device comprises a plurality of elements which cooperate with each other and which are positioned firstly on the connector 8 and secondly on the adapter 1.

[0070] For example, Figure 3 and 4 As shown, the adapter 1 firstly comprises a male element 73 on the longitudinal wall 66 , which is configured to cooperate with a female element of the connector 8 , and secondly comprises a female element 75 for cooperating with a male element of the connector 8 .

[0071] More specifically, the male element is in the form of a tongue carrying a torus, and the female element is in the form of a hole in which the torus rotates about the axis of rotation R. The tongue of the adapter 1 extends, for example, in a plane that merges with the plane of extension of the longitudinal wall 66 and is delimited relative to said longitudinal wall 66 by at least one groove, advantageously at least two grooves, extending in a vertical direction V. In this configuration, the tongue is elastically deformable and at the same time movable about a direction of rotation parallel to the longitudinal direction L, thus allowing the adapter 1 to be mounted on the connector 8.

[0072] According to the present invention and Figures 3 to 5 As shown, the adapter 1 includes a locking device 22, which is designed to make the adapter 1 longitudinally integral with the arm 4 of the wiper system 6, and the locking device 22 is installed to pivot on the upper wall 12 around the pivot axis P. The locking device 22 includes a limiting device 24 for limiting its pivoting, and the limiting device 24 is supported against the inner wall 20.

[0073] More specifically, the locking device 22 comprises at least one push unit 28 which is integrated into the contour of the upper wall 20 and a blocking unit 30 which at least partially extends into a receiving receptacle 32 designed to receive the arm 4. After describing the locking device 22, a more detailed description of the receiving receptacle 32 will be provided.

[0074] like Figures 2 to 5 As shown, the push unit 28 extends in a form matching the shape of the upper wall 12 and is flush with the upper wall 12. The push unit 28 is also a unit of the locking device 22 on which the user applies force to allow the locking device 22 to pivot about the pivot axis P.

[0075] According to the present invention, the push unit 28 has a curved profile, seen in a cross section perpendicular to the longitudinal direction L, which is incorporated into the profile of the upper wall 12. In this case, it can be understood that the upper wall 12 and the push unit 28 each have a curved profile contained in the same circle.

[0076] The push unit 28 is surrounded by a groove 36 which separates the push unit 28 from the upper wall 12. It should be understood that the groove 36 passes through the upper wall 12 from side to side while delimiting the push unit 28. In this case, the groove 36 has a rectangular form.

[0077] In top view, the push unit 28 also has a substantially parallelepipedal form, with at least one upper side 38 and one lower side 40 extending parallel to the longitudinal direction L, and two transverse sides extending perpendicularly to the upper side 38 and the lower side 40 and substantially parallel to the transverse direction T. More specifically, the upper side 38 of the push unit 28 is positioned closer to the common edge 18 between the side wall 10 and the upper wall 12 than to the free edge 16 of the upper wall 12, while the lower side 40 is positioned closer to the free edge 16 of the upper wall 12 than to the common edge 18 between the side wall 10 and the upper wall 12.

[0078] Furthermore, the locking device 22 comprises at least one hinge 34 connecting the push unit 28 to the upper wall 12, thereby allowing the locking device 22 to pivot. The hinge 34 is located between the lower side 40 of the push unit 28 and the upper wall 12, the groove 36 extending mainly on the other three sides of the push unit 28. In this case, the hinge 34 is in the form of a bridge between the push unit 28 and the upper wall 12, the three elements thus forming a single-piece element, i.e. one of the elements cannot be separated without causing damage to one or more of the three elements.

[0079] like Figure 2 As shown, in this case the groove 36 extends partially between the underside 40 of the push unit 28 and the upper wall 12 , so that the pivoting of the push unit 28 is optimized.

[0080] Furthermore, the push unit 28 has an outer face 42 oriented toward the external environment of the adapter 1 and an inner face 44 oriented toward the internal space of the adapter 1, and the push unit 28 has a pattern 46 that facilitates attachment on its outer face 42. It should be understood that, due to the presence of this pattern 46, the user using the push unit will have an optimized attachment.

[0081] This pattern 46 is, for example, a texture of the outer face 42 of the pusher unit 28. However, pusher units 28 comprising other patterns 46 would not depart from the scope of the invention.

[0082] Furthermore, the upper wall 12 comprises at least one air disturbance device 72 which extends in the longitudinal direction L and opens outwardly of the adapter 1 .

[0083] according to Figure 2 In the example shown, the air disturbance device 72 is in the form of a channel.

[0084] According to an alternative example of the invention, the air disturbance means 72 are in the form of ribs.

[0085] The blocking unit 30 itself is a unit of the locking device 22 configured to come into contact with the arm 4 so that the adapter 1 is integrated with and / or released from the arm 4. It should be understood that it is this unit that interacts with the arm 4 in order to fix the adapter 1 thereto.

[0086] from Figure 5 As can be seen more specifically in FIG. 2 , the blocking unit 30 extends from the pushing unit 28 to the receiving receptacle 32 , the blocking unit 30 comprising a bent portion 74 and a free end 76 which is positioned in the receiving receptacle 32 when the locking unit is in position to lock the adapter 1 to the arm 4 .

[0087] It should be understood that in this case, the curved portion 74 firstly includes a first portion extending from the push unit 28 on a first plane, and secondly includes a second portion extending toward the free end 76 on a second plane intersecting the first plane, and the curved portion 74 includes a connecting portion connecting the first portion to the second portion. For example, the first plane is parallel to the longitudinal direction L and the vertical direction V, and the second plane extends parallel to the longitudinal direction L and the transverse direction T. In addition, the curved portion 74 may include at least one supporting wall 78, which optimizes the rigidity of the curved portion 74.

[0088] The free end 76 itself is in the form of a shaft extending mainly in the longitudinal direction L.

[0089] According to the invention, the restriction device 24 forms part of the blocking unit 30. More specifically, the restriction device 24 and the blocking unit 30 form a one-piece assembly, i.e., the restriction device 24 and the blocking unit 30 cannot be separated from each other without causing destruction of the restriction device 24 and / or the blocking unit 30. In this case, the restriction device 24 extends the free end 76 longitudinally toward the receiving area 26. In other words, the free end 76 comprises a protrusion that extends the axis forming the free end 76 longitudinally toward the receiving area 26 and that serves as the restriction device 24.

[0090] In this case, the limiting device 24 has an end face 48 parallel to the transverse direction T and the vertical direction V, and a stop face 50 intersecting the end face 48 and facing the inner wall 20. It is also understood that the blocking unit 30 is longitudinally delimited by the end face 48 of the limiting device 24.

[0091] Furthermore, the inner wall 20 has a contact surface facing the limiting device 24 and a guide surface which participates in delimiting the receiving area 26 .

[0092] like Figure 6 As shown, Figure 6 is Figure 3 In the cross section provided on the cross-sectional plane N shown, the limiting means 24 bear against a contact surface of the inner wall 20 so as to limit the displacement of the locking means 22 during use, thereby releasing the adapter from the arm 4 .

[0093] In other words, the limiting means 24 is more particularly formed by a stop face 50 which intersects the end face 48 and faces a contact face of the inner wall 20. Furthermore, the stop face 50 and the contact face each extend on a plane parallel to the longitudinal direction.

[0094] The stop surface 50 of the limiting device 24 participates in defining the pivoting range of the locking device 22. More specifically, when the locking device 22 pivots about the pivot axis P, the stop surface 50 of the limiting device 24 contacts the contact surface of the inner wall 20 participating in defining the receiving area 26, thereby preventing the locking device 22 from pivoting.

[0095] In other words, the limiting device 24 for limiting the locking device 22 prevents the locking device 22 from pivoting in at least one of its pivoting directions. In this case, it can be understood that the limiting device 24 can prevent the locking device 22 from pivoting too far, for example, by a stop between the stop surface 50 of the limiting device 24 and the inner wall 20, thereby limiting the risk of fracture of the components of the adapter 1 and / or the arm 4.

[0096] According to the invention, the locking device 22 pivots about the pivot axis P over a maximum angle of 20° measured between the extension planes of the stop surface 50 and the contact surface of the inner wall 20 when the free end 76 is located in the receiving receptacle 32 .

[0097] Preferably, the pivot angle of the locking device 22 is at most 15°.

[0098] Even more preferably, the pivoting angle of the locking device 22 is a maximum of 10°.

[0099] Furthermore, the adapter 1 comprises at least one reinforcement 52 extending between the inner wall 20 and the side walls 10 and / or the upper wall 12. In particular, the reinforcement 52 comprises, for example, a wall extending mainly in a plane substantially perpendicular to the longitudinal direction. The reinforcement 52 makes it possible to reinforce the structure of the adapter 1 and optimize its rigidity.

[0100] like Figure 3 As shown, the reinforcement 52 comprises an opening 54 which participates in at least partially limiting the receiving receptacle 32. It should be understood that the opening 54 is designed to receive at least a portion of the rod 60 of the arm 4.

[0101] In addition, if Figures 3 to 5 As shown, the receiving receptacle 32 is at least partially defined by the sleeve 64 and the side wall 10 and / or the upper wall 12, in addition to being defined by the opening 54 of the reinforcement member 52. In this arrangement, more specifically, Figure 4 As shown, the opening 54 of the reinforcement 52 and the sleeve 64 are aligned in a direction parallel to the longitudinal direction L, so that the rod 60 of the arm 4 extends in the longitudinal direction L through the sleeve 64 and the opening 54 of the reinforcement 52 .

[0102] According to the invention, the receiving receptacle 32 is laterally offset relative to the receiving area 26. In other words, the position of the receiving receptacle 32 is offset relative to the receiving area 26 in the transverse direction T. The position of the receiving receptacle 32 is also offset relative to the receiving area 26 in the vertical direction V.

[0103] More specifically, the receiving receptacle 32 is closer to the side wall 10 than the receiving area 26. In other words, the receiving receptacle 32 is located between the receiving area 26 and the lateral area 10. More specifically, the receiving receptacle 32, the common edge 18 and the receiving area 26 are aligned in the medial direction, and the receiving receptacle 32 is located between the common edge 18 and the receiving area 26.

[0104] Thus, it can be defined that the receiving receptacle 32 extends in a main extension plane parallel to the longitudinal direction and the median direction, which is visible in the middle of said receiving receptacle 32 and which intersects the receiving area 26 .

[0105] Furthermore, at least one end of the rod 60 has a shape complementary to the receiving housing 32 of the adapter 1, the rod 60 having a notch 62 cooperating with the locking means 22 so as to longitudinally block the position of the adapter 1 on the rod 60. It will be understood that the free end 76 is located in the notch 62 of the rod 60, thereby locking the rod 60 in the receiving housing 32.

[0106] It will be appreciated that to unlock the position of the adapter 1 on the arm 4, the locking means 22 are pivoted about the pivoting direction until the limiting means 24 abut against the inner wall 20. This pivoting is sufficient to unlock the position of the adapter 1 relative to the arm 4 while limiting the risk of the locking means 22 breaking.

[0107] However, the invention is not limited to the devices and configurations described and shown here, but also extends to any equivalent devices and configurations, and any technically operable combination of these devices.
