(7) In the rest of the description, the designations longitudinal or transverse refer to the orientation of a connector of a connecting device of a wiping system. The longitudinal direction corresponds to a longitudinal direction of extension of the connector, this longitudinal direction being parallel to an axis Ox of an orthonormal frame of reference for example depicted in FIG. 1. A transverse direction corresponds to a direction parallel to an axis Oy of this orthonormal frame of reference, the axis Oy being perpendicular to the axis Ox. A vertical direction corresponds to a direction parallel to an axis Oz of the orthonormal frame of reference, the axis Oz being perpendicular to the axis Ox and to the axis Oy.

(8) The longitudinal sections mentioned below are realized in section planes in which the axes Ox and Oz of this orthonormal frame of reference are inscribed.

(9) With reference to FIG. 1, a motor vehicle is commonly equipped with a wiping system 1 for evacuating water and/or dirt present on a glazed surface, notably a rear window or a windscreen of the motor vehicle. The wiping system 1 comprises a driving arm 2 that is able to carry out an angular back-and-forth movement along and over the glazed surface. The driving arm 2 can comprise a driver, not illustrated here, intended to provide a mechanical connection between the driving arm 2 and a drive shaft for driving the driving arm 2 in rotation.

(10) The wiping system 1 also comprises a wiper blade 4, which extends mainly along a longitudinal axis X parallel to the axis Ox of the orthonormal frame of reference depicted in FIG. 1. The wiper blade 4 comprises at least one air deflector 5 and a blade rubber 6, which are joined together by a structural element 7 of the wiper blade 4, the latter thus not having yokes. Such a structural element 7 can be formed for example by a single bending member, or by a plurality of bending members, or by a support in which one or more bending members are inserted.

(11) The air deflector 5 is provided to convert a pressure applied by an airflow flowing along the glazed surface into a pressing force pressing the wiper blade 4 against the glazed surface of the motor vehicle. The blade rubber 6 is the part of the wiper blade 4 that is in direct contact with the glazed surface and is configured to evacuate the water and/or dirt present thereon. The air deflector 5, the blade rubber 6 and the structural element 7 form a semi-rigid assembly carried by a connecting device 8, interposed between the driving arm 2 and the wiper blade 4.

(12) This connecting device 8 comprises a connector 9 in which an adapter—not shown here—is housed and on which a cover 11 is mounted in a rotatable manner. The adapter conventionally comprises a transverse shaft configured to receive a hook 12 of an end part 13 of the driving arm 2.

(13) The connecting device 8 thus ensures a pivoting mechanical connection between the end part 13 of the driving arm 2 and the wiper blade 4. This connecting device 8 also makes it possible to separate the wiper blade 4 from the driving arm 2 in order to replace the wiper blade 4.

(14) In addition to an aesthetic function, the cover 11, which is mounted in a rotatable manner on the connector 9, is intended to lock the end part 13 of the driving arm 2 on the adapter of the connecting device 8. This cover 11 can thus take up a first, “closed” position, in which it locks this end part 13 of the driving arm 2, or a second, “open” position, allowing the insertion of this end part 13 into the connecting device 8.

(15) According to the present invention, the connecting device 8 comprises at least one holding device for holding the cover 11 on the connector 9 in at least one of these two positions. This holding device for holding the cover 11 on the connector 9 will be described in more detail later in the description.

(16) FIGS. 2 and 3 illustrate the first position of the cover 11 on the connector 9 and the second position of this cover 11 on the connector 9, respectively.

(17) The first position of the cover 11, illustrated in FIG. 2, is the “closed” position, namely the position which allows the driving arm to be locked on the wiper blade comprising the connector 9. From this first position, the cover 11 can reach its second position by virtue of rotation in a first direction of rotation S1, as shown in this FIG. 2.

(18) The second position of the cover 11, illustrated in FIG. 3, is the “open” position, namely the position of this cover 11 which allows the insertion of the hook of the end part of the driving arm into the adapter housed in the connector 9. From this second position, the cover 11 can reach its first position by virtue of rotation in a second direction of rotation S2, opposite to the first direction of rotation S1, as shown in FIG. 3.

(19) In order to make it easier to read the figures, the adapter is not shown.

(20) The cover 11 comprises two side walls 110, which are symmetric with respect to a longitudinal mid-plane of the connector 9 and are connected together by an upper wall 111. A “longitudinal mid-plane” is understood to be a plane that is parallel to the plane Oxz of the orthonormal frame of reference and passes through a centre of the connector 9, i.e. this longitudinal mid-plane is disposed at an equal distance from each of the side walls 110 of the cover 11.

(21) Each of the side walls 110 of the cover 11 comprises a shared edge 10 with the upper wall 111 and a free edge 30 that is intended to be in contact with the connector 9.

(22) In order to allow the insertion of the driving arm into the connecting device 8, the upper wall 111 of the cover 11 comprises an opening 112, which can be seen notably in FIG. 2. This opening 112 is also configured to allow the closure of the cover 11 once the end part of the driving arm has been inserted into the connecting device 8. As is shown in FIG. 2, this opening 112 extends between two opposite edges of the upper wall 111, these two opposite edges being the shared edges 10 between the upper wall 111 and each side wall 110.

(23) As illustrated in FIG. 2, the cover 11 extends mainly in a first longitudinal direction D1 when it is in its first position, this first direction D1 being parallel to the axis Ox of the orthonormal frame of reference.

(24) In this first position, the cover 11 comprises a first longitudinal end 113 and a second longitudinal end 114, at the opposite end from the first longitudinal end 113. As can be seen for example in this FIG. 2, the first longitudinal end 113 of the cover 11 has a rounded shape.

(25) The first longitudinal end 113 and the second longitudinal end 114 of the cover 11 each have a shape complementary to that of the connector 9 on which they are disposed. It will then be understood that the rounded shape of the first longitudinal end 113 of the cover 11 makes it easier to rotate the cover 11 with respect to the connector 9.

(26) As can be seen in these FIGS. 2 and 3, the connector 9 also extends mainly in the first longitudinal direction D1 and comprises a coupling zone 14 for coupling the connector 9 to the structural element of the wiper blade. This coupling zone 14 comprises for example two skirts 140, 141, which are configured to enclose this structural element of this wiper blade.

(27) The connector 9 has a first longitudinal end 90 and a second longitudinal end 91, at the opposite end from the first longitudinal end 90 in the first longitudinal direction D1.

(28) As can be seen in FIG. 3, the connector 9 comprises two flanks 19, which are symmetric with respect to the longitudinal mid-plane of the connector 9, and which extend parallel to one another and towards the cover 11. These flanks 19 delimit a space 20 configured to receive the adapter of the connecting device and are entirely covered by the cover 11 when the latter is in its first, “closed” position.

(29) The second longitudinal end 91 of the connector 9 comprises an upright wall 21 against which the second longitudinal end 114 of the cover 11 bears, as shown notably in FIG. 2.

(30) As mentioned above, the cover 11 is mounted in a rotatable manner on the connector 9. The connecting device 8 thus comprises a pivot connection 15 between this cover 11 and this connector 9, this pivot connection 15 being realized by cooperation between the first longitudinal end 90 of the connector 9 and the first longitudinal end 113 of the cover 11.

(31) This pivot connection 15 between the cover 11 and the connector 9 comprises at least one trunnion 17 and at least one bearing 16 in which an orifice 18 configured to receive the trunnion 17 is formed. Advantageously, the trunnion 17 and the orifice 18 in the bearing 16 of the pivot connection 15 have complementary shapes allowing one to rotate with respect to the other.

(32) In this case, the pivot connection 15, which can be seen better in FIG. 3, comprises two bearings 16 produced as one with the connector 9 and two trunnions 17 produced as one with the cover 11. An orifice 18 is formed in each bearing 16, these orifices 18 being respectively configured to receive one of the trunnions 17 formed on the cover 11. The two bearings 16 and the two trunnions 17 are symmetric with respect to the longitudinal mid-plane of the connector 9.

(33) According to an exemplary embodiment that is not illustrated here, the pivot connection comprises a single bearing produced as one with the connector and a single trunnion produced as one with the cover, this trunnion being configured to be received in an orifice formed in the bearing of the connector. It will be understood that, according to this exemplary embodiment, the bearing and the trunnion are formed on one and the same side with respect to the longitudinal mid-plane of the connector.

(34) As illustrated in FIG. 3, the cover 11 extends, in its second position, mainly in a second direction D2 perpendicular, or approximately perpendicular, to the first direction D1. This second direction D2 is, according to an example shown in this FIG. 3, a vertical direction, i.e. a direction parallel to the axis Oz of the orthonormal frame of reference.

(35) As illustrated notably in FIG. 3, the cover 11 is rotatable about a third direction D3 perpendicular to the first direction D1 and the second direction D2. In other words, this third direction D3 is parallel to the axis Oy of the orthonormal frame of reference as shown in these figures and forms an axis of rotation of the pivoting connection 15.

(36) As mentioned above, the connecting device according to the present invention comprises at least one holding device for holding the cover on the connector, which will now be described in more detail with reference to FIGS. 4 to 7.

(37) FIG. 4 thus illustrates an exemplary embodiment of this holding device 22, which is disposed at the pivot connection 15 between the cover 11 and the connector 9. According to this exemplary embodiment, the holding device 22 comprises a rib 23 and at least two grooves referenced 240, 241, the rib 23 being intended to be received in either one of these grooves 240, 241.

(38) This FIG. 4 is a side view of this pivot connection 15 in which the cover 11 has been rendered partially transparent in order to make the holding device 22 for holding the cover 11 on the connector 9 visible.

(39) The objective of this holding device 22 is to hold the cover 11 either in its first, “closed” position or in its second, “open” position. It will thus be understood that this holding device 22 allows the cover 11 to rotate between these two positions and only locks the cover 11 when the latter is in one or the other of these positions.

(40) The expression “locks the cover” is understood to mean that when the cover 11 is in its first position or in its second position, the holding device 22 limits the rotation of this cover 11 in the first direction of rotation S1 and in the second direction of rotation S2. In order to pass from one position to the other, the intervention of a user is required, who has to apply a force in the first direction of rotation S1 or in the second direction of rotation S2 depending on the position that he wishes to reach, such that the rib 23 can leave the groove in which it is received.

(41) The holding device 22 makes it possible notably to avoid excessive rotation during the opening of the cover 11, that is to say when this cover 11 pivots in the first direction of rotation S1. This is because excessive rotation of this cover 11 could damage it and make it unusable.

(42) The holding device 22 also makes it easier to insert the end part of the driving arm by allowing the cover 11 to be held in its second, open position. Thus, the cover 11 cannot flap back spontaneously during the insertion of this driving arm. Indeed, such spontaneous flapping back of the cover 11 is not desirable since this would lead to a reduction in size of the opening 112 with regard to the end part of the driving arm, making the insertion thereof particularly complicated.

(43) As illustrated in FIG. 4, the holding device 22 is arranged at the pivot connection 15 between the connector 9 and the cover 11, one part of this holding device 22 being formed on at least one of the bearings 16 of the connector 9, and another part of this holding device 22 being formed on the cover 11, and advantageously close to the trunnions 17 received in the orifices 18 formed in the bearings 16, as described above. More specifically, the other part of this holding device 22 is distributed around the trunnions 17.

(44) As mentioned above, the holding device 22 according to the exemplary embodiment illustrated in FIG. 4 comprises a first groove 240 and a second groove 241. The first groove 240 and the second groove 241 are intended to hold the cover in its first, closed position and in its second, open position, respectively. A third groove 242 can also be formed at the pivot connection 15, this third groove 242 being a guide groove, configured to make it easier to fit the cover 11 on the connector 9.

(45) According to the example illustrated in FIG. 4, this third groove 242 is formed in continuation of the first groove 240.

(46) When the user wishes to mount the wiper blade on its driving arm, he firstly has to pivot the cover 11 such that the latter takes up its second position. By exerting sufficient force, the user can cause the rib 23 to leave the first groove 240, and then pivot this cover 11 in the first direction of rotation S1 described above.

(47) During the rotation of the cover 11 with respect to the connector 9, the rib 23 moves between the first groove 240 and the second groove 241, as is shown in FIG. 4. It will be understood that, in order to allow this rotation, the side walls 110 of the cover 11 are made of an elastically deformable material, i.e. that these side walls 110 are configured to move apart in order to allow the rib 23 to leave the first groove 240 in which it is received. Once the rotation has been carried out, the side walls 110 of the cover 11 are configured to return to their initial spacing in order to allow the rib 23 to be placed in the second groove 241, this second groove 241 being configured to lock the cover 11 in its second, open position.

(48) Once the driving aim has been mounted in the connecting device by the end part being introduced into the opening in the cover 11, the user can pivot the cover 11 in the second direction of rotation S2 until the rib 23 is again received in the first groove 240. As described above, when the rib 23 is received in the first groove 240, the cover 11 is held in its first, closed position, this first position of the cover 11 making it possible to at least partially lock the driving arm in the connecting device. It will be understood that the rotation steps for passing from the first position to the second position are similar to those for passing from the second position to the first position.

(49) Thus, a method for fitting the cover 11 on the connector 9 can comprise a step in which the rib 23 formed on the cover 11 is received in the third groove 242, and a step of moving the cover 11 in translation with respect to the connector 9 until the trunnions 17 formed on the cover 11 are respectively received in one of the orifices 18 formed in the bearings 16 of the connector 9.

(50) The rib 23 and the grooves 240, 241, 242 forming the holding device for holding the cover 11 on the connector 9 will now be described in more detail with reference to FIGS. 5 and 6.

(51) FIG. 5 illustrates the first longitudinal end 113 of the cover 11, as seen in a cross section passing through a longitudinal mid-plane of this cover 11. As a reminder, a “longitudinal mid-plane” is understood to mean a plane that is parallel to the plane Oxz of the orthonormal frame of reference and passes through a centre of the cover 11. This FIG. 5 thus reveals one of the trunnions 17 of this cover 11. As mentioned above, the two trunnions of this cover 11 are symmetric, and it will thus be understood that the description of the trunnion 17 illustrated in FIG. 5 is transferable to the other trunnion, which is not visible in this FIG. 5.

(52) This trunnion 17 has a substantially circular shape and comprises a chamfer 25 configured to make it easier to insert this trunnion 17 into the orifice formed in at least one of the bearings of the connector. According to an exemplary embodiment illustrated in FIG. 5, the rib 23 is produced as one with the trunnion 17 and extends from this trunnion to the free edge 30 of the corresponding side wall 110. More specifically, this rib 23 is formed in line with the chamfer 25 of this trunnion 17. As is shown, this rib 23 is rectilinear and extends radially with respect to the axis of rotation D3 of the pivot connection. The rib 23 also comprises two parallel flanks 230, 231.

(53) For its part, FIG. 6 illustrates the first longitudinal end 90 of the connector 9 on which one of the bearings 16 of the connector 9 is formed, seen in a cross section on the longitudinal mid-plane of this connector 9. As described above, this bearing 16 comprises the orifice 18 configured to receive one of the trunnions of the cover.

(54) According to an exemplary embodiment illustrated in this FIG. 6, three grooves 240, 241, 242 are formed in this bearing 16. As mentioned above, the first groove 240 and the second groove 241 are configured to hold the cover in its first position or in its second position, respectively, while the third groove 242 makes it possible to guide the cover over the connector 9 while it is being fitted.

(55) Each of these grooves 240, 241, 242 is formed by a rectilinear cutout which extends radially from the orifice 18 formed in the bearing 16. As illustrated, the orifice 18 is delimited by a circular contour 180 which has a chamfer. It will be understood that this chamfer extends around the entire periphery of the orifice 18. Advantageously, this chamfer makes it easier to insert the trunnion into this orifice 18 in order to form the pivot connection.

(56) Each of these grooves 240, 241, 242 is delimited by a first edge 26 and by a second edge 27 and comprises a bottom 28. It will be understood that in order to allow a part of a flank of the rib to be in abutment against at least a part of one of the edges 26, 27 of one of these grooves 240, 241, 242, a depth of each groove, measured between the bottom 28 of the groove 240, 241, 242 in question and one of its edges 26, 27 is equal to or greater than a thickness of the rib, this thickness of the rib being measured along a straight line parallel to the axis Oy of the orthonormal frame of reference. Thus, when the rib is received in one of the grooves 240, 241, 242, the side wall of the cover comprising the trunnion from which the rib extends is disposed in contact with the bearing 16 in which these grooves 240, 241, 242 are formed.

(57) As is shown in FIG. 6, the first groove 240 and the second groove 241 together delimit a first angular sector θ of the bearing 16. According to the exemplary embodiment illustrated in FIG. 6, this first angular sector is approximately equal to 90°. In other words, the first edge 26 and the second edge 27 of the first groove 240 extend mainly in directions perpendicular to directions in which the first edge 26 and the second edge 27, respectively, of the second groove 241 mainly extend.

(58) For its part, the third groove 242 is formed in all positions of a second angular sector θ′, on the opposite side from the first angular sector θ with respect to the axis of rotation D3 of the pivot connection 15. According to the exemplary embodiment illustrated in FIG. 6, the third groove 242 is formed in continuation of the first groove 240, namely at the limit of the second angular sector θ′. Thus, when the cover is mounted on the connector, this cover is directly inserted in its first position.

(59) According to an exemplary embodiment that is not illustrated here, the rib can be formed on at least one of the bearings of the connector and at least one groove can, for its part, be formed close to at least one of the trunnions formed on the cover. According to this exemplary embodiment, the rib then formed on the bearing(s) of the connector is configured to cooperate with the at least one groove formed close to the trunnion(s), in the same way as described above.

(60) According to a refinement of the present invention, a member 29 can be designed to increase the force for rotating the cover with respect to the connector.

(61) An exemplary embodiment of this member 29 designed to increase the rotating force is illustrated in FIG. 7. This FIG. 7 is a detail view of the other bearing 16 of the connector 9, that is to say of the bearing 16 that is not shown in FIG. 6. As mentioned above, these two bearings 16 are symmetric with respect to the longitudinal mid-plane of the connector.

(62) As can be seen in FIG. 7, the member 29 designed to increase the force for rotating the cover with respect to the connector is realized by an inclined wall 290 formed on the bearing 16, between the first groove 240 and the second groove 241. This inclined wall 290 notably allows the side walls of the cover to be spaced apart gradually as it is rotated on the connector 9.

(63) Advantageously, this inclined wall 290 also allows the user to better control the force applied to the cover, allowing him to be provided with feedback during the rotation of this cover on the connector. In other words, the closer the user gets to the second groove 241, the more force needs to be applied to the cover in order to turn it. Moreover, when the rib formed on the cover passes over the first edge corner 26 of this second groove 241, the side walls of the cover return to their initial position suddenly, thereby clearly indicating to the user that the cover has reached its second position, ready for mounting the wiper blade on the driving arm.

(64) Thus, the contour 180 delimiting the orifice 18 formed in the bearing 16 has different thicknesses. As shown in FIG. 7, this contour 180 is delimited by a first edge corner 181 and by a second edge corner 182 that are opposite one another along the axis of rotation D3 of the pivot connection.

(65) As illustrated, a first thickness e1 is greater than a second thickness e2 of this contour 180. These thicknesses e1 and e2 are both measured between the first edge corner 181 and the second edge corner 182 of this contour 180, in a direction parallel to the axis of rotation D3 of the pivot connection. The first thickness e1 is measured close to the second groove 241, while the second thickness e2 is measured close to the first groove 240.

(66) It will thus be understood that the force to be applied during the rotation of the cover in the first direction of rotation, namely to open this cover, is greater than the force to be applied during the rotation of this cover in the second direction of rotation, namely to close this cover.

(67) It will also be understood that the force to be applied to remove the rib from the first groove 240 is less than the force to be applied to remove this rib from the second groove 241.

(68) This gradual slope can also be realized in the opposite direction, thereby making the required force greater in the second direction of rotation.

(69) It will be understood that this gradual slope is only one exemplary embodiment of the member designed to increase the force for rotating the cover with respect to the connector and that any other member that obtains this same effect is also conceivable.

(70) It will be understood from the above that the present invention thus makes it easier to fit a cover on a connector of a connecting device of a wiping system for a vehicle and makes it possible to hold this cover in position with respect to the connector in order to make it possible, firstly, to insert a driving arm into this connecting device and, secondly, to lock this driving arm in this connecting device, while avoiding the risk of excessive rotation of the cover with respect to the connector, which could damage this cover.

(71) The invention is not limited to the means and configurations described and illustrated herein, however, and also extends to all equivalent means or configurations and to any technically operational combination of such means. In particular, the shape and dimensions of the rib and/or of the grooves of the holding device for holding the cover on the connector can be modified without detriment to the invention, as long as they provide the functionalities described in the present document.
