    The present invention relates to wiping systems for a motor vehicle, and more particularly relates to an adapter which constitutes such a wiping system.
    A wiping system, commonly referred to as windshield wipers, for a motor vehicle is designed to remove, by sweeping, liquids and dirt that can disturb the vision that a driver of a motor vehicle has of his environment. This wiping system generally comprises a drive arm which performs an angular back-and-forth movement around an axis of rotation, and an elongated wiping brush equipped with a scraper blade made of an elastic material. By rubbing against a glazed surface, front or rear, of the motor vehicle, the scraper blade sweeps the water and a certain number of dirt from it, and evacuates them outside the driver's field of vision.
    Whatever the configuration of the wiper blade, that is to say either a wiper blade comprising articulated stirrups which retain the scraper blade in several distinct zones, or a wiper blade comprising a metal blade which maintains the scraper blade over its entire length, the wiper blade is attached to an end portion of the drive arm by means of a connection device which comprises a connector mounted integral with the wiper blade.
    In a first known connection mode, an adapter, able to be assembled with the connector of the wiper blade, is mounted so that it can tilt about a fixing axis on the end part of the drive arm. This first connection method is commonly used for windshield wipers intended for glazed surfaces located at the front of the motor vehicle. In a second known connection mode, the connector is connected to a shaft secured to the drive arm. This second connection mode is commonly encountered in windshield wipers intended for glazed surfaces located at the rear of the motor vehicle.
    A general problem in the field lies in the need to correctly mount the wiper blade on the drive arm. An incorrectly mounted wiper blade can become a potential hazard if it separates from the drive arm, particularly under the action of centrifugal force generated by the rotational movement of the drive arm. In such a situation, the wiper blade can be ejected onto a user, onto another vehicle or onto the road, thus representing a danger.
    It is therefore desirable to have a mounting system which turns out to be simple to assemble while making it possible to ensure secure retention of the wiper blade. More particularly, it is desirable to have an adapter capable of cooperating effectively and sustainably with an end portion of the drive arm which is likely to be of various conformation.
    An object of the present invention is to provide an adapter which is designed to be mounted easily, without risk of error or incomplete mounting.
    An adapter of the present invention is an adapter for connecting a wiper blade to a drive arm of a vehicle wiping system. The adapter comprises a head and a body held together by means of a fixing device, the head having a “U” section formed by at least one upper wall from which the at least two side walls, the body having a “U” section formed by at least one upper panel from which at least two side panels originate. The adapter includes at least one member for guiding the head relative to the body.
    This configuration has the advantage of simplifying the assembly of the adapter connecting the drive arm to the wiper blade. This increased simplicity therefore reduces the risk of assembly errors, and therefore the risk of ejection mentioned above.
    The adapter object of the invention has the advantage of being particularly well suited to a drive arm whose end part is shaped like a "U" with a hole above and grooves on the sides.
    The adapter advantageously includes at least any of the following characteristics, taken alone or in combination:
    the head and the body are parts made separately and connected to each other by the fixing device, such a fixing device ensures a reversible mechanical connection between the body and the head, the head is removable on the body, the guide member ensures alignment of the head with respect to the body, so as to operate the mechanical connection generated by the fixing device, the "U" section of the head delimits an internal space configured to receive at least partially the body, and advantageously only a part of the body, the fixing device is a combination of complementary shapes between the head and the body. The head carries a first element which is arranged to collaborate with a second element carried by the body, the collaboration of the two elements ensuring the retention of the head relative to the body, the guide member comprises at least one tab which extends in at least one cavity, the tab is formed on the body of the adapter, the cavity being formed in the head, the tab is formed on the head of the adapter, the cavity being formed in the body, the guidance extends into the internal volume of the head. More particularly, the guide member extends from an internal face of the head, that is to say a face of the head facing the internal volume, the guide member comprises at least one tab. Advantageously, the guide member comprises two legs, each extending in a separate cavity. A lug extends into a cavity, until a free end of the lug meets a bottom of the cavity, the free end being the part of the lug opposite to the part coming from the adapter. Alternatively, the leg extends into the cavity, the contact between the head and the body being made by a contact between a base of the leg and a face of the side walls of the body, a section of the leg is complementary to a section of the cavity. The section of the tab is notably less than the section of the cavity which receives it, but without excessive play, the fixing device comprises a keyhole formed in a side wall of the head which cooperates with a pin which emerges from one face of the side wall of the body, the tab of the guide member extends in a longitudinal direction which is parallel to a direction of longitudinal extension of the keyhole, the longitudinal direction of the tab and of the keyhole are parallel to a longitudinal direction of the adapter, the longitudinal direction of the tab and the keyhole are perpendicular to a longitudinal direction of the adapter, the keyhole has a circular clearance and a channel connecting an edge of the head at circular clearance, the channel is bordered by at least one slot, the adapter comprises a means of connection in rotation with a connector secured to the wiper blade, l he body of the adapter comprises at least one locking device for hooking the adapter with an end part of the drive arm, the locking device takes the form of a button which emerges from the upper wall of the body, the finger being configured to cooperate with an orifice formed in an upper wall of the end part, the head is configured to cover an end band of the end part of the drive arm.
    The present invention also relates to a connection device formed by a connector and an adapter described above, the connector being a part rotatably mounted on the adapter and arranged to carry the wiper blade.
    The present invention also relates to a wiper blade comprising an adapter as described above or a connection device described above, such an adapter being able to be mounted on the wiper blade.
    The present invention further relates to a wiping system comprising a drive arm, a connector secured to a wiper blade and an adapter described above connecting the connector to the drive arm in rotation.
    The present invention finally relates to a method of assembling a wiping system comprising at least one step of assembling an adapter body on a connector, a step of assembling an end part d '' a drive arm on the adapter and a step of assembling a head of the adapter on the body of the adapter, the body receiving the head by a face chosen from a front face or an upper face of the body.

    In the figures, the names longitudinal, transverse, vertical, lateral, front, rear, left, right, upper, lower, refer to the orientation of a wiper blade 1 illustrated in FIG. 1. A longitudinal direction corresponds to a longitudinal axis X along which extends the wiper blade 1 and / or an adapter 2 of the present invention. A transverse direction corresponds to that of a transverse axis Y which is perpendicular to the longitudinal axis X. The denominations left and right are appreciated in relation to a position along the transverse axis Y, on both sides from the longitudinal axis X. A vertical direction, parallel to that of a vertical axis Z, is perpendicular to the longitudinal and transverse directions mentioned above. The upper or lower names refer to orientations parallel to the vertical axis Z, the lower name containing the plane of the windscreen. For the longitudinal directions, the external or internal denominations are assessed in relation to a pivot point of the wiper blade 1 on a drive arm 3 of the wiper blade 1, the internal denomination corresponding to the part where the arm drive 3 and a half brush extend, the external designation corresponding to the part where the other half brush extends.
    The directions mentioned above are illustrated in an orthonormal reference frame Oxyz represented in the figures. In this coordinate system, the axis Ox represents the longitudinal direction, the axis Oy represents the transverse direction, and the axis Oz represents the vertical direction.
    In FIG. 1, a motor vehicle is commonly equipped with a wiping system 4 for removing water and / or dirt present on a glass surface, in particular a rear window or a motor vehicle windshield. The wiping system 4 comprises the drive arm 3 which is capable of performing an angular back-and-forth movement along and above the glass surface.
    The wiping system 4 also includes the wiping brush 1 which extends along a main axis, called the longitudinal direction X parallel to the axis Ox. The wiper blade 1 comprises at least one air deflector 5 and a scraper blade 6. The air deflector 5 is designed to transform a pressure applied by a flow of air circulating along the glazed surface into a force of the wiper blade 1 against the glazed surface of the motor vehicle. The scraper blade 6 is the part of the wiping brush 1 in direct contact with the glazed surface to evacuate the water and / or the dirt present on the latter. The air deflector 5 and the scraper blade 6 form a semi-rigid assembly 7 which is carried by a connection device 8, interposed between the drive arm 3 and the semi-rigid assembly 7.
    The connection device 8 provides a mechanical connection between an end portion of the drive arm 3 and the wiper blade 1 and thus makes it possible to separate the wiper blade 1 from the drive arm 3, for replacement wiper blade 1.
    In general, the connection device 8 of the present invention comprises three parts, including two parts making up the adapter 2 and a connector 10, visible together in FIG. 2, which represents the adapter 2 of the present invention in position d 'use. In this position of use, the adapter 2 is attached to the end portion 9 of the drive arm 3, according to a method of the invention described below.
    The connector 10 is suitable for carrying the wiper blade 1 and is mounted for rotation on the adapter 2. The adapter 2 is designed to be fixed to the end part 9 of the drive arm 3. According to one embodiment of the invention, the adapter 2 and the connector 10 are produced by molding a synthetic material, for example a material from the family of Polyoxymethylenes, known by the acronym POM, or by molding a mixture of polymeric materials , for example a mixture of polymers from the family of polycarbonates and from the family of Acrylonitrile Butadiene Styrene, known by the acronym ABS. The connector 10 is in one piece. In other words, the connector is in one piece and can only be split into several pieces after destruction of the connector 10. The terminal part 9 is for example produced by folding a metal strip, such as a sheet steel, aluminum or the like or by molding a synthetic material.
    Referring to FIG. 3, the adapter 2 is extended in the longitudinal direction X and comprises at least one head 11 and a body 12.
    The head 11 and the body 12 each have a transverse profile shaped as a "U". In other words, according to a transverse section produced according to a cutting plane parallel to the Oyz plane, the head 11 and the body 12 comprise a transverse profile shaped as a "U". In other words, the head 11 comprises an upper wall 11a which forms the base of the "U" and two side walls 11b, in particular parallel or substantially parallel to each other and orthogonal or substantially orthogonal to the upper wall 11a, which form the branches of the "U", while the body 12 comprises an upper panel 12a which forms the base of the "U" and two side panels 12b, substantially parallel to each other and substantially orthogonal to the upper panel 12a, which form the branches of the "U" .
    The head 11 comprises a first part and a second part 15, the second part 15 being inclined relative to the first part.
    The “U” shape of the head delimits an internal space 38 arranged to receive at least part of the body 12. The upper wall 11a and the side walls 11b include an internal face 37. The internal face 37 is opposite internal space 38.
    The “U” shape of the body 12 delimits an internal volume 32 arranged to receive at least partially the connector 10 made integral with the wiper blade 1. The side panels 12b comprise an external face 34 and an internal face 35, the faces internal 35 facing the internal volume 32, the external face 34 being the face opposite to the internal face 35. The upper face 12a comprises an upper face 55 which is the face of the upper face 12a which is opposite to the face from which the sides emerge lateral 12b.
    The side panels 12b comprise a hole 19, of round section, arranged to receive a rotation means 18 visible in FIG. 6. Each side panel 12b comprises a hole 19, the two holes 19 being aligned along an axis parallel to the axis Oy and corresponding to the axis around which the wiper blade can rotate to follow the curvature of the glass surface to be wiped.
    The head 11 and the body 12 of the adapter 2 are arranged relative to one another by a guide member 40, visible in FIG. 4. This guide member 40 comprises a tab 42 and a cavity 50.
    In a first variant of adapter 2 according to the invention, the head 11 of the adapter 2 carries at least one tab 42, and in particular two tabs 42, collaborating with two cavities 50 disposed in the body 12 of the adapter 2.
    Referring to FIG. 4, illustrating a first example of this variant, the legs 42 and the cavities 50 extend in a longitudinal direction parallel to a longitudinal direction of the head 12. In other words, the legs 42 and the cavities 50 extend in a longitudinal direction parallel to the direction of longitudinal extension X of the adapter 2, and consequently of the wiper blade 1. The tabs extend in particular in a longitudinal direction 62.
    The tabs 42 extend in the direction of the body 12. The tab 42 includes a base. This base can have two different conformations.
    In the first configuration illustrated in FIG. 4, the legs 42 share the same base 46. This base 46 is arranged in the form of a wall 47 extending from the internal face 37 of the upper wall 11a and of the side walls 11b from the head 11. The legs 42 emerge from this low wall 47 and extend in the direction of the cavities 50.
    In the second conformation visible in Figure 5, each tab 42 has its own base 44. The base 44 extends from the internal face 37 of a side wall 11b of the head 11. The base 44 and the tab 42 are shaped as "L", projected onto a plane parallel to the plane of extension of the upper wall 1 the.
    Whatever the conformation of the base of the legs 42, the cavity 50 of FIG. 2 is in this example formed in the side panels 12b of the body 12 of the adapter 2. Advantageously, the body 12 comprises two cavities 50, formed in the side panels 12b of the body 12 of the adapter 2. More particularly, each side panel 12b comprises a cavity 50. The cavities 50 have an opening 52, for example of rectangular section, and extend longitudinally towards the rear of the body. The cavities 50 open onto a front face 54 of the body 12. The cavities 50 are not through and therefore include a bottom.
    The positioning of the head 11 relative to the body 12 is done by the collaboration between the legs 42, and the cavities 50, in particular the openings 52. The head 11 is notably attached to the body 12 from the front, that is ie by the translation of the head 11 in the direction of the body 12 in a direction parallel to the longitudinal direction X. In this example, the tabs 42 are pressed into the cavities 50 until contact between the front face 52 of the body 12 and the base 44, 46 of the legs 42 of the head 11. Alternatively, the legs 42 are pressed into the cavities 50 until a free end 43 of the legs 42 meets the bottom of the cavity 50.
    Still in FIG. 2, the head 11 and the body 12 are secured to each other by means of a fixing device 80. This fixing device 80 comprises at least one pin 84 and a hole for lock 82. The collaboration between a keyhole 82 and a pin 84 ensures the joining of the head 11 and the body 12. The joining is done by snap-fastening of the fixing device 80 around the pin 84.
    In the example described here, the fixing device 80 comprises a keyhole 82, arranged in the side walls 11b of the head 11. Advantageously, the fixing device 80 comprises two keyholes 82. Each side wall 1 lb comprises thus a keyhole 82. The keyhole 82 extends in a longitudinal direction 61. This longitudinal direction 61 is parallel to the longitudinal direction 62 of the tab 42.
    This keyhole 82 comprises a channel 86 joining a circular clearance 87. The channel 86 is formed in the side walls 11b of the head, and connects the circular clearance 87 to a rear edge 89 of the head 11. The section of the pin 84 is less than the circumference of the circular clearance 87. The channel 86 and the circular clearance 87 are through, that is to say that they connect the internal face 37 of the head 11 to an external face 39 of the head 11. In the example of the guide member 40 comprising tabs 42 with separate bases 44, the tabs 42 and the keyholes 82 are aligned on the same plane. In the example of the guide member 40 comprising tabs 42 with a common base 46, the keyholes 82 and the tabs 42 extend in two separate and parallel planes.
    In another embodiment of this variant of the invention, the channel 86 of the fixing device 80 is bordered on each side by a slot 88. The slot 88 is arranged to allow elastic deformation of the section 83 of the side walls 1 lb disposed between the channel 86 and the slot 88 considered. This elastic deformation makes it possible to lock the keyhole 82 around the pin 84 with which the keyhole 82 collaborates.
    The pin 84, of circular cylindrical shape, extends from the outer face 34 of the side panels 12b of the body 12. Advantageously, according to the example described here, the body 12 comprises two pins 84, each arranged on a side panel 12b of the body 12. The height of the pin 84, that is to say the dimension between the side panel 12b which carries the pin 84 and an end face 85 of the pin 84, is for example less than or equal to the thickness of the wall lateral 1 lb of the head 11. The thickness of the lateral wall 1 lb of the head 11 is the dimension between the internal face 37 and the external face 39 of the lateral wall 1 lb.
    The insertion of the legs 42 into the cavities 50 via the openings 52 makes it possible to position the channels 86 of the keyholes 82 in front of the pins 84 of the body 12, so as to allow the head 11 to snap into the body 12 The two parts of the adapter 2 are thus secured to one another. The fixing device 80 ensures the retention of the head 11 on the body 12.
    In a second example, visible in FIGS. 7 and 8, the legs 42 and the cavities 50 extend in a longitudinal direction perpendicular to the longitudinal direction of the head 11. In other words, the legs 42 and the cavities 50 extend in a longitudinal direction perpendicular to the longitudinal extension direction X of the adapter 2, and consequently of the wiper blade 1.
    As illustrated in FIG. 8, the tabs 42 extend from the inner face 37 of the upper wall 11a of the head 11.
    The cavities 50 open onto the upper face 12a of the body and extend into the side panels 12b. The cavities 50 have an opening 52 with a rectangular section, in any event complementary to the section of the tab 42 that the cavity 50 receives.
    The positioning of the head 11 relative to the body 12 is done via the guide member 40, by the collaboration between the legs 42 and the cavities 50, in particular the openings 52. The head 11 is notably attached to the body 12 by the high, that is to say by the translation of the head 11 in the direction of the body 12 in a direction parallel to the vertical direction Oz, which is a direction perpendicular to the longitudinal axis X and to the transverse axis Y. In this example, the legs 42 are pressed into the cavities 50 until contact between the upper face 12a of the body 12 and the internal face 37 of the upper wall 11a of the head 11. Alternatively, the legs 42 are pressed into the cavities 50 until contact between a free end 43 of the legs 42 meets the bottom of the cavity 50.
    The fixing device 80 is arranged differently from its arrangement in the first example of the adapter according to the invention. H comprises a keyhole 82, arranged in the side walls 11b of the head 11, the keyhole 82 comprising a channel 86 connecting a lower edge 51 of the side walls 1 lb, visible in FIG. 3, to a circular clearance 87 The channel 86 of the fixing device 80 is bordered on each side by a slot 88. The slot 88 is arranged to allow elastic deformation of the section 83 of the side walls 11b disposed between the channel 86 and the slot 88 considered. This elastic deformation makes it possible to lock the keyhole 82 around the pin 84 with which the keyhole 82 collaborates.
    The pins 84 of the fixing device 80 are arranged identically to their arrangement in the first example. In particular, they emerge in the same way from the side panels 12b of the body 12. They have the same circular cylindrical shape, and their circumference is less than that of the corresponding cylindrical clearance 87.
    According to a variant of the invention, the adapter can be shaped differently. This conformation is notably different in that the tab of the guide member is carried not by the head of the adapter, but by the body of the adapter, the head comprising at least one cavity.
    In a first example of this variant, the tab and the cavity extend in a longitudinal direction parallel to a longitudinal direction of the head, that is to say along the longitudinal direction X of the adapter. The guide member includes in particular two tabs, arranged on the front face of the body of the adapter.
    More particularly, the legs extend from the front face of the side panels of the body. They collaborate with two cavities arranged in the head and arranged in a low wall extending from the inner face of the upper walls and the side walls of the head.
    In a second example of this variant, the legs and the cavity extend in a longitudinal direction perpendicular to the longitudinal direction of the head, that is to say perpendicular to the longitudinal direction X of the adapter. The legs extend from the upper wall of the body. The legs collaborate with two cavities arranged in the head and arranged in the upper wall of the head. The cavities are through and thus each has two outlets which open onto the internal space of the head. In an alternative example, the cavities are not through, and are therefore delimited by a bottom.
    In both cases, the adapter includes a fixing device arranged identically to the first variant. Thus, the fixing device is arranged identically to its configuration in the first variant. H comprises two keyholes each comprising a channel and a circular clearance, and which collaborate with two pins. The pins are circular cylindrical in shape and extend from the outside of the side panels of the body. The height of the pin is for example less than or equal to the thickness of the side wall of the head. The head is fixed to the body by snapping the keyholes around the pins. In the case of the adapter, the guide member and the cavity of which extend in a longitudinal direction perpendicular to the longitudinal direction of the head, each channel is flanked by two slots.
    Whichever variant is considered, once mounted one on top of the other, the head 11 and the body 12 are aligned. The upper wall 11a and the upper panel 12a extend in distinct and parallel planes, and each of the side walls 11b and side panels 12b extend in distinct and parallel planes with one another.
    The adapter 2 also comprises a rotation means 18 arranged to connect the adapter 2 to the connector 10, while allowing rotation of one relative to the other. This rotation means 18 allows this rotation about the transverse axis Y. The rotation means 18 can be formed by a pair of strands which emerge in the hollow structure of the adapter 2. They can also be formed bearings in the side walls 11b, as illustrated in the figures.
    Advantageously, the rotation means 18 is arranged on the adapter 2 behind the pins 84, that is to say that the pins 84 are arranged between the rotation means 18 and the front face 54 of the body 12.
    The body comprises a blocking device 16, arranged to collaborate with an orifice 90 arranged on the end part 9 of the drive arm 3. This blocking device 16 takes the form of a button 17 having lateral faces 21.
    The end part 9 of the drive arm 3, visible in FIGS. 2, 6 or 9, is arranged in a "U" shape, seen in a cross section parallel to the Oyz plane. The terminal part 9 comprises a first wall 95 forming the base of the "U" and two second walls 96 substantially parallel and forming the branches of the "U".
    The first wall 95 is provided with an orifice 90, the latter being centered laterally on the first wall 95 of the terminal part 9. The first wall 95 and the second walls 96 are delimited in the front part by a front edge 92 which has a transverse profile in "U".
    The second walls 96 each have an internal surface 97 which defines, with the first wall 95, an internal volume 99 of the terminal part 9. The front edge 92 is provided with two grooves 91, visible in FIG. 2, which are formed longitudinally inside the second walls 96. The two grooves 91 are formed opposite one another through a respective second wall 96. Each groove 91 has an opening 93 formed in the front edge 92.
    The wiping system 4 according to the invention is assembled according to the example described below. The assembly described here is in no way limiting, the method can include additional steps, alternative steps, or these steps can be done simultaneously or in a different order.
    The connector 10 is connected in rotation to the body 12 by the rotation means 18. More particularly, the connector 10 is inserted in the internal volume 32 of the body 12 and secured by the insertion of the rotation means 18 in the holes 19 arranged in the side panels 12b of the body 12.
    The body 12 of the adapter 2, equipped with the connector 10, is then inserted into the interior volume 99 of the terminal part 9 of the drive arm 3. More particularly, the button 17 is inserted into the orifice 90.
    The positioning of the head 11 on the body 12 is done in the first variant by a translational movement parallel to the longitudinal axis Ox. The mounting of this variant is illustrated in FIG. 6. In the second variant, the positioning of the head 11 on the body 12 is effected by a translational movement parallel to the vertical axis Oz. The mounting of this variant is illustrated in FIG. 9. In the two variants, the mounting principle is however the same: the tabs 42 of the guide member 40 are inserted into the cavities 50, and the pins 84 of the side panels 12b enter the keyholes 82 of the fixing device 80 passing through the channels 86 to be received in the circular clearances 87.
    Arranged in this way, the head 11 covers an end band 98 of the end portion 9. More particularly, the rear edge 89 of the head 11 is in contact with the end band 98. This contact 94, illustrated in FIG. 2, blocks the rotation of the adapter 2 relative to the end portion 9. Da additionally, the head 11 presses the button 17 against a slice of the first wall 95 and participates in blocking any rotation of the adapter 2 relative at the terminal 9.
    Disassembly of the wiping system 4 is done in reverse order. In particular, the head 11 is separated from the body 12 by a translation in the opposite direction to that which has enabled it to be positioned on the body 12. The body 12 of the adapter 2 is then removed from the end part 9 of the drive arm 3.
    In normal and usual use of the wiping system comprising a drive arm 3, a wiper blade 2 and a connection device 8, the movement of the drive arm 3 results in a centrifugal force acting on the adapter 2 and the wiper blade 1. This centrifugal force mainly results in a translational movement of the adapter 2 in a direction parallel to the axis Ox, in an opposite direction to the drive arm 3.
    The button 17 of the adapter 2 collaborates with the orifice 90 of the terminal part 9 of the drive arm 3, to secure the adapter 2 and the drive arm 3 despite the effect of the above-mentioned centrifugal force. The lateral faces 21 of the button 17 abut on the lateral faces of the orifice 90.
    The foregoing description clearly explains how the invention makes it possible to achieve the objectives which it has set itself and in particular to propose a two-piece adapter allowing simple mounting on drive arms capable of being of various conformation, and particularly on a drive arm comprising a terminal part comprising oblong openings formed in the second walls of the terminal part and open on the front edge of the latter.
    Of course, various modifications can be made by those skilled in the art to the adapter which has just been described by way of nonlimiting example, provided that at least one adapter is used comprising a head and a body arranged in relation to each other by means of a guide member and a fixing device.
    In any event, the invention cannot be limited to the embodiment specifically described in this document, and extends in particular to all equivalent means and to any technically operative combination of these means.
