    ADAPTER FOR CONNECTING A WIPER BROOM TO A
    VEHICLE WIPING SYSTEM DRIVE ARM
    AUTOMOTIVE
    The invention relates to the field of wiping and / or cleaning the glass surfaces of a motor vehicle, and it relates more particularly to a connection device between a wiper blade and a drive arm of that. -this.
    Motor vehicle windshield wipers are designed to remove, by sweeping, liquids and dirt that can disturb the driver's vision of his environment. These wipers generally comprise at least one drive arm which performs an angular reciprocating movement against the glazed surface considered, and at least one wiper blade equipped with a scraper blade made of an elastic material. By rubbing against a glass surface, this blade sweeps away water and a certain number of dirt, and evacuates them outside the driver's field of vision.
    Whatever the configuration of the wiper blade: articulated stirrups that hold the scraper blade in several distinct zones, or a metal blade that holds the scraper blade over its entire length, it is attached to the drive arm of the system wiping by a connection device which generally comprises at least one connector and one adapter. The connector is secured to the wiper blade, and the adapter is a part which is configured, on the one hand, to cooperate with the connector and, on the other hand, to be engaged with a terminal part, or yoke, of the drive arm. Connector and adapter cooperate to achieve the attachment of the brush on the drive arm and the articulated connection between these two sets.
    In the market for the sale of parts and accessories for the aftermarket of motor vehicles, it is known to offer the same brush, sold equipped with its own connector, adaptable for several types of drive arm. It is therefore advisable to design an adapter which can be used with the greatest possible number of types of arm yokes and with the greatest possible number of types of brush connectors, since it is the adapter which forms the interface between these two elements. . In this context, the ergonomics to assemble or separate the wiper blade from the drive arm is an essential characteristic, and it is necessary to implement a solution that is simple to use, but nevertheless reliable and durable.
    The present invention aims to provide a solution for making the connection of a wiper blade to a particular type of yoke of the drive arm for a wiping system of a motor vehicle. The particular type of drive arm yoke with which the adapter according to the invention is more particularly intended to cooperate has, perpendicular to its longitudinal direction of extension, a cross section in the shape of an inverted U, the vertical branches of which are formed by two side walls of this yoke and the transverse branch of which is formed by an upper wall of said yoke, said upper wall comprising at least one through orifice. Upper wall and side walls of this screed thus delimit between them a reception volume. The particular yoke to which the invention applies more precisely also comprises two vents each arranged longitudinally on one of its side walls from a free front end edge of this side wall.
    To achieve the goal it has set itself, the invention provides an adapter intended to connect a wiper blade to a drive arm of a wiping system for a motor vehicle, the adapter comprising a head and a body which extends in the extension of one another in a longitudinal direction of the adapter, the adapter comprising a means of connection in rotation with a connector secured to the wiper blade, the head and the body of the adapter each being formed at least of an upper wall from which at least two lateral flanks originate so as to delimit an internal volume in which the connector is able to extend, the body of the adapter comprising at least hooking means for hooking the adapter with a yoke of the drive arm, characterized in that the head of the adapter comprises a second hooking means delimiting at least one housing capable of accommodating both a oi upper of the yoke of the drive arm, in particular its free end, and a rib of the body of the adapter.
    By convention, throughout this document, the longitudinal qualifier applies to the direction in which the head and the body of the adapter according to the invention extend in extension of one another, the transverse qualifier applies to a direction substantially perpendicular to the longitudinal direction and joining together the lateral flanks of the adapter according to the invention, and the vertical qualifier designates the direction perpendicular to both the longitudinal direction and the transverse direction.
    In a wiping system comprising a wiping brush equipped with its connector and assembled, by means of an adapter according to the invention, with a yoke of a drive arm of said wiping system, the lower qualifiers or bottom indicate more precisely the regions close to the surface to be wiped in the vertical direction, and the qualifiers superior or high designate the regions which move away from the latter in this same vertical direction.
    With reference to these different directions, the head and body of the adapter according to the invention thus each have, in a vertical transverse plane, a section whose shape is substantially that of an inverted U formed from their upper wall from which extend, perpendicular or substantially perpendicular, the two lateral sides, vertical or substantially vertical, of this head and / or of this body. Upper wall and lateral sides of the head and the body of the adapter according to the invention together define an internal volume thereof.
    Advantageously, the receiving housing of the second attachment means is delimited, on the one hand, by a tooth capable of coming to bear on an upper wall of the yoke of the drive arm, outside the internal volume of the adapter, and, on the other hand, by a hook able to cooperate with the rib arranged in the body of the adapter. According to another characteristic of the invention, the tooth extends in the longitudinal extension of the upper wall of the head, in the direction of the body of the adapter, beyond an edge formed at the interface between head and body.
    According to another characteristic of the invention, the hook is formed by a foot which extends, within the internal volume of the adapter, in particular from the upper wall of the head of this adapter, opposite of the latter in the vertical direction previously defined. An appendage extends, for example in a longitudinal direction substantially parallel to that of the aforementioned tooth, from the free end of the hook foot. This appendage advantageously comprises, at its free end in the longitudinal direction of extension of the head of the adapter according to the invention, a bead responsible for hanging the hook on the rib.
    According to another characteristic of the invention, the rib extends within the internal volume in a direction transverse to the body, perpendicular to a longitudinal axis of extension of this body. The rib is for example arranged in the body of the adapter and extends substantially transversely within the internal volume of this body. According to one embodiment of the invention, this rib is in contact with the lateral flanks of the body of the adapter, and thus constitutes a means of reinforcing the latter. Such a rib is advantageously molded simultaneously with the lateral flanks of the body.
    According to another of its characteristics, the adapter according to the invention comprises means for tilting in rotation of its head relative to its body about a substantially transverse axis, such a transverse axis being for example located in the vicinity of the interface between head and body. According to a particular embodiment of the invention, the head is removable relative to the body.
    Alternatively, the head and the body are two separate and separable parts, these two parts nevertheless being made integral with one another by the second attachment means.
    Throughout this document, the position of the adapter according to the invention will be designated by the closed position, in which the head and the body thereof extend in the longitudinal extension of each other, and by position open any position of the adapter according to the invention in which the head of the latter is tilted in rotation relative to its body thanks to the aforementioned tilting rotation means, or separated from the body.
    In the open position of the adapter, the second attachment means is moved away from the body of the adapter both in the longitudinal direction and in the vertical direction, but due to the direction of the axis around which it rocks by relative to the body, the adapter head remains aligned with its body in the transverse direction.
    According to the invention, the means for tilting the head of the adapter in rotation relative to its body comprise at least one articulation strap, in particular two articulation straps, each arranged between a lateral blank of the head and a lateral flank of the body. Each strap forms a hinge that connects the head and body of the adapter.
    According to different characteristics of the invention, which can be taken alone or in combination:
    the body comprises at least two crosspieces which extend, within the internal volume, in the direction of the head, in the longitudinal extension of the lateral flanks of the body;
    the first attachment means comprises a stud delimited by a distal wall and by side walls which extend substantially perpendicular to the distal wall;
    the stud protrudes from an upper wall of the body, outside the internal volume;
    the stud comprises at least one projection which extends, in the longitudinal direction, beyond at least one of the side walls delimiting the stud; the advance extends longitudinally in the direction of the head;
    the first attachment means and the second attachment means are formed longitudinally on either side of the rotating connection means;
    - A light is arranged in the upper wall of the body so that it extends, in the longitudinal direction, beyond the first attachment means in the direction of the head of the adapter;
    - A means for the rotational connection of the adapter with a connector of a wiping system is arranged in the region of the body of this adapter; first attachment means and second attachment means are formed longitudinally on either side of the rotating connection means;
    the rotationally connecting means of the adapter with the connector is for example a single strand arranged from an inner face of at least one of the lateral flanks of the body and extending towards the inside of the internal volume. Alternatively or additionally, the means of rotationally connecting the adapter with the connector is an orifice formed in at least one of the lateral flanks of the body of the adapter. According to an alternative embodiment, the rotational connection means consists of at least two openings, cylindrical of circular or square section, arranged in each lateral flank of the body of the adapter. These openings cooperate with a connector associated with a wiper blade when connecting such a brush with the adapter according to the invention. More specifically, these openings are intended to be each engaged on a strand made of material with the connector, or on a shaft attached to the connector;
    according to yet another alternative embodiment, the rotational connection means comprises on one side a single strand formed in one of the lateral flanks of the body and a single opening formed in the other lateral flank of the body.
    If the transverse dimension of the head or body of the adapter according to the invention is defined as the distance, along a plane substantially parallel to the plane of the upper wall of this head or this body, measured between surfaces of these lateral flanks located outside the internal volume of the adapter, the transverse dimension of the head of the adapter according to the invention is greater than the transverse dimension of the body of the adapter according to the invention. Similarly, if we define the height of the head or body of the adapter according to the invention as the dimension, measured along a plane substantially parallel to that of the lateral flanks of this head or this body, between the surface from the upper wall situated outside the internal volume of the adapter and the lower edge of the lateral flanks, the height of the head of the adapter according to the invention is greater than the height of its body. In other words, the head is higher and / or wider than the body of the adapter of the invention.
    The invention also covers a connection device comprising an adapter as described in this document and a connector able to be secured to a wiper blade, characterized in that the adapter and the connector are connected by the connecting means in rotation.
    The invention finally covers a wiping system, in particular for a motor vehicle, comprising a wiping brush, a drive arm and an adapter as described in this document or a connection device as mentioned above, in which the the adapter is housed in a yoke of the drive arm, in which the first attachment means and the second attachment means are arranged relative to the upper wall of the body so as to enclose both an upper wall of the clevis and rib previously defined.
    Advantageously, the dimensions respectively of the head and of the body of the adapter are defined such that an edge formed at the interface between said head and said body is capable of coming into abutment edge to edge against the thickness , respectively, of the upper wall and / or the side walls of the yoke. A continuous outer surface is thus formed once the adapter is assembled with the drive arm.
    In such a wiping system, the first attachment means extends into an orifice arranged in the upper wall of the yoke.
    Once the adapter according to the invention assembled with a wiper blade connector, the positioning of the adapter according to the invention on the yoke of a drive arm of the type described above is carried out from the next way.
    Advantageously, the adapter is first of all placed in an open position, in which its head is tilted in rotation relative to its body thanks to the tilting means defined above. Alternatively, the head is separated from the body.
    The adapter body is then engaged with the yoke of the drive arm, so that the stud of the first attachment means is inserted into the through hole formed in the upper wall of this yoke.
    A rotation movement of the body of the adapter is then carried out around a transverse axis of the adapter, to bring the upper wall of this body in the vicinity of the upper wall of the yoke of the drive arm.
    The head is then tilted in rotation relative to the body until the adapter is in its closed position. During this rotational tilting movement of the head of the adapter with respect to its body, the hook then locks the head of the adapter with the body of the latter. Alternatively, the head can be attached to the body until the hook locks the head of the adapter relative to its body.
    When the adapter according to the invention is hooked into the yoke, the upper wall of the body of this adapter is located, within the receiving volume of this yoke, pressing against the upper wall of the latter, and the lateral flanks of the same body are advantageously resting, within this same reception volume, against the side walls of the yoke. Thus, the upper wall of this yoke is sandwiched between, on the one hand, the upper wall of the body of the adapter according to the invention and, on the other hand, both the tooth carried by the first attachment means and the second attachment means.
    To separate the adapter according to the invention from the yoke of the drive arm, it suffices to tilt the head of the adapter in rotation relative to the body thereof or, in other words, to place the adapter in an open position. It is therefore advisable to unlock the hook of the second attachment means with the transverse rib arranged in the body of the adapter by exerting vertical pressure on the tooth of this second attachment means and then to disengage the adapter. 'with the yoke of the drive arm.
    Other characteristics and advantages of the present invention will appear more clearly with the aid of the following description and the drawings among which:

    FIG. 1 illustrates a wiping system for a motor vehicle. This system comprises a drive arm 5 which performs an angular back-and-forth movement against a surface to be wiped, and a wiping brush 7, itself constituted for example by one or more vertebrae 70 carrying a scraper blade 71 made of an elastic material. In the angular reciprocating movement of the drive arm 5, the wiper blade 7 and its scraper blade 71 are driven in an angular movement against the glass surface to perform the desired wiping / cleaning operation.
    The wiper blade 7 is attached to the drive arm 5 by a connection device which comprises a connector 8 and an adapter 100. The connector 8 is secured to the wiper blade 7, and the adapter 100 provides an interface between this connector 8 and an end portion of the drive arm 5, otherwise known as a yoke 500. Connector 8 and adapter 100 cooperate to achieve the attachment of the brush 7 on the drive arm 5 and an articulated connection between these two elements.
    The invention relates to a particular type of adapter 100 intended to cooperate with a particular type of yoke 500 of the drive arm, in particular for the purpose of providing replacement wiper blades to be mounted on a drive arm. having this particular type of screed 500.
    ίο
    The yoke 500, shown schematically in side view in Figure 6, with which the adapter 100 according to the invention is intended to cooperate, has an upper wall 50 from which extend, perpendicular or substantially perpendicular to the wall upper 50, two side walls 51. The yoke 500 thus has a cross section whose shape is substantially that of an inverted U and whose base is formed by the upper wall 50 and where the branches are formed by the side walls 51. Upper wall 50 and side walls 51 of this yoke 500 together define a reception volume 54, visible in FIG. 6.
    The yoke 500 also comprises, arranged in its upper wall 50, an orifice 52, passing through, and each of its lateral walls 51 comprises, arranged from its free front edge 510, a hole 53 which extends substantially longitudinally towards the rear of the drive arm 5, substantially parallel to the upper wall of the yoke 500. Such gills 53 have an oblong shape and these gills open on a free front end edge 510 of the yoke 500.
    With reference to FIGS. 2 to 7, the adapter 100 according to the invention comprises a head 1 and a body 2, the head 1 extending, in the directions previously defined, towards the front of the adapter 100 according to the invention, and the body 2 extending, in the directions defined above, towards the rear of this same adapter 100. According to one embodiment of the invention, the adapter 100 is produced by injecting a polymeric material into a mold, and body 2 and head 1 are made of material in a single block. Advantageously, the material chosen has mechanical properties which confer a certain flexibility on the adapter 100. This is a first embodiment of the adapter where the head 1, although removable with respect to the body 2, is connected to it.
    The invention relates to a second embodiment where the head 1 is a separate piece separate from the body 2, the head 1 being nevertheless attached to the body 2 by a second attachment means 4 which comprises at least one housing 400 capable of accommodating both a free end of an upper wall 50 of the yoke 500 and a rib 9 arranged in the body 2. The second attachment means 4, in addition to participating in the fixing of the adapter 100 in the yoke 500 , also ensures a joining of the head 1 on the body 2. The description below relates more particularly to the first embodiment, but it is understood that this description is applicable to the adapter according to the second embodiment.
    As shown in Figures 2 and 3, the body 2 is formed of an upper wall 20 and two substantially vertical lateral sides 21a, 21b, which each extend from a longitudinal side of the upper wall 20, substantially perpendicular to the upper wall 20, downwards in the previously defined vertical orientation. According to the embodiment illustrated by the figures, the longitudinal dimension of the body 2 is greater than the transverse dimension of the latter.
    The head 1 is formed by an upper wall 10 and two lateral sides 11a, 11b which are substantially vertical and each extending from a longitudinal side of the upper wall 10, downwards in the vertical orientation defined above. . According to the embodiment illustrated by the figures, the upper wall 10 of the head 1 is extended, opposite the body 2, until it joins edges 110a, 110b, lateral flanks 11a, 11b opposite the edges of these flanks by which these are attached to the upper wall 10 of the head 1.
    Head 1 and body 2 therefore each have a cross section in the form of an inverted U, the transverse branch of which consists of the upper walls, respectively 10 and 20, and the vertical branches of which are formed by the lateral flanks, respectively 11a, 11b and 21a, 21b, of these two parts of the adapter 100 according to the invention.
    The upper walls, respectively referenced 10 and 20, of the head 1 and of the body 2 of the adapter 100 according to the invention, as well as the lateral flanks, respectively referenced 11a, 1 lb and 21a, 21b, delimit an internal volume 101 of this adapter. Such a volume is intended to receive all or part of the connector 8 carrying the wiper blade 7, and the mechanical connection between the adapter 100 and the connector 8 is effected in the internal volume 101 of the adapter, using a rotating connection means 6.
    According to an advantageous characteristic of an embodiment of the invention, a transverse dimension, that is to say the dimension along the axis Oy previously defined, of the head 1 is greater than that of the body 2, measured according to the same direction. In other words, the head 1 comprises an edge 14 substantially parallel to the vertical transverse plane (Oyz) of the orthonormal coordinate system previously defined.
    Likewise, a vertical dimension, that is to say the dimension along the axis Oz previously defined, of the head 1 is greater than that of the body 2, measured along the same axis.
    In other words, the head 1, whether separate or attached to the body 2, projects above and to the sides of this body 2. In other words, the head 1 is higher and wider than the body 2. The edge 14 of the head 1 facing the body 2 thus extends to the entire periphery of the interface between head 1 and body 2 of the adapter according to the invention.
    According to an advantageous embodiment of the invention, the vertical and transverse dimensions of this edge 14 of head 1 are substantially equal respectively to the thickness of the upper wall 50 of the yoke 500 and / or to the thickness of the side walls 51 of this same yoke 500 with which the adapter 100 according to the invention is intended to cooperate, so that the free front edge 510 of this yoke 500 can come to bear against this edge 14 of head 1. Such characteristics allow to obtain a head 1 which is flush with the external faces of the yoke 500.
    According to one aspect of the invention visible in Figure 3 in particular, a lumen 22 is arranged longitudinally in the upper wall 20 of the body 2 of the adapter 100. Advantageously, the transverse dimension, or width, of the lumen 22 is substantially equal to the transverse dimension of the internal volume 101 or, in other words, to the distance, measured transversely, between internal surfaces 210a, 210b of the lateral flanks 21a, 21b of the body 2, which delimit this internal volume 101.
    The adapter 100 according to the invention comprises an attachment means 3, hereinafter referred to as the first attachment means. The adapter 100 also comprises a second attachment means 4, distinct from the first attachment means 3. Advantageously, the first attachment means 3 is arranged on the body 2 and the second attachment means 4 is arranged on the head 1 of the adapter 100 according to the invention.
    Advantageously and as visible in Figures 2, 3, 6 and 7, the first attachment means 3 consists for example of a stud 33 formed by a distal wall 30 from which extends a plurality of side walls 31. According to the non-exclusive embodiment of the invention, more particularly illustrated by the figures, the stud 33 is substantially parallelepipedal, and therefore it comprises, extending from its distal wall 30 and substantially perpendicular to it- ci, four side walls 31. Whatever shape retained for the pad 33, the dimensions thereof are, according to the invention, defined to be complementary to those of the orifice 52 arranged in the upper wall 50 of the yoke 500 with which the adapter 100 is intended to cooperate, in order to allow easy insertion but without excessive play of this stud 33 into this orifice 52.
    According to the invention, the distal wall 30 of the stud 33 forming the first attachment means 3 extends, in the longitudinal direction Ox defined above, outside the internal volume 101 previously defined. According to a characteristic of the invention, the pad 33 comprises an projection 32 arranged to extend above the upper wall 20 of the body 2. Such an projection 32 is formed in the extension of the distal wall 30 of the pad 33, and this projection 32 forms a protrusion which extends beyond one of the side walls 31 of this same pad 33, here the front side wall referenced 31a.
    More precisely, this projection 32 extends, in the longitudinal direction previously defined, in the direction of the head 1 of the adapter 100. In other words, with reference to the orientations defined above, the projection 32 extends towards the front of the adapter 100, beyond the front side wall 3a of the stud 33 and overhanging the upper wall 20 of the body 2.
    The second attachment means 4, visible in FIGS. 2 to 7, comprises for example a tooth 40 and a hook 41. According to the invention, this second attachment means 4 is arranged on the head 1 of the adapter 100 As shown in the figures, the tooth 40 extends, from the edge 14 of the head 1 of the adapter 100, in the longitudinal extension of the upper wall 10 of the head 1 in the direction of the body 2. At d '' In other words, and with reference to the directions and orientations defined above, the tooth 40 extends towards the rear of the adapter 100, beyond the edge 14 and overhanging the through light 22 when the adapter 100 is in its closed position, as illustrated in FIGS. 1, 2, 5 and 7.
    The hook 41 extends within the part of the internal volume 101 of the adapter 100 delimited by the upper wall 10 and by the lateral flanks 11a, 11b, of the head 1 of the adapter 100. More precisely, the hook 41 is formed of a substantially vertical foot 410 from which extends a substantially longitudinal appendage 411. According to the embodiment illustrated in the figures, the hook 41 extends substantially centered in the transverse direction Oy, as does the tooth 40.
    The foot 410 extends, in a substantially vertical direction, from an internal face of the upper wall 10 situated opposite the internal volume 101, in the direction of this internal volume 101. In other words, with reference to the previously defined orientations the foot 410 extends, within the internal volume 101, substantially vertically downwards. As shown more particularly in FIGS. 3 and 7, the dimension, in the vertical direction Oz, of the stand 410 is less than the dimension, in this same vertical direction, of the internal volume 101. According to the embodiment more particularly illustrated by the Figures, the foot 410 is attached to the upper wall 10 in a region located, in the longitudinal direction Ox, towards the rear of the head 1, in the immediate vicinity of the edge 14 of head 1. In other words, according to the longitudinal direction Ox of extension of the adapter 100 in its closed position, the tooth 40 is located between the body 2 and the foot 410. This is also the case of the edge 14 of the head 1.
    The appendix 411 extends, from the free end of the foot 410, in a longitudinal direction substantially parallel to the longitudinal direction Ox, in the direction of the body 2 of the adapter 100. In other words, the appendix 411 and tooth 40 are substantially parallel to each other. According to a characteristic of the invention, and as shown more particularly in FIG. 7, appendix 411 forms, at its free end, a bead 412. The tooth 40 and the hook 41 thus delimit, between them, a housing 400, designated in the following accommodation 400 accommodation.
    The second attachment means 4 of the adapter 100 also includes a rib 9 arranged on or in the body 2 of this adapter 100, and more particularly visible in FIGS. 3, 4 and 7. Such a rib 9 serves as a counterpart on which hooks the hook 41. The rib 9 extends in a direction substantially parallel to the transverse direction Oy. Such a rib 9 extends at least in part in the extension of the upper wall 20 of the body 2. According to the embodiment illustrated by the figures and with reference to the orientations defined above, the rib 9 extends, in a vertical or substantially vertical direction, downwards.
    According to this embodiment, the rib 9 also extends between the interior walls of the lateral flanks 21a, 21b of the body 2 of the adapter 100, bearing on these interior walls. As defined and described here, the rib 9 therefore also forms, according to the embodiment illustrated in the figures, a transverse reinforcement of the body 2 of the adapter 100 according to the invention.
    Advantageously, the dimension, in the vertical direction Oz, of the rib 9 is less than that of the foot 410 of the hook 41 measured in this same vertical direction. On the other hand, the dimension of the rib 9, in this vertical direction Oz, is less than that of the foot 410 of the hook 41 less the measurement of the bead 412, measured in this same vertical direction.
    According to a first embodiment illustrated in Figures 3 to 5, the invention provides tilting means 200 for rotation of the head 1 of the adapter 100 relative to its body 2, about an axis Y2 substantially parallel to the transverse direction Oy.
    Figures 4 and 5 show close-up views of the head 1 and the front end of the body 2, in section along a vertical longitudinal plane substantially parallel to the Oxz plane of the orthonormal reference frame previously defined. FIG. 4 shows a view of the adapter 100 in an open position, in which the head 1 is tilted in rotation relative to the body 2 around the axis Y2, and FIG. 5 shows a detailed close-up view of the tilting means 200, in the closed position of the adapter 100, in which head 1 and body 2 extend in the longitudinal extension of one another. FIG. 4 shows the lateral flank 21b of the body 2, from which extends a strand 61 which forms an exemplary embodiment of the rotating connection means 6. FIG. 4 also illustrates in section the upper wall 10 of the head 1, tooth 40 and hook 41 of the second attachment means 4.
    An articulation strap 201b arranged within the internal volume 101 forms an example of the tilting means 200. This articulation strap 201b emerges in particular from an interior wall 111b of a lateral flank of the head 1, starting from a first base 203. It will be noted that the invention extends to the case where two articulation straps are provided, each emerging from a lateral flank of the head 1 of the adapter 100.
    Each articulation strap 201b extends, from the wall on which it is arranged, towards the interior of the internal volume 101. To allow the articulation sought during the tilting in rotation of the head 1 relative to the body 2 , each articulation strap 201b extends over a transverse dimension close to, but less than, the transverse dimension of a complementary clearance, respectively 211a, 211b, arranged inside the internal volume 101. Such a clearance is extends along the lateral flanks 21a, 21b of the body 2. Each articulation strap 201b, is also attached to the body 2 at the level of the head edge 14 1. This connection takes place by means of a second base 202a, 202b from the lateral flank 21a, 21b of the body 2.
    Each articulation strap therefore includes a first base from a side blank of the head, a second base from a side blank of the body 2 and a flexible loop 204 which extends between the first base and the second base.
    According to the embodiment illustrated for example by FIGS. 3 and 4, the clearances 211a, 211b are delimited in particular by two crosspieces, respectively 212a, 212b, which extend longitudinally, within the internal volume 101 and in the direction of the head 1, the lateral flanks 21a, 21b, of the body 2. Each of the crosspieces 212a, 212b has a thickness, in the transverse direction Oy, less than that of the lateral flank 21a, 21b, in the longitudinal extension of which it extends. In addition, each cross member 212a, 212b, is arranged such that its inner wall is located in the longitudinal extension of the inner wall 210a, 210b of the corresponding lateral flank. Each clearance 211a, 211b, is thus delimited by a crosspiece 212a, 212b, by a second base 202a, 202b, by a first base 203 and by the inner wall 111b of the lateral flanks of the head 1, when the adapter 100 is in its closed position.
    The articulation of the head 1 relative to the body 2 thanks to the tilting means 200 is made by rotation of the head 1 around the transverse axis Y2 which passes through the head 1 in the vicinity of the lower edges 110a, 110b, of each of the lateral flanks 10a, 10b of this head. The transverse axis Y2, substantially parallel to the transverse direction Oy of the adapter 100, is advantageously located outside the internal volume 101 to allow an angular tilting as wide as possible of the head 1 relative to the body 2. For to do this, the loop 204 constituting the articulation strap emerges outside the internal volume 101.
    When the head 1 is pivoted in rotation about the transverse axis Y2 relative to the body 2, it moves in a substantially longitudinal vertical plane, downwards with reference to the orientations defined above. More precisely, in this rotational tilting, the tooth 40 and the hook 41 move away from the body 2 of the adapter 100 in the longitudinal and vertical directions.
    For its association with a wiper blade connector 8, the adapter 100 according to the invention comprises at least one connecting means 6 in rotation. According to the embodiment of the invention illustrated by the figures, this rotational connection means comprises, arranged from the internal surface 210b delimiting the internal volume 101, a single substantially cylindrical strand 61, centered on a transverse axis of rotation Yl of the adapter 100 relative to the connector 8. According to the embodiment illustrated in FIG. 6, the strand 61 is carried by the lateral flank 21b of the body of the adapter 100.
    It goes without saying that any equivalent means can be implemented for the production of the connecting means 6 in rotation of the adapter 100 with its connector 8 without harming the invention: thus, it is possible, not exhaustively, that two substantially cylindrical strands, centered on the transverse axis of rotation Yl, are arranged face to face within the internal volume 101 of the adapter, to cooperate with a hole 80 of complementary shape and arranged on the connector as visible on Figure 7. It is also possible that this rotational connection is achieved by cooperation of strands arranged on the connector with one or more holes formed in the lateral flanks of the adapter according to the invention and centered on the same transverse axis Yl. Alternatively, it is conceivable that the connector and adapter are provided with coaxial holes in which a shaft is housed, in particular a metal shaft.
    Advantageously, the transverse axis of rotation Yl crosses the body 2 of the adapter 100 according to the invention, near the edge 14 delimiting the head 1 near the body 2. Advantageously, the diameter of the substantially cylindrical strand 61 is defined to allow its engagement in the complementary hole 80, visible in FIG. 7, arranged on the connector 8. It should therefore be noted here that the rotating connection means 6 is substantially located, in the longitudinal direction of the adapter 100 according to the invention, between the first attachment means 3 and the second attachment means 4 and, more particularly, between the first attachment means 3 and the tilting means 200 in rotation.
    Figures 6 and 7 illustrate the assembly of the adapter 100 according to the invention with the yoke 500 of the type described above. In these figures, the adapter 100 is shown previously assembled with a connector 8 secured to a wiper blade. According to the embodiment more particularly described here and illustrated by FIGS. 6 and 7, the assembly of the adapter 100 according to the invention with the connector 8 secured to the wiper blade is done by engagement of a substantially cylindrical strand 61 carried by the adapter 100 in the hole 80 arranged in the connector 8. Thus assembled, the adapter 100 and the connector 8 form a connection device for securing a wiper blade 7 to a drive arm 5.
    It should be noted that once thus preassembled, the connector 8 and the adapter 100 have relative to each other a freedom in rotation about the transverse axis Y1 of the connecting means 6 in rotation.
    The assembly of the adapter 100 with a yoke 500 of the drive arm 5 as illustrated in FIG. 6 is done, firstly, by engagement of the first hooking means 3 with the upper wall 50 of the yoke 500. To achieve this engagement, the adapter 100 is inclined relative to the yoke 500, then engaged within the receiving volume 54 thereof, so that the pad 33 forming its first attachment means 3 can be inserted into the orifice 52 of this yoke 500.
    Once the stud 33 and its projection 32 inserted into the orifice 52, the assembly of the adapter 100 with the yoke 500 continues with a rotational movement of the assembly of the adapter 100 around a transverse axis parallel to the aforementioned axis Y1 and passing through a point of contact between pad 33 and an edge of the orifice 52. This rotational movement is illustrated by the arrow Fl in FIG. 6. The result is to bring the wall upper 20 of the body 2 against the upper wall 20 of the yoke 500.
    The adapter 100 is previously placed in an open position, by tilting in rotation of the head 1 relative to the body 2 around the axis Y2, in the direction illustrated by the arrow F2 in Figure 6, as regards the first embodiment. As regards the second embodiment, the adapter 100 is previously placed in an open position by separation of the head 1 from the body 2.
    Once the upper wall 20 of the body 2 against the upper wall 50 of the yoke, the head 1 is attached to the body 2, or tilted towards the body 2 as illustrated by the arrow F3, depending on the embodiment of the invention. The dimensions and respective configurations of the hook 41 and of the rib 9 are defined, according to the invention, in such a way that the rib 9 engages in the space between the foot 410 of the hook, its appendage 411 and its bead 412 In other words, the rib 9 then engages in the reception housing 400 defined above and delimited by the tooth 40 and the hook 41 of the second attachment means 4. In other words, the rib 9 is hooked by the hook 41 within the reception housing 400. It will be noted that the rib 9 is pressed against the hook 41 and against the upper wall 50 of the yoke 500, the latter being also in abutment against the tooth 40.
    The rotational movement continues until the edge 14 of the head 1 is brought into contact with the free terminal front edge 510 of the yoke 500. The tooth 40 of the second attachment means 4 is then located, with reference to the orientations above. defined, engaged above the upper wall 50 of the yoke 500, outside the reception volume 54 delimited by the latter. In other words, with reference to the orientations defined above, the upper wall 50 of the yoke 500 is then engaged in the reception housing 400, with the rib 9.
    In these tilting movements in rotation about the substantially transverse axis Y2, the articulation straps 201a, 201b flex around the axis Y2. Advantageously, the dimensions of these various elements are defined in such a way that the crosspieces 212a, 212b, and the internal walls of the lateral flanks 10a, 10b of the head 1, provide transverse guidance of the head 1 relative to the body 2.
    It follows from the above, and as shown more particularly in FIG. 7 that, in this position, the upper wall 50 of the yoke 500 is received in the reception housing 400, above the rib 9. It it is pinched and blocked in the vertical direction Oz, on the one hand, by the tooth 40 and, on the other hand, by the rib 9, itself blocked, in this same vertical direction, by the appendage 41L Furthermore , in this position, the rib 9 is blocked in the hook 41, in the longitudinal direction Ox, by the presence of the bead 412 which then constitutes, by the concomitant engagement of the upper wall 50 of the yoke 500 in the housing reception 400, a means of locking the adapter 100 with the yoke 500.
    Rib 9 and upper wall 50 of the yoke 500 are thus enclosed, that is to say sandwiched, in the vertical direction Oz, between, on the one hand, the appendix 411 of the hook 41 and the tooth 40.
    The insertion of the projection 32 in the through hole 52, then the complete insertion of the stud 33 in this hole 52 operates a complementary attachment of the adapter 100 in the yoke 500 and a complementary locking of this assembly in the direction longitudinal Ox.
    When the adapter 100 is housed in and hooked to the yoke 500, the upper wall 20 of the body 2 is, within the receiving volume 54 of this yoke, resting against the upper wall 50 of the latter, and the lateral sides 21a, 21b of this same body 2 are advantageously in abutment, within this same reception volume 54, against the side walls 51 of the yoke 500. Thus, the upper wall 50 of this yoke 500 is also enclosed between, on the one hand, the upper wall 20 of the body 2 of the adapter 100 and, on the other hand, the projection 32 of the first attachment means 3.
    It should also be noted that once the adapter 100 according to the invention has been assembled with the yoke 500 of the drive arm 5, the upper walls, respectively 50 and 10, of this yoke 500 and of the head 1 of this adapter , as well as the lateral walls 51 of this yoke and the lateral flanks 11 of the head 1 of this adapter advantageously form a continuous surface, thus contributing to the aesthetics of the assembly, and also eliminating any zone of possible accumulation of debris , dirt or particles potentially harmful to the proper functioning of the assembly.
    To separate the adapter 100 from the yoke 500, it suffices to tilt the head 1 relative to the body 2 in rotation about the substantially transverse axis Y2, in the direction illustrated by the arrow F2 in Figure 6. En d ' in other words, it suffices to bring the adapter 100 into an open position. This tilting of the head 1 releases the tooth 40 from the upper wall 50 of the yoke 500. This movement is made possible by the elasticity of the hook 41 and, more particularly, of its foot 410, elasticity which results from its shape and the nature of the material which constitutes the adapter 100. By continuing this opening movement of the adapter 100, it becomes possible to tilt the body 2 of the adapter 100 in order to disengage it completely from the yoke 500, in an opposite direction to that illustrated by the arrow Fl.
    The invention thus makes it possible to carry out a simple and effective attachment of an adapter 100 both with a drive arm 5 having a specific yoke of the type described above and with a connector 8 secured to a wiper blade 7, to form part of a wiping system for a motor vehicle.
    The invention cannot however be limited to the means and configurations described and illustrated, and it also applies to all means or equivalent configurations and to any combination of such means.
