    Adapter for a motor vehicle windscreen wiper and windscreen wiper comprising such an adapter
    TECHNICAL FIELD OF THE INVENTION
    The invention relates in particular to an adapter for a windscreen wiper, in particular for a motor vehicle.
    The invention also relates to an assembly comprising a wiper arm and an adapter according to the invention.
    The invention also relates to a wiper blade for a motor vehicle comprising a wiper blade and a connection assembly comprising an adapter according to the invention.
    TECHNICAL BACKGROUND OF THE INVENTION
    A motor vehicle is conventionally fitted with windscreen wipers, in particular for washing the external surface of the windshield and thus preventing the driver's vision of his environment from being disturbed.
    A wiper generally comprises a drive arm, performing a reciprocating movement, in particular angular, and a wiper blade elongated longitudinally which carries a wiper blade or scraper blade made of a material elastic such as rubber or an elastomeric material.
    The wiper blade rubs against the outer surface of the windshield and wicks water away from the driver's field of vision.
    In a classic version, the wiper blade is made in the form of articulated stirrups which hold the wiping scraper blade in several discrete places distributed longitudinally by giving it a bending allowing it to match the possible curvature or curve of the windshield.
    In a more recent version called fiat blade (for flat blade), the wiper blade is made in the form of a semi-rigid assembly which holds the wiper blade over its entire length thanks to one or more vertebrae of bending allowing to apply the broom and the wiping blade on the windshield without having to use stirrups.
    In both designs, the wiper blade is connected to the drive arm by a connection system with a connector and an additional adapter.
    The connector is a part which is secured to the wiper blade and which is generally fixed directly to the wiper blade or to the fiat blade or flat blade, while the adapter is secured to the connector.
    The adapter is an intermediate piece that allows the connector to be fixed and attached to the drive arm. It is generally shaped to be engaged in a head or end piece in the form of a yoke and with an inverted U cross section of the drive arm.
    Each of these two components (connector and adapter) includes articulation means designed to cooperate with means complementary to the other component, to define at least one transverse axis of articulation of the two components relative to the another, which is also the axis of articulation of the wiper blade relative to the drive arm.
    According to a known technique, one of the components, such as the connector, generally comprises a substantially cylindrical physical axis which defines the axis of articulation and which is received in a housing of complementary shape to the other component.
    The adapter generally comprises an elongated body which is shaped to be engaged in the end piece of the free front end of the drive arm so that this body extends at least in part between two substantially parallel side walls of this piece terminal.
    An adapter allows you to associate a wiper blade with a particular type of end piece. In the case of the aforementioned end pieces with inverted U section, there are several varieties.
    A wiper arm is known, the end piece of which carries a cover mounted to slide in longitudinal translation. The cover is slidably mounted longitudinally between a first front position or advanced position, and a second rear position or retracted position. In addition to an aesthetic interest, this type of cover can perform other functions.

    DETAILED DESCRIPTION OF THE FIGURES
    In the following description, elements having an identical structure or analogous functions will be designated by the same references.
    In the following description, longitudinal, vertical and transverse orientations indicated by the trihedron L, V, T in the figures will be adopted without limitation. A horizontal plane is also defined which extends longitudinally and transversely.
    Thus, in the description, the longitudinal or lateral names refer to the orientation of the wiper blade or of the drive arm.
    The longitudinal direction corresponds to the main axis of the wiper blade or of the drive arm in which it extends from back to front according to the orientation of the axis L of the trihedron L, V, T.
    The internal, external, interior or exterior directions can refer to a room as a whole, and relate for example to the interior or exterior of this room.
    There is shown in Figure 1 a wiper 10 comprising in particular a wiper blade 12 and a drive arm 14 (also called wiper arm) of the wiper blade 1 2.
    The brush 12 is here of the fiat blade type and comprises a longitudinal body 16, a wiping blade 18, generally made of rubber or of elastomeric material, and at least one vertebra (not shown) which stiffens the blade and promotes its application on the outer surface of a vehicle window such as for example a curved windshield (not shown) of the vehicle.
    The longitudinal body 16 of the wiper blade 12 comprises an upper aerodynamic deflector 20 intended to improve the operation of the wiping system, this deflector having the function of improving the application of the wiper blade 12 on the windscreen breeze, and therefore improve the aerodynamic performance of the wiper 10.
    The wiper blade 12 further comprises end caps 22, or hooking clips, of the blade 18 and the vertebra on the longitudinal body 16, these tips 22 being located at each of the two opposite longitudinal ends. front and rear of the longitudinal body 16.
    The drive arm 14 is intended to be driven by a motor to follow a back and forth movement, and for example an angular alternating movement, allowing the wiping blade 18 to evacuate the water and possibly d other undesirable elements covering the exterior surface of the windshield.
    Substantially mid-length, the wiper blade 12 comprises a connection assembly comprising an intermediate connector 24 and an adapter 26, 1026.
    Two embodiments of an adapter 26, 1026, are shown. The first embodiment is shown in Figures 3 to 7. The second embodiment of the adapter is shown in Figures 10 to 22.
    Each adapter 26, 1026 is a part produced by molding in a single piece and it has a symmetry of design with respect to a median longitudinal and vertical plane.
    The adapter 26, 1026 secured to the arm 14 is mounted on the connector 24 so as to allow a degree of freedom in pivoting around a transverse axis of articulation Y which is substantially perpendicular to the longitudinal axis of the wiper blade - ice 1 2.
    This degree of freedom allows pivoting in both directions of the wiper blade 12 relative to the drive arm 14 and thus allows the wiper blade 12, during its movements, to follow the curvature or curve windshield.
    The adapter 26, 1026 ensures the connection of the wiper blade 12 to the drive arm 14 and in particular with a head or end piece of longitudinal front end of the drive arm 14 which can be formed in one piece with the drive arm, or be attached and fixed on it.
    In Figures 1 to 3 and 8, the end piece of the drive arm is a front free end section in the form of a yoke 28 with a cross section substantially in an inverted U shape.
    A cover 30 is slidably mounted on the free end yoke 28 and it covers the yoke 28.
    The yoke 28 has an elongated shape which extends along a longitudinal axis A which is generally substantially parallel to the general longitudinal axis of the wiper blade 12.
    The yoke 28 comprises a part 31 for connection to the rest of the drive arm 14, to which it is for example fixed by crimping.
    The part 31 has a generally elongated shape and extends along a longitudinal axis B substantially parallel to the axis A and offset laterally or transversely with respect to the axis A, as can be seen in FIGS. 1 and 2. The part 31 is connected to a rear end of the yoke 28.
    The yoke 28 comprises two vertical lateral walls of longitudinal orientation 32a, 32b, the upper longitudinal edges of which are connected together by an upper transverse wall of longitudinal orientation 34. The walls 32a, 32b and 34 delimit an interior housing space between them. of the adapter 26.
    The side walls 32a, 32b have a series of through notches 33a, 33b, 33c, 33d which are open vertically downwards and open into their lower longitudinal edges 37a, 37b.
    The notches 33a, 33b, 33c, 33d of each wall 32a, 32b are here four in number which are spaced from each other and arranged longitudinally one behind the other.
    The front notch 33a of each side wall 32a, 32b, located longitudinally furthest forward, has a relatively small longitudinal width compared to the other notches and it extends vertically substantially over the entire height of the corresponding side wall 32a , 32b.
    The rear notch 33d, located at the rear most longitudinally, has a relatively low height compared to that of the other notches.
    The notches 33b, 33c intermediate between the front notches 33a and rear 33d have a relatively large longitudinal width compared to that of the front notch 33a and they extend vertically substantially up to the height of the corresponding side wall 32a, 32b.
    The upper wall 34 has two through openings 38a, 38b arranged longitudinally one behind the other. The front opening 38a has a substantially circular outline and the rear opening 38b has a substantially rectangular outline.
    In section through a vertical and transverse plane, the cover 30 has a section substantially in the shape of an inverted U.
    The cover 30 comprises two longitudinal and vertical side walls 36a, 36b, the upper longitudinal edges of which are connected together by a longitudinal and horizontal upper wall 36c.
    The front vertical edges of the side walls 36a, 36b, and upper 36c are further interconnected by a front wall 36d of the hood of generally vertical and transverse orientation.
    In the mounted position of the cover 30, its upper wall 36c covers the upper wall 34 of the yoke 28 and its side walls 36a, 36b extend longitudinally on either side of the yoke, opposite the external faces of the side walls 32a , 32b (See Figure 2).
    The front wall 36d of the hood extends in front of the yoke 28 and it has a vertical slot 40 capable of receiving a portion facing the upper part of the deflector 20 of the wiper blade 12, visible in Figure 1.
    At its rear end, the upper wall 36c of the cover 30 has a notch 41 of generally C shape, which opens longitudinally into the free rear transverse edge of the upper wall 36c.
    The cover 30 is movable in longitudinal translation on the yoke 28 of the drive arm 14, between a rear position, shown in FIG. 2, and an advanced position offset longitudinally relative to the rear position.
    In the advanced position, the notch 41 of the cover 30 can be located to the right of the front opening 38a of the yoke while, in the rear position, the notch 41 can be located to the right of the rear opening 38b.
    For this, the cover 30 comprises means for guiding in longitudinal translation intended to cooperate with the yoke 28.
    Each side wall 36a, 36b of the cover 30 comprises a guide rail arranged at its lower longitudinal edge. Each guide rail is in the form of a series of longitudinal flanges 42a, 42b, 42c substantially coplanar which extend transversely inwards.
    The three longitudinal edges 42a, 42b, 42c of each wall 36a, 36b are arranged longitudinally one behind the other and spaced from each other.
    During the longitudinal sliding of the cover 30 along the yoke 28 of the drive arm 14, the flanges 42a, 42b, 42c of the cover 30 can cooperate by sliding with the free lower edges of the side walls 32a, 32b of the yoke 28.
    As illustrated in FIGS. 3, 4 and 15 to 22, a tip 44 of the front longitudinal end is mounted at the free front end of the yoke 28 of the drive arm 14, to close the aforementioned space of the yoke in which is housed an elongated rear body 25, 1025 of the adapter 26, 1026.
    The end piece 44 is in the form of a block of material, preferably elastic, which comprises two opposite lateral ribs 46 for fixing, each of which is formed in relief on a vertical lateral face and extends generally vertically. The end piece 44 is for example produced by injection molding.
    Each fixing rib 46 is intended to be engaged in a front notch 33a of the associated side wall 32a, 32b of the yoke 28, to ensure the fixing and the retention of the end piece 44 on the yoke 28.
    The end piece 44 further comprises a vertical slot 48 able to receive a portion facing the upper part of the deflector 20 of the wiper blade 12.

It has two vertical and longitudinal side walls 26a, 26b which are delimited longitudinally towards the front by a vertical edge 27a, 27b of front longitudinal end and longitudinally towards the rear by a vertical edge 127a, 127b of rear longitudinal end.
    The two side walls 26a, 26b are connected together by a horizontal upper wall 26c.
    The side walls 26a, 26b respectively comprise an orifice 54 and a pin 53 aligned transversely. These elements 53 and 54 are located longitudinally substantially in the middle of the side walls 26a, 26b of the adapter 26.
    In known manner, the elements 53 and 54 define the substantially transverse axis Y of pivoting articulation of the connector 24 relative to the adapter 26, and therefore of the wiper blade 12 relative to the drive arm 14 .
    The connector 24 essentially comprises a lower part 24a for crimping or fixing to the rest of the wiper blade 12, and an upper part 24b intended to be housed between the internal faces of the side walls 26a, 26b of the adapter 26 .
    The upper part 24b comprises means 56 complementary to the elements 53 and 54 intended to be aligned with the axis Y.
    As a variant, one of the components among the adapter 26 and the connector 24 may comprise cylindrical journals centered on the Y axis and intended to be engaged by elastic snap-fastening in an orifice or orifices complementary to the other of these components .
    At its front longitudinal end, the body 25 of the adapter 26 here comprises - without limitation - two retention tabs 62a, 62b each of which extends longitudinally forward in the extension of a side wall 26a, 26b associated with the body 25 of the adapter 26.
    Each retention tab 62a, 62b is shaped to cooperate with the yoke 28 or a component carried by the yoke 28.
    Here, the retention tabs 62a and 62b are intended to be engaged in complementary recesses in the end piece 44 mounted at the free front end of the yoke 28 of the arm, also allowing the adapter 26 to be positioned.
    The retention tabs 62a and 62b are substantially parallel, they each have a generally rectangular parallelepiped shape, and they extend vertically over a major part of the height of the side walls 26a and 26b.
    By way of variant not shown, the body 25 of the adapter 26 may comprise a single retention tab which extends horizontally and longitudinally forward in the extension of the horizontal upper wall 26c of the body 25 of the adapter 26 and which is shaped to cooperate with the yoke 28 or a component carried by the yoke 28.

    Each retaining lug 63a, 63b is shaped to cooperate with the yoke 28 or a component carried by the yoke 28.
    The retaining tabs 63a and 63b are substantially parallel, they each have a generally rectangular parallelepiped shape, and they extend vertically over a lower part of the height of the side walls 26a and 26b.
    In the vicinity of its rear longitudinal end, the body 25 of the adapter 26 comprises a locking tab 100 which is configured to be received through a hole in the yoke 28 which is here the rear opening 38b of substantially rectangular outline of the upper wall 34 of the yoke 28.
    The opening or rear hole 38b is delimited longitudinally towards the rear by a rear transverse edge 39b with which the locking tab 100 cooperates, as will be explained below.
    As can be seen in particular in FIG. 6, the locking tab 100 extends vertically projecting above the horizontal plane of the external face 29 of the upper wall 26c of the body 25 of the adapter 26.
    The retention tabs 62a, 62b and the locking tab 100 are arranged longitudinally on either side of the Y-Y axis of pivoting of the adapter 26 relative to the connector 24.
    The locking tab 100 is disposed longitudinally between the axis Y-Y of pivoting articulation of the adapter 26 relative to the connector 24 and the retaining tabs 63a, 63b.
    The locking tab 100 is configured to be received through the opening 38b of the yoke 28 and it has a free upper part 102 which is shaped into a hook.
    As can be seen in particular in the perspective views of FIGS. 5A and 5B, this hook-shaped part 102 is a solid part which is centered transversely relative to the body 25 of the adapter 26.
    The hook-shaped part 102 has a vertical central branch 104 which is extended by a locking branch 106 which extends longitudinally towards the rear.
    The locking branch 106 is delimited, vertically downwards, by a lower face 108 shaped as a facet, here of generally horizontal orientation which is configured to cooperate with a portion facing the external face of the yoke 28.
    In the mounted and locked position, the lower face 108 bears against a portion 35 of the external surface of the upper wall 34 of the yoke 28 which is located immediately behind the rear transverse edge 39b of the rear opening 38b.
    The vertical branch 104 of the hook-shaped part 102 of the locking tab 100 has a rear surface 110 of contact with the rear transverse edge 39b of the rear opening 38b of the yoke 28.
    The rear contact surface 110 is here - without limitation - a flat surface which extends in a generally vertical plane and which is capable of coming into contact with the rear transverse edge 39b of the rear opening 38b of the yoke 28 which is a straight transverse edge.
    The upper part of the branch 106 for locking the hook-shaped part 102 has a profiled surface portion 112 forming a cam which is able to cooperate with the rear transverse edge 39b of the rear opening 38b of the yoke 28 to cause a longitudinal displacement of the hook 102 forwards with respect to the body 25 of the adapter 26.
    The profiled surface 112 is here a portion of a convex cylinder arc.
    The locking tab 100 is connected to the body 25 of the adapter 26 by a vertical connecting part which is able to deform elastically to allow longitudinal movement - in both directions - of the rear contact surface 110 relative to the body 25 of adapter 26.
    In the embodiment illustrated in FIGS. 3 to 7, the vertical connecting part which connects the locking tab 100 to the body 25 of the adapter 26 comprises two lateral connecting branches 114a, 114b opposite transversely.
    Each connecting branch 114a, 114b extends generally vertically, here with a forward inclination from bottom to top.
    Each connecting branch 114a, 114b extends upwards from the upper face 65a, 65b of an associated retaining tab 63a, 63b, in the vicinity of the rear end of the latter.
    The upper ends of the two connecting branches 114a, 114b are connected together by an upper cross member 116 which extends horizontally and which has a horizontal upper face 118 from which the vertical central branch 104 of the hook-shaped part 102 of the locking tab 100 extends generally vertically upwards.
    The vertical connection part formed by the two connection branches 114a and 114b extends vertically below the horizontal plane of the external face 29 of the upper wall 26c of the body 25 of the adapter 26.
    The vertical connecting part constituted by the two connecting branches 114a and 114b is capable of deforming elastically to pivot relative to the body 25 of the adapter 26, around a transverse axis ZZ which is adjacent to the lower end of each of the two connecting branches 11 4a and 114b.
    This transverse pivot axis Z-Z is disposed vertically below the horizontal plane of the external face 29 of the upper wall 26c of the body 25 of the adapter 26.
    To facilitate the elastic deformation of the vertical connecting part and the pivoting movements around the transverse axis ZZ, a recess 120a, 120b is formed in front of the lower end of the connecting branch 114a, 114b in the part of material which connects the retaining tab 63a, 63b to its associated side wall of the body 25 of the adapter 26.
    The capacity of the lower connection part to deform elastically and to pivot around the transverse axis ZZ is illustrated in FIG. 6 in which the locking tab 100 with its lower connection part is shown in solid line in its free state not deformed, and in dotted lines 100 ′, 114 ′ in a deformed state and pivoted in the counterclockwise direction indicated by the arrow F.
    A step of mounting and assembling the adapter 26 in the yoke 28 is illustrated schematically and partially in FIG. 4.
    As can be seen, after having engaged the retention lugs 62a, 62b in the complementary recesses of the end piece 44 mounted at the front free end of the yoke 28 of the arm, the adapter 26 is brought to the position illustrated in FIG. 4 in which a portion of the convex profiled surface 112 comes into contact with the rear transverse edge 39b of the rear opening 38b of the yoke 28.
    By continuing under effort the relative movement of the adapter 26 relative to the yoke in order to introduce the locking tab 100 through the rear opening 38b, there is a cam effect between the surface 112 and the edge 39b which causes the fastening tab to pivot generally around the transverse axis ZZ.
    As soon as the lower face 108 passes over the outer surface portion 35, the locking tab 100 is returned elastically to its almost non-deformed free state and the rear contact surface 110 comes into contact with the rear transverse edge 39b of the rear opening 38b of the yoke 28, while being in abutment against the latter with a slight elastic load of contact and mutual support generally in the longitudinal direction.
    When it is desired to disassemble the wiper blade, the upper part forming a hook 102 protrudes above the external surface of the upper wall 34 of the yoke 28.
    It then constitutes an unlocking "button" on which the user can act by moving it longitudinally from back to front against the elasticity of the vertical connecting part 114a, 114b.
    To facilitate this action, the convex profiled surface can be notched or provided with any particular suitable surface condition.
    It is desirable to avoid any risk of accidental separation between the wiper arm and the wiper blade, and thus avoid loss of the wiper blade, even under heavy loads.
    Such heavy loads appear in particular when the wiper is used on a glass surface covered with frost or a large layer of snow.
    To this end, in order to avoid any risk of rupture under load of the locking tab 100, and in particular of its free upper part forming a hook 102, the locking branch 106 is able to deform elastically - under the action of a force applied to it by the yoke - relative to the vertical branch 104.
    As can be seen in FIG. 7, and thanks to such an elastic deformation capacity, the locking branch 106 is in particular able to pivot relative to the vertical branch 104, about a transverse axis X-X.
    The transverse axis X-X is here adjacent to the rear end edge of the lower face of the lower face 108 and is substantially adjacent to the vertical branch 104.
    To facilitate the elastic deformation of the locking branch 106 and its pivoting movements around the transverse axis XX, the hook-shaped part 102 has a recess 122 which is formed in the connection zone between the vertical branch 104 and the locking branch 106.
    The recess 122 is here formed in the extension of the lower face 108 of the locking branch 106.
    The recess 122 is a transverse orientation groove.
    As can be seen on a large scale in FIG. 7, the lower face 108 of the locking branch 106 is connected to the groove 122 by a transverse edge 124 which is able to cooperate with the facing portion 35 of the outer surface of the upper wall 34 of the yoke 28.
    The capacity of the locking branch to deform elastically without breaking and to pivot around the transverse axis XX is illustrated in FIG. 7 in which the locking branch 106 is shown in solid lines in its free undeformed state, and in dotted lines 106 ', 108', 1 12 'in a deformed state and rotated counterclockwise.
    The adapter 1026 according to the second embodiment has a shape and a general design substantially similar to that of the adapter 26 of the first embodiment.
    The adapter 1026 has an elongated rear main body 1025 which is shaped to be mounted in the yoke 28.
    In section through a transverse vertical plane, the adapter 1026 has a substantially inverted U shape. It has two vertical and longitudinal side walls 1026a, 1026b which are delimited longitudinally forwards by a vertical edge 1027a, 1027b with a front longitudinal end and longitudinally rearwards with a vertical edge 1127a, 1127b with a rear longitudinal end.
    The two side walls 1026a, 1026b are connected together by a horizontal upper wall 1026c.
    As in the first embodiment, the body 1025 of the adapter 1026 comprises a locking tab 100 configured to be received through a hole in the yoke 28 which is here the rear opening 38b of substantially rectangular outline of the upper wall 34 of clevis 28.
    The locking tab 100 is connected to the body 1025 of the adapter 1026 by a vertical branch 104 which is capable of deforming elastically to allow longitudinal displacement - in both directions - of the rear contact surface 110 relative to the body 1025 of adapter 1026.
    At its front longitudinal end, the body 1025 of the adapter 1026 also includes two retention tabs 1062a, 1062b each of which extends longitudinally forward in the extension of a side wall 1026a, 1026b associated with the body 1025 of the 'adapter 1026.
    The retention tabs 1062a and 1062b are substantially parallel. They each have a general rectangular parallelepiped shape.
    Each of the retention tabs 1062a, 1062b has a lower chamfer 1126a, 1126b which is formed on its lower edge.
    Each retention tab 1062a, 1062b is shaped to cooperate with the yoke 28 or a component carried by the yoke 28. The chamfers 1126a, 1126b make it possible to facilitate the insertion of the adapter 1026 in the yoke 28 or a component carried by the yoke 28, such as the end piece 44 as shown here by way of nonlimiting example.
    The retention tabs 1062a, 1062b allow the vertical retention of the adapter 1026.
    By way of non-limiting example, at its rear longitudinal end, the body 1025 of the adapter 1026 comprises two retaining tabs 1063a, 1063b each of which extends longitudinally towards the rear in the extension of a side wall 1026a, 1026b associated with the body 1025 of adapter 1026.
    Each retaining tab 1063a, 1063b is shaped to cooperate with the yoke 28 or a component carried by the yoke 28.
    The retaining tabs 1063a and 1063b are substantially parallel. They are connected by a transverse and horizontal rear cross member 1128.
    Each of the retaining tabs 1063a, 1063b has a generally rectangular parallelepiped shape, and extends vertically over a lower part of the height of the associated vertical side walls 1026a and 1026b.
    The retaining lugs 1063a, 1063b have a rear end which abuts on the yoke 28 or a component carried by the yoke 28.
    The rear cross member 1128 extends horizontally between the two retaining lugs 1063a, 1063b. It connects the rear ends of the retaining lugs 1063a, 1063b.
    The width of the rear cross member 1128 - measured in the longitudinal direction - corresponds to more than half the length of the retaining tabs 1063a, 1063b.
    The length of the retaining tabs 1063a, 1063b is dimensioned so that the rear end of each of the retaining tabs 1063a, 1063b comes into abutment with the yoke 28 or a component carried by the yoke 28.
    The retaining tabs 1063a, 1063b are thus used for the longitudinal retention of the adapter towards the rear. They make it possible, in particular to avoid deterioration of the locking tab 100 in the event that the brush is pulled longitudinally towards the rear relative to the yoke 28.
    The rear cross member 1128 makes it possible to reinforce the rigidity of the rear end part of the adapter 1026, in particular to reinforce the rigidity of the retaining lugs 1063a, 1063b.
    By way of non-limiting example, at its front longitudinal end, the body 1025 of the adapter 1026 comprises two front stops 1029a, 1029b of curved or curved convex profile delimiting for each of these stops a convex curved surface of stop 1130a, 1130b for positioning longitudinally the adapter
    1026 relative to the yoke 28 or a component such as the end piece 44 carried by the yoke 28.
    Each of the stops 1029a, 1029b extends vertically downward following a curve in the extension of a side wall 1026a, 1026b associated with the body 1025 of the adapter 1026.
    Each of the curved stops 1029a, 1029b is attached laterally to an external face of an associated retention tab 1062a, 1062b.
    The longitudinal thickness of each stop 1029a, 1029b decreases vertically from top to bottom so as to have a convex curved profile oriented towards the front (See Figure 12).
    Thus, the convex abutment surface 1130a, 1130b has an upper transverse edge which is offset longitudinally forward with respect to a lower transverse edge of the convex abutment surface 1130a, 1130b.
    The convex curved stops 1029a, 1029b allow the longitudinal positioning of the adapter on the yoke 28 or a component carried by the yoke 28, such as the end piece 44.
    When assembling the adapter 1026 and the yoke 28 associated with the end piece 44, the convex abutment surface 1130a, 1130b of the curved abutments 1029a, 1029b comes to bear longitudinally on a portion of the yoke 28 or of the 'end piece 44, opposite (See Figure 21). The curved profile of the curved stops 1029a, 1029b thus serves as an assembly guide allowing a longitudinal pre-positioning of the adapter 1026 in the yoke 28.
    This pre-positioning is carried out gradually and the convex surfaces facilitate the relative pivoting movement of the adapter relative to the yoke during assembly.
    Without limitation, each of the side walls 1026a, 1026b has an elastically deformable tab in the transverse direction, called elastic tab 1132a, 1132b.
    The elastic tabs 1132a, 1132b are located on a front part or portion of the side walls 1026a, 1026b. They extend substantially over 20% to 50% of the length of the side walls, or even preferably from 25% to 35% of this length.
    Each of the elastic tabs 1132a, 1132b has a general longitudinal orientation parallel to the upper wall 1026c, that is to say a horizontal orientation.
    Each elastic tab 1132a, 1132b is delimited by two horizontal parallel slots 1136a, 1136b and a vertical perpendicular slot before 1138a, 1138b connecting the two parallel slots 1136a, 1136b. The slots are through and formed in the corresponding side wall 1026a, 1026b.
    In a variant not shown, it can also be envisaged that the elastic tabs have a general vertical orientation orthogonal to the upper wall 1026c.
    The free front end of each of the elastic tabs 1132a, 1132b here comprises a lug, or tooth, of retaining 1134a, 1134b longitudinal configured to cooperate with the yoke 28 and / or a component carried by the yoke 28 and / or the cover 30 .
    The retaining lugs 1134a, 1134b project transversely outward relative to the plane of the associated elastic tab 1132a, 1132b.
    The pins have a triangular cam profile with an upper slope 1133a, 1133b, a lower slope 1135a, 1135b, a front face 1137a, 1137b and a rear face 1139a, 1139b.
    The front face 1137a, 1137b of each of the retaining lugs 1134a, 1134b comes to bear longitudinally on the yoke 28. The retaining lugs 1134a, 1134b thus allow a longitudinal securing towards the front of the adapter 1026 relative to the yoke 28.
    The length of the upper slope 1133a, 1133b is greater than the length of the lower slope 1135a, 1135b.
    The upper slope 1133a, 1133b of the retaining lugs 1134a, 1134b allows the retraction of each of the elastic tabs 1132a, 1132b for the passage at the level of the longitudinal edge 42a located at the front of the cover 30 during assembly of the adapter 1026 in clevis 28.
    The lower slope 1135a, 1135b of the retaining lugs 1134a, 1134b allows the retraction of each of the elastic tabs 1132a, 113b2 for the passage at the level of the longitudinal edge 42a situated at the front of the cover 30 during the dismantling of the adapter 1 026.
    Because of its elasticity and the triangular profile of their retaining lugs 1134a, 1134b, the elastic tabs 1132a, 1132b do not participate in a vertical retention of the adapter 1026 relative to the yoke and / or the cover 30. On the other hand , the elastic tabs 1132a, 1132b are used for the final longitudinal positioning of the adapter 1026.
    In another variant not shown, the profile of the lugs 1134a, 1134b may be in the form of a trapezoid having an upper slope and a lower slope. The operation of the elastic tabs is then substantially similar.
    The side walls 1026a, 1026b comprise studs 1140a, 1140b, 1142a, 1142b projecting and configured to cooperate with the yoke 28 and / or the cover 30. The studs 1140a, 1140b, 1142a, 1142b project transversely outwards and each have a general cubic shape.
    In the second embodiment, each of the side walls 1026a, 1026b comprises, without limitation, two front studs 1140a, 1140b, and two rear studs 1142a, 1142b.
    The front studs 1140a, 1140b are located on a front part of the side walls 1026a, 1026b. They are configured to cooperate with the cover 30 and come to bear against the front end of the notch 42a of the cover 30.
    The front studs 1140a, 1140b guarantee that the cover 30 is in the closed position, slid backwards relative to the yoke 28 when the adapter 1026 is mounted.
    In fact, in the open position sliding towards the front of the cover 30, the flanges 42b of the cover 30 are found under the location intended to receive the front studs 1140a, 1140b preventing the mounting and assembly of the adapter 1026 in the clevis 28.
    The rear studs 1142a, 1142b are located on a rear part of the side walls 1026a, 1026b. In the embodiment shown, the rear studs 1142a, 1142b project transversely from the retaining lugs 1063a, 1063b.
    The rear studs 1142a, 1142b are configured to cooperate with the yoke 28, in particular with the rear notches 33d. They are in abutment against the front edge of the associated rear notch 33d so as to provide longitudinal retention towards the rear of the adapter 1026 relative to the yoke 28.
    Thus, the retaining pins 1134a, 1134b of the elastic tabs 1132a, 1132b and the front studs 1140a, 1140b allow a double longitudinal securing towards the front of the adapter 1026 relative to the yoke, in particular under high force (s) ( s).
    The rear studs 1142a, 1142b also bear slightly upwards against the horizontal upper edge of the rear notches 33d.
    The bottom of the side walls 1026a, 1026b comprises a bottom part 1143a, 1143b having a rounded convex contour in an arc of a circle.
    In the second embodiment, this rounded bottom part 1143a, 1143b is formed with an external lateral allowance, thereby reinforcing the rigidity of the lower part of the side walls 1026a, 1026b.
    This extra thickness allows better resistance to torsion and deformation that the 1026 adapter could undergo in the event of heavy loads which may appear when using the wiper on a glass surface covered with frost or a layer of snow.
    In fact, once the adapter 1026 is mounted on the wiper blade 12, the lower part of the adapter 1026 is in the open air and it can be attacked by the outside environment, in particular in the event of weather conditions. difficult, like snow or frost.
    The lower part 1143a, 1143b of the adapter 1026 further comprises a protrusion 1144a, 1144b of rounded shape.
    As can be seen in FIG. 20, the rounded protrusion 1144a, (1144b) is in pivoting abutment on an upper lateral facet opposite 1145a, (1145b) of the connector 24 so as to ensure vertical retention towards the bottom of the adapter 1026 relative to connector 24.
    The adapter 1026 here comprises at least one grip zone 1146 and 1148 for positioning suction cups for gripping the adapter 1026 by a machine during its factory mounting on a wiper blade 12.
    For example, the rear cross member 1128 has a horizontal rear extension 1146 corresponding to a first gripping area. The rear extension 1146 includes a rounded rear edge allowing the rear cross member 1128 to be extended and facilitating the positioning of a gripping suction cup (not shown).
    The horizontal upper wall 1026c also has a horizontal upper extension 1148 with a rounded rear edge corresponding to a second gripping zone.
    In an alternative embodiment not shown, the upper wall of the body of the adapter may include a deformable tongue elastically configured to bear against the internal face of the upper wall of the yoke, in order to eliminate any play between the adapter and this internal face.
    Such a play take-up tab is for example located in the vicinity of a front longitudinal end of the body, and the locking tab 100 is located at an opposite rear longitudinal end of the body.
    The mounting and assembly of the adapter 1026 in the yoke 28 is similar to that described with reference to the first embodiment.
    The mounting of the adapter 1026 is done, and can only be done, when the cover 30 is in the closed position, slid backwards.
    Initially, the retention tabs 1062a, 1062b are engaged in the complementary recesses of the end piece 44 mounted at the free front end of the yoke 28 of the arm. Their engagement is facilitated by the presence of the chamfer 1126a, 1126b.
    The adapter 1026 is then brought to the position illustrated in FIG. 4 by an upward tilting of the adapter 1026.
    The tilting of the adapter 1026 is facilitated by the curved stops 1029a, 1029b which bear longitudinally on the end piece 44.
    During tilting or pivoting, the retaining lugs 1134a, 1134b of the elastic tabs 1132a, 1132b are retracted by virtue of the upper slope 1133a, 1133b so as to be able to pass over the longitudinal edge 42a located at the front of the cover 30.
    The front face 1137a, 1137b of the retaining pins 1134a, 1134b comes to bear on the yoke 28 while ensuring longitudinal retention towards the front of the adapter 1026.
    Then, the front studs 1140a, 1140b pass at the edges 42a of the cover 30, ensuring that the latter is in the closed position.
    Finally, the rear studs 1142a, 1142b are inserted into the rear notches 33d and abut against the front edge of the rear notches 33d so as to provide longitudinal retention towards the rear of the adapter 1026.
    The adapter is then in the position illustrated in particular in FIGS. 1 6 to 22.
    In this position, a portion of the convex profiled surface 112 comes into contact with the rear transverse edge 39b of the rear opening 38b of the yoke 28.
    The locking of the locking tab 100 in the rear opening 38b of the yoke 28 is then done as for the first embodiment.
    To disassemble the adapter 1026 of the second embodiment of the wiper blade 12, the procedure is similar to disassembly of the adapter 26 of the first embodiment.
    Once the locking tab 100 unlocked and out of the rear opening 38b, by tilting down the adapter 1026, the retaining pins 1134a, 1134b of the elastic tabs 1132a, 1132b retract thanks to the lower slope 1135a , 1135b in order to ensure their passage at the level of the longitudinal edge 42a situated at the front of the cover 30.
    The adapter 1026 can finally be completely dismantled by disengaging the retention lugs 1062a, 1062b outside the complementary recesses of the end piece 44 of the yoke 28 of the arm.
