    TECHNICAL AREA
    The present disclosure relates to a glazing, in particular a vehicle glazing.
    More specifically, it relates to glazing of the type comprising a laminated glazed element comprising an outer glass sheet, an inner glass sheet, and at least one plastic interlayer sheet located between said glass sheets, said outer glass sheet having an outer face, an edge and an insert face which is oriented towards said plastic interlayer sheet, said inner glass sheet having a spacer face which is oriented towards said plastic interlayer sheet, a edge and an inner face, and said glazing comprising, along at least one part of at least one edge, a profile comprising a functional part provided with a groove and a fixing part for fixing it to the glazed element.
    BACKGROUND OF THE INVENTION
    Vehicle glazing, including windshields and rear goggles, is commonly associated with stormwater collection or disposal systems.
    Glazing is thus known comprising, along at least one part of at least one edge, a section comprising a groove that can be used for clipping a covering piece, for example an awning grid, or else for recovering and the drainage of runoff.
    Such a profile is generally attached to the inner face of the glazed element (or inner face of the inner glass sheet) with the aid of an inner wing which is glued against this inner face.
    For good adhesion of this inner wing to the glazed element, this inner wing must be relatively wide (when the profile is observed in cross section). The prior art has two types of situations: when the cover piece covers at least the groove protruding above the outer face of the glazed element, as for example in patent applications EP 945 296, DE 3606566; and when the covering piece covers at least the groove without protruding above the outer face of the glazed element, as for example in the patent applications WO 2001/045974 or WO 2001/85481.
    In the first situation, the cover piece must be sufficiently wide, to cover at least the inner wing so that it is not visible from the outside and / or a masking tape is made outside more than the outside. inner wing.
    In the second situation, a masking tape is made more outward than the inner wing to cover at least the inner wing so that it is not visible from the outside.
    These two situations have in common that the cover piece and / or the masking tape are, themselves or together, at least as wide as the inner wing and generally wider than the inner wing; as a result, the clear view through the glazed element is diminished.
    In addition, because of the presence of the inner fender at the corner between the edge of the inner glass sheet and its inner face, the bead of glue that adheres the glazing to the adjacent bodywork must be positioned more towards the center glazing; however, this bead of glue must also be masked from the outside.
    Thus, it is common to consider that along the edge of a glazing equipped with a groove profile, it is a band 30 to 35 mm wide which can not be used to allow light to pass through and which decreases the clarity of view.
    OBJECT AND SUMMARY OF THE INVENTION One of the objectives of the present invention is to provide a glazing solution overcoming the drawbacks of the prior art, incorporating a profile for the management of water which is firmly attached to the glazed element, and to increase the clarity of view through the glazed element.
    This objective is achieved with a glazing, in particular a vehicle glazing, comprising a laminated glazed element comprising an outer glass sheet, an inner glass sheet, and at least one plastic interlayer sheet located between said glass sheets, said sheet outer glass member having an outer face, an edge and a spacer face which is oriented towards said plastic interlayer sheet, said inner glass sheet having an intermediate face which is oriented towards said plastic interlayer sheet, a edge and a face interior, and said glazing having, along at least a portion of at least one edge, a profile having a functional portion provided with a groove and an attachment portion for attachment to the glazed element, the glazing being characterized in that the attachment portion comprises an intermediate wing which, when viewed in cross-section, is ituates between the intermediate face of said outer glass sheet and the intermediate face of said inner glass sheet, said intermediate wing having an outer face facing the outer glass sheet, an inner face facing the inner glass sheet and a singing , and in that at least one face of the inner face and the outer face of the intermediate wing is in contact with said at least one plastic interlayer sheet.
    According to the invention, the intermediate wing of the profile is attached to the glazed element through the interleaf (s) or sheets (s) of plastic. The intermediate wing being laminated between the outer and inner glass sheets of the glazed element, fixing is much safer than with a simple bonding on an inner face of the glazing. The section of the fixing wing can be narrower, and the clear view of the glazing, increased. Furthermore, the glazing according to the invention is easy to assemble.
    Cross-sectional view, the functional part of the profile has a hook shape. In some applications of the invention, this form allows the reception and direct evacuation of rainwater. The groove then serves as an evacuation channel or gutter. In other applications, the groove is intended to cooperate with a covering part whose particular function is the management of runoff, for example a canopy grille.
    In the present disclosure, an interlayer sheet of plastic material is to be understood as any sheet for ensuring adhesion between the outer glass sheet and the inner glass sheet, so as to obtain a laminated glazing. Such a sheet is typically PU (polyurethane) or PVB (polyvinyl butyral) or EVA (ethylene vinyl acetate copolymer).
    Typically, the edge of the intermediate wing is also in contact with said at least one plastic interlayer sheet.
    According to one example, the outer face of the intermediate wing and the edge of the intermediate wing are in contact with the at least one plastic interlayer sheet and the inner face of the intermediate wing is connected, by contact or by means of intermediate of a layer of adhesive material, with the intermediate side of the inner glass sheet. Thanks to these provisions, the stresses applied to the profile during the fixing of the cover piece on the groove are partially covered by the inner glass sheet. The plastic interlayer sheet thus undergoes less stress, and the attachment of the intermediate wing to the glazed element is preserved.
    According to one example, the glazed element comprises at least one outer interlayer sheet and an inner plastic interlayer sheet between the outer glass sheet and the inner glass sheet, the outer face of the intermediate wing being in contact with the sheet outer spacer and the inner side of the intermediate wing being in contact with the inner spacer sheet.
    According to one example, the glazed element further comprises a third plastic interlayer sheet between the outer intermediate sheet and the lower interlayer sheet, the edge of the intermediate wing being in contact with the edge of said third interlayer sheet.
    Glazing according to the invention is generally intended to achieve a separation between an outer space E and an interior space I, of a vehicle for example. The notions of "outside" and "inside" are therefore considered with respect to this outer space E and this interior space I.
    For the present disclosure, in any transverse plane of the glazing, a main direction orthogonal to the tangent to the outer face of the outer glass sheet of the glazed element is also defined, at the junction of said outer face and the edge of said sheet.
    In the same transverse plane, a lateral direction, orthogonal to said main direction, is defined.
    In this presentation, the adjectives "distal (e)" and "proximal (e)" are used to define portions of a profile. It will be considered in particular that in a transverse plane, a distal portion of the profile is further away (or intended to be further away) from the glazed element (generally in a direction orthogonal to the opening direction of the groove), that a proximal part of the same section.
    In one example, the groove has its opening oriented in the main direction. The groove may also have its opening oriented in the lateral direction.
    In one example, the groove is open to the outside.
    In one example, the profile has, in cross section, two open recesses in the same direction or in opposite directions, a first recess forming the groove and a second recess embedding the outer glass sheet.
    The profile can thus have, in cross-section, a shape of m or S.
    In one example, the spacer wing has a width (measured in the lateral direction) of between 5 and 40 mm, in particular between 5 and 20 mm.
    To prevent delamination due to its expansion, the intermediate wing may possibly be corrugated. In particular, the intermediate wing may have corrugations, seen in a longitudinal plane orthogonal to the lateral direction. According to one variant, it can also present undulations, seen in a transverse plane.
    In one example, the profile comprises at least one body portion of thermoplastic material delimiting the groove, and at least one fixing insert having a distal portion inserted into said body portion and a proximal portion protruding out of said body part.
    In this case, the spacer wing may be constituted, at least in part, by said proximal portion of the fixing insert. The fixing insert is for example made of a metallic material. More generally, the fixing insert is made of a material having a coefficient of expansion substantially identical to that of glass.
    To improve the attachment of the profile to the glazed element, the intermediate wing may have at least one cavity, in particular at least one through opening. According to one arrangement, the cavity extends in the main direction. At the time of manufacture, the plastic material constituting the at least one spacer sheet penetrates into said cavity, reinforcing the resistance of the fastener against a tearing force in the lateral direction.
    Preferably, the spacer wing has a plurality of cavities, in particular through openings, distributed regularly or not, over its entire surface.
    In one example, the profile extends along the entire length of at least one edge of the glazed element.
    In one example, the profile is located along two lateral edges of the glazed element and / or along an upper edge of the glazed element.
    In one example, the profile is located along a lower edge of the glazed element.
    In one example, the profile is provided with a sealing lip between the groove and the intermediate wing.
    Typically, the sealing lip is in contact with the edge of the outer glass sheet.
    In one example, the groove is configured for clipping a cover piece on said profile.
    The present disclosure also relates to an assembly, comprising a glazing unit as defined above, in which the groove is configured for clipping a cover piece on said profile, and a covering piece comprising, in cross-section, a penetrating spear. in the groove when clipping.
    The cover piece is for example a canopy grille or a hubcap.
    The present disclosure also relates to an assembly, comprising a glazing as defined above, and a bodywork part, the profile being supported on said bodywork part.
    In one example, the bodywork part has a main portion and an end portion recessed inwardly relative to said main portion and connected thereto by a shoulder, and the functional portion of the profile bears against the shoulder, and the glazed element is fixed by bonding to said end portion.
    According to a particular arrangement, the functional part of the profile is elastically deformed against the bodywork part, so as to ensure a sealed contact with said part.
    According to a preferred arrangement, the functional part of the profile matches the shape of the bodywork part.
    The present disclosure also relates to a profile for a glazing unit as defined above, comprising at least one body part made of thermoplastic material delimiting a groove, and at least one fixing insert provided with a distal portion inserted into said body part and a proximal portion projecting from said body portion.
    Such a profile is for example made by overmolding the fixing insert by the body portion. It could also be made by extrusion, in particular in the case of rectilinear sections with constant section. The fixing insert is typically made of a metallic material.
    In one example, the body portion is further reinforced by at least one reinforcing insert separate from the attachment insert.
    According to one example, the attachment insert extends substantially along the entire internal contour of the groove, seen in cross section. In other words, the fixing insert extends continuously over at least 80% of the internal contour of the groove.
    In one example, the spacer wing has a plurality of cavities, and in particular through openings.
    The present disclosure also relates to a method of manufacturing a glazing unit as defined above, comprising a step of lamination of the outer glass sheet and the inner glass sheet of the glazed element by means of at least one intermediate sheet of plastic material, the lamination step comprising the disposition of the intermediate wing of the profile between the outer glass sheet and the inner glass sheet, in contact with the at least one interlayer sheet.
    It is understood that the profile is integrated in the glazing at the time of lamination.
    Typically, the intermediate wing of the profile is superimposed with one of the inner glass sheet and the outer glass sheet to form a first stack, before the other glass sheet is disposed on said first stack.
    According to an example of a particular implementation, the lamination step comprises the following substeps: a1) a first plastic spacer sheet is deposited on a first glass sheet, b1) the intermediate wing is superimposed with said first sheet of glass; interlayer sheet, the first sheet of glass, the first interlayer sheet and the intermediate wing forming a first stack, cl) a second sheet of glass is disposed on the first stack, the intermediate wing being arranged between the first and second sheet of glass and attached to said glass sheets via the first intermediate sheet.
    According to an example, prior to sub-step c1), at least a second plastic spacer sheet is deposited on the second glass sheet or on the first stack, the intermediate wing being thus disposed, at the end of the sub-step c1) between the first and second intermediate sheets.
    According to another example of particular implementation, the lamination step comprises the following substeps: a2) the intermediate wing is superimposed with a first sheet of glass, the first sheet of glass and the intermediate wing forming a first stack, b2) at least one plastic interlayer sheet and a second glass sheet are disposed on the first stack, the intermediate flange thus being disposed between the first and second glass sheets and secured to said glass sheets by the intermediate of the intermediate sheet.
    In one example, during the sub-step a2), the intermediate wing is attached to the first glass sheet by means of a layer of adhesive material.
    According to one example, the intermediate wing is formed by a proximal portion of an insert, so that after the lamination step, a distal portion of the insert projects out of the laminated glazed element, and the method further comprises, after the lamination step, a step of coating said distal portion of the insert protruding from the laminated glazed element, in particular by overmolding
    Several examples of implementation or implementation are described in this presentation. However, unless otherwise specified, the features described in connection with any exemplary embodiment or implementation may be applied to another embodiment or implementation.

DETAILED DESCRIPTION OF EMBODIMENTS The present invention relates to glazing of the type comprising a laminated glazed element comprising an outer glass sheet, an inner glass sheet, and at least one plastic interlayer sheet between said glass sheets. By way of example, examples of glazing according to the invention will be described hereinafter with reference to the appended figures, in the context of applications as vehicle windows * these glazings providing a separation between an outer space E which is outside the vehicle and an interior space I which is inside the vehicle.
    In the example of Figure 1, the invention is applied to a vehicle windshield and more particularly to a lower edge of a vehicle windshield. Figure 1 is a cross-sectional view of the glazing 1 installed in a body berry, and intended to close said bay. An edge of this bay is illustrated in Figure 1 by a rabbet 9.
    In the example, the glazing 1 comprises a laminated glazing element 2 comprising an outer glass sheet 3, an inner glass sheet 5 and two interlayer plastic sheets 41, 42 located between said two glass sheets 3, 5.
    The outer cover sheet 3 has an outer face 3a which faces outwards (E), an intermediate face 3b which is oriented towards the plastic interlayer sheets 41, 42 and a lip 3c situated between these two faces. for example a thickness 03 between 1.8 and 2.5 millimeters.
    The inner glass sheet 5 has an intermediate face 5a which is oriented towards the interlayer sheets of plastic material 4, 4 ', an inner face 5b which is oriented towards the inside I and a edge 5c situated between these two faces. It has for example a thickness e5 of between 1.2 and 2.5 millimeters.
    The outer intermediate sheet 41 has an outer face 41a which is oriented towards the intermediate face 3b of the outer glass sheet 3 and which is here in contact with this intermediate face 3b, an inner face 41b which is oriented towards the intermediate face 5a of the inner glass sheet 5, and a song 41c.
    The inner spacer sheet 42 has an outer face 42a which is oriented towards the intermediate face 3b of the outer glass sheet 3, an inner face 42b which is oriented towards the intermediate face 5a of the inner glass sheet 5 and which is here at contact of this intermediate face 5a, and a song 41c.
    In the example, the interlayer sheets 41, 42 both have the same thickness (for example 0.36mm, or 0.72mm). According to one variant, they could also have different thicknesses.
    They are for example made of PVB. The glazed element 2 thus has an outer face formed by the outer face 3a of the outer glass sheet 3, an inner face formed by the inner face 5a of the inner glass sheet 5 and a corresponding edge between these two faces. at the edge 3c of the outer glass sheet 3, the edge 5c of the inner glass sheet 5 and the edges 41c, 42c of the two interlayer sheets of plastic material, these edges being here in continuity with each other.
    The glazing 1 is intended to be adhered to the body rabbet 9 by means of a bead of glue C, which is located between the inner face 5b of the inner glass sheet 5 and an adjacent part of the rabbet 9.
    The glazing 1 comprises, in addition to the glazed element 2, along at least part of its edge (here below), a section 6 comprising, seen in cross-section, a functional part 60 provided with a receiving housing or groove 61 here intended for clipping a cover piece 8 on said profile 6, and a fixing portion 70 for attachment to the glazed element comprising an intermediate wing 71 located between the intermediate face 3b of the outer glass sheet 3 and the intermediate side 5a of the inner glass sheet 5.
    In the cross-section of FIG. 1, a principal direction Y orthogonal to the tangent to the outer face 3a of the outer glass sheet 3 of the glazed element 2 is defined at the junction point of said outer face 3a and the edge 3c of said sheet 3.
    A lateral direction X, orthogonal to said main direction Y, is also defined.
    The longitudinal direction Z is the direction orthogonal to the aforementioned X and Y directions.
    In the example, the section 6 is a composite element comprising a core or attachment insert 64, here metallic, and a body portion of thermoplastic material 65 surrounding a portion of said fixing insert.
    The body portion 65 made of thermoplastic material is for example overmolded around the fixing insert 64.
    It could also be extruded around the fixing insert 64, in the case of two-dimensional pieces (with constant cross section).
    As will be described in more detail in the following, it may be monolithic (i.e. without interface in the material), or consists of several subparts (connected by one or more interfaces), including subparts of different materials.
    The functional part 60 of the profile 6 is constituted by the body portion of thermoplastic material 65 delimiting the groove 61, a distal portion of the fixing insert 64 being inserted into said body portion 65, for its attachment to said portion of In the particular example of FIG. 1, the distal portion of the fixing insert 64 has a curved shape corresponding substantially to the profile of the groove 61.
    According to a variant, the distal portion of the fixing insert 64 may extend over a limited portion of the body portion 65, which may optionally be stiffened by one or more other reinforcing insert (s).
    A proximal portion of the insert projects out of the body portion. It is this proximal portion of the insert 64 which forms here the intermediate wing 71 of the profile. The intermediate wing 71 has an outer face 71a facing the outer glass sheet 3, an inner face 71b facing the inner glass sheet 5 and a 71c edge located between these two faces.
    In the example illustrated in FIG. 1, more particularly, the intermediate wing 71 is disposed between the two interlayers of plastics material 41, 42.
    The outer face 71a of the spacer wing 71 is in contact with the inner face 41b of the outer spacer sheet 41 and the inner face 71b of the intermediate wing 71 is in contact with the outer face 42a of the inner spacer sheet 42.
    The edge 71c of the intermediate flange 71 is in contact with one or the other or the two intermediate sheets 41, 42. It is the latter case which is illustrated in FIG. 1, and can be seen more clearly on the detail of Figure IA. The intermediate wing 71 has a thickness e7 less than the sum of the thicknesses of the two interlayer plastic sheets 41, 42. It does not come into contact with the intermediate faces of the outer and inner glass sheets 3, 5. L The intermediate wing 71 has a width I, measured in the lateral direction X, of between 5 and 40 mm, or even between 5 and 20 mm. This width is sufficient to allow a good maintenance of the spacer wing 71 between the outer spacer sheet 41 and the inner spacer sheet 42 without the risk of disturbing the cohesion of the two glass sheets 41, 42.
    Preferably, the profile 6 extends continuously over the entire length (or substantially the entire length) of the lower edge of the glazing 1.
    In the example, the groove 61 is open to the outside.
    The cover piece 8 is here intended to be positioned more outwardly than the profile 6 and to cover at least in part when the glazing 1 is viewed from the outside E. This is, in the context of the application to a lower edge of a windshield, an awning grid designed to make a visual connection between the windshield and the engine hood, while channeling the runoff and ensuring in the same time a ventilation of the engine compartment through ventilation openings (not shown). An awning grid is typically made of a plastic material. As an alternative, particularly in the context of an application to a side edge or upper side windshield, the cover piece could also be a hubcap intended to limit the penetration of water on the side of the glazing through the presence of a lip located against the rabbet 9.
    In the example, the outer face 8a of the awning grid, substantially flat, is intended for the evacuation of runoff, including rainwater dripping on the windshield, and an inner face 8b opposite is provided a harpoon 80 for penetrating into the groove 61 of the profile 6 during clipping.
    The groove 61 has a mouth and a bottom: when clipping the cover piece 8, the harpoon 80 enters the groove 61 through the mouth and towards the bottom; generally, in the clipped position, the harpoon 80 does not touch the bottom of the groove. The mouth of the groove, through which the harpoon 80 is introduced, is made by two gutters: a distal gully 67, situated to the left of the harpoon 80 in FIG. 1 and a proximal gully 68, situated to the right of the harpoon 80 on this same figure. These two drains are intended to guide the harpoon 80 accurately to the bottom of the groove 60 during clipping.
    The two drains 67, 68 of the mouth of the groove 61 are each in the form of a hammer with the heads almost opposite one another.
    Spear 80, meanwhile, is double: it is constituted, seen in cross section, two bosses facing away from one another.
    The clipping thus consists in the penetration of the harpoon 80 inside the groove 61 and more precisely the two bosses of the harpoon inside the groove 61 and under the two drains.
    For proper restraint, the width of the mouth, the shorter between the two drains 67, 68 is less than the width of the two bosses at the widest.
    In this first mode, as illustrated in FIG. 1, the groove 61 does not protrude from an artificial plane situated in the continuity of the outer surface 3a of the outer glass sheet 3: the profile is flush with the outer surface 3a of the outer glass sheet 3.
    The distal outer edge of the functional portion 60 (on the groove 61 side furthest from the glazing element 2 in FIG. 1) is located less outward than the proximal outer edge of said portion 60 (on the the groove 61 closest to the glazed element 2 in Figure 1) so that when the cover piece 8 is clipped into the groove 61 an outer face 8a of the cover piece 8 can be in continuity with the outer surface 3a of the outer glass sheet 3; it is said that the cover piece is "flush" with the outer glass sheet 3. The profile 6 does not protrude further outside than the outer face 3a of the outer glass sheet 3.
    It is thus also possible that the cover piece 8 is present above the groove 61 but does not protrude above the outer face 3a.
    The bottom of the groove 61 may itself be located more inside than the inner face 5b; this does not interfere with the positioning of the glazing in the bay of the bodywork because there is room between the inner face 5b and the rebate 9 for the adhesive bead C.
    The profile 6 is thus laminated between the two glass sheets 3, 5 of the glazed element and fixed to these sheets 3, 5 by means of plastic sheets 41, 42, also known as "interleavers". "Laminating". These plastic sheets 41, 42 here ensure both the attachment of the glass sheets 3, 5 to each other, and the attachment of the profile 6 to the glazed element 2.
    The profile 6 is, at least partly, integrated in the glazed element 2 at the time of lamination.
    Figure 11 illustrates different manufacturing steps of the glazing 1 of Figure 1, according to a possible implementation mode.
    In a first step (A), the inner spacer sheet 42 is deposited on the intermediate face 5a of the inner glass sheet 5.
    In a second step (B), the profile 6 is arranged so that the intermediate wing 71 is superimposed with said inner spacer sheet 42. At this time, the inner glass sheet 5, the inner spacer sheet 42 and the wing interlayer 71 form a first stack.
    In a third step (C), the upper intermediate sheet 41 is disposed on the first stack.
    In a fourth step (D), the outer glass sheet 3 is disposed on the upper intermediate sheet 41. The intermediate wing 71 is thus disposed between the outer glass sheet 3 and the inner glass sheet 5 and attached to said sheets of glass 3, 5 through the interlayer plastic sheets 41, 42.
    Then a sufficient pressure is applied on the assembly to adhere the different layers together by means of the interlayers of plastic material 41, 42, in a vacuum bag, between rolling rolls (when the profile 6 does not exceed beyond the extension of the outer and inner faces 3a, 5b of the glazed element 2), or in an autoclave.
    In the illustrated example, the profile 6 is formed with its body portion of thermoplastic material 65 before the lamination step.
    According to an alternative embodiment, the body portion 65 may also be formed around the distal portion of the fixing insert 64 projecting out of the glazed element 2, after lamination. According to one possible embodiment, the steps A to D may be identical to those described above but successively by a step E of coating the distal portion of the fixing insert 64 protruding from the glazed element 2 as illustrated in FIG. 12. The coating step E is, for example, a step of overmoulding at least one portion of the distal portion of the insert 64 by the body portion made of thermoplastic material 65. implementation has the advantage of allowing, for the body portion 65, the use of materials incompatible with the lamination step, for example materials not resistant to high temperatures or pressures.
    According to another variant, it is possible to start the stacking not on the intermediate face 5a of the inner glass sheet 5 but on the intermediate face 3b of the outer glass sheet 3.
    One could also pre-assemble at least one of the glass sheets with a plastic interlayer sheet. In the example of Figure 11 for example, one could pre-assemble the plastic interlayer sheet 41 and the outer glass sheet 3 before disposing the assembly pre-assembled on the first stack.
    FIG. 2 illustrates a variant of profile 6 that can be used in a glazing unit according to the invention, in which the intermediate wing 71 formed by the proximal part of the fixing insert 64 has a plurality of through openings 75, here distributed regularly on its surface. These openings open at the same time on the outer face 71a and on the inner face 71b of the intermediate wing 71.
    Alternatively, the spacer wing 71 may comprise one or more non-through cavities, opening on only one of its outer face 71a and its inner face 71b.
    During assembly, under the effect of pressure, the plastic material constituting the intermediate sheet (s) 41, 42 penetrates inside the cavities of the intermediate wing 71, reinforcing the fixing of the profile 6 on the glazed element 2.
    Figure 3 illustrates yet another variant of section 6 can be used in a glazing according to the invention, wherein the intermediate wing 71 is corrugated.
    In the example shown, the intermediate wing 71 has a wave shape in longitudinal section (i.e. in a plane orthogonal to the X axis, containing Y and Z).
    According to one variant, it could have a wave shape in cross section.
    FIG. 4 illustrates a glazing unit 1 according to another embodiment, in which the groove is open in the lateral direction.
    The profile 6 has, in cross section, a shape of m. A first hollow of the m realizes the groove 61 to accommodate the harpoon 80 of the cover piece 8 and a second hollow of the m entrains the outer glass sheet 3, preferably coming against the edge 3c of the outer glass sheet 3.
    FIG. 5 illustrates a glazing unit 1 according to another embodiment, in which the groove is open in the lateral direction.
    The profiled bead 6 has here, in cross-section, an S-shape. A first recess of the S (the upper recess, open to the left in FIG. 5) provides the groove 61 for receiving the spear 80 of the cover piece 8 and a second recess of the S encases the outer glass sheet 3, preferably coming against the edge 3c of the outer glass sheet 3.
    FIG. 6 illustrates a glazing unit 1 according to another embodiment of the invention, in which the outer face 71a and the edge 71c of the intermediate flange 71 are in contact with the plastic interlayer sheets 41, 42. More particularly in the example shown, the outer face 71a of the intermediate wing 71 is in contact with the upper intermediate sheet 41, and its edge 71c, with the lower intermediate sheet 42.
    The inner face 71b of the intermediate wing 71 is connected by means of a layer of adhesive material 77 to the intermediate face 5a of the inner glass sheet 5.
    Thanks to these provisions, the forces applied to the wing insert during clipping of the cover piece 8 on the groove 61 are partially taken up by the inner glass sheet. The inner plastic spacer sheet 42 undergoes fewer stresses, and the attachment of the intermediate wing 71 to the glazed element 2 is preserved.
    According to another embodiment not shown, the glazed element 2 could also comprise a single plastic interlayer sheet, which would then be in contact with the outer face of the intermediate flange 71 of the profile 6 and preferably the edge 71c of this wing 71.
    FIG. 7 illustrates a glazing unit 1 according to another embodiment of the invention, in which the glazed element 2 comprises, between the outer intermediate sheet 41 and the inner plastic interlayer sheet 42, a (third) intermediate interlayer sheet. made of plastic 43.
    The outer face 71a of the intermediate wing 71 is in contact with the inner face 41b of the outer intermediate sheet 41, the inner face 71b of the intermediate wing 71 is in contact with the outer face 42a of the inner spacer sheet 42, and the edge 71c of the intermediate flange 71 is in contact with the edge 43c of said intermediate intermediate sheet 43.
    Figure 8 illustrates a glazing unit 1 according to another embodiment of the invention, in particular a rear window, assembled on a vehicle bodywork part.
    In this example, the groove 61 of the profile 6 of the glazing 1 is not intended for clipping a cover piece 8, but is intended to form a flow channel, especially for runoff runoff.
    It has, in the example shown, a U-shaped cross section, but could have any other adapted section.
    In the example, the profile 6 bears on the body part 9.
    The bodywork part 9 is a bodywork bay having a recess near its distal edge, allowing the mounting of the glazing 1 in said bay.
    More particularly, the body part 9 has a main portion 91 and an end portion 92 (closer to the free edge of the bay than said main portion 91) recessed inwardly relative to said main portion 91 and connected to this one by a shoulder 93.
    In the example, the end portion 92 and the shoulder 93 form between them an angle close to a right angle.
    The functional part 60 of the profile 6 bears against the shoulder 93. The portion of the functional part 60 forming the distal duct 67 of the groove 61 and the bottom of the groove 61 are elastically deformed respectively against the shoulder 93 and the outer face of the end portion 92 of the bodywork part. Thus, the functional part 60 cooperates with the bodywork part 9 by complementarity of shape, ensuring the holding in position of said part and the sealing around the glazing 1. The glazed element 2 is fixed by gluing to said portion of end 92.
    Preferably, as illustrated in FIG. 8, the section 6 has a height such that after assembly the distal outer edge of the fixing portion 60 is in continuity with the outer face 91a of the main portion 91 of the bodywork 9.
    The present invention is applicable to any glazing and in particular to any vehicle glazing. It can be applied to any edge of this glazing: left, right, up or down and in particular to several of these edges at once, or all these edges at once.
