Glazing unit with two glass panes and a connection for assembling the glass panes

Description

[0001] The invention relates to a glazing for a means of transport, in particular a vehicle, and in particular a motor vehicle, comprising two contiguous panes and a seal, at least one of the panes being laminated.

[0002] Prior art discloses glazing units comprising a first pane and a second pane assembled side by side to ultimately form a single pane. Such an assembly is of interest when it is desired to obtain a glazing unit of complex shape. This may be, for example, glazing for a motor vehicle having a significant curvature along a first axis of curvature and a very slight curvature along a second axis, perpendicular to the first. Such glazing comprises, for example, both the windshield and a panoramic roof window of the vehicle, or both the windshield and fixed front side windows of the vehicle, or even both a roof window and a fixed rear window of the vehicle. The curving processes used in the glass industry make it possible to obtain a glazing unit in a single piece having a relatively slight curvature.For glazing with relatively significant curvature, it is preferable to assemble a first pane and a second pane using an assembly device in order to simplify production.

[0003] The prior art knows solutions for juxtaposing windows, and in particular for vehicles, for which a first window and a second window juxtaposed or contiguous to the first are assembled side by side using an assembly system.

[0004] International patent application No. WO 2006 / 064153 discloses an assembly system in which a portion of rigid profile is fixed to a first pane and has a projecting part to provide support for the second glazed element. In practice, this profile, due to its rigidity, is difficult to implement and is only suitable when the adjacent edges of the panes are completely straight.

[0005] International patent application No. WO 2018 / 178574 discloses another solution for such a glazing with a first pane and a second pane assembled side by side. It comprises two contiguous panes and two profiled seal bodies arranged opposite each other and each located in contact against a portion of the edge of one of said panes. The glazing further comprises one, or even two, flexible exterior coating(s) having an exterior face arranged in continuity with an exterior face of the pane. Thus, the glazing has a flush junction on its exterior face, consequently improving its aesthetics. The disadvantage of the configuration described in this document is that the interior face of the glazing has an unsightly protrusion due to the assembly means used. In addition, the assembly requires restrictive bonding operations which can cause sealing problems.

[0006] International patent application No. WO 2021 / 09356 discloses a glazing unit comprising a first pane and a second pane adjacent to each other with a single seal between the panes. The mechanical strength of this glazing unit could be improved.

[0007] An aim of the invention is to overcome the drawbacks of the prior art by proposing a glazing comprising two simple panes to assemble with each other and having improved aesthetics while having high mechanical strength.

[0008] The present invention is particularly suitable when the facing edges of the panes are curved.

[0009] To do this, the invention thus relates, in its broadest sense, to glazing for a means of transport, in particular a vehicle, according to claim 1.

[0010] This glazing comprises a first pane and a second contiguous pane, the second pane being laminated and comprising an outer glass sheet, an inner glass sheet and a plastic interlayer sheet arranged between said outer glass sheet and said inner glass sheet, said glazing having an outer face and an inner face, an edge of the interlayer sheet of said second pane being set back relative to an edge of the outer glass sheet of said second pane.

[0011] Said glazing comprises a seal arranged between said first pane and said second pane, adhering to an edge of said outer glass sheet of the second pane and an edge of said first pane and having an outer face and an inner face, the outer face of said glazing and the outer face of said seal being flush.

[0012] Said seal is in contact with an inner face of the outer glass sheet of said second pane.

[0013] By "flush" in the sense of the present invention, it is to be understood that at the junction between the first pane and the second pane, seen in cross-section, of the external space, there is no glazing element, and in particular no element of the seal, further outside than a flush line joining the external face of the first pane and the external face of the second pane.

[0014] In some variants, at the junction between the first pane and the second pane, seen in cross-section, of the interior space, there is no glazing element, and in particular no element of the seal, further inside than a flush line joining the inner face of the first pane and the inner face of the second pane.

[0015] The, or each, flush line is straight or curved; it is in continuity with the curvature of each face, meeting in the middle of the inter-glass space.

[0016] Thus, said seal has an outer face which forms the junction between an outer edge of said first pane and an outer edge of said second pane and furthermore, in certain variants, said seal has an inner face which forms the junction between an inner edge of said first pane and an inner edge of said second pane. The glazing is thus designed such that in the installed state, in the vehicle, no body pillar or any cover element is installed opposite the outer face of said seal and further outside, nor, in certain variants, opposite the inner face of said seal and further inside.

[0017] The outer face of said seal and, in certain variants, the inner face of said seal may be called "free" because they are visible respectively from a space outside the vehicle and from a space inside the vehicle. This freedom of the outer and inner faces of said seal is a given provided for from the design of the glazing; it is visible on the design plan of the vehicle and on the design plan of the vehicle glazing.

[0018] In some other variants, the glazing has a single bead of adhesive under the inner face of said seal. This bead of adhesive is visible on the vehicle design drawing and on the vehicle glazing design drawing. It is used to bond the glazing in a single strip along a body pillar or along an interior cover.

[0019] This seal is a simple connecting seal, ensuring the seal between the facing edges of the first and second panes; it is not a rigid support profile, as in international patent application No. WO 2006 / 064153; it is simpler to design, simpler to implement, and in particular can be curved along its length (facing the length of the edges of the first pane and the second pane).

[0020] Said seal is preferably made of a single material between its outer face and its inner face; this material may be multi-component in the sense that its chemical analysis may reveal the presence of several chemical components; however, the material analysis of the seal leads to the consideration that it is made of a single material.

[0021] Preferably, said seal comprises an insert; this insert being made of a different material, and preferably of a material with a higher Young's modulus than the material of the seal.

[0022] Advantageously, said insert is made of a metallic or plastic material, preferably reinforced with fibers and in particular glass or carbon fibers.

[0023] In one variant, said insert has a T shape, with the trunk of the T located between the first pane and the second pane.

[0024] Preferably, when the glazing has a single bead of glue and an insert, this bead of glue is located opposite the insert in order to increase the mechanical strength.

[0025] Preferably, the inner face of said glazing and the inner face of said seal are flush.

[0026] Preferably, said first pane is laminated and comprises an outer glass sheet, an inner glass sheet and a plastic interlayer sheet disposed between said outer glass sheet and said inner glass sheet; said outer glass sheet of said first pane has an interlayer face, said outer glass sheet of said second pane has an interlayer face.

[0027] Said seal is preferably in contact with an inner face of the outer glass sheet of said first laminated pane.

[0028] Said insert preferably has a face arranged opposite an intermediate face of the outer glass sheet of said second laminated pane, and preferably also opposite an intermediate face of the outer glass sheet of said first laminated pane.

[0029] Preferably, said glazing comprises at least one adhesion means arranged between said face of said insert and said intermediate faces.

[0030] Preferably, said adhesion means comprises a double-sided adhesive or a polymer such as polyurethane.

[0031] Preferably, said first pane is monolithic and has an inner face and said outer glass sheet of said second pane has an intermediate face, said insert having a face arranged opposite said inner face of the first pane and said intermediate face of said second pane.

[0032] Preferably, said first pane is monolithic and comprises an encapsulated seal comprising said insert.

[0033] When a pane of glass is laminated, the outermost sheet and the innermost sheet are preferably made of glass; when a pane of glass is monolithic, it may be made of glass or a plastic material, such as, for example, polycarbonate or polycarbonate-based.

[0034] The glazing according to the invention can be used to produce both the windshield and a panoramic roof window of a vehicle, or both the windshield and fixed front side windows of a vehicle, or even both a roof window and a fixed rear window of a vehicle, or even combinations of these possibilities.

[0035] Several embodiments of the present invention will be described below, by way of non-limiting examples, with reference to the appended figures in which: [ Fig.1 ] schematically illustrates a sectional view of a glazing unit comprising a first laminated pane and a second laminated pane, according to a first embodiment of the invention; [ Fig.2 ] schematically illustrates a sectional view of a glazing unit comprising a first monolithic pane and a second laminated pane, according to a second embodiment of the invention; [ Fig.3 ] schematically represents a sectional view of a glazing comprising a first laminated pane, a second laminated pane and an insert, according to a third embodiment of the invention; [ Fig.4 ] schematically represents a sectional view of a glazing comprising a first laminated pane, a second laminated pane and an insert, according to a fourth embodiment of the invention; [ Fig.5 ] schematically illustrates a sectional view of a glazing unit comprising a first laminated pane, a second laminated pane and an insert, according to a fifth embodiment of the invention; [ Fig.6 ] schematically represents a sectional view of a glazing comprising a first monolithic pane, a second laminated pane and an insert, according to a sixth embodiment of the invention; [ Fig.7 ] schematically represents a sectional view of a glazing comprising a first monolithic pane, a second laminated pane and an insert, according to a seventh embodiment of the invention; [ Fig.8 ] schematically represents a sectional view of the fourth embodiment of the invention with an insert with a mechanical connection system; and [ Fig.9 ] schematically represents a sectional view of the fourth embodiment of the invention with a single bead of glue.

[0036] The present invention is described by way of example in the context of an application as vehicle glazing. This glazing closes a bay by creating a separation between an exterior space E, which is exterior to the vehicle, and an interior space I, which is interior to the vehicle. The notions of “exterior” and “interior” are therefore considered in relation, respectively, to the exterior space E and the interior space I.

[0037] The present invention is described, by way of non-limiting example, by being applied to a windshield and panoramic roof glazing of a vehicle, and in particular of a motor vehicle. Thus, in the illustrative figures, the glazing is shown schematically, in vertical sectional views, in the state installed in a bodywork bay (not visible). The glazing comprises two panes arranged side by side or, more precisely, one in front of the other when the direction of travel of the vehicle is considered.

[0038] In the context of this document, the figures 1 à 7 show the central longitudinal axis of advance of the vehicle equipped with the glazing according to the invention as windshield and roof glazing, generally called the XX' axis of the vehicle.

[0039] In reference to the figure 1 , there is schematically illustrated in vertical cross-section a glazing 1 comprising a first pane 2 and a second pane 2', according to a first embodiment of the present invention. Each pane 2, 2' thus has an outer face 20, 20' oriented towards the outer space E, an inner face 22, 22' oriented towards the inner space I and a peripheral edge 21, 21', located between these two faces. Each of the two panes 2, 2' of the glazing 1 is, preferably, a laminated pane which comprises, from the outside to the inside, at least: an outer glass sheet 3, 3', an interlayer sheet of plastic material 4, 4' and an inner glass sheet 5, 5'; however, it is possible that at least one other sheet is interposed between the outer glass sheet 3, 3' and the interlayer sheet of plastic material 4, 4' or between the interlayer sheet of plastic material 4, 4' and the inner glass sheet 5, 5'.Straight edges 21, 21' are shown. Alternatively, the edges 21, 21' are rounded. Each outer glass sheet 3, 3' has an outer face 30, 30' which is oriented towards the outer space E and thus corresponding to the outer face 20, 20' of the window 2, 2', an intermediate face 32, 32' which is oriented towards the intermediate sheet of plastic material 4, 4', and an edge 31, 31' located between these two faces.

[0040] Each inner glass sheet 5, 5' has an interlayer face 50, 50' which is oriented towards the interlayer sheet of plastic material 4, 4', an inner face 52, 52' which is oriented towards the inner space I and thus corresponding to the inner face 22, 22' of the window 2, 2', and an edge 51, 51' located between these two faces.

[0041] Each interlayer sheet of plastic material 4, 4' has an outer interlayer face 40, 40' which is oriented towards the interlayer face 32, 32' and which is here in contact with this interlayer face 32, 32', an inner interlayer face 42, 42' which is oriented towards the interlayer face 50, 50' and which is here in contact with this interlayer face 50, 50', as well as an edge 41, 41' which is located between these two interlayer faces 40, 42 and 40', 42'.

[0042] The glazing is laminated glazing in the sense that there is no gas space or empty space between the sheets that constitute it in the exterior - interior transverse direction.

[0043] Each pane 2, 2' thus has an outer face produced by the outer face 30, 30' of the outer glass sheet 3, 3', an inner face produced by the inner face 52, 52' of the inner glass sheet 5, 5' and an edge located between these two faces, corresponding to the edge 31, 31' of the outer glass sheet 3, 3' and to the edge 51, 51' of the inner glass sheet 5, 5', these two edges (on the one hand 31, 51 and on the other hand 31', 51') being here in continuity with each other while being separated by a space corresponding to the thickness of the plastic sheet 4, 4'.

[0044] The edge 41' of the interlayer sheet 4' of the second laminated pane 2' is preferably set back relative to the edge 31' of the outer glass sheet 3' of the second pane 2'; the edge 41 of the interlayer sheet 4 of the first laminated pane 2 is preferably set back relative to the edge 31 of the outer glass sheet 3 of the first pane 2. This setback of the edge 41, 41' of the interlayer sheet 4, 4' relative to the edge 31, 31' of the outer glass sheet 3, 3' is preferably at least 1.0 mm; it may be between 1.0 mm and 20.0 mm, or even between 2.0 and 5.0 mm.

[0045] The adjacent pane 2' preferably has a thickness identical to the pane 2 in order to facilitate the positioning of one relative to the other during assembly and manufacture of the glazing 1.

[0046] The glazing 1 further comprises a seal 6. The seal 6 is made of plastic material and is produced after the manufacture of the panes 2, 2' so as to obtain their assembly in a contiguous manner to form the glazing 1. The material of the seal 6 may be a hot-melt adhesive, polyvinyl butyral, also known by the acronym PVB, ethylene vinyl acetate, also known by the acronym EVA or polyurethane, also known by the acronym PU. The seal 6 has an outer face 61, oriented towards the outer space E, and an inner face 62, oriented towards the inner space I. The outer face 61 is substantially flush with the outer face 20 of the pane 2 and with the outer face 20' of the pane 2'. Thus, the outer face 61 is substantially in continuity with the outer faces 20, 20' of two panes 2, 2'. The outer face 61 does not protrude further outwards than the outer faces 20, 20' of the two panes 2, 2'.This configuration is also called "flush" in English. The gap between the outer face 61 and the outer faces 20, 20' of two panes 2, 2' is between 0 and 0.5 mm. In addition, the inner face 62 is substantially flush with the inner face 22 of the pane 2 and with the inner face 22' of the pane 2'. Thus, the inner face 62 is substantially in continuity with the inner faces 22, 22' of two panes 2, 2'. The inner face 62 does not protrude further inside than the inner faces 22, 22' of the two panes 2, 2'. The gap between the inner face 62 and the inner faces 22, 22' of two panes 2, 2' is between 0 and 0.5 mm.

[0047] The glazing 1, according to the invention, has the advantage of having a more discreet junction than the glazings of the prior art. The aesthetics are therefore improved.

[0048] Furthermore, the assembly of two panes 2, 2' is simple to implement. It is also possible to form a glazing 1 having relatively complex shapes. In the first embodiment of the invention, the glazing 1 comprises two panes 2, 2', but the invention can be applied to a number of panes greater than two.

[0049] As explained below, the seal may comprise an insert and this insert may be made of a metallic or plastic material, preferably reinforced with fibers and in particular glass or carbon fibers. However, the seal may also be made of a single material between its outer face and its inner face; this material may be multi-component in the sense that its chemical analysis may reveal the presence of several chemical components; however, the material analysis of the seal leads to the consideration that it is made of a single material.

[0050] The seal can be made of translucent or even transparent material.

[0051] As further detailed below, the glazing may comprise at least one adhesion means arranged between one face of the insert and intermediate faces of the interior panes and / or interior faces of interior panes. This adhesion means may comprise a double-sided adhesive or a polymer such as polyurethane.

[0052] Thanks to the removal of the edge 41' of the interlayer sheet 4' of the second laminated pane 2', the seal 6 is in contact with the inner face 32' of the outer glass sheet 3' of the second pane 2'; the seal 6 thus penetrates into the volume created thanks to the removal and the mechanical strength of the seal, and thus of the glazing, is reinforced.

[0053] Furthermore, the edge 41' of the interlayer sheet 4' of the second laminated pane 2' is preferably set back relative to the edge 51' of the inner glass sheet 5' of the second pane 2'; thus, the seal 6 is in contact with the interlayer face 50' of the inner glass sheet 5' of the second pane 2' and the mechanical strength of the seal, and thus of the glazing, is reinforced.

[0054] Thanks to the withdrawal of the edge 41 of the interlayer sheet 4 of the first laminated pane 2, the seal 6 is in contact with the inner face 32 of the outer glass sheet 3 of the second pane 2; the seal 6 thus penetrates into the volume created thanks to the withdrawal and the mechanical strength of the seal, and thus of the glazing, is reinforced.

[0055] Furthermore, the edge 41 of the interlayer sheet 4 of the first laminated pane 2 is preferably set back relative to the edge 51 of the inner glass sheet 5 of the first pane 2; thus, the seal 6 is in contact with the interlayer face 50 of the inner glass sheet 5 of the first pane 2 and the mechanical strength of the seal, and thus of the glazing, is reinforced.

[0056] The withdrawal of the edge 41, 41' of the interlayer sheet 4, 4' relative to the edge 51, 51' of the inner glass sheet 5, 5' is preferably at least 1.0 mm; it may be between 1.0 mm and 20.0 mm, or even between 2.0 and 5.0 mm. In a particular configuration, the withdrawal of the edge 41, 41' of the interlayer sheet 4, 4' relative to the edge 31, 31' is identical to the withdrawal of the edge 41, 41' of the interlayer sheet 4, 4' relative to the edge 51, 51' of the inner glass sheet 5, 5'.

[0057] In reference to the figure 2 , a glazing 201 is schematically illustrated comprising a first pane 202 and a second pane 202', according to a second embodiment of the present invention. The first pane 202 is a monolithic glass sheet comprising an outer face 220 oriented towards the outer space E, an inner face 222 towards the inner space I and a peripheral edge 221 located between these two faces. The second pane 202' is a laminated pane comprising an outer face 220' oriented towards the outer space E, an inner face 222' towards the inner space I and a peripheral edge 221' located between these two faces.The second pane 202' is a laminated pane and comprises, from the outside to the inside, at least: an outer glass sheet 203', an interlayer sheet of plastic material 204' and an inner glass sheet 205'; however, it is possible for at least one other sheet to be interposed between the outer glass sheet 203' and the interlayer sheet of plastic material 204' or between the interlayer sheet of plastic material 204' and the inner glass sheet 205'. Straight edges 221, 221' are shown. Alternatively, the edges 221, 221' are rounded. The outer glass sheet 203' has an outer face 230' which is oriented towards the outer space E and thus corresponding to the outer face 220' of the window 202', an intermediate face 232' which is oriented towards the intermediate sheet of plastic material 204', and an edge 231' located between these two faces.

[0058] The inner glass sheet 205' has an interlayer face 250' which is oriented towards the interlayer sheet of plastic material 204', an inner face 252' which is oriented towards the inner space I and thus corresponding to the inner face 222' of the window 202', and an edge 251' located between these two faces.

[0059] The plastic interlayer sheet 204' has an outer interlayer face 240' which is oriented towards the interlayer face 232' and which is here in contact with this interlayer face 232', an inner interlayer face 242' which is oriented towards the interlayer face 250' and which is here in contact with this interlayer face 250', as well as an edge 241' which is located between these two interlayer faces 240', 242'.

[0060] A window is said to be "laminated" in the sense that there is no gaseous space or empty space between the at least three sheets that constitute it in the exterior - interior transverse direction.

[0061] The window 202' thus has an outer face produced by the outer face 230' of the outer glass sheet 203', an inner face produced by the inner face 252' of the inner glass sheet 205' and an edge located between these two faces, corresponding to the edge 231' of the outer glass sheet 203' and to the edge 251' of the inner glass sheet 205', these two edges being here in continuity with each other while being separated by a space corresponding to the thickness of the plastic sheet 204'.

[0062] The glazing 201 further comprises a seal 206. The seal 206 is made of plastic material and is produced after the manufacture of the panes 202, 202' so as to obtain their assembly in a contiguous manner to form the glazing 201. The material of the seal 206 may be a hot-melt adhesive, polyvinyl butyral, also known by the acronym PVB, ethylene vinyl acetate, also known by the acronym EVA or polyurethane, also known by the acronym PU. The seal 206 has an outer face 261, oriented towards the outer space E, and an inner face 262, oriented towards the inner space I. The outer face 261 is substantially flush with the outer face 220 of the pane 202 and with the outer face 220' of the pane 202'. Thus, the outer face 261 is substantially in continuity with the outer faces 220, 220' of two windows 202, 202'.The outer face 261 does not protrude further outward than the outer faces 220, 220' of the two panes 202, 202'. The gap between the outer face 261 and the outer faces 220, 220' of two panes 202, 202' is between 0 and 0.5 mm.

[0063] The inner face 262 of the seal 206 has an inclination such that it is substantially in continuity with the inner faces 222, 222' of two panes 202, 202'. The seal 206, due to the inclination of the inner face 262, makes it possible to connect the inner face 222 of the first pane 202 and the inner face 222' of the second pane 202'. Although the thicknesses of the first and second panes 202, 202' are different, the seal 206 has the advantage of ensuring continuity between their respective inner faces 222, 222'. The glazing 201 has the advantage of presenting a more aesthetic junction between a monolithic pane and a laminated pane.

[0064] On this figure 2 , as only the second pane 202' is laminated, only the edge 241' of the interlayer sheet is set back relative to the edge 231' of the outer glass sheet 3' of the second pane 202'; this edge 241' of the interlayer sheet is, preferably, further set back relative to the edge 251' of the inner glass sheet; the seal 206 thus penetrates into the volume created by the setback and the mechanical strength of the seal, and thus of the glazing, is reinforced.

[0065] In a particular configuration, the withdrawal of the edge 41' of the interlayer sheet 4' relative to the edge 31' is identical to the withdrawal of the edge 41' of the interlayer sheet 4' relative to the edge 51' of the inner glass sheet 5'.

[0066] In reference to the figure 3 , a glazing 301 is schematically illustrated according to a third embodiment of the present invention. This third embodiment is an alternative to the first embodiment of the invention. Consequently, in order to avoid a redundant description, the elements and references common to the first embodiment are not described again in the description of this third embodiment. Thus, the glazing 301 further comprises, compared to the glazing 1 described previously, an insert 368. The insert 368 has a T-shape, in a cross-sectional view, and comprises a central portion 369, a first wing 370 and a second wing 371. The central portion 369 has a parallelepiped shape and has an axis AA' oriented perpendicularly to the axis X-X'. Preferably, the axis AA' is arranged substantially in the middle of the seal 6. In an alternative, the insert 368 has a curved shape.The first and second wings 370, 371 also have a parallelepiped shape and further have an axis BB' oriented perpendicularly to the axis A-A'. The insert 368 is, for example, made of a metallic material, such as aluminum, stainless steel, or a plastic material, such as polyethylene, possibly reinforced with carbon or glass fibers. The insert 368 makes it possible to increase the rigidity and strength of the joint 6.

[0067] In reference to the figure 4 , a glazing unit 401 is schematically illustrated comprising a first pane 402 and a second pane 402', according to a fourth embodiment of the present invention. Each pane 402, 402' is laminated and has an outer face 420, 420' facing the outer space E, an inner face 422, 422' facing the inner space I. Each of the two panes 402, 402' of the glazing unit 401 is, preferably, a laminated pane which comprises, from the outside to the inside, at least: an outer glass sheet 403, 403', an interlayer sheet of plastic material 404, 404' and an inner glass sheet 405, 405'; however, it is possible that at least one other sheet is interposed between the outer glass sheet 403, 403' and the plastic interlayer sheet 404, 404' or between the plastic interlayer sheet 404, 404' and the inner glass sheet 405, 405'.Each outer glass sheet 403, 403' has an outer face 430, 430' which is oriented towards the outer space E and thus corresponding to the outer face 420, 420' of the window 402, 402', an intermediate face 432, 432' which is oriented towards the intermediate sheet of plastic material 404, 404', and an edge 431, 431' located between these two faces.

[0068] Each inner glass sheet 405, 405' has an interlayer face 450, 450' which is oriented towards the interlayer sheet of plastic material 404, 404', an inner face 452, 452' which is oriented towards the inner space I and thus corresponding to the inner face 422, 422' of the window 402, 402', and an edge 451, 451' located between these two faces.

[0069] Each plastic interlayer sheet 404, 404' has an outer interlayer face 440, 440' which is oriented towards the interlayer face 432, 432' and which is here in contact with this interlayer face 432, 432', an inner interlayer face 442, 442' which is oriented towards the interlayer face 450, 450' and which is here in contact with this interlayer face 450, 450', as well as an edge 441, 441' which is located between these two interlayer faces 440, 442 and 440', 442'.

[0070] Each pane 402, 402' thus has an outer face produced by the outer face 430, 430' of the outer glass sheet 403, 403', an inner face produced by the inner face 452, 452' of the inner glass sheet 405, 405' and an edge located between these two faces, corresponding to the edge 431, 431' of the outer glass sheet 403, 403' and to the edge 451, 451' of the inner glass sheet 405, 405', these two edges (on the one hand 431, 451 and on the other hand 431', 451') being here in continuity with each other while being separated by a space corresponding to the thickness of the plastic sheet 404, 404'.

[0071] The glazing 401 further comprises a seal 406 having the same characteristics as those described in the first embodiment of the invention. The seal 406 has an outer face 461, oriented towards the outer space E, and an inner face 462, oriented towards the inner space I. The outer face 461 is substantially flush with the outer face 420 of the pane 402 and with the outer face 420' of the pane 402'. Thus, the outer face 461 is substantially in continuity with the outer faces 420, 420' of two panes 402, 402'. The outer face 461 does not protrude further outward than the outer faces 420, 420' of the two panes 402, 402'. The gap between the outer face 461 and the outer faces 420, 420' of two panes 402, 402' is between 0 and 0.5 mm. Furthermore, the inner face 462 is substantially flush with the inner face 422 of the pane 402 and with the inner face 422' of the pane 402'.Thus, the inner face 462 is substantially in continuity with the inner faces 422, 422' of two panes 402, 402'. The inner face 462 does not protrude further inward than the inner faces 422, 422' of the two panes 402, 402'. The gap between the inner face 462 and the inner faces 422, 422' of two panes 402, 402' is between 0 and 0.5 mm.

[0072] The edges 441, 451 of the interlayer sheet 404 and of the inner glass sheet 405 of the first pane 402 are set back relative to the edge 431 of the outer glass sheet 403 of the first pane 402. The edges 441', 451' of the interlayer sheet 404' and of the inner glass sheet 405' of the second pane 402' are set back relative to the edge 431' of the outer glass sheet 403' of the second pane 402'.

[0073] The withdrawal of the edges 441, 451 on the one hand and of the edges 441', 451' on the other hand are preferably each between 5.0 and 20.0 mm; for example 10.0 mm.

[0074] These recesses allow the seal 406 to be in contact with the inner faces 432, 432' of the outer glass sheets 403, 403'. The seal 406 further comprises an insert 468 having a parallelepiped shape. Preferably, the thickness of the insert 468 is between 0.3 times and 1 time the thickness of the inner glass sheets 405, 405'. The insert 468 has an outer face 469 and an inner face 470. The seal 406 further comprises a first layer of adhesive 471 arranged between the outer face 469 of the insert 468 and the inner face 432 of the outer glass sheet 403 of the first pane 402. The seal 406 also comprises a second layer of adhesive 471' arranged between the outer face 469 of the insert 468 and the inner face 432' of the outer glass sheet 403' of the second pane 402'. For example, the layer of adhesive comprises polyurethane (PU).This configuration makes it possible to reinforce the rigidity and mechanical resistance of the 406 joint.

[0075] There figure 8 further illustrates that it is possible to provide that the insert 468 comprises a mechanical connection system to allow the attachment and removal of an accessory such as a finishing part, a trim, a spoiler or an electronic part such as a signal light part or a vehicle guidance system part (e.g. LIDAR).

[0076] There figure 9 further illustrates that it is possible to provide that the glazing according to the invention comprises a single bead of glue 100 under the inner face 62 of the seal 6, 206, 406, 606, 706. This allows a gain in the dimensioning of an internal cross member and consequently a reduction in the weight of the vehicle equipped with the glazing.

[0077] Furthermore, with a single bead of glue 100, it is then possible to pass one or more electrical connectors 110, 110' from the interior space to the glazing on each side of the single bead of glue 100 without having to cross it, and therefore, without risk of degrading its qualities.

[0078] There figure 5 illustrates a fifth embodiment of the invention representing an alternative to the fourth embodiment. Consequently, in order to avoid a redundant description, the elements and references common to the fourth embodiment are not described again in the description of this fifth embodiment. Thus, the glazing 501 comprises a first double-sided adhesive 571 disposed between the outer face 469 of the insert 468 and the inner face 432 of the outer glass sheet 403 of the first pane 402, which is ultimately located inside the seal 406. The glazing 501 also comprises a second double-sided adhesive 571' disposed between the outer face 469 of the insert 468 and the inner face 432' of the outer glass sheet 403' of the second pane 402', which is also ultimately located inside the seal 406.For example, the double-sided adhesive used comprises a polyethylene support coated with acrylic; it can also be, for example, a layer of polyurethane-based glue. This configuration makes it possible to reinforce the rigidity and mechanical resistance of the seal 406.

[0079] Now referring to the figure 6 , a glazing 606 is schematically illustrated according to a sixth embodiment of the invention. The glazing 606 comprises a first pane 602 and a second pane 602'. The first pane 602 is a monolithic glass sheet comprising an outer face 620 oriented towards the outer space E, an inner face 622 towards the inner space I and a peripheral edge 621 located between these two faces. The second pane 602' is a laminated pane comprising an outer face 620' oriented towards the outer space E, an inner face 622' towards the inner space I.The second pane 602' comprises, from the outside to the inside, at least: an outer glass sheet 603', an interlayer sheet of plastic material 604' and an inner glass sheet 605'; however, it is possible for at least one other sheet to be interposed between the outer glass sheet 603' and the interlayer sheet of plastic material 604' or between the interlayer sheet of plastic material 604' and the inner glass sheet 605'. A straight edge 621 is shown. Alternatively, the edge 221 is rounded. The outer glass sheet 603' has an outer face 630' which is oriented towards the outer space E and thus corresponding to the outer face 620' of the pane 602', an interlayer face 632' which is oriented towards the interlayer sheet of plastic material 604', and an edge 631' located between these two faces. This configuration of the . figure 6 is particularly suitable for a connection between a laminated pane and a monolithic pane made of plastic or thermally tempered glass.

[0080] The inner glass sheet 605' has an interlayer face 650' which is oriented towards the interlayer sheet of plastic material 604', an inner face 652' which is oriented towards the inner space I and thus corresponding to the inner face 622' of the window 602', and an edge 651' located between these two faces.

[0081] The plastic interlayer sheet 604' has an outer interlayer face 640' which is oriented towards the interlayer face 632' and which is here in contact with this interlayer face 632', an inner interlayer face 642' which is oriented towards the interlayer face 650' and which is here in contact with this interlayer face 650', as well as an edge 641' which is located between these two interlayer faces 640', 642'.

[0082] The window 602' thus has an outer face produced by the outer face 630' of the outer glass sheet 603', an inner face produced by the inner face 652' of the inner glass sheet 605' and an edge located between these two faces, corresponding to the edge 631' of the outer glass sheet 603' and to the edge 651' of the inner glass sheet 605', these two edges being here in continuity with each other while being separated by a space corresponding to the thickness of the plastic sheet 604'.

[0083] The glazing 601 further comprises a seal 606 having the characteristics described in the second embodiment. Thus, these characteristics are not described again for the description of this sixth embodiment. The edges 641', ​​651' of the interlayer sheet 604' and of the inner glass sheet 605' of the second pane 602' are set back relative to the edge 631' of the outer glass sheet 603' of the second pane 602'. These setbacks allow the seal 606 to be in contact with the inner face 632' of the outer glass sheet 603'. The inner face 662 of the seal 606 has an inclination and comprises an insert 668 having the characteristics of the insert described in the fifth embodiment. Thus, the glazing 601 comprises a first double-sided adhesive 671 arranged between the outer face 669 of the insert 668 and the inner face 622 of the first pane 602, which is ultimately located inside the seal 406.The glazing 601 also includes a second double-sided adhesive 671' disposed between the outer face 669 of the insert 668 and the inner face 632' of the outer glass sheet 603' of the second pane 602' which is ultimately located inside the seal 406.

[0084] Referring now to the figure 7 , a glazing 701 according to a seventh embodiment of the invention is schematically illustrated. The glazing 701 comprises a first pane 702 and a second pane 702'. The first pane 702 is a monolithic glass sheet comprising an outer face 720 oriented towards the outer space E, an inner face 722 towards the inner space I and a peripheral edge 721 located between these two faces. The second pane 702' is a laminated pane comprising an outer face 720' oriented towards the outer space E, an inner face 722' towards the inner space I and a peripheral edge 721' located between these two faces.The second pane 702' comprises, from the outside to the inside, at least: an outer glass sheet 703', an interlayer sheet of plastic material 704' and an inner glass sheet 705'; however, it is possible for at least one other sheet to be interposed between the outer glass sheet 703' and the interlayer sheet of plastic material 704' or between the interlayer sheet of plastic material 704' and the inner glass sheet 705'. Straight edges 721, 721' are shown. Alternatively, the edges 721, 721' are rounded. The outer glass sheet 703' has an outer face 730' which is oriented towards the outer space E and thus corresponding to the outer face 720' of the window 702', an intermediate face 732' which is oriented towards the intermediate sheet of plastic material 704', and an edge 731' located between these two faces. This configuration of the . figure 7is particularly suitable for a connection between a laminated pane and a monolithic pane of plastic or thermally tempered glass which has an encapsulated seal.

[0085] The inner glass sheet 705' has an interlayer face 750' which is oriented towards the interlayer sheet of plastic material 704', an inner face 752' which is oriented towards the inner space I and thus corresponding to the inner face 722' of the window 702', and an edge 751' located between these two faces.

[0086] The plastic interlayer sheet 704' has an outer interlayer face 740' which is oriented towards the interlayer face 732' and which is here in contact with this interlayer face 732', an inner interlayer face 742' which is oriented towards the interlayer face 750' and which is here in contact with this interlayer face 750', as well as an edge 741' which is located between these two interlayer faces 740', 742'.

[0087] The window 702' thus has an outer face produced by the outer face 730' of the outer glass sheet 703', an inner face produced by the inner face 752' of the inner glass sheet 705' and an edge located between these two faces, corresponding to the edge 731' of the outer glass sheet 703' and to the edge 751' of the inner glass sheet 705', these two edges being here in continuity with each other while being separated by a space corresponding to the thickness of the plastic sheet 704'.

[0088] The glazing 701 further comprises a seal 706 having the characteristics described in the second embodiment. Thus, these characteristics are not described again. The seal 706 has an outer face 761, an inner face 762 and comprises an insert 768. The glazing 701 further comprises an encapsulated seal 780 in contact with the first pane 702. The encapsulated seal 780 is arranged around the periphery of the first pane 702 and ensures sealing, for example, with the body of the vehicle. The insert 768 is integrated both with the seal 706 and with the encapsulated seal 780. The encapsulated seal 780 has an outer face 781 and an inner face 782. The outer face 761 of the seal 706 is substantially flush with the outer face 720 of the window 702, with the outer face 720' of the window 702' and with the outer face 781 of the encapsulated seal 780.Thus, the outer face 761 is substantially in continuity with the outer faces 720, 720' of two panes 702, 702' as well as with the outer face 781 of the encapsulated seal 780. The inner face 762 of the seal 706 is in continuity with the inner face 782 of the encapsulated seal 780 and the inner face 722' of the inner glass sheet 705'.
