    SLIDING GLAZING SLIDING INNER EDGE
    The present invention relates to a glazing for a vehicle, and in particular for a motor vehicle, comprising a window as well as means for allowing the mobility of said window in translation relative to a door of said vehicle, said window being curved and laminated and comprising at at least one outer glass sheet, an inner glass sheet, as well as a plastic sheet located between said outer glass sheet and said inner glass sheet, each sheet having a peripheral edge.
    It is for example known from French patent application No. LR 2 525 677 a glazed opening arrangement with a laminated window whose inner glass sheet has an inner projection relative to the rest of the laminated window. This projection serves as a protruding guide means which is intended to slide in a hollow profile of the door during the translation of the glazing, so that the exterior face of the glazing is flush with the structure of the door when the glazing is closed. .
    It seems that this arrangement has never been implemented industrially.
    A plausible explanation is that this arrangement poses more problems than it solves: for a given opening, which must be closed by a sliding laminated glazing, the fact of providing an overhang for this laminated glazing poses more problems than provide laminated glazing of the same total thickness and without overhang for this same opening.
    Indeed, compared to a laminated glazing without overhang, when it is desired that the laminated glazing has an overhang, for the same opening, it is necessary to provide:
    both that the outer glass sheet is smaller than the laminated glazing without overhang, and at the same time that the inner glass sheet is larger than for the laminated glazing without protrusion.
    It is necessary to do these two operations because otherwise the laminated glazing with overhang cannot be properly maintained while maintaining the nominal dimensions of the opening:
    if it is chosen to provide only that the outer glass sheet is smaller than the laminated glazing without overhang, then the dimensions of the opening must be reduced, and if it is chosen to provide only that the inner glass sheet is larger than for laminated glazing without overhang, then it is necessary to increase the dimensions of the opening, and each of these two operations is to be avoided since each requires modifying the overall appearance of the vehicle.
    The two operations above which are essential to maintain an identical bay dimension are not carried out with the same extent; so that the laminated glazing is correctly maintained in the opening without modifying the dimensions of this opening, or the thicknesses of the constituents of the laminated glazing, it is necessary:
    that the outer glass sheet is only a little bit smaller than for laminated glazing without overhang (for example with an area reduced by 2%), and that the inner glass sheet is frankly larger than for laminated glazing without overhang (with in this example an area increased by 5%).
    Consequently, the decrease in the size of the outer glass sheet is not compensated by the increase in the size of the inner glass sheet: as the size of the inner glass sheet is more proportionally increased than the size of the outer glass sheet is not reduced, in the end, more glass is needed and the laminated glazing with overhang is made heavier.
    This increase in the weight of the glazing is harmful because it generates an increase in the consumption of the vehicle and because it is then necessary to design means of translation of the glazing that are more resistant.
    It is also known to produce a glazed opening arrangement with a laminated window with means for allowing the mobility of said window in translation relative to a door of said vehicle which is without a tall upright, or even without a lateral upright, or even without no side uprights.
    In these arrangements, in the closed position, the glazing is only slightly, if at all, retained at the top and laterally by the door but is retained in this position by means located directly on the body, in the body part adjacent to the door when the door is closed (part called "body bay").
    The prior art therefore knows European patent application No. EP 1 178 175 which relates to a system for positioning and assembling a very complex window comprising:
    an adapter element having a first extension in the extension of the glass and a second extension in the longitudinal direction of the glazing;
    a slider element guided in at least one rail secured to a door of the vehicle and driven by a drive device housed in said door; said slider being provided with a third extension in the longitudinal direction of the glass, at least one guide block secured to an element of the drive device and guided along a rail, as well as a wall vertical comprising a first vertical contact surface capable of cooperating with one of the faces of the first extension of the adapter element, the second extension of which cooperates with the third extension of the slider so as to allow a slight relative movement between the adapter and the cursor under the action of a longitudinal force applied to the glazing before its fixing;
    a confinement element comprising a contact surface; and a fixing means cooperating with the confinement element so as to block the first extension of the adapter between said first and second contact surfaces.
    Thus, when mounting the glazing in the door, the glazing can be adjusted in the vertical direction of the vehicle by the movement of the adapter between the slider and the locking element and in the longitudinal direction by the action from the third extension of the cursor to the second extension of the adapter.
    This solution is tedious to implement and generates a loss of time that is too great for the car manufacturer who seeks to have the car assembled in the minimum amount of time.
    It is also known from international patent application No. WO 01/98613, different solutions for assembling glass / glass holder and glass holder / drive mechanism.
    This document reveals in particular the possibility, when the glass holder is fixedly fixed to the glass, to make an adjustment of the geometry of the glass holder by removing material, in order to adapt the relative position of the glass holder relative to the drive mechanism (movable slider).
    This document also reveals the possibility of making up for differences in the shape of the glazing by modifying the positioning of the glass holder relative to the glass by using a glass holder having a slight play in the direction normal to the glazing. The glass holder is thus fixed to the glass using two glues, a slow glue and a quick glue, after relative displacement of one relative to the other in a suitable position.
    The object of the invention is to provide a mobile glazing structure in translation which is at the same time light, robust, efficient, easy to manufacture and easy to implement.
    Surprisingly, it has been discovered that it is possible to use a laminated pane with a thin inner pane, in order to lighten the glazing, to operate beforehand the chemical tempering of this inner sheet before to increase its mechanical resistance and to further provide at least one internal overhang for this fine chemical toughened inner window in order to lighten the window even more, while then making it possible to produce glazing flush with the door, or even with the adjacent bodywork (case of the door without amount).
    The present invention thus relates in its widest sense to vehicle glazing, comprising a window as well as means for allowing the mobility of said window in translation relative to a door of said vehicle which is upright in an upper part, said pane being curved and laminated and comprising at least one outer glass sheet, an inner glass sheet, as well as a plastic sheet situated between said outer glass sheet and said inner glass sheet, each sheet having a peripheral edge , remarkable in that said inner glass sheet is a glass sheet having undergone a chemical toughening operation and having a thickness of between 0.40 and 2.10 mm, or even between 0.40 and 1.80 mm, even between 0 , 40 and 1.60 mm and in that the edge of said inner glass sheet is located beyond the edge of said plastic sheet and the edge of the adite outer glass sheet on at least a part (that is to say on at least a part, or on several parts or on the whole) of the edge length of said inner glass sheet.
    The pane is a laminated pane in the sense that there is no gas space or empty space between the sheets which constitute the pane.
    The inner glass sheet has a thickness which is not greater than that of the outer glass sheet; it is at most equal, and preferably less, than that of the outer glass sheet.
    Said inner glass sheet may have a thickness smaller than the thickness of 2.10 mm and have a thickness of between 0.40 mm and 2.00 mm; it may in particular have a thickness of between 0.40 and 1.10 mm, or even between 0.40 and 0.70 mm. Its thickness must be sufficient to participate positively in the mechanical resistance and the rigidity of the glass but must not be too high so as not to increase the weight of the glass too much. Said inner glass sheet may for example have a thickness of 0.40 mm, or 0.55 mm, or 0.70 mm, or 1.10 mm, or 1.60 mm.
    In this document, for the ranges mentioned, the range limits are included in the ranges.
    The "edge" or "strand" designates the narrow side of a sheet, which is located substantially transversely between the two main faces of a sheet.
    The fact that the edge of said inner glass sheet is located beyond both the edge of said plastic sheet and the edge of said outer glass sheet along at least part of its length makes it possible to achieve an overhang of said outer glass sheet with respect to said plastic sheet and said glass sheet. This projection can be peripheral in the sense that it is present all around the periphery of the glass but it can also be partial and thus only be present along part of the periphery of the glass; it can also be present along several parts of the periphery of the glass; it may in particular not be present along the bottom edge of the glass.
    In a particular mode of application of the invention, the door of said vehicle is without jamb, at least in an upper part.
    The edge of said inner glass sheet preferably comprises a protective layer over at least part of the length of the edge of said inner glass sheet which extends beyond the edge of said plastic sheet and the edge of said outer glass sheet and preferably the edge of said inner glass sheet has a protective layer over the entire length of the edge of said inner glass sheet which is located beyond the edge of said sheet of material plastic and the edge of said outer glass sheet. Thus, the protective layer provides both protection for the inner glass sheet located below and both protection for handling in order to reduce the sharpness of the thin inner glass sheet.
    Said protective layer is a partial layer in the sense that it is not present on the whole of the exterior face or of the interior face of the interior glass sheet which carries it; when it is present on a part of an external and / or internal face of the internal glass sheet, the protective layer is present on only a very small part of this face (less than 1/10 th of the surface of this face), so as not to detrimentally reduce the clear view of the window.
    The edge of said inner glass sheet preferably comprises a protective layer which extends over a distance against an outer face of said inner glass sheet and / or against an inner face of said inner glass sheet, said distance being between 2.0 and 30.0 mm, or even between 3.0 and 20.0 mm and also being preferably constant on the outside of said inner glass sheet and / or constant on the inside of said glass sheet interior, to provide more effective protection.
    The edge of said inner glass sheet may have a protective layer which extends over a distance against an inner face of said inner glass sheet which is greater than a distance from the edge of said edge of said inner glass sheet in relation to the edge of said plastic sheet and edge of said outer glass sheet to provide more effective protection; This distance can be between 3.0 and 40.0 mm, or even between 4.0 and 30.0 mm, in particular when said distance over which the protective layer extends is between 2.0 and 30.0 respectively mm, or even between 3.0 and 20.0 mm.
    This protective layer can in particular come into contact with the edge of said plastic sheet, or even also with the edge of said inner glass sheet in order to provide even more effective protection.
    Said protective layer may be a varnish having a thickness of the order of 0.1 to 3.0 mm, which is easy to apply or may be a piece of plastic or metal or metal alloy. This part can be prefabricated and then wedged or glued to the external glass sheet after the glass has been manufactured (after laminating); when it is made of plastic, it can be manufactured in situ, for example by in situ extrusion or in situ encapsulation. Such a part makes the glazing more complex but can make it possible to achieve more effective protection.
    Preferably, the edge of said inner glass sheet extends beyond the edge of said plastic sheet and the edge of said outer glass sheet at least in the upper part of said glazing.
    In an independent and advantageous variant, the edge of said inner glass sheet extends beyond the edge of said plastic sheet and the edge of said outer glass sheet over only part of the length of the edge of said sheet of interior glass. The edge of said inner glass sheet may extend beyond the edge of said plastic sheet and the edge of said outer glass sheet over several parts of the length of the edge of said inner glass sheet but in this variant independent the edge of said inner glass sheet does not extend beyond the edge of said plastic sheet and the edge of said outer glass sheet over the entire length of the edge of said inner glass sheet.
    Thus, the glass is easier to manufacture because the part (s) of the edge of said inner glass sheet which does not extend beyond the edge of said plastic sheet and the edge of said outer glass sheet may (may) be such that the edge of said inner glass sheet is then in continuity with the edge of said plastic sheet and the edge of said outer glass sheet; this (these) part (s) can (can) then serve as reference part (s) for positioning the inner glass sheet with respect to the other two sheets during the manufacture of the glass (laminating).
    In addition, this (these) part (s) can (can) be located opposite the means allowing the mobility of said window in translation relative to the door of said vehicle (that is to say say the glass door (s)) in order to increase the mechanical strength of the glass at this point.
    In a specific variant, the edge of said inner glass sheet is in continuity with the edge of said outer glass sheet in a lower part of the glazing; for example, in a lower part which remains inside said door when said glazing is closed.
    In particular, the edge of said inner glass sheet may be in continuity with the edge of said outer glass sheet along the low glazing edge.
    The edge of said inner glass sheet extends beyond the edge of said outer glass sheet by forming a centripetal offset of preferably between 2.0 and 30.0 mm, or even between 3.0 and 20, 0 mm, said offset being preferably preferably constant along its length so that it is more discreet, aesthetically.
    In a particular variant, the edge of said inner glass sheet extends beyond the edge of said outer glass sheet, forming a centripetal offset along both the entire upper part and along only part of a single lateral edge, or even forming a centripetal offset along both the entire upper part and along only part of two lateral edges of said glazing.
    Advantageously, the present invention makes it possible to manufacture sliding glazing units fitted with glass holders which are both very resistant thanks to the laminated structure of the glass of which a sheet is chemically toughened, which are both very light thanks to the small thickness of this chemical toughened sheet and which are also easy to guide in translation thanks to the centripetal projection of the inner sheet relative to the rest of the laminated glass.
    The present invention was developed for glazing incorporated in doors having lateral uprights and an upright greater than the level of the glazing when the latter is raised (closed), but it can also be used for glazing incorporated in doors not presenting no side and upper uprights at the level of the glazing when it is reassembled.
    Advantageously above all, the present invention makes it possible to produce a glazing which, when closed, has an external face which is situated in the extension of the adjacent body part on the periphery (part of the door or direct part of the body if the door has no upright on the periphery of the glazing); which is known by the technical concept of "flush glazing", or "flush glazing" in English.
    The present invention will be better understood on reading the detailed description below of nonlimiting exemplary embodiments and the attached figures:
    • Figure 1 illustrates an external front view of a vehicle front glazing according to the invention, provided with two glass holders;
    • Figure 2 illustrates a vertical cross-sectional view of a window holder of Figure 1;
    • Figure 3 illustrates a side view of a front window glazing vehicle with two glass holders according to the invention during the fixing operation of a glass holder;
    • Figure 4 illustrates a partial view in vertical cross section of the glazing of Figure 1 between the two glass holders and without these glass holders, this glazing comprising an overhang in the upper part and no overhang in the lower part; and • Figure 5 illustrates a partial view in vertical cross section of a variant of Figure 4, the glazing comprising an overhang in the upper part and in the lower part.
    It should be noted that the proportions between the various elements shown in the figures are not strictly observed in order to facilitate reading.
    Figure 1 illustrates a right side window 1 of a vehicle according to the invention, considered to be seen from the outside of this vehicle.
    It is in particular a lateral glazing of a door of a motor vehicle which is movable between translation relative to this door substantially along the vertical between an open position in which the glazing is located wholly or almost entirely. all inside the door and a closed position in which the glazing closes a door opening.
    This glazing thus achieves in the closed position a vertical separation between an interior space I which is inside the vehicle and an exterior space E which is outside the vehicle.
    The concepts of "exterior" and "interior" are therefore considered in this document respectively with respect to this exterior space E and this interior space I.
    As it is a side glazing, this extends essentially along the axis generally called the "X axis" of the vehicle, which is the central longitudinal axis of advance of the vehicle equipped with the glazing according to the invention as lateral glazing on the right side of the vehicle and which corresponds to the horizontal axis in the plane of the sheet in FIG. L
    In the context of this document, the concept of "centripetal" and that of "centrifugal" is to be considered in the plane of the sheet in Figure 1, expressed relative to the center of the glazing, along the axes X and Z; the centrifugal direction is towards this center while the centripetal direction moves away from this center.
    In the embodiment of Figure 1, the glazing 1 is in one piece.
    In the illustrated embodiment, the glazing 1 comprises a pane 2 which is curved (that is to say non-flat) and laminated. However, for simplicity, it is considered in the drawings of Figures 1, 4 and 5 that the window 2 is flat.
    The pane 2 of the pane 1 is a laminated pane which comprises, from the outside to the inside, at least in this order: an outer glass sheet 3, an interlayer sheet of plastic 4 then an inner glass sheet 5 ; however, it is possible that at least one other sheet is interposed between the outer glass sheet 3 and the interlayer plastic sheet 4 or between the interlayer plastic sheet 4 and inner glass sheet 5.
    The outer glass sheet 3 has an outer face 30 which is oriented towards the outside E, an intermediate face 32 which is oriented towards the intermediate plastic sheet 4, and a peripheral edge 31 situated between these two faces.
    The inner glass sheet 5 has an intermediate face 50 which is oriented towards the intermediate plastic sheet 4, an inner face 52 which is oriented towards the inside I and a peripheral edge 51 located between these two faces.
    The plastic interlayer sheet 4 has an outer intermediate face 40 which is oriented towards the intermediate face 32 and which is here in contact with this intermediate face 32, an inner intermediate face 42 which is oriented towards the intermediate face 50 and which is here in contact with this intermediate face 50, as well as a peripheral edge 41 which is located between these two intermediate faces 40, 42.
    The outer glass sheet 3 is for example a glass sheet having undergone a thermal bending operation before the manufacture of the laminated pane 2 and having a thickness e 3 of between 1.20 and 4.50 mm, for example 2, 10 mm.
    The interlayer plastic sheet 4 is for example a polyvinyl butyral sheet (PVB) having a thickness Ci. Of between 0.50 and 1.50 mm, for example 0.78 mm. This plastic sheet 4 preferably has the same dimensions of length along the X axis and of height along the Z axis, as the outer glass sheet 3.
    The inner glass sheet 5 is a glass sheet having undergone a chemical toughening operation and having a thickness of between 0.40 and 2.10 mm, or even between 0.40 and 2.00 mm, or even between 0.40 and 1.80 mm, or even between 0.40 and 1.60 mm, for example 1.00 mm.
    Preferably the inner glass sheet 5 is not curved before the manufacture of the laminated window 2; it is this lamination which will give it its domed shape, following the shape of the outer glass sheet 3. This is made possible thanks to the thinness of the inner glass sheet.
    In the case where the window 2 comprises one or more other sheet (s) in addition to the three mentioned above, the inner glass sheet 5 which has undergone chemical toughening is the sheet of the laminated window which is the most the interior.
    The glazing 1 comprises, in addition to the glazing 2, along at least part of at least one bottom edge, means for allowing the mobility of the glazing 2 in translation relative to a door of the vehicle. These means comprise at least one and preferably at least two glass holders 6, 6 'having for example in cross section substantially an inverted h shape.
    FIG. 2 illustrates a detailed view of the window holder 6 of FIG. 1. This window holder 6 thus presents:
    a first part consisting of two parallel walls 63, 64 connected to their base and forming a longitudinal groove, that is to say forming in cross section a U-shape, and a second part consisting of a tail 65 extending opposite the parallel walls 63, 64 relative to the base connecting these walls.
    In the illustrated version, the assembly is carried out so that said parallel walls 63, 64 of said h-shape embed said window 2 in its lower part, the tail 65 then being substantially in the extension of the window 2.
    This h shape of the glass holder is particularly advantageous because it allows the transmission of forces between the glass holder and the glass over a large area corresponding to the sum of the interior surfaces of the parallel walls 63, 64; however, it is quite possible to use a simple plate, this plate having for example at least two parts: a first part for cooperation with the glass and a second part for cooperation with the drive mechanism (up / down ) from the window.
    In FIG. 2, the window 2 is curved and the parallel walls 63, 64 and the tail 65 are planar; however it is possible that the parallel walls 63, 64 and / or the tail 65 are curved. The tail 65 extends approximately from the half of the base connecting the parallel walls 63, 64, but it is also possible to position the tail 65 in the extension of one or the other of the parallel walls 63, 64.
    In FIG. 2 the tail 65 is not parallel to the walls 63, 64. The axis A illustrating the mean plane of the glazing 1 at its lower end when the latter is correctly positioned vis-à-vis the glass holder 6, the tail 65 is oriented at a non-zero angle with respect to the axis A and which is a function of the bending of the window 2.
    The tail 65 is intended to be connected to a motorized drive system not shown to allow the glazing 1 to go up and down in the vehicle door.
    The assembly of the glass holders 6, 6 ′ to the window 2 is carried out on a template allowing the control of tolerances on the window holder 6 / window 2 assembly.
    Before positioning and fixing the glass holders, the glass 2 is first of all correctly positioned (“focused”) in an assembly template 11, visible in FIG. 3, having a plurality of positioning stops, according to iso droop illustrated in Figure 1, in Zl, Z2, Yl, Z2, Y3 and X4.
    The point Y3 is preferably positioned on the line of a wiper seal7 illustrating the position of this low contact seal with the door when the glazing is closed.
    A matrix 12, illustrated in dotted lines, secured to the reference frame of the window 2 accommodates the shanks 65 of each window holder 6.
    Movable jaws lower 13 and upper 14 then grip the tail 65.
    Whatever the orientation of the glass holders 6 in the Y direction, the movable jaws 13, 14 lock the glass holders 6 without damaging the isostaticness described above.
    The glass holder (s) 6, 6 'is (or are) glued (s) using an adhesive, for example polyurethane, then “shod (s)” on the glass 2, that is ie it (s) is (or are) positioned (s) so that the pane is present in the U-shape, in abutment or not, inserting between said parallel walls 63, 64 and the pane 2 of the inserts 66 of plastic, such as for example polypropylene.
    In a variant, it is proposed to replace the positioning phase of inserts 66 added by an in-situ injection phase of adhesive material intended to form the inserts 66, made of thermoplastic hot-melt resin, for example based on polyamide.
    The injection of the inserts when the glass and the glass holders are correctly positioned relative to each other thus guarantees the position of the glass holder, whatever the curve of the glass.
    The hot-melt resin used has an elastic limit of approximately 5.5 N / mm and a breaking strength of 11 N / mm, calculated according to DIN 53455. It must be used at a temperature of approximately 220 ° C and at this temperature has a viscosity of the order of 5000 mPa.s, measured according to standard ASTM D 3236.
    When implementing this solution, it is also possible to use an additional adhesive to perfectly fix the insert to the parallel walls and to the glass.
    The inserts 66 added or manufactured in situ by injection thus serve to hold the window 2 relative to the parallel walls 63, 64 with respect to the lateral forces.
    The glass holders used are preferably made of aluminum alloy. For example, with an aluminum alloy of grade 6060 (AGS), a vertical pressing force of 30 to 50 tonnes is sufficient, i.e. related to the size of the glass holders, forces of approximately 150 GPa for glass holders in h of overall size of approximately 40x30 mm and of approximately 450 GPa for glass holders in h of overall dimension of approximately 60x60 mm.
    The glazed element 2 has an external face 20 which is produced by the external face 30 of the external glass sheet 3, an internal face 22 which is produced by the internal face 52 of the internal glass sheet 5 and a peripheral edge 21 located between these two faces, corresponding to the peripheral edge 31 of the outer glass sheet 3, the peripheral edge 41 of the plastic sheet 4 and the peripheral edge 51 of the inner glass sheet 5.
    According to the invention, the edge 51 of the inner glass sheet 5 is located beyond, in a centripetal direction, the edge 41 of said plastic sheet 4 and the edge 31 of the outer glass sheet 3 on at least part of the length of the edge 51 of the inner glass sheet 5, that is to say along at least part of the length of the edge 51 of the inner glass sheet 5.
    Thus, the inner glass sheet 5 has at least a height along the Z axis and / or a length along the X axis which is (are) greater than that (s) of the outer glass sheet 3.
    Preferably, the edge 51 of the inner glass sheet 5 is located beyond, in a centripetal direction, the edge 41 of the plastic sheet 4 and the edge 31 of the outer glass sheet 3 at least in the upper part glazing.
    The edge 51 of said inner glass sheet 5 is thus located beyond, in a centripetal direction, the edge 31 of said outer glass sheet 3 (and the edge 41 of the plastic sheet 4) by forming an offset 9 , or overflows, centripetal. This offset can be between 2.0 and 30.0 mm, or even between 3.0 and 20.0 mm, as for example here 2.85 mm; This offset 9 is preferably constant along its length.
    In Figure 1, the wiper seal 7 materializes the top of the door casing inside which the glazing 1 slides, when the glazing is closed. In this closed glazing position, all the part of the glazing which is located under this wiper seal 7 may not have any offset: in this part under the wiper seal 7, inside the casing of the door when the glazing is closed , it is possible that the edge 51 of the inner glass sheet 5 over one (or more) part (s) of its length, or even over its entire length, is in continuity with the edge 31 of the outer glass sheet 3.
    It is possible for example that the edge 51 of the inner glass sheet 5 is in the continuity of the edge 31 of the outer glass sheet 3 only where there are the means to allow the mobility of the window 2 in translation relative to a vehicle door.
    Above the wiper seal 7, the vehicle door may comprise at least one part without an upright. Thus, it is possible that the door:
    does not have a front side pillar and that it is the adjacent body part, otherwise called "pillar A" or "A-pillar" in English, which guides the glazing, and / or does not have a rear side pillar and it is the adjacent body part, otherwise called “the B-pillar” or “B-pillar” in English, which guides the glazing.
    The edge 51 of the inner glass sheet 5 preferably comprises a protective layer 8 over at least part of the length of the edge 51 of the inner glass sheet 5 which is located beyond, in a centripetal direction, the edge 41 of the plastic sheet 4 and the edge 31 of the outer glass sheet 3.
    More preferably, this protective layer 8 is present over the entire length of the edge 51 of the inner glass sheet 5 which is located beyond the edge 41 of the plastic sheet 4 and the edge 31 of the sheet exterior glass 3.
    The protective layer 8 further preferably extends over a distance d 8 , d 8 - against an outer face 50 of the inner glass sheet 5 and / or respectively against an inner face 52 of the inner glass sheet 5; this distance is preferably between 2.0 and 30.0 mm, or even between 3.0 and 20.0 mm and is also preferably constant on the outer face 50 of the inner glass sheet 5 and / or on the inner face 52 of the inner glass sheet 5.
    Thus, the protective layer preferably has an outer face 80 which is oriented towards the outside E, an inner face 82 which is oriented towards the inside I and a peripheral edge 81 situated between these two faces.
    The outer face 80 of the protective layer is preferably substantially parallel to the outer face 50 of the inner glass sheet 5 in the part which it covers, the inner face 82 of the protective layer is preferably substantially parallel to the inner face 52 of the inner glass sheet 5 in the part which it covers and the edge 81 of the protective layer is preferably substantially parallel to the edge 51 of the inner glass sheet 5 in the part which it covers.
    Here, the protective layer 8 extends over a distance d 8 against an outer face 50 of the inner glass sheet 5 which is identical to the height of the offset D. Thus, the protective layer comes into contact with the edge 41 of the plastic sheet and also provides protection for this edge.
    The purpose of the protective layer 8 is both to protect the edge (that is to say at least part of the overhang, or even the entire overhang, or even more than the overhang) of the inner glass sheet 5 so to prevent its degradation and at the same time to protect the users because of the potentially cutting edge of the edge of the interior glass sheet, with regard to its thickness and because of its nature (chemically toughened).
    Indeed, the chemical hardening can generate edges between the faces and the edge which can be sharp.
    The protective layer 8 can be a varnish having a thickness of the order of 0.1 to 3.0 mm, or even 0.2 to 2.0 mm, for example 0.5 mm; it can also be instead or in addition a piece of plastic or metal or metal alloy. It can be prefabricated and then wedged or glued to the outer glass sheet or made in situ when it is made of plastic, using for example the technology of in situ extrusion or encapsulation between two parts of molds closed on themselves or a hybrid technology of guided extrusion between two parts of mold not completely closed on themselves.
    The protective layer is here a plastic profile having a total thickness e 8 equal to at least twice the thickness es of the inner glass sheet 5.
    The protective layer is fixed to the window 2 before or after the fixing of the window holders 6, 6 ’but in any case before the fixing of the window 1 to the vehicle door. This fixing is preferably final in the sense that the protective layer cannot then be removed without damaging the glazing.
    The protective layer can also contribute to the aesthetics of the glazing by presenting an appropriate (identical) color with regard to the color of the vehicle body or by presenting a chrome appearance.
    In the embodiment illustrated in FIG. 1, the edge 51 of said inner glass sheet 5 is located beyond both the edge 41 of the plastic sheet 4 and both the edge 31 of the glass sheet outer 3 on only part of the length of the edge 51 of the inner glass sheet 5. In this case, the overhang is present along the side edges and the top edge of the glass, but is not present along from the bottom edge of the glass.
    Thus, as visible in FIG. 4, these three edges 31, 41, 51 are in continuity with one another along the axis Y in the lower part of the window, but are not in continuity with one of the other along the axis Y in the upper part of the window: the edge 51 of the inner glass sheet 5 is offset in the centripetal direction, that is to say:
    - along the Z axis at least along the top edge of the glass
    - And preferably further along the axis X at least along the lateral edge of the glass, or even more preferably along the two lateral edges of the glass.
    For example, the edge 51 of the inner glass sheet 5 can be shifted in the centripetal direction, along the top edge of the window and along the side edge of the window which is towards the rear of the vehicle, on the right on the Figure 1, otherwise known as "the B pillar" or "B-pillar" in English.
    Each sheet 3, 4, 5 has a periphery P3, P4, P5 peripheral: the periphery P5 of the inner glass sheet 5 extends beyond the periphery P 4 of the plastic sheet 4 and the periphery P3 of the outer glass sheet 3 over at least part of the length of the periphery P5 of the inner glass sheet 5.
    The periphery P5 of the inner glass sheet 5 is not in the continuity of the periphery P 3 of the outer glass sheet 3 in an upper part of the glazing which is present outside the walls of the door when the glazing is closed: the overhang is thus present along the entire periphery of the window which is visible from the outside when the window is closed.
    The periphery P5 of the internal glass sheet 5 is in the lateral continuity of the periphery P 3 of the external glass sheet 3 only in a lower part of the glazing: in the part of the glazing which remains inside said door when the glazing is closed, in order to participate in the reinforcement of the glass at this location in order to increase the reliability of the attachment of the glass holders to the glass.
    This periphery P5 of the inner glass sheet 5 which is offset in the centripetal direction relative to the peripheries P3 of the outer glass sheet 3 and P 4 of the plastic sheet 4 makes it possible to use this periphery P5 to guide the glazing 1 in corresponding profiles located vis-à-vis in the door opening when the door has uprights or in the opening of the bodywork which receives the door with respect to which the glazing can slide when the door has partial uprights glazing or does not include a glazing upright.
    In particular, this periphery can be embedded in a U-shaped profile provided in the upper part of the door or of the opening when the glazing is completely closed.
    Alternatively, the edge 51 of the inner glass sheet 5 extends beyond the edge 31 of the outer glass sheet 3 by forming the offset 9, or overhang, centripetal along both the entire an upper part and along the whole of an upper edge of the glazing and along only part of a single lateral edge, or even forming an offset 9, or overhang, centripetal along both of the whole an upper part and along only part of two lateral edges of said glazing.
    In an embodiment illustrated in FIG. 5, the edge of the inner glass sheet is located beyond the edge of the plastic sheet and the edge of the outer glass sheet over the entire length of the edge of the inner glass sheet.
    Thus, these three edges are not in continuity with each other, neither along the Y axis in the lower part of the glass, nor along the Y axis in the upper part of the glass, nor along the axis Y on the sides.
    In this embodiment, the centripetal projection is peripheral: it is present along the entire periphery of the window; the distance D is preferably constant all around the window 2.
    In the embodiment illustrated in FIG. 5, the protective layer 8 is also completely peripheral: it is present along the entire edge 51 of the inner glass sheet 5; it is however possible to interrupt the protective layer 8 in the zone, or in each zone, where the means are located to allow the mobility of the window 2 in translation relative to the vehicle door.
    Furthermore, in the embodiment illustrated in FIG. 5, the protective layer 8 extends over a distance d s - against the internal face 52 of the internal glass sheet 5 which is greater than the distance D from the edge of the edge 51 of the inner glass sheet 5 relative to the edge 41 of the plastic sheet 4 and to the edge 31 of the outer glass sheet 3. This distance d s - can be between 3.0 and 40.0 mm, or even between 4.0 and 30.0 mm, and may for example be 15.0 mm.
    The present invention is described in the foregoing by way of example. It is understood that a person skilled in the art is able to carry out different variants of the invention without going beyond the scope of the patent as defined by the claims.
