- the present invention is based on the idea of very quickly creating a mechanical wedging of the window holder next to the U-shaped part, and preferably on each side of the U-shaped part, when the window holder is positioned in the appropriate position. vis-à-vis the window, this prior mechanical wedging allowing the implementation, slowly, of the chemical fixing of the window holder to the window by the usual glue.
- the present invention further intends to provide a process for the mass production of glazing with a single adhesive material which is faster than previously, in particular a process for which it is not necessary to wait for polymerization, drying or curing. full of glue to remove the glass from the reference frame which is used to fix the means allowing the mobility of the glass.
- the present invention intends to propose a glazing whose means allowing its mobility are fixed in a more precise way and which moreover has cost less to manufacture, because manufactured more quickly.
- the present invention thus relates in its broadest sense to a method of manufacturing a vehicle glazing according to claim 1.
- This glazing comprises a pane having an outer face, an inner face and a peripheral edge, as well as means to allow mobility of said window in vertical translation relative to a door of said vehicle, said fixing means being located in at least one fixing zone and comprising a window holder having a U-shaped part.

- said quick hardening plastic material is applied after the application of said glue.
- said fast hardening plastic material is applied at the same time as said glue, in the sense that the two applications have a common duration, in order to reduce the manufacturing cycle time (it is possible that one application starts after the start of the other and/or that one application ends after the end of the other, but they have a duration in common).
- the application of the glue through the wall of said window holder is carried out opposite the edge of said window.
- said glue is in the form of a layer, located between the window and the U-shaped part of the window holder.
- Said fast-curing plastic material preferably hardens in a maximum of 60 seconds.
- it is not a layer of continuous thickness but a mass of material, of fluctuating thickness.
- the glazing is removed from the reference frame only after said fast-hardening plastic has hardened so that the fixing is reliable.
- Said rapid-hardening plastic material is preferably a thermoplastic or thermosetting material and preferably has, in the hardened state, a hardness of at least 60 Shore A.
- Said quick-hardening plastic material preferably, is not present inside said U-shaped part of the window holder; it is preferably applied only:
- a lateral extension is thus, preferably, a part of the window holder which is opposite the window, which is distinct from a central U-shaped part, and which does not include glue.
- a junction part which is not U-shaped, such as for example one or two arms or one or two connection plate(s), between a central U-shaped part and a lateral extension.
- Said glue is preferably present after application only inside said U-shaped part.
- each lateral extension is linked to said U-shaped part by a link arm or by a link plate so that the glue overflows near or in contact with this link arm or this link plate .

- At least one application of the fast-hardening plastic material, and preferably each application of the fast-hardening plastic material, is preferably carried out opposite the edge of said pane.
- Said applications are preferably carried out in said reference frame: preferably, without moving the window between the injections, in order to allow the most secure fixing fast and as reliable as possible.
- said window is thus preferably removed from the reference frame after the application of all of said fast-hardening plastic material and all of said glue.
- Said rapid hardening plastic material is preferably in contact with the exterior face, the interior face and the edge of the said pane.
- Said glue is preferably in contact with the outer face, the inner face and the edge of said window.
- Said pane can be monolithic, completely laminated or partially laminated.
- Said pane may be partially laminated, with in a laminated part at least one outer glass sheet, one inner glass sheet, as well as a sheet of adhesive material located between said outer glass sheet and said inner glass sheet, said attachment zone, and preferably each attachment zone, being non-laminated.
- the pane is preferably a partially laminated pane in the sense that there is no gas space or empty space between the sheets which constitute the pane.
- the thickness of said outer glass sheet is between 2.85 mm and 4.85 mm.

- At least one, and preferably each, application of the fast-curing plastic material is made through said lateral extension through a hole.
- Said means for allowing the mobility of said window may comprise, within the meaning of the present invention, a window holder or attachment gutter (“holder” in English), or rails, or slides.
- Said means for allowing the mobility of said pane preferably, do not comprise a hole partially or totally passing through said pane (that is to say over part of the thickness of an element composing it or the whole of the thickness of this element or over part of the thickness of the window comprising several elements at this location, or even over the entire thickness of the window).
- the present invention also relates to vehicle glazing, in particular obtained by implementing the manufacturing method according to the invention, said glazing comprising a pane having an outer face, an inner face and a peripheral edge, as well as fixing means to allow the mobility of said window in vertical translation relative to a door of said vehicle, said fixing means being located in at least one fixing zone and comprising a window holder having a U-shaped part, said glazing being remarkable in that:
- an adhesive is present opposite an edge of said window such that said adhesive is positioned in said U-shaped part, between at least said window and said window holder, and

- said lateral extension is in the form of a lateral U, preferably of identical section to said central U-shaped part, encasing an edge of said window; said lateral U-shape encases an edge of said pane preferably at a distance from the faces and the edge of the pane but a wall of the lateral U-shape may optionally be in contact with a face or the edge of said pane, depending on the shape of the window.
- At least one, and more preferably each, lateral extension is linked to said U-shaped part by a connecting arm (relatively thin) or by a connecting plate (relatively high); this link preferably extends further from the window than the side extension if the side extension is in contact with said window, or extends further from the window at the same distance as the side extension if the the lateral extension is at a distance from said window.
- edge designates the narrow side of a sheet, which is located substantially transversely between the two main faces of a sheet.
- the method of manufacturing the glazing according to the invention is easier to implement because the window can be maintained in the reference frame in any position, and in particular in the most suitable position vis-à-vis screw of gravity while being faster to implement since it is not necessary to wait for the polymerization or the drying or the complete hardening of the glue to remove the glazing from the reference frame; just wait for the fast-curing plastic to harden.
- the present invention has been developed for glazing incorporated in doors not having side uprights or an amount higher than the level of the glazing when the latter is raised (closed).
- the present invention makes it possible to produce glazing with means allowing its mobility which are fixed to the window with very high precision, in particular along the Y axis, and very high reliability, while being light.

- FIG. 12 illustrates a partial top view of the bonding of the window holder of [Fig. 11] with the addition of a fast hardening plastic material.
- FIG. 1 illustrates a window 1, left side of a vehicle, according to one embodiment of the invention, considered as being seen from inside this vehicle. It is in particular a side window of a door of a motor vehicle (not visible in [Fig. 1]) which is movable between translation with respect to this door substantially along the vertical between an open position in which the glazing is situated entirely or almost entirely inside the door and a closed position in which the glazing closes a bay of the door.
- 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 mobility of the glazing relative to the door is essentially vertical in the sense that this mobility takes place along the Z axis, with possibly a small component along the transverse axis Y not shown in [Fig. 1]
- the glazing 1 is in one piece.
- the glazing 1 comprises a pane 2 which is monolithic and curved (that is to say not flat): it consists of a single sheet of glass or plastic material, preferably glass.
- the pane 2 could be more complex: curved and laminated, or even curved and partially laminated.
- the [Lig. 1] shows that the window 2 has an outer face 20 which is oriented towards the outer space E, an inner face 22 which is oriented towards the inner space I and a peripheral edge 21 located between these two faces.
- the pane 2 has a first side edge 23, a second side edge 24, a top edge 25 and a bottom edge 26.
- the first side edge 23 and the second side edge 24 of the pane are arranged respectively in the part of the pane oriented forwards and in the part of the window facing the rear of the vehicle.
- the top edge 25 and the bottom edge 26 of the window are arranged respectively in the part of the window oriented towards the roof and in the part of the window oriented towards the ground on which the vehicle is resting.
- the window 2 is partially laminated, it comprises a main part which is laminated and in this laminated part, the window comprises, from the outside inwards, at least, in this order: an outer glass sheet, an spacer of adhesive material then an inner glass sheet; however, it is possible for at least one other sheet to be interposed between the outer sheet of glass and the interlayer sheet of adhesive material or between the interlayer sheet of adhesive material and the inner sheet of glass.
- the outer sheet of glass may be a sheet of glass which has undergone a thermal bending operation before the manufacture of the partially laminated pane and which has a thickness of between 2.85 and 4.85 mm, for example 3.50 mm.
- the outer glass sheet can have surface stresses of at least 80 MPa while being less than 200 MPa.
- the inner glass sheet may be a glass sheet which has undergone a thermal tempering or semi-tempering operation, and having a thickness of between 0.70 and 2.60 mm, or even between 0.70 and 2.50 mm, or even between 0.70 and 2.30 mm, or even between 0.70 and 2.10 mm, for example 1.10 mm or 1.60 mm.
- Hardening or semi-hardening operations have the advantage of being very quick to perform.
- the tempering or semi-tempering operation makes it possible to introduce surface stresses of the order of 20 MPa, 30 MPa and 40 MPa respectively on a sheet of glass having a thickness of approximately 1. 10 mm, about 1.60 mm and about 2.10 mm.
- the inner glass sheet may be a glass sheet having undergone a chemical toughening operation and having a thickness of between 0.30 and 1.60 mm, or even between 0.50 and 1.50 mm, or even between 0. 70 and 1.20 mm, for example 1.10 mm.
- a chemical quenching operation makes it possible to introduce surface stresses of at least 200 MPa.
- the sheet of intermediate adhesive material is for example a polyvinyl butyral (PVB) sheet having a thickness of between 0.30 and 1.50 mm, for example 0.78 mm.
- This sheet of adhesive material preferably has the same dimensions of length along the X axis and height along the Z axis as the inner glass sheet.
- the outer glass sheet is the sheet of the laminated pane which is the outermost.
- the broken line called “line of vision” or “limit of vision” VL materializes the top of the box of the door inside which the glazing 1 slides.
- This line of vision VL achieves, when the glazing is considered vertically, a separation between on the one hand a hidden part of the glass HP which is located under the line of vision VL and which is intended to be hidden inside the door regardless of the position of the window relative to said door and on the other hand a visible part of the window VP which is located above the line of vision VL.
- the glazing has one, or even two, fixing zones F, each zone being intended to accommodate means for allowing the mobility of the window in vertical translation relative to a door of the vehicle .
- each fixing zone F comprises a window holder 6 which is fixed to the window, as explained in more detail below.
- the glazing thus comprises, in addition to the window 2, along at least a part of at least one bottom edge 26, at least one window holder 6 which is intended to accommodate an attachment element, not shown , the purpose of which is to make it possible to attach the glass holder in a movement system for raising and lowering the glazing.
- the glazing in its configuration of use, here comprises a single pane holder.
- each attachment zone F is non-laminated in the entire zone: at least one of the three elements that make up the minimum lamination in the laminated part is not present in the whole of this ( or these) attachment zone(s).
- the bottom edge of the inner glass sheet as well as the bottom edge of the adhesive sheet of adhesive material are much higher than the bottom edge of the outer glass sheet.
- the bottom edge of the inner sheet of glass and the bottom edge are located approximately halfway along the vertical between the line of vision VL and the bottom edge of the outer sheet of glass.
- no fixing zone F of the glazing has a fixing hole.
- the window holder 6 has in cross section substantially a U-shape which embeds a longitudinal part of the bottom edge 26, without itself being in contact with the window 2.
- the means for allowing the mobility of the window 2, in translation relative to a door of the vehicle comprise at least one window holder 6 having in cross section substantially an inverted h shape or in the shape of a tuning fork , i.e. a U-shape with a tail extending opposite the two side walls of the U-shaped part.
- the (or each) window holder can be made of plastic material, for example polyamide, polybutylene terephthalate, or of metal alloy, for example aluminum alloy.
- Each window holder 6 thus has:
- - a first part consisting of two parallel walls 63, 64, connected at their base and forming a longitudinal groove, that is to say forming a U-shape in cross section, and - A second part consisting of a tail 65, or a foot, extending opposite the walls 63, 64 with respect to the base connecting these walls.
- the tail 65 is intended to be connected to a motorized drive system not shown to allow the raising and lowering of the glazing 1 in the door of the vehicle.
- This h-shape of the window holder is particularly advantageous because it allows the transmission of forces between the window holder and the window over a large surface area corresponding to the sum of the interior surfaces of the walls 63, 64.
- the assembly is carried out in such a way that said walls 63, 64 of said h-shape encase the pane 2 in its lower part, the tail 65 then being substantially in the extension of the pane 2.
- the assembly of the pane holder to the pane 2 is carried out on a reference frame 10 allowing tolerances to be checked on the pane holder/pane assembly.
- the window is correctly positioned (“focused”) in an assembly template having a plurality of positioning stops Y1, Y2, Y3, Y4 which represent the plane of nominal shape of the glass on the vehicle.
- the positioning stops which are essentially along the Y axis: Yl, Y2, Y3, Y4, are located on vertical uprights, respectively RY1, RY2, RY3, RY4.
- the window holder 6 is positioned opposite the edge of the window 2 and a bead of glue 9 is applied so that said glue 9 is positioned in the U-shaped part, between the window 2 and the glass holder 6, for example in the form of a layer of glue.
- glue for the glue to be well located in the U-shaped part, it is possible for example to place a bead of glue 9 on the opening of the U-shaped part before setting this part on the edge of the window, as seen in [Fig. 4], the content of which is detailed below.
- FIG. 3 shows, with the double arrow A, the proper positioning of the window holder 6, carried by a window holder guide device 60, in the frame 10 so that the U-shaped part encases the edge of the window, with the glue 9 between this U-shaped part and the window 2.
- the window holder 6 has at least one, and preferably several, lateral extension(s) 7a, 7b, 7c, 7d; 7, 7', distinct from the said U-shaped part.
- the window holder 6 has several lateral extension(s) 7a, 7b, 7c, 7d, separate(s) from said U-shaped part and each being in the form of a plate 70 intended to be in contact with a face of the pane 2 or close to this face, this plate being connected to the U-shaped part by two horizontal connecting arms 71, 71' (according to Faxe Z).
- Each lateral extension 7a, 7b, 7c, 7d further comprises here respectively a hole 72a, 72b, 72c, 72d.
- the window holder comprises four lateral extensions 7a, 7b, 7c, 7d: two lateral extensions 7a, 7b in contact with the inner face 22, located one to the left and F the other to the right of the part in U and two lateral extensions 7c, 7d in contact with the outer face 20, located one to the left and the other to the right of the part in
- the four lateral extensions are of identical general shape and the extensions located to the left and to the right of the U-shaped part are symmetrical to each other with respect to a vertical axis.
- Each extension has a length L7, according to Faxe X which is between 1/20 th and 1/5 of the length Le of the U-shaped part; here the length L7 is approximately l/10th of the length Le of the U- shaped part.
- Each extension has a height FL, according to Faxe Z which is between 1/2 and 9/10th the height H 6 of the U- shaped part which is opposite the inner face 22 or the outer face 20 ; here the height FL is about 8/10 th of the height FL.
- the extensions do not extend higher than the U-shaped part, and do not extend to the edge between face 20 or 22 and edge 21, in order to leave free surface of face 20, 22 on the one hand between the top of the extension and the line of vision VL and on the other hand between the bottom of the extension and the edge which is between the face 20 or 22 and the edge 21.
- a second variant illustrated in [Fig. 9] to [Fig.
- the window holder 6 has several lateral extension(s) 7, 7', separate(s) from said U-shaped part and each being in the form of a lateral U, seen in cross-section, section identical to the central U-shaped part.
- Each lateral extension is intended to embed the edge of the pane 2, at a distance from the faces 20, 22 and the edge 21 of the pane 2.
- Each lateral extension 7, 7' further comprises here respectively a hole 72, 72' located opposite the inner face 22.
- the glass holder has two lateral extensions 7, located one to the left and the other to the right of the central U-shaped part
- the two side extensions are of identical general shape and are symmetrical to each other with respect to a vertical axis.
- the lateral extensions 7, 7' are linked to the wall 63 of the central U-shaped part by horizontal link plates 73, 73' (along the axis Z) located in the lateral extension of this wall 63 and are linked to the wall 64 of the central U-shaped part by horizontal connecting plates (along the Z axis) located in the lateral extension of this wall 64.
- Each extension has a length L7, along the X axis, which is between 1/20 and 1/5 of the length Le of the U-shaped part; here the length L7 is approximately l/10th of the length Le of the U- shaped part.
- Each extension has a height FL, along the Z axis which is between 1/2 and 9/10th the height H 6 of the central U-shaped part which is opposite the inner face 22 or the exterior face 20; here the height FL is identical to the height FL.
- the extensions do not extend higher than the central U-shaped part, and do not extend lower than the central U-shaped part, in order to have the largest possible free surface in relation to the sides 20, 22 and edge 21.
- the extensions are preferably made of the same material as the U-shaped part; they are preferably integral with the U-shaped part.
- This positioning is the final positioning that is desired in the final glazing.
- the thickness of the adhesive 9 is not uniform from one pane to another of the same series and varies according to the actual geometry of each pane in the fixing area.
- the fast-hardening adhesive material 8 makes it possible to freeze the specific position of the pane holder and the pane, which may be different for each glazing of the same series, while the glue 9 achieves the chemical adhesion between the pane glass and glass.
- the fast-curing adhesive material 8 makes it possible in particular to fix the position along the Y axis with very high precision, taking into consideration that the shape of the window itself along this Y axis varies from one window to the another for the same series of glazing.
- this material When the quick-hardening plastic material 8 is applied to a side extension 7a, 7b, 7c, 7d, this material preferably completely covers the plate: 71 and overlaps, above, below and on the sides of the plate 71 in order to to freeze the position of the lateral extension 7a, 7b, 7c, 7d vis-à-vis the face 20 or 22 of the pane 2. If a hole 72a, 72b, 72c, 72d is present, the plastic material 8 to rapid hardening penetrates into the hole so as to come into contact with the face 20 or 22 of the pane 2 and thus increase the precision of the setting of the position of the lateral extension 7a, 7b, 7c, 7d with respect to the face 20 or 22.
- the plastic material 8 with rapid hardening can be applied so that it encases an edge of the pane 2: each application of plastic material 8 with hardening fast is then applied and glued against the outer face 20, against the edge 21 and against the inner face 22 da ns the attachment area.
- Each application of fast hardening plastic material 8 is preferably in one piece because the strength of the wedging is thus stronger.
- Each application of rapid hardening plastic material 8 here has a length Ls (along the X axis) greater than the length L 7 of the lateral extensions 7a, 7b, 7c, 7d covered: the plastic material 8 with rapid hardening projects beyond, laterally, the lateral extensions 7a, 7b, 7c, 7d.
- the fast hardening plastic material 8 When the fast hardening plastic material 8 is applied under a lateral extension 7, 7', this material preferably penetrates completely between on the one hand the faces 20 and 22 of the pane 2, as well as its edge 21, and on the other apart from the lateral extension 7, 7' in order to fix the position of the extension of the lateral extension 7, 7' with respect to the pane 2. If a hole 72, 72' is present, the plastic material 8 with rapid hardening penetrates into the hole so as to come into contact with the face 20 or 22 of the pane 2 and thus increase the precision of the timing of the position of the lateral extension 7, 7' vis-à-vis the both side 20 and side 22.
- the application of the quick hardening plastic material 8 is preferably made through the wall of the side extension 7, 7', through the hole 72, 72'.
- These injection holes 80, 80' are located at the bottom of the U-shape, in order to make it possible to carry out injections opposite the edge 21 of the window 2 and that the injected material is then distributed correctly in the volume of the U shape.
- the fast hardening plastic material 8 is applied in such a way that it encases an edge of the pane 2: each application of fast hardening plastic material 8 is applied against the outer face 20, against the edge 21 and against the inner face 22 in the fixing zone.
- the glue can overflow near or in contact with the connecting plate 73, 73', in the hollow 74, 74'; this will not interfere with the adhesion of the fast hardening plastic material 8 on the one hand to the lateral extension 70, 70' and on the other hand to the pane 2.
- Each application of rapid hardening plastic material 8 is preferably in one piece because the wedging force is thus stronger.
- Each application of fast hardening plastic material 8 here has a length Ls (along the axis X) identical to the length L 7 of the lateral extensions 7, 7': the fast hardening plastic material 8 does not overflow beyond this, laterally , lateral extensions 7, 7', neither to the left nor to the right; the plastic material 8 with rapid hardening does not overflow above the lateral extension 7, 7' either.
- the fast curing plastic material 8 can be applied to be both under a side extension and both on this side extension and this can apply to several side extensions or even to all side extensions of the glass holder.
- the quick-hardening plastic material 8 is on one or more lateral extension(s) and is under one or more other lateral extension(s).
- the space available in the door intended to accommodate the glazing can influence the choice of the positioning of the plastic material 8 with rapid hardening with respect to the lateral extensions.
- the rapid hardening plastic material 8 can be applied to be under a lateral extension for certain glazings of this series and on this lateral extension for others panes since the final position of a pane holder depends on the actual configuration of each pane.
- the fast-hardening plastic material 8 it is therefore possible for the fast-hardening plastic material 8 to be applied:
- the fast-curing plastic material 8 may, for example, be a material which cures in 60 seconds or less. It is here a thermoplastic or thermosetting material and it preferably has, in the hardened state, a hardness of at least 60 Shore A II can in particular be a thermoplastic elastomer (TPE), a Polyamide , ... This is in particular a "hotmelt Tecbond 240-12-300" material.
- TPE thermoplastic elastomer
- Polyamide Polyamide
- ... This is in particular a "hotmelt Tecbond 240-12-300" material.
- all the applications of the fast hardening plastic material 8 are preferably carried out at the same time in order to reduce the total duration of the manufacturing process.
- the adhesive 9 is for example a thermosetting resin, for example based on polyurethane, single or two-component, with or without an accelerator.
- the hardening time of the glue does not matter and it can be long because the glass holder is already correctly fixed to the glass by the plastic material 8 with rapid hardening.
- the pane 2 is held in the reference frame 10 without moving.
- the glazing 1 can be immediately removed from the reference frame 10; it is not necessary to wait for the polymerization or hardening of the glue 9.
- the physical wedging of the window holder to the window 2 by the plastic material 8 is carried out quickly and it is reliable: the chemical fixing by the glue 9 can be done without risk that the window holder moves vis-à-vis the window.
- This chemical fixing is reliable and precise; it is not necessary to complete it with a mechanical attachment of the glass holder to the glass.
- the door of the vehicle may comprise at least one part without a pillar.
- the door it is possible that the door:
- the - does not have a front side pillar and that it is the adjacent bodywork part, otherwise called “the A-pillar” or “A-pillar” in English, which guides the glazing, and/or
- the - does not have a rear side pillar and that it is the adjacent bodywork part, otherwise called "the B-pillar” or "B-pillar” in English, which guides the glazing.
