Description

GLAZING WITH GLAZING HOLDER AND CABLE AND METHOD FOR MANUFACTURING SAID GLAZING

[0001] The invention relates to a vehicle glazing that can be moved in translation, comprising a pane of glass, preferably laminated, said pane having an outer face intended to be oriented towards an outside space, an edge and an inner face intended to be oriented towards an inside space, said pane having a lower part, limited above by a line of sight and intended to be hidden from the user of the vehicle, and said glazing comprising at least one glass holder, having an opening arranged for the passage of a shaft for driving said glass.

[0002] The invention also relates to a vehicle comprising at least one such glazing.

[0003] The invention also relates to a method of manufacturing said glazing.

[0004] The invention relates to the field of glazing comprising a pane of glass and at least one pane of glass to allow said pane to be moved by translation, and in particular to the field of vehicle glazing, especially motor vehicles.

[0005] The invention is described with regard to a vehicle glazing application comprising a window, in particular a laminated window comprising an outer sheet of glass, an inner sheet of glass and an interlayer sheet of adhesive material located between said two sheets of glass, said window having an outer face intended to be oriented towards an outer space, an edge and an inner face intended to be oriented towards an inner space.

[0006] Such glazing typically includes at least one window holder, which supports the glazing and allows the window to be operated. Several types of window holders are currently available for different glazing options, with or without frames. These window holders can be made of plastic (particularly fiberglass-reinforced plastic), metal (aluminum), or alloy, and connect the glazing to the vehicle's window regulator system. A window holder generally consists of two main parts: a U-shaped bracket that is bonded to the glass with standard polyurethane adhesive, and a tail designed to allow the glazing to be attached to the window regulator system.

[0007] Patent applications CN 104015590 and DE 10029701 expose glass door configurations.

[0008] European patent application No. EP 3334884 exposes in sala the possibility of operating the connection of the termination of an electrical connection cable in the environment of a glass door.

[0009] The objective of this invention is to describe the technical solution for managing the electrical cable requirements for live electrical functions such as the LED (light-emitting diode) lighting module, the defrosting system, the electrochromic glazing system, also known as dynamic glazing or intelligent glazing, the user or passenger recognition system, and all other electrical functions that can be added to the movable side windows.

[0010] This cable management is primarily useful for movable side windows installed on the front and rear doors.

[0011] To achieve this objective, the invention proposes a vehicle glazing according to claim 1. This glazing is movable in translation and comprises a pane of glass, preferably laminated, said pane having an outer face intended to be oriented towards an outer space, an edge and an inner face intended to be oriented towards an inner space, said pane having a lower part, limited above by a line of sight and intended to be hidden from the user, and said glazing comprising at least one glass holder having an opening arranged for the passage of a shaft for driving said pane.

[0012] According to the invention, said glazing comprises at least one cable and at least one retaining device embedding said lower part of said glazing and arranged to guide said at least one cable and hold it in support against said edge of the glazing and / or against said outer face of the glazing and / or against said inner face of the glazing.

[0013] The said retaining device guides the said cable on each side of the device; it is not a terminal connection device, into which the cable terminates, but a device for the passage of the cable. The cable is thus present upstream and downstream of the retaining device.

[0014] The movement of the glazing is preferably a translation along the vertical axis within the vehicle's frame of reference. For this type of glazing, it is completely unexpected to require a cable, as the movement is frequently used and it has been considered until now that this usage was too common to justify adding such a feature.

[0015] In a first variant, the said holding device is a clamp and comprises a first elastic arm positioned opposite the said outer face of the glass, a second elastic arm positioned opposite the said inner face of the glass and a base connecting these elastic arms; this clamp may be independent of the said glass holder.

[0016] In a second variant, the said retaining device is linked to the said glass door, and comprises an inner arm positioned opposite the said inner face of the glass and an outer arm positioned opposite the said outer face of the glass.

[0017] In both of these variants, the cable routing is thus well controlled, with minimal bulk, each cable can be tensioned in its service position.

[0018] More specifically, said outer arm or said inner arm includes at least one bracket arranged to guide said at least one cable and to press it against said outer face of the glass or respectively to press it against said inner face of the glass.

[0019] This ensures that the cable is properly fixed and held securely on either the outside or inside side of the glass.

[0020] The movement of the glazing is preferably a translation along the vertical axis within the vehicle's frame of reference. For this type of glazing, translational movements are frequent, and it is important that the cable is securely fastened.

[0021] More specifically, at least one stirrup is elastic.

[0022] This makes installation easier for the operator.

[0023] More specifically, said outer arm or said inner arm comprises a plurality of said stirrups defining a non-rectilinear trajectory of said at least one cable.

[0024] It is therefore possible to create complex trajectories with simple means of attachment.

[0025] More specifically, said outer arm and said inner arm of said glass carrier together form a hollow "U" profile open on the side of said glass, and said outer arm has at least one external bonding surface positionable opposite said outer face of said glass on said inner arm, and said inner arm has at least one internal bonding surface positionable opposite said inner face of said glass.

[0026] This makes it easier to fix the glass by gluing it in place.

[0027] More particularly, said first elastic arm and said second elastic arm of said clamp respectively comprise a first bearing surface and a second bearing surface arranged to bear on said outer face and said inner face or vice versa, said first elastic arm and said second elastic arm together form a hollow “U” profile open on the side of said window comprising, opposite the opening, a base arranged to limit or cancel the movement of said at least one cable in a service position in which said clamp is clipped and / or glued to said window.

[0028] A cable can thus be held securely on (or against) an edge of the glass, without being able to move.

[0029] More specifically, said clamp includes at least one tab having an internal gluing surface arranged to receive glue and / or a double-sided adhesive for fixing said clamp to said glass.

[0030] This arrangement facilitates fixing by gluing between the clamp and the glass.

[0031] Preferably, said glazing comprises at least one clamp according to the invention, and preferably several clamps according to the invention, and at least one glass holder according to the invention, and preferably several glass holders according to the invention.

[0032] More specifically, said glazing includes at least one electrical accessory powered by said at least one cable, positioned below said line of sight and intended to be hidden from the user, comprising at least one electrical component held on said glazing by at least one tab glued with glue or adhesive.

[0033] This accessory and its power supply are therefore invisible to the vehicle user.

[0034] The invention further relates to a vehicle comprising at least one bodywork element carrying at least one such glazing, said at least one bodywork element being arranged to carry at least one external sealing gasket and / or at least one internal sealing gasket respectively comprising at least one external scraping lip or one internal scraping lip each arranged to bear against said glazing.

[0035] Powering the electrical accessories for the glazing of this vehicle is easy and safe, and sealing is ensured.

[0036] The invention further relates to a method of manufacturing a glazing that can be moved in translation, said glazing comprising on the one hand a pane of glass, preferably laminated, said pane having an outer face intended to be oriented towards an outer space, an edge and an inner face intended to be oriented towards an inner space, said pane having a lower part, limited above by a line of visibility and intended to be hidden from the user, and said glazing comprising on the other hand at least one glass holder having an opening arranged for the passage of a shaft for driving said pane.

[0037] According to the invention, in this method at least one cable is integrated into said glazing, and the attachment of said at least one cable to said glazing is carried out by inserting, in a first operation, said at least one cable into at least one retaining device encasing said lower part of said glazing and arranged to guide said at least one cable and hold it in support against said edge of the glazing and / or against said outer face of the glazing and / or against said inner face of the glazing.

[0038] Preferably, for this process, said at least one glass holder and / or said at least one clamp is, in a second operation, fixed to said glass by clipping and / or gluing.

[0039] The installation of the wiring for the electrical accessories of the glazing is therefore quick, easy and reliable.

[0041] The figures illustrate the manufacture of a glazing unit 1 according to the invention. This glazing unit 1 is more particularly a vehicle glazing unit, movable in translation under the action of a window lift mechanism or similar.

[0042] The translationally movable glazing 1 comprises on the one hand a pane 2, preferably laminated, this pane 2 having an outer face 20 intended to be oriented towards an exterior space EXT, an edge 21, and an inner face 22 intended to be oriented towards an interior space INT, as seen in the figures,,,.

[0043] The translational movement of the glazing here is a vertical movement. This is a side window of a vehicle that can be moved vertically.

[0044] The window 2 has a lower part, limited above by a visibility line LV and intended to be hidden from the user, as seen on the.

[0045] The glazing 1 includes at least one glass holder 69, called a "holder", in particular monobloc, for holding the glass 2, and having at least one opening 68, arranged for the passage of a shaft for driving the glass 2.

[0046] The term "shaft" here refers to a mechanical linkage to a window operating mechanism. This shaft may be a threaded rod, for example, that attaches the window carrier, and thus the glazing, to a glazing movement system, allowing its movement relative to a fixed part of the vehicle. The terms "fastener" or "attachment" here refer to mechanical fasteners that attach and detach manually or with a power tool. The attached component is thus in a fixed position; hooking, screwing, or clipping each constitutes a fastener. The window carrier shaft mentioned earlier is therefore a fastener shaft.

[0047] By "fixation" we mean chemical fixings, which cause irreversible molecular changes, unless the bond is broken and the glass holder becomes unusable; gluing is a fixing.

[0048] According to the invention, this glazing 1 comprises at least one cable 401, 402, for the electrical supply of a component or accessory, and at least one retaining device embedding the lower part of the glazing 2 and arranged to guide this at least one cable 401, 402, and to hold it in support on (or against) the edge 21 and / or on (or against) the outer face 20 of the glazing 2 and / or on (or against) the inner face 22 of the glazing 2.

[0049] This holding device comprises either at least one glass holder 69, or at least one clamp 60, or both at least one glass holder 69 and at least one clamp 60.

[0050] The glass holder 69 comprises an outer arm 691 positionable opposite the outer face 20 of the glass pane 2, and an inner arm 692 positionable opposite the inner face 22 of the glass pane 2. This outer arm 691 and this inner arm 692 are connected by a base 696 and together constitute clamping means arranged to clamp the glass pane 2, to press the outer arm 691 against the outer face 20 and / or to press the inner arm 692 against the inner face 22 and / or the edge 21, and to push at least one cable 401, 402 against the outer face 20 and / or the inner face 22 and / or the edge 21. The outer arm 691 and the inner arm 692 respectively comprise an outer bearing surface and an inner bearing surface, which are arranged to bear one on top of the other in a position to hold the glass 2, and each suitable for forming a gluing surface.

[0051] Advantageously, the outer arm 691 includes at least one bracket 690 arranged to guide a cable 401, 402, and to hold it against the outer face 20 of the window 2. More specifically, this bracket 690 is elastic. More specifically, the outer arm 691 includes a plurality of such brackets 690 defining a non-straight path for the cable 401, 402.

[0052] Advantageously, the outer arm 691 and the inner arm 692 of the glass carrier 69 together form a hollow "U" profile open on the side of the glass 2, and the outer arm 691 has at least one external bonding surface positionable opposite the outer face 20 of the glass 2 on the outer arm 691, and the inner arm 692 has at least one internal bonding surface positionable opposite the inner face 22 of the glass 2.

[0053] Similarly, the clamp 60 includes a first elastic arm 61 and a second elastic arm 62 and a base 66 connecting these elastic arms, which are arranged to clamp the glass 2 together, to encase it at least one cable 401, 402, and to hold it in contact with the edge 21.

[0054] More specifically, the first elastic arm 61 and the second elastic arm 62 of the clamp 60 each have a first bearing surface 610 and a second bearing surface 620 respectively, arranged to bear against the outer face 20 and the inner face 22, or vice versa. The first elastic arm 61 and the second elastic arm 62 together form a hollow U-shaped profile, open on the side facing the window 2, and having, opposite the opening, a base 63 arranged to limit or eliminate the movement of the cable 401, 402, in a service position in which the clamp 60 is clipped and / or glued to the window 2.

[0055] Advantageously, the clamp 60 includes at least one tab 65 having an internal gluing surface arranged to receive glue and / or a double-sided adhesive for fixing the clamp 60 to the glass 2.

[0056] More specifically, the glazing 1, once assembled, has an inner layer of adhesive between the inner support surface and the glazing 2, and an outer layer of adhesive between at least one outer support surface and the glazing 2.

[0057] In particular, the glazing 1, once assembled, has an inner layer of glue between the first elastic arm 61 and the glazing 2, and an outer layer of glue between the second elastic arm 62 and the glazing 2. This layer of glue can be replaced by a double-sided adhesive, or similar.

[0058] The glazing 1 includes at least one electrical accessory 4 powered by at least one cable 401, 402, positioned below the line of sight LV and intended to be hidden from the user, comprising at least one electrical component 41 held on the glazing 2 by at least one tab 40 glued with glue or adhesive 42.

[0059] More specifically, glazing 1 includes at least two glass doors 69.

[0060] The invention further relates to a vehicle 1000 comprising at least one bodywork element 9 carrying at least one such glazing 1; this at least one bodywork element 9 is arranged to carry at least one external sealing gasket 73 and / or at least one internal sealing gasket 72, comprising respectively at least one external scraping lip 730 or one internal scraping lip 720 each arranged to bear against the glass 2.

[0061] The invention further relates to a method of manufacturing such a glazing 1 which can be moved in translation, in particular in height, along the direction Z of the gravity field, which constitutes a reference trihedron with a longitudinal direction X (corresponding, in the case of vehicle glazing, to the movement of this vehicle in a straight line), and a transverse direction Y, all orthogonal to each other.

[0062] In this method at least one cable 401, 402, is integrated into the glazing 1, and the attachment of at least one cable 401, 402, to the glazing 2 is carried out by the insertion, in a first operation 100, of at least one cable 401, 402, into at least one retaining device embedding the lower part of the glazing 2 and arranged to guide the at least one cable 401, 402, and to hold it in support on the edge 21 and / or on said outer face 20 and / or on said inner face 22; this retaining device comprises, either at least one glazing holder 69, or at least one clamp 60, or at least one glazing holder 69 and at least one clamp 60.The guiding and holding of the cable is achieved either by insertion between the outer face 20 of the glass 2 and a bracket 690 included in at least one glass holder 69, or by insertion between the edge 21 of the glass 2 and a base 63 of at least one clamp 60, or both, either by insertion between the inner face 22 of the glass 2 and a bracket 690 included in at least one glass holder 69, and by insertion between the edge 21 of the glass 2 and a base 63 of at least one clamp 60. In this method, at least one glass holder 69 and / or said at least one clamp 60 is fixed to the glass 2 in a second operation 200 by clipping and / or gluing.

[0063] In summary, the present invention provides a simple and effective way to guide the cable and prevent interference with the environment. In the case of a movable window (up and down), the cable is secured to prevent damage and ensure electrical continuity throughout the vehicle's lifespan.

[0064] The objective of attaching clips to the surface of the glass and guiding the cable in front of the edge of the glass is thus achieved in a simple way.

[0065] In the illustrated example, clips on the edge of the glass are combined with clips integrated on the glass holder.

[0066] The design of all the clips is minimized in terms of their dimensions, in order to be able to mount and dismount the glass in the door via the sealing channel which has elastic lips pressed against the glass.

[0067] In summary, the present invention allows for the reliable and compact attachment of a window holder to a pane of glass in a cable-equipped glazing unit. The compact design of the window holder allows for a reduction in its height and / or thickness, respectively along the vehicle's vertical Z-axis and transverse Y-axis for a side window; this reduces the space required inside the door and thus increases the available interior volume. It also allows for a lighter glazing unit. The combination of the inner and outer flanges ensures that the forces are evenly distributed on each side of the glass, which is not subjected to stress by the window holder, thus eliminating the risk of damaging the laminated glass.

[0068] The invention thus provides a glazing equipped with at least one very compact and very light glass holder, whose axis can be positioned with precision and which is very securely fixed to the glass without risk of transmitting damaging force to the glass.

[0069] The invention provides a practical solution for the quick, simple, and efficient attachment of a window cable to a window movement system, offering the possibility of using the same window holder regardless of whether the window pane is laminated or not. Thus, when a vehicle series specifies laminated windows for some models and monolithic windows for others, an identical window holder can be used for both series. The invention also provides a particularly compact and reliable solution for curved windows.

[0070] The invention provides assembly safety and facilitates the operator's work.

[0071] The invention allows the easy and secure insertion of components, such as cables, light elements like LED modules, defrosting elements, or others, and allows for possible dismantling of the glass.
