Description

Title of the invention: 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 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.

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

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

[0004] The invention relates to the field of glazing comprising a pane and at least one pane holder 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 usually includes at least one glass holder, which provides support for the glazing and allows the glass to be operated. Several types of glass holders currently exist for different glazing options, with or without a frame. These glass holders can be made of plastic (particularly fiberglass-reinforced plastic), metal (aluminum), or alloy, and connect the glazing to the window lifting system. A glass holder generally consists of two main parts: firstly, a U-shaped bracket that is bonded to the glass with standard PU adhesive, and secondly, a tail designed to allow the glazing to be attached to the window lifting system.

[0007] 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 smart glazing, the user or passenger recognition system, and all other electrical functions that can be added to the side windows.

[0008] This cable management is mainly useful for movable side windows installed on the rear and front doors.

[0009] To achieve this objective, the invention proposes 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 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.

[0010] 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.

[0011] Said glazing movement is preferably a translation along the vertical axis in the vehicle's frame of reference. For this type of glazing, it is completely unexpected to require a cable because the movement is frequently used, and it has been considered until now that this use was too frequent to justify adding such a feature.

[0012] In a first variant, said retaining device is a clamp and comprises a first elastic arm positioned opposite said outer face of the glass, a second elastic arm positioned opposite said inner face of the glass and a base connecting these elastic arms; this clamp may be independent of said glass holder.

[0013] In a second variant, said retaining device is linked to said glass door, and comprises an inner arm positioned opposite said inner face of the glass and an outer arm positioned opposite said outer face of the glass.

[0014] In both variants, the cable routing is thus well controlled, with minimal bulk, each cable can be tensioned in its service position.

[0015] More particularly, 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.

[0016] This ensures that the cable is properly fixed and held on either the outer side of the glass or the inner side of the glass.

[0017] Said glazing movement is preferably a translation along the vertical axis in the vehicle's frame of reference. For this type of glazing, translational movements are frequent, and it is important that the cable be securely held.

[0018] More specifically, said at least one stirrup is elastic.

[0019] Installation is thus made easier for the operator.

[0020] More particularly, said outer arm or said inner arm comprises a plurality of said stirrups defining a non-rectilinear trajectory of said at least one cable.

[0021] It is thus possible to create complex trajectories with simple fastening means.

[0022] More particularly, 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.

[0023] Fixing the glass by gluing is thus facilitated.

[0024] 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 bottom 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.

[0025] A cable can thus be held securely on (or against) an edge of the glass, without being able to move.

[0026] More particularly, 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 window.

[0027] This arrangement facilitates fixing by gluing between the clamp and the glass.

[0028] 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.

[0029] More particularly, 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.

[0030] This accessory and its power supply are thus invisible to the vehicle user.

[0031] 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.

[0032] The power supply for the electrical accessories of the glazing of this vehicle is easy and safe, the seals are ensured.

[0033] 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.

[0034] 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.

[0035] Preferably, for this method, 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.

[0036] The installation of the wiring for the electrical accessories of the glazing is thus quick, easy and reliable.

[0038] The figures illustrate the manufacture of a glazing 1 according to the invention. This glazing 1 is more particularly a vehicle glazing, movable in translation under the action of a window lift mechanism or similar.

[0039] 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 figures [Fig.4], [Fig.5], [Fig.7], [Fig.8].

[0040] The translational movement of the glazing is here a vertical movement. This concerns a side window of a vehicle that can be moved vertically.

[0041] The window 2 has a lower part, limited above by a visibility line LV and intended to be hidden from the user, as seen in [Fig.1].

[0042] The glazing 1 includes at least one glass holder 69, referred to as "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.

[0043] The term "shaft" here refers to a mechanical linkage element with a window operating device 2. This shaft may be an attachment rod, for example, a threaded rod, which allows the window holder, and thus the glazing, to be attached to a glazing movement system, in order to allow its movement relative to a fixed part of the vehicle. The terms "fastener" or "attachment" here refer to mechanical fasteners, which are attached and detached manually or with the aid of a mechanical tool. What is attached is thus in a fixed position; hooking, screwing, or clipping each constitutes an attachment. The window holder shaft mentioned above is therefore an attachment shaft.

[0044] By "fixation" we mean here chemical fixings, which generate irreversible molecular modifications, except by breaking the bond and rendering the glass holder unusable; gluing is a fixing.

[0045] 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.

[0046] 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.

[0047] The glass holder 69 comprises an outer arm 691 positionable opposite the outer face 20 of the glass 2, and an inner arm 692 positionable opposite the inner face 22 of the glass 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 2 together, 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 against the edge 21, and to push this at least one cable 401, 402, against the outer face 20 and / or against the inner face 22 and / or against 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 support each other in a position to hold the glass 2, and each suitable for forming a gluing surface.

[0048] 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 particularly, this bracket 690 is elastic. More particularly, the outer arm 691 includes a plurality of such brackets 690 defining a non-straight path for the cable 401, 402.

[0049] Advantageously, the outer arm 691 and the inner arm 692 of the glass holder 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.

[0050] 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.

[0051] More particularly, the first elastic arm 61 and the second elastic arm 62 of the gripper 60 respectively comprise a first bearing surface 610 and a second bearing surface 620 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” profile open on the side of the window 2 having, opposite the opening, a base 63 arranged to limit or cancel 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.

[0052] Advantageously, the clip 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 clip 60 to the glass 2.

[0053] More particularly, the glazing 1, once assembled, comprises an inner layer of glue between the inner support surface and the glass 2, and an outer layer of glue between at least one outer support surface and the glass 2.

[0054] More particularly, 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.

[0055] 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.

[0056] More specifically, the glazing 1 comprises at least two glass-doors 69.

[0057] The invention also relates to a vehicle 1000 comprising at least one element of bodywork 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.

[0058] 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.

[0059] 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 achieved by inserting, in a first operation 100, at least one cable 401, 402, into at least one retaining device embedded in the lower part of the glazing 2 and arranged to guide the at least one cable 401, 402, and to hold it in contact with the edge 21 and / or with said outer face 20 and / or with 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 glass 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.

[0060] 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.

[0061] The objective of gluing 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.

[0062] In the illustrated example, clips on the edge of the glass are combined with clips integrated on the glass holder.

[0063] The design of all the clips is minimized with regard to their dimensions, in order to be able to mount and dismount the glass in the door by way of the sealing channel having elastic lips pressed against the glass.

[0064] In summary, the present invention allows a window holder to be reliably and compactly attached to a pane of glass in a glazing unit equipped with a cable. The compact design of the window holder allows for a reduction in its height and / or thickness, respectively along the vertical axis Z of the vehicle and along the transverse axis Y of the vehicle for a side window; this therefore reduces the space required inside the door and thus increases the available volume inside the vehicle. 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.

[0065] The invention thus provides a glazing equipped with at least one very compact and very light glazing holder, whose axis can be positioned precisely and which is very securely fixed to the glazing without risk of transmitting damaging force to the glazing.

[0066] The invention is a practical solution for the quick, simple, and efficient attachment of a glazing cable to a glazing movement system, offering the possibility that the glazing holder is the same whether the glazing pane is laminated or not; thus, when a series of vehicles provides for certain models of the series with laminated glazing and for other models of the series with monolithic glazing, a holder-

[0067]

[0068] Identical glass for both series can be used. The invention provides a particularly compact and reliable solution for a curved window. The invention ensures assembly security and facilitates the operator's work. The invention allows for the easy and secure insertion of components, such as cables, lighting elements like LED modules, defrosting elements, or others, and allows for the possible disassembly of the glass.
