Description

Technical Field

[0001] The field of the present disclosure is motor vehicles.

[0002] More precisely, the present disclosure relates to devices for openings arranged in vehicles, in particular vehicle doors.

[0003] In particular, the present disclosure relates to a vehicle door equipped with at least one substantially vertically movable glass panel, in particular for changing from a closed position to an open position, wherein the vehicle door fully or partially penetrates the lower body inner panel (of course, the movable panel is generally capable of adopting a plurality of intermediate positions).

[0004] Such a vehicle door may specifically be a side door, but the present disclosure may also be applied to, for example, swing and / or sliding doors of a vehicle, including a rear door, a tailgate, etc., or even fixed parts of a vehicle body. Background Art

[0005] Examples of such devices are described in particular in patent documents EP1422091, EP1612072 or EP3647093.

[0006] According to this method, a frame is provided on the side facing the interior of the vehicle, which frame supports one or more (conventionally two) rails, and cooperates with pads integral with the moving glass panel and fixed on its face facing the interior of the vehicle. Where applicable, the frame can be truncated and can be limited to a support column supporting the rails.

[0007] This technology is interesting because it allows to create original designs, since the traditional door frame is eliminated, while maintaining effective guidance and retention of the moving panels.

[0008] Devices comprising a glass fixing part are also known, in which an opening is arranged which can be uncovered or covered by a mobile plate guided along a track mounted on the face of the glass fixing part facing the vehicle interior. The applicant has applied for a number of patents for this method, wherein the general principle of this technology is particularly described in patent documents EP778168 and EP857844. In this case, the mobile plate usually moves along a horizontal axis and has a complex movement, called swinging.

[0009] In some cases, it would be interesting to combine both approaches, i.e. the presence of a glass fixing part and a vertically movable plate to be at least partially retracted in the inner door housing and to cover an opening in the fixing part defining its three sides, two side edges and the upper edge. However, this combination is neither easy nor straightforward. Placing an opening on the lower edge of the fixed glass plate requires a specific method for holding and moving the movable plate. It is necessary to maximize the clear opening, thereby minimizing the size of the attachment parts on the fixing part (rail, frame, etc.) and maximizing the ease and safety of assembly and installation of the device, etc.

[0010] One of the main difficulties is to ensure effective, reliable and permanent guidance of the moving plate, as well as sealing (including in the presence of high-pressure jets). Utility Model Content

[0011] In particular, it is an object of the present disclosure to alleviate these disadvantages of the prior art.

[0012] More specifically, in at least one embodiment, the present disclosure aims to provide a glass device for manufacturing a vehicle door having an effective seal.

[0013] According to at least one embodiment, it is another object of the present disclosure to provide a glass device that provides a clear opening as large as possible while being reliable and durable over time.

[0014] These objects, as well as others which will become apparent hereinafter, are achieved by a glass arrangement intended to be mounted on an inner door shell to form a motor vehicle door or body element, the glass arrangement comprising a glass fixing part and a movable glass panel which can slide along a substantially vertical axis relative to the fixing part and can selectively at least partially cover or uncover an opening in the fixing part, the movable panel being guided along a track supported by the fixing part.

[0015] According to the present disclosure, the track is fixed to the fixing part along the side edge by a bead of glue, and the frame extends at least at the side edge and the upper edge of the opening, the frame is fixed to the track at the side edge and the frame is bonded to the fixing part by the bead of glue at the upper edge.

[0016] Thus, the same rubber ring ensures that the fixing part of the rail is fixed to the side edges of the opening and the frame is fixed to the upper edge. This makes it possible in particular to reduce the width of the assembly formed by the frame and rail, in particular at the side edges, thereby increasing the clear opening. The frame can be fixed to the rail at these sides (instead of directly to the fixing part).

[0017] According to particular characteristics, the device disclosed herein comprises means for controlling the seal at the junction between the upper part of said rail and said frame.

[0018] In fact, the author recognizes that the innovative method of the present disclosure may in certain cases introduce sealing problems at the transition between the gluing of the rail and the gluing of the frame, which may require the implementation of specific measures.

[0019] According to a first embodiment of these means for controlling sealing, each of said rails supports a seal having at least two sealing lips, along which a first lip is in contact with an edge of said mobile part and a second lip is in contact with an edge of said fixed part.

[0020] This method is easy to implement and is based on the novel and non-obvious approach of having a seal with a lip along the track.

[0021] According to a second embodiment of these means for controlling the sealing, a sealing ring or seal is placed between the frame and each rail before the rubber rings (called main rubber rings) of said rails of said frame are respectively deposited on said fixing part.

[0022] This makes it possible to prevent water from passing through at the transition between the rail and the frame.

[0023] The sealing ring may in particular comprise glue or a sealant.

[0024] According to a third embodiment of these means for controlling sealing, the upper portion of each rail has a non-zero angle with respect to the horizontal, the portion of the rail remote from said opening being higher than the portion of the rail close to said opening.

[0025] This special track shape can effectively direct water to the outside.

[0026] The angle is preferably greater than or equal to 25°.

[0027] According to a fourth embodiment of these devices for controlling sealing, the upper part of said rail covers part of said frame.

[0028] Once again, this makes it possible to prevent water from passing through.

[0029] In particular, the upper portion of the rail may be cut such that the discontinuity is lower on the side facing the opening than on the side facing the fixing member.

[0030] In particular, the discontinuity may have a substantially circular arc-shaped concave shape.

[0031] Of course, two or more of these embodiments may be combined if necessary.

[0032] According to another particular aspect, the frame and / or the rail may have a vertical extension extending beyond a lower portion of the fixing part.

[0033] In particular, at least one of the extensions may support a stop to ensure that, at least when the moving plate is mounted on the fixed part, movement of the moving plate relative to the fixed part is limited in two directions substantially perpendicular to the substantially vertical axis.

[0034] This makes it possible to easily install the mobile plate.

[0035] The present disclosure also relates to a motor vehicle comprising at least one glazing arrangement as described above.

[0036] In particular, in such a vehicle, the covering device may be mounted on an upper portion of a vehicle door of the vehicle, the moving plate at least partially moving on a lower portion of the door. BRIEF DESCRIPTION OF THE DRAWINGS

[0058] Overall structure

[0059] The present disclosure therefore relates to a new method for mounting a fixed glass part and a glass moving plate of a fixed part of a door (side door, rear door, tailgate, hatch, etc.) or even of a motor vehicle body. The glass or the moving plate is aligned with at least one edge of the body and mounted flush, that is, with respect to the plane of the glass part, no frame or frame element protrudes outside the vehicle and no frame or frame element is guided to penetrate in the vertical direction into the inner door casing (or equivalent body element).

[0060] Figure 1 and Figure 2 Such a device is schematically shown from the side corresponding to the vehicle exterior to the vehicle interior respectively. The device is intended to be fixed by fixing means to an inner door shell or a vehicle body not shown, which extends below the device.

[0061] The main components of the device appear in Figure 3 Thus, the device comprises a fixed part 1, which can be a glass piece in particular, the outer edge of which corresponds to the edge of the upper part of the door. An opening 11 is cut in the fixed part, which is defined by an upper edge 111 of the fixed part and two vertical side edges 112 and 113. The lower part of the opening is not defined in the fixed part, but is formed in its lower edge in order to be able to move the moving plate 2.

[0062] Therefore, the mobile plate 2 can also be glass, designed and dimensioned to fit into the opening 11 in the closed position and to move downwards in the inner door housing in the open position. This movement can be ensured, for example, by an electric motor and a suitable transmission (not shown) connecting the bottom of the mobile plate 2 to the motor.

[0063] The mobile plate 2 receives an encapsulation 3 which in this example extends over the side edges and the upper edge of the plate. Such an encapsulation 3 may extend in particular over the edge of the mobile plate and its periphery, extending by a few millimeters or centimeters on the face facing the interior of the vehicle, for example Figure 5 and Figure 6 is shown in cross-section and commented on below.

[0064] The fixing part 1 supports the frame 4 on its face facing the interior of the vehicle at least along the upper edge 111 and the vertical side edges 112 and 113. The side parts 41, 42 of the frame support the rails 5 and / or are supported by the rails 5 so that the mobile plate 2 can be held and guided. Figure 1 and 2 As shown, the frame and / or rails extend below the fixed components 1 (components 411 and 421).

[0065] The seal 6 is installed in the frame 4 along the side and upper portion thereof.

[0066] The mobile plate 2 is provided with guide pads 7, able to cooperate with the rails 5. They can in particular be fixed directly to the enclosure, or via intermediate supports.

[0067] The frame and rails are fixed to the fixed parts by the main rubber ring, such as Figure 5 and 8 As shown in 8.

[0068] Installing Tracks and Frame – Step 1

[0069] Figure 4 is a simplified view of the device, specifying Figure 5 The location of the cross section. Figure 5 A first example of a design of a frame, rails and pads is shown.

[0070] According to this method, the frame 4 is glued to the fixed part 1 by means of rubber rings 8 which fit in recesses 4a provided for this purpose. The frame 4 supports the rails 5.

[0071] The seal 6 with three lips is fixed to the frame 4 via the attachment portion 4b on the one hand and to the rail 5 via the attachment portion 5b on the other hand.

[0072] The mobile plate 2 supports the packaging 3, whose portion 3a extends towards the interior of the vehicle by moving away from the mobile plate and forms the side and upper surfaces cooperating with the lip of the seal. This portion 3a also covers the edge of the mobile plate.

[0073] The portion 3 b extends around the periphery of the moving plate 5 on its surface facing the vehicle interior and receives the end 7 b of the pad 7 so as to hold the end 7 b.

[0074] In this embodiment, the pad has a substantially C-shaped cross section. In a way, it is folded back on itself, with the two ends 7a and 7b being substantially superimposed, one above the other (according to an axis perpendicular to the plane defined by the mobile plate). This makes it possible to reduce the width X1 of the frame, thereby benefiting from a significant clear opening (X2).

[0075] Considering the same goal, Figure 6 As shown, the frame may be narrower in the upper part (Z1), which does not contain the rails. Figure 7 , it is noted that the width of the package 3 decreases, just as the width of the frame 4 decreases, which holds the seal 6 by its two sides.

[0076] According to this embodiment, the frame is bonded to the fixing part around its entire periphery.

[0077] Installing the Tracks and Frame - Method 2

[0078] However, it is also desirable to reduce the width of the frame. Figure 8 ( Figure 4 The method shown in the cross section at a defined position in the figure makes it possible to achieve this goal.

[0079] The moving plate 2 supports the package 3, wherein the portion 3a extends away from the moving plate towards the fixed part and forms a side surface cooperating with the lip of the first sealing member 6a. The portion 3a also covers the edge of the moving plate.

[0080] The encapsulated portion 3 b extends around the periphery of the moving plate 5 on its surface facing the interior of the vehicle and receives the end 7 b of the pad 7 so as to hold the end 7 b.

[0081] In this embodiment, the pad has a generally S-shaped cross section, with the leading end 7a being substantially cylindrical, moving out of the moving plate 2, at least partially above the fixed part 1. However, in this embodiment, other cross sections are possible, including a C-shaped cross section.

[0082] According to a second method, at the fixed part, the rail 5 is bonded by its part 5a, forming a recess for receiving the rubber ring 8. This rail 5 supports the frame 4, for example by interlocking with the sides of the frame. It also supports the seal 6a by the recess 5b. This effectively reduces the overall width of the frame, thus optimizing the clear opening.

[0083] The end 4 b of the frame toward the opening supports a second sealing member 6 b in contact with the upper portion of the package 3 .

[0084] Fig. 9 The upper part of the frame according to this second embodiment is shown in section. Since this upper part has of course no rails, the frame 4 is bonded directly to the fixed part 1 via the rubber ring 8 placed in the recess 4b. Only one seal 6c, whose cross section differs greatly from that of the seal 6b, is supported by the frame.

[0085] Thus, on the sides, the rails 5 are glued to the fixing parts, whereas the frame 4 is glued to the fixing parts on its upper part by means of the same rubber rings 8 which circulate in the recesses 5 b, 4 b respectively.

[0086] Recognize the risks of penetration

[0087] The author has recognized that the solution according to this second embodiment, in particular for mounting the frame and the rails, presents many advantages but also significant risks due to the specific structure of the device, more precisely because the frame extends on three sides while the rails extend only on the side edges.

[0088] Fig.10 The dashed line shows area 41 where this risk is recognized. Fig.11 1 (a view without the moving plate and seal) and 12 (a view of the frame and rails only). Fig.12 As shown, the rubber ring 8 is assembled into the frame 4 along the bearing surface 61 of the rubber ring on the frame, in the upper part of the frame, and in the track 5 along the bearing surface 62 of the rubber ring on the track. When the track 5 supports the frame 4, a discontinuity 63 appears between the two bearing surfaces 61 and 62, and there may be a gap due to installation tolerances.

[0089] like Fig.13 , 14 As shown by the dashed arrows in 15 , at the discontinuity 63 between the frame 4 and the rail 5 , there is a risk of water penetrating into the interior of the vehicle.

[0090] The recognition of this problem is not obvious, since the presence of the seal 6 would normally appear sufficient to a person skilled in the art, and the recognition of this problem led the authors of the method to conduct an in-depth analysis, and they therefore proposed implementation means for controlling the seal at this discontinuity 63.

[0091] Four examples of controlled sealing are described below, which can of course be combined.

[0092] First Sealing Solutions

[0093] according to Fig.16 The first method shown proposes adding a second lip 101 to the seal 6, which generally comprises at least one lip 102 arranged to come into contact with the mobile plate 2, more precisely with the package 3 supported by it. In practice, it is conventional to provide one or more lips 102 cooperating with the mobile plate. The present disclosure also provides at least one lip 101 extending along the attachment portion of the track (in this embodiment) to the fixed part to come into contact with the fixed part on its side edge on the sealing profile. Thus, this lip reduces Fig.14 Penetration shown.

[0094] Second sealing solution

[0095] according to Fig.17A and 17BIn the second solution shown, before depositing the main rubber ring, a rubber ring or seal 111 is placed (different from the subsequent support surfaces 61 and 62 ( Fig.12 ) receives the main rubber ring 8), which can be a rubber ring or a suitable sealant. Again, this makes it possible to effectively reduce penetration.

[0096] Third Sealing Solution

[0097] according to Fig.18 In the third solution shown, the joining zone 121 forming the discontinuity is inclined, the portion facing outwards (towards the opening in the fixing part) being lower than the portion facing inwards and forming an angle of 25° or more.

[0098] Fourth sealing solution

[0099] according to Figures 19 to 21 The fourth solution shown implements a cover or curling between the rail 5 and the frame 4 so that the discontinuity on the outside (towards the opening) is lower than on the inside. Thus, the inner water outlet area 131 is higher than the outer water inlet area 132. The dashed line 133 shows the outer limit of the rubber ring 8.

[0100] Such a cover can have a substantially arc-shaped concave shape on the side facing outwards, thereby facilitating the drainage of water.

[0101] Fig. 20 and 21 The solution is shown in two partial perspective views, without moving plates and without seals. Fig. 20 As can be seen from the dashed arrows, the water that infiltrates and rises by capillary action is discharged along the track before reaching the apex.

[0102] Blocking the bottom of the moving plate – first solution

[0103] Since the moving plate 2 is guided by two pads 7 located on top of it, Fig. 22 As shown, due to the flexibility of the guide, in particular during installation, its base may be unintentionally moved along the X (arrow F1 ) and Y (arrow F2 ) axes before the window lifting mechanism is attached.

[0104] In order to prevent or at least reduce these unintentional movements along X and Y, one or two stops 161 formed in or fixed to the bottom of the frame or rail (below the lower level of the fixed part) may be provided. In particular, these stops may be directly integrated into the frame 4, at least on one side of the frame, such as Fig.23A and 23B As shown,.

[0105] Blocking the bottom of the moving plate – second solution

[0106] like Figure 24 to Figure 27 As shown, when the mobile plate 4 supports the package, it can also directly integrate one or two stops 35, 36, cooperating with the rails and / or the frame.

[0107] Fig.24 An overall view of the device is shown, wherein the portion of the device surrounded by a dotted line is Fig.25 The mobile plate enclosure 3 has a stop 35 cooperating with an additional element 45 integral with the fixed part, in particular with the lower part 411 of the frame, wherein a central crosspiece connects the two sides of the frame or rails or attachments on the frame.

[0108] from Fig.26 As can be seen in section AA, the blocking of the fixing plate along the Y axis is ensured by a groove 351 formed in the stop 35 which cooperates with a portion 451 of the fixing part which penetrates into the groove.

[0109] The moving plate is blocked along the X axis by Fig. 27 The interface BB is shown. The stopper 351 formed in the package is held in the fixing part 451.
