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 shell and to cover an opening in the fixing part that defines 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 and therefore minimize the size of the attachment parts on the fixing part (rail, frame, etc.) while ensuring, among other things, the guidance, sealing (including in the presence of high-pressure jets) and safety of the movable plate effectively, reliably and durably.

[0010] Another important aspect is the ease of assembly and installation of the device, in particular the moving plate, both during first installation and for maintenance operations, when the fixing parts are fixed to the inner door casing. Utility Model Content

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

[0012] More precisely, in at least one embodiment, an object of the present disclosure is to provide a glass device for producing vehicle doors that is easy to realize and assemble, for example, on an assembly line.

[0013] According to at least one embodiment, another object of the present disclosure is to provide a glass device that can be easily maintained during its installation or when replacing a moving panel, such as after an accident.

[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 vehicle door or body element, the glass arrangement comprising a glass fixing part and a movable glass plate 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 plate being guided along a track supported by the fixing part.

[0015] According to the present disclosure, the mobile plate supports an overmolding obtained by packaging, the overmolding covers the edge of the mobile plate and extends on at least one edge of the surface of the mobile plate facing the interior of the vehicle, the lower part of the overmolding extends on the lower edge of the mobile plate and has at least one stopper capable of cooperating with a frame, a center beam and / or an attachment part on a guide rail supported by the fixed component, the stopper ensuring that at least when the mobile plate is mounted on the fixed component, the movement of the mobile plate relative to the fixed component in two directions substantially perpendicular to the substantially vertical axis is limited.

[0016] In practice, the flexibility of the rails should be taken into account, in particular before the mobile plate is fixed to the window lift, to which the rails are usually fixed in the lower part, the latter supporting the track pads at the upper part. The mobile plate can thus be moved along X (depending on the length of the vehicle) and / or along Y (depending on the width of the vehicle). In order to control this, according to the present disclosure, one or two stops are formed directly in the overmoulding, also referred to as encapsulation in the following, so as to provide simple and effective means for guiding and / or holding the installation of the mobile plate and, where applicable, for maintenance operations.

[0017] According to one embodiment, the enclosure comprises two stops extending close to the rail and / or the frame.

[0018] In particular, the stop may cooperate with a recess formed in the attachment part on the frame, the crossbeam and / or the guide rail.

[0019] This method is easy to implement and effective.

[0020] According to certain aspects, the lower portion of the enclosure may further include elements for connection to a window lifting mechanism.

[0021] Thus, fixing to the window regulator is facilitated and no special attachment parts are required.

[0022] In particular, the connecting element can have at least one hole for fastening the connecting element to the window lifting mechanism. The hole advantageously has a flexible adjustment portion.

[0023] According to another particular aspect, the lower part of the enclosure may be extended by two side parts, each supporting a pad able to slide in one of the rails, or a pad support receiving said pad.

[0024] Again, this makes it possible to simplify the manufacture and installation of the device, with the encapsulation being performed in a single operation and ensuring a plurality of different functions.

[0025] According to a particular embodiment, the pads have a substantially C-shaped cross section, a first end of the pad engaging in the side of the enclosure and a second end of the pad supporting a guide element in the track extending substantially above the first end.

[0026] This C-shaped cross-section can reduce the overall size of the pad.

[0027] According to another particular embodiment, the pads have a substantially S-shaped cross-section, with a first end of the pad engaging in the side of the package and a second end of the pad supporting a guide element in the track, which extends beyond the edge of the mobile plate and over a corresponding edge of the fixed part.

[0028] This approach, in combination with suitable rails, also allows for a reduction in size and thus an optimisation of the transparent opening.

[0029] According to another particular aspect, the package cross-section has, on at least one of its edges, an extension extending toward the outside of the mobile plate and toward the inside of the vehicle.

[0030] This makes it possible, where applicable, to optimise the management of sealing and drainage by combining with other elements such as seals.

[0031] According to another specific aspect, the package has an upper portion connected to the side portions so as to extend around the entire periphery of the moving plate.

[0032] Of course, the various specific aspects described above may be combined in whole or in part to optimize the use of the package.

[0033] The present disclosure also relates to a motor vehicle comprising at least one glazing arrangement as described above.

[0034] 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

[0052] Overall structure

[0053] The present disclosure therefore relates to a new technology for manufacturing and / or maintaining glass arrangements for fixed parts of doors (side doors, rear doors, tailgates, hatches, etc.) or even of motor vehicle bodies. The glass or the mobile panel is aligned with at least one edge of the body and mounted flush, that is to say, 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 an equivalent body element).

[0054] 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.

[0055] 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.

[0056] 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.

[0057] The mobile plate 2 receives an encapsulation 3 extending on one or more edges of the mobile plate, as will be shown below according to various embodiments. Such an encapsulation 3 may extend in particular on the edge of the mobile plate and its periphery, extending a few millimeters or centimeters on the face facing the interior of the vehicle, such as Figure 5 and Figure 8 As shown, this will be explained below.

[0058] 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 2 As shown, the frame and / or rails extend below the fixed components 1 (components 411 and 421).

[0059] The seal 6 is installed in the frame 4 along the side and upper portion thereof.

[0060] 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.

[0061] 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.

[0062] Installing Tracks and Frame – Step 1

[0063] 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.

[0064] According to this method, the frame 4 is bonded to the fixing part 1 by means of rubber rings 8 fitted in recesses 4a provided for this purpose. The frame 4 supports a guide rail 5 whose guide portion 5a is able to cooperate with a substantially spherical portion 7a of a pad 7.

[0065] 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.

[0066] 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.

[0067] 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.

[0068] 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).

[0069] 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.

[0070] According to this embodiment, the frame is bonded to the fixing part around its entire periphery.

[0071] Installing the Tracks and Frame - Method 2

[0072] 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.

[0073] 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.

[0074] 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.

[0075] 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.

[0076] 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.

[0077] 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 .

[0078] 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 4a. Only one seal 6c, whose cross section is very different from that of the seal 6b, is supported by the frame.

[0079] 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 5a, 4b respectively.

[0080] Block the bottom of the moving plate

[0081] Since the moving plate 2 is guided by two pads 7 located on top of it, Fig.10 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.

[0082] To prevent or at least reduce these unintentional movements along X and Y, one or two stops may be provided.

[0083] like Figures 11 to 14 As shown, the packaging of the mobile plate 3 directly integrates one or two stops 35 , 36 , cooperating with the rails and / or the frame.

[0084] Fig.11 An overall view of the device is shown, wherein the components supporting the stopper 35 are shown in Fig.12 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.

[0085] from Fig.13 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.

[0086] The moving plate is blocked along the X axis by Fig.14 The interface BB is shown. The stopper 351 formed in the package is held in the fixing part 451.

[0087] Connecting to window regulators

[0088] Fig.15 A moving plate with two stops 35 , 36 is shown.

[0089] like Fig.16 As shown, the bottom package can further integrate means 91, 92 for connecting to a window lifter (not shown). Here, these connecting means comprise two protrusions, each with a hole 911, 921. Of course, it could also involve a single element with two holes.

[0090] These holes 911, 921 can be fixed to the window lifter, for example by screwing.In order to compensate for any installation play, the holes can receive a flexible intermediate part.

[0091] Pad Encapsulation

[0092] like Fig.17 As shown, the encapsulation can also extend on the side edge of the moving plate. In this case, the encapsulation can support the pad 7 that slides in the track 5, or support the pad support that can receive the pad itself.

[0093] Already explained Figure 8 An example of a cross section of a side edge of a device is shown.

[0094] Encapsulation of the entire perimeter of the mobile board

[0095] In addition to the lower and side portions, the package may also extend along the upper portion of the fixing plate, e.g. Fig.18 In this case, the package can extend around the entire perimeter of the mobile board by integrating all or part of the above-mentioned functionalities, where applicable.

[0096] Fig. 9 (illustrated) is an example of a cross section of the device along the upper edge. Figure 8 ) Reducing the width of the package 3, as well as the width of the frame 4, which holds the seal 6 by its two edges, makes it possible to improve the clear opening.
