Abstract
Description
Technical Field
[0001] This invention relates to a system for closing an opening in the body of a vehicle, particularly a motor vehicle, by means of a glass window. The glass window includes a window and means for translating between a position at least partially retracted relative to the opening and a position closing the opening of the body. The window is curved and laminated, and includes at least one outer glass sheet, an inner glass sheet, and an intermediate layer located between the outer and inner glass sheets. Background Technology
[0002] This invention is particularly applicable to frameless vehicle door openings defined between the upper body edge and the two lateral body edges of the vehicle, and the portion adjacent to the door (referred to as the "window opening of the body") when the door is closed.
[0003] In these arrangements, in the closed position, the glass windows are held in this position by the doors at the top and sides, or even not at all, but rather by being held in this position directly on the body within the window opening of the body.
[0004] European patent application No. EP 1 178 175 is also known from the prior art, which relates to a system for positioning and assembling windows that attempts to solve the problem of maintaining windows. The solution proposed in this document is cumbersome to implement and results in time loss, which is too long for motor vehicle manufacturers seeking to assemble their vehicles as quickly as possible.
[0005] Patent applications GB 2515525 and WO 2022 / 140991, which have multi-part seals, are also known from the prior art.
[0006] Finally, a movable glass window structure is known from document FR 3 058 097, which is simultaneously lightweight, robust, effective, easy to manufacture, and easy to implement. For this purpose, the glass window particularly comprises a window with a thin inner glass sheet (at most between 0.4 and 2.10 mm), and its edges are covered with a protective layer extending along its entire length, the edges of the inner sheet being outside the edges of the plastic sheet and the outer glass sheet.
[0007] A protective layer can contribute to the aesthetics of a window, even though its primary purpose is to ensure safe contact with the edges of the thin inner glass sheet.
[0008] However, what is considered aesthetically pleasing to some may be unattractive to others: the present invention proposes a novel construction that does not require a protective layer and relates to a system comprising a window with an inner glass sheet having a cantilever relative to an outer sheet and an intermediate layer, which provides both a security solution and a satisfactory response to the window in terms of mechanical strength and acoustic performance acceptable to vehicle manufacturers. Summary of the Invention
[0009] Therefore, the present invention relates to a system for closing an opening in the body of a vehicle, particularly a motor vehicle, according to claim 1. The system includes a glass window comprising a window and a means for vertically translating the window relative to the body of the vehicle between a position for closing the opening through the window and a retracted position of the window, or vice versa. The window is curved and laminated, and includes at least one outer glass sheet, an inner glass sheet, and at least one plastic intermediate layer between the outer and inner glass sheets, each layer having a peripheral edge. The edge of the inner glass sheet forms a cantilevered portion of the upper edge of the window in the upper portion of the glass window, the cantilevered portion projecting relative to the edges of the intermediate layer and the outer glass sheet. The opening is defined at least in the upper portion by the upper edge of the body.
[0010] A significant feature of the system according to the invention is that it includes a seal in the upper portion of the window, the seal including a recessed portion opening at the bottom and capable of receiving a cantilever portion of the inner glass sheet in the closed position, the seal including a lateral protrusion, the edges of the intermediate layer and the outer glass sheet contacting the lateral protrusion in the closed position, such that the lateral protrusion is flush with the surface of the body near the edge of the upper body and flush with the outer surface of the outer glass sheet in the closed position, and wherein, in the closed position, the lateral protrusion of the seal extends in height between the upper body edge of the intermediate layer and the edge of the outer glass sheet, such that the ratio of the sum of the height of the cantilever portion and the height of the lateral protrusion to the sum of the thicknesses of the outer glass sheet and the inner glass sheet is equal to or less than 3.0, preferably between 1.0 and 2.90 (inclusive), or between 1.0 and 2.5 (inclusive).
[0011] Therefore, the recessed portion of the seal can accommodate the cantilever of the inner glass sheet in the closed position, but not the edge of the intermediate layer and the edge of the outer glass sheet.
[0012] Therefore, the present invention proposes a novel construction for cooperation between a window and its environment, which reduces the externally visible thickness of the seal that is necessarily present at the closed position between the window and the body.
[0013] This involves providing specific dimensions for the cantilever and lateral protrusions based on the rigid thickness (the thickness of the outer and inner glass sheets) to achieve high sealing performance while providing a compact system that is virtually invisible from the outside of the vehicle.
[0014] Preferably, the sum of the height of the cantilever and the height of the protrusion is between 5.0 mm and 10.0 mm; for example, it is 7.5 ± 2.5 mm.
[0015] Preferably, the sum of the thicknesses of the outer glass sheet and the inner glass sheet is less than 5.0 mm.
[0016] In the following text, the cantilever will also be referred to as the “internal cantilever” because it involves making the inner glass sheet larger than the outer glass sheet; in other words, only when the inner glass sheet is fully within the nominal size (the size of the window opening to be closed).
[0017] The width of the inner cantilever is the distance between the plane perpendicular to the edge of the outer glass sheet and the plane perpendicular to the edge of the inner glass sheet.
[0018] To facilitate lamination, it is preferable that the intermediate layer and the outer glass sheet are the same size (or substantially the same size), such that the edges of the outer glass sheet and the intermediate layer are at the same level throughout the window.
[0019] The present invention makes it possible to provide a window with a single internal cantilever that is not visible to the vehicle user, the cantilever preferably extending along the upper edge of the window and embedded in a seal attached to the edge of the body (the upper edge defining the opening) at the location for closing the window.
[0020] Preferably, the window comprises only two glass sheets: the outer glass sheet and the inner glass sheet.
[0021] Preferably, the protruding end is exposed; it is not covered by any protective layer, seal, or sealing element.
[0022] Preferably, the lateral protrusion is located next to the recess, further outward.
[0023] Preferably, regardless of the window's position, the lateral protrusion is permanently flush with the surface of the body near the edge of the upper body, and is flush with the outer surface of the outer glass sheet only when the window is closed.
[0024] The system according to the invention may also include, individually or in combination, the following features: - The cantilever portion of the inner glass sheet protrudes at a height of at least 5.0 mm, particularly between 5.0 mm and 20.0 mm, or between 8.0 mm and 18.0 mm, relative to the edges of the intermediate layer and the outer glass sheet. - The cantilever portion of the inner glass sheet protrudes at a height of up to 9.0 mm, particularly between 4.0 mm and 9.0 mm, or between 5.0 mm and 9.0 mm, or between 5.0 mm and 8.0 mm, relative to the edges of the intermediate layer and the outer glass sheet. - The inner glass sheet has a thickness of at least 2.85 mm, particularly between 2.85 mm and 4.0 mm, and a surface stress greater than 80 MPa. The outer glass sheet has a thickness between 1.0 mm and 2.6 mm, preferably between 1.6 mm and 2.1 mm, and a surface stress between 15 MPa and 50 MPa. - The intermediate layer has a thickness between 0.3 mm and 1.6 mm, preferably between 0.5 mm and 0.9 mm. - The ratio between the thickness of the outer glass sheet and the thickness of the inner glass sheet is between 0.34 and 0.9. - The lateral protrusion of the seal extends at a height of at least 1.0 mm, preferably between 2.0 and 8.0 mm, and more preferably between 2.0 and 5.0 mm, between the edge of the upper body and the edge of the intermediate layer and the outer glass sheet, at the location for closing the glass window. - The inner sealing recess includes an inner wall from which a flexible lip protrudes. This flexible lip is deformable and rests against an inner glass sheet in a position for closing the window. The seal is made of an elastically deformable material, preferably rubber or silicone resin. - The inner glass sheet has a second cantilever that extends at least partially beyond the lower edge of the window, and the second cantilever protrudes into the lower portion of the window relative to the edges of the intermediate layer and the outer glass sheet. - The second cantilever is attached to a retainer for vertical translational movement of the device, which ensures vertical translational movement of the window between the closed position and the retracted position, or vice versa. - The window and the device for vertical translational movement of the window are supported by a vehicle door, which at least partially forms the lower part of the main body.
[0025] The present invention also relates to glass windows for use in systems as described above.
[0026] A glass window includes a window and a device for vertical translational movement of the window. The window is curved and laminated, and includes at least one outer glass sheet, one inner glass sheet, and at least one plastic intermediate layer between the outer and inner glass sheets. Each sheet has a peripheral edge, and the edge of the inner glass sheet forms a cantilevered portion of the upper edge of the window in the upper portion of the glass window, the cantilevered portion projecting relative to the edges of the intermediate layer and the outer glass sheet. According to the invention, a significant feature of the glass window is that the cantilevered portion of the inner glass sheet projectes relative to the edges of the intermediate layer and the outer glass sheet at a height of at most 9.0 mm, particularly between 4.0 mm and 9.0 mm, or between 5.0 mm and 8.0 mm.
[0027] According to embodiments disclosed and illustrated below, the inner glass sheet has a thickness of at least 2.85 mm, particularly between 2.85 mm and 4.0 mm, and a surface stress greater than 80 MPa.
[0028] Additionally, the outer glass sheet may have a thickness between 1.0 mm and 2.6 mm, preferably between 1.6 mm and 2.1 mm, and a surface stress between 15 MPa and 50 MPa.
[0029] Additionally, the intermediate layer may have a thickness between 0.3 mm and 1.6 mm, preferably between 0.5 mm and 0.9 mm.
[0030] Even more preferably, the ratio between the thickness of the outer glass sheet and the thickness of the inner glass sheet is between 0.34 and 0.9.
[0031] In an advantageous embodiment, the inner glass sheet has a second cantilever that extends at least partially along the lower edge of the window and protrudes into the lower portion of the window relative to the edges of the intermediate layer and the outer glass sheet.
[0032] In this embodiment, the second cantilever portion may be attached to the retainer of the moving device, which ensures vertical translational movement of the window between the closed position and the retracted position, or vice versa.
[0033] Preferably, the seal is not part of the glass window. Attached Figure Description
[0034] The invention will be better understood by reading the following detailed description of non-limiting exemplary embodiments and the accompanying drawings: - [ Figure 1This illustration shows a partial vertical sectional view of a glass window in the closed position and the main body edge (defining the upper edge of the system opening) of the system according to the invention. The glass window includes a cantilever in the upper portion. - [ Figure 2 This illustration shows a vertical sectional view of a window retainer, with the cantilevered portion of the glass window inserted into the retainer in the lower part. Detailed Implementation
[0035] Note that, for ease of reading, the proportions between the various elements depicted in the accompanying drawings have not been strictly adhered to.
[0036] In this document, the limits of the range are included in the range when referring to a range.
[0037] The term "edge" or "end face" refers to the narrow edge of a sheet that lies essentially laterally between the two main faces of the sheet. The "lateral projection" of the edge is considered to be in this lateral direction between the main faces of the sheet.
[0038] Figure 1 A cross-sectional view of the upper portion of the right-side window 1 of a vehicle, including the system according to the invention, is shown.
[0039] In particular, the side window 1 of the door (not shown) of the motor vehicle can be moved substantially vertically relative to the door between a retracted position and a closed position. In the retracted position, the window is completely or almost completely inside the door, and in the closed position, the window closes the door opening. Therefore, in the closed position, this window 1 achieves a vertical separation between the interior space I inside the vehicle and the exterior space E outside the vehicle.
[0040] Therefore, in this literature, the concepts of “external” and “internal” are considered for the external space E and the internal space I, respectively.
[0041] exist Figure 1 and Figure 2 In the embodiment shown, the glass window 1 is a single piece. It includes a curved (i.e., non-flat) and laminated window 2. However, for simplicity, in Figure 1 and 2 In the attached diagram, window 2 is considered to be flat.
[0042] The window 2 of the glass window 1 is a laminated window, which includes, from the outside to the inside, at least in this order: an outer glass sheet 3, an intermediate layer 4 made of plastic material, and then an inner glass sheet 5; however, at least one other sheet may be inserted between the outer glass sheet 3 and the plastic intermediate layer 4 or between the plastic intermediate layer 4 and the inner glass sheet 5.
[0043] The outer glass sheet 3 has an outer surface 30 oriented toward the outside E, an intermediate surface 32 oriented toward the plastic intermediate layer 4, and a peripheral edge 31 located between the two surfaces.
[0044] The inner glass sheet 5 has an intermediate surface 50 oriented toward the plastic intermediate layer 4, an inner surface 52 oriented toward the inner I, and a peripheral edge 51 located between the two surfaces.
[0045] The plastic intermediate layer 4 has an outer intermediate layer 40 oriented toward and in contact with the intermediate layer 32, an inner intermediate layer 42 oriented toward and in contact with the intermediate layer 50, and a peripheral edge 41 located between the two intermediate layers 40, 42.
[0046] The outer glass sheet 3 is, for example, a glass sheet that has undergone a hot bending operation before manufacturing the laminated window 2 and has a thickness e3 between 1.0 mm and 2.6 mm, preferably between 1.6 mm and 2.1 mm.
[0047] The plastic interlayer 4 is, for example, a polyvinyl butyral (PVB) film having a thickness e4 between 0.3 mm and 1.6 mm, preferably between 0.5 mm and 0.9 mm. This interlayer 4 can be combined with solar films, absorption films, and can be configured to form a protective filter against ultraviolet, infrared, and other radiation.
[0048] The inner glass sheet 5 is a glass sheet that has been hot-bent and hot-tempered, and has a thickness e5 of at least 2.85 mm. The thickness e5 is particularly between 2.85 mm and 4.0 mm, preferably between 3.10 mm and 3.60 mm, and even more preferably between 3.15 mm and 3.50 mm. For example, the thickness e5 is 3.15 mm.
[0049] In the case where window 2 includes one or more other sheets in addition to the three sheets mentioned above, the inner glass sheet 5 is the innermost sheet of the laminated window.
[0050] like Figure 1 As can be seen, the inner glass sheet 5 has a cantilever portion 53 in the upper part of the window 2, that is, it has a top portion that protrudes beyond the edges 41 and 31 of the intermediate layer 4 and the outer sheet 3 respectively, with the edges 41 and 31 being substantially at the same level.
[0051] In the context of this embodiment, the cantilever portion 53 of the inner glass sheet 5 protrudes at a height H of at least 5.0 mm (or at least substantially 5 mm), particularly between 5.0 mm and 20.0 mm, or between 8.0 mm and 18.0 mm, relative to the edge 41 of the intermediate layer and the edge 31 of the outer glass sheet.
[0052] It is also envisioned that the inner glass sheet 5 has a thickness of at least 2.85 mm and a surface stress greater than 80 MPa. Therefore, the inner glass sheet 5 has undergone heat treatment designed to improve its impact resistance relative to the untreated glass sheet. This is particularly important when the cantilever portion 53 is exposed, i.e., when it is not covered by any protective layer, seal, or sealing element.
[0053] Therefore, the edges of the cantilever portion 53 are not sharp; in addition, the ridge can be smoothed by grinding to further reduce the risk of scratching the skin of the vehicle user during vehicle use.
[0054] The outer glass sheet 3 has a thickness e3 between 1.0 mm and 2.6 mm (or substantially between 1 mm and 2.6 mm), preferably between 1.6 mm and 2.1 mm, and has a surface stress between 15 MPa and 50 MPa. Here, the thickness e3 is, for example, 1.6 mm.
[0055] The intermediate layer 4 has a thickness e4 between 0.3 mm and 1.6 mm (or substantially between 0.3 mm and 1.6 mm), preferably between 0.5 mm and 0.9 mm. Here, the thickness e4 is, for example, 0.76 mm.
[0056] The combination of these dimensions and technical features provides Window 2 with both satisfactory mechanical strength and satisfactory acoustic performance for the comfort and safety of vehicle passengers.
[0057] Specifically, it is envisioned that the ratio between the thickness of the outer glass sheet 3 and the thickness of the inner glass sheet 5 is preferably between 0.34 and 0.9 (or substantially between 0.34 and 0.9) to optimize acoustic performance and safety.
[0058] like Figure 2 As shown, the internal glass sheet 5 also has a cantilever 54 in the lower part of the window 2.
[0059] The cantilever portion 54 preferably has the same height H as the cantilever portion 53 in the upper part of the window 2.
[0060] It should be noted that window 2 has no cantilever on its left and right lateral edges, so that the window can slide during vertical translational movement between its closed position and its retracted position, or vice versa.
[0061] As in Figure 2As can be seen, in addition to window 2, glass window 1 also includes a device 6 for vertical translational movement along at least a portion of at least one bottom edge, for allowing window 2 to translate relative to the vehicle door. Within the meaning of the invention, the device 6 for vertical translational movement may include one or more holes partially or completely passing through the window (i.e., on a portion of the thickness of the element forming it or on the entire thickness of the element or on a portion of the thickness of the window including several elements at this location, or even on the entirety of the window), one or more retainers, one or more mounting grooves, one or more tracks or slides.
[0062] In this case, the retainer is a window retainer, which has, for example, a roughly inverted h-shaped cross-section and no holes in the window.
[0063] The window retainer is supported in the lower part of the window by the cantilever 54, and only by the cantilever 54, which allows for the production of more compact glass windows.
[0064] Therefore, the window retainer has: a first part consisting of two parallel walls 63, 64 connected at their bases to form a longitudinal groove, i.e., forming a U-shaped cross-section; and a second part consisting of a tail 65 extending opposite to the bases connecting these walls and opposite to the parallel walls 63, 64.
[0065] In the illustrated version, assembly is performed such that the h-shaped parallel walls 63, 64 snap onto the lower portion of the window 2, and then the tail 65 is positioned to extend substantially from the window 2.
[0066] This h-shape of the window retainer is particularly advantageous because it allows force to be transferred between the window retainer and the window based on the large area of the sum of the inner surfaces corresponding to the parallel walls 63, 64; however, a single plate can be used, which, for example, has at least two parts: a first part for interacting with the window and a second part for interacting with the mechanism for raising / lowering the window.
[0067] exist Figure 2 In the design, window 2 is curved, while parallel walls 63, 64 and tail 65 are planar; however, parallel walls 63, 64 and / or tail 65 may be curved. Tail 65 extends generally from the midpoint of the base connecting parallel walls 63, 64, but tail 65 may also be positioned to extend from either parallel wall 63, 64.
[0068] exist Figure 2 In the middle, the tail 65 is not parallel to the walls 63 and 64. When the glass window 1 is correctly positioned relative to the window retainer, axis A represents the mid-plane of the glass window 1 at its lower end, and the tail 65 is oriented at a non-zero angle relative to axis A, which is a function of the curvature of the window 2.
[0069] The rear section 65 is intended to connect to a motor drive system (not shown) to allow the glass window 1 to be raised and lowered in the vehicle's doorway.
[0070] The engagement of the window retainer with window 2 is performed on a template, thereby allowing control over tolerances on the window retainer / window 2 assembly.
[0071] According to the invention, in addition to the glass window 1 (i.e., the glass window 2 disclosed above and at least one window retainer), the system according to the invention includes other elements that will now be disclosed: First of all, Figure 1 As can be seen, the system includes an upper edge 71 of the body 7, which defines an opening disposed in the body. In fact, the system for closing the opening is configured such that the outer surface 30 of the outer glass sheet 3 of the window 2 is indirectly flush with the outer surface 70 of the wall of the body 7 at the level of the upper edge 71, which defines the opening closed by the glass window (in the closed position). It is indirectly flush because a sealing portion exists between the upper edge 71 and the outer surface 30, and this sealing portion is flush with both the upper edge 71 and the outer surface 30.
[0072] As can be seen, behind the upper edge 71, the body has an inverted U-shaped metal sheet profile 72, which has two side walls 73 and 74 connected by a top wall 75. One of the walls of this profile is attached to the upper body edge 71 by pressing a metal sheet folded thereon.
[0073] As in Figure 1 As can be seen, contour 72 accommodates seal 8, which includes the system according to the invention, and seal 8 at least partially covers the upper edge 71 of body 7. As is typically the case, this seal 8... Figure 1 The window is shown in a "static" position, that is, when the window is not in the closed position, so as to illustrate the outline of its creation.
[0074] The seal 8 includes an inner recess 80 that is able to receive the cantilever portion 53 of the window 2 in the closed position; this inner recess 80 only receives the cantilever portion 53; it does not receive the edge (or edge) of the intermediate layer 4, nor the edge (or edge) of the outer glass sheet 3.
[0075] As can be seen, the seal 8 has a lateral protrusion 81 that covers a portion of the upper body edge 71 (which is the outermost part of the edge 71).
[0076] The lateral protrusion 81 of the seal is also part of the seal. When the window 2 is in the closed position, the edges 41 and 31 of the intermediate layer 4 and the outer glass sheet 3 are positioned against this part of the seal. Therefore, in the position for closing the window, the lateral protrusion 81 of the seal 8 is flush with the upper body edge 71, the outer surface 70 of the body, and the outer surface 30 of the outer glass sheet 3 of the window 2, ensuring continuity between the outer surface 70 and the surface 30. Thus, when the window 2 is in the closed position, the system gives the impression that the outer surface of the window is a protrusion of the body 7; when the window 2 is not in the closed position, the lateral protrusion 81 of the seal 8 is flush with and remains flush with the outer surface 70 of the body.
[0077] It is conceivable that the lateral protrusion 81 of the seal 8 extends at a height w of at least 1.0 mm, preferably between 2.0 and 8.0 mm, and more preferably between 2.0 and 5.0 mm, between the upper body edge 71 and the edges 41 and 31 of the intermediate layer 4 and the outer glass sheet 3, at the location for closing the glass window. The low height reduces air turbulence during vehicle operation.
[0078] The ratio of the sum of the height H of the cantilever 53 and the height w of the lateral protrusion 81 to the sum of the thickness e3 of the outer glass sheet 3 and the thickness e5 of the inner glass sheet 5 is equal to or less than 3.0, preferably between 1.0 and 2.90 (inclusive), or between 1.0 and 2.5 (inclusive). This combination of dimensions and technical features provides the window 2 and the closing system with both satisfactory mechanical strength and satisfactory acoustic performance for the comfort and safety of vehicle passengers, while being aesthetically discrete, i.e., almost invisible from the outside of the vehicle.
[0079] To ensure good sound insulation, the recessed portion 80 of the seal 8 includes an inner wall 82, and a flexible lip 83 protrudes from the inner wall 82. The flexible lip 83 is deformable and rests against the inner glass sheet 5, and in particular against the surfaces 50 and 52 of the plate 5 and the cantilever portion 53 in the position for closing the window.
[0080] Considering the same direction, the depth of the concave portion 80 is essentially equal to the sum of the height H of the cantilever portion 53 and the height w of the lateral protrusion.
[0081] To achieve this deformation, the seal 8 is made of a material that can be elastically deformed, such as rubber or silicone.
[0082] The seal 8 is held in the body profile 72 by bonding rather than by simple insertion.
[0083] One wall 82 of the seal may have an outwardly curved end (see...) Figure 1This extends across the side walls of profile 72. This also helps to retain the seal 8 within profile 72 of the body 7. The protruding boss 76 can also serve as an abutment for removing the seal 8 from profile 72.
[0084] The invention has been described by way of example in the preceding text. Of course, those skilled in the art will be able to make various modifications to the invention without departing from the scope of the patent as defined by the claims.
