Description

[Technical field]

[0001] The present invention relates to decorative glass panels, and more particularly to decorative glass panels that are particularly advantageous for automotive applications as interior vehicle glass, allowing for backlighting or illumination through the edges while meeting safety constraints. [Background technology]

[0002] Decorative glass panels are needed in the automotive market, especially in the luxury car segment. Decorative plastic panels are considered to be of low quality, especially from an aesthetic point of view. In addition, plastic is very sensitive to impacts and scratches compared to glass. Furthermore, plastics usually yellow with age, whereas glass maintains its optical quality for many years.

[0003] In addition, a decorative glass panel must meet two opposing demands: it must be durable and lightweight. The demand for durability tends towards thick glass sheets. However, such thick glass sheets are usually very heavy and increase the total weight of the vehicle. Therefore, there is a tendency to choose thin glass sheets, but in that case, security requirements are faced. In fact, if a decorative glass panel is installed in a vehicle and is broken, the safety of passengers against glass fragments must be ensured. The use of a safety film, which is usually a plastic layer placed adjacent to the glass panel to hold the glass fragments in case of breakage, would further increase the cost of the decorative panel, since an additional element would be used and the integration into the vehicle would be more complicated. Therefore, another option is to use tempered glass, which is strengthened either by thermal or chemical strengthening.

[0004] The automotive industry is looking for decorative glass panels that allow for further illumination. Decorative glass panels are usually made by gluing a glass sheet to a carrier. WO2020178383A1 describes a method for producing decorative panels by injecting a soft material between the glass sheet and the carrier. This document shows an example of edge illumination. However, such integration through the edge of the glass sheet often results in light contamination in the entire decorative glass panel, while car manufacturers are looking for a sharp and seamless design where light is present only in a portion of the decorative glass panel.

[0005] There is therefore a need for decorative glass panels that allow more flexibility in terms of lighting integration whilst ensuring compatibility with security requirements and industrial processes. Summary of the Invention

[0006] The present invention relates to a decorative panel for the interior of a vehicle. Such a decorative panel comprises a carrier adapted to fix the decorative panel to a vehicle. The decorative panel further comprises a glass sheet having an inner surface and an outer surface. The decorative panel further comprises an adhesive layer. The adhesive layer is disposed between the carrier and the inner surface of the glass sheet. The adhesive layer integrally covers the inner surface of the glass sheet. The luminous transmittance of the adhesive layer is at least 1%, preferably at least 5%, more preferably at least 10%, and even more preferably at least 50%.

[0007] The invention also relates to the use of such a decorative panel in combination with a light source.

[0008] The invention further relates to a method for producing such a decorative panel. [Brief description of the drawings]

[0014] The present invention will be described with respect to particular embodiments and with reference to certain drawings but the invention is not limited thereto but only by the claims.

[0015] As will be appreciated by those skilled in the art, some embodiments described herein include some features and not others that are included in other embodiments, but combinations of features from different embodiments are within the scope of the invention and form different embodiments. For example, in the following claims, any of the claimed embodiments may be used in any combination.

[0016] The present invention proposes a decorative panel for the interior of a vehicle. The decorative panel according to the invention is attached to any part of the interior of a vehicle to provide better aesthetics or to fix or protect parts of the interior of the vehicle. Such decorative panels are attached to cover (fully or partially) the door, the contour of the door handle, parts of the dashboard or the center console (center console means the console between the front seats, which may extend towards the dashboard), the back of the seat (including the back of the headrest), the roof, the armrest, etc. Vehicle refers to any kind of vehicle, such as (but not limited to) cars, vans, trucks, motorcycles, buses, trams, trains, drones, planes, helicopters, etc.

[0017] Decorative panels include carriers adapted to fasten trim elements to the interior of a vehicle. Such carriers are usually manufactured from materials selected from thermoplastics, such as polybutylene terephthalate (PBT), polycarbonate-acrylonitrile butadiene styrene (PC-ABS), polyamide (PA6), polyamide copolymer (PA66), polyoxymethylene (POM), polypropylene (PP), thermoplastic elastomers (TPE) or thermosetting materials, such as polyurethane (PUR), epoxy (EP), with or without fillers that provide additional properties, such as glass fibers for mechanical reinforcement. Carriers can also be manufactured from metal materials (thixomolded), such as zamak, aluminum, magnesium. Carrier plates can be manufactured from fiber-reinforced plastic, talc-reinforced plastic, glass bead-reinforced plastic. Carriers can also be manufactured from glass, ceramic, stone, marble, wood or other materials suitable for the manufacture of carriers.

[0018] The decorative panel further comprises a glass sheet having an outer surface and an inner surface. The inner surface refers to the surface facing the carrier, and the outer surface refers to the opposite surface. The composition of the glass sheet is not particularly limited. The glass sheet may be soda-lime silicate glass, aluminosilicate glass, alkali-free glass, borosilicate glass, etc. Preferably, the glass sheet of the present invention is made of soda-lime glass or aluminosilicate glass. The glass sheet according to the present invention may be a glass sheet obtained by the float process, the drawing process, the rolling process or any other process known for producing glass sheets from molten glass compositions. According to a preferred embodiment according to the present invention, the glass sheet is a float glass sheet. The term "float glass sheet" is understood to mean a glass sheet formed by the float glass process, which includes flowing molten glass on a bath of molten tin under reducing conditions. The glass sheet preferably has a thickness of 0.5 mm to 2.1 mm.

[0019] According to an embodiment of the invention, the glass sheet has a composition comprising, in contents expressed as a percentage of the total weight of the glass: SiO255~85% Al2O30-30% B2O30~20% Na2O 0~25% CaO 0~20% MgO 0~15% K2O 0~20% BaO 0-20%.

[0020] In a preferred embodiment, the glass sheet has a composition comprising, in contents expressed as a percentage of the total weight of the glass: SiO255~70% Al2O30-25% B2O30-10% Na2O 5~20% CaO 0~5% MgO 0~15% K2O 0~10% BaO 0-5%.

[0021] In a more preferred embodiment, the glass sheet has a composition comprising, in contents expressed as a percentage of the total weight of the glass: SiO260~70% Al2O35-20% B2O30~5% CaO 0~3% MgO 0~10% Na2O 10~20% K2O 0~5% BaO 0-5%.

[0022] In a more preferred embodiment, the glass sheet has a composition comprising, in contents expressed as a percentage of the total weight of the glass: SiO265~70% Al2O3 4-8% B2O30-1% CaO 0~2% MgO 7~12% Na2O 14~18% K2O 0~2% BaO 0-1%. Such a composition represents a good compromise between the mechanical performance of the glass after chemical strengthening and cost optimization.

[0023] In a more preferred embodiment, the glass sheet has a composition comprising, in contents expressed as a percentage of the total weight of the glass: SiO265~75% Al2O30-3% B2O30-1% CaO 5~10% MgO 4~8% Na2O 10~15% K2O 0~1% BaO 0-1%.

[0024] The decorative panel further comprises an adhesive layer, the adhesive layer being disposed between the carrier and the inner surface of the glass sheet. The adhesive layer integrally covers the inner surface of the glass sheet. The adhesive layer integrally covering the inner surface of the glass sheet can increase safety for vehicle occupants in case of glass sheet breakage. In fact, the adhesive layer can prevent the glass sheet pieces from scattering in case of glass sheet breakage, since the adhesive layer adheres the glass sheet pieces to the carrier.

[0025] The adhesive layer is required to be transparent or semi-transparent to visible light. Visible light means light corresponding to the visible wavelength range, which is included in the range of 380 nm to 780 nm. In this specification, the total light transmittance using a light source D65 (LTD) at an observation solid angle of 2° is considered to quantify the luminous transmittance (according to the ISO9050 standard). The luminous transmittance represents the proportion of the radiant flux of wavelengths of 380 nm to 780 nm that is transmitted through the adhesive layer. By transparent or semi-transparent, it is understood that the adhesive layer has a luminous transmittance of at least 1%. The luminous transmittance of the adhesive layer can be at least 3%, 5%, 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90%, 95%, or 99%.

[0026] In a preferred embodiment, the inner surface of the glass sheet is at least partially coated with an opaque layer having a luminous transmittance of less than 1%. To quantify the luminous transmittance, the total light transmittance with illuminant D65 (LTD) at an observation solid angle of 2° is considered (according to the ISO 9050 standard). The luminous transmittance represents the percentage of the radiant flux of wavelengths between 380 nm and 780 nm that is transmitted through the opaque layer. Such an opaque layer can be an ink layer, a lacquer, an enamel, a paint, a layer deposited by plasma deposition. Such an opaque layer can be deposited on the glass sheet by any method known in the art. Non-limiting examples of deposition processes for decoration include silk screen printing, inkjet printing, laser printing or screen printing methods. The preferred method is silk screen printing, mainly due to its ability to generate high quality colored patterns, its flexibility and its fast deposition rate. Inkjet printing is also a preferred method due to its great flexibility in terms of design. A combination of silk screen printing and inkjet printing can also be used to exploit the advantages of both techniques. Other deposition methods include spraying or curtain coater techniques. Alternatively, the opaque layer can be a polymeric film, in which case it is deposited by a conventional lamination process.

[0027] In a preferred embodiment, the carrier includes at least one hole adapted to pass visible light through the carrier. Additionally, no opaque layer is applied to the inner surface of the glass sheet at least where the inner surface of the glass sheet coincides with the at least one hole in the carrier. The area of ​​the glass sheet that coincides with the at least one hole in the carrier may be covered with a transparent or semi-transparent layer. By transparent or semi-transparent, it is understood that the layer has a luminous transmittance of at least 1%. The luminous transmittance of this layer may be at least 3%, 5%, 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90%, 95%, 99%. This transparent or semi-transparent layer may be an ink layer, a lacquer, an enamel, a paint, a layer deposited by plasma deposition. Such a transparent or semi-transparent layer may be deposited on the glass sheet by any method known in the art. Non-limiting examples of deposition processes for decoration include silk screen printing, inkjet printing, laser printing or screen printing methods. The preferred method is silk screen printing, mainly because it can produce high quality colored patterns, is flexible, and has a fast deposition rate. Other deposition methods include spray or curtain coater techniques. Alternatively, the transparent or semi-transparent layer can be a polymeric film, which is then deposited by a conventional lamination process.

[0028] In a preferred embodiment, the inner surface of the glass sheet is at least partially coated with a translucent or transparent layer having a luminous transmittance of at least 1%. The luminous transmittance of this layer may be at least 3%, 5%, 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90%, 95%, 99%. To quantify the luminous transmittance, the total light transmittance with illuminant D65 (LTD) at an observation solid angle of 2° is considered (according to the ISO 9050 standard). The luminous transmittance represents the proportion of the radiant flux of light with wavelengths between 380 nm and 780 nm that is transmitted through the translucent or transparent layer. Such a translucent or transparent layer may be an ink layer, a lacquer, an enamel, a paint, a layer deposited by plasma deposition. Such a translucent or transparent layer may be deposited on the glass sheet by any method known in the art. Non-limiting examples of deposition processes for decoration include silk screen printing, inkjet printing, laser printing or screen printing methods. The preferred method is silk screen printing, mainly due to its ability to produce high quality colored patterns, its flexibility and its fast deposition rate. Inkjet printing is also a preferred method due to its great flexibility in terms of design. A combination of silk screen printing and inkjet printing can also be used to take advantage of the advantages of both techniques. Other deposition methods include spray or curtain coater techniques. Alternatively, the translucent or transparent layer can be a polymeric film, which is then deposited by a conventional lamination process.

[0029] In a preferred embodiment, the adhesive layer is adapted to be injection molded between the carrier and the inner surface of the glass sheet. The adhesive layer may be made of a thermoplastic polymer, such as polypropylene, a thermoplastic elastomer (TPE), such as an olefin-based thermoplastic elastomer (TPO), polyurethane, polyamide or soft polyvinyl chloride, silicone or similar material or any material suitable for injection molding.

[0030] Alternatively, the adhesive layer can be attached to the glass by ultrasonic welding, a technique that is cheaper than injection molding.

[0031] In a preferred embodiment, the adhesive layer obtained by injection molding is further applied to at least one edge of the glass sheet. That is, not only is the adhesive layer injected to cover the inner surface of the glass sheet, but the adhesive layer also covers at least one edge of the glass sheet. Such a configuration allows light to pass in the surrounding area of ​​the glass sheet without the glass being contaminated by light leakage (separation of the optical system from the glass). It is also possible to cover the entire glass surface with a unique (opaque) decorative layer. Thus, there is no need to add a semi-transparent layer to hide the light source on the back side of the glass, which allows for cost reduction and easy processing with 100% homogeneity and no constraints on the printing position. Furthermore, such a configuration allows easy integration and the adhesive layer acts as a soft seal in case of possible contact with rigid surrounding parts. This effectively prevents noise generation, for example due to vibration.

[0032] In a preferred embodiment, the glass sheet is chemically strengthened. Chemically strengthened glass allows the glass to be cold bent and thus to be shaped into the desired shape. Chemical strengthening also improves the mechanical resistance of the glass sheet.

[0033] In a preferred embodiment, the inner surface of the glass sheet further comprises a primer. Thus, the primer is applied to the inner surface of the glass sheet previously at least partially coated with the decoration. The use of such a primer improves the adhesion with the adhesive layer. Such a primer can be, for example, a primer containing silane. Such a primer can alternatively or additionally be applied on the carrier, thus being located between the carrier and the adhesive layer, and can improve the adhesion of the adhesive layer to the carrier.

[0034] In a preferred embodiment, the outer surface of the glass sheet is also decorated with paint, by etching, or with a layer deposited by plasma deposition.

[0035] The invention also proposes the use of a decorative panel as described above in combination with a light source, the decorative panel being fixed to the interior of the vehicle.

[0036] The present invention relates to a method for manufacturing a decorative panel for the interior of a vehicle, comprising the steps of: a) providing a glass sheet having an inner surface and an outer surface; b) providing a carrier adapted to secure a decorative panel to a vehicle; c) injection molding an adhesive layer between the inner surface of the glass sheet and the carrier to completely cover the inner surface of the glass sheet, wherein the luminous transmittance of the adhesive layer is at least 1%, preferably at least 5%, more preferably at least 10%, and even more preferably at least 50%. We also propose a method including:

[0037] The luminous transmittance of this layer can be at least 3%, 5%, 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90%, 95%, 99%.

[0038] The injection molding of the adhesive layer can be carried out, for example, through at least one hole in the carrier, or from the side between the glass sheet and the carrier.

[0039] In a preferred embodiment, the method comprises, after step a, a step a' consisting of at least partially coating the inner surface of the glass sheet with a layer having a luminous transmittance of less than 1%.

[0040] In another embodiment, the method includes, after step a, a step a' consisting of at least partially coating the inner surface of the glass sheet with a layer having a luminous transmittance of at least 1%, which may be at least 3%, 5%, 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90%, 95%, 99%.

[0041] In a preferred embodiment, the method further comprises a step of chemically strengthening the glass sheet prior to step a and potentially step a', and a step b' of cold bending the chemically strengthened glass sheet in a carrier after step b.

[0042] In a preferred embodiment, the method includes the step of coating the inner surface of the glass sheet with a primer prior to step b.

[0043] In a preferred embodiment, an adhesive layer is further applied to the edges of the glass sheet.

[0044] In a preferred embodiment, the carrier is also injection molded. This method is realized as a 2k injection molding process, where the carrier is first injection molded and the adhesive layer is then injection molded. The carrier can further be made of multiple subcomponents. Such a configuration can improve the assembly flexibility. It can also better accommodate thermal expansion constraints.

[0045] Referring to Figure 1a, a decorative panel (1) includes a carrier (10). The carrier is used to secure the decorative panel to the interior of a vehicle (not shown). Here, the carrier is shown having two protrusions (100) for securing the decorative panel (1). Other means for securing such decorative panels are well known to those skilled in the art.

[0046] The decorative panel (1) further includes a glass sheet (30). An inner surface (31) of the glass sheet (30) faces the carrier (10) and an outer surface (32) of the glass sheet (30) faces the interior of the vehicle (not shown) to which the decorative panel (1) is secured.

[0047] The inner surface (31) of the glass sheet (30) is further at least partially coated with a layer (300) having a luminous transmittance of either less than 1% or at least 1%, which may be at least 3%, 5%, 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90%, 95%, 99%.

[0048] The glass sheet (30) is adhered to the carrier (10) via an adhesive layer (20), which completely covers the inner surface (31) of the glass sheet (30).

[0049] FIG. 1b shows a similar embodiment to FIG. 1a, except that an additional primer (350) is deposited on the inner surface (31) of the glass sheet (30) to improve the adhesion of the adhesive layer (20).

[0050] Referring to Figure 2a, a decorative panel (1) includes a carrier (10). The carrier is used to secure the decorative panel to the interior of a vehicle (not shown). Here, the carrier is shown having two protrusions (100) for securing the decorative panel (1). Other means for securing such decorative panels are well known to those skilled in the art.

[0051] The decorative panel (1) further includes a glass sheet (30). An inner surface (31) of the glass sheet (30) faces the carrier (10) and an outer surface (32) of the glass sheet (30) faces the interior of the vehicle (not shown) to which the decorative panel (1) is secured.

[0052] The inner surface (31) of the glass sheet (30) is further at least partially coated with an opaque layer (300) having a luminous transmittance of less than 1%.

[0053] The glass sheet (30) is glued to the carrier (10) via an adhesive layer (20). The adhesive layer (20) completely covers the inner surface (31) of the glass sheet (30). In this example, the adhesive layer (20) additionally covers the edges of the glass sheet (30). Such a configuration is interesting when the decorative panel (1) is combined with at least one light source (2). It therefore allows the passage of light from the light source (2) through the adhesive layer (20). The opaque layer (300) makes it possible to avoid light contamination from the light source (2) to the glass sheet (30).

[0054] FIG. 2b shows a similar embodiment to FIG. 2a, except that an additional primer (350) is deposited on the inner surface (31) of the glass sheet (30) to improve the adhesion of the adhesive layer (20).

[0055] Referring to Figure 3, the decorative panel (1) includes a carrier (10). The carrier is used to secure the decorative panel to the interior of the vehicle (not shown). The carrier may also be used to maintain the cold bent glass in its final deformed shape. Here, the carrier is shown with two protrusions (100) for securing the decorative panel (1). Other means of securing such decorative panels will be known to those skilled in the art.

[0056] The decorative panel (1) further includes a glass sheet (30). An inner surface (31) of the glass sheet (30) faces the carrier (10) and an outer surface (32) of the glass sheet (30) faces the interior of the vehicle (not shown) to which the decorative panel (1) is secured.

[0057] The inner surface (31) of the glass sheet (30) is further at least partially coated with an opaque layer (300) having a luminous transmittance of less than 1%.

[0058] The glass sheet (30) is adhered to the carrier (10) via an adhesive layer (20), which completely covers the inner surface (31) of the glass sheet (30).

[0059] In this example, the carrier (10) further comprises a hole (110). Such a configuration is interesting when the decorative panel (1) is combined with at least one light source (2). It therefore allows light from the light source (2) to pass through the carrier (10). In this case, the inner surface (31) of the glass sheet (30) that coincides with the hole (110) of the carrier (10) is not coated with an opaque layer (300) or is coated with a transparent or semi-transparent layer (310). The luminous transmittance of the transparent or semi-transparent layer can be at least 1%, 3%, 5%, 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90%, 95%, 99%.

[0060] An opaque layer (300) disposed at the locations where the inner surface (31) of the glass sheet (30) does not coincide with the holes (110) of the carrier (10) makes it possible to avoid contamination of light from the light source (2) to the glass sheet (30).

[0061] Referring to Figure 4, the trim panel (1) includes a carrier (10). The carrier is used to secure the trim panel to the interior of a vehicle (not shown). Here, the carrier is shown having two protrusions (100) for securing the trim panel (1). Other means for securing such trim panels are well known to those skilled in the art.

[0062] The decorative panel (1) further includes a glass sheet (30). An inner surface (31) of the glass sheet (30) faces the carrier (10) and an outer surface (32) of the glass sheet (30) faces the interior of the vehicle (not shown) to which the decorative panel (1) is secured.

[0063] The inner surface (31) of the glass sheet (30) is further at least partially coated with an opaque layer (300) having a luminous transmittance of less than 1%.

[0064] The glass sheet (30) is adhered to the carrier (10) via an adhesive layer (20), which completely covers the inner surface (31) of the glass sheet (30).

[0065] In this example, the carrier (10) further comprises a recess (120). Such a configuration is interesting when the decorative panel (1) is combined with at least one light source (2) integrated in the carrier (10). In this case, the inner surface (31) of the glass sheet (30) that coincides with the recess (120) of the carrier (10) is not coated with an opaque layer (300) or is coated with a transparent or semi-transparent layer (310). The luminous transmittance of the transparent or semi-transparent layer may be at least 1%, 3%, 5%, 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90%, 95%, 99%.

[0066] The opaque layer (300), located where the inner surface (31) of the glass sheet (30) does not coincide with the recess (120) of the carrier (10), makes it possible to avoid contamination of light from the light source (2) to the glass sheet (30).
