Thus, the trims elements made of glass sheet may host different functionalities around electronic gadgetry and vehicle control information, connectivity, touch, display and audio. Thus the upper part of the center console may be made of glass sheet in a larger part of the upper part of the center console, without anesthetically buttons to control for example audio control volume and on/off, engine start/stop system, head up display control system, glazing opening, display system control, allows circulation of information display in the car on the different glass panels, control of SMART glazings, etc. According to this embodiment, the touch panel may be curved for improved ergonomics conditions of drivers/passengers (view adaptation and glare related issues). Cavities on trim elements can be processed to provide haptic feedback on a plain glass sheet for easy detection of touch sensors (for safety reason of the driver).

(36) In a preferred embodiment of the invention, the trim elements are made in one piece of glass sheet extended from the rear of the console body to the dashboard wherein touch functions are integrated.

Such openings may be covered by openable piece of glass sheet.

(41) According to one embodiment of the invention, the trim elements may be glued or fixed to the console body by encapsulation.

(42) Advantageously, the center console has an upward opening and capable of storing therein baggage providing a storage compartment. For opening the storage compartment of the console body, the vehicle center console has a first opening mode for opening the compartment of the console base by for example, sliding the trim elements. Then, the storage compartment lid is made of glass sheet and can be encapsulated for instance with PU, TPE, PVC, LCP, TPO or similar materials in order to be flush with the rest of the center panel when closed. This encapsulation is not limited to this area of the center console.

(43) According to the invention, the center console is made of flat glass sheet which can be bended or thermoformed to adapt with the shape of the car. The flat glass sheet may be processed to be decorative or in order to give an access to CD, plugs, storage compartment, cup holders systems, buttons, gearstick, cigarette lighter or auxiliary power point, audio controls, the climate control/air condition system and possibly a display screen (or other type of system requiring a hole drilled in the glass sheet surface).

(76) According to another embodiment, the glass sheet is coated with at least one anti-fingerprint layer or has been treated so as to reduce or prevent fingerprints. This embodiment is also advantageous in the case of use of the glass sheet of the invention as front face of a touchscreen. Such a layer or such a treatment may be combined with a transparent and electrically conducting thin layer deposited on the opposite face. Such a layer may be combined with an antireflection layer deposited on the same face, the anti-fingerprint layer being on the outside of the stack and thus covering the antireflection layer.

(77) According to the applications and/or properties desired, other layers can be deposited on one and/or the other face of the glass sheet according to the invention.

(78) The glass sheet according to the invention may be a glass sheet obtained by a floating process, a drawing process, a rolling process or any other process known to manufacture a glass sheet starting from a molten glass composition. According to a preferential embodiment according to the 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 consists in pouring the molten glass onto a bath of molten tin, under reducing conditions.

(81) In order to provide a better esthetic of the center console, the trim elements may be made of a digital or silk screen printed glass sheet, an etched glass sheet, a painted/enameled glass sheet, a casted glass sheet, an anti-bacterial glass sheet, a colored float glass sheet.

(82) According to another embodiment of the invention, the trim elements are made of laminated glass sheet. According to this embodiment, at least one thermoplastic interlayer is used to laminate at least two glass sheets. Advantageously, a colored or active interlayer may be present between the at least two glass sheets. The interlayer or a layer between the glass and the interlayer might have a low refractive index (<1.43, <1.4, <1.38, . . . <1.3) to ensure TIR in the upper glass, if compatible from IR absorption point of view.

(83) According to another embodiment of the invention, the at least one trim element is made of heat treated glass sheet, for example annealed or tempered and/or bended glass sheet. Typically, this involves heating the glass sheet (coated or not) in a furnace to a temperature of at least 580° C., more preferably of at least about 600° C. and still more preferably of at least 620° C. before rapidly cooling down the glass substrate. This tempering and/or bending can take place for a period of at least 4 minutes, at least 5 minutes, or more in different situations.

(84) According to one embodiment of the present invention, the glass trim element may be a cover glass combined with a polycarbonate plate glued for example behind the cover glass and potentially a display glued behind.

(85) Thus, a glass trim element or a center console comprising at least trim element made of glass sheet according to the invention may provide a glass trim element or a center console having one or more of the following advantages: a higher mechanical/scratch resistance an improved stiffness/weight ratio a higher resistance to ageing/weathering (sun irradiation) possibility to provide a better finishing/aspect possibility to have a transparent trim element (for back lighting, screen integration, . . . ) possibility to have a glare control treatment and/or anti-finger prints coating a better recyclability a seamless connectivity with nomadic devices the glass trim element can harbor seamless audio functions (audioglass) a better hygienic aspect a better comfort/convenience some functionalities may be tailor-made for the occupant possibility of reconciliation of many different softwares into one single place for one Operating System.

(86) The present invention applies to trim or decorative elements present in the interior of a vehicle as doors handles contours, door panels, trim elements of the dashboard, back of seats . . . .

(87) Thus, the invention also relates to an assembly for motor vehicle's interior and more particularly for a car's interior comprising a glass trim element and a plastic frame as described above. The advantages of such as assembly are the same cited above.
