Description

ANTI-GLARE AND DISPLAY DEVICE FOR. MOTOR VEHICLE.

Field of the invention

The present invention relates to an anti-dazzle and display device for a motor vehicle.

Invention background

Motor vehicles are generally equipped at each front seat with an anti-dazzle device conventionally comprising a sun visor pallet pivotally mounted about a horizontal axis fixed on the roof of the vehicle, between a folded storage position in which this the sun visor pallet is leaning against a front surface of the roof roof and a service position in which the said sun visor pallet extends opposite the windshield so as to protect the eyes of the driver or the front passenger from the rays of the sun. Sun.

We know, in particular from patent application WO 98/57216, such anti-glare devices integrating a digital display screen of LCD type ("Light Crystal Display" in English) fixed on a central portion of the rear face of the sun visor pallet facing this user when this pallet occupies its service position.

To view the display screen, the user must therefore deploy the sun visor pallet in the service position, even if the outside light is not dazzling.

In such a configuration, the visibility of the user is then disturbed by the peripheral zone of the pallet surrounding this display screen.

Japanese patent application JP 2004-155316 discloses a sun visor for a vehicle comprising a sun visor pallet pivotally mounted about a horizontal axis fixed on the roof of the vehicle, between a folded storage position in which this visor pallet is backed against a front surface of the roof panel and a service position in which said pallet visor extends opposite the windshield.

This sun visor also comprises and a display screen mounted pivoting about this same horizontal axis between a retracted position in which this screen is housed in a window of complementary shape formed in the central part of the pallet, and an extended position in which the screen protrudes from the face of the pallet opposite the roof pavilion when the latter occupies its storage position so that its display surface is oriented towards the rear of the passenger compartment when the pallet occupies this storage position.

In the retracted position of the display screen, the sun visor pallet can thus be freely pivoted by the user between its storage position and its service position.

Furthermore, when this pallet occupies its storage position, the fact that the display screen is pivotally mounted relative to the pallet allows the user to deploy it in its extended position.

Such a sun visor therefore allows the user to view the display surface of the screen without his field of vision being disturbed by the palette.

In general, all of these sun shading devices only incorporate display screens which are reduced in size because they are limited by that of the pallet, the dimensions of which are within a standardized range capable of being suitable for most users.

In concrete terms, this means that the display area of these integrated screens cannot exceed 6 or 7 inches diagonally (15 to 18 cm), which forces the user to stay close to this screen to have correct visibility and 'thus prevents taking full advantage of it to be entertained when the back of his seat occupies a leaning position of comfort.

OBJECT AND SUMMARY OF THE INVENTION The present invention therefore aims to improve the situation.

To this end, it offers an anti-glare and display device for a motor vehicle comprising a screen provided with a display surface and a sun visor pallet mounted articulated in rotation about the same horizontal axis integral with the roof pavilion. said vehicle;

characterized in that said display screen has a recess formed on its face opposite to said display surface, this screen being able to pivot between a storage position in which it is leaning against said roof pavilion and a position of use in which its display surface is oriented towards the rear of the passenger compartment of said vehicle, said pallet being able to pivot between a retracted position in which it is housed in said recess and a deployed position in which it projects from said screen so as to protect the user's eyes from the sun's rays when the screen occupies said storage position.

The particular arrangement of the device according to the invention makes it possible to use a large display screen offering optimum visual comfort for the user, without impacting the size of the sun visor pallet which can keep standardized dimensions suitable to most users.

This device is particularly well suited to high-end vehicles with an autonomous driving system offering the possibility for the driver to relax during the automated driving phases.

Detailed description of an embodiment

As illustrated in FIGS. 1 to 4, the device according to the invention 10 comprises a rectangular liquid crystal display (LCD) screen 20 provided with a display surface 21 and mounted articulated in rotation around a horizontal axis A secured to the front portion of the roof roof 2 of a vehicle located near its windshield 3.

The screen 20 is able to pivot between a storage position in which it is leaning against a front portion of the roof pavilion 2 (see FIGS. 1 and 2) and a position of use in which its display surface 21 is oriented. towards the rear of the passenger compartment so as to allow the driver or front passenger to view it (see Figure 3).

This display screen 20 also has a parallelepiped recess 22 formed on its face opposite the display surface 21.

The device 10 also includes an opaque sun visor pallet 30 having dimensions complementary to those of the recess 22 and also being mounted articulated in rotation about the horizontal axis A.

This sun visor pallet 30 is able to pivot between a retracted position in which it is housed in the recess 22 (see FIGS. 1 and 3) and a deployed service position in which it projects from the screen 20 so as to protect the eyes of a user (driver or front passenger) of the sun's rays when this screen 20 occupies its storage position where it is leaning against the roof panel 2 (see FIG. 2).

In the retracted position of the sun visor pallet 30, the display screen 20 can thus be freely pivoted by the user from its storage position to its position of use (change from the configuration of FIG. 1 to that in Figure 3).

Furthermore, when this display screen 20 occupies its storage position, the sun visor pallet 30 can be freely pivoted by the user between its retracted position and its deployed position making it possible to protect his eyes from the rays of the sun (passage of the configuration of Figure 1 to that of Figure 2).

The screen 20 is provided with a capacitive touch matrix making it possible to identify the position of the user's finger by detecting the transfers of electrical charge taking place towards this finger from the area of the display surface with which it is in touch.

Preferably, this matrix is of the multipoint type, which means that it is capable of detecting several simultaneous presses of different fingers of the user on the display surface.

As a variant, and according to certain criteria of price, impact resistance, precision or size, the touch matrix will be of a different type: resistive, infrared, surface wave or even with strain gauges.

The screen 20 is connected to the on-board computer of the vehicle so as to have access to and be able to control the media applications integrated into this on-board computer such as for example and in a nonlimiting manner, the applications for reading audio files / video, television, web browsing, telephony, videoconferencing, messaging, calendar consultation, games, or even office applications, etc.

Advantageously, the screen 20 also includes a camera (not visible in the figures) located so as to be turned towards the driver or the front passenger when this screen 20 occupies its position of use.

A control button is provided on the touch screen interface 20 to display in real time the images captured by this camera so as to allow the user to see himself as in a mirror.

The portion of the image to be displayed, as well as other display parameters such as the zoom level, the brightness, the contrast or the colorimetry can also be adjusted by means of tactile adjustment sliders arranged on a peripheral portion of the display surface or performing certain predefined touch gestures (for example of the “pinch to zoom” type).

The display surface of the screen 20 advantageously has a diagonal of between 20 and 50 cm (or between 10 and 20 inches) allowing the user to benefit from a visual comfort markedly improved compared to that of the screens of the screen. art integrated into the sun visor palette.

The large dimensions of the screen 20 also allow it to occasionally serve as a sun visor for small people insufficiently protected from the sun's rays by the pallet 30.

As illustrated in FIG. 4, the screen 20 comprises two rings 23, 24 extending at the two ends of one of its longitudinal edges and being crossed by a metallic pivot arm 25 forming the horizontal axis of rotation A , this arm 25 comprising two vertical bent ends 27, 28 detachably snapped and freely rotatable about their axis Bi, B ₂ on two respective hollow cylindrical support members 4, 5 extending vertically from the roof of the vehicle to which they are rigidly fixed.

FIG. 5 represents an enlarged perspective view of one of the bent ends of the pivot arm 25 snapped onto a support member 4.

This latter mold molding from a thermoplastic material has a rectangular cutout 6 formed on its cylindrical wall in order to allow the snap-fitting of the bent end 27 of the arm 25. Its internal face also has a circular rib 7 extending in a horizontal plane and designed to receive a corresponding groove 29 formed on the bent end 27, so as to ensure the vertical retention of the latter while allowing its free rotation about its axis Bi.

Such an arrangement allows the user, by unclipping one of these bent ends 27, 28, to pivot the arm 25 and therefore this screen 20 around the corresponding vertical axis (Bi, B ₂ ) of the other bent end so as to drive it to the right or to the left in order for example to improve the vision of this screen by certain rear passengers of the vehicle.

In addition to being able to pivot around the horizontal axis A, the sun visor pallet 30 is able, when the display screen 20 occupies its storage position, to pivot around an axis C perpendicular to the axis A and to slide along this axis A so that, in its deployed service position, it can follow the relative movement of the sun vis-à-vis the vehicle in order to ensure optimum protection of the eyes of the user.

All these movements are made possible by a rod 31 housed freely rotating in a cylindrical bearing formed in this pallet 30 along and near one of its lateral edges, this rod 31 being provided at one of its ends. projecting from a longitudinal edge of this pallet 30 of a ring 32 crossed by the pivot arm 25 and being able to slide along the latter.

The pallet 30 further comprises a hook 33 extending from the end opposite to the ring 32 of its longitudinal edge from which protrudes this ring 32, and being detachably snapped onto the pivot arm 25.

Note that this hook must first be separated from the pivot arm 25 to allow the pallet 30 to pivot about the axis C and / or the latter to slide along the axis A).

According to variant embodiments, the screen incorporates a stand-alone module for playing audio / video files as well as at least one connection port (such as for example a USB socket or a memory card slot) allowing the connection of peripheral devices. external storage.

The screen can also integrate a stand-alone television module capable of receiving and broadcasting television signals.

According to other alternative embodiments, the kinematics of movement of the screen and / or of the pallet are different: the latter may for example have only one degree of freedom to pivot around the horizontal axis A.

According to still other alternative embodiments:

- the screen is based on a different technology such as OLED or plasma;

- The screen is devoid of touch matrix and includes a plurality of control buttons formed on the periphery of its display surface; and or

- The pallet includes a pocket provided on its face affixed against the screen when it occupies its retracted position and sized to be able to store road maps there.

Of course, the present invention is not limited to the embodiments described and shown, but it encompasses all of the alternative embodiments within the reach of the skilled person.
