    [0001] DISCLOSURE DEVICE, IN PARTICULAR FOR MOTOR VEHICLE Description The present invention relates to a display device, in particular for a motor vehicle. Head-up display devices (HUD) are known, particularly with the projection of an image to a windshield as described in US 5214413 or to a reflection element. The high-vision vision display devices project information into the field of view of the space in front of the motor vehicle so that the driver of the motor vehicle can read this information without taking his eyes off the space in front of the vehicle. automobile. At the same time, the information can be read without modification of the accommodation of the eyes of the driver of the vehicle. It is advantageous that - depending on the needs of a user of the vehicle the reflection and / or display element may be used at several positions of the head (or eyes) of the vehicle user. A disadvantage of such devices according to the prior art consists in the fact that the efforts to achieve the connection between the support of a reflection element and / or display and the reflection element and / or display are relatively high. DE 10 144 491 C2 proposes to use a spring, but this causes comparatively high costs of the display device. The present invention is intended in particular to overcome the drawbacks of the prior art, and especially those mentioned above, and also aims to provide a high-head vision display device 30 having a reflection element and / or or display that is connected to its support reliably and with reduced costs. According to the present invention, this object is achieved by a display device, especially for a motor vehicle, comprising a projection module for generating an image for projection in the normal direction of view of a user of the device. display according to an optical path, the display device comprising a reflection and / or display element, the reflection and / or display element being able to be moved between a rest position and at least one display position, the display device comprising a support for the reflection element and / or display such that the reflection element and / or display is moved between its rest position and its at least one display position through the support, the rest position of the reflection element and / or display corresponding to a rest position of the support of the reflection element and / or display, and the display position of the reflection element and / or display corresponding to a display position of the support of the reflection element and / or display, the reflection element and / or display at least partially traversing a movement rotation between its rest and display positions, and the support of the reflection and / or display element at least partially traversing a translation movement between its rest and display positions, characterized in that reflection and / or display element and the support are connected via a first, second, third and fourth surface, the first and second surfaces being curved surfaces having a first radius, and the third and fourth surfaces; surfaces being flat or curved surfaces having a second radius, the second radius corresponding to at least twice the first radius.
    [0002] By such an embodiment of a display device, it is advantageously possible to make a connection between the reflection element and / or display and its support in a simple and inexpensive way. Another preferred refinement of the invention resides in the fact that the first and second surfaces are surfaces of the reflection and / or display element (13), and that the third and fourth surfaces are surfaces of the support (16) of the reflection and / or display element (13), the first and third surfaces and the second and fourth surfaces being supported against each other by means of a spring (18). ).
    [0003] Another preferred refinement of the invention resides in the fact that the spring (18) is configured in that the first and third surfaces, and the second and fourth surfaces allow relative rotational movement between the reflection element and / or display (13) and the support (16).
    [0004] According to a variant of the present invention, it is also preferred that the direction of the bearing force of the spring (18) is substantially parallel to the straight line connecting, on the one hand, the point of contact between the first and second third surfaces, and secondly the point of contact between the second and fourth surfaces. A preferred refinement of the invention lies in the fact that the reflection and / or display element is capable of being positioned in a multitude of different display positions. A preferred development of the invention lies in the fact that between the different display positions of the reflection element and / or display, the reflection element and / or display is subjected to a rotary movement and / or translational. Yet another preferred development of the invention lies in the fact that the reflection element and / or display is driven between its rest position and its at least one display position via a motor element.
    [0005] Other features and advantages of the invention will become apparent from reading the following description of a particular non-limiting embodiment of the present invention.
    [0006] BRIEF DESCRIPTION OF THE DRAWINGS The invention will be better understood thanks to the following description, which refers to preferred embodiments given by way of non-limiting example and explained with reference to the appended diagrammatic drawings, in which: FIG. 1 is a diagrammatic sectional view of a display device according to the present invention; FIG. 2 is a schematic sectional view of a portion of the display device according to the present invention with the reflection element and / or 3 is a schematic perspective view of a portion of the display device according to the present invention with the reflection and / or display element. DESCRIPTION OF THE DRAWINGS As shown in FIG. 1 of the accompanying drawing, a display device 10 according to the present invention comprises a projection module 11 which generates an image in the normal viewing direction of a user of the display device 1 0 in an optical path 12. The optical path 12 normally comprises at least one reflection element and / or display 13. In this way, the optical path 12 may comprise a (single) reflection element, as shown in FIG. In addition, the optical path 12 may also include two reflection elements. The display device 10 can be made with either a reflection element 13 or with a display element (for example a thin film transistor (in English TFT: Thin Film Transistor), or with a reflection element and The normal viewing direction 15 is the direction of view of a user of the display device 10, in particular a vehicle driver, when the latter is looking, in particular through a windshield 14, the outside which is in front of the vehicle.
    [0007] According to the present invention, the reflection and / or display member 13 is a member positioned at a distance from the windshield 14. According to a preferred embodiment of the present invention, the reflection element and / or the The display 13 may be positioned in a rest position and in at least one display position. When the reflection element and / or display 13 is positioned in its rest position, the reflection element and / or display 13 is for example positioned inside a housing of the display device 10. When the reflection and / or display element 13 is positioned in its display position, the reflection and / or display element 13 is typically positioned upright or almost vertically so that the user of the display device can look through the reflection and / or display element 13. The change of position of the rest position and the display position of the reflection and / or display element 13 is through a rotary movement and / or translation.
    [0008] Different positions of the reflection element and / or display 13 may correspond to different display positions and adapted to different heights of the user's head. The reflection and / or display element 13 is typically driven by a motor element, either directly or through a transmission element. The driving element may in particular be a linear motor element or a rotary motor element, in particular an electric motor element with a pitch.
    [0009] According to the present invention, a support element 16 or a support 16 is associated with the reflection and / or display element 13. The support 16 or the support element 16 is capable of being driven between different states of positioning, in particular via the motor element.
    [0010] In Figure 2, a schematic sectional view of a portion of the display device according to the present invention is shown. The reflection element and / or display 13 can be rotated according to the arrow 13 '. A translational movement of the support 16 of the reflection and / or display element 13 corresponds to the rotational movement along the arrow 16 '. To enable this movement, a first surface and a second surface are provided on the reflection and / or display element 13; and a third and a fourth surface are provided on the support 13. The first and second surfaces are surfaces of the reflection and / or display element 13, and the third and fourth surfaces are surfaces of the support 16 of the reflection and / or display element 13. The first and third surfaces are provided at the location indicated by the reference sign 18. The second and fourth surfaces are provided at the location indicated by the reference sign 17. At the location of the reference sign 18, a spring is provided to prevent a gap between the first and third surfaces, and between the second and fourth surfaces. The reflection and / or display element 13 and the support 16 are connected through the surfaces, the first and second surfaces being curved surfaces having a first (smaller) radius, and the third and fourth surfaces being flat or curved surfaces having a second (larger) radius. According to the present invention, the second radius corresponds to at least twice the first radius, but in reality much higher values of the proportion of rays is possible. When the third and fourth surfaces are flat surfaces, their radius corresponds to a very high value.
