    [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 and / or display element such that the reflection and / or display element is moved between its rest position and its - at at least one display position via the support, the reflection and / or display element at least partly traversing a relative rotational movement relative to the support of the reflection element and / or display, between the rest and display positions of the reflection and / or display element, the relative rotational movement being provided around an axis of rotation, the reflection and / or display element and the support being linked via first, second, third, fourth, and fifth surfaces being planar surfaces, and via a sixth and seventh surfaces being curved surfaces, the first, second, third, and fourth surfaces being parallel to the axis of rotation. 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 sixth and seventh surfaces are surfaces of the reflection and / or display element, and that the first, second, third, fourth, and fifth surfaces are surfaces of the support of the reflection and / or display element, the first, second and sixth surfaces and the third, fourth, fifth and seventh surfaces being supported against each other by means of springs .
    [0002] Another preferred refinement of the invention resides in the fact that the springs are configured in that the first, second and sixth surfaces and the third, fourth, fifth and seventh surfaces allow a relative rotational movement between the reflection element and the / or display and support.
    [0003] According to a variant of the present invention, it is also preferred that the first and second surfaces, as well as the third, fourth, and fifth surfaces are inclined toward one another. Another preferred embodiment of the invention lies in the fact that 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 and / or display element corresponding to a display position of the support of the reflection and / or display element. Yet another preferred development of the invention lies in the fact that the support of the reflection element and / or display at least partially traverses a translational movement between its rest and display positions. 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 improvement according to the present invention resides in the fact that the reflection and / or display element is driven between its rest position and its at least one display position via a driving element. , in particular a stepping motor. 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. BRIEF DESCRIPTION OF THE DRAWINGS The invention will be better understood from 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 schematic sectional view of a display device according to the present invention; Fig. 2 is a schematic view of the reflection and / or display element of the display device according to the present invention; and Figures 3 to 8 are schematic perspective views of a portion of the display device according to the present invention with the reflection and / or display element and its support.
    [0004] DESCRIPTION OF THE DRAWINGS As shown in FIG. 1 of the accompanying drawing, a display device 10 according to the present invention includes a projection module 11 which generates an image in the normal viewing direction of a user of the display device 10. according to an optical path 12. The optical path 12 normally comprises at least one reflection and / or display element 13. In this way, the optical path 12 may comprise a (single) reflection element, as shown in FIG. Moreover, the optical path 2 may also comprise 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 driver of a motor vehicle, when he looks, in particular through a windshield 14, the outside. In accordance with the present invention, the reflection and / or display element 13 is an element positioned at a distance from the windshield 14. According to a preferred embodiment of the present invention, the the reflection and / or display element 13 can be positioned in a rest position and in at least one display position When the reflection and / or display element 13 is positioned in its rest position, the reflection and / or display element 13 is for example positioned inside a housing of the display device 10.
    [0005] 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, especially the driver of the motor vehicle, can look through the reflection element and / or display 13. The change of position of the rest position and the display position of the reflection element and / or display 13 is through a rotary movement and / or translation.
    [0006] 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. According to the present invention, a support member 16 or a support 16 is associated with the reflection and / or display element 13.
