Abstract
Claims
1. A protective element (30) of a transmission unit (22) for vehicle control information, The transmission unit (22) comprises at least one screen (28) capable of emitting light rays, and the protective element (30) is adapted to be positioned above and at a distance from the transmission unit (22) on the emission path of the light rays coming from the one or more screens (28) of the transmission unit (22) to protect one or more screens (28), and the protective element (30) is at least partially transparent, and the protective element (30) is, Optical magnification characteristics over at least a portion of the protective element (30) through which at least a portion of the light rays from one or more screens (28) are intended to pass, and / or A protective element (30) having a ray redirection property over at least a portion of the protective element (30) that is intended to redirect the rays from the one or more screens (28) so as to redirect the rays from the one or more screens (28).
2. The protective element (30) according to claim 1, wherein the protective element (30) is at least partially transparent plate having an incident diopter (32) and an outgoing diopter (34), each diopter (32, 34) having anti-reflective properties, and the protective element (30) is preferably made of glass or plastic.
3. The protective element (30) according to claim 1 or 2, wherein the light ray direction conversion characteristics of the protective element (30) are achieved by overmolding a film including a prism onto the protective element (30) and / or by laser microstructuring the protective element (30).
4. The protective element (30) according to any one of claims 1 to 3, wherein the protective element (30) has polarization correction properties over at least a portion of the protective element (30) through which at least a portion of the light rays from the one or more screens (28) are intended to pass, so as to correct the polarization of the light rays from the one or more screens (28).
5. The protective element (30) according to any one of claims 1 to 4, wherein the protective element (30) has colorimetric correction characteristics over at least a portion of the protective element (30) through which at least a portion of the light rays from the one or more screens (28) are intended to pass, so as to correct the colorimetric measurement of the light rays from the one or more screens (28).
6. The protective element (30) according to any one of claims 1 to 5, wherein the protective element (30) has opacity, and the opacity is fixed or can be varied by electrochromism or photochromism.
7. The protective element (30) according to any one of claims 1 to 6, wherein the protective element (30) has a viewing angle correction characteristic over at least a portion of the protective element (30) through which at least a portion of the light rays from the one or more screens (28) are intended to pass, so as to correct the viewing angle of the image (IM) resulting from the light rays for the driver (16) or passenger of the vehicle.
8. The protective element (30) according to any one of claims 1 to 7, wherein the protective element (30) comprises a heating element.
9. The protective element (30) according to any one of claims 1 to 8, wherein the protective element (30) has corrective properties for optical distortion or birefringence over at least a portion of the protective element (30) through which at least a portion of the light rays from the one or more screens (28) are intended to pass, in order to correct the rendering of an image (IM) resulting from the light rays.
10. A head-up display device (12) for a vehicle, A support (20) suitable for positioning facing the upper body of a driver (16) in a driving position, wherein the support (20) comprises at least one at least partial reflective portion called a useful portion (24), A transmission unit (22) for control information of the vehicle, the transmission unit (22) comprising at least one screen (28) capable of emitting light rays toward the useful portion (24) of the support (20) such that the reflection of light rays from the support (20) forms at least one useful image (IM) within the field of view of the driver (16) in a driving position, The protective element (30) of the transmission unit (22) is at least partially transparent, and the protective element (30) is positioned above the transmission unit (22) and at a distance from the transmission unit (22) between the support (20) and the transmission unit (22) on the emission path of the light rays coming from the one or more screens (28) to protect one or more screens (28), wherein the protective element (30) is Optical magnification characteristics over at least a portion of the protective element (30) through which at least a portion of the light rays from one or more screens (28) are intended to pass, and / or A head-up display device (12) having ray redirection properties over at least a portion of the protective element (30) through which at least a portion of the light rays from the one or more screens (28) are intended to pass, so as to redirect the light rays from the one or more screens (28).
11. A vehicle comprising an instrument panel (31) and a head-up display device (12) according to claim 10, wherein the protective element (30) is incorporated into the instrument panel (31) of the vehicle.
