Abstract:
The invention relates to a compact head-up display ( 1 ), in particular for a motor vehicle, comprising: an image generator ( 9 ) for displaying an image ( 7 ) on a display surface ( 2 ); a semi-reflective optical element ( 3 ), typically a windscreen, arranged at a distance from the image generator ( 9 ) so as to form a virtual image ( 4 ) of the image ( 7 ) from the image generator ( 9 ) on a first side of the optical element ( 3 ), said virtual image ( 4 ) being visible from a view window ( 5 ) located on a second side of the optical element ( 3 ). The compact head-up display ( 1 ) comprises an optical part ( 10 ), typically a pentaprism, for extending the optical path of the image ( 7 ) passing therethrough from the image generator ( 9 ) to the optical element ( 3 ), said optical part ( 10 ) comprising an image input face ( 14 ) and an image output face ( 17 ), as well as first ( 15 ) and second ( 16 ) reflective surfaces. The first reflective surface ( 15 ) reflects the image from the input surface ( 14 ) towards the second reflective surface ( 16 ), and the second reflective surface ( 16 ) reflects the image ( 7 ) from the first reflective surface ( 15 ) towards the output surface ( 17 ), the input surface ( 14 ) also being substantially in contact with the display surface ( 2 ) of the image generator ( 9 ). The image generator ( 9 ) and the optical part ( 10 ) move together.

Claim (Index 1):
A compact head-up display for an automobile vehicle, comprising:\n an image generator configured for displaying an image on a display surface; a semi-reflecting optical element arranged at a distance from the image generator and configured for forming, on a first side of the optical element, a virtual image of the image of the image generator, the virtual image being visible from a viewing window situated on a second side of the optical element, wherein the display comprises an optical component configured for lengthening the optical path of the image passing through it going from the image generator to the optical element, the optical component comprising at least one entry face and one exit face for the image, together with a first reflecting face and a second reflecting face, the first reflecting face being configured for reflecting the image from the entry face toward the second reflecting face, and the second reflecting face being configured for reflecting the image from the first reflecting face toward the exit face, the entry face being further substantially in contact with the display surface of the image generator.
