Abstract

The present invention relates to a display device, notably for a motor vehicle, comprising a projection module for generating an image for the purpose of a projection in the normal direction of looking of a user of the display device on an optical path, the display device comprising a reflection element, the reflection element being capable of being moved between a multitude of different display positions, the different display positions corresponding to different viewing positions of a user of the display device.

Claims

1. A head up display device for a motor vehicle, comprising a projection module for generating an image for projection in the normal direction of looking of a user of the head up display device on an optical path, wherein the head up display device comprises a reflection element, the normal direction of looking substantially corresponds to a viewing direction of the user through the reflection element toward a space in front of the motor vehicle, the reflection element being capable of being moved between a multitude of different display positions, the different display positions corresponding to different viewing positions of a user of the head up display device, wherein the reflection element is capable of being positioned, in addition to the multitude of different display positions, in a rest position, the reflection element in its different display positions being provided in the normal direction of looking of the user, and wherein, when the reflection element is moved between its rest position and one of its different display positions, the reflection element is subjected to a translational movement.

2. The head up display device as claimed claim 1, wherein the head up display device comprises a means for covering the reflection element, the cover means covering the reflection element when the reflection element is positioned in its rest position.

3. The head up display device as claimed in claim 1, wherein, between the different display positions of the reflection element, the reflection element is subjected to a rotary movement about a fixed axis of rotation.

4. The head up display device as claimed in claim 3, wherein the reflection element is rotated about the axis of rotation by a rotary motor element and by a transmission element.

5. The head up display device as claimed in claim 3, wherein the reflection element is rotated about the axis of rotation by a linear motor element and by a transmission element.

6. The head up display device as claimed in claim 3, wherein the axis of rotation of the reflection element is a physical axis.
