Abstract

A head-up display for a motor vehicle includes a housing, which may be integrated into an instrument panel of the motor vehicle. A combiner is configured to combine an image of the head-up display and an environment in front of the motor vehicle observable through the combiner. The combiner is movable from a position of non-use into a position of use. An image generator is configured to generate the image. A cover may be brought into a closed position, which covers the housing when not in use. The cover has an opening to enable an emission of light of a light beam of the image generator with the cover closed.

Claims

1. A head-up display of a motor vehicle comprising:

a housing configured to be integrated into an instrument panel of the motor vehicle;

an image generator configured to generate an image;

a combiner configured to combine the image and an environment in front of the motor vehicle and observable through the combiner, wherein the combiner is movable from a position of non-use into a position of use; and

a cover positionable into a closed position, which covers the housing when not in use, wherein the cover has an opening configured to emit light of a light beam of the image generator with the cover in the closed.

2. The head-up display according to claim 1, wherein the image generator comprises at least one LED for generating the light beam.

3. The head-up display according to claim 1, further comprising a deflection mirror configured to deflect the image onto the combiner.

4. The head-up display according to claim 3, wherein the deflection mirror is adjustable, wherein at least one light beam, which is generated by the image generator, with the combiner situated in the position of non-use, is directed to a windscreen of the motor vehicle such that the reflection of the light beam lies in a field of vision of a driver of the motor vehicle.

5. The head-up display according to claim 1, further comprising a light-permeable element provided in the opening.

6. The head-up display according to claim 5, wherein the light-permeable element comprises at least one of a pane or a filter.

7. The head-up display according to claim 5, wherein the light-permeable comprises a color filter.

8. The head-up display according to claim 1, wherein the combiner includes the cover.

9. The head-up display according to claim 8, wherein the combiner comprises a color filter.

10. The head-up display according to claim 1, further comprising a drive mechanism configured to move the combiner between the position of non-use and the position of use.

11. The head-up display according to claim 10, wherein the drive mechanism comprises at least one of a linear drive or a rotary drive.

12. A motor vehicle comprising:

an instrument panel;

a housing integrated into the instrument panel;

an image generator configured to generate an image;

a combiner configured to combine the image and an environment in front of the motor vehicle and observable through the combiner, wherein the combiner is movable from a position of non-use into a position of use; and

a cover positionable into a closed position, which covers the housing when not in use, wherein the cover has an opening configured to emit light of a light beam of the image generator with the cover in the closed.
