Abstract

A display device, particularly for a vehicle, includes a base element and a combiner. The combiner moves by a drive mechanism between a position for use, in which a virtual image can be projected onto the combiner, and a stowed position. The drive mechanism includes a translation mechanism.

First claim

The invention claimed is:

1. A display device comprising: a base element; and a combiner which can be moved relative to the base element, wherein the combiner moves by a drive mechanism between a position for use, in which a virtual image can be projected onto the combiner, and a stowed position, wherein the drive mechanism comprises a translation mechanism, wherein the translation mechanism is a scissor mechanism; wherein the scissor mechanism includes a scissor articulation including an arrangement of at least two rods, the at least two rods each including an end location, the at least two rods forming a scissor member, the at least two rods rotatably connected to each other in a central region of each rod at an intersection location of the scissor member;
wherein the drive mechanism includes a drive engaged to the intersection location in order to move the combiner between the position for use and the stowed position by moving the intersection locating in a longitudinal direction; and
wherein the scissor articulation is compressible in the longitudinal direction into a retracted position when the end locations of the at least two rods are separated from each other in a transverse direction perpendicular relative to the longitudinal direction.

2. The display device as claimed in claim 1 , wherein the combiner carries out a linear movement and a rotation movement when moving from the position for use into the stowed position.

3. The display device as claimed in claim 2 , wherein the same drive is provided for the linear movement and the rotation movement.

4. The display device as claimed in claim 2 , wherein the movement of the combiner is carried out along a curved guide.

5. The display device as claimed in claim 4 , wherein the combiner is supported in the guiding rail by a rotatable guiding element.

6. The display device as claimed in claim 5 , wherein the guiding element has two guide means which are supported separately from each other in the guiding rail and which are moved along different paths when the combiner is moved.

7. The display device as claimed in claim 5 , wherein a rotary bearing is provided on the guiding element.

8. The display device as claimed in claim 1 , wherein the drive mechanism comprises a linear motor or a rotary drive.

9. The display device as claimed in claim 1 , wherein the drive mechanism is at least partially produced from a material which comprises a shape memory alloy, wherein the drive mechanism preferably has a control unit, which is configured to apply a control current to the shape memory alloy.
