Abstract

A projection system for optical reproduction of information or entertainment data for employment in the area of passenger transport (airplane, automobile area). Therein a laser projector is used for generating an image line by line upon surfaces within the vehicle internal space. By rotation or pivoting of the laser projector or displacement along a guide rail practically all surfaces in the internal space of the vehicle can be reached.

Claims

1. Projection device for reproduction of optical information and entertainment data in passenger transport means, thereby characterized, that for image production a laser projector is available, which includes an integrated deflection device, via which one or more laser beams are directed as a grid upon projection surfaces within the internal area of the passenger transport means, wherein the projection surfaces in the passenger transport means are formed by conventionally present internal structures, in particular by headrests, seatbacks, door molding or upholstery or dashboard.

2. Projection device according to claim 1, thereby characterized, that the laser projector includes a rotation or pivot device, by means of which the direction of projection can be changed.

3. Projection device according to claim 1 or 2, thereby characterized, that the projection device includes a displacement mechanism (for example one or more rails), by means of which the position of the laser projector can be varied in the internal space of the passenger transport means.

4. Projection device according to one of claims 1 through 3, thereby characterized, that means are available, via which, in the case of diagonal projection or nonplanar projection surfaces, the deflection device of the laser projector is controllable in such a manner that the compensation of the distortion brought about by the diagonal projection or as the case may be nonplanar projection surfaces, occurs.

5. Projection device according to one of claims 1 through 4, thereby characterized, that means are available, via which, in the case of diagonal projection or nonplanar projection surfaces, the deflection device of the laser projector is controllable in such a manner that the compensation of the distortion brought about by the diagonal projection or as the case may be nonplanar projection surfaces, occurs.
