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.
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.

1. Field of the Invention
The invention concerns projection systems for optical display of information or entertainment data. In particular, the invention concerns projection devices for employment in the area of passenger transport (airplanes, trains, automotive fields).
2. Description of the Related Art
This task is solved with a projection system for display of optical information and entertainment data in passenger vehicles, comprising a laser projector for projecting an image, the laser projector including an integrated deflector via which one or more laser beams are directed in a scanning manner upon a projection surface within the internal area of the passenger vehicle, wherein the projection surface in the passenger vehicle is a surface of a conventional interior structure, in particular headrests, seatbacks, door molding or upholstery, or the dashboard.
In the inventive projection device, a laser projector is employed for projection. In contrast to a conventional projector, here the display of the image occurs by the scanning of one or more laser beams, so that the image is constructed line-by-line of individual image points (pixels), as for example in the case of a PC or TV monitor. Therein by the selection of the number of lines and the pixel density the resolution of the reproduced image can be varied broadly.
Likewise, with such a laser projector the image size can be varied over a broad range, since it is only dependent upon the respectively selected maximal X and Y control values of the laser deflector device integrated in the projection head (for example reflecting oscillating mirror system).
