Abstract
A light guide (1) is provided for an illuminable screen (2) of a motor vehicle seat (3). The light guide (7) has a pin-shaped light-introducing region (4) and a plate-shaped light-emitting region (5). The pin-shaped light-introducing region (4) transitions into the plate-shaped light-emitting region (5) over an arch region (6) expanding from the pin-shaped light-introducing region (4) to achieve a compact design.

A light guide (1) for an illuminable screen (2) of a motor vehicle seat (3), the light guide (1) comprising:
- a pin-shaped light-introducing region (4) extending in a z-direction;
- an arch region (6) extending from the pin-shaped light-introducing region (4), the arch region (6) expanding in a y-direction transverse to the z-direction and curving back toward the pin-shaped light-introducing region (4);
- a plate-shaped light-emitting region (5) extending from the arch region (6) and disposed forward of the pin-shaped light-introducing region (4) in an x-direction that is transverse to the z-direction and the y-direction so that the plate-shaped light-emitting region (5), the arch region (6) and the pin-shaped light-introducing region (4) define a substantially U-shape, with a surface of the plate-shaped light-emitting region (5) that faces forward in the x-direction and away from the a pin-shaped light-introducing region (4) defines the illuminable screen (2).

- a pin-shaped light-introducing region (4);
- an arch region (6) expanding from the pin-shaped light-introducing region (4);
- a plate-shaped light-emitting region (5) extending from the arch region (6) so that the pin-shaped light-introducing region (4) transitions into the plate-shaped light-emitting region (5) over the arch region (6), and a guide pin (7) arranged on the pin-shaped light-introducing region (4).
A motor vehicle seat (3) comprising:
- a backrest (25) with a forwardly facing surface;
- and a U-shaped curved light guide (1) having a light-introducing region (4) at a position rearward of the backrest;
- an arch region (6) extending from the light-introducing region (4) and curving forward over a top of the backrest (25);
- and a plate-shaped light-emitting region (5) extending from the arch region (6) and disposed adjacent a front surface of the backrest (25), the plate-shaped light-emitting region (5) having an illuminable screen (2) facing forward and away from the backrest (25).
