Abstract

A passenger seat includes a first seat element and at least one second seat chamber element that are movable relative to each other, and which can be stood on a base of a transport means and has at least one optical transmission unit having a light input element, at least one light output element and at least one light guide path that runs from the light input element to the light output element and along which light is conducted. The optical transmission unit is provided for contact-free transmission of light in at least one operating state at at least one location of the light guide path that differs from a location of a light input into the light input element and from a location of light output from the light output element.

Claims

1. A passenger seat which comprises:

a first seat element and at least a second seat element which are movable relative to one another, and which passenger seat can be stood on a floor of a means of transportation,

at least one optical transmission unit having a light input element,

at least one light output element, and

at least one light guide path which runs from the light input element to the light output element and along which light is guided,

wherein the optical transmission unit is provided for transmitting light in a contactless fashion in at least one operating state, at at least one location of the light guide path which differs from a location of a light input into the light input element and from a location of a light output from the light output element, and

wherein the optical transmission unit has a light emission unit which is arranged at the first seat element, and a light-collecting unit which is arranged at the second seat element which is movable relative to the first seat element.

2. The passenger seat as claimed in claim 1, wherein

the contactless transmission of the light from the first seat element to the second seat element which is different therefrom and is movable relative to the first seat element takes place in discrete regions, delineated from one another, of a relative position of the first seat element and of the second seat element.

3. The passenger seat as claimed in claim 1, wherein the light guide path is formed at least partially by at least one optical waveguide.

4. The passenger seat as claimed in claim 1, wherein the optical transmission unit has at least one collimator unit.

5. The passenger seat as claimed in claim 1, wherein the light output element is formed by a beam-widening element.

6. The passenger seat as claimed in claim 1, wherein the first seat element is formed by a seat housing element which is fixedly arranged relative to the floor of the means of transportation.

7. The passenger seat as claimed in claim 6, wherein in at least one operating state the contactless transmission of the light takes place between the seat housing element which is fixedly arranged relative to the floor of the means of transportation and a seat element which is movable relative thereto.

8. The passenger seat as claimed in claim 1, wherein the first seat element is formed by a seat bottom and the second seat element is formed by an armrest.

9. The passenger seat as claimed in claim 8, wherein the contactless transmission of light occurs at least in a region of an end position of the armrest.

10. The passenger seat as claimed in claim 1, wherein

the contactless transmission of the light from the first seat element to the second seat element which is different therefrom and is movable relative to the first seat element takes place in discrete regions, delineated from one another, of a relative position of the first seat element and of the second seat element.

11. The passenger seat as claimed in claim 1, wherein the light guide path is formed at least partially by at least one optical waveguide.

12. The passenger seat as claimed in claim 1, wherein the optical transmission unit has at least one collimator unit.

13. The passenger seat as claimed in claim 1, wherein the light output element is formed by a beam-widening element.

14. The passenger seat as claimed in claim 2, wherein the light guide path is formed at least partially by at least one optical waveguide.

15. The passenger seat as claimed in claim 2, wherein the optical transmission unit has at least one collimator unit.

16. The passenger seat as claimed in claim 2, wherein the light output element is formed by a beam-widening element.

17. The passenger seat as claimed in claim 3, wherein the optical transmission unit has at least one collimator unit.

18. The passenger seat as claimed in claim 3, wherein the light output element is formed by a beam-widening element.

19. The passenger seat as claimed in claim 4, wherein the light output element is formed by a beam-widening element.
