Abstract

The present disclosure pertains to a seat device of an aircraft or spacecraft, having a seat which comprises a headrest, and a loudspeaker device which includes at least one pair of loudspeakers which are spaced apart from one another and located in the region of the headrest.

First claim

What is claimed is:

1. A seat system of an aircraft or spacecraft, the seat system comprising:
a first seat which comprises a headrest, a front side of the headrest being adapted to support a head of a first passenger and a rear side of the headrest being oriented toward a second seat located behind the first seat; and
a loudspeaker device which comprises at least one pair of loudspeakers which are spaced apart from one another and arranged at the rear side of the headrest of the first seat, wherein the loudspeaker device is adapted to emit signals that are audible in a listening region in which a head of a second passenger seated in the second seat is positioned.

2. The seat system according to claim 1 , wherein the pair of loudspeakers is located at the sides of the passenger's head and inclined towards the passenger's head in such a way that the pair of loudspeakers transmits signals towards a region in which the passenger's head is intended to be positioned.

3. The seat system according to claim 1 , wherein the seat system comprises a control device which is designed to control the pair of loudspeakers such that the signals emitted by the loudspeakers are audible in a listening region in which the passenger's head is intended to be positioned.

4. The seat system according to claim 1 , wherein the control device is designed to control the pair of loudspeakers so as to create a suppression region adjacent to the listening region, the signals emitted by the pair of loudspeakers not being audible in this suppression region.

5. The seat system according to claim 1 , wherein the loudspeaker device is connected to the headrest of the first seat by a cover.

6. The seat system according to claim 1 , wherein the loudspeaker device is designed as an integral part of the first seat.

7. The seat system according to claim 1 , wherein a second pair of loudspeakers is located on the second seat at the sides of the passenger's head and inclined towards the passenger's head in such a way that the second pair of loudspeakers transmits signals towards the region in which the passenger's head is intended to be positioned.

8. The seat system according to claim 7 , wherein the second pair of loudspeakers is connected in the region of the headrest of the second seat by a cover.

9. The seat system according to claim 1 , wherein audio signals are provided to the pair of loudspeakers by an electronic device which is supplied by the passenger.

10. The seat system according to claim 1 , wherein a detection unit for detecting whether a seat position is occupied is provided and interrupts a production of the listening region as soon as the detection unit detects that the first seat is not occupied.

11. A cover of an aircraft or spacecraft, the cover comprising:
a loudspeaker device according to claim 1 , which is connected to the cover.

12. The cover according to claim 11 , wherein the pair of loudspeakers is located at the sides of the passenger's head and inclined towards the passenger's head in such a way that the pair of loudspeakers transmits signals towards a region in which the passenger's head is intended to be positioned.

13. The cover according to claim 11 , wherein the cover comprises a control device which is designed to control the pair of loudspeakers such that the signals emitted by the loudspeakers are audible in a listening region in which the passenger's head is intended to be positioned.

14. The cover according to claim 13 , wherein the control device is designed to control the pair of loudspeakers so as to create a suppression region adjacent to the listening region, the signals emitted by the pair of loudspeakers not being audible in this suppression region.

15. An aircraft or spacecraft comprising:
a seat device comprising:
a seat which comprises a headrest; and
a cover comprising a loudspeaker device according to claim 1 .
