Abstract

The invention essentially concerns an aircraft seat (1), comprising control units (17.2, 22.2, 27), at least one node (11-15) to execute a particular action or function, and a display (22.1) for viewing video data. Said node (11-15) and said display (22.1) are capable of being actuated by the control units (17.2, 22.2, 27). A keyboard (17.1) for transmitting a command signal addressed to the control units (17.2, 22.2, 27) is connected to said control units (17.2, 22.2, 27). The control units are shared between the display (22.1), the key board (17.1) and the node (11-15).

Claims

1-17. -17. (canceled)

18. An aircraft seat, comprising:

at least one node for performing a predetermined action or fulfilling a predetermined function;

a first control unit for actuating said at least one node;

a keyboard for transmitting an instruction signal to the first control unit;

a multiplexed communications bus for connecting the first control unit, said at least one node, and the keyboard; and

a first pack housing the first control unit and the keyboard, the first control unit being in communication with the keyboard and positioned behind the keyboard.

19. The seat of claim 18, further comprising:

a screen for displaying video information; and

a second control unit for controlling the screen and connected to the first control unit via a high-bit-rate network; and

a second pack housing the second control unit and the screen, the second control unit being in communication with the screen and positioned behind the screen.

20. The seat of claim 19, wherein the first control unit is operable to control the screen when the second control unit is inoperable.

21. The seat of claim 19, wherein the second control unit comprises video and audio data.

22. The seat of claim 21, wherein the first control unit comprises programs, video and audio data which can replace a limited number of programs, video and audio data of the second control unit when the second control unit is inoperable.

23. The seat of claim 19, wherein the second control unit is operable to control said at least one node when the first control unit is inoperable.

24. The seat of claim 23, wherein the second control unit comprises programs and data which can replace a limited number of programs and data of the first control unit when the first control unit is inoperable.

25. The seat of claim 24, wherein the second control unit comprises programs and data for controlling movement of the seat from a reclining position to a seated position.

26. The seat of claim 19, wherein the first and second control units are connected to the high-bit-rate network by a radio and each of the first and second control units comprises a memory for storing video data transmitted on the high-bit-rate network.

27. The seat of claim 19, further comprising a third pack housing a network repeater for connecting the first and second control units to the high-bit-rate network and a power source for powering said at least one node, the first and second control units.

28. The seat of claim 27, wherein the third pack is positioned within a frame of one of legs of the seat.

29. The seat of claim 19, wherein the screen is positioned in the back of a front neighboring seat.
