Aircraft seat with shared control architecture
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 keyboard ( 17.1 ) and the node ( 11 - 15 ).
1. Aircraft comprising:
a common network bus,
a plurality of seats, each seat comprising:
a screen,
a control unit which controls the screen,
the control unit comprising a data memory in which audio and video data is stored,
the control unit being connected to the common network bus,
a reader connected to the common network bus,
the transfer of audio and/or video data from the reader to the data memory of some or all of the control units of the seats of the aircraft being done through the common network bus.
2. Aircraft according to claim 1 , wherein the common network bus is a common Ethernet bus.
3. Aircraft according to claim 1 , wherein the transfer of audio and/or video data is achieved by a physical link.
4. Aircraft according to claim 1 , wherein the transfer of audio and/or video data is achieved by wireless link.
5. Aircraft according to claim 1 , wherein at least one of the data memories is shared with control units of plural seats for redundancy.
6. Seat comprising:
a screen,
a control unit which controls the screen,
the control unit comprising a data memory in which audio and video data is stored,
the control unit being connected to a common network bus in relation with a reader,
the transfer of audio and/or video data from the reader to the data memory of some or all the control unit being done through the common network bus.
7. Aircraft according to claim 3 in which the physical link comprises an optical link.
