Abstract

A pneumatic seat device, in particular a pneumatic seat device for aircraft, includes at least one pneumatic unit and first and second computer units, whereby an advantageous division of tasks and/or functions within the pneumatic seat device among the individual computing units can be achieved. Primarily, it is thereby possible to obtain effective and fast data processing with use of the two computing units and, consequently, fast control and/or regulation of the pneumatic seat device.

Claims

1. A pneumatic seat device for aircraft, comprising:

a plurality of pneumatic units, wherein each pneumatic unit has at least one pneumatic cushion that has at least one air chamber that can be inflated with air;

at least one computing unit of a first type;

a plurality of computing units of a second type, which are assigned to the plurality of pneumatic units, respectively; and

a data network comprising a data bus that

provides for an exchange of data between the plurality of computing units of the second type and the at least one computing unit of the first type, and

further provides for exchange of data among the plurality of computing units of the second type, wherein

at least the plurality of computing units of the second type control air pressure in each of the plurality of pneumatic units.

2. The pneumatic seat device as claimed in claim 1, wherein

the plurality of computing units of the second type are arranged with the at least one computing unit of the first type in distributed fashion.

3. The pneumatic seat device as claimed in claim 1, wherein

at least one data unit is provided for wireless reception and/or for wireless transmission of data.

4. The pneumatic seat device as claimed in claim 1, wherein

the at least one computing unit of the first type is a central computing unit, and the plurality of computing units of the second type are decentralized computing units.

5. The pneumatic seat device as claimed in claim 4, wherein the decentralized computing units each comprise a decentralized memory unit.

6. The pneumatic seat device as claimed in claim 4, wherein a valve unit and a sensor unit are connected to each of the decentralized computing units.

7. The pneumatic seat device as claimed in claim 1, further comprising

at least two memory units.

8. The pneumatic seat device as claimed in claim 1, further comprising:

a pump; and

a transfer unit formed by a compressed air line, wherein

the compressed air line enables there to be transfer of air between the pump and the plurality of pneumatic units and also among individual pneumatic units among the plurality of pneumatic units.
