• the voice control sub-unit 217 as an emergency stop actuator can also be connected to egg ner other place. It is thus possible, for example, for the voice control sub-unit 217 to be designed alone or additionally as an external component for a bus arrangement (MFP / Furnibus).

Depending on the recognized keyword, the third voice control sub-unit 219 then controls the NETWORK operating state via the network enable device 103. Particularly in the case of seats 1 which are operated with rechargeable batteries, it is of great importance that a STAND-BY operating state, in this case the power supply, can be activated in order to reduce electrical power which is taken out of the rechargeable battery to a minimum.
