Abstract
The invention relates to a method for monitoring the pressure in a device for the pneumatic adjustment of a seat in a transportation means, in particular in a motor vehicle. The device comprises a plurality of cushions () which are able to be filled with air and which are connected via respective valves () to a common preliminary pressure volume (), wherein a pressure sensor () is provided for measuring the pressure (p) in the preliminary pressure volume () and the preliminary pressure volume () is coupled to a compressor () for supplying compressed air without a non-return valve being connected therebetween. For the purpose of monitoring the pressure in a respective cushion (), a predefined pressure is set in the preliminary pressure volume by way of operation of the compressor () and/or by way of air discharge from the preliminary pressure volume () via at least one leak, with the valve () between the respective cushion () and the preliminary pressure volume () closed, wherein the predefined pressure deviates from a target pressure (p, p, . . . , p) in the respective cushion () by at most 10% of the target pressure and/or at most 50 hPa. After the setting of the predefined pressure, the valve () between the respective cushion () and the preliminary pressure volume () is opened and the pressure in the preliminary pressure volume () is measured via the pressure sensor (). If the measured pressure (p) deviates from the target pressure (p, p, . . . , p), the measured pressure (p) is set to the target pressure (p, p, . . . , p) by way of operation of the compressor () and/or by way of air discharge from the preliminary pressure volume () via the at least one leak.
