Device for pneumatically adjusting a seat in a means of transport

A device for pneumatic adjustment of a seat in a transport, the transport comprising one or more cushions which can be filled with air and which are connected via one or more valves to a compressed-air supply, the device comprising:

• the one or more valves and
• a control device configured to actuate the one or more valves to change a filling state of the one or more cushions, wherein
• a respective valve of at least some of the one or more valves comprises one or more actuation elements comprised of an electroactive polymer, to which an electrical voltage can be applied, wherein, by application of the electrical voltage, a respective actuation element is deformed, so that one or more passage openings via which an exchange of compressed air with at least one cushion takes place is or are opened or shut off;
• wherein the one or more actuation elements of the at least one valve is or are each formed from a wound dielectric elastomer foil, the wound dielectric elastomer foil being a cylinder wherein application of the electrical voltage causes a diameter of the cylinder to be reduced and thus open the one or more passage openings.
