Function 

The "dynamic seat" system is manufactured in a version for the left and a version for the right seat and includes:

• Filling and exhausting the air cushions of the multicontour seat according to the requirements that are read by the operating switch.
• Saving the actual contour and adjusting stored contours.
• Maintaining adjusted pressure values. The adjusted nominal pressures of the individual cushion areas are controlled continuously.
• The "dynamic lumbar support" function. Starting with the active air cushion the pulsation occurs alternately in both lumbar support duo cushions. After the program is finished, the original cushion pressure is restored. The pulsation occurs in pressure jumps of 50 hPa each, upwards or downwards. The residence time can be parameterized.
• A "vehicle dynamics seat" function, which combines the advantages of a comfortable seat with those of a sports seat. To do this, the lateral support during cornering is improved through an automatic pressure increase of the outside lateral support cushions.

In the

• seating area 1 cushion,
• lumbar support area 4 cushions (2 cushions each coupled),
• lateral area 2 cushions that are coupled with one another can be actuated in the hydraulic unit.

The air supply that is necessary to fill the seat cushions is provided by the pneumatic pump for dynamic seat control (M40/1). The adjusted contours can be stored.
