Utility model registration for seats for office swivel chairs in particular

The previously common seats have the disadvantage that they can only sit optimally, i.e. in a way that is adapted to the work-psychological conditions, in a certain sitting position allow and (or) an adaptation to changing sitting behavior only through complicated adjustment mechanisms which experience shows that in practice they are rarely used or not at all.

The most important and most common sitting positions are the front, middle and rear sitting postures. The different "positions" of the thighs and buttocks in the seat postures mentioned are taken into account in the new seat surface solely through the shape of the seat surface, which automatically adapts to the circumstances of sitting in the respective position.

In the drawing, this seat is in Figure 1 in section A-B from Figure tivisch.
