ABSTRACT:
An active dynamic seat has a base, an intermediate piece linked to the base and a seat part linked to the intermediate piece. The seat part can tilt in all lateral directions and is linked in an essentially fixed manner in the vertical direction to the intermediate piece. One or more restoring devices act on the seat part. The intermediate piece is fixed at its lower end to the base and is resilient in the vertical direction. In another embodiment of the invention, the seat part is linked to the intermediate piece by several spring strips distributed around the periphery of the seat part and of the intermediate piece.
