  • the invention relates in particular to an active dynamic seating with a twist.
  • DE-GM 731114 describes an active dynamic seating device with a seat part, which is connected via a first tilting joint with a support shaft, wherein the support shaft is in turn articulated by means of a second tilting joint on the foot part of the seat device.
  • each tilting joint preferably consists of a respective cap formed at the end of the support shaft, which is guided in a hollow cylinder and acted upon by a helical spring arranged in the hollow cylinder.
  • This seat device is known from the document DE-GM 1829791.
  • This seat device is designed as a pendulum chair and therefore has a back and forth swivel seat.
  • the seat itself is rigidly connected to an intermediate piece and a foot part, wherein the intermediate piece is pivotally mounted on the foot part.
  • This Einbeinsitz includes a footboard, an intermediate piece and a Seat part. Between the foot part and the intermediate piece a spring element is arranged, which allows a swinging or swinging of the intermediate piece with the seat part from the normal position. This allows the seat occupant to oscillate back and forth between the normal position and the deflected position.
  • a seating furniture is proposed with a device for defining a reverse direction R, in which the pendulum joint is deflected differently depending on the relative deflection direction for orientation of the device and wherein a safety device is provided, which has a lower. limited deflection of the pendulum column in the reverse direction allows, as is the case in other directions.
  • active dynamic seating furniture therefore allows a limited pendulum movement in at least one direction, in particular in a direction to the rear. If such seating furniture comprises e.g. With a backrest and a seated user leaning against the seatback, the seat can make only a slight backward deflection, thereby ensuring that the user does not tip over or over.
