Abstract
Joint arrangement () has a hollow cylindrical receiving cylinder () that extends in a cylinder axis direction (Z) and receives one end of a chair column () of an active-dynamic wobble chair, the latter movably mounted in a substantially hollow cylindrical outer joint shell () composed of joint shell segments (). Movable mounting of receiving cylinder () is achieved by deformable elastic elements () arranged to be variable in shape and position in a bearing gap () between an outer wall portion () of the receiving cylinder () and an inner wall portion () of the joint shell (). Receiving cylinder () is actuated in a force-dependent manner, whereby shape and/or position of the elastic elements () change as viewed in a radial direction (Rs) from changing, preferably reducing, clearance of the bearing gap () when the receiving cylinder () is actuated in a cylinder axis direction (Z).
