Definitions

  • the invention relates to seating furniture with a seat, which can be rocked about an axis of rotation parallel to the seat, the angle of rotation around the axis of rotation is limited.
  • a piece of seating furniture with a rocking seat is for example known from DE 199 14 643 A1.
  • On one of the floors facing bottom of the seat is in the middle of the Seat surface that extends downwards perpendicular to the seat surface Support tube arranged.
  • the support tube is vertical a pipe element for seating in the area of the floor attached, the longitudinal axis of which is perpendicular to the seat direction and axis of rotation parallel to the seat surface.
  • the Seating direction is the direction in which you look, if you have taken a seat on the seating.
  • the central support tube is parallel to the seat and support extending perpendicular to the tubular element connected, which is a certain distance from the ground. If the ends of the beam hit the ground during a rocking motion touch, a further rotation around the axis of rotation and thus prevents the seating from tipping over. By the As a result, the angle of rotation about the axis of rotation is limited to the carrier.
  • the invention is based on the object of seating create, which has an extended functionality and which is advantageous from an ergonomic point of view.
  • This object is achieved according to the invention by seating with a seat that is parallel to the seat Axis of rotation is rockable, the angle of rotation about the axis of rotation is limited by at least two delimiting elements which both are attached in the area of the seat or of which a first in the area of the seat and a second in the area a backrest is attached, the boundary elements away from the seat towards extend opposite sides of the axis of rotation.
