Definitions

  • the invention relates to a chair according to the preamble of claim 1.
  • the invention has for its object to design a chair of the type presupposed as known so that the position and inclination of the front seat part are changed with a changed backrest inclination and, moreover, when pivoting the backrest a substantially constant distance from the Rear edge of the rear seat part is observed.
  • the chair according to the invention ensures that the distance of the seat from the backrest remains practically the same over the entire swivel range.
  • the lower chair part 2 is designed as a chair column.
  • the chair seat consists of a front seat part 6 and a rear seat part 8 pivotally connected to the rear end thereof via a joint.
  • the front seat part is connected via a bearing 9 to a link 11 which is connected to the seat support 1 via a bearing 10.
  • a force accumulator 13 engages on the bearing 9, and its other end is connected to the seat support 1 via the bearing 13a.
  • the rear seat part 8 is designed in its basic form as an angle lever and has an extension 8a which is articulated via a bearing 12 on the seat support 1 or on the upper region of the chair base frame 2. Between the joint 7 and the bearing 12, a bearing 17 is provided, on which a link 16 is articulated.
  • the handlebar 16 is connected via a bearing 15 to an upwardly projecting area 14 of the backrest support 3.
  • the backrest support 3 is designed in the area of the bearing 5 as an angle lever.
  • the backrest and the seat pivoted synchronously therewith can be locked in any desired pivoting position.
