  • the preamble of claim 1 features specified, as from the DE 198 10 768 A1 or based on an earlier application by the applicant DE 101 25 994 A1 are known.
  • Assemblies in the seat substructure are called "synchronous mechanics" of an office chair understood for a coupled, a certain relative movement of the seat and backrest to each other associated kinematics.
  • On the seat support is the usually office chair with a padded seat assembled.
  • the backrest support which differs commonly from the actual synchro mechanism extends to the rear, carries on to one the arm of the office chair runs at the top.
  • Seat support and backrest support are articulated so that a Swiveling movement of the backrest to the rear - as for example caused by the chair user leaning against the backrest can be - a lowering movement of the rear edge of the seat down induced.
  • This correlated seat-backrest movement brings you considerable comfort advantage and is for orthopedic reasons he wishes.
  • the spring arrangement provided in the construction according to DE 101 25 994 A1 is based on two leg springs housed in the base support are.
  • One leg of the spring is in an adjustment arrangement in the base support housed, whereas the second leg upwards in the direction

  • the support the helical compression spring towards the seat support is improved, because due to the movement of the seat support plate towards the bottom down an actuation of the synchronous mechanism a certain swivel angle in balance the support of the helical compression spring.
  • Further preferred embodiments relate to the training the bearing head of the respective abutment boom in the form of a frame, on the one hand for the storage of the abutment boom on the base beam and on the other hand as a contact surface for the eccentric cam of the control shaft is used.
  • At least one is An additional abutment is provided at the rear end, which is adjustable in the longitudinal direction of the seat. This allows the on this abutment boom sitting helical compression spring in its basic preload can be varied so that together with the adjustability of the abutment boom itself at least two different counterforce ranges to adapt the synchronous mechanism to light or heavyweight people are made available. Within this Areas can then be adjusted via the actual adjustment of the abutment boom a fine adjustment can be made.
