Definitions

  • the invention relates to a device for synchronous adjustment of the seat and backrest of a chair to the posture of a user according to the generic term of claim 1.
  • DE 197 29 330 A1 describes a chair with a device for synchronous adjustment known from the seat and backrest to the posture of a user, at which a front support designed as a pendulum joint the seat of the chair connects to a base and between the backrest and base and a rotary connection is arranged between the backrest and the seat, the backrest of a return device, not shown, the Restoring forces can be realized by spring forces is applied.
  • the seat is thus swinging.
  • the reset device is a torsion spring in the backrest spherical bearing.
  • the spring force of the torsion spring is below in the underframe
  • the center of the seat is adjustable.
  • the disadvantage of this facility is that because of their arrangement below the seat difficult to access and therefore difficult to use.
  • the invention tries to avoid these disadvantages. It is based on the task a device for synchronous adjustment of the seat and backrest To create chairs to the posture of a user, which in its restoring effect is easily and quickly adjustable, a large swivel range of the backrest and has an ergonomically favorable movement sequence.
  • the advantages of the invention are that the pivoting range of the backrest Compared to the known prior art, since the torsion spring only the relative swivel between the seat and backrest must accommodate and The device is ergonomically favorable because the backrest support is in a circular orbit of the pendulum joint swivels and thus an extremely good adjustment the movement of the seat and backrest against the back and pelvic contour of the user is achieved.
  • the torsion spring is arranged axially in the rear seat shell joint is and via a bracket and tensioning element with the device for adjustment the restoring forces is connected, this device in the rear area arranged near the backrest and laterally below the seat of the Chair is operable. This will allow quick and easy operation of the facility allows to adjust the restoring forces.
  • the pendulum joint on a fixed axis in the Stand column receiving housing is suspended and as a rotatable connecting element connected to a connecting axis of the right and left back support which is a when the seat and backrest rotate Circular orbit. This ensures an optimal adjustment of the backrest to the user's back contour movement.
  • Fig. 1 shows a side view of a chair with the device according to the invention for synchronous adjustment of the seat and backrest to the posture of a user, while in Fig. 2 the device in perspective as a plan view is shown.
  • Fig. 2 shows the device in perspective as a plan view is shown.
  • the chair consists essentially of a seat 1, a backrest 2, one central column 3, a backrest support 4 and a column support housing 5, and a front seat pan joint 6, a rear seat pan joint 7, a reset device in the form of a torsion spring 8, a device for adjusting the restoring forces 9 and a pendulum joint 10.
  • the front seat pan joint 6 is a swivel joint for the seat 1, which also is connected to the column support housing 5.
  • the rear Seat shell joint 7 is connected to the backrest support 4 and serves as a swivel joint for the backrest 2.
  • a torsion spring 8 is arranged axially in the rear seat shell joint 7.
  • the torsion spring 8 causes a restoring force between the seat 1 and Backrest 2. It is equipped with the device for adjusting the restoring forces (spring force adjustment) 9 via a wedge-shaped mounting and tensioning element 11 connected, the device 9 in the rear area of the backrest support 4 is arranged near the backrest 2.
  • the pendulum joint 10 provides a rotatable connecting element between one fixed axis 12 and a backrest connecting axis 13, which connects the left and right back support 4, it is between the front Seat shell joint 6 and the rear seat shell joint 7 (or the torsion spring 8) arranged and assigned to the backrest support 4.
  • the invention is not based on the described embodiment limited. So z. B. the torsion spring 8 in the rear seat pan joint 7 by a second torsion spring 8 can be added to the front seat pan joint 6. A Another possibility is a torsion spring only in the front seat pan joint 6 8 to bring.
