Definitions
- the present invention relates to a chair with at least one seat plate and at least one arranged on at least one support arm backrest, wherein the seat plate is supported on at least one connected to the support arm elongated bending spring and the bending spring is arranged so that it is transverse to the load on the seat plate Elongation is elastically deflectable.
- so-called synchronous mechanisms are known for seating furniture, in particular office chairs. These allow the backrest of the user simultaneous pivoting of the backrest and the seat takes place, wherein the pivot angle of the backrest is greater than that of the seat.
- the DE 196 07 136 shows an office chair with such a synchronous mechanism, which requires a relatively large number of pivot or pivot joints and a longitudinally acting spring. Although the construction revealed there ensures good ergonomics, the construction of this chair is relatively complex.
- an office chair is known in which an elongated bending spring is deflected transversely in the form of a spring package.
- This spring assembly is bolted to a carrier housing, which in turn is connected to the support arm supporting the backrest via a pivot joint. Also, this construction is relatively expensive in terms of the number of items and thus the cost of assembly.
- Object of the present invention is to improve a generic seating to the effect that the required for its construction number of parts and thus the cost of assembly is reduced.
- the seating furniture has a support, at least one seat panel and at least one backrest arranged on at least one support arm.
- the seat plate is supported on at least one longitudinally extending bending spring connected to the carrier arm.
- the bending spring is arranged so that it is elastically deflectable when loaded the seat plate transversely to its longitudinal extent.
- a rotationally fixed fixation of the spiral spring is provided on the support arm, ie a direct connection of spiral spring and support arm without the interposition of rotary or pivot joints or other, a relative movement between bending spring and support arm permitting components. It can thereby be saved between the torsion or pivot axes and their guides between the bending spring and the support arm associated with the rotary or pivot joints, resulting in a simple construction and a saving of parts.
- the production of a chair with good ergonomics and synchronous mechanism is possible.
- the transverse spring that is to say deflectable transversely to its longitudinal extent, advantageously has a greater elasticity than the carrier arm. This means that the bending spring is deflected more elastically with the same torque than the carrier arm and thus the elasticity of the mechanism formed thereby is provided essentially by the spiral spring.
