  • the invention makes it possible to provide a piece of seating furniture with an elastically resilient seat surface that supports dynamic sitting.
  • An ergonomic piece of seating furniture is created in this way, which enables the user to sit lively and in motion.
  • the partial seat surface mounted on the spring component can, for example, be resiliently displaced in all three spatial directions. This is supported by the design of the component body with the base component, the support component, the lateral spring arms and the hollow chamber arrangement.
  • the component body can be a plastic component. Manufacturing the component body from plastic enables cost-effective mass production.
  • the plastic component can be an injection molded component.
  • Injection-moulded components can be produced in large numbers and inexpensively compared to the use of other materials, such as metal.
  • Injection molding technology also makes it possible to flexibly manufacture hollow chamber arrangements with different chamber arrangements and structures.
  • a first fastening device can be arranged on the base component in the region of the lower mounting surface, which is set up to fasten the component body to the seat furniture underframe.
  • the first fastening device can, for example, have openings, openings and/or indentations in the area of the lower mounting surface can be used to mount the spring component on the seat furniture base, for example by means of screw and / or plug connection.

  • a pivot axis can be arranged between opposing component body halves, each of which is associated with a section of the arrangement of hollow chambers, about which the component body halves can be resiliently (ver)pivoted in response to pressure loading.
  • the pivot axis enables the resilient pivoting of the opposing component body halves when pressure is applied. If separate seat components are mounted on the component body halves, these can be resiliently displaced independently of one another and relative to one another when the seat surface is used by a user.
  • the pivot axis can be designed as a multi-dimensional pivot axis, so that the component body halves can be spatially pivoted, for example.
  • a plurality of pivot axes can be formed on the component body of the spring component, each of which enables sections of the component body to be pivoted in one or more dimensions.
  • the pivot axes can be formed by means of the wall structure of the hollow chamber arrangement.
  • the pivot axis can be arranged in the intermediate space at a distance from a plane of the lower mounting surface as well as from a plane of the support surface. approximately in the middle in relation to the overall height / extent transverse to the pivot axis.
  • the pivot axis can be arranged approximately centrally in relation to the overall height of the component body.
  • the pivot axis can also be arranged essentially in the center with respect to the extension of the component body transversely to the pivot axis.
  • the pivot axis can run along a wall section of the arrangement of hollow chambers.
  • the pivot axis can run along a bottom notch formed in the area of the lower mounting surface.
  • a bottom of the indentation (and thus the indentation itself) may extend the full depth of the base member.
  • the notch can be formed symmetrically with respect to a central plane that essentially divides the notch in half.
  • a hollow chamber of the arrangement of hollow chambers can be arranged above the pivot axis.
  • the hollow chamber can be delimited on the cover side by the support component.
  • a bottom of the hollow chamber can simultaneously form a wall section of the bottom notch, for example the bottom of the notch.
  • the hollow chamber can be designed as an open or a closed hollow chamber. This applies in a comparable manner to other hollow chambers of the hollow chamber arrangement between the base component and the support component.
  • the hollow chambers of the hollow chamber arrangement are open in particular on opposite end faces.
  • the support component and/or the base component can have a component surface that tapers at least on one side on the opposite side.
  • the at least one-sided taper can be designed as a bevel.
  • a (possible) spring deflection provided by means of the lateral spring arms in the spring component can be limited with the aid of a spring limiting device in which mutually associated and, for example, oppositely arranged travel limiters are provided, which come into contact with one another when a permitted spring deflection has been covered due to the load.
  • the spring limiting device can be formed on both sides in the spring components of a piece of seating furniture.
  • a further spring component is mounted on the seating furniture base, which is formed separately from the spring component and forms a spring component arrangement with it, for example a symmetrical arrangement of spring components.
  • the spring member assembly is mounted and enabled on the seat base it is to mount a further seat component, which provides at least one further partial seat surface, on the further spring component and/or on the spring component in the region of the mounting surface of the component body, such that a further resilient partial seat surface is provided.
  • the partial seat surface on the seat component and the further partial seat surface on the further seat component together form an overall seat surface of the piece of seating furniture.
  • the seat components can thus be tilted, pivoted or displaced independently of one another in an elastically resilient manner, so that dynamic sitting is supported on the entire seat surface.
  • the seat component and the additional seat component can each be mounted both on the spring component and on the additional spring component.
  • a spacing gap between adjacent seat members may extend transversely to a spacing gap between the spring members forming the spring member assembly, which may consist of two spring members.
  • the seating furniture can be designed as a stool or chair.
  • FIG. 1 shows a section of a piece of seating furniture 1, which is, for example, a stool.
  • Spring components 3 are mounted on a chair base 2, for example by means of screw connections.
  • the seat components 5 each provide a partial seat surface 6 .
  • the seat components 5 with the partial seat surface 6 together form an overall seat surface 7. Due to the assembly of the seat components 5 on the spring components 3, the seat components 5 can be displaced spatially (3 spatial directions) independently of one another in order to provide an ergonomic seat surface that supports dynamic sitting.
  • the two spring components 3 form a spring component arrangement for the seat components 5 which are each mounted on the two spring components 3 .
  • the seat furniture underframe 2 is designed with a central frame column 8, for example.
  • Other embodiments of seating furniture frames can be provided, in particular in connection with a stool or a chair.
