  • a coating layer is injected, which is the compound fixed.
  • it is not exactly defined beforehand on which meshes of the net fabric the connecting cylinders engage in the net fabric.
  • the mesh is permanently connected to the frame after encapsulation.
  • the present invention seeks to provide an improved frame arrangement for office seating.
  • the idea on which the present invention is based is to fasten a covering membrane to a clamping frame by means of a clamping strip in such a way that a pretensioning force of the covering membrane is supported on a stop provided between the clamping strip and the clamping frame.
  • the terminal block is locked in such a way with the clamping frame, that also based on the terminal block moments are also supported on the stop.
  • the particular advantage consists in the self-helping design of this frame assembly.
  • the stopper is designed so that the biasing force does not act releasably on the latching connection of the latching means of the clamping frame and the terminal block.
  • the biasing force largely relies on the stop.
  • a stable attachment of the covering membrane is ensured, wherein the connection of the locking means of forces which are operationally initiated by a person sitting on the chair, remains virtually unaffected.
  • a self-retaining construction for the clamping of the string membrane is thus provided.
  • a frame arrangement which provides a detachable connection of the covering membrane with the clamping frame.
  • the string membrane can be replaced or removed, for example, for cleaning and reattached.

  • the Kederelement With the Kederelement a defined section is provided on which the string membrane is attached.
  • the string membrane is connected to the terminal block, in particular by material connection.
  • the terminal block itself represents the defined section to which the string membrane, in particular directly and firmly, is attached. Also, operator errors when attaching the string membrane are avoided on the clamping frame.
  • the Kederelement is designed as a flat profile strip, wherein the covering membrane is mounted in the region of a first profile edge on a first flat side of the flat profile.
  • the Kederelement may comprise a plastic strip to which the covering membrane is sewn and / or glued.
  • the covering membrane may also be welded to the flat profiled strip or otherwise connected in a form-fitting, cohesive or non-positively connected manner.
  • the Kederelement is supported in the clamped state with the first profile edge on the clamping frame and supported with a second profile edge of a second flat side of the terminal block.
  • the biasing force transmitted from the stringing membrane to the piping member becomes attached to the frame assembly and to the clamping frame, respectively and the terminal block supported.

  • additional facilities on Kederelement for supporting the same such as heels or the like, of course, conceivable.
  • the Kederelement is in the mounted state in the clamping groove of the clamping frame, in which the terminal strip engages at least in sections.
  • the Kederelement is clamped in a state in which the first profile edge to which the string membrane is attached, against the clamping frame by the biasing force and the corresponding deflection of the string membrane via an envelope attachment, is pressed.
  • the Kederelement bears with the second profile edge on the terminal strip and forms there a pivot point or pole and / or jammed with a narrow side of the Kederelements in a rounding or recess of the terminal block.
  • the covering membrane and the fastening section are designed such that they can be welded together, in particular by means of a laser beam welding method.
  • a solid, cohesive connection between the covering membrane and the fastening region of the terminal strip is created in a manner that can be automated very easily.
  • the materials of the clamping strip and the covering membrane are preferably thermoplastics that are compatible with one another by welding technology. In the case of using a laser beam welding process, both heat conduction welding processes and deep welding processes can be used.
  • the clamping frame is formed as a supporting structural part of the frame assembly.
  • an extremely slim frame arrangement is achieved, in particular in the case of a membrane backrest, which opens up new possibilities in the design of the membrane backrest.
  • the designer thus has the advantageous opportunity to make the appearance of the frame arrangement very filigree, which allows a particularly elegant appearance and appearance.
  • the clamping frame simultaneously represents the supporting structural part of the frame assembly reduces the number of parts used and provides functional integration. Thus, the total manufacturing cost of the frame assembly can be reduced because fewer parts must be manufactured, handled and assembled.
  • the clamping frame contains a multidirectional fiber composite material.
  • a multidirectional fiber composite material has a particularly high strength, whereby the dimensioning of the clamping frame can be significantly reduced and thus an advantageous narrow or filigree optics of the clamping frame can be achieved.
  • the haptic appearance of such a multidirectional fiber composite material and the optics are appealing.
  • such a multidirectional fiber composite material in particular when it comes to fiber fabrics, can be produced very easily automatically, which lowers the production costs in comparison to manual production, particularly in the case of high quantities.

  • a solid wood material or a wood composite material or a different kind of composite material for the clamping frame in question are examples of a metal part, for example in the form of an aluminum profile, in particular an extruded aluminum profile.
  • the clamping frame of the frame arrangement is formed as a profile with curve regions which runs around with a substantially constant cross-sectional contour.
  • a substantially constant cross-sectional contour is a contour to understand, which can change slightly due to changes in direction of the profile. For example, a radius compensation must be created in a curve region of such a profile, which can lead to slight deviations of the cross-sectional contour in the curve areas.
  • the essentially constant cross-sectional contour also encompasses fastening elements or devices which can deviate the cross-sectional contour in this section from the other cross-sectional contour of the profile.
  • the entire clamping frame can in particular be formed in one piece, which in turn greatly reduces the number of parts.
  • a particularly easy-to-install solution for attaching the covering material can thus be realized in the curve area.
  • This is usually problematic when stringing office seating furniture because a covering material in the area of corners slightly curls or wrinkles.
  • With the present invention can be provided with the prefabricated attached to the covering material Kederelement optimally designed with its mechanical stress conditions covering material, so that the final assembly of attaching the covering membrane by clamping the Kederelements between clamping frame and terminal block with the prefabricated covering material is easy to do.

  • the region of the undercut is almost free of forces caused by the moment, whereby the holding force of the clamping strip (as a reaction force on the biasing force) is supported on the stopper area and not on the locking means or the spring of the clamping frame. This ensures that the connection between the terminal block and the clamping frame is not affected by operating forces, i. by tension or bias of the string membrane, is influenced.
  • the terminal strip on a Umtschvorsprung on which the string membrane turned over is provided.
  • the terminal strip additionally in the region of the Umtschvorsprungs an oriented in the direction of the clamping frame projection nose, which forms an undercut together with the locking bar.
  • the keder element can be supported on this undercut and thus secured.
