Definitions

  • the present invention relates to an upholstery arrangement for seating furniture, in particular for an office or conference chair, a method for producing such an upholstery arrangement for seating furniture and an office or conference chair.
  • Seat cushions are sometimes attached to a seat structure, mostly using conventional attachment means such as screws or the like.
  • a seat cushion has an upholstered body and an upholstered panel.
  • the upholstered body is connected to the upholstered panel and/or a cover anchored to the upholstered panel.
  • the upholstery panel is then bolted to the seat structure.
  • WO 2005/124055 A2 describes an arrangement for fastening fabric relative to a frame.
  • a compressible band made of rubber, for example, is clamped together with the fabric in a groove of the frame.
  • the groove has an enlarged section.
  • U.S. 3,981,534 describes a frame attached to the side of a seat of a chair, on the underside of which hooks are formed, into which tabs of a metal seat pan, formed by local cutting and reshaping, engage.
  • U.S. 5,195,222 describes a fastening connection between an upholstery cover and a seat support.
  • the upholstery cover is attached to the seat support by snapping a hook profile strip sewn to the cover into projections on the support.
  • JP 3 595953 B2 and the JP 3 017105 B2 describe known seating cushion assemblies.
  • the present invention is based on the object of specifying a seat cushion arrangement that is easy to produce and flexibly configurable, and a corresponding office or conference chair.
  • this object is achieved by a seating furniture upholstery arrangement with the features of patent claim 1 and/or by a method for producing a seat cushion arrangement with the features of patent claim 7 and/or by an office or conference chair with the features of patent claim 9.
  • the knowledge/idea on which the present invention is based is a seating furniture upholstery in the manner of a to design a shell that can be attached to a seat or backrest structure in a form-fitting manner and that can be removed again. This is achieved by comprehensively reaching behind a seat or backrest structure with an undercut on the edge of the shell-like base body.
  • the upholstery on a seat or backrest is modular, reversible and can be assembled and replaced without the use of tools.
  • the base body of the seat cushion is flexibly deformed for this purpose, encompasses the seat or backrest structure and snaps in with its undercut behind the seat or backrest structure, in particular behind an edge of the seat or backrest structure.
  • an undercut is therefore to be understood as meaning a section on an edge of the shell-like structure of a base body that is suitable for reaching behind a seat or backrest structure and is in particular curved inwards.
  • the shell-like structure of the base body is in particular a type of half-shell that continues over the edge, which is designed to cover the top or front of a seat or backrest structure and leaves an underside or back free except for the area behind which the undercut reaches .
  • gripping from behind encompasses gripping from behind on at least several peripheral sections or the entire circumference of the seat or backrest structure in such a way that the base body and the seat or backrest structure are engaged with one another by gripping from behind.
  • the entire circumference of the edge or, in particular in the case of stiffer materials only structurally necessary Sections, such as corners or the like, be provided with an undercut.
  • the solution according to the invention not only enables a simplified assembly of the seat cushion but also enables a simplified production of the same.
  • the entire seat cushion can be produced in a common molding process as an integral two-component part without further assembly steps.
  • a piece of seating furniture in particular an office or conference chair, can in this way be provided with a seating furniture upholstery at a wide variety of points on its seat or backrest structure, provided that the underlying point of the structure allows it to be reached from behind.
  • the edge of the base body is designed in such a way that it continuously surrounds a seat or backrest structure.
  • at least the edge of the base body or the entire base body preferably contains a flexible or elastic material.
  • the undercut can also have an uninterrupted peripheral design.
  • the edge of the base body is divided into several wraparound sections. Accordingly, there are points on the base body separating the grip sections from one another without an edge or with a merely lowered edge. For example, in the case of an angular base area, these wraparound sections can be located in the area of the corners. The undercut is provided in each case on the wraparound sections.
  • the cushion body is provided with a cover that is connected to the base body in the area of the edge.
  • the upholstery body can have a lateral bulge, behind or under which the cover is fastened to the base body.
  • the cover can, for example, be stapled, glued or welded to the base body.
  • the undercut is formed circumferentially on the base body and is designed for continuously circumferential engagement behind the seat or backrest structure.
  • the base body is formed with a flexible material that can be stretched to create a form fit with the seat or backrest structure.
  • the undercut of a base body can also be provided only in sections.
  • the base body can also be made of a stronger material and only be flexible in the area of the undercut such that the undercut can be bent open to create a positive fit of the seat or backrest structure.
  • the base body is designed to be flexible, at least in a region of the undercut, so that the undercut can be reversed, in particular without tools, onto a structure for slipping over the seat or backrest required size can be clamped.
  • the seat cushion can be fitted and replaced without the use of tools and in a particularly simple manner.
  • the base body contains a flexible silicone material at least in the area of the undercut.
  • the entire base body can also be made from the flexible silicone material.
  • a silicone base body can be produced inexpensively in large numbers in an injection molding tool.
  • production from a thermoplastic elastomer would also be conceivable.
  • additive manufacturing methods are also suitable, for example, for producing the base body with the undercut according to the invention.
  • the base body is formed in one piece with the cushion body.
  • it is an inseparable material bond.
  • the number of parts is thus advantageously reduced.
  • the base body is designed as an integral two-component injection molded part. It can therefore be produced in a common tool. Furthermore, a high component quality can be achieved in the injection molding process, which allows the use of the seat cushion produced in this way without post-processing.
  • the base body is designed as a negative mold of a seat surface structure. Furthermore, the cushion body is designed as a seat cushion. In this way, a modularly insertable and exchangeable seat cushion is provided.
  • the base body is designed as a negative form of a backrest structure and the cushion body is designed as a backrest cushion.
  • the base body designed as a negative form of an armrest structure and the upholstery body as an armrest upholstery.
  • the base body is designed as a negative form of a backrest structure and the cushion body is designed as a backrest cushion. In this way, a backrest cushion that can be used in a modular manner and that can be exchanged is provided for different types and areas of backrests.
  • the form-fit attachment is carried out by stretching and elastically deforming the base body at least in a region of the undercut and slipping the base body over the seat or backrest structure.
  • the edge of the base body is brought into engagement with the seat or backrest structure by releasing the tension.
  • an office or conference chair according to the invention can in particular be an office swivel chair or conference swivel chair.
