Definitions
- the present invention relates to a seating furniture component with elastic covering, in particular a backrest of a chair.
- the present invention further relates to such a chair.
- An office swivel chair in addition to the mounted on a seat support seat and a support frame on a backrest. In most cases, this backrest as well as the seat is upholstered. Cushioned backrests should be ergonomically adapted in shape to the back.
- the upholstery of such a backrest usually consists of foams of different degrees of hardness, through which the seating comfort is conditioned.
- the pad is completed by a fleece or mat cover, which is then covered with a textile material, leather or a plastic material.
- Such Chairs are, for example, the office swivel chairs distributed by the company Sedus Stoll AG under "black dot" and "of course".
- a simpler alternative compared to such upholstered backrests alternative represents a net-covered backrest.
- An office swivel chair with backrests with such elastic covering is for example in the German utility model DE 202 16 302 U1 described.
- the mesh materials used in such office chairs have a relatively high elasticity and unlike padded backrests no point elasticity. You must also be particularly firmly clamped to maintain the shape of the net-covered backrest under load.
- a net-covered backrest must support the lumbar region well. At the same time, however, she must not press hard against the back with the lower edge of the net frame due to lack of padding.
- this material In addition to the high tensile strength and elasticity, it must also be breathable and windproof as possible.
- this material must be well dyeable, since especially in office swivel chairs particularly high demands are made on an attractive design. For this reason, the materials used for net-covered backrests are relatively complex and therefore expensive.
- Such chairs with a net-covered backrest are, for example, the office swivel chairs marketed by Sedus Stoll AG under the name of "black dot net” or "open up” with a backrest which is covered with mesh.
- the present invention seeks to provide an inexpensive and nonetheless very stable seating furniture component for a chair.
- this object is achieved by a seating furniture component with the features of claim 1 and / or by a backrest with the features of claim 15.
- the finding underlying the present invention is that it is not necessary in a padding construction, and in particular in a so-called slim padding structure, to provide such a padding cover which on the one hand requires the requirements for the padding covering, such as seating comfort, aesthetics , Haptician properties and the like, and also includes the very high demands on the tensile / compressive stability of the tight padding and elasticity.
- the multi-layer padding construction according to the invention therefore has a front and a back upholstery cover which require the ones required here Have properties such as particularly suitable haptic properties, Wegelleeigenschaften, aesthetic properties and the like.
- This front side or, if necessary, also the back upholstery cover likewise represent the visible side of the upholstery cover.
- the load stability is fulfilled by a specially provided membrane, which is arranged in the intended use in a non-visible area between the front and the back upholstery cover.
- the particular advantage of the present invention consists in the fact that this membrane is used exclusively for load stability and therefore can be optimized exclusively with regard to these properties. Additional properties, such as aesthetic properties, the haptic properties and the like, are not relevant to the membrane and therefore need not be taken into account, especially since this membrane from the outside just not visible or therefore not felt. In this respect, even a comparatively cost-effective solution can be used for such a support membrane.
- the entire upholstery structure can be provided relatively inexpensively due to the separation of the properties, since the respective components of the upholstery structure can each be optimized separately.
- the cover is formed in two parts.
- the two-part cover has a front and a back cover, wherein at least the front cover in an edge region the seating component is sewn to the membrane via at least one seam. It would also be conceivable, alternatively, if the front cover is clamped to the frame. Conceivable, of course, would be another type of attachment, such as a connection of the two covers by (pressure) buttons, zippers or the like.
- the particular advantage of the two-part design of the covers is that different materials for the covers can be used here. For example, the properties of the front cover and the back cover can be optimized specifically for their intended use.
- the front-side visible side which is used for example in the case of a backrest or a chair seat, has a haptic very sophisticated soft surface, is sensitive to friction and in particular is also permeable to air.
- These properties need not necessarily apply to both sides, and in particular not necessarily to the rear side of the display, especially when the seating component is the seat of a chair.
- the cover can be slipped over the frame in a bag-like manner if the cover is made in one piece, e.g. is formed in the form of a bag.
- the cover is made in one piece, e.g. is formed in the form of a bag.
- a particularly simple assembly is possible.
- the replacement of the cover is also very easy, for example, when the cover must be cleaned.
- the membrane is completely covered by the cover.
- the membrane is net-shaped, mesh-shaped or v technicallyförmig.
- reticulated or reticulated materials are, for example, those of Gabriel under the brand name Runner or Harlequin distributed substances.
- the membrane may be woven or otherwise made.
- At least the front cover is made of a functional textile, in particular breathable material.
- both covers that is, the front and back cover, as well as the membrane of the functional fabric material.
- Functional textiles are textiles of fibers, yarns, fabrics, knitted fabrics and the like with functional added value. These functional added-value properties preferably relate to the breathability. Other functional properties may include windproof, waterproof, thermoregulation, stain resistance, UV resistance, elasticity, durability, etc. In addition, the warming or cooling property can also be considered as functional properties.
- the breathability is the particularly preferred property to improve the seating comfort of a person sitting on the chair.
- Breathability refers to the ability to release water vapor released, for example, from the body of a person sitting on the chair. It is particularly preferred when using those materials which allow 30-300 g of water vapor to escape per hour from S.8. Well-known brand names for functional textiles with good breathability are for example GORE-TEX or Sympatex. In addition, it is also advantageous if materials are used which are in particular windproof, for example, in the case of a membrane-covered backrest to avoid hypothermia of the back of the person sitting on the chair. Finally, it is particularly advantageous for seats of a chair, if hard-wearing, the wear-avoiding or reducing materials are used.
- the membrane is designed as a load-bearing, tensile and pressure-resistant plastic net, plastic fiber fabric, metal mesh, metal fiber fabric and / or mesh of fiber-reinforced material, such as CFK or GFRP.
- plastic-formed membranes they may be made of any man-made fibers or polymers, such as PET (polyethylene terephthalate), which have versatile properties and therefore constitute a preferred synthetic fiber.
- PET polyethylene terephthalate
- Polyester fiber (PES) are very tear and scuff resistant, but absorb hardly any moisture.
- Particularly advantageous is the design of the membrane made of polyamide (PA), such as nylon, nylon, etc., which are very elastic and tensile.
- plastic materials such as polyimide (PI), polyamide-imide (PAI), polyvinylsulfide (PPS), aramid, and the like can be used, depending on which properties are desired.
- PI polyimide
- PAI polyamide-imide
- PPS polyvinylsulfide
- aramid aramid
- materials such as polytetrafluoroethylene (PTFE) can be used, which are very temperature resistant, chemically largely inert and water-repellent and is used for example under the trade name GORE-TEX.
- PTFE polytetrafluoroethylene
- This material is preferably used for the cover, but can also be used for the membrane.
- PE polyethylene
- PP polypropylene
- the latter fiber is a very light textile fiber and also has a high elasticity.
- glass fiber reinforced materials GRP
- carbon fiber reinforced can also be used Use plastics (CFRP), which are also very light and have a very high strength.
- plastic materials just mentioned especially for the membrane, it is also possible to use very simple metal nets, metal mesh and the like, since these fabrics are not visible and therefore do not have to have a particularly appealing appearance.
- metal nets can also use networks of ceramic fibers or ceramic-containing materials.
- the frame has a clip bar.
- This clip strip forms the attachment interface of the seating furniture component and is designed for this purpose to be clipped into a correspondingly formed attachment interface of the seat.
- a welt strip can also be used.
- This clip strip or the welt strip is formed elastically deformable in the rule, but at least ensures a certain dimensional stability for the seating furniture component, unless this seating furniture component has its own dimensionally stable frame. Due to their nature, this clip strip or the welt strip can be clipped into or hung in a specially provided attachment interface of a frame of the chair. In this way, a very elegant and nonetheless very stable attachment of the seating furniture component is guaranteed to the seating.
- the clip strip or the piping strip due to their, in comparison to a conventional dimensionally stable frame, much thinner expression suitable for imparting a very light appearance to the seating. This is especially from design technical For reasons of particular advantage, nevertheless a high stability of the seat is guaranteed due to the thin but dimensionally stable frame nonetheless.
- the seating furniture component is designed as a backrest.
- the seating furniture component has a backrest support, via which the backrest is fastened to a seat support of the seat.
- the inventive design of the upholstery structure consisting of cover and membrane is particularly elegant here.
- the visible cover is used for design-technical reasons optimizable external appearance. This cover can therefore be optimized with regard to these properties and in particular with regard to the breathability, abrasion resistance, haptic properties and the like.
- the essential for the load on the backrest properties of elasticity and tensile and compressive strength are met by the hidden so to speak inside the cover and thus not visible membrane.
- This membrane can therefore be optimized exclusively for these properties, so that much more cost-effective materials can be used for this membrane.
- optical properties play no role here. This gives a backrest that has a very thin and nonetheless very appealing appearance and also provides the required tensile and compressive strength. Particularly preferred is this type of backrest, provided it is equipped with a Slim-upholstery.
- the frame is formed dimensionally stable and forms the back frame of the backrest.
- the frame is formed by the attachment interface of the seating furniture component, which is clipped or suspended in the backrest support. In this way, it is possible to realize a very thin, seemingly massive frame, so that the entire backrest shows a particularly light-looking appearance. This is particularly advantageous when the frame of the backrest is visible.
- the rear cover and the membrane only extend to an inner edge region of the seating furniture component. There they are attached to the front cover, for example sewn over a seam.
- the seating furniture component in the outer edge region then has only the thickness of the front cover.
- the attachment interface which is designed for example as Kedermann or clip bar, fasten.
- the so-formed upholstery cover can thus be clipped or hooked directly from the front or from the back directly to a thin backrest frame of the chair.
- the possibly less attractive membrane or the possibly less high-quality rear cover is not visible from the front side, that is to say from the visible side or the side of the front cover. Nevertheless, the stability is ensured because the various covers and the membrane are sewn together or otherwise secured together.
- the seating furniture component is designed as a flat cushion, in particular as a backrest with a flat cushion.
- the seating component inside a thin foam layer, which is arranged in the interior of the seating furniture component between the front and rear cover, and preferably between the front cover and the membrane.
- this flat upholstered seating component has a lot to offer much thinner appearance and thus works much easier, which is advantageous for design reasons.
- At least the membrane in a inner region of the seating furniture component has a higher elasticity than in an edge region of the seating furniture component, to which it is attached, for example, to a frame.
- at least one or even both covers have the same properties, that is to say that they have a higher elasticity in an inner area of the seating furniture component than in an edge area. This is particularly advantageous when the seating component is, for example, the seat or the backrest of a chair, which is loaded in the intended use of a person sitting on the chair, preferably in the inner region of the seating furniture component. Also for reasons of comfort, this may be advantageous when e.g. if too hard a seat or too hard backrest should be avoided.
