DE8807017U1 - Upholstery for seating, reclining furniture, etc. - Google Patents

Description

The invention is directed to an upholstered part of the type specified in the preamble of claim 1. Such an upholstered part can be manufactured separately and later, when in use, used as a support for a piece of seating or reclining furniture. Such a support can then be optionally connected to the piece of furniture or removed from it. The covering material covers the upholstered part on both sides.

Alternatively, such an upholstered part can also be structurally connected to the seating or reclining furniture intended for it. As a rule, the covering material then only spans the visible side of this structural unit and is connected to the furniture at the edges.

The well-known upholstered part usually has a multi-layered filling. An upper and lower layer of nonwoven fabric is placed over a core layer of foam, which is responsible for the elasticity of the upholstered part, which together with the core layer create the filling of the upholstered part and over which a layer of the cover material is then placed on the top and bottom. The two layers of cover material are sewn together along the outline of the filling. To prevent the enveloping cover material from slipping on its filling, the two layers of cover material are sewn through the filling at points and the sewing points are reinforced with buttons. A similar procedure is used for upholstered parts that are integrated into the seating or reclining furniture, so that one then ends up with a layer of cover material on the front side, which is connected to the furniture around the edge of the filling by gluing, stapling or nailing. The production, storage and processing of the various layers

the filling and the covering with the cover material are cumbersome and require difficult logistics. The upholstery physiology of the well-known product is unsatisfactory because when the upholstery part is used as intended, the pores in the foam close due to the body weight and lead to poor ventilation. Furthermore, the layers of the filling easily give way when in use and do not provide the body with sufficient lateral support. The flexibility of the molded part only results in a corresponding elastic change in the volume of the filling, while the cover material above it is not affected and therefore wrinkles. The cleaning of the upholstery part, which is necessary after prolonged use, is problematic and usually does not allow for a simple washing process. As the filling ages, there is also a permanent change in volume, which leads to an undesirable so-called fluttering of the cover material. The foam material tends to crumble and the fleeces fray and experience a permanent compression of the fleece thickness after prolonged use.

The invention is based on the task of developing a molded part of the type mentioned in the preamble of claim 1 that is easy and inexpensive to produce, which remains dimensionally stable even after prolonged use, provides good support for the body resting on it, is easy to clean and remains firm even after intensive use. This is achieved according to the invention by the measures mentioned in the characterizing part of claim 1, which have the following special significance:

The upholstery filling is a specially constructed fleece, which consists of thermo-fusion-fabrics,

'; B I.., ; ra:->üii. Such binding fibers are known as so-called core-sheath fibers, the sheath material of which, under the influence of heat, leads to the mutual bonding of the fibers in the filling and therefore results in a form-elastic product that is referred to as "voluminous nonwoven fabric". This special nonwoven fabric is pressed into a certain relief, which creates the desired, body-friendly sitting or lying surface. The relief is frozen in the form of a spruce and the binding fibers connected to one another. The voluminous areas of the relief retain an ideal elastic flexibility. The resulting upholstered part can be used without a cover material. If necessary, it can also be placed in a cover made of cover material or, when used as an integrated part of the seating or reclining furniture, covered with the cover material, which is then attached directly to the furniture by nailing, gluing or stapling.

However, it is particularly advantageous, according to claim 2, to press-form the later cover material together with the binder fiber nonwoven fabric, whereby the thermo-fusible binding fibers create a firm bond not only with each other, but also with the cover material, thereby fixing the relief. The dimensional stability is achieved by a large number of bonding points within the nonwoven fabric and between the nonwoven fabric and the cover material. Both materials are attached to each other both vertically and horizontally in accordance with the relief profile. The otherwise required assembly of the known upholstery part is eliminated. This results in easy cleaning of the soiled upholstery molded part, ve:- 6e.r water content of such a product is low i

According to claim 5, the fibers are preferably made of flexible material, which is why they bend like a rod due to the relief contour and therefore provide the ideal elasticity of shape mentioned, which also provides lateral support for the body. The airy structure of the product according to the invention is beneficial for the physiological properties of the upholstery because there is good heat and moisture exchange. Folding or shifting of the cover material on the upholstery filling is impossible due to the mutual connection between the cover material and the binding fibers.

Further measures and advantages of the invention emerge from the subclaims and the following description and the drawings. The invention extends to all new features that can be derived therefrom, even if these are not expressly mentioned in the claims. They show:

Fig. 9 shows a cross-section through a binding fiber used in the upholstery molding according to the invention in a highly magnified view.

As can be seen from Fig. 1 and 2, the upholstery molding 10 according to the invention consists of a profiled filling Ii, which is provided with a covering material 20 on both its visible side 12 and its rear side 13. There is a uniform filling 11 of a special type, the appearance and properties of which can best be seen from Fig. 3 and 4.

According to Fig. 3, there is initially a fiber fleece 14 that is formed from a homogeneous mixture of two types of fibers 15, 15', both of which are made of flexible material but have a different structure. One type of fiber is binding fibers 15, which are made from a polyester core and a sheath of copolyesters. The other type consists of normal fibers 15', the material of which is polyester. A mixture of 30% binding fibers 15 and 70% normal fibers 15' has proven to be very effective. The proportion of binding fibers 15 can also vary in the range between 15 and 40%. Both fibers 15, 15' should, however, be of the same system, for which polyester was chosen in this case. The fiber fleece 14 produced in this way, according to Fig. 3, has a surface weight of approximately 1500 g per m , which results from the apparent fleece height 16. The

The structure of the binding fiber 15 is illustrated in Fig. 9 with its fiber sheath 18 enveloping the fiber core 17. The fiber fleece 14 contains such a homogeneous mixture that the fibers 15, 15' alternate with each other in every direction in their proportional ratio of approximately 1:2 and thus a binding fiber 15 always touches or crosses normal fibers 15*. Such contact points are designated 19 in the schematic representation of Fig. 3.

In a preparatory work step, this fiber fleece 14 is now permeated by hot air, which is dimensioned in terms of temperature, air flow strength and flow duration such that the mentioned sheath material 18 of the binding fibers 15 softens and the mentioned contact points 19 become wet and stick together. This is further enhanced by the fact that, as can be seen from Fig. 4, the thickness of the fleece is reduced to 26 and the contact points 19 between the fibers 15, 15' are thus more clearly defined or newly created. In this compressed state 26, the fiber fleece is now cooled, whereby the materials of the fiber sheath 18, which have flowed into one another in droplets at the contact points mentioned, solidify and create the connections 29 between the fibers 15, 15' shown in Fig. 4. This creates the special character of the product shown in Fig. 4, the fibers of which are cross-linked with one another and form a sintered, air-permeable fiber block, which is referred to in technical terms as a voluminous "nonwoven fabric" 24. The basic appearance is illustrated in more detail in Fig. 4 a. There are two Pairs of fibers 15, 15* connected to each other by a core-sheath material are shown. The connections 29 between the fibers

15, 15' hold them tightly against each other and produce the form elasticity that can be observed in this special nonwoven fabric 24 and that becomes noticeable when loads occur.

This nonwoven fabric 24 is now provided with a covering material 20 on its top and bottom, as shown in Fig. 5. It is perfectly possible to provide such a covering material 20 on only one side of the nonwoven fabric 24. If necessary, a thermoplastic binding agent 21 can also be sprinkled onto the surface of the nonwoven fabric in powder form. This material combination 22 consisting of the outer covering material layers 20, 20 and the nonwoven fabric 24 present as a central layer is now placed between the two halves 31, 32 of a mold 30 consisting of a sieve-shaped material and these mold halves 31, 32 are pressed firmly against one another in the direction of the pressure arrows 33 indicated, as shown in Fig. 5. The mold halves 31, 32 designed as a screen wall have a surface profile that determines a certain relief contour that results from the intended use of the finished molded part 10 as a seat or lounger. When pressed together 33, the corresponding relief is formed not only in a cover material 20, but in the entire material combination of Fig. 5. The fibers in the nonwoven fabric 24 are also deformed accordingly, whereby this deformation is initially elastically flexible and therefore the two mold halves 31, 32 are held firmly together in order to form the relief 34 in the material combination 22. The fibers 15, 15' involved are bent like a rod and penetrate each other according to the compression at the respective point determined by the profile contour. This

is illustrated in Fig. 6 a using the two fiber pairs 15, 15' previously explained in Fig. 4 a, where further contact points 28 are created between the fiber pairs 15, 15' and of course also contact points 27 between the nonwoven fabric 24 and the cover material 20.

Then, as can also be seen from Fig. 5, hot air 23 is sent through the material combination 22 clamped in the mold 30, namely, transversely to the material layers, through the sieve holes of the mold halves 31, 32. This hot air 23 is dimensioned in terms of temperature level, current intensity and flow duration such that the connections 29 between the fibers 15, 15' explained above with reference to Fig. 4 soften again, but in addition the sheath material of the binding fibers 15 also softens at the other contact points 27, 28 mentioned in Fig. 6a and a corresponding wetting occurs. This also applies to the thermoplastic binding agents 21 sprinkled onto the surface of Fig. 5. Once this has been done, the mold 30 remains pressed together and is exposed to a cold air flow 25, which will be explained in more detail later with reference to Fig. 7, which causes the droplets that have flowed into one another at the contact points 27 to 29 to solidify and finally produce point-like solid connections 27, 28, 29 as shown in Fig. 6a. The embossed relief 34 is frozen in the upholstery molded part 10 in this way, which is why this shape is retained when, as can be seen from Fig. 6, the two mold halves 31, 32 are then removed. The cover material 20 is stretched tightly over the relief-like surface of the nonwoven fabric 24 and is inseparably connected to it. The relief structure 34 of the surface exists, like a grain, into the interior of the fleece.

material 24 and is fixed there by a corresponding mutual anchoring of the fibers 15, 15'. As a result, the relief is impressed on all layers of the material combination 22. When the upholstery molded part 10 is used as intended, a load 35 which varies in places is exerted on it, as shown by the pressure arrow, under which the structural unit made of nonwoven fabric Ijnri Be7imefnff 70 cirh rtsiiwincan dof nt-mi ort snfrirnnri Hear •—— y — 3 — j — —

fibers 15, 15' interconnected by their connections 27, 28, 29. The fiber sections between these connections deform and, when the load 35 ceases, automatically return to their original relief shape 34.

It is clear from Fig. 1 and 2 that such a relief 34 as shown in Fig. 6 can never look like in a finished upholstery molding. The upholstery molding 10 has three different, firmly pressed together points 36, 37, 38, whose appearance and function are different. The one pressing point 37 is practically only on the visible side 12 of the upholstery molding 10, is linear, runs through the entire width of the upholstery and divides the molding 10 into two areas, namely a seat area 40 and a backrest area 41. This creates a bent edge at point 37, which allows the two areas 40, 41 to pivot against each other like legs.

In the backrest area 41, pressed together areas are formed at points, both on the front and rear sides 12, 13, including the respective cover material 20, which is why a crater-shaped relief is created there. Button-shaped impressions 36 are created, which look like sewn-in

Buttons work, although these areas are made of the material of the material combination 22 due to extreme compression and caking when the hot air 23 is passed through. Finally, along the circumference 42 of the upholstery molding 10 indicated in Fig. 1 and 1,

be integrated, which are already inserted in the working phase shown in Fig. 3 between two layers of the fiber fleece 14, which together contribute to the fleece height 16 described there. These scaffolding rods are baked into the upholstery molding 10 during the treatment mentioned. Such inserts can be made of plastic and/or metal.

The manufacturing method of the product 10 is, as already mentioned, easy to illustrate with the help of Fig. 7. It is based on two so-called box feeders 45, 45", which feed one of the two aforementioned fiber components 15, 15' to the weighing container 4/, 47' via a needle cloth 46, 46'. To distinguish them, the binding fibers 15 are shown by thick lines in Fig. 7, while the normal fibers 15' are shown by thin lines, although this does not correspond to the actual conditions, at least to this extent. The two weighing containers 47, 47' empty simultaneously onto a correspondingly intermittently moving transport belt 48, whereby the triggering fiber weight is determined according to the proportions of the fibers 15, 15' on both sides. As a result, as indicated in Fig. 7, these Portions in groups on top of each other are brought by the conveyor belt 48 to an opener 50, where a first mixing of the two fibers 15, 15' takes place, before another box feeder follows, into which the already nibbled fibers 15, 15' are transferred together from a needle cloth 52 into its weighing container. From here they go to a conveyor belt 54, which also moves intermittently in time with the weighing container emptying, where a mixed fiber bulk 55 is produced.

The fiber bed 55 now reaches a first carding machine 56, where the fibers 15, 15' are sorted and, above all, further mixed. The resulting pre-fleece 57 is fed to a further mixing process by a suction device 58 and is transported via a conveyor belt 59 to a vibration chute, which is referred to in technical jargon as a "vibrachute". There, the mixed fibers are introduced via a needle cloth 61 into a filling chute 62, in which the fibers 15, 15' are exposed to ultrasound, which leads to a defined compaction of the fibers 15, 15' inside the chute. The transport speed of the needle cloth 61 is intermittently controlled by light barriers, the heights of which are determined by the indicated marks 63, while the fiber mixture 64 is continuously conveyed via rollers 65 provided in the shaft floor onto a conveyor belt 66, where a fiber web 67 is produced. This is then fed to a second card 68, where a pre-orientation of the fibers takes place. Behind the card, card webs 69 are produced, which are laid on top of one another in several layers in a zigzag shape and drawn off transversely, i.e. perpendicular to the plane of the drawing in Fig. 7, whereby a fiber fleece 14 is produced, the appearance of which was previously described in detail in Fig. 3. A specially designed thermofusion channel 70 now follows. This comprises a continuous lower and a shorter upper screen belt 71, 72, which is continuously moved and measures the thickness of the fiber fleece 14. The nonwoven fabric 14 has, as already mentioned, a weight per unit area of approximately 15,000 g per m ² . Hot air 75 is now blown through the sieve belts 71, 72, which leads to the mutual wetting of the two types of fiber 15, 15' already described in connection with Fig. 3 and 4 due to a softening of the sheath.

material of the binding fibers 15. At the exit of the thermofusion channel 70, a cooling belt 73 is arranged, which is height-adjustable as shown by the arrows 74 and leads to a defined calibration of the voluminous nonwoven fabric 24 produced there with the calibrated nonwoven fabric height 26 shown in Fig. 4. This nonwoven fabric 24 can already be cut there into sections 76 of the desired dimension in accordance with later use in the previously mentioned form 30 indicated in Fig. 7. In the process of Fig. 7, a discontinuous processing of the nonwoven fabric 24 in the form 30 is provided.

As already described in connection with Fig. 5, such sections 76 of the nonwoven fabric 24 are placed on top of one another with upper and/or lower sections of corresponding fabric panels 20 of a woven or knitted fabric to form a fabric combination 22 and placed between the two mold halves 31, 32 with a sieve-shaped structure, which are then pressed against one another, as already described by the arrows 33 shown in Fig. 5. Then, as already shown in Fig. 5, the treatment with hot air 23 follows, which leads to the described fusions at the various contact points 27, 28, 29 in the fabric combination 22, which were previously discussed in Fig. 6. Then, as can be seen from Fig. 7, cooling air 25 is blown through the still closed mold 30, which leads to a solidification of the already described compounds 27, 28, 29 in the material combination 22 of Fig. 6.

This creates the upholstery molded part 10 shown at the end of the process in Fig. 7 with the individual relief 34 already described, which is determined by the shape of the two

{&ggr;

Mold halves 31, 32 have been embossed onto this product. The outline edges 42, where the two-sided covering materials 20 have been guided closely against one another, can then be trimmed, as can be seen from the last station in Fig. 7, for which punching knives 77 are most suitable, which cut off the edge waste 78. The upholstery molded part IG shown in Fig. 6 is then completed.

In the process, instead of the second card 68, an aerodynamic process can also be used to produce the fiber fleece 14, where the mixed fibers 15, 15' are laid on top of each other like roof tiles. However, a card is more suitable because the contact points 19 described in Fig. are better formed there.

The nonwoven fabric 14 has a raw fiber density of approx. 100 kg per m. In the finished molded part 10, the different relief contours naturally result in different fiber densities in places, which are noticeable in the corresponding soft and harder, supportive areas. The average molded part density is approx.

3
200 kg per m . As already mentioned, the relief design of the molded part shown in Fig. 1 and 2 can of course also be designed differently, whereby pressed together web-like or point-like stiffeners can take on decorative functions in addition to their functional functions for supporting the body. This can be varied depending on the use and functional purpose of the molded part. Such a molded part 10 can be used not only for seats and loungers, but also for other pieces of furniture or other applications. Support elements for the human

Bodies can be manufactured in an analogous manner.

In Fig. 8, an alternative method for the continuous production of the cushion moldings 10 according to the invention is explained in more detail, which can be connected in terms of device to the described thermofusion channel 70. The starting point is the special material combination 22 already described several times, which is produced in a web and is continuously fed into the profile molding channel 80 in Fig. 8.

The profile forming channel 80 comprises two conformally movable endless screen belts 81, 82, each of which is provided with a continuous set of upper and lower mold halves 31, 32. The screen belts are guided in such a way that the molds 31, 32, aligned in pairs, are pressed from opposite sides against the web 79 of the material combination, which is ensured by continuous pressure rollers 83. This is what takes place as was explained discontinuously with reference to Fig. 5. The pressure rollers 83 cause the two mold halves 31, 32 to be pressed together as described by the pressure arrows 33. In this area of the two sieve belts 81, 82, which are aligned in terms of shape, only two zones 84, 85 are provided in which hot air 23 and cooling air 25 are blown through the sieve belts 81, 82 and the mold halves 31, 32 by fans (not shown in detail). The processes that have been explained above in Figs. 5 and 6 and in the last pictures of the discontinuous process in Fig. 7 take place.

During the transport movement 86 of the two screen belts 81, 82 and their deflection via transport rollers 87, the two halves 31, 32 are automatically

The resulting relief-like profiled web 89 is lifted off. In the web 89, the products produced are still connected and are then separated from one another by a cyclically operating punching knife 88, which results in the isolation of the upholstery molded parts 10 as shown in Fig. 8.
