Abstract

The furniture upholstery material takes the form of a cushion with a number of pressure spring elements. Each element (2) is arranged spatially and structured and held together by holding devices. The spring elements (2) consist of a web (6) of yarns made through intermeshing and combined several times to produce the spatial element. The yarn is a loose textile yarn twisted out of sub-yarns.

Description

The invention relates to furniture upholstery in which a variety is formed from compression spring elements in pillow format and one wide-area composite is put together in the each compression spring element is a spatially structured structured Element is and is held together by holding means and at the web material in every cushion format compression spring element Thread made by stitching and to the spatial element is often merged.

A known (US-PS 4,324,012) furniture upholstery of this type is a flat cushion layer, which is placed on an automobile seat and is placed on a seat back. The thread of the web material this Furniture upholstery is relatively stiff and works due to bending feathery. The thread is made of plastic and is neither elastic, still jumping back. So this is a monofilament Thread. The flat upholstery layer for an automobile seat is supposed to do more have the function of a shock-absorbing layer. The well-known furniture upholstery thus results in a relatively hard elasticity. At a Furniture upholstery is usually a soft, long-lasting one Elasticity wanted.

Furniture upholstery is also known (DE-PS 39 09 716) from a single mattress format compression spring element with a wide, flat surface Extent exists. Here is layer thick Web material made from crimped staple fibers, distributed indiscriminately are manufactured and multiple to the mattress format furniture upholstery merged. This furniture upholstery is without special coverings soft, resilient and heat-insulating. Because this furniture upholstery not in individual cushion format or package-like compression spring elements is subdivided, it shows the resulting special Upholstery properties not. Because the crimped staple are randomly distributed, this furniture upholstery can have their upholstery properties, e.g. Suspension properties from one area to the next Change area.

Vibration technology is one to be used as a vibration damper Pillow format compression spring element known (DE-OS 38 15 750), in the web material made from thread by stitching and often to a spatially structured structured element is merged. The thread is a monofilament flexible Steel wire. The one obtained by collapsing the sheet material spatial element is compressed so much by pressing, that there is permanent deformation of the spring wire. This pillow sized or packet-like compression spring element is for furniture upholstery not suitable because it is too heavy, insufficient suspension properties owns and, in terms of use by people who is too hard.

An object of the invention is therefore to upholster the furniture to create the kind mentioned above with regard to additional rubbers can be simplified and in terms of softness and Thermal insulation is improved. The furniture upholstery according to the invention is solving this problem, characterized in that the thread is a loose textile thread twisted from partial threads and that the threads are spun from fibers.

The furniture upholstery according to the invention requires softness-promoting and not thermal insulation coverings insofar as the individual cushion-shaped or package-like compression spring elements from one soft material and a large number of distributed have very small empty voids, i.e. insulating are. Due to the meshing or stitch formation, the knitting, Knitting or crocheting is a predictable structuring given each compression spring element. Because of the merging the compression spring element is structured. The desired ones Upholstery properties, especially the desired suspension, result themselves due to the use of the textile thread in the from partial threads or individual threads twisted form. The twist brings a certain elastic stretchability of the textile thread with itself. The upholstery and Suspension properties are very durable. The compression spring element can be precisely predetermined due to the meshed web material produce and have the due to the textile material Softness and without compacting the necessary suspension properties on. Since the part threads are spun from fibers, So it is not extruded threads. The fiber structure of the partial threads improves their permanent elasticity.

The web material is e.g. knitted or knitted. It is particularly expedient and advantageous if the meshing of the web material is a crochet mesh. That kind of Meshing results in a web material that has elasticity or suspension properties is improved.

The textile thread is e.g. from only two threads or thin Threads. It is particularly expedient and advantageous if the textile thread is twisted from more than two threads. This improves the permanent elasticity of the furniture upholstery.

It is then particularly expedient and advantageous if the textile thread consists of animal wool or an equivalent plastic wool. Cotton is excluded here. Amazingly the compression spring element of the furniture upholstery according to the invention animal wool, e.g. Sheep's wool, with the desired Establish compression spring properties. There is furniture upholstery made of natural material.

The furniture upholstery is primarily a mattress for reclining furniture, but also the seat cushion or back cushion of a piece of seating furniture. The Furniture upholstery is geared towards human use Upholstery. The web material is sufficiently tight meshed that the desired upholstery properties even without Compacting are given. However, a bias is the Compression spring elements conceivable. The compression spring elements of the furniture upholstery are arranged more or less close to each other. The compression spring properties of the compression spring elements can be improve the textile thread in one of its spring properties is treated in an improving manner.

The holding means have the function, the respective compression spring element hold together and are e.g. by the length of the Retaining threads passing through the compression spring element. Usually are the holding means are designed as a guide frame, which e.g. a cloth bag and the compression spring element against deforming pressure holds together and thus improves the compression spring properties. The compression spring element has a load surface to which the compression force is rectangular. With the cushion format of the compression spring element usually makes at least the height of the compression spring element a quarter of the smaller dimension of the load area. The Compression is usually perpendicular to the compression spring element forming layers.

However, it is also particularly expedient and advantageous if Front edges of the often folded web material one Form the load area for a compressive force. For example from the web material a tightly wound roll wound in the axial direction is charged. A large number of such rollers become axially parallel arranged side by side and the top faces of the rollers form the load area.

The narrowest possible web material is e.g. of flat mesh frames formed, i.e. essentially two-dimensional. Especially However, it is expedient and advantageous if the meshed Track material forms densely arranged ball structures, each from several intertwined thread courses consist. These ball structures improve the compression spring properties of the compression spring element considerably. It's a mesh Web material of increased thickness, i.e. in three-dimensional design in front. The ball structures can be crocheted by the Generate web material. Every thread is a more or less curved circumferential thread section. The ball structures are e.g. arranged close together, each ball formation two or more touches adjacent ball structures.

It is particularly useful and advantageous if each Ball structures more than two thread courses are present. Since it is the Bend of the thread passages, which increases the cushioning properties, a larger number of thread courses is an advantage.

The web material is e.g. divided into individual pieces that are stacked on top of each other are. It is also possible to have a stripe-like Rolling up web material or winding it into a roll. Especially However, it is expedient and advantageous if in the spatial Element of adjacent layers of the web material over Fold the web material into one another. These tight 180 ° bends or folds improve the spring properties of the compression spring element quite significantly.

It is also particularly expedient and advantageous if at least some of the cushion format compression spring elements are out of round in cross section are. In this way, the compression spring elements can be determined Adjust contours of furniture upholstery.
