mattress

The invention relates to a mattress for reclining furniture with cross-slat suspension, which on at least a fraction their total length is subdivided into resilient elements running transversely to the longitudinal axis of the mattress, which are at least in the middle mattress area extend over at least half the width of the mattress, said Elements are provided with a coating at least on their vertical mutual contact surfaces and all Elements including the adjacent edge areas are surrounded by an air-permeable shell.

Today's people are in increased numbers due to their one-sided way of life caused by the division of labor Mass exposure to damage caused by tension and tension Cramping and, in the long run, leading to widespread deformations of the spine in particular can. In the efforts to compensate for this increasingly widespread damage plays, as well as medical Side recognized and emphasized, the correct relaxation during sleep and thus the training the bed an excellent role.

108826/1015

The research carried out by the furniture manufacturer in collaboration with the medical profession has so far led for the development of a reclining furniture frame, which largely meets the requirements and in particular is aimed entirely at the relaxation of the recumbent human body (see Swiss patent no. 388 561 of the patent holder). A disadvantage of this construction, however, is that it applies to commercially available mattresses is dependent and the use of these mattresses partially the positive effects of the furniture construction again destroys. The influence of the mattress on the position of the resting person is crucial because the body of the resting body lies directly on it and there is any tendency to harden, to wrinkle or to accumulate Moist air on or in the mattress must have a direct effect on the well-being of the sleeper.

The mentioned shortcomings are eliminated thanks to the present invention in that the rounded longitudinal edges of the elements together with the adjacent cover, form a number of ventilation ducts running transversely to the longitudinal axis of the mattress and the coefficient of friction of said coating is chosen so that adjacent elements are under the influence a varying load are mutually displaceable in the vertical direction, the center-to-center distance from one another adjacent elements corresponds to the mutual spacing of adjacent transverse slats of the furniture.

In a preferred embodiment, said resilient elements extend over the entire mattress surface with the exception of an all-round peripheral area. Each resilient element is preferably with one Provided cover, which expediently consists of a hygroscopic material, for example a woolen material.

An example is shown in the accompanying drawing of the subject matter illustrated. _ 3 _

Fig. 1 shows the partially cut mattress in perspective representation on the transverse slats of a piece of furniture,

2 and 3 are partial longitudinal sections of the mattress and Figure 4 is a simplified plan view of the mattress.

Fig. 1 shows, neglecting insignificant details, a slatted frame 1 of a piece of furniture, which is made up of in mutual There is spaced-apart crossbars 2. The j, designated in its entirety by 3, rests on these crossbars Mattress. ■

In the selected embodiment, the mattress 3 has a foam mattress core 4, which while maintaining a completely circumferential edge portion 5 (Fig. 4) by parallel cuts in individual, resilient Elements 6 is divided. Each individual resilient element 6 thus depends on its two end faces 7 (FIG. 4) with the; Edge section 5 together, is abBr in relation to the adjoining:

the neighboring elements in the vertical direction, so that the individual elements 6 depending on the local Let the load press down to various degrees and thus, in cooperation with the slatted frame 1, a differentiated cushioning that always adapts to the body position of the sleeper.

This adaptability of the! Mattress in that the center-to-center distance of neighboring elements 6 corresponds exactly to the mutual spacing of the crossbars 2, in such a way that on each crossbar 2 a resilient one Element 6 comes to rest. ;

The possibility of mutual displacement of contiguous Elements 6 would be in the described arrangement '

but still relatively small, if not one more

109826/1015

Feature would be added. In order to reduce the friction on the surfaces of mutual contact of the elements 6, are all elements 6 provided with a coating 8, which the parallel-epiped-shaped elements in the present Embodiment surrounds on all four sides. By choosing an appropriate coating material, you can achieve a coefficient of friction that allows the elements 6 to be displaced as desired and thus the optimum adaptability guaranteed by the mattress.

As FIGS. 1 to 3 show, all elements 6 are surrounded by an air-permeable envelope 10. In cooperation with the rounded longitudinal edges of the elements 6, the shell 10 forms the designated in Fig. 2 and 3 with 11, transversely to Ventilation channels running along the longitudinal axis of the mattress. By the movements of the person resting on the mattress are displaced against each other, the elements 6 being within the ventilation ducts 11 a pumping effect occurs, through which the moist air contained in the ducts from time to time Time is expelled and fresh air is drawn in from outside.

This constant ventilation, which occurs depending on the movements of the person at rest, differs from the described mattress of all known designs, which consistently have the lack of insufficient ventilation. The zones of cold, humid air that form in these well-known mattresses lead to the formation of condensation in the border zones, what in view of the associated odor formation and accumulation of bacteria from a hygienic point of view out is very undesirable.

Since experience has shown that a resting or sleeping person moves again and again at certain time intervals, the described new mattress for a constant discharge of the humid air. This is also supported by the Choice of the material of the sheath 10, which preferably consists of a

109826/1015

a moisture-transporting fabric, e.g. a woolen material or a cellulose material. As a result, the shell exercises itself a wicking effect, so to speak, in that the moisture within the mattress is automatically drier Outside derives.

When choosing the covering material for the elements 6, it is important to that the occurring coefficient of friction, the mutual displacement of adjacent elements only from one May allow certain loads, the occurring displacement paths, although relatively small, but for the comfort of lying are of vital importance. Of the two elements loaded according to FIG. 2, the one on the left already has something shifted downwards, while the right element was only elastically deformed in itself. Is of particular importance here of course, that an element 6 comes to rest on a corresponding crossbar 2 of the furniture, so that the border areas of adjacent elements each lie above the spaces between two crossbars 2.

The mattress described can undoubtedly not only be placed on cross-slatted frames, but in conjunction with all others Use spring support systems. However, its optimal effect is on transverse slatted frames, especially in accordance with Swiss Patent No. 388 561.

In the known mattresses takes place due to a shift of the resting person, there is also a slight shift in the moist air contained in the mattress. In doing so, however, the air is displaced from one mattress section into the adjacent mattress sections, which is the case with the described Mattress construction thanks to the mutual separation of the elements 6 is impossible.

The mattress described thus ensures an excellent, Ventilation in transverse direction controlled by the constant movements of the sleeper.

109828/1015

Thanks to the individual resilience of the individually mounted elements 6, the effect of the cross-lath sprung base comes about only really comes into its own. The formation of hardening within the mattress and wrinkles on the mattress surface is avoided so that the sleeper's body is always properly supported.

The mattress core 4 (Fig. 1) can be made of a foam, as well as any other mattress filler, for example horsehair, rubber, etc. exist. A hygroscopic textile material is preferably used for the covers 8, For example, a woolen fabric or natural silk was chosen. The use of other coating materials, e.g. plastics, Cotton, rayon, etc. is quite possible and may, depending on the desired sliding effect, even be more beneficial. Bring organic fibers such as wool and silk, as well as other hygroscopic textile materials with the advantage that they absorb the moisture evaporated by the sleeper first and then, thanks the described pumping action, can release again.

The individual elements 6 could differ from that shown Embodiment can also be completely separated from one another. In these cases the parting lines would be between adjoining elements 6 thus continuously and the cohesive effect of the edge portion 5 could affect others Art, for example, by sewn straps, replaced.

Depending on requirements, elements 6 made of materials of different hardness or hardness can also be installed at certain points on the mattress. Use elasticity so that individual parts of the body, e.g. certain parts of the spine, are specifically supported can.

According to FIG. 3, a foam core can be used with advantage which has a stiffening central strip 9.

By using this known foam combination, a graduated spring effect is achieved in which smaller loads are only absorbed by the upper part of the mattress core and sagging of the lower foam section only occurs above a certain minimum load.

To achieve the desired mutual displaceability of the elements 6, it would of course not be necessary to provide them entirely with a coating 8. It would too The textile or film material selected to reduce friction is sufficient only at the lateral interfaces of the Elements 6 to attach.
