Description

F ί g, 3 shows that a support 13 in the form of a support tube is used on such a channel 6 is, which has openings 8, between which webs 9 are arranged. Connect the bridges Rings 14 (Fig. 5).

During the deformation (F i g, 4) the support 13 is compressed in the same way as the the rest of the mattress, which supports the ventilation effect,

F i g. 5 shows that in the envelope 10 by means of the ic Ntilue 11 an insert 12 is used for air circulation to obstruct by wrapping 10 ntcüt.

The supports 13 can be arranged in the channels 6 in such a way that the channels initially are recessed or drilled out and that the supports 13 are then used. However, it is also possible to press the supports into the solid material, which naturally results in a somewhat stiffer product is obtained.

The main reason for this should then consist essentially of the deformability of the cushion, that the pores of the foam correspond to in, so that the channels with the supports are able to absorb moisture, but that there is no change in the elastic properties of the material, that forms the pores, does not itself or mattress and is therefore not only slightly absorbent from the outside.
