ORTHOPAEDIC BEDDING AND ITS MANUFACTURING METHOD Russian patent published in 2009 - IPC A47G9/00 A61G7/07 A61F5/37 

FIELD: household goods and personal effects; medicine.

SUBSTANCE: orthopaedic bedding contains covering with filling compound. The covering is made from water-repellent breathing cloth. The filling compound is made in the shape of microballoons - hollow particles of spherical shape, from 15 microns to 3 millimeters in diametre, with heat conduction coefficient being equal to 0.07 W/micron. Cloth cell width does not exceed the microballoon size. Orthopaedic bedding manufacturing method stipulates for production of covering and stuffing it with filling compound. The two identical parts of the covering are shaped from water-repellent breathing cloth, according to the dimensions given. Then, a transfer is shaped, strictly following the dimensions. After that, the two parts of the covering are coupled by gluing them to the transfer at three sides, at the distance of 8-9 mm from the edge of cloth. Fourth side is kept apart by protective paper. Then, an oblique border of cloth is cut. The length of it must be equal to the covering perimeter. Afterwards, the border is glued using stretch mesh. Then, at the edge of glued covering the stretch mesh is put. The oblique border and stretch mesh are tacked and stitched from three sides. After that, the three sides of the covering are ironed to melt the stretch mesh. The prepared covering is stuffed with filling compound according to the weight specifications. The protective paper is removed from the fourth side of the covering, which is immediately glued with transfer. Afterwards, cloth, oblique border and stretch mesh are tacked and seamed. The fourth side is ironed.

EFFECT: maximal comfort for user due to effect of heat accumulation and its uniform distribution, as well as uniform distribution of load, increase of space factor.
