TH22249B - "Multi-layer support with different areas of firmness" - Google Patents

Abstract

Cushions that are stacked together, including Layers of material with different densities where free space is Made to Overhang at least a certain cross-section of at least The two adjacent layers are used to form the cushion area. With different support properties determined by the placement and extent of that space in nested layers. Nesting of Layer with dense material on top of the layer containing A material with a relatively low density produces a cushion that is relatively dense, with varying degrees of variation. Of the density and the boundary of space, vice versa. Overlapping layers of low-density material on top of a layer of relatively dense material The high side produces a relatively soft cushion, as well, depending on the arrangement of the degree of firmness change Place and boundary of space This cushion can be cut to provide Fits the figure with the size of the normal mattress And the area being made in the area of the cushion that meets the requirements of Support weight for maximum support of the human body in a flat mattress position.

Claims (1)

1. A cushion that contains a large number of areas where you can accommodate one area is different from The support features of other areas include: First layer with first density The second layer is stacked next to the first layer and will be thicker. The second tightness differs from the first density and the bulk clearance is made so that it passes at a minimum. Partial cross-section of the first layer And the second floor where the number of placement or the extent of the free space determines the area of the cushion
