Abstract

(57) [Summary] [PROBLEMS] To provide a mattress having different load compressibility according to the body shape of an individual according to the preference of the user. SOLUTION: A three-dimensional fibrous structure composed of two ground structures and a connecting portion connecting the ground structures is used as an upper layer, and a layer made of a polyurethane foam having an uneven upper surface is polymerized as a lower layer. A mattress consisting of a cotton layer on at least the upper surface and covering them with a dress material and lining.

Description

[Detailed description of the invention] [Industrial applications]

The present invention relates to a mattress, and more particularly to a mattress adapted to a user's body.

[Prior art]

There are various designs of mattresses and mattresses for obtaining the best sleeping comfort. For example, mattresses made of polyurethane foam having irregularities to support the body by points, not surfaces, soft layers, hard layers and springs. A mattress having a triple structure consisting of a cushion layer has been proposed.

[Problems to be solved by the invention]

[0003] Although various proposals have been made in this way, people who use mattresses and mattresses have preferences, and because of their different heights and weights, there are few things that can be satisfied for the individual. Focusing on this point, this inventor devised a mattress with different load compressibility according to the individual's body type.

[Means for Solving the Problems]

[0004] This invention proposes a layer made of a polyurethane foam having a three-dimensional ground structure and a connecting portion for connecting the ground structure, a fiber structure having a cubic structure as an upper layer, and an uneven upper surface. The above purpose is achieved by a mattress having a structure in which the lower layer is polymerized, and a cotton layer is disposed on at least the upper surface thereof, and the layers are covered with a surface material and a lining. It is divided into three parts, for example, head, shoulder, waist, and legs. By changing the load compressibility of each part, it is intended to obtain a mattress suitable for each individual.

【Example】

FIG. 1 is a cross-sectional view showing the structure of the mattress of the present invention. Reference numeral 1 denotes a three-dimensional fiber structure composed of two front and back ground tissues and a connecting portion connecting the ground tissues. The material can be appropriately selected, and for example, polyester fibers such as polyethylene terephthalate and polybutylene terephthalate are used. (Structure of Patent No. 212 5634)

[0006] The three-dimensional structure of the fibrous structure 1 is superposed as an upper layer, and a layer 2 made of polyurethane foam having a concave-convex upper surface is polymerized as a lower layer under the upper layer. In the example, a cotton layer 3 (wool cotton, polyester cotton) is overlaid on the upper surface and the lower surface, and 4 and 5 cover the whole with a surface material and a lining. The fibrous structure 1 may be one, and the number is not limited.

A feature of this invention is that the layer 2 made of polyurethane foam is divided into a plurality of, for example, three parts as shown in FIG. 2, that is, a head shoulder 2A, a waist 2B, and a leg 2C. By doing so, the load compressibility of each part can be changed.

[0008] That is, when sleeping in a normal state, a load of about 35% is applied to the head and shoulders 2A, about 45% to the waist, and about 20% to the legs, but depending on the weight and height of the individual, the load is reduced. There is also a difference in the distribution, and in order to respond to this, the hardness of the layer made of polyurethane foam is determined by changing the shape of the unevenness and the density of the material.

【effect】

In the present invention, the cotton layer on the upper surface is in soft contact with the body, the three-dimensional fiber structure diffuses the load, and the layer made of the uneven polyurethane foam absorbs the load. Since the polyurethane foam layer is divided into a plurality of parts, it is possible to adjust the hardness of each part to the preference of each individual, and it is possible to obtain a special mattress suitable for each body type. .
