Field of the Invention The present invention can maintain a sleeping posture closer to a state of lying on a floor, obtain a sleeping posture which is said to be physiologically desirable, and provide a good sleeping comfort. The present invention relates to a bed mat that can be provided by industrial production and a mat for bedding suitable for a mattress or the like.

報にその発明が紹介されている。However, cotton, wool, and polyester cotton, which are widely used, have a problem in that the thickness immediately decreases, and the cotton is made felt and sagging. In addition, cotton and wool cotton are natural products, which may cause mold growth depending on the mite breeding and storage conditions, etc. Is required. In addition, urethane foam is one of the most excellent materials from the point of sagging, but urethane foam has no breathability, so during sweating, when sweating increases, especially in summer etc. It is hard to say that it is appropriate. In recent years, Japanese Patent Application Laid-Open No. 7-58061 has introduced the invention as a material having less settling and excellent air permeability.

Waterbeds and various types of bedding mats that suggest good quality have been proposed and are commercially available.

言われているのである。[0005] The present inventors have studied the comfort related to the use of mats for bedding in general, and found that bedding that is considered physiologically good for the human body includes not only body pressure dispersibility but also sleeping pressure. Attitude has been found to be a very important factor. That is, the desirable posture when sleeping is a form in which the posture when a person lays on the floor is reproduced even when using the bedding, and the gap between the waist, that is, the waist and the buttocks and the back is the surface of the cushion body. Although the entire body sinks to the extent that it touches the buttocks and back, it is said that the configuration of the cushion body, which does not sink too much, can keep the sleeping posture closer to the state when lying on the floor, which is physiologically desirable It is.

いても、従来特定することが難しかった。However, in the current various bedding mats, materials which can maintain the sleeping posture in a physiologically favorable state as described above and what is good as a cushion body are not yet described. I can't find the proposal. This seems to be a major reason that there has been no general method of measuring the sleeping posture for a long time. The only conventionally proposed measuring method of the sleeping posture is to stretch the treatment bandage to which gypsum is attached in advance thinly on bedding and then moisten it, and then lay the subject on it until the gypsum hardens, A method called gypsum molding is used to take out the shape. However, this method is a measurement method that is extremely burdensome both physiologically and psychologically because the subject needs to be stationary on the gypsum bandage to be hardened until the gypsum hardens. In addition, for the analysis, it is necessary to perform an image analysis on the assumption that the gypsum mold solidified into a human figure is a contour line, and this is a measurement method that requires considerable labor. In the current situation where it is extremely difficult to measure the sleeping posture, research on the sleeping posture has not naturally progressed, and therefore, in order to obtain a desirable sleeping posture, what is good as a cushion body,
In addition, it has been conventionally difficult to specify what kind of compression characteristics are required.

としては大いに無理があるのが現状である。[0007] On the other hand, although there are few research examples focusing on the direct sleeping posture, recently, as a measure to improve the sleeping comfort when lying on the cushion body, in recent years, for each contact part of the human body, for example, for each part such as the waist, buttocks, and back, A method of examining changing the hardness of the cushion body has been proposed. However, according to this method, it is necessary for an expert to carefully examine the hardness of the cushion body for each contact portion of the human body for each individual. Therefore, even if it is possible to specify the hardness distribution for each part of the human body as a cushion body that can be said to be a desirable sleeping posture, in actual practice the body shape such as height and weight varies from individual to individual, so production and At present, there is no reasonable means of designing a cushioning body that can be sold and tailored to the individual, and that matches the idea of the previous term, and provides it to the market.

Invented the mat. That is, a bedding mat having a thickness of at least 40 mm in which a cushion portion is wrapped around a side fabric made of a woven or knitted fabric, wherein the cushion portion has a structure in which two layers of cushion bodies are laminated, and has a diameter of 1 mm.
When compressive strain is applied using a 50 mm circular pressure plate, the compressive stress at a compressive deformation of 20 mm is 10 to 40 gf / cm 2 , and the compressive stress at a compressive deformation of 40 mm is 160 to 22.
A mat for bedding characterized by having a weight of 0 gf / cm 2 . Further, the thickness of the layer on the human body side of the two-layer cushion body is 10 to 40 mm, and when a compressive strain is given using a circular pressure plate having a diameter of 150 mm, the compressive stress when the amount of compressive deformation is 10 mm is 1 to 40 mm. 14 gf / cm 2 , the thickness of the other layer is 20 mm or more, and when a compressive strain is given using a circular pressing plate having a diameter of 150 mm, the compressive stress when the amount of compressive deformation is 10 mm is 70 to 155 gf / cm 2. The mat for bedding according to the above, and a part of the cushion body, forms a random loop by winding continuous filaments made of a thermoplastic elastic resin and having a wire diameter of 5 mm or less. The mat for a bedding as described above, characterized in that most of the contact portions of the respective loops are formed of a three-dimensional three-dimensional structural mesh body having a thickness of 10 mm or more which is fused to each other.

It consists of. The compression characteristics are
It is measured on the entire mat including the side of the woven or knitted fabric.
The hard layer is evaluated by the compressive stress at the time of (1). The compressive stress when the deformation amount 20mm With 10~40gf / cm 2, is contacted with the waist to the mat surface, is less than 10 gf / cm 2,
If it is too soft, a feeling of contact with the mat surface of the waist cannot be obtained, and if it exceeds 40 gf / cm 2 , the mat surface is too hard and the amount of sinking is insufficient, so that the mat surface does not contact the waist. Preferably 15 to

Compressive stress is 1 to 1 when compressive deformation is 10 mm
It is 4 gf / cm 2 . When the thickness is less than 10 mm, the waist does not come into contact with the mat surface, and when the thickness exceeds 40 mm, the total sinking amount becomes large, and particularly, the buttocks become too deep and the sleeping posture becomes V-shaped, which is not preferable. The compressive stress when the amount of compressive deformation 10mm in less than 1 gf / cm 2, can not be obtained contact feeling to the mat surface of the waist too soft, and if exceeding 14 gf / cm 2, the amount of sinking too hard is The mat surface does not contact the waist due to lack. On the other hand, the hard layer on the anti-human body side has a thickness of 20 mm or more and a compressive stress of 70 to 155 when the amount of compressive deformation is 10 mm.
gf / cm 2 is preferred. If the thickness is less than 20mm,
