決が見られていない。2. Description of the Related Art Prevention of pressure sores (bedsores) often occurs in persons who have been on the floor for a relatively long period of time, such as inpatients and bedridden elderly people. Has been a long-held wish. For the purpose of preventing pressure ulcers, futons, mattresses and sheets have been improved, and cushions have been inserted between the body and the floor, but no satisfactory solution has yet been found.

ものである。[0003] The pressure ulcer is caused by the fact that the contact point between the body and the floor hardly changes, and the contact part is pressed to deteriorate blood circulation. In addition, poor air permeability between the body and the floor accumulates heat from the body, causing not only the discomfort of being hot and stuffy, but also the occurrence and promotion of pressure sores. Therefore, sandwiching the cushion between the body and the floor is preferable from the viewpoint of preventing pressure on the contact portion from the body pressure dispersibility of the cushion, but a cushion material such as urethane is inferior in air permeability. There are drawbacks. Further, although cushion materials such as urethane are soft and flexible, if they are pressed by body pressure, body pressure dispersibility will be reduced. On the other hand, a pillow-shaped cushion material in which buckwheat hulls and pipe materials are put in a bag has a problem that it has a high air permeability but lacks a body pressure dispersing effect. Furthermore, from the viewpoint of hygiene, it is also required to have good washability and dryness, such as easy washing and quick drying.

タック組織で引っ掛けられたものであってもよい。The connecting yarn 31 extends from at least 30% of the stitches of the mesh-shaped knitted fabric 1 toward the other knitted fabric 2. The connecting yarn 31 is interposed between the front and back knitted fabrics 1 and 2 to form a space between the knitted fabrics 1 and 2, and the connecting yarn 31 is elastically deformed to form a knitted fabric. The contraction is performed by reducing the interval between the first and second parts. Here, the elasticity is such an elasticity that it can be deformed by a human load and can return to its original shape when the load is removed. Then, in order to maintain appropriate elasticity, the connecting yarn 31 needs at least 30% of the stitches of the mesh-shaped knitted fabrics 1 and 2. When the number of the connecting yarns 31 is less than 30% of the number of stitches of the knitted fabrics 1 and 2,
There is a possibility that sufficient elasticity may not be maintained. In order to obtain a relatively hard cushion, more connecting yarns 31 are required, so that at least one connecting yarn 31 is provided from each stitch, and the number of connecting yarns 31 is equal to or less than the number of stitches. It is also desirable to use a larger number. As described above, when the connection yarns 31 are relatively densely arranged, it is desirable to use a monofilament as the connection yarn 31. The connecting yarn 31 may form a loop-shaped stitch in the front and back two-layer knitted fabrics 1 and 2, or may be hooked on the front and back two-layer stitch with a tack structure.

Further, as shown in FIG. 3C, the shape may be irregular. Further, at least two types of the straight connecting yarn 31, the connecting yarn 31 curved in an arc shape, and the connecting yarn 31 curved in an irregular shape may be combined. When curved in a bow shape, it is desirable that at least half of the plurality of connecting yarns 31 connecting the front and back knitted fabrics 1 and 2 bend in a substantially constant direction. For example, in the example of FIG.
The connecting yarn 31 extends substantially vertically between the front and back knitted fabrics 1 and 2, and the connecting yarns 31 are aligned in the same direction and are curved in an arc shape. When the force f is applied, the connecting yarns 31 are uniformly curved to increase the degree of curvature in an arcuate manner, and the space between the front and back knitted fabrics 1 and 2 contracts smoothly. In the example of FIG. 3B, the connecting yarns 31 are arranged in an inclined manner, and the connecting yarns 31 are curved in the same direction in an arc shape. Force f
Is added, the connecting yarn 31 increases the angle of inclination in the direction in which the connecting yarn 31 is inclined, and the connecting yarn 31 is curved so as to increase the degree of curvature in an arcuate manner. The space shrinks more smoothly. The connecting yarns 31 in each of the three-dimensional knitted fabrics 3 may be all curved in a certain direction and may be curved in an arc shape. Between the knitted fabrics 1 and 2 shrinks smoothly. In this way, when at least 50% of the connecting yarns 31 are curved in a certain direction in an arcuate manner, when shrinking, the front or back knitted fabrics 1 and 2 are slid so as to slide in a certain direction. I do.
In this way, by contracting with directionality, the knitted fabrics 1 and 2 can be contracted smoothly without applying excessive force.
