In the bedding of the present invention, since the surface of the bedding main body is formed in an uneven shape corresponding to the skeletal structure along the trunk direction, the sinking amount is small in the concave portion and the sinking amount is large in the convex portion. .

[0007] Therefore, the body can be supported over the entire surface of the bedding body, and the pressure receiving area can be increased to suppress the concentration of stress, so that, for example, bed sores of bedridden patients can be prevented. Further, when lying on the bedding of the present invention, the body becomes straight as in the standing state, so that the sleeping comfort is remarkably improved even for patients other than bedridden patients.

[0008] (2) In the bedding of the present invention, the specific shape of the surface of the bedding body is made uneven according to the skeletal structure.
Although not particularly limited, it is preferable to provide the surface of the region corresponding to the sacral portion (M2) in the lying state at a lower position (recess 111) than the peripheral region.

If the surface of the sacral area in the lying state is lowered, the amount of sinking of the sacral part becomes large, so that the standing posture can be maintained as it is, and at the same time, the pressure receiving area becomes large despite the large weight acting. Pressure concentration can be suppressed.

Further, in the present invention, it is preferable that the surface of the region corresponding to the lumbar vertebra (M1) in the recumbent state is formed to protrude from the peripheral region.

When the corresponding region of the lumbar vertebra in the lying state is raised and formed (raised portion 112), the amount of sinking of the lumbar vertebra becomes small. It can be supported over the entire area of the bedding body.

Further, in the present invention, it is preferable that the surface of the region corresponding to the thigh (M4) in the recumbent state is formed so as to protrude with respect to the peripheral region (raised portion 113).

When the surface of the corresponding region of the thigh in the lying state is formed by raising the surface, the amount of sinking of the thigh is reduced. It can be supported in the whole area, and stress concentration can be suppressed.

In the present invention, the heel portion (M
3) Position the surface of the corresponding area at a position lower than the peripheral area (recess 1).
It is preferable to provide it in 14).

In the recumbent state, the heel also bears weight. Therefore, by setting the heel lower, the sinking amount can be increased, the standing posture can be maintained, and the pressure receiving area can be increased to suppress the pressure concentration.

Further, in the present invention, the surface of the bedding body may be formed in an uneven shape corresponding to the skeletal structure along the body width direction (X).

(3) The bedding of the present invention can be used only with the bedding body (11), but if necessary, a flexible pad (12) can be provided on the surface of the bedding body.

By providing the flexible pad on the surface of the bedding body having the uneven shape, the pressure receiving area increases in the body width direction, so that the stress concentration is further suppressed. In addition, since the flexible pad is provided, it is possible to easily turn over, and in that sense, the sleeping comfort is improved. In this case, if the surface of the flexible pad is formed flat, the appearance and the storability are improved.

As shown in FIG. 1, the bedding 1 of this embodiment
Is provided with a bedding body 11 having substantially the same plane in the body width direction X and having an uneven shape along the trunk direction Y. In the present embodiment, the bedding main body 11 having substantially the same shape in the body width direction X is illustrated.
May have an uneven shape corresponding to the skeletal structure also in the body width direction X.

The material constituting the bedding body 11 is not particularly limited, and can be made of hard urethane, wood, bamboo board, various synthetic resins, or the like.

A specific example of the surface shape of the bedding body 11 will be described in the lying state shown in FIG. 2. First, in the present embodiment, the area corresponding to the sacral part M2 in which the skeleton structure of the body M is convex downward in the lying state. Has a concave shape (recess 111), and its surface is provided at a low position. This is because, in the recumbent state, the sacrum M2 has the largest weight and has a large body pressure peak value. Therefore, by providing the recess 111 in the sacrum M2, it is possible to avoid supporting the sacrum M2. It suppresses concentration.

On the other hand, on the surface of a region corresponding to the lumbar vertebra M1 in which the skeleton structure of the body M is convex upward in the lying state, a bulge 112 along the curved shape of a lumbar vertebra of a general body type is provided. And supports the lumbar spine M1 across this series of ridges 112.

Similarly, on the surface of a region corresponding to the thigh M4 from the sacrum M2 toward the toe, a protruding portion 113 is formed along the curved shape of the thigh having a general body shape. The thigh M4 is supported over the entire area of the raised portion 113.

Further, if the heel M3 is to be maintained in the lying-up state, the heel M3 is also located on the lower side. Therefore, the surface of the area corresponding to the heel M3 is provided at a position lower than the surrounding area (recess 114). .

The head M5, which is another area, is also
The height is such that the standing posture can be maintained in the lying state.

Although not shown, a cover may be provided to cover the entire bedding body 11 when used. Further, the hardness of each part of the bedding body 11 can be made different.

Next, the operation will be described. It can be said that the bedding which can be laid in the same posture as the upright posture is good for bed sores and a comfortable bed. However, when the human M lays on general bedding, the sacral part M2 and the heel of the hips projecting to the lowermost side. M
No. 3 is going to sink most, and conversely, a gap is going to be created in the lumbar vertebra M1 and the thigh M4 projecting to the uppermost side.

However, in the bedding 1 of this embodiment, the sacral part M2 and the heel part M3
Are formed as the concave portions 111 and 114, and the surfaces of the regions corresponding to the lumbar vertebra M1 and the thigh M4 which are curved to the uppermost are formed as the raised portions 112 and 113.
In the lying state, the same posture as the upright posture can be maintained. In particular, by providing the concave portion 111 in the sacral portion M2, it is possible to avoid supporting the concave portion 111, thereby suppressing stress concentration due to pinpoint.

Therefore, according to the bedding 1 of the present embodiment, it is possible to lie down in a posture very close to the upright posture, thereby improving the sleeping comfort and contributing to prevention of bedsore and correction of the posture. Also, if a material having a specific gravity of 1 or less is used, weight reduction can be achieved as compared to a water mat,
It is convenient for transportation.

The embodiments described above are described for the purpose of facilitating the understanding of the present invention, and are not described for limiting the present invention. Therefore, each element disclosed in the above embodiment is intended to include all design changes and equivalents belonging to the technical scope of the present invention.
