[0002]

2. Description of the Related Art In general, a bed is composed of a bed frame and a mattress as bedding placed on the bed frame, and the performance of this bed depends on the body shape of the person using the mattress. It depends greatly on whether or not it exists.

[0003] That is, when the user is lying on the mattress, the waist is moved to the tangent of the back of the chest and buttocks by a few points.
Constant height of cm (about half of standing) (recessed state)
It is said that it is comfortable when you sleep so that it fits in.

[0004] On the other hand, if the chest and buttocks fall extremely into the mattress and the waist is relatively pushed up, the user feels pain and cannot sleep well. Therefore, a hard mattress is preferable in order to reduce the depression between the chest and the buttocks.

[0005] However, if the mattress is too hard, the depression between the chest and the buttocks is small, but the body is supported only by these parts, so that pressure is concentrated on the chest and the buttocks, and it is also not comfortable to sleep. Will be.

[0006] By the way, in order to select a mattress that is comfortable to sleep, even if a mattress is simply selected based on a judgment such as a hard mattress or a soft mattress, depending on conditions such as the physique and weight of a person using the mattress, the chest and buttocks are not determined. The amount of dip differs. Therefore, the quality of a mattress is determined not only by whether the mattress is hard or soft, but also by whether the hardness of the mattress is suitable for the physique and weight of the person using the mattress. It is necessary to select a mattress suitable for the user.

[0007] Accordingly, the present applicant has filed Japanese Patent No.
No. 4 proposed a mattress selection device. The device of this patent has a measurement mattress on which the person to be measured (user) lies.

By displaying the state on the display unit together with the state, a mattress having a hardness suitable for the subject can be selected from these displays.

However, according to such a device,
In order to measure the pressure distribution according to the body shape of the person to be measured, the person to be measured must lie on the mattress for measurement, and the measurement may be troublesome. The pressure distribution when lying on the upper surface tends to cause an error depending on the position of the person to be measured on the measurement mattress, and thus it is difficult to accurately measure the pressure distribution.

The processing device 51 converts the detection signal from the sample rod 12 into a processing unit 52.
To obtain the back shape of the subject M, display the shape A on the monitor 57 as shown in FIG. 7, and calculate the reference dimensions of L1, L2 and L3 shown in FIG. 7 from the back shape. . Further, the obesity degree (BMI) of the subject M is calculated based on the height of H, which is the height of the subject M, and the weight from the weight scale 4. Assuming that the height is a and the weight is b, the BMI is obtained by BMI = b / a ² and displayed on the monitor 57. Usually BM
I: 20 or less is thin type, 20 to 24 is normal, 24 to 2
It is said that 6.5 is slightly obese and 26.5 or more are obese.

At the point s and the point r. Note that the measurement point f is set from the point s at the maximum concave position of the waist.

L2 is the amount of protrusion of the back, which is obtained from the difference between the q point and the p point at the measurement point e. The point q is an intersection of the tangent connecting the point o and the point s at the measurement point d at which the neck of the subject M is measured, and the measurement point e. The measurement point e is set from the maximum point p of the back.

Assuming that the maximum protruding point at the measurement point g of the buttocks is t, and that the point at which the tangent connecting the point t and the point p intersects the measurement point c of the head is m, the L3 is the m point And the maximum protrusion point n of the head. That is, this is data necessary when selecting the height of the pillow based on the height of the head, and is not necessary as data for selecting the hardness of the mattress.

The dimensions from the origin (the position of the displacement amount 0 of the detection rod 12) to the maximum protruding point or the maximum dent point at the measurement points c, d, e, f, and g are shown in FIG.
It is calculated as a value indicated by j, k, l.

The reference dimensions L1 and L2 calculated by the processing unit 52 and the BMI are compared by the comparison unit 53 with the set values input from the storage unit 45. That is, the reference dimensions L1 and L2 of a large number of persons to be measured and BM
I is measured, and the subject is laid on each of three mattresses X to Z having different hardnesses to determine which hardness of the mattress is optimal. Then, data relating the mattress having the optimum hardness to the reference dimensions L1, L2 and BMI is input to the storage unit 55.
In addition, if the hardness of the mattress is 100 for X, Y is 8
0 and Z are 60 and become soft sequentially.

As a result, the measurement data of the subject M is processed by the processing unit 52 and compared with a preset value by the comparing unit 53, so that the mattress having a hardness suitable for the subject M is obtained. Can be selected. Below, BM
The values of I, L1, and L2 and the results of the subject M actually selecting a mattress having a hardness suitable for him / her are shown.

Assuming that the criterion is only BIM, if BMI <20, the mattress is Z, if Y 20 ≦ BMI ≦ 24, the mattress is Z, and if Y 24 ≦ BMI ≦ 26.5, the mattress is Y, X 26. If 5 <BMI, the mattress was X.

Assuming that the criterion is only L1, if L1 <3.0, the mattress is X 3.0 <L1 <3.5, the mattress is Y 3.5 <L1, and the mattress is Z. Was.

Assuming that the criterion is only L2, if L2 <4.5, the mattress is X4.5 <L2 <5.0, the mattress is Y5.0 <L2, and the mattress is Z. Was.

Accordingly, for example, from the measurement data of the subject M, in the case of BMI, the hardness of the mattress is preferably Y or Z, Y is good from L1, and Y is good from L2. It is determined that the subject M should use a mattress having a hardness of Y.

The reference dimensions L1 and L2 of the subject M and the BM
Although the mattress having the optimal hardness for the subject M was comprehensively selected from I, these individual data are also stored in the storage unit 55 according to the individual data of L1, L2, and BMI. By comparing with the individual data obtained, a mattress having a hardness suitable for the subject M can be selected.

Further, reference dimensions L1 and L2 of the subject M
Is compared with the reference data stored in the storage unit 55,
A mattress having a hardness suitable for the subject M can be selected without referring to the obesity degree BMI.
