The present invention relates to a method for extracting a bed mattress according to the characteristics of a human body, and more specifically, a bed mattress according to the characteristics of a human body in which a most suitable and comfortable bed mattress can be selected using a database of body shape, spine shape and body pressure. It relates to an extraction method.

Human body shape is not a flat shape, various bends are formed, and each part has a different weight.

Thus, if a person is lying in bed, the distribution of pressure at the contact surface between the bed and the lying person, that is, the distribution of body pressure, varies from person to person. By the way, the bed mattress has been produced uniformly regardless of the human body shape.

The uniformly made bed mattress is comfortable for a bed mattress that fits an individual's body shape and the body pressure is properly distributed due to the different body shapes and body pressures of the human being. You can not sleep on the mattress.

This phenomenon can be seen by comparing the distribution of body pressure in a bed suitable for the body shape and a bed not suitable for the body type shown in FIG. 1.

The body pressure of the shoulder and hip is a symmetrical form in which proper pressure is distributed, and the shape in which the pressure is not concentrated on the other side is good for taking a good night's sleep.

On the other hand, as an example of the body pressure distribution in the bed which is not suitable for the body shape, the body pressure is not concentrated or evenly distributed in one place, so that a correct posture cannot be maintained (FIG. 1B).

In addition, since the body pressure distribution of the head, the body, the buttocks and the legs, which are the main parts of the body, are different, the body pressure distribution of each person is different in the uniformly manufactured bed mattress.

Therefore, it is difficult to manufacture a standard bed mattress that can accommodate the body pressure distribution of various people, and for this reason, a large number of people do not properly distribute the body pressure distribution in the bed, can not achieve a good sleep, tired due to uncomfortable sleep This cumulative problem occurs.

Accordingly, the present invention has been made to solve the problems described above, using a database of body shape, spine shape and body pressure is a bed mattress extraction method as a human characteristic that can be selected the most suitable and comfortable bed mattress for a specific person The purpose is to provide.

A preferred aspect for achieving the above object of the present invention comprises a first step of measuring the body pressure of a specific person; A second step of obtaining the inclination of the bed mattress with respect to the sequentially applied load and the depth pressed by the load with the measured body pressure of the first step; There is provided a bed mattress extraction method as a human body characteristic, comprising a third step of extracting a comfortable bed by comparing the inclination of the obtained bed mattress with a predetermined inclination of the plurality of bed mattresses.

Hereinafter, exemplary embodiments of the present invention will be described with reference to the accompanying drawings.

The present invention calculates the body loyalty index by sex, height, and weight, classifies Koreans into 18 types, and builds a body characteristics database as shown in Table 1.

18 subjects having the 18 body types shown in Table 1 were selected and shown in FIG. 2 using a Micro Scrive-3DLX device (a measuring device for calculating coordinate points on a three-dimensional position of the point measured from the origin). Similarly, in standing position, the 7th cervical point (C7) of the spine of the subject, the point between the 4th and 5th lumbar vertebrae (L4 / L5), the sacrum point and the C7 and L4 The spine shape of the subject was measured by calculating a three-dimensional coordinate point at the points (P1, P2, P3) divided into four quarters / L5.

And, as shown in Figure 3, 13 bed mattresses were selected, this flexural diagram measuring the depth pressed according to the load was converted into a log function slope, as shown in Table 2.

When 18 subjects were lying on each of the 13 bed mattresses having this inclination, the spine shape of the subject was measured by plastering the spine shape of the subject.

end. Male and female body types: Among the 18 body types, the standing posture and lying spine shape of the male standard body subjects were slightly different for each bed mattress, but the standing posture and bed mattress of the female standard body subjects were slightly different. The lying spine shape did not show any changed shape on most mattresses.

In other words, it can be seen that the bed mattress for each experiment fits the female standard type more than the male standard type.

I. Male general body size: Among the male subjects, the obese body subjects showed a substantially similar spine shape when lying down and the spine shape when lying down. On the contrary, the skinny subjects lie down with the spine shape when standing. The spine shape was very different.

All. Female general body type: Female subjects showed a lot of personal differences unlike males. Female subjects with the standard body type had good results for each bed mattress, and the general body type showed a big difference among the subjects.

Therefore, women's general body shape is very different from the standing spine shape and the lying spine shape.

In the present invention, in constructing a database on the shape of the spine, the spine state of the standing subject and the five bed mattresses (A, B, C, D, and E) among the 13 bed mattresses are laid on each mattress. By comparing the spine shape of the subjects at the time, using the root mean square (RMS) root mean square (RMS) was extracted to present the appropriate mattress for each body type.

Here, the cervical points (C7) of the vertebrae when standing and the vertebral shape when standing on each five-bed mattress are matched, and the vertebral shape when standing and each five-bed mattress. Spine shapes when lying on the bed were compared.

First, in the case of the standard body type, as shown in Table 3, it was shown that the female was better suited to the bed mattress than the male, with the root mean square value close to each mattress.

In addition, the mean deviation square root value is the smallest in the A and B bed mattresses for men, and the A and B bed mattresses are comfortable mattresses.
