DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

The customized chair according to an embodiment of the present invention includes at least a support plate for supporting the back portion of the user, and a seat plate for supporting the buttocks and thighs.

The method of acquiring shape data for machining or assembling a customized chair support plate according to an embodiment of the present invention includes measuring a shape of the user's body in a state in which a spinal posture of a user who uses the customized chair is maintained in a reference spinal posture And the shape data obtained as the shape data for forming the support surface of the support plate by machining or assembling.

In order to obtain shape data for forming the support surface of the support plate, body shape data obtained by measuring the body contour of the user is acquired as shape data for forming the support surface of the support plate.

The user's spinal posture is required to be maintained in the reference spinal posture when measuring the body contour of the user.

This is because the support plate made based on the shape data obtained by measuring the user's body contour while the user's spinal posture is not in the reference vertebral posture due to an incorrect posture maintains the user's spinal posture in an incorrect posture .

4, the reference vertebral posture is determined based on the vertical line passing through the central portion of the cervical vertebra No. 7 (C7) or the thoracic vertebra No. 1 (Th1) on the front face of the user, (C7), lumbar 1 (L1), and sacrum 1 (Os sacrum) are positioned on substantially the same vertical line, and as shown in Fig. 5B, a vertical line passing through the central portion of cervical vertebra The cervical vertebrae 1, the cervical vertebra 1, the lumbar vertebra 1, and the lumbosacral vertebra 1 are located substantially on the same vertical line. Is a vertebrae posture.

More preferably, the reference vertebral posture is a cervical vertebra of the cervical vertebrae C1, the cervical vertebrae 7 (C7), the cervical vertebrae 7 (C7), the cervical vertebrae 7 (C1), cervical vertebrae (C7), cervical vertebrae (C7), and cervical vertebrae (C7) with the deviation of lumbar vertebrae (L1) ), Lumbar spine L1 (L1), and sacrum 1 (Os sacrum) within 2cm. The cervical vertebrae are 30 ° ~ 50 ° and the thoracic spine is 20 ° ~ 50 ° posterior. The lumbar spine is 30 ° ~ 70 ° It is the vertebral posture that becomes the prelude of.

Medically, the entire vertebrae measurement after standing is common. However, since this embodiment relates to a customized chair, it aims at satisfying the above-described reference vertebral posture in a seated posture of the user.

Meanwhile, the maintenance of the reference vertebral attitude as described above may be performed through X-ray radiography on the front and side of the user, respectively, while maintaining the vertebral posture of the user to be the reference vertebral posture.

For example, the digital X-ray technique can be used to perform X-ray radiography on the front and side of the user, respectively, and to calibrate the user's spine posture in real time so that the user's spine posture can become the reference spine posture.

In addition to the X-ray photographing, the user's body photograph data may be supplementarily referred to to maintain the user's spine posture to be the reference vertebral posture.

As described above, in a state in which the spinal posture of the user using the customized chair is held in the reference spinal posture, the measurement of the body contour for obtaining the user's body shape data can be performed through the two-dimensional photographing or the three-dimensional photographing.

The two-dimensional photographing may be, for example, X-ray, photographing, computed tomography (CT), or the like.

Computed tomography has a limit on the number of shots because it radiates approximately 400 times more radiation than X-rays.

Therefore, in the case of two-dimensional photographing, X-ray or photographing is preferable.

The three-dimensional imaging may be, for example, three-dimensional scanning, magnetic resonance imaging (MRI), or the like.

3-D imaging such as magnetic resonance imaging is excellent in accuracy and convenience of measurement, but is expensive.

Therefore, in the case of three-dimensional photographing, it is preferable to take a 3D scanning method. For example, body shape data can be obtained by non-contact measurement of the user's body contour using a non-contact 3D laser scanner or the like.

Since there are many known techniques for 3D scanning, the theoretical explanation is omitted.

As described above, by using a photographing method such as X-ray, photographing, computed tomography (CT), three-dimensional scanning, magnetic resonance imaging (MRI) Can be measured.

Hereinafter, the measurement of the body contour of the user using the X-ray imaging method will be specifically described.

A front X-ray photograph and a side X-ray photograph obtained by performing X-ray photographing based on the front and side of the user in a state in which the spinal posture of the user using the customized chair is maintained in the reference vertebral posture, .

The body contour of the user can be measured while supplementally referring to the photograph of the user's body in addition to the X-ray photographing.

The front X-ray photograph and the side X-ray photograph obtained by the X-ray photograph are photographs of the body.

It is relatively easy to identify the overall outline of the body based on these photographs, but it may be relatively difficult to identify the appearance of the valleys or the side of the spine, such as the spine.

Therefore, a radiation marker can be used to easily recognize the contour of a valley part such as a vertebra or a curved part of a flank.

The radiation marker may be made of a metal, a contrast agent, or the like and may be used attached to the user's body.

That is, before radiography, at least one radiation marker of mutually distinguishable form is attached and displayed on a main part of the user's body to be photographed, and X-ray is taken in this state.

For example, in the case of a linear radiation marker, the thickness of each radiation marker may be different, and in the case of a point-like radiation marker, the size or shape of each radiation marker may be varied to make each radiation marker distinguishable .

Referring to FIGS. 4 and 5A, a bar type marker 310 may be attached to the valley portion of the back side in the vertical direction.

In addition, a line-type marker 320 may be attached and displayed in the vertical direction on the most protruding portion descending downward from the two wing bones of the back and the like.

In addition, markers of point type (330, 340, 350) can be displayed in a portion determined to be necessary for three-dimensional implementation.

As described above, when the front and the side of the user's body are X-rayed while displaying a plurality of

markers

310, 320, 330, 340 and 350 which are distinguishable from one another, 350 can more easily implement the three-dimensional shape of the user's body contour.

In addition to the above-mentioned methods, it is also possible to divide the radiographic markers by assigning unique indications or unique identifiers to the radiographic markers, or by wearing X-ray radiographs of clothes marked with a plurality of identifiable radiation markers.

As described above, the body contour of the user is measured through the two-dimensional photographing or the three-dimensional photographing while the spinal posture of the user using the customized chair is maintained in the reference vertebral posture, and the body shape data of the user thus obtained is stored in the customized chair As the shape data for forming the supporting surface of the supporting plate provided.

The shape data obtained by the above-described method is shape data for machining or assembling a customized chair support plate. Hereinafter, formation of the support surface of the support plate on the basis of the shape data will be described.

First, the support surface of the support plate is formed by machining.

The formation of the support surface of the support plate by machining means forming the support surface for supporting the back portion of the user as the support surface of the support plate is processed based on the shape data.

For example, as shown in Fig. 6, the support plate 100a and the seat plate 100b of the customized chair may be integrally formed, or the support plate 200a and the seat plate 200b may be separated and connected to the supporter 260.

Each of the

support plates

100a and 200a is formed so as to surround a rear portion of an upper half of a user including a user's back, neck, shoulder, side, waist and the like and the

support plates

100a and 200a, The support surface supports the back portion of the user.

Accordingly, the user's spinal posture can be calibrated and maintained in the reference spinal posture by the supporting surfaces of the

respective support plates

100a and 200a.

In addition, for example, as shown in FIG. 7B, the support plates 200a1, 200a2 and 200a3 of the customized chairs are separated from the seat 200b by the support table 260, and the support plates 200a1, 200a2 and 200a3 ) May be divided into a plurality of parts.

At this time, the plurality of support plates 200a1, 200a2, 200a3 may be configured to individually support the neck portion 200a1, the one side back portion 200a2, and the other side back portion 200a3 of the user.

On the other hand, the individual support surfaces of the respective support plates 200a1, 200a2, 200a3 are each processed based on the shape data, and the entire support surface formed by the combination of the individual support surfaces totally supports the back portion of the user, Thus, the user's spinal posture can be calibrated and maintained in the reference spinal posture.

Meanwhile, the support surfaces of the

support plates

100a, 200a, 200a1, 200a2, and 200a3 based on the shape data can be processed through various mechanical processes such as cutting, injection, pressing, and the like.

For example, the base material such as synthetic resin or wood can be cut by the above-mentioned shape data using a cutting tool such as CNC.

Alternatively, an injection surface based on the shape data may be formed in the mold, and the support plate may be injection-molded with synthetic resin.

Alternatively, the metal plate can be pressed through a mold surface based on the shape data.

As described above, the support surface of the support plate can be formed through various mechanical processes.

It is needless to say that the cushioning material may be attached to the surface of the support plate made of synthetic resin, metal, wood or the like.

As described above, as the support surface of the support plate is processed to support the user's back, the user's spinal posture can be calibrated and maintained in the reference spinal posture.

Next, the formation of the supporting surface of the support plate will be described.

The formation of the support surface of the support plate means that the support plate is assembled such that the entire support surface formed by the combination of the individual support surfaces of the plurality of support plates has a shape based on the shape data.

For example, as shown in FIG. 9, a plurality of

support plates

810, 820, 830, and 840 of the customized chair and a seat plate 600 may be configured separately.

The plurality of

support plates

The individual support surfaces of the

respective support plates

810, 820, 830 and 840 individually support the neck, shoulders, armpits, waist and pelvis of the user, and the entire support surface formed by the combination of the individual support surfaces, And the support plate is assembled so as to have a shape based on the shape data.

Accordingly, the entire support surface formed by the combination of the individual support surfaces of the

respective support plates

810, 820, 830, 840 supports the back portion of the user as a whole, thereby correcting the user's spinal posture to the reference spinal posture Can be maintained.
