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.

A method of acquiring shape data for assembling a support plate for a customized chair according to an embodiment of the present invention includes acquiring shape data obtained by measuring a body contour of a user in a state in which a spinal posture of a user using the customized chair is maintained in a reference vertebral posture And body shape data is obtained as shape data for forming a support surface of the support plate by assembling.

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 .

4A to 4C, the reference vertebral posture may be determined based on the vertical line passing through the central portion of the cervical vertebra No. 7 (C7) or thoracic vertebra Th1 on the front side of the user, , The cervical vertebrae 7 (C7), the lumbar vertebrae L1 (L1), and the sacrum 1 (Os sacrum) are located substantially on the same vertical line and the vertical line passing through the central part of the cervical vertebrae 7 The cervical vertebrae (C1), the cervical vertebrae (C7), the lumbar vertebrae (L1), and the sacral vertebrae (Os sacrum) are located on the same vertical line. 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. 4A and 4B, a bar type marker M1 may be attached to the valley portion of the back and forth in the vertical direction.

In addition, a line-type marker M2 can be attached and displayed in the vertical direction on the most protruding portion descending downward from both wing bones of the back.

It is also possible to display markers of point type (M3, M4, M5) in a portion determined to be necessary for three-dimensional implementation.

M2, M3, M4, and M5 are displayed on the front and side of the user's body while displaying a plurality of identifiable markers M1, M2, M3, M4, and M5, , M5) 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.

It goes without saying that the shape data can be used as the shape data for the assembled and customized chair of the present invention if shape data corresponding to the reference vertebral posture can be obtained by various other methods than the above-described shape data acquisition method.

The shape data acquired by the above-described method is shape data for assembling a customized chair support plate. Hereinafter, the support surface of the support plate is formed by assembling based on the shape data.

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. 5, the plurality of support plates 410, 420, 430, and 440 of the customized chair and the seat 200 may be configured separately.

The plurality of support plates 410, 420, 430, and 440 may include a neck support plate 410 for supporting a user's neck, a scapular bone supporting part of the user's shoulder blade or the like, A fingerboard 420, an armpit supporting plate 430 supporting the user's side, and a waist pelvis supporting plate 440 supporting the user's waist and pelvis.
