In the following description of the present invention, if it is determined that the detailed description of the related known technology may obscure the gist of the present invention, the detailed description thereof will be omitted.

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

Shape data acquisition method for processing or assembling the support plate for a customized chair according to an embodiment of the present invention, the body posture of the user who will use the customized chair is maintained in the reference spine posture, the user's body appearance is measured The obtained body shape data is obtained as shape data for forming the support surface of the support plate by machining or assembly.

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

When the user's body shape is measured, it is required that the user's spine posture is maintained at the reference spine posture.

This is because the support plate manufactured based on the shape data obtained by measuring the user's body shape while the user's spine posture is not the standard spine posture due to an incorrect posture maintains the user's spine posture in the wrong posture. .

The reference spine posture, as shown in Figure 4, cervical spine No. 1 (C1), cervical spine 7 on the basis of the vertical line passing through the central portion of the cervical spine 7 (C7) or thoracic spine 1 (Th1) on the front of the user Nos. C7, lumbar spine No. 1 (L1), and sacral Nos. 1 (Os sacrum) are located on substantially the same vertical line, and as shown in FIG. 5B, a vertical line passing through the central portion of cervical spine No. 7 (C7) on the side surface. Cervical spine No. 1 (C1), cervical spine No. 7 (C7), lumbar spine No. 1 (L1), sacral No. 1 (Os sacrum) are located on substantially the same vertical line, the cervical spine only before, after the thoracic spine, lumbar spine Is the spine posture only.

More preferred reference spine posture, cervical spine No. 1 (C1), cervical spine No. 7 (C7) based on the vertical line passing through the cervical spine 7 (C7) or thoracic spine 1 (Th1) on the front of the user standing or sitting ), Lumbar spine 1 (L1), cervical spine 1 (Os sacrum) deviation within 1cm, on the side, cervical spine 1 (C1), cervical spine 7 (C7) on the vertical line passing through cervical spine 7 (C7) ), The lumbar spine 1 (L1), the sacral spine 1 (Os sacrum) deviation within 2cm, cervical spine only before 30 ° -50 °, thoracic spine after 20 ° -50 °, lumbar spine 30 ° ~ 70 ° It is the spine posture that is only before.

Medically, after standing, the measurement of the total spine is common, but since the present embodiment relates to a customized chair, the user aims to satisfy the above-described reference spine posture in a seated position.

On the other hand, the maintenance of the reference spine posture as described above, can be made through the process of maintaining the spine posture of the user to the reference spine posture while X-ray imaging in each of the front and side of the user.

For example, it may be achieved through a process of correcting in real time such that the spine posture of the user can be the reference spine posture while X-ray imaging from the front and side of the user using digital X-ray technology, respectively.

In addition to the X-ray imaging, the user's spine posture may be maintained to be the reference spine posture with reference to the user's body photograph data.

As described above, with the spine posture of the user who will use the customized chair finally maintained as the reference spine posture, the measurement of the body shape for obtaining the body data of the user may be performed through two-dimensional imaging or three-dimensional imaging.

The 2D imaging may include, for example, X-ray imaging, photography, and computed tomography (CT).

Computed tomography has a limit on the number of shots in that it emits approximately 400 times more radiation than x-rays.

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

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

Three-dimensional imaging, such as magnetic resonance imaging, has excellent measurement accuracy and convenience, but at a high cost.

Therefore, in the case of 3D imaging, 3D scanning is preferable. For example, the body shape data of the user may be obtained by non-contact measurement using a non-contact 3D laser scanner or the like.

Since a number of known techniques have been proposed for 3D scanning, the theoretical description thereof will be omitted.

As described above, the appearance of the body using imaging methods such as X-ray, photography, computed tomography (CT), three-dimensional scanning, magnetic resonance imaging (MRI), and the like. Can be measured.

Hereinafter, to describe in detail the measurement of the user's body appearance using the X-ray imaging method.

The body shape of the user using front and side X-ray images obtained by X-ray imaging based on the front and side of the user while maintaining the spine posture of the user who will use the customized chair Measure

In addition to the X-ray photographing, the appearance of the user may be measured while assisting the photograph of the user's body.

Front X-ray images and side X-ray images obtained by X-ray photographing are photographs of the body.

Although it is relatively easy to identify the overall contour of the body based on such a picture, it may be relatively difficult to identify the appearance of the valley, such as the vertebral passage and the curved portion of the side.

Therefore, the radiation marker can be used to easily recognize the appearance of the valley portion, such as the back of the spine, the curved portion of the side.

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

That is, before X-ray imaging, at least one radiation marker in a form that can be distinguished from each other is attached to the main part of the user's body to be photographed, and X-ray imaging is performed in this state.

For example, in the case of linear radiation markers, the thicknesses of the radiation markers may be different, and in the case of pointed radiation markers, the radiation markers may be distinguishable from each other by varying the size or shape of each radiation marker. Can be.

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

In addition, a row type marker 320 may be attached to the most protruding portion descending from both wing bones of the back in the vertical direction.

In addition, the

markers

330, 340, and 350 of the point type may be displayed on portions determined to be necessary for the 3D implementation.

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

distinguishable markers

310, 320, 330, 340, and 350, the

markers

310, 320, 330, 340 350, it is possible to more easily implement the three-dimensional shape of the user's body appearance.

In addition to the above-described methods, a method of assigning a distinctive mark or a unique identifier to each radiation marker and distinguishing them or performing X-ray imaging using a garment in which a plurality of identifiable radiation markers are displayed are also possible.

As described above, while the spine posture of the user who will use the custom chair is maintained as the reference spine posture, the user's physical appearance is measured by two-dimensional or three-dimensional imaging, and the user's body data thus obtained is transferred to the customized chair. It can obtain as shape data for forming the support surface of the support plate with which it is provided.

The shape data obtained by the method as described above is shape data for processing or assembling the support plate for the customized chair. Hereinafter, the formation of the support surface of the support plate based on the shape data will be described.

First, the formation of the support surface of the said support plate by processing is demonstrated.

Forming the support surface of the support plate by processing means forming a support surface for supporting the back 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 are integrally formed, or as shown in FIG. 7A, the support plate 200a and the seat plate of the customized chair ( 200b) may be formed to be separated and connected to the support 260.

Each of the

support plates

100a and 200a is formed to surround the upper body rear part of the user's upper body including the user's back, neck, shoulders, side, waist, and the like, and is processed based on the shape data of the

support plates

100a and 200a. The support surface supports the user's back.

Therefore, the spine posture of the user can be corrected and maintained by the reference spine posture by the support surfaces of the

respective support plates

100a and 200a.

In addition, for example, as shown in Figure 7b, the support plate (200a1, 200a2, 200a3) and the seat plate 200b of the customized chair is separated and connected to the support 260, the support plate (200a1, 200a2, 200a3) ) May be divided into a plurality of configurations.

On the other hand, the individual support surfaces of each support plate 200a1, 200a2, 200a3 are respectively processed based on the shape data, and the entire support surface formed by the combination of these individual support surfaces supports the back of the user as a whole. Accordingly, the user's spine posture may be corrected and maintained with the reference spine posture.

On the other hand, the support surface processing of the support plate (100a, 200a, 200a1, 200a2, 200a3) based on the shape data can be performed through a variety of mechanical processing-cutting, injection, press, and the like.

For example, base materials such as synthetic resin and wood can be cut by the shape data using cutting tools such as CNC.

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

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

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

On the other hand, by attaching a cushioning material to the surface of the support plate made of synthetic resin, metal, wood, etc. as described above can of course impart a cushion.

As described above, as the support surface of the support plate is processed to support the user's back part, the user's spine posture can be corrected and maintained with the reference spine posture.

Next, the formation of the support surface of the said support plate by assembly is demonstrated.

Forming the support surface of the support plate by assembly means assembling the support plate such that the entire support surface formed by the combination of the individual support surfaces of the plurality of support plates becomes a shape based on the shape data.

For example, as illustrated in FIG. 9, the plurality of

support plates

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

The plurality of

support plates

810, 820, 830, and 840 may include a neck support plate 810 supporting a user's neck, a shoulder support plate 820 supporting a user's shoulder, an armpit support plate 830 supporting a user's armpit, It may be divided into a waist pelvic support plate 840 supporting the user's waist and pelvis.

The individual support surfaces of each of the

support plates

810, 820, 830, and 840 individually support the user's neck, shoulder, armpits, waist and pelvis, and the entire support surface formed by the combination of these individual support surfaces is The support plate is assembled to have a shape based on shape data.

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

support plates

810, 820, 830, and 840 supports the back of the user as a whole, and accordingly, the user's spine posture is corrected to the reference spine posture. Can be maintained.
