The climbing portion 110 may be provided on the rear side to support the user's back.

Here, side support parts 111 may be formed on the left and right sides of the back plate 110 so as to surround the user's back plate from side to side.

Specifically, the side support portion 111 may be formed to extend to the left and right sides of the back portion 110, and is formed to surround the side of the user's body, covering the user's back and left and right sides when the user sits on the chair. The upper body of the can be supported so that it is vertical.

In addition, the back plate 110 is provided on the front side so that the spine support 112 protrudes so as to form an 'S' shape on the user's spine.

Here, the back support 112 may be formed to protrude from the upper part to the lower part in the middle of the back plate 110 in contact with the user's spine when the user is seated. A portion may be formed to protrude further.

On the other hand, the back panel 110 may be provided with a sensor unit (not shown) that is installed at a position where the user's back touches and measures and transmits pressure.

Here, the sensor unit may use an IR sensor, a fiber sensor, a temperature sensor, a biosensor, a film sensor, and the like, and may be attached to a cushion manufactured using an adhesive. However, it is not limited thereto, and the sensor unit may be any sensor capable of detecting the user's posture as a flexible sensor. A plurality of these sensors may be provided on the backrest part 110, and they do not come into contact when a part of the backrest part 110 does not cover the whole, that is, when the user sits in the correct posture, but the user's posture slips or When it is twisted, a sensor unit is provided only in the contact area so that it can be detected and monitored when there is a deformation in the user's posture, or a sensor unit is provided only in the area contacted when the user is seated to measure the applied pressure and set the pressure If it is smaller than this, it may be provided so that it can be detected and monitored. The data measured by the sensor unit is transmitted to the user's smartphone to guide the user to maintain an upright posture, and the smartphone of a family member or medical person in charge who cares for the user or a digital healthcare network that manages the user's medical data. can be transmitted via

The seat portion 120 is to be seated on the user's buttocks, and may be provided with a cushion 121 stably fixing the user's pelvis.

Here, the seat plate part 120 may be coupled to the seat plate part frame 104 . At this time, the seat plate part 120 is hinged to the rear side of the seat plate part frame 104, so that when the front side of the seat plate part 120 is raised, it can be rotated in the rear direction.

At this time, the cushion 121 is recessed in the area where the right and left ischial tuberosity (IT), coccyx, and greater trochanter (GT) touch the left and right ischial tuberosity (IT) portions where pressure is concentrated when the user is seated. A recessed portion 122 may be formed.

Accordingly, different areas of the cushion 121 in contact with the left and right ischial tuberosity (IT) portions, the coccyx portion, and the greater trochanter (GT) where the pressure is concentrated when the user is seated are in contact with each other. By forming the depression 122, which is more depressed than the area, the left and right ischial tubercles, the coccyx, and the large protrusion of the femur do not come into contact with the cushion 121 when the user is seated, and apply pressure to the rest of the area except for the corresponding areas. It is evenly distributed, and the user's buttocks and thighs are accommodated to hold the pelvis, preventing the user from moving when sitting, thereby maintaining an upright posture.

That is, the side support part 111 of the back part 110 holds the user's torso as if wrapping it, and maintains an ideal neutral posture through the cushion 121 in which the recessed part 122 is formed, so that the seated user's pelvis It is possible to prevent the spine from being deformed into lordosis by bending the torso forward, or by taking an asymmetrical posture with the torso to the left or right.

The tilting unit 130 is provided under the seat plate 120 to tilt the seat plate 120 .

Here, the tilting part 130 may be a cylinder, one end of which is coupled to the lower surface of the seat plate 120, and the front side of the seat plate 120 is raised and lowered to adjust the tilt of the seat plate 120.

At this time, one end of the tilting part 130 may be rotatably coupled to the front lower surface of the seat plate part 120 . In addition, the other end of the tilting part 130 may be coupled to the tilting part coupling part 130 formed in the vertical direction of the frame 102 .

Accordingly, when the tilting part 130 is driven, the front side of the seat plate part 120 is raised. At this time, the rear lower part of the seat plate part 120 is hinged to the rear side of the seat plate part frame 104, so that when the front side of the seat plate part 120 is raised, the seat plate part 120 is rotated in the rear direction so that the inclination can be changed. have. That is, when the tilting unit 130 is driven, the seat plate unit 120 can be tilted so that the user's posture can be changed.

In general, when sitting in a chair for a long time, the body naturally wants to move, and it is a natural phenomenon to change posture, such as crossing legs, bending forward at the waist, or leaning sideways. So even if you sit in a neutral posture, you keep getting a deformed posture without knowing it. To prevent this, the recline function is used to make the back of the chair recline when you push the back of the chair back. However, the recline function allows you to relax your body a bit by stretching your back and increasing the angle of your lower back, but pushing your hips forward as you come back. So, shear force is generated at the hip, and the body slides forward, the waist cannot maintain the 'S' shape, and the lumbar spine curves in the opposite direction, resulting in many people having a spinal disease called disc herniation.

However, in the case of tilt, the seat portion 120 is tilted back as a whole in a state in which the back portion 110 is fixed to the seat portion 120 while maintaining the angle of the hip joint, the knee joint, and the ankle joint close to vertical, respectively, resulting in a neutral posture. Since it is tilted without being disturbed, you can take a sufficient rest in the tilted position, and even if you come back to the front, you can work again while maintaining the neutral position. Therefore, by applying the tilt function, diseases such as spinal deformation and disc herniation can be prevented from occurring while sitting for a much longer time than the recline function.

The footrest portion 140 is fixedly coupled to the front surface of the seat portion 120 in a vertical direction to support the user's feet.

At this time, the footrest portion 140 may be coupled vertically to the seat portion 120 so that the user's ankle, knee, and hip joints each form a 90° angle. Accordingly, the user can maintain a neutral posture, which is an upright posture in which the ankle, knee, and hip joints each maintain a 90° angle.

After all, the chair for posture correction according to the embodiment of the present invention has a neutral posture, which is an ideal sitting posture, through the side support part 111 that surrounds the user's back and the seat part 120 and footrest part 140 that fix the user's pelvis. It is difficult to sit in the neutral posture of the chair for a long time, so it is often tilted through the tilting part 130 to relieve fatigue and to maintain the ideal sitting posture, neutral posture, for a long time. It prevents pain and maintains ideal spinal alignment.

So far, the present invention has been looked at with respect to its preferred embodiments.
