Description

{CHAIR FOR GUIDING CORRECT POSTURE}

More particularly, the present invention relates to a chair for attitude induction, and more particularly, to a chair for positioning a seat in which a central axis of the seat is located at the center, and when the user's pelvis sits rearwardly inclined or forwardly inclined while sitting on a seat, And to induce the user to sit forward or backward to be inclined so as to adjust the weight to the center axis of the seat, thereby allowing the user to make a correct posture by himself / herself.

Most of the common chairs are located behind the central axis of the seat so that the seat is flattened even if the user sits in the seat. Such a chair would be uncomfortable because the user's pelvis would be inclined rearward while the user sat on the seat, or the center of the body would move toward the tail bone when the vertebrae were backed up and the seat would not come down smoothly forward. It is often the case. As a result, the pelvis tilts backward at an inconsistent position in the chair, causing the vertebrae to bend without being straightened up, causing back pain or spinal-related diseases. This inadequate attitude can also be a source of scoliosis, especially for students, teens, and workers who sit in chairs for long periods.

To solve these problems, various techniques for a posture correcting chair have been disclosed.

For example, the 'chair tilting device' of Korean Patent Registration No. 10-0968547 (published on Jul. 2010) and the 'posture correction chair' of Korean Patent Registration No. 10-1033027 .

The tilting device of Korean Patent Registration No. 10-0968547 allows the rotation center of the back plate to be positioned at the hip joint of the user without providing a joint structure at the upper side of the seat, So that the seat plate and the back plate are inclined together.

 In addition, since the posture correction chair of Korean Patent Registration No. 10-1033027 adjusts the inclination of the seat by the posture correction unit, it is possible to correct the posture of the user who is seated on the inclined seat, , The slope of the seat plate is tilted forward, so that there is a risk that the weight shifts to the front and causes fall.

The above-described techniques have a difficulty in commercializing a product such as a configuration for posture correction is still complicated and a manufacturing cost is increased accordingly.

Fig. 1 is a side view showing a configuration of a chair for posture induction according to the present invention, and Fig. 2 is a front view of the chair for posture guidance shown in Fig. 1. Fig.

1 and 2, the posture induction chair 100 according to the present invention is constructed in such a manner that the central axis 130 of the warp induction seat 120 is positioned at the center of both sides of the frame 110, 120), when the user's pelvis is inclined rearward or kyphosis occurs, or when the user's pelvis is inclined forward or the vertebrae is lordosis, the user feels uncomfortable, Inducing seat 120 to guide the seat 120 to be inclined forward or backward through the central axis 130 in order to align with the center axis 130 of the seat 120,

Specifically, the posture induction chair 100 of the present invention includes a frame 110, a warp induction seat 120, a center shaft 130, and first and second angle restraining shafts 140 and 150 . Further, the posture induction chair 100 of the present invention further includes a backrest 160 and first and second guide cushions 170 and 180.

The frame 110 forms the body of the posture-inducing chair 100. The frame 110 has, for example, a horizontally symmetrical structure, and a center shaft 130 is coupled between both sides. The center shaft 130 is fixed at the center in the longitudinal direction of the frame and penetrates the center of the inclined induction seat 120 in the longitudinal direction.

That is, the frame 110 includes a plurality of legs 112 for supporting the floor surface, and a plurality of legs 112 provided on the legs 112 to fix the center shaft 130 in such a manner that the inclined induction seat 120 can be rotated forward and backward And a backrest support 116 which is provided on the upper portion of the seat support 114 and fixes the backrest 160.

The frame 110 of this embodiment is provided integrally with the legs 112, the seat support 114 and the back support 116, but each of the legs 112 to 116 may be provided separately.

The warp induction seat 120 is provided with a center shaft 130 coupled between both sides of the frame 110 and disposed at the center in the front-rear direction and is rotatable at a predetermined angle in the front-rear direction. That is, the warp induction seats 120 are provided between the two sides of the seat support 114. At this time, the warp induction seat 120 is penetratedly coupled so that the center shaft 130 coupled to the center of the seat support base 114 in the front-rear direction is located at the center thereof.

When the user sits down, the slope-inducing seat 120 may feel uncomfortable when the user's pelvis is inclined rearward or kyphosis, and the weight of the slope inducing seat 120 may be set to be inclined forward along the central axis 130 . In addition, the slant induction seat 120 can induce the user to self-weight his / her body to sit rearwardly inclined along the central axis 130 when the user sits, when the user's pelvis is inclined forward or when the vertebrae is lordosis . As a result, the incline-inducing seat 120 guides the user to make a correct posture.

The first angle restricting shaft 140 is, for example, for restricting the rotation angle in the forward direction (? 1 in FIG. 3), and is located at the lower front end of the warp induction seat 120 and fixed to the frame 110. The first angle restricting shaft 140 restricts the inclination angle of the inclined induction seat 120 to the front.

The second angle restricting shaft 150 is located at the rear lower end of the warp induction seat 120 and is fixed to the frame 110. The second angle restricting shaft 150 limits the angle of rotation (? 2 in FIG. 4) that is inclined rearward of the warp induction seat 120. The second angle restricting shaft 150 of this embodiment is located at the upper part between the legs located on the both rear sides.

In the embodiment of the present invention, the angle? 1 at which the warp induction seat 120 is inclined forward is smaller than the angle? 2 at which it is inclined backward. This is because an incline forward is more uncomfortable than a backward incline. In other words, since the posture for increasing the load on the user's knee joint is induced when the slant induction seat 120 is tilted forward, the first angle restricting shaft 140 is positioned at the bottom of the slant induction seat 120, It is preferable that the second angle limiting axis 150 is provided at a position of the frame 120 higher than the second angle limiting axis 150. [

The backrest 160 is provided at the upper rear of the frame 110 and is provided to support the user's back. That is, the backrest 160 is mounted on the backrest support 116. The backrest 160 is provided with a plurality of first and second guide cushions 170 and 180 protruding in the forward direction.

The first guide cushion 170 guides the user's thoracic spine. The first guide cushion 170 is located at an upper portion of the backrest 160 and a plurality of the first guide cushions 170 protrude from the backrest 160 in a forward direction at a predetermined height corresponding to the user's thoracic position.

The second guide cushion 180 guides the user's lumbar support. The second guide cushion 180 is located at a lower portion of the first guide cushion 170, and a plurality of the second guide cushions 180 protrude from the backrest 160 in a forward direction at a predetermined height corresponding to the lumbar position of the user.

At least one of the first and second guide cushions 170 and 180 may be provided. In this embodiment, each of the first and second guide cushions 170 and 180 is provided corresponding to the left and right sides of the user's thoracic or lumbar spine.

Next, a process of inducing the correct posture by the posture induction chair of the present invention will be described.

FIG. 3 is a view showing a state where the user's pelvis is seated on the posture-inducing chair according to the present invention when the user's pelvis is inclined forward; FIG. 4 is a view illustrating a state where the posture is adjusted when the user's pelvis is seated rearwardly Fig.

Referring to FIG. 3, when the user sits in the chair 100 according to the present invention, when the center of gravity of the user moves forward and the slant induction seat 120a is inclined forward by a certain angle? 1, The user himself or herself moves the center of gravity rearward and the warp induction seat 120 is rotated in the direction of the second angle restricting shaft 150 along the central axis 130 so that the warp induction seat 120 is adjusted in a flat state .

Referring to FIG. 4, when the user sits on the posture induction chair 100 of the present invention, when the center of gravity of the user moves backward and the inclined induction seat 120b is inclined rearward by a certain angle? 2, The vertebrae of the spine are not allowed to sit up straight and bend. The user himself or herself moves the center of gravity forward to rotate the warp induction seat 120 in the direction of the first angle limiting shaft 140 along the central axis 130 so that the warp induction seat 120 is adjusted in a flat state do.

Therefore, as shown in FIGS. 3 and 4, when the user sits forward or backward, he / she feels uncomfortable by himself / herself, and corrects his / her postures so as to move backward or forward along the central axis 130, Allow yourself to maintain posture control. Accordingly, the posture induction chair 100 according to the present invention allows the user's pelvis to sit in a neutral position or slightly forward slope, so that the user's body including the waist can stand upright.

Accordingly, most of the existing chairs are designed to flatten the seat even if the seat center is located rearward. However, in the present invention, the seat center axis of the chair is designed to be located at the center, and when the user sits on the seat of the chair When the pelvis is inclined rearward or inclined forward, the center of the body moves toward the tail bone, so that the chair can not come down smoothly. Therefore, the user feels uncomfortable and corrects his / her posture. This allows the pelvis to be tilted in a neutral position or slightly forward, thus inducing correct posture.

And FIG. 5 is a view showing the positions of the plurality of guide cushions shown in FIG.

Referring to FIG. 5, the posture induction chair 100 of the present invention includes a plurality of guide cushions 170 and 180 on the backrest 160 to properly guide the user's posture.

The first guide cushion 170 is a thoracic guide cushion and the second guide cushion 180 is a lumbar guide cushion to prevent back pain caused by the posture of the user and to restrain his or her posture Provides guidelines for correcting errors.

Since the first and second guide cushions 170 and 180 are provided corresponding to the thoracic and lumbar spine of the user, it is possible not only to prevent scoliosis, which is frequently generated in the growing-age students, As scoliosis is very difficult to recover, it is possible to correct the position by calling for the position of the guideline so that it can be prevented in advance.
