Description

{A SITTING POSTURE CORRECTION CHAIR}

More particularly, the present invention relates to a seat for an orthodontic appliance for rehabilitation therapy, in which a patient having an unbalanced body adjusts the height of the seat by adjusting the height of the seat partially in a sitting position.

In the case of a person with a physical disability, the bones and muscles are distorted due to a long time of wrong postures, and many efforts are made to correct them, but they often fail to return to normal. Typically, long-lying patients with spinal cord injuries, stroke, traumatic brain injury, cerebral palsy, or hemiparesis or limb paralysis have long-lying patients, as opposed to stabilized trunk conditions, with mostly lumbar kyphosis, .

In the case of rehabilitation for patients who can not behave for a long period of time or have an imbalance in their body, rehabilitation of the abnormally changed trunk and pelvis is preceded by rehabilitation of the procedure. Muscles are often shortened, which makes them difficult to treat and the duration of treatment is very long, which puts considerable burden on patients and therapists.

Therefore, there is a need for a seat for orthodontic correction that enables efficient treatment by implementing mechanical movement of the therapist in the rehabilitation treatment for stretching and restoring the joints and contracted muscles constructed during treatment .

FIG. 1 is a perspective view of a chair according to an embodiment of the present invention. . In this case, it is preferable to provide a means for adjusting the height of the entire chair according to the height of the user and the therapist. Since this is a known technique for controlling the height of the entire chair, detailed description thereof will be omitted.

In addition, a belt-type fixing means may be provided to hold the user sitting on the seat plate 110 so as to prevent the user from falling down. Since this is a well-known structure in the posture correcting means for general rehabilitation treatment, .

FIG. 2 is a partial perspective view showing a divided state of the seat according to the present invention. In the present invention, the seat plate 110 is composed of a plurality of seat plates 111 in a divided shape in which the user's buttocks contact. 2 (a) shows a state of the seat plate 111 divided into two parts on the left and right sides, and FIG. 2 (b) shows the state of the seat panel 111 divided into two parts on the left and right sides And shows the state of the seat plate 111 divided into four in total by dividing the divided seat plate into two upper and lower parts.

In general, a user who needs posture correction needs to balance his / her body symmetry so that it is necessary to balance the balance. Therefore, in the preferred embodiment of the present invention, the left and right seat panels 111 are basically provided, If a more precise correction is required, such as body anomalies in the anteroposterior direction, an appropriate number of the seat panels 111 can be divided and formed as necessary.

 The seat plate 110 is provided with elevating and lowering means 113 for individually adjusting the height of the seat plate 111 under the divided seat plates 111. [ The lifting and lowering means 113 raises the seat plate in a direction tilted to correct the tilted body by the user due to the unbalance while the user is sitting on the seat plate 111 to an appropriate height, will be.

If the seat 111 is divided into a large number and has a relatively small size, one actuator 114 may be provided for each seat, but the seat 111 may be divided into a small number, Two or more more actuators 114 should be provided in each seat plate for stable support.

At this time, the lower portion of the seat plate 111 and the upper portion of the actuator 114 are coupled to each other through a hinge or the like to adjust the angle so that the height of one actuator is adjusted, So that a rigid coupling state is maintained even when the seat plate 111 inclines.

When the seat panel 111 is divided into two parts as shown in FIG. 1, the seat panel 111 is formed with only a right and left inclination. Therefore, a two-directional hinge having a shaft may be used. However, The slope of the slope can be controlled in all directions. As a representative example, a spherical protruding structure may be formed on the upper end of the actuator, and a structure may be formed to cover the upper end of the actuator in the lower portion of the seat to a certain extent, so that the forward tilt can be adjusted within a predetermined range.

In addition, in the preferred embodiment of the present invention, the respective seat plates 111 are connected to the adjacent seat plates through the elastic members 112. The elastic member 112 is made of a relatively elastic material such as rubber or synthetic fiber having an elastic structure. When a height difference is generated between two adjacent seat panels 111, a step is formed in the adjacent portion of the seat panel, Thereby preventing the user from feeling that he / she is feeling and helping the user to tilt the softer seat 111.
