The present invention relates to a backrest-mounted turtle neck straightener, and more particularly, a backrest-mounted turtle neck capable of improving turtle neck syndrome and correcting posture (upper body), as well as strengthening neck muscle strength with only a simple motion in a seated state. It's about braces.

With the development of the information technology industry, most modern people spend a long time in a sitting position for the use of various IT devices (smartphones, tablets, etc.), computer work, and office work.

In particular, in the case of office workers who do a lot of work on a computer, there are many neck pains that come from tense muscles due to incorrect sitting posture and work stress, such as unconsciously sitting in a crooked position with the head facing forward. One of the physical symptoms is turtle neck syndrome.

In October 2016, a survey on the subject of ``occupational diseases'' was conducted on 851 office workers on an online job site, and 82.3% answered that they had an occupational disease. As for the types of occupational diseases, turtle neck syndrome was the most common with 64.1%, and as the cause of occupational diseases, excessive stress was 72.3%, and poor posture was 43.4% in order.

Here, turtle neck syndrome is a symptom that occurs when the angle of the cervical vertebrae (頭推, cervical vertebrae / cervical vertebra) is deformed forward, and is recognized as a health risk factor that occurs widely from adolescents to the elderly. The initial symptoms of such turtle neck syndrome are stiff neck and shoulders and aching pain every time the head is bowed down, and if the symptoms become more severe, chronic headache and head tingling are also found.

Meanwhile, for the prevention of turtle neck syndrome, it is recommended to stretch the shoulder joint and maintain a posture that straightens the chest. Professional treatment methods include chuna treatment and chiropractic treatment, and various orthodontic treatment devices such as auxiliary devices have been proposed.

In connection, the Korean Patent Registration No. 10-0876632 discloses an office chair having a posture correction function that induces a seated person to take a correct posture, and the conventional office chair having the posture correction function is used to determine whether or not to be seated. A seating unit provided with a sensor for detecting seating; A backrest portion provided with a sensor for detecting a waist for detecting whether the waist is in close contact with the lower back; A headrest that allows the head to lean back while seated; Armrests that allow you to put your arms on the seat while you are seated and allow you to adjust the height of the upper and lower sides; A body connecting the seating portion, the backrest portion, and the headrest portion into one, but connecting the seating portion, the backrest portion, and the headrest portion so that the seating portion, the backrest portion, and the headrest portion can be simultaneously retracted or returned to the front; An automatic angle adjustment device for forcibly tilting the seating portion, the backrest portion, and the headrest portion back even when the seated person does not tilt the body backward; When the distance between the headrest and the head positioned in front of the headrest is detected by a head detection sensor protruding from the upper side of the headrest part beyond a preset value, the automatic angle adjustment device is used. The seating part, the backrest part, and the headrest part are actuated so that the seating part, the backrest part, and the headrest part bend backward, but in the state that the seated person is seated by the seat detection sensor, if it is detected that the back part is not in close contact with the back part It characterized in that it comprises a; a control unit for controlling the back and the backrest portion and the headrest portion to be reclined.

It has the effect of preventing back problems.

However, as described above, the control unit operates the automatic angle control device so that the seating part, the backrest part, and the headrest part are simultaneously stretched to stretch the entire upper body, and the head to form a C-shaped neck shape, which is important for turtle neck correction. The effect of making the tortoise back tilt is insignificant, so the improvement effect of turtle neck syndrome cannot be expected to a great extent.

Moreover, in addition to the structural problem of not being able to adjust the height of the headrest according to the body shape (height of the seated) of the seated person (user), the seating part, the backrest part, and the headrest part are connected as a single component. There is a problem of lack of compatibility with the chair (technologies cannot be applied).

Eventually, it corrects the posture so that the cervical angle of the neck of the user (seater) in the chair has an ideal curvature, and also improves the turtle neck syndrome with the traction treatment effect according to the cervical traction, but can be easily installed and used in the existing chair. Research and development of neck braces is urgently required.
