Description

{Head rest for Assisting Chair}

The present invention relates to a headrest supporting a chair, and more particularly, to an ergonomic shape and function capable of supporting a user's neck and head comfortably, and the height of the headrest can be adjusted so as to suit individual body shapes of the user The present invention relates to a headrest for a chair assistant which is easy to carry with minimal volume.

Figs. 1 (a) and 1 (b) show the right posture of a person. As shown in Fig. 1 (a), the cervical vertebrae of the human being are erected in a slightly curved shape (C-shaped) when they are in an upright state, and the neck and head are erected in the form of a line, as shown in Fig. .

However, as shown in FIGS. 2 (a) and 2 (b), when sitting on a chair and leaning on a chair and resting and taking a sleep, the cervical portion floats in the air and the muscles supporting the cervical vertebrae relax, The cervical vertebrae tend to be bent and twisted, and the rounded shape of the back of the head makes it difficult to fix the head.

The left and right neck flexion causes the tension of the neck extensor and the slight fracture of the cervical spine. The level of the pain appears when the angle of 15 degrees or more from the center line of the neck exceeds 5 minutes.

In addition, failure to properly adjust the posterior and posterior tilt of the neck and head can cause pain along with neck muscle tension. For this reason, the frontal inclination of the neck should be properly maintained for the neck and head to rest comfortably. If the inclination angle of the neck is located forward of the center line of the body, the pressure of the neck, tension of the neck muscles And 10 minutes later, I feel discomfort and nausea. Particularly when using a bus or an airplane, nausea accompanies it, and it becomes more painful.

In particular, when sitting in a chair of a vehicle and moving a long distance, sitting on a chair, leaning on the head and back, taking a rest and sleeping, there is no ability to support the neck, so when the time passes, This causes an uncomfortable situation in which the throat is bent to the side, and various forms such as the corner of the side seat or the window and the window frame are changed to change the posture. In addition, there is a problem that the head and the neck are pushed to the left and right due to the sudden movement of the vehicle, the curve and the rocking motion, or sudden shocks can cause the neck pain, and the head can be hit by a window or a window frame to wear a bruise.

In order to solve this problem, an auxiliary pillow for supporting the neck and head of a seated person is mounted on a backrest of a chair, or an auxiliary headrest for supporting a neck and a head by wearing on a seated person's neck, It can prevent the neck stress and the sudden movement of the head due to uncomfortable posture, as well as to prevent the accident such as neck fracture and bruise.

However, as shown in FIG. 3, the conventional auxiliary headrest is generally classified into an air-inflated product and a general fiber-reinforced product. In the case of a pneumatic product, although the neck is supported, It is not natural to feel the skin around the neck due to obstruction of the blood stream, and when the human body such as the neck or the like touches the surface of the synthetic resin material, the touch is not good and the use thereof is avoided, and the part supporting the neck and head is ergonomically designed There was a problem that it did not provide comfort.

In addition, the general fiber filler product has a soft feeling but it is not easy to carry because of its bulky shape. This product also does not provide comfort because the neck and head supporting parts are not ergonomically designed, There is a problem that there is a limit in providing comfort.

In addition, the conventional headrest for ancillary use can be stored well at the time of use, but if not used, the headrest can be easily lost because it is left unused for a long time. When the user wants to use the headrest again, There is a problem that it is inconvenient to do, and it is not practical or economical.

In addition, in the prior art, the auxiliary head restraint is merely a basic form of a simple neckrest, and has only a function of supporting the neck, but does not disclose a product that prevents the head from being bent right and left.
