Description

Cervical correction device

[0001] The present invention relates to a cervical correction device that pulls the shoulders back and opens the chest to establish a correct posture of the cervical spine by applying a force that pushes the spine (thoracic and lumbar) forward.

[0002] The cervical vertebrae, the neck bones, are shaped to maintain a constant C-shaped curve, supporting the weight of the head and external forces. However, prolonged computer or smartphone use places continuous stress on the cervical vertebrae and surrounding tissues, such as muscles and ligaments, which can lead to deformities in the cervical vertebrae. These symptoms can also occur due to trauma such as traffic accidents.

[0003] In these cases, the cervical spine is often deformed into a misaligned state, such as a straight shape, and patients with a straight cervical spine are often called turtle neck patients. To prevent turtle neck, it is necessary to use a chair or mobile device in the correct posture, but this is often not followed. Once turtle neck occurs, a correction process is necessary, and various devices and equipment for this purpose are known.

[0004] In relation to turtle neck correction, Korean Patent No. 10-1402167 discloses a device characterized by mounting a turtle neck prevention device on the upper part of the backrest of a chair and raising and lowering the turtle neck prevention device in response to changes in the angle of the backrest. However, there is a problem that the scope of use is limited to chairs, making it difficult to apply to chairs that have already been manufactured.

[0005] The present invention has been devised to solve the aforementioned problem, and its purpose is to provide a cervical correction device that can maintain a correct posture in which the chest is naturally expanded and the chin is pulled toward the neck by applying force in opposite directions to the shoulders and spine.

[0006] In addition, the cervical correction device of the present invention aims to pull the jaw by applying pressure to the cervical spine.

[0007] According to one aspect of the present invention for achieving the aforementioned purpose, a shoulder support frame and an airbag part capable of maintaining a straight posture for the back and chest can be provided.

[0008] According to another aspect of the present invention, a spinal correction device including a cervical compression unit that compresses the cervical spine in a correct posture with the back and chest straight can be provided.

[0009] The effects of the cervical correction device according to the present invention are described as follows.

[0010] According to at least one of the embodiments of the present invention, the chin can be pulled toward the neck to maintain a correct posture through a back-pushing pressure band and a shoulder support frame that straightens the shoulders.

[0011] According to at least one of the embodiments of the present invention, by applying concentrated pressure to the cervical spine while the back and shoulders are straight, a pulled chin can be pulled to further maintain a correct posture.

[0012] According to at least one of the embodiments of the present invention, the chin traction unit can be detached from the pressure plate to reduce the volume and facilitate storage.

[0013] Further scope of the applicability of the present invention will become apparent from the detailed description below. Since various modifications and variations within the spirit and scope of the present invention will readily become apparent to those skilled in the art, it should be understood that the detailed description and specific examples, such as preferred embodiments of the present invention, are given by way of illustration only.
