Document Type and Number:
WIPO Patent Application WO/2022/108224
Kind Code:
A1
Abstract:
The present invention relates to a neck retractor, in which, by configuring an air cell with a two-stage structure that can be expanded sequentially, the trapezius muscle is firstly pressed and retracted, and then the cervical vertebrae portion is secondly pressed and retracted, thereby more effectively correcting turtle neck syndrome and further improving the stretching effect of the cervical vertebrae. The neck retractor according to the present invention may comprise: a body part; a first air cell which is installed in the body part and is expanded by air injected from the outside; and a second air cell which is in communication with the first air cell and is stacked-installed on the upper side of the first air cell, and has a smaller cross-sectional area than the first air cell, and thus expands after the first air cell expands, and presses the back of a subject's neck.
