Description of the Related Art A conventional headrest device for a hairdressing and beauty chair is used in which a headrest is placed on the top of an elevating device provided in a chair body, and the elevating rod is locked according to the height of a person to be treated. . Most of the conventional headrest devices have a fixed type headrest provided at the top of the above-mentioned lifting device, and in such a fixed type,
There is a problem in that a chair body needs to be housed by projecting to the upper part of the chair body or having a recessed part in the central upper part of the chair body to store the headrest in a complicated assembly structure and spoil the appearance.

Furthermore, as a headrest device for retracting the headrest to the back of the chair back by rotating the headrest, the application has been filed and published by the Company.
No. 52844 and No. 56-43085 are known. In each case, a rotating shaft is rotatably supported at both ends of a pair of brackets fixed to the back of the backrest, and a headrest is fixed to this rotating shaft. It becomes a substantially straight line, supports the back head of the subject, and performs shaving and the like. When not in use, the lock state is released by pressing the push button on the rotation axis provided on the chair body, and the chair can be rotated. It can be accommodated by rotating it on the back of the backrest. In this state, work such as hair cutting and shampooing.

There are issues. This headrest device is configured so that the headrest is pivotally mounted on the top of an elevating rod that can be raised and lowered, and when in use, the elevating rod is raised and locked in an appropriate position, and the headrest is used by rotating the headrest to the front side. ing. When not in use, the headrest is rotated to the back side and the elevating rod is lowered so that the backrest is accommodated on the backside.

Also in this headrest device, two positions of the headrest are determined when the headrest is in use and when not in use, and the headrest is fixed by locking the pivot shaft of the headrest. Although the turning operation can be easily realized, the position of the headrest cannot be properly attached to the neck due to the height difference of the subject,
In addition, there are many inconvenient aspects such as an accident or dissatisfaction with the subject due to a load on the neck portion or an unstable attachment of the subject's headrest when locking the headrest.

[0007]

As described above, the conventional headrest device for a hairdressing and beauty chair is sufficiently satisfactory not only when the headrest is fixed, but also when the headrest is rotatable. There is nothing that has been done. Jikkō 55-52844 and Jikkō 56 described above.
In the headrest of No. 43085, not only the headrest was exposed when it was housed, which was an obstacle to the operator, but also the original beauty of the chair was spoiled. Also, when trying to accommodate the headrest, it is necessary to further rotate while holding the headrest while pressing the push button provided on the chair body, especially this operation at the hairdressing salon when the hands are full. It was very painful for the worker.

Also, in the headrest device of Japanese Utility Model Laid-Open No. 2-89953, the contents of fixing and locking the accommodation position and the use position of the headrest are disclosed. However, although the rotating operation of the headrest can be easily realized, There are inconveniences such as not being positioned at an appropriate position of the headrest due to the height difference of the practitioner.

In order to solve the above-mentioned problems, in the present invention, when the headrest capable of raising and lowering the chair is used, the headrest is fixed and locked so as not to move easily, so that the subject is not anxious. So that they can be treated with peace of mind. In addition, the position of the headrest can be changed appropriately according to the height difference of the subject, the neck of the subject fits to the headrest, the body is not moved too much forward and backward, and shaving can be performed comfortably. To Further, the headrest can be easily accommodated on the back surface of the back of the chair body, and the accommodation operation of the headrest can be facilitated.
