ABSTRACT:
Even when a headrest is moved, the hair of the patient is supported and the hair is surely prevented from hanging down.
In a treating seat which can be lifted and lowered by a lifting device, stretched portions which are raised obliquely upwardly from shoulder supporting portions which support the shoulders of the patient are integrally formed. A recess into which a headrest for supporting the head of the patient is fitted is formed between the stretched portions. The side portions of the headrest are pivotally supported on opposing portions by pins, and supported by an engaging device in such a manner that the headrest can be angularly displaced. The stretched portions support the hair and prevent the hair from hanging down.
