Abstract

PURPOSE: To provide a supine health chair which can balance the front and rear of the body with respect to the waist when lying on the back and is simple and easy to use by pivotally supporting the middle of each armrest against the upper end of a support frame so that it is free to recline, pivotally supporting a backrest so that it freely flips up and down, pivotally supporting the lower end of the backrest against the rear end of a seat, and providing armrest stoppers at the upper ends of the support frame. CONSTITUTION: When a user sits on a seat 5 and leans has upper body backward while holding armrests 3, 3 in both hands, a backrest 6 leans backward and at the same time the seat 5 is pushed forward and leans backward. Therefore, the waist is supported between the rear of the seat 5 and the front of the backrest 6, i.e., below the pivot pin 14 of the armrests 3, 3, and the armrests 3, 3 also lean backward around the pin 14 and can support both arms of the user. In that condition, the chair is locked by a backward-lean stopper 8', so that the shift to a supine position can be achieved safely and comfortably by simply leaning the upper body backward. Further, when the upper body is raised with the armrests 3, 3 held in both hands, the backrest 6 stands up to its original state and at the same time the armrests 3, 3 and the seat 5 are also returned to their original positions, and this condition is supported by a horizontal position stopper 8 and stabilized, so that the chair can easily be restored to a working position.
