Abstract
A medical chair has a cranium position regulating device and a pelvis-and-knee position regulating device for respectively regulating the positions of the cranium and pelvis of a subject who sits on a seat. The cranium position regulating device and the pelvis-and-knee position regulating device have structures in which they butt against both right and left sides of the cranium and the pelvis, respectively, to cause both planes centered in a right-and-left direction of the cranium and the pelvis to be in a same central plane which extends in the direction of gravity. An ideal condition of the body of the subject in which vertical and horizontal balances are achieved against the force of gravity can be achieved to ensure physiological curvature of vertebrae and the condition can be maintained.
Claims10
A medical chair which is mainly useful for maintaining a relaxed condition of muscular tension of a human body in a condition where physiological curvature of individual vertebrae is realized and human body extends along a direction of gravity, and characterized in that
- said chair comprises cranium position regulating means and pelvis-and-knee position regulating means for respectively regulating a position of a cranium and a position of a pelvis of a subject who sits on a seat, and said cranium position regulating means and said pelvis-and-knee position regulating means butt against both right and left sides of the cranium and the pelvis, respectively to cause both planes centered in a right-and-left direction of the cranium and the pelvis to be in a same central plane which extends in the direction of gravity, said pelvis-and-knee position regulating means further including knee butting means for butting against the outside of the knees of the subject in a seated condition to cause an angle formed by the knees to be bilaterally symmetrical about the central plane, thereby fixing positions of the knees.
