PROBLEM TO BE SOLVED: To provide a chair in which a seated person can recline with the natural posture maintained in spite of a simple structure.SOLUTION: The chair includes: a seat 10; a backrest 20 which can be inclined, with the rotation center supported integrally with the seat 10; a first guide part 30 which regulates the moving path of a first part of the seat 10; a second guide part 40 which regulates the moving path of a second part on the rear end side from the first part of the seat 10; and a third guide part 50 which regulates the moving path of the lower end part of the backrest. The first and second guide parts 30, 40 guide the first part and the second part so that the seat 10 displaces, while moving backward from the first posture, to the second posture in which the rear end side is inclined by greatly descending from the front end side. The third guide part 50 regulates the inclination angle of the backrest 20 at each position of the seat 10.SELECTED DRAWING: Figure 2 |
