Claims

[Scope of utility model registration request]

A chair comprising: a body support part having a seat part and a backrest part; a base part having legs and a suspension part; and an elastic member provided between the body support part and the suspension part. The seat portion has an L-shape when viewed from the side, and an upright portion extending from the rear end of the seat main body to a height corresponding to the waist of the sitter, and the backrest portion extends from the upper end of the upright portion. In contrast, the backrest main body is connected at its lower end so as to be rotatable about the left-right axis of the chair, and the backrest main body is configured to protrude forward from the rotatable joint at a height corresponding to the waist or lower back of the seater. a pair of protrusions provided on both sides of the backrest main body, and the legs support the seat rotatably around the chair's left-right axis and slidably in the front-rear direction. A pair of the suspension supports are provided in the left-right direction of the chair, each having one end fixed to the leg and the other end supporting the tip of the protrusion so as to be rotatable about the axis in the left-right direction of the chair. The elastic member resists the weight of the body support section that causes the backrest section to tilt backward and the seat section to move forward based on the movable support of the leg section and the hanging support, and maintains the upright position and the rest position of the backrest section. A chair, characterized in that the chair is provided between the body support part and the base part so as to maintain the rear position of the seat part.
