Claims

[Scope of utility model registration request]

It consists of a support frame, a seat frame whose front end is supported via a link that can swing back and forth to the front end of the support frame, and a back frame whose lower end is rotatably connected to the rear end of the seat frame. , in a chair in which a position above the connection part with the seat frame in the back frame is pivotally supported at the rear end of the support frame, one end is rotatably connected to either the back frame or the seat frame and the support frame. and the other end is provided with a connecting bar that can be freely locked to a locking pin provided on the other side, and a rotation locus of the connecting point between the connecting bar and the back frame or the seat frame around the pivot point of the back frame. A chair characterized in that the rotational trajectory of the connection point between the connection bar and the back frame or the seat frame, centered on the connection point between the support frame and the connection bar, intersects at two points.
