Claims

[Scope of utility model registration request]

The movable side frame body is attached to the fixed side frame body fixed to the stay.
The both sides thereof are connected so as to be movable in the front and back direction through parallel link mechanisms, and at least one link of the parallel link mechanism on at least one side is inclined in the axial direction of the non-axial support relative to the fixed side frame body. A block is formed in the stationary side frame and has a retaining pin that is moved horizontally forward and backward by the rotation of the operating rod and that is inserted into and engaged with the elongated hole of the frame, and the operating rod As the block moves forward and backward due to the rotation of the block, the parallel link mechanism is tilted in the front-rear direction, thereby making it possible to adjust the movement of the movable side frame body in the front-rear direction with respect to the fixed side frame body. headrest device.
