Claims

[Scope of utility model registration request]

A pillar having a notch for height adjustment on one side and a notch for regulating lower limit movement on the other side, a support tube fixed to the seat bag and inserted through the pillar of the headrest, and a flange on the upper edge of the support tube. an operating knob attached to the fixed part so as to be slidable in a direction orthogonal to the axial direction of the pillar; a first knob connected to the operating knob and provided in the fixed part so as to be freely retractable into and out of a recessed part for adjusting the height of the pillar; A second locking pin and a second hole provided in the fixed part so as to be able to move in and out of the notch for regulating the lower limit movement of the pillar.
A headrest vertical adjustment device consisting of a lock pin and a spring that biases the first and second lock pins toward the pillars and biases the operating knob in the opposite direction.
