PURPOSE: A headrest interlocking type back extension unit is provided to maximize convenience of a seating posture for a passenger by interlocking the movement of a headrest with a back extension extending a length of a seatback. CONSTITUTION: A headrest interlocking type back extension unit comprises a headrest module (10), a power module (20), and a guide assembly. The headrest module is connected to a seatback frame (2) of a seatback (1) and comprises a cushion pad (11) exposed from the seatback. The power module generates power for the extension of the seatback. The guide assembly interlocks the movement of the headrest module and the power module. The guide assembly lifts an upper part (1a) of the seatback by using the power of the power module and stably guides the movement of the headrest module. [Reference numerals] (AA) Control signal |
