A reduced thickness vehicle seat is provided with an active headrest, including a transmission assembly for transmitting a load received by a pressure receiving part to the headrest side, and a mechanism for moving the headrest when a rear end collision occurs. The transmission assembly has a lower link movably installed in the lower part of the seat back frame of the vehicle seat and connected to the pressure receiving part; an upper link disposed in the upper part of the seat back frame and movably connected with the headrest; and a connecting link connecting the lower link and the upper link to each other and operating in association with the operation of the lower link. The connecting link has a bent part bent along the lengthwise direction in the direction to separate from the backrest surface of the seat back.
