Abstract
A vehicle seat is provided that includes a seat back frame, a headrest, a pressure receiving member that moves independently from the headrest, and pivoting members that are disposed in at least one of both side portions of the seat back frame, are linked to the pressure receiving member, and move independently from the headrest under a predetermined impact load. The pivoting members are linked via coupling members to a biasing element that biases the pressure receiving member toward the front of the seat back frame. The force that restores the pivoting members into an initial state is greatest during normal seating, and covers a range in which the force decreases when the pivoting members move due to a rear-end collision.
