VEHICLE SEAT

Provided is a vehicle seat that, using a simple configuration that is independent from a headrest, is capable of increasing the amount of sinking (movement) of the body of a seated occupant toward a seat back at the time of a rear-end collision, and is capable of effectively reducing the impact on the occupant at the time of a rear-end collision. A vehicle seat S includes a seat back frame 1, a headrest S3, a pressure receiving member 20 that moves independently from the headrest S3, and pivoting members 30 that are disposed in at least one of both side portions of the seat back frame 1, are linked to the pressure receiving member 20, and can move independently from the headrest S3 under a predetermined impact load. The pivoting members 30 are linked via coupling members 21 and 22 to a biasing means 35 that biases the pressure receiving member 20 toward the front of the seat back frame 1. The force that restores the pivoting members 30 into an initial state is greatest during normal seating, and covers a range in which the force decreases when the pivoting members 30 move due to a rear-end collision.
