A vehicle seat (car seat (S)) includes a seat cushion (S1), a seat back (S2), and a headrest (S3), the seat back (S2) including a seat back frame constituting a frame of the seat back (S2), and a seat back pad covering the seat back frame, and the vehicle seat being configured to allow an upper body of an occupant to sink into the seat back (S2) when a backward movement load acts on the seat back from the occupant's upper body. The seat back pad includes a center portion (51) configured to face a back region of the occupant's upper body, and right and left side portions (52) provided at right and left sides of the center portion (51) and each configured to protrude frontward farther than the center portion (51), and each of the right and left side portions has an upper side portion (52A) corresponding to a height of a chest region of the occupant and a lower side portion (52B) corresponding to a height of a lumbar region of the occupant, which are configured such that when they receive the backward movement load, the upper side portion (52A) is more easily deformable than the lower side portion (52B). |
