VEHICLE SEAT

A vehicle seat includes a driving portion capable of changing a position of a seat (34, 72), a rear-seat airbag (48) that is fixed to the seat and deploys between a seatback portion (42) of the seat and an occupant seating space of a rear seat behind the seat, and a control portion configured to change the position of the seat with the driving portion, and adjust a deployment region of the rear-seat airbag, when a collision of a vehicle is predicted.
