PROBLEM TO BE SOLVED: To suitably control an occupant posture when swinging back of a vehicle occurs. SOLUTION: A control part 130 adjusts an angle of a vehicular seat 110 by outputting a control signal and driving an RY axis direction actuator 120. Normally, the control part 130 rotates the vehicular seat 110 so that the force acts to a direction canceling the force the occupant receives by acceleration of the vehicular to the longitudinal direction. Further, the control part 130 predicts the occurrence of the swinging back of the vehicle based on the signal input from a vehicular sensor 170 and an X axis acceleration sensor 180. When swinging back is predicted, the control part 130 rapidly rotates the vehicular seat 110 to an opposite direction before rotating it to the direction returning to a reference angle. After that, the control part 130 slowly rotates the vehicular seat 110 to the direction returning to the reference angle. COPYRIGHT: (C)2009,JPO&INPIT
