Patent ID: 8364351

Claim:
An occupant protection device comprising: a collision prediction part that predicts whether a collision will occur for a host vehicle; a seatback actuator that adjusts a reclining angle of a seatback that is defined as an angle between the seatback and a seat cushion; a seatbelt retracting part that exerts a driving force to retract a seatbelt to restrain the occupant; a reclining angle sensor that detects the seatback reclining angle; and a controller that controls the seatback actuator so that the reclining angle becomes a target reclining angle and that controls the seatbelt retracting part to retract the seatbelt if the collision prediction part determines that the collision will occur, wherein the controller executes a control, so that the driving force of the seatbelt retracting part when the reclining angle of the seatback is decreased is smaller than at least one of the driving force of the seatbelt retracting part in retracting the seatbelt when the reclining angle of the seatback is not changed and the driving force of the seatbelt retracting part when the reclining angle of the seatback is increased.
