A vehicle occupant protection device that smoothly operates a seat and a seatbelt. When a collision is predicted, if the time to the collision reaches a preset time t1, a seat control ECU starts operation of a seat actuator, and if a time to the collision reaches a preset time t2 (t1>t2), the seat control ECU starts operation of a seatbelt actuator. Further, when the time t2 to the collision is reached or when the time t3 (t1>t2>t3) is reached at which time the seatbelt actuator is activated to start application of a predetermined tensile force to the seatbelt, the seat control ECU stops operation of the seatbelt actuator. Seat adjustment and seatbelt adjustment may be adapted such that both the adjustments are not performed at the same time or, alternatively, such that both the adjustments are operated at the same time only during a time period in which application of the predetermined tensile force to the seatbelt starts. |
