Abstract:
1. An occupant protection device comprising: a seat belt for restraining an occupant; an adjusting device that relatively adjusts a positional relationship between the seat belt and the occupant; a collision predicting portion that predicts a collision; a control portion that controls the adjusting device when the collision is predicted by the collision predicting portion; a collision detecting portion that detects the collision; and an adjustment amount detecting portion that detects an adjustment amount of the adjusting device, wherein the control portion first makes the adjusting device to operate at a first speed to restrain the occupant by the seat belt, and then makes the adjusting device to increase a distance between the seat belt and the occupant at a second speed that is slower than the first speed, and wherein the control portion first makes the adjusting device to operate at the first speed when the collision is predicted, and then makes the adjusting device to operate at the second speed until a predetermined adjustment amount is detected by the adjustment amount detecting portion when the collision is detected by the collision detecting portion, a movement with the second speed is directed to increasing a distance between the seat belt and the occupant by adjusting a reclining angle of a seatback.
