Patent ID: 7568542

Claim:
An occupant protection device, comprising: a first motor which retracts a webbing of a driver seat; a second motor which retracts a webbing of a front passenger seat or a rear seat; a brake pedal sensor which detects a pressing amount and a pressing speed of a brake pedal; and a control device which controls the first motor to retract the webbing of the driver seat when a detection value of the brake pedal sensor has exceeded an operation threshold value of the first motor, and controls the second motor to retract the webbing of the front passenger seat or the rear seat when the detection value of the brake pedal sensor has exceeded an operation threshold value of the second motor, wherein, in the control device, the operation threshold value of the second motor is set to be lower than the operation threshold value of the first motor, the operation threshold values of the first and second motors in accordance with the pressing amount of the brake pedal are set to be substantially the same when the pressing speed of the brake pedal is low, and the operation threshold values of the first and second motors in accordance with the pressing amount of the brake pedal are set such that the difference between the operation threshold values becomes larger as the pressing speed of the brake pedal becomes higher.
