Abstract:
1. An occupant protection device comprising: a retraction mechanism for protecting an occupant, the retraction mechanism retracts a seat belt for restraining the occupant; a change mechanism for supplementing an occupant protection function of the retraction mechanism, the change mechanism changes a tensile force applied to the retracted seat belt, the change mechanism having a cam; a first gas generator that generates a gas for actuating the retraction mechanism; a second gas generator that generates a gas for actuating the change mechanism; and a control portion that performs control such that the first gas generator is actuated if a condition for actuating only the first gas generator is fulfilled, and the control portion performs control such that the second gas generator is actuated at a timing that is uninfluential on an actuation state of the retraction mechanism and that is different from a preset timing for actuating the change mechanism; wherein the gas generated by the second gas generator for actuating the change mechanism moves the cam to change the tensile force applied to the retracted seat belt.
