<P>PROBLEM TO BE SOLVED: To provide an occupant protection device capable of protecting occupant at a rebound time in optimal timing, and easily applied even to a seat belt having pretensioner function and a force limiter function. <P>SOLUTION: In this occupant protection device, a control unit inflates a seat airbag (S111), by generating gas by outputting a signal of seat airbag operation to an inflator in a seat, when the extraction length Lvf of the seat belt exceeds a threshold value CAB (S110, YES), by comparing the length Lvf with the preset threshold value CAB, by extracting the seat belt extracted by operating the force limiter function after the pretensioiner function completes operation. <P>COPYRIGHT: (C)2011,JPO&INPIT |
