<p>The passenger protection device is capable of implementing thorough passenger protection at low costs. This passenger protection device comprises an airbag 150 having a protection space portion region 153 for alleviating restraint pressure at the time of restraining a passenger at the middle region thereof when expanding and inflating, so as to restrain the passenger regardless of differences in physical shape of the passenger on the vehicle seat S at the time of expansion and inflation. Determination is made regarding whether or not a directly seated object on the vehicle seat S is a passenger 10 or a child seat 12, based on the tension information from a belt tension sensor 114 sensor. In the event that determination is made that the directly seated object is a passenger 10, an inflator 140 is controlled such that the protection space portion 153 of the airbag 150 expands and inflates with a restraining pressure alleviated as to the passenger 10, while in the event that determination is made that the directly seated object is a child seat 12, the inflator 140 is controlled so as to suppress effects of the retaining pressure of the airbag 150 as to the passenger in the child seat 12 (Fig. 1).</p> |
