FAR-SIDE AIRBAG APPARATUS

A far-side airbag apparatus (100) includes an airbag (110) and an inflator (121) that discharges inflation gas for deploying and inflating the airbag (110). The airbag (110) is fixed to the seat frame (130) of the backrest (13) of a vehicle seat (10) and is deployed and inflated on the side corresponding to the center of the passenger compartment. The airbag (110) is divided into first to third inflation chambers (110A-110C), and the first inflation chamber (110A) accommodates the inflator (121). The far-side airbag apparatus (100) includes a tension belt (116) having a first end and a second end. The first end of the tension belt (116) is connected to the surface of the airbag (110) at a position that corresponds to a seam (S2), which divides the first inflation chamber (110A) and the second inflation chamber (110B) from each other, and the second end is connected to the seat frame (130).
