Abstract

In a head-protecting airbag apparatus where an airbag body inflated in a curtain configuration is mounted in a folded state along a roof side rail across at least a center pillar, the airbag body includes an upper portion folded in a bellows, and a lower portion subjected to one of turning-back performed toward an occupant compartment inner side and rolling-up performed towards the occupant compartment inner side. Accordingly, even when there is a vehicle occupant compartment inner side protrusion such as a slip joint in a vehicle, the airbag body is inflated and expanded so as to cover the vehicle occupant compartment inner side protrusion from the above or ride on the same. As a result, the lower portion of the airbag body is hard to be caught up by the vehicle occupant compartment inner side protrusion, thereby improving a expanding performance of the airbag body.
