Airbag apparatus for head-protecting
First Claim
1. A head-protecting airbag apparatus comprising an airbag body expanding in a curtain shape is disposed in a folded state along a roof side rail across at least a center pillar, wherein the airbag body is folded such that an upper portion of the airbag body in a state in which the air bag body is attached to a vehicle body projects in a vehicle occupant compartment while pressing out a lower portion of the air bag body before the lower portion of the air bag body in the state in which the air bag body is attached to the vehicle body projects in the vehicle occupant compartment when expanding, wherein the airbag body includes the upper portion which is folded in a bellows shape and the 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.

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.

10. A head-protecting airbag apparatus comprising an airbag body expanding in a curtain shape is disposed in a folded state along a roof side rail across at least a center pillar, wherein the airbag body comprises a gas introducing path formed only on a region positioned below the roof side rail generally linearly along the roof side rail, one end of the gas introducing path communicating with an inflator, and a plurality of inflating chambers formed in only a region positioned below the roof side rail, one end of the inflating chambers communicating with the gas introducing path, and the gas introducing path is one of (1) not folded or (2) folded along the longitudinal direction of the gas introducing path, wherein a portion of the airbag body except for the gas introducing path has a bellows-folded portion and a turned-back portion toward a vehicle compartment inner side formed sequentially and downwardly along a vertical direction.
- 11. A head-protecting airbag apparatus comprising an airbag body expanding in a curtain shape is disposed in a folded state along a roof side rail across at least a center pillar, wherein the airbag body is folded such that an upper portion of the airbag body in a state in which the air bag body is attached to a vehicle body projects in a vehicle occupant compartment while pressing out a lower portion of the air bag body before the lower portion of the air bag body in the state in which the air bag body is attached to the vehicle body projects in the vehicle occupant compartment when expanding, wherein the upper portion of the air bag body is folded in a bellows shape and the lower portion of the airbag body is subjected to turning-back performed toward an occupant compartment inner side.
