Abstract
A head-protection air-bag device includes a head-protection air-bag body that can be mounted in a folded state along a roof side rail, and is deployed like a curtain so as to cover at least a center pillar from the inside of a vehicle compartment. A deployment-direction regulator (e.g., a projecting portion of a center-pillar garnish) that regulates the deployment direction of the head-protection air-bag body toward the inside of the vehicle compartment is provided at a position above and adjacent to an interior projection of the vehicle compartment such as a slip joint at the center pillar. Alternatively, or in addition to the deployment-direction regulator, a lower end of a portion of the air-bag body that covers the center pillar can be shaped so as not to project downward from an inflation chamber, and/or can be provided with a longitudinal inflation chamber at its lower end that inflates during an early stage of inflation and deployment to prevent that portion of the air-bag body from catching on the interior projection of the vehicle compartment.
