1. An airbag device comprising:
- a bag element that includesa bag body that is inflated and deployed using gas supplied to an interior of the bag body, which increases an internal pressure in the bag body, and that has a hole portion through which gas is discharged to an outside of the bag body; and
a tube vent that is formed in a cylindrical shape open at both ends, wherein a proximal end of the tube vent is connected to the bag body along the hole portion and is rolled up from a distal end of the tube vent toward a proximal end of the tube vent, and wherein, the tube vent is unrolled as the bag body inflates and deploys, and the tube vent discharges the gas from the interior the bag body to the outside of the bag body when the distal end extends outside of the bag body.

Abstract
An airbag device includes a bag element. The bag element includes a bag body that has a hole portion; and a tube vent that is formed in a cylindrical shape with both ends open. The tube vent has a proximal end connected to the bag body along the hole portion and is rolled up from a distal end of the tube vent toward a proximal end of the tube vent. The tube vent is unrolled as the bag body is inflated and deployed, and discharges gas from the bag body when the distal end extends outside the bag body.

7. An airbag device comprising:
-
a bag element that includes a bag body that is inflated and deployed using gas supplied to an interior of the bag body, and that has a hole portion through which gas is discharged to an outside of the bag body; and a tube vent that is formed in a cylindrical shape open at both ends, wherein a proximal end of the tube vent is connected to the bag body along the hole portion and is folded from a distal end of the tube vent toward a proximal end of the tube vent, the tube vent is unfolded as the bag body inflates and deploys, and the tube vent discharges the gas from the interior of the bag body to the outside of the bag body when the distal end extends outside of the bag body, and a folded portion of the distal end of the tube vent presses a portion of the folded tube vent located on a radially inward side of the folded portion of the tube vent and located near the proximal end, thereby reducing the diameter of the folded tube where the folded portion of the distal end presses on the folded tube vent. - View Dependent Claims (8, 10, 11, 12)

13. A bag element for an airbag device, comprising:
-
a bag body that is inflated and deployed using gas supplied to an interior of the bag body, and that has a hole portion through which gas is discharged to an outside of the bag body; and a tube vent that is formed in a cylindrical shape open at both ends, wherein a proximal end of the tube vent is connected to the bag body along the hole portion and is rolled up from a distal end of the tube vent toward a proximal end of the tube vent, and wherein, the tube vent is unrolled as the bag body inflates and deploys, and the tube vent discharges the gas from the interior of the bag body to the outside of the bag body when the distal end extends outside of the bag body. - View Dependent Claims (14, 15)
