AIRBAG, AIRBAG DEVICE, AND METHOD FOR SEWING LID MEMBER OF AIRBAG
First Claim
1. An airbag comprising:
- a vent hole for releasing gas supplied in the airbag; and
a lid member for making the vent hole openable and closable;
wherein a seam formed by sewing the lid member to the airbag is disposed in a sewing region defined by a straight line shape spaced a predetermined distance from the vent hole, and a curved shape formed by bringing both ends of the straight line shape close to a center line of the vent hole parallel to the straight line shape, andwherein a curvature of the seam can be regulated in view of lap width between the lid member and an outer edge of the vent hole.

Abstract
Provided are an airbag, an airbag device, and a method for sewing a lid member of an airbag that can make it easier to maintain the internal pressure until inflation and deployment of the airbag are completed and to quickly release gas after an occupant contacts the airbag. An airbag includes a vent hole for releasing gas supplied in the airbag, a lid member for making the vent hole openable and closable, and a tether for applying tension to the lid member. A seam formed by sewing the lid member to the airbag is disposed in a sewing region defined by a straight line shape spaced a predetermined distance from the vent hole, and a curved shape (most curved shape) formed by bringing both ends of the straight line shape close to a center line of the vent hole parallel to the straight line shape. The curvature of the seam can be regulated in view of the lap width between the lid member and the outer edge of the vent hole.
