Patent ID: 7722079

Claim:
An airbag cushion, comprising: a deployment portion deployed by an incoming gas and having a pressure control vent hole formed therein; a belt guider attached to the deployment portion and having first vent holes formed therein so that the gas introduced to the deployment portion can be discharged to the outside through the pressure control vent hole when the deployment portion is deployed; and a sliding belt in which a second vent hole corresponding to the first vent holes is formed, wherein the sliding bent is guided into the belt guider and slides between the deployment portion and the belt guider, when the deployment portion is deployed, wherein the sliding belt slides between the deployment portion and the belt guider in such a manner that before the deployment portion is deployed, the sliding belt clogs the first vent holes, when the deployment portion is partially deployed, the second vent hole forms a flow channel together with the first vent holes so that the gas is discharged along the flow channel through the first vent holes, and when the deployment portion is fully deployed, the sliding belt clogs the first vent holes so that the gas is not discharged through the first vent holes, wherein the sliding belt comprises clamping portions at both ends, the clamping portions being attached to the deployment portion so that the sliding belt is fixed to the deployment portion, and the sliding belt has clamping holes formed therein between the clamping portions, wherein the airbag cushion is supported by an airbag cushion retainer having clamping pins, and the sliding belt is disposed in a folded state so that the clamping holes are latched to the clamping pins and fixed thereto before the airbag cushion is deployed.
