Patent ID: 7784821

Claim:
A device for decreasing peak pressure of an airbag, the device comprising: an airbag; an airbag cover receiving the airbag therein to protect the airbag; a tear seam formed on the airbag cover and configured to be torn by pressure applied from the airbag; and a pre-compressed member positioned near the tear seam to apply pressure to the tear seam before the airbag is fully inflated, wherein the pre-compressed member includes an inflation tube formed from a pre-compressed elastic material, wherein the pre-compressed member is supplied with a part of a gas provided to the airbag to apply the pressure to the tear seam, wherein the inflation tube that is provided near the tear seam and is connected to an inflator that supplies gas to the airbag by a gas supply tube, wherein the inflation tube is mounted by a fixing film coupled to the airbag cover, and wherein the fixing film supports the inflation tube without being torn during inflation of the inflation tube so that the expansive force of the inflation tube is concentrated on the tear seam while the airbag is deployed.
