Patent 7267360 was granted and assigned to Hyundai Motor Company on September, 2007 by the United States Patent and Trademark Office.
An air-bag structure includes a tear seam that forms an air-bag door. The tear seam is not broken by shock applied from a passenger room, but the tear seam is easily broken upon expansion of the air-bag to secure smooth and reliable deployment of the air-bag operation and provides a sturdy air-bag structure against the shock from a passenger room.
