Abstract
An air bag cushion for vehicles has a connection part which is formed in front portions of the left and right chambers by sewing the inner surfaces of the left and right chambers along sewing lines in a shape of closed curve to form a vertical valley which separates the left and right chambers from each other. A through hole is formed in the connection part to permit gas to flow between the left and right chambers. The cushion includes a tether which passes through the connection part and connects the left and right chambers to each other in a lateral direction of the cushion. The air bag cushion is simple in structure and is superior in uniform expanding performance of the left and right chambers.
