Abstract
A curtain airbag capable of preventing a partial decrease in internal pressure to improve ejection prevention performance. The airbag includes: a main chamber, which inflates first; a delay chamber that is inflated with gas from the main chamber; a linear seam portion where front and back base fabrics are joined to partition the main chamber from the delay chamber; a planar seam portion formed at a lower end of the linear seam portion to define a non-inflation region in a range of the front and back base fabrics; and a gas inflow channel provided between the planar seam portion and the lower edge of the airbag to allow gas to flow from the main chamber into the delay chamber. The front and back base fabrics of the gas inflow channel sag upon completion of inflation and deployment to form a wrinkled portion that blocks or narrows the gas inflow channel.
