Abstract
A protection bag for an automobile includes an introducing chamber extending along an upper side of the bag, and a plurality of small chambers disposed parallel to each other at a lower side of the introducing chamber. Some of the small chambers have a spiral shape. Gas inlet of the spiral small chamber faces a pass through port. The length of a gas flowing path of the small chamber is greater than the width of the small chamber. The protection bag can avoid outflow of gas from the small chambers and sufficiently absorb the impact on the passenger's head.
