Abstract
A bag for protecting a head of an automobile passenger is formed of a main path having a gas inlet, and a cushion connected to the main path and having chambers communicating with the main path to be expand as a result of gas entering into the cushion from the main path. The chambers includes an upper chamber extending along a top side in a direction of a line extending from the main path and having one end connected to the main path; a side chamber connected to the other end of the upper chamber and extending downwardly from the top side; a lower chamber extending along the bottom side of the bag and having one end connected to the side chamber; and an intermediate chamber communicating with and disposed between the lower chamber and the upper chamber, and separated from the side chamber. The bag can expand smoothly and the required strength is reduced as a result of preventing localized excess stress.
