Abstract
An air bag module has a cushion size adjusting mechanism mounted for folding a part of a cushion and holding the same in an air bag housing. Thus, the expansion size of the cushion can be adjusted according to the expansion pressure of the inflator because if the expansion pressure of an inflator is large, the cushion is expanded to a full expansion size, thereby improving the performance and reliability. The cushion size adjusting mechanism is mounted to the air bag housing, thereby preventing accidents such as bruises caused when the cushion size adjusting mechanism is exposed to the outside.
