ABSTRACT:
A gas column type air bag system of the type in which an air bag includes a main gas column with a relatively large volume when inflated and a plurality of auxiliary gas columns with a relatively small volume when inflated, branched from the main column and extended toward a passenger, thereby rapidly expanding the air bag to inflate in case of a collision. The ratios both in volume and length among the air bag and the main and auxiliary gas columns are so selected that the air bag may be almost instantaneously expanded to the full by the inflation of the main and auxiliary columns and may be securely maintained in the desired stable inflated shape. The inflated main column serves as a knee restraining pad. The high pressure gas requirement for inflating the air bag may be considerably reduced as compared with the conventional systems.
