Abstract
An automated system is disclosed for folding vehicle air bags so that a small folded bag profile in a desirable bag deployment pattern results. A machine having a holding fixture for receiving the retainer of an air bag assembly, and a plurality of upright members. A flattened bag with pleated sides is supported above the upright members, and sequentially inserted between the upright members forming undulating folds. The upright members are removed while retaining the undulating folds. The folds are then compressed, sharpening the folds and forming a compact package. The machine also includes an inserter assembly which inserts the folded bag into the retainer.
