Air bag fold and method

摘要

An air bag has a neck portion for containing an inflator and receiving the inflator gas therein. A main body portion extends from the neck portion to an outermost edge. The main body portion is folded about a main fold line intermediate the top and bottom edges to substantially fold the main body portion in half The main body portion is then folded about a plurality of accordion folds working from the outer edge to the neck portion to form a compact stack. The stack may be further folded about a pleat fold line to position the folded stack adjacent the neck portion. The air bag and inflator are then stored in a housing. The air bag fold inhibits the air bag from unfolding about the main fold line until the air bag is fully extended.
