folding the second bottom longitudinal edge toward the first top longitudinal edge wherein a second bottom fold is formed about one-half to one-fifth of the width of the first bottom fold;
folding the second bottom fold toward the first top longitudinal edge thereby forming a first plurality of folds extending to about one-eighth to one-fifth of the width of the airbag from the first top longitudinal edge, wherein the first plurality of folds comprises a backside downwardly oriented;
orienting the back portion of the folded airbag upwardly and the front portion downwardly;
