An air bag and method of folding same, the air bag including material defining a top, front, and bottom portions and side panels and an open inlet end, comprising the steps of: securing the inlet end about a retainer, positioning the material so that is lays relatively flat with the top or bottom portion laid upon the folding surface, with the retainer slightly above the surface and with a first portion of the air bag extending to the right of the first end, a second portion extending to the left of the second end of the retainer a middle portion therebetween, folding over the first portion inwardly, toward a second fold line, about a first fold line defining a first folded over portion; folding over the first folded over portion outwardly toward the first fold line about the second fold line, continuing folding the first portion about the first and second fold lines, repeating the above steps to fold the second portion of the air bag, positioning the folded over portions resulting from the folding of the first and second portions of the air bag parallel to one another, and then forming a plurality of pleats and folds forming a pleated end and placing the pleated end adjacent the retainer. Folding material extending from the pleated end against the pleated end and securing the air bag in its folded configuration.

A method of folding an air bag (30), the air bag including material defining a top (32), front (34), and bottom (36) portions and side panels (38a,b) and an open inlet end (48), comprising the steps of: a) securing the inlet end about a retainer (44), the retainer having a determinable length, diame
A method of folding an air bag (30), the air bag including material defining a top (32), front (34), and bottom (36) portions and side panels (38a,b) and an open inlet end (48), comprising the steps of: a) securing the inlet end about a retainer (44), the retainer having a determinable length, diameter, and first and second ends; b) positioning the retainer (44) relative to a folding surface; c) defining a line in the material to be laid on the folding surface such line determining a tip end (70); d) positioning the material so with one of the top portion (32) and bottom portion (36) laid upon the folding surface and with a first portion (92) of the air bag extending to the right of the first end, a second portion (94) extending to the left of the second end of the retainer a middle portion therebetween e) forming in the material a plurality of axially extending pleats and tucks (74, 72) each pleat (74) having an end laid relatively colinear to the tip end (70) to reduce the length of the material extending outward from the retainer; f) defining in the air bag first, second and third parallel fold lines (84, 86, 90) which extend perpendicular to a longitudinal axis (80) of the retainer, the second fold line situated between the first and third fold lines, the distance between the first and third fold lines defining a desired width of the folded air bag; g) folding over the first portion inwardly, toward the second fold line, about the first fold line defining a first folded over portion; h) folding over the first folded over portion outwardly toward the first fold line about the second fold line; i) continuing folding the first portion at the first and second fold lines until the there is no longer enough material to be folded over either the first or the third any fold line; j) folding over the second portion inwardly, toward the second fold line, about the third fold line defining a second folded over portion; k) folding over the second folded over portion outwardly toward the third fold line at the second fold line; l) continuing folding the second portion about the third and second fold lines until the there is no longer enough material to be folded over any fold line; m) positioning the folded over portions (92′, 94′) resulting from the folding of the first and second portions of the air bag parallel to one another, the material of the air bag in the folded over configuration farthest from the retainer defining a pleated end (75).
