Abstract
A method of folding an air bag (10) includes locating the air bag in a first configuration with front and back parts (140, 142) overlying each other and with a side part (70) folded and extending outwardly from the front and back parts. First and second portions (150, 152) of the air bag (10) are on opposite sides of a top to bottom centerline (154). A retainer (114) is located adjacent the top edge (144) of the configuration. The air bag (10) is folded from bottom to top to a second configuration in which it overlies and has a height corresponding to the height of the retainer (114). The first and second portions (150, 152) of the air bag (10) have portions (151, 153) that project laterally beyond the sides (124, 126) of the retainer (114). The laterally projecting portions (151, 153) are moved laterally inward to overlie the retainer (114), and the air bag (10) has a width corresponding to the width of the retainer. The first portion (150) of the air bag (10) as thus folded is a mirror image, about the centerline (154), of the second portion (152).
