ABSTRACT:
In a method of folding an inflatable vehicle occupant protection device (14), such as an air bag, the protection device (14) is initially placed in a square configuration. The square configuration is bounded by four side edges (60,62,64,66) of a square panel layer (56) which overlies an inlet opening (46) in the protection device (14). Next, four corner portions (90) of the protection device (14) are pivoted inward about four corresponding fold lines (80,82,84,86). This places the protection device (14) in a smaller square configuration which is bounded by the four fold lines (80-86). The pivoting step is repeated to place the protection device (14) in a successively smaller square configuration each time that step is repeated.
