Abstract
The methods for folding an airbag cushion into a housing provide for a predetermined deployment trajectory. The airbag cushion is defined by an upper panel and a lower panel. A first portion of the airbag cushion is tucked into a second portion of the airbag cushion such that the upper and lower panels of the first portion are positioned in between the upper and lower panels of the second portion. The tucked portion is folded in towards the housing. First and second halves of the tucked airbag cushion are folded in towards the housing. Finally, the folded first and second halves of the airbag cushion are folded into the housing.
