This paper discusses parametric optimization of the cushion shape of passenger side airbag, which has three-dimensional and vehicle interior parts dependent shape and how it is very important to define the design variables to make the ranges of variables, and to set up the design process. In this paper, the considerations of cushion design of mid-mounted passenger airbag are presented. Considered design variables are size, width of cushion, location, width, the number of tether, and size of vent hole. By using orthogonal array, in-position NCAP simulation is performed within the ranges of given control levels. Also, the relationships among design variables are analyzed to help the design of airbag cushion.
