ABSTRACT:
An airbag and a method for making an airbag of the type that includes an irregularly-shaped panel, such as the side panels of a passenger airbag. The irregularly-shaped side panel is first divided into two segments with a single straight line to define an inflation segment and an impact segment. The straight line drawn to define the largest polygon that can be defined by any single straight line without coming too close to the inflation module hole. By segmenting the larger, irregularly shaped panel into two smaller ones with one of those being polygonal, better nesting of the segments can be obtained, which significantly improves fabric utilization to offset the labor cost from sewing the two segments together when making the irregularly shaped side panel required for the airbag.
