Airbag module with inverted seam and folding tab

An airbag module according to various implementations includes an inflatable cushion, a folding tab, and an inflator. The inflatable cushion includes a first panel and a second panel, each of the first and second panels including an inner surface and an outer surface. When the outer surfaces of the first and second panels are coupled together to form an inverted seam, the folding tab is coupled between the respective outer surfaces of the first and second panels. As a result, the inflatable cushion includes an increased strength while maintaining an ease of assembly using current inflatable cushion folding machines.
