The present invention relates to an airbag cushion which simultaneously exhibits a low amount of seam usage (in order to attach at least two fabric panels or portions of a single panel together) as well as a very low amount of fabric utilized to produce the target airbag cushion, both in correlation to an overall high amount of available inflation airspace within the cushion itself. These two separate, but correlated factors, one based on an effective seam usage index are now combined for the first time in what is defined as an effective seam usage index (being the quotient of the length of overall seams on the cushions and the available inflation airspace volume) and the other based on an effective fabric usage index (being the quotient of the amount of fabric utilized in the construciton of the airbag cushion and the available inflation airspace volume). The inventive airbag cushion must possess an effective seam usage factor of at most 0.11 and an effective fabric usage factor of at most 0.0330. A cushion exhibiting such low seam usage and fabric usage factors and also comprising an integrated looped pocket for the disposition of an inflator can is also provided as well as an overall vehicle restraint system comprising the inventive airbag cushion.
