Airbag structure
First Claim
1. An airbag cushion comprising in part a front panel and a rear panel, wherein each of said front and rear panels has a substantially rectangular or square configuration, wherein each of said panels comprises generally perpendicularly arranged sets of yarns, wherein the yarns in the front panel are at a bias to the yarns in the rear panel, and further comprising a peripheral side panel connected to and extending between peripheries of said front and rear panels, further wherein said front and rear panels have concave sides.

Abstract
An airbag construction for a vehicle is described. The construction utilizes non-circular polygon shaped panels, which provide greater nesting efficiency than previously achieved by comparable airbags using round panels. In addition, the construction enables the airbag to take full advantage of the strength of the yarns forming the fabric, and the energy absorption of the fabric construction, enabling the use of lower tenacity yarns and/or materials at comparable levels of performance.
