Airbag structure
First Claim
1. An airbag cushion comprising a front panel and a rear panel, wherein each of said front and rear panels has a non-circular configuration, wherein each of said panels comprises generally perpendicularly arranged sets of yarns, and wherein the yarns in the front panel are at a bias to the yarns in the rear panel.

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.

- 1. An airbag cushion comprising a front panel and a rear panel, wherein each of said front and rear panels has a non-circular configuration, wherein each of said panels comprises generally perpendicularly arranged sets of yarns, and wherein the yarns in the front panel are at a bias to the yarns in the rear panel.
- 7. An airbag cushion comprising a front panel and a rear panel, wherein each of said panels has a polygonal configuration with a maximum of four sides, wherein each of said panels is formed of at least two generally perpendicularly arranged sets of yarns, and wherein the yarns in the front panel are at a bias to the yarns in the rear panel.
- 12. An airbag cushion comprising a front panel and a rear panel, wherein each of said front and rear panels has a geometrical configuration approximating a square, a rectangle, or a triangle, wherein said panels comprise generally perpendicularly intersecting warp and filling yarns, and wherein the yarns in the front panel are at a bias to the yarns in the rear panel.

19. A method of making an airbag comprising the steps of:
-
providing first and second fabric panels having a non-circular geometrical configuration, orienting the panels such that at least one yarn in one of the panels is at a bias to at least one yarn in the other panel, and securing the panels to form an airbag. - View Dependent Claims (20, 21, 22)
