Apparatus and methods, and systems relating to flat panel airbag cushions that may be particularly useful in connection with passenger-side airbag systems. Some embodiments may comprise a first panel and a second panel having a larger cross-sectional area than the first panel in an unfolded state. The second panel may comprise a first set of pleats and a second set of pleats configured such that, upon inflation of the airbag cushion, the first set of pleats and the second set of pleats unfold to define a three-dimensional airbag cushion. The second panel may be sewn or otherwise attached to the first panel about a periphery of the two panels.

1. An airbag cushion, comprising: a first panel; anda second panel having a larger cross-sectional area than the first panel in an unfolded state, wherein the second panel is attached to the first panel about a periphery of the first panel, and wherein the second panel comprises: a first set of pleats; anda second set of pleats intersecting the first set of pleats such that, upon inflation of the airbag cushion, the first set of pleats and the second set of pleats unfold to define a three-dimensional airbag cushion. 2. The airbag cushion of claim 1, wherein the first panel is at least substantially lacking in pleats. 3. The airbag cushion of claim 1, wherein the first set of pleats extend from a top portion of the airbag cushion to a lower portion of the airbag cushion. 4. The airbag cushion of claim 3, wherein the second set of pleats extend at least substantially in a horizontal direction between two opposing sides of the airbag cushion. 5. The airbag cushion of claim 1, wherein the first set of pleats extends in a fan-like pattern with a width of each of the first set of pleats expanding from a first end of the first set of pleats to a second end of the first set of pleats such that the airbag cushion, upon inflation, expands to a larger degree towards the second end. 6. The airbag cushion of claim 5, further comprising a third set of pleats, wherein the third set of pleats is positioned to extend from a first side of the airbag cushion, wherein the first set of pleats is positioned to extend from a second side of the airbag cushion opposite from the first side, wherein the third set of pleats extends in a fan-like pattern with a width of each of the third set of pleats expanding from a first end of the third set of pleats to a second end of the third set of pleats such that the airbag cushion, upon inflation, expands to a larger degree towards the second end. 7. The airbag cushion of claim 1, wherein the first set of pleats and the second set of pleats are formed to avoid extending along an entire length of the airbag cushion such that a top portion of the airbag cushion is formed at least substantially free of pleats. 8. The airbag cushion of claim 1, wherein the airbag cushion comprises a passenger-side airbag cushion configured to inflate between a windshield and an instrument panel of a vehicle. 9. The airbag cushion of claim 8, wherein the second set of pleats are configured to allow the airbag cushion to bend around a vehicle instrument panel of a vehicle upon inflation of the airbag cushion. 10. The airbag cushion of claim 9, wherein the second set of pleats comprise horizontal pleats extending from a first side of the second panel to a second side of the second panel opposite from the first side, and wherein the airbag cushion is configured to be positioned within a passenger-side airbag housing of a vehicle such that, upon deployment of the airbag cushion, the second set of pleats unfolds to allow the airbag cushion to bend around the vehicle instrument panel and towards a passenger of the vehicle. 11. A flat panel, passenger-side airbag cushion, comprising: a first panel; anda second panel having a larger cross-sectional area than the first panel in an unfolded state, wherein the second panel is attached to the first panel about a periphery of the first panel, and wherein the second panel comprises: an unfolded region positioned adjacent to an upper edge of the second panel;a first set of vertical pleats extending from a border of the unfolded region towards a lower region of the second panel, wherein the first set of pleats extends in a fan-like pattern with a width of each of the first set of pleats expanding from a first end of the first set of pleats to a second end of the first set of pleats such that the airbag cushion, upon inflation, expands to a larger degree towards the lower region;a second set of horizontal pleats intersecting the first set of pleats from a first side of the second panel to a second side of second panel opposite from the first side such that, upon inflation of the airbag cushion, the first set of pleats and the second set of pleats unfold to define a three-dimensional airbag cushion. 12. The airbag cushion of claim 11, further comprising a third set of vertical pleats extending from a border of the unfolded region towards a lower region of the second panel, wherein the third set of pleats extends in a fan-like pattern with a width of each of the third set of pleats expanding from a first end of the third set of pleats to a second end of the third set of pleats such that the airbag cushion, upon inflation, expands to a larger degree towards the lower region. 13. The airbag cushion of claim 12, wherein the first set of vertical pleats extends from the first side of the second panel towards a center of the second panel, and wherein the third set of vertical pleats extends from the second side of the second panel towards the center of the second panel. 14. A method for manufacturing an airbag cushion, the method comprising the steps of: obtaining a first panel comprising a first profile defined by a periphery of the first panel;obtaining a second panel comprising a second profile defined by a periphery of the second panel, wherein the second panel has a larger profile than the first panel;forming a first set of pleats in the second panel such that the second panel has a reduced profile defined by a periphery of the second panel after formation of the first set of pleats, wherein the first set of pleats is formed such that a lower portion of the second panel expands to a greater degree than an upper portion of the second panel upon unfolding of the first set of pleats during deployment of the airbag cushion; andafter the step of forming a first set of pleats in the second panel, attaching the first panel directly to the second panel about respective peripheries of the first and second panels. 15. The method of claim 14, wherein the reduced profile is at least substantially identical to the first profile such that the periphery of the second panel after forming the first set of pleats in the second panel is at least substantially identical in size and shape to the periphery of the first panel. 16. The method of claim 14, wherein the step of attaching the first panel directly to the second panel comprises sewing the first panel to the second panel. 17. The method of claim 16, wherein the step of sewing the first panel to the second panel further comprises sewing a first tether to a first side of at least one of the first panel and the second panel and sewing a second tether to a second side of at least one of the first panel and the second panel opposite the first side, and wherein the method further comprises coupling the first tether to the second tether. 18. The method of claim 14, further comprising forming a second set of pleats in the second panel, wherein the second set of pleats intersects the first set of pleats. 19. The method of claim 18, further comprising forming a third set of pleats in the second panel, wherein the third set of pleats is positioned on an opposite side of the second panel relative to the first set of pleats, and wherein the second set of pleats intersects both the first set of pleats and the third set of pleats. 20. The method of claim 19, wherein the first set of pleats extends in a fan-like pattern with a width of each of the first set of pleats expanding from a first end of the first set of pleats to a second end of the first set of pleats, and wherein the third set of pleats extends in a fan-like pattern with a width of each of the third set of pleats expanding from a first end of the third set of pleats to a second end of the third set of pleats. 21. The method of claim 14, wherein the first set of pleats extends in a fan-like pattern with a width of each of the first set of pleats expanding from a first end of the first set of pleats to a second end of the first set of pleats.
