Side airbag and method of folding
First Claim
1. A method for folding an inflatable cushion of a side airbag device to form a folded inflatable cushion that includes a packet of parallel pleats comprising a first end pleat, a second end pleat and a series of middle pleats disposed therebetween, said method comprising:
- providing a securement end of said inflatable cushion;
creating the first end pleat adjacent to said securement end, said first end pleat and said securement end defining one side of the folded inflatable cushion;
creating a traversing portion extending from said first end pleat, said traversing portion defining another side of the folded inflatable cushion;
creating the second end pleat extending from the traversing portion such that the first end pleat and the second end pleat are spaced apart by the traversing portion;
creating said middle pleats extending from the second end pleat towards the first end pleat;
said middle pleats including a final middle pleat adjacent to the first end pleatpositioning an end portion extending from the final middle pleat toward the second end pleat opposite the traversing portion and disposed about the second end pleat, said end portion defining another two sides of the folded inflatable cushion, wherein said end portion is the first portion of said inflatable cushion to deploy when the inflatable cushion is inflated.

Abstract
A method and apparatus for providing a side airbag device for use in a vehicle, comprising: an inflatable cushion for deployment from an unexpanded state to an expanded state. The inflatable cushion is positioned behind a headliner of the vehicle in an un-inflated state and the inflatable cushion is configured to traverse a side of the vehicle when it is inflated. The inflatable cushion also comprising a deploying edge that defines a portion of a periphery of the inflated cushion, wherein the inflatable cushion is folded in a manner that causes the deploying edge to deploy as a first leading edge as said inflatable cushion is inflated to an expanded state by an inflator wherein the deploying edge is the first portion of the inflatable cushion to expand around the headliner.

8. A method for folding an inflatable cushion of a side airbag device to form a folded inflatable cushion that includes a packet of parallel pleats comprising a first end pleat, a second end pleat and a series of middle pleats disposed therebetween, said method comprising;
-
providing a securement end of said inflatable cushion; creating a traversing portion of said inflatable cushion from said securement end, said traversing portion defining a side of the folded inflatable cushion; creating the first end pleat extending from the traversing portion apart from the securement end; creating said middle pleats extending from the first end pleat back towards said securement end; creating the second end pleat extending from the middle pleats adjacent to the securement end; positioning an end portion of said portion of said inflatable cushion extending from the second end pleat about the middle pleats opposite the traversing portions and disposed about the first end pleat, said end portion defining two sides of the folded inflatable cushion, wherein said end portion is the first portion of said inflatable cushion to deploy when the inflatable cushion is inflated. - View Dependent Claims (9, 10, 11)
