Patent ID: 7487997

Claim:
An air-bag being formed from an element of laminar material, the element of laminar material defining a central polygonal region having at least four side edges, and the element of laminar material having a shape and configuration equivalent to that of the air-bag when inflated, the side edges of the central polygonal region each carrying a protruding flap to define a plurality of protruding flaps including an upper flap and a lower flap and at least two side flaps, the upper and lower flaps having a combined area which is greater than an area of the central polygonal region, there being at least one infill element defined between at least one of the side flaps and at least one of the upper and lower flaps, the side flaps and the upper and lower flaps being inwardly folded to overlie the central polygonal region and to at least partially overlie each other, the infill element lying between two respective inwardly folded adjacent flaps defined by one of the side flaps and one of the upper and lower flaps, the protruding flaps being secured to form the air-bag.
