Method of folding an airbag for a vehicle safety restraint

A method of folding an airbag for insertion in an airbag housing in a vehicle comprising the steps of:

• laying the airbag generally flat;
• making folds in the flat airbag to form a polygon in plan view, the polygon having a geometric centre, a plurality of corners and a plurality of sides, the plurality of corners being equal to the plurality of sides, the method further comprising:
• folding each of the plurality of sides of the polygon upwardly and inwardly of the polygon considered in plan view so at least one point on each of the plurality of sides meets a point on at least one other of the plurality of sides at a position generally above the centre of the polygon so that each of the plurality of corners of the polygon form a respective upstanding corner ear, and subsequently:
• rolling the upstanding corner ears of the polygon to flatten them against the sides of the polygon and to form the airbag into a cylindrical shape.
