strips 30 the top strip 32 and the bottom strip 34 are fabricated from airbag material known to one skilled in the art for example the material may be a woven nylon fabric a volume of the airbag 28 is a function of in part a quantity of intermediate strips 30 between the top strip 32 and the bottom strip 34 the greater the quantity of the intermediate strips 30 the greater the volume of the airbag 28 the width of each strip 30 is generally determined by the width of the webbing 16 which may also affect the volume of the airbag 28 the intermediate strips 30 may all be the same size or vary in size the intermediate strips 30 are welded together in accordance with a weld pattern in the weld pattern a first edge 38 of a first strip 36 is edge joint welded to a first edge 42 of a second strip 44 a second edge 40 of the first strip 36 is edge joint welded to a second edge 46 of a third strip 48 the second strip 44 and the third strip 48 are on opposite sides of the first strip 36 neither the first edge 38 nor the second edge 40 of the first strip 36 are welded to both the second strip 44 and the third strip 48 the weld pattern results in the edge joint welds of the intermediate strips 30 being staggered between the first and second edges the airbag 28 may be assembled by sequentially stacking and edge joint welding adjacent strips alternatively the airbag 28 may be assembled by stacking all the strips and.
