An airbag is disclosed which is made from two superimposed layers (1,12) of flexible material, said layers being substantially polygonal in shape and being secured to one another by a plurality of edge-seams (16). Each edge-seam (16) comprises a lap-joint formed between an edge-region of one of said layers (12) and a respective edge-flap (14) of the other layer (1) folded over said edge-region. The airbag is configured such that adjacent edge-flaps (14) do not overlap with one another, thereby minimising the thickness of said flexible material in the region of each corner (17) of the polygonal bag.
