Abstract

An airbag, particularly for the knee or head region of a vehicle occupant, has a substantially cylindrical main region. The airbag comprises a substantially cylindrical fabric tube whose lateral ends are stitched after folding the tube into a predetermined pattern having at least two looped segments. The fabric tube can be formed by joining the lateral edge of a rectangular fabric blank.
