Curtain airbag

An airbag for protecting a vehicle occupant. The airbag (100) includes an inner panel (110) and an outer panel (120) connected to form an inflatable chamber. The airbag includes a cloth sealing element (200) connecting the periphery of the inner and outer panels; wherein the sealing element is located both inside and outside of the inflatable chamber; and wherein certain yams from the sealing element are located entirely within the inflatable chamber. The airbag may include a cloth connecting element connected to the inner and outer panels at a position away from the periphery of the panels to thereby form a non-inflatable region (170) located within the inflatable chamber.
