Abstract: An air-bag is disclosed for use in a safety arrangement in a motor vehicle. The air-bag comprises a front panel (2) and a rear panel (11), the two panels being superimposed and attached to one another around their peripheries in order to define an inflatable chamber. The front panel (2) is provided with an aperture (6) within which is secured an additional panel (17) the additional panel (17) having an area greater than the aperture (6) and being configured so as to define a plurality of adjacent substantially wave-shaped projections (26) which extend forwardly from the front panel when the air-bag is inflated.
