The invention relates to a side curtain airbag for motor vehicles, in particular a side curtain bag which provides greater resistance to impact and thereby reduces the distance of travel of the head of a motor vehicle occupant beyond the side window glass during a side impact collision. The airbag comprises a first inflatable portion 101 configured when inflated to cover and be in spaced alignment with side window glass 106 of at least one passenger door. The first inflatable portion may comprise an inner surface and an outer surface 105, where the latter adopts a concave profile with respect to the opposing and inboard surface of the window glass. A vertical height of the outer surface may be less than that of the inner surface, and a tether 102 may be provided. The concave surface may be as a result of pleats (202 figure 2B) in the outer surface. Alternatively the airbag may be spaced from the window glass by means of one or more additional inflatable portion (402 figure 4A).
