A gas bag for a vehicular occupant restraint system comprises two plies of fabric partially interwoven along their outer edges. To offer protection over a lengthy period in time amounting to several seconds but nevertheless dissipate the energy of impact to the required degree on impact and cushioning of the occupant, the plies of fabric are substantially air-tight, and the volume of the gas bag is divided by partial interweaving of the plies of fabric within the outer edges into several chambers. Further, the chambers are interconnected by at least one choked port remaining between the portions of the interwoven plies of fabric. Only part of the chambers is directly inflated by an inflator, the remaining part of the chambers being indirectly inflated via the choked port.
