ABSTRACT:
A method of fabricating a gas bag for a vehicular occupant restraint system, the gas bag having an inner side and an outer side and being formed by fabric portions having margins which overlap each other, comprises a first step in which a seam is formed along a substantial portion of the margins at the inner side of the gas bag or between the inner side and the outer side thereof. The method further comprises a second step in which the remaining portion of the margins is closed by a seam formed only from the outer side. A gas bag which can be formed by means of the method described above, has an inner side and an outer side and is formed by fabric portions having margins which overlap each other. The margins are connected to each other by means of a seam. The margins have a first part which, when the gas bag is deployed, faces a vehicle occupant, and a second part corresponding to the remainder of the margins. The seam is formed from the inner side or between the inner side and the outer side of the gas bag in the first part of the margins, and from the outer side in the second part of the margins.
