  • Patent number: 6082761
    Abstract: A side air bag device has an air bag and a substantially cylindrical inflator for supplying inflation gas to the air bag. The air bag includes a cloth bag and is installed in a vehicle interior in a folded state along the edge of a door opening. The air bag deploys so as to cover the door opening when it inflates. The air bag has a substantially cylindrical tubular gas inflow portion. This gas inflow portion is connected to the inflator so that it covers the inflator. The gas inflow portion is clamped to the outer circumferential surface of the inflator. With a side air bag device according to the invention it is not necessary to use a long pipe that from the inflator and it is possible to increase the freedom of installation of the device and also reduce its weight and cost.

  • Patent number: 6003939
    Abstract: In a seat structure having a side air bag device, a longitudinal groove (36) is formed in a seat back pad (14) along the longitudinal direction of the seat back pad, and an insert wire (40) which holds a seat outer cover, is embedded in the longitudinal groove (36). Bent portions (44) are formed in portions of the insert wire (40), which portions oppose the air bag device. Each of the bent portions (44) is bent in a substantially U-shaped configuration, and a slab pad (46) is wound around an outer peripheral portion of a base portion (44A) of each bent portion. Further, the bent portions (44) of the insert wire (40) are each provided to extend rearwardly and diagonally toward the inner side of a seat back (10) so that the embedded length of the insert wire (40) embedded in the seat back pad (14) is made longer, and adverse influences on riding comfort are thereby suppressed.
