Abstract: An occupant protection system for protecting a vehicle occupant sitting in a seat includes a seatbelt that includes a lap belt for arresting the pelvis of the occupant, and an airbag disposed in the lap belt. The airbag is coupled to the lap belt in such a manner as to be movable relative to the lap belt in a left and right direction, and includes a main inflatable portion that is deployable in front of upper body of the occupant, and a positioning inflatable portion that protrudes from a lower end region of the main inflatable portion. The positioning inflatable portion includes a contact surface that contacts and is supported by an environmental member which is disposed in a circumference of the lap belt at airbag deployment, whereby helps align a center in the left and right direction of the main inflatable portion generally with that of the upper body.

Abstract: A side airbag device includes a main bag which is an airbag deployed between a passenger seated on a seat and a side wall portion of a vehicle. The airbag expands by gas supply when a vehicle side collision occurs. The side airbag device also includes a sub bag deployed between a side frame on a vehicle outer side in a seat back of the seat and the passenger. The sub bag expands by supplying gas and pushes a waist portion of the passenger forward from backward, prior to deployment of the main bag, when the vehicle side collision occurs.

Abstract: An airbag is inflatable in such a manner as to separate a vehicle-side wall which is deployable towards a vehicle body structure and an occupant-side wall which is deployable towards an occupant for catching the occupant. The airbag is configured to be supported by the vehicle body structure on the vehicle-side wall when catching the occupant with the occupant-side wall. The airbag includes a recessed section on left and right sides of and in a vicinity of the center of the occupant-side wall and a tether that connects the bottom of the recessed section to the vehicle-side wall in order to form the recessed section. Opposing walls of the recessed section press each other in a separable fashion when the airbag is inflated. The tether allows gas communication between a central region of the airbag and a peripheral region of the airbag which surrounds the central region, inside the airbag.

Abstract: An airbag includes a high pressure expansion chamber, a low pressure expansion chamber, and a communication passage, which connects the high pressure expansion chamber and the low pressure expansion chamber to each other. A gas supply port, which supplies inflation gas into the airbag, is located inside the low pressure expansion chamber to discharge the inflation gas toward the inside of the communication passage. The communication passage extends from the edge of a communication port, which connects the high pressure expansion chamber and the low pressure expansion chamber, toward the inside of the high pressure expansion chamber. At deployment and inflation of the airbag, the communication passage is located between a seam formed at the outer periphery of the base fabric sheet of the airbag and the gas supply port.

Abstract: Inside of an airbag is partitioned by a partitioning member into an upstream inflation portion, which is inflated by a supply of gas, and a downstream inflation portion, which is inflated by inflow of the gas from the upstream inflation portion. The partitioning member includes a wide portion where an external force to be applied accompanying an occupant restraint by the airbag becomes largest. In the partitioning member, slits are formed at portions other than the wide portion. The slits cause the gas to flow into the downstream inflation portion from the upstream inflation portion upon the inflation of the airbag. The slits are opened by the force to increase the flow rate of the gas into the downstream inflation portion from the upstream inflation portion during the occupant restraint by the airbag compared to the gas flow rate before the occupant restraint by the airbag.

Abstract: A lateral partition is formed by a pair of structural fabric portions, each of which has a first peripheral portion and a second peripheral portion. The first peripheral portions of the structural fabric portions are each joined to one of main body fabric portions. The second peripheral portions of the structural fabric portions are joined to each other by a joint portion provided along the second peripheral portions. An inner tube extends over the upper inflation chamber and the lower inflation chamber, while intersecting with the lateral partition. A rear peripheral portion of a part of the inner tube is joined to the main body fabric portions by a part of the peripheral joint portion, and a front peripheral portion of the part is joined to the structural fabric portions by the joint portion.

Abstract: An airbag includes an airbag body and an inner tube. The inner tube includes a gas upstream section located in an upstream region of an inflation gas stream fed from a gas generator and a gas outlet section that opens toward an inflatable region of the airbag body and feeds an inflation gas to the inflatable region. The gas outlet section includes a check valve section. The check valve section has a flexible and a generally tubular shape extending and opening toward the inflatable region due to pressure of an inflation gas so as to stream the inflation gas into the inflatable region. After the gas generator has finished discharging the inflation gas, the check valve section folds back toward the gas upstream section due to an internal pressure of the inflatable region and closes off the gas outlet section.

Abstract: A side airbag apparatus has an inflatable portion, which is deployed and inflated on a side of a seat of a vehicle by inflation gas. The inflatable portion is divided into upstream and downstream sections by a partitioning member including a valve having an opening and a pair of valve body elements. Immediately after the beginning of the supplying of the gas, the valve body elements remain in contact with each other to close the valve. When the upstream section restrains an occupant, a force is exerted to the partitioning member by the occupant, which causes the partitioning member to warp and the valve body elements to be separated from each other to open the valve. The upstream section has a shoulder-protecting portion, which is deployed and inflated on a side of a region of the occupant including a rear end part and a middle part of a shoulder.
