    Abstract: An airbag of a side airbag apparatus includes an upstream inflation portion, which inflates by inflation gas, and deploys frontward at a side of a vehicle seat. An opening is provided at a wall portion of the upstream inflation portion. A pressure regulator valve closes before an occupant is restrained by the upstream inflation portion, thereby restricting the inflation gas in the upstream inflation portion from flowing through the opening. Upon the occupant restraint, the pressure regulator valve cancels the restriction in response to a change in a tensed state of the dividing portion by an external force applied due to the restraint. A tear seam that connects valve body portions of the pressure regulator valve delays the opening time of the pressure regulator valve upon the occupant restraint by the upstream inflation portion relative to the opening time set only by the pressure regulator valve.

    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: 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 translation: 安全气囊包括气囊本体和内管。 内管包括位于从气体发生器和气体出口部分供给的充气气体流的上游区域中的气体上游部分，气体出口部分朝向气囊本体的可充气区域打开，并将充气气体供给到可充气区域。 气体出口部分包括止回阀部分。 止回阀部分具有柔性且大致管状的形状，由于膨胀气体的压力而朝向可膨胀区域延伸并开口，以便将充气气体流入可充气区域。 在气体发生器完成排放充气气体之后，由于可充气区域的内部压力，止回阀部分向气体上游部分折回并且关闭气体出口部分。
