Abstract:
1. A vehicle side air bag apparatus comprising: a bag that is housed within a side portion which is outside in a seat back of a vehicle seat in a vehicle width direction and inflates and expands to a vehicle front side of the side portion by supplying gas in an inner portion of the bag; an up-down partition that partitions the bag into a lower bag portion for lumbar constraint and an upper bag portion for upper body constraint; a right-left partition which partitions the lower bag portion into left and right chambers aligned in the vehicle width direction in an inflation and expansion state, to which a right-left communication port that allows mutual communication between the left and right chambers is provided and which inhibits inflation of the lower hag portion in an upper and lower direction by being extended in the inflation and expansion state; an inflator provided in the upper bag portion; and a flow regulating portion that distributes gas from the inflator into one of the left and right chambers and the upper bag portion and limits gas flow from the one of the left and right chambers to the upper bag portion by a check valve portion that protrudes to the one of the left and right chambers.
