Abstract
A side airbag apparatus includes an airbag 50 that is inflated and deployed in a space between an occupant seated in a vehicle seat 12 and a vehicle body side portion by inflation gas that is supplied from an inflator 41 in response to an impact applied to the vehicle from a side. The airbag 50 has a lumbar region protecting portion 54 that is inflated and deployed beside at least the lumbar region PP of the occupant, thereby protecting the lumbar region PP. In the side airbag apparatus, the lumbar region protecting portion 54 has a part A at which the thickness in the vehicle widthwise direction is the greatest. The position in the vertical direction of the part A is lower than a highest point B in a front portion of the seat cushion 13 of the vehicle seat 12. These settings allow the part A to be inflated and deployed at a position that is spaced downward from the upper end 63U of an ilium of the occupant P.
