Patent attributes
An object is to be able to more appropriately restrain respective portions of an upper body, including a waist portion, of a passenger by a side airbag at a time of a side collision. At a time of a side collision, a side airbag receives a supply of gas and deploys between a passenger and a vehicle body side portion, and an upper bag portion restrains from a head portion to a shoulder portion, and a lower bag portion restrains a waist portion, and an intermediate portion, that connects a lower edge portion of the upper bag portion and an upper edge portion of the lower bag portion, restrains a chest portion. Load, that is imparted toward a vehicle transverse direction inner side from the upper bag portion to the shoulder portion of the passenger at this time, decreases at a latter stage of restraint of the shoulder portion by the upper bag portion, and therefore, an amount of movement of the shoulder portion toward a vehicle transverse direction inner side is suppressed to an appropriate degree.
