The purpose of the present invention is to suppress upward pressing of an arm of a passenger by an airbag at the initial stage of deployment and inflation. An airbag (31) in a non-inflated expanded configuration in which the airbag is expanded in a planar shape without being filled with an inflation gas is folded into a stowed configuration. An airbag (31) in a non-inflated deployed state is provided with: a lower inflation section (42); and an upper expansion part (45) which is adjacent to the upper side of the lower expansion part (42) in a communicating state. In the storage state, the upper expansion part (45) is folded in a corrugated shape in the vertical direction while alternately changing the folding direction. In the storage state, at least a portion of the lower expansion section (42) is disposed further away from the specific side wall section (side frame section (18) side: left side) than the upper expansion section (45).
抑制乘员的臂部由展开及膨胀的初期的气囊向上按压。不填充膨胀用气体而以平面状展开的非膨胀展开形态的气囊(31),通过折叠而形成为收纳用形态。非膨胀展开形态的气囊(31)具有:下膨胀部(42);以及上膨胀部(45),其以连通的状态与下膨胀部(42)的上侧相邻。在收纳用形态下,上膨胀部(45)一边交替地改变折返方向一边在上下方向上折叠为波纹状。在收纳用形态下,下膨胀部(42)的至少一部分配置于比上膨胀部(45)更靠远离施加有冲击的特定侧壁部一侧(侧部框架部(18)侧:左侧)。
