摘要： An airbag including an expansion part accommodating inflow of expansion gas to expand a peripheral wall, and linear joining portions arranged in a region of the expansion part and constituted by joining facing portions of the peripheral wall in a linear manner. The linear joining portions include a linear base, curved portions and swelling portions. Each of the curved portions is connected to the base and curvilinearly extends and bends toward the respective base thereof. The swelling portions are arranged at tip ends of the curved portions to smoothly connect outer peripheral edges thereof to outer peripheral edges of the curved portions. With this airbag, stress concentration is reduced around the swelling portions and the curved portions at the time of development and expansion. Thus, the linear joining portions can be arranged without causing breakage of the peripheral wall during development and expansion, and reduction in volume and expansion area held down as much as possible.

摘要翻译： 一种气囊，包括容纳膨胀气体的流入以膨胀周壁的膨胀部分，以及布置在所述膨胀部分的区域中并且以线性方式连接所述周壁的相对部分而构成的线性接合部分。 线状接合部包括线状基部，弯曲部和隆起部。 每个弯曲部分连接到基部并且曲线地延伸并朝着其相应的基部弯曲。 隆起部分布置在弯曲部分的末端处，以将其外周边缘平滑地连接到弯曲部分的外周边缘。 利用该气囊，在展开和膨胀时，在膨胀部分和弯曲部分周围的应力集中减少。 因此，可以布置线性连接部分而不会在显影和膨胀期间引起周壁的破损，并尽可能地减小体积和膨胀面积。
