PURPOSE: A side air bag cushion of a vehicle is provided to distribute flow of gas evenly through a whole cushion by preventing concentration toward a second expansion part, thereby preventing damage of passengers who sit in a bad posture due to the rapidly expanding cushion. CONSTITUTION: A side air bag cushion of a vehicle includes a first partition film(200) for connecting an upper part(500) to a lower part(100), and formed with an auxiliary discharge hole(212) at a side and a discharge hole(211) at a top part to form a single discharge part(110), a sewing part(230) connecting a part of the upper part and a part of the lower part to a lower part of the discharge hole of the discharge part for discharging gas gathered to the discharge part while separating, wherein the sewing part is torn off by a force more than a predetermined pressure applied by the gas so that the upper and lower parts are separated from each other, thereby rapidly discharge the gas via the discharge hole.
