Abstract: A side airbag module for a vehicle includes an airbag cushion and an inflator to supply gas to the airbag cushion to deploy the airbag cushion. The airbag cushion includes first and second regions to protect a shoulder and a chest of an occupant, respectively, and, when the airbag cushion is initially deployed by driving of the inflator, the first region pushes the shoulder of the occupant toward an interior of a vehicle so that a portion of load applied from the second region to the chest of the occupant is moved to the shoulder of the occupant. When the airbag cushion is initially deployed due to vehicle collision, the shoulder of the occupant is pushed toward the interior of the vehicle to move the load applied to the chest of the occupant to the shoulder of the occupant, thereby minimizing the injury degree of the occupant.
