Abstract
A side airbag device for a vehicle includes a lower chamber and an upper chamber to protect a passenger from a side impact in the event of a vehicle collision. The upper chamber is bent towards the passenger by a connecting tether to support a passenger'"'"'s neck region and prevent the neck from being twisted. The restraint belt forms an inserting space in front of a passenger when the upper chamber is bent so that a passenger'"'"'s shoulder region is inserted into the inserting space when the passenger is moved forwards by collision inertia. The passenger'"'"'s shoulder region is surrounded and supported by the restraint belt so that the passenger'"'"'s body is restrained by a seat. A passenger is protected from impact and simultaneously the passenger is restrained by the seat to minimize an injury.
