Abstract:
A side impact air bag system comprising:a gas generating device attached to a vehicle seat, said gas generating device blowing gas toward a front side of said seat when a collision force applied to a side of a vehicle is detected; anda bag having a front side and a rear side and being connected to said gas generating device and deployed by said gas, said bag including:a first chamber positioned between a torso of a passenger and a vehicle side part when deployed, the gas blown from said gas generating device flowing directly into said first chamber to deploy said first chamber;a second chamber positioned between a head of the passenger and a vehicle side part when deployed, said gas flowing via said first chamber into said second chamber to deploy said second chamber; anda first separator extending along a front-to-rear direction of the seat when the bag is deployed for dividing said bag into said first chamber and said second chamber,wherein said first separator is positioned relative to the rear side of said bag such that a first communication passage is defined between the first separator and the rear side of the bag for connecting said first chamber and said second chamber and such that gas is communicated between the first and second chambers via the first communication passage only at the rear side of the bag while the bag inflates, andwherein said gas blown from said gas generating device to the seat front side is deflected to said first communication passage by an inner surface of the seat front side of said first chamber, and further deflected to the seat front side to deploy said second chamber by an inner surface of the seat rear side of said first communication passage when passing said first communication passage.
