Abstract

The present invention is a torso protection system having braided tubes that inflate upon side or oblique impact to protect the torso of a seated vehicle occupant. Prior to inflation, the braided tubes are mounted in the undeployed state along both sides of the occupant's seat. When an impact is detected, a gas generator generates, inflating the braided tubes. As the braided tubes inflate, their diameters increase and their lengths decrease substantially. The braided tubes then pull out of their storage locations and form bolsters on either side of the seated occupant. The inflated tubes prevent the torso of the occupant from directly colliding with interior side structures of the vehicle and restrict the lateral motion of the occupant.
