More Information
Summary:A side curtain air bag provides a region to assist a slower region to unfold at a faster rate during air bag deployment. A first region is relatively uninflatable compared to a second inflatable region. The inflatable second region is generally located between the first region and an upper end portion of the air bag. The first region includes two end points and the inflatable second region provides a way for increasing the deployment rate of the first region by extending between the two end points. The inflatable second region height is at least 40% of a height of the air bag to ensure adequate assistance to the first region in unfolding. A gas distribution hose and vent allow inflation gas to flow through and into the inflatable second region to increase the deployment rate of the second region.
