Side air bag incorporating inverted T-shaped flow barrier

摘要

A side impact air bag cushion which incorporates a flow barrier of inverted T-Shaped geometry at the interior. The flow barrier which may be in the form of a zero length tether includes a base portion and a leg portion extending away from the base portion. The base portion provides a partial barrier between the thorax protection portion of the air bag cushion and the head protection portion. The structure promotes desirable early inflation of the thorax protection portion of the air bag cushion as well as the substantially vertical inflated orientation of the head protection portion.
