Abstract

A new and useful curtain air bag having an inflatable fluid cushion with inflatable fluid sections, and a flexible bladder located within the inflatable cushion. A fluid inlet conduit is configured to direct inflation fluid into the bladder from an inflation fluid source. The bladder is configured to redirect, diffuse and distribute the inflation fluid to the inflatable sections of the inflatable cushion, to inflate the portions of the inflatable cushion in a predetermined manner. Another type of curtain air bag assembly includes an inflatable cushion with a pair of similar volume inflatable sections, on opposite sides of an inlet conduit. In each type of air bag assembly, the fluid can be redirected by the bladder or the inflatable cushion, or by a transverse fluid conduit disposed in the bladder or the inflatable cushion.
