Abstract

A hybrid inflator for inflating an airbag system has one or more heater assemblies with an enhancer charge contained in the heater with bypass ports or openings in direct communication with the inert gas. Upon ignition a portion of the enhancer charge bypasses the heater gas generant charge to pre-heat the inert gas prior to or simultaneously with a remaining portion of the enhancer charge igniting the heater gas generant charge.
