Abstract
An all-pyrotechnic inflator, for generating an inflating gas, includes: an elongated enclosure means, a linear ignitor, and a pyrotechnic material. The elongated enclosure means has a longitudinal axis and an outlet means for passage of the gas. The linear ignitor is arranged within the enclosure means and extends along at least part of the longitudinal axis of the enclosure means. The pyrotechnic material is disposed within the enclosure means and extends along at least part of the longitudinal extent of the enclosure means for combustion and generation of gas upon ignition by the linear ignitor. The enclosure means further includes an inner wall, an outer wall, a nozzle means, and a means for maintaining substantially constant pressure during generation of the gas. The pyrotechnic material is the sole source of the inflating gas.
