  • Variable mass flow airbag module
    Patent number: 5709405
    Abstract: A variable mass flow airbag module includes a housing having gas discharge ports in direct communication with an airbag to be inflated for rapidly inflating the airbag and adapted to receive gas from a pyrotechnic inflator, stored gas or hybrid inflator, or other type of inflator. The housing has a vent opening which is controlled by a valve to vent a controlled variable amount of gas to achieve a desired mass flow of gas into the airbag to provide a desired level of energy absorption capability for optimizing occupant protection.

  • High rate pressure vessel filling process
    Patent number: 5586587
    Abstract: The invention comprises a high rate pressure vessel filling process which improves the accuracy of filling pressure vessels to required gas mass. The approach overcomes heating effects of high rate filling and volume variation effects by slowly prefilling a series of temperature monitored and controlled cylinders of a set volume, then rapidly discharging the premeasured gas mass into the pressure vessel.

  • Inflatable restraint system inflator emission treatment
    Patent number: 5378015
    Abstract: A filter assembly, as well as a treatment system and an inflator module assembly including such a filter assembly are provided. The filter assembly is mounted within the module diffuser housing, external the side or end of an inflator from which gas is emitted and is effective in the treatment of the gaseous emission. Such treatment can include the filtration of particulate from the gaseous emission as well as redirecting the flow of such emission in a desired manner.
