Composition and process for inflating a safety crash bag
First Claim
Patent Images
1. A method for inflating an automobile or aircraft safety crash bag comprising the combustion of a pyrotechnic material, comprising at least one tetrazole or triazole compound containing hydrogen in the molecule, to generate substantially non-toxic combustion products including a gas to inflate said crash bag, said method comprising:
- A. burning said pyrotechnic material at elevated pressure in admixture with at least one oxygen containing oxidizer compound and at least one additional material so as to produce, upon combustion, a metal chloride salt and a substantially non-toxic primary gas mixture andB. diluting said primary gas mixture with air to produce a substantially non-toxic final gas mixture by passing said primary gas mixture through at least one venturi so as to aspirate said air, whereby said crash bag, when inflated contains a final gas mixture comprising about one to about four volumes of air per volume of said primary gas mixture.

Abstract
Composition and process for inflating an automobile or aircraft safety crash bag comprising igniting a pyrotechnic composition to generate a gas which is admixed with air by means of an aspirating venturi which results in substantially non-toxic products which are thereafter utilized to inflate said crash bag.

- 11. A pyrotechnic material useful to generate substantially non-toxic combustion products including a gas to inflate a crash bag, said pyrotechnic material comprising at least one tetrazole compound containing hydrogen in the molecule or a triazole compound containing hydrogen in the molecule, in admixture with at least one oxygen containing oxidizer compound and at least one additional material so as to produce, upon combustion, a substantially non-toxic gas and a metal chloride salt.
