Pyrotechnical composition for safety systems of passive protection, particularly for use in airbag or safety belt pre-tensioner

摘要

In the present invention, there is disclosed a pyrotechnical composition for safety systems of passive protection, particularly for use in airbag or safety belt pre-tensioner containing a fuel, an oxidant, a binding agent, and optionally also an process additive, wherein in concrete terms the pyrotechnical composition according to the present invention contains 5 to 45 percent by weight of fuel comprised of bis(1-amidino-O-alkyl urea) copper nitrate (wherein tie alkyl in the formula is represented by a hydrocarbon radical of the general formula CinHi2n+1, in which n = 1 through 10), 50 to 90 percent by weight of the oxidant, 4 to 20 percent by weight of the binding agent and 0 to 5 percent by weight of process additives.
