Definitions

  • the present invention relates to pyrotechnic gas-generating compounds, suitable for use in systems for protecting occupants of motor vehicles, more especially for the inflation of damping cushions (called “airbags”) and more particularly for the inflation of airbags.
  • airbags damping cushions
  • side cushioning cushions so-called side “airbags” (see below)).
  • Side airbag systems differ from front airbag systems essentially by the time required for deployment and installation of the airbag. Typically, this time is shorter for a side airbag (of the order of 10-20 ms, against 40-50 ms for a front airbag).
  • a side airbag the functional need to inflate the bag over a short period of time requires the use of a pyrotechnic composition having a sufficiently high combustion speed (typically equal to or greater than 30 mm / s, or even 35 mm / s, at 20 MPa ) over the operating pressure range in the combustion chamber of the generator, in order to obtain a sufficient inflation surface flow value (product pxnx Tc x Vc).
  • the pyrotechnic composition must also have good ignitability characteristics. Also, taking into account the generally declining surface profile of the loadings employed (of the pellet type), the composition should ideally exhibit a stable and sufficiently high combustion rate at low pressure.
  • the side airbags is more restrictive than that for the front airbags. Obviously, any technological advance in the field of said side airbags can also advantageously be applied in the field of front airbags.
  • a pressure P such as: 0.1 ⁇ P ⁇ 10 MPa, by medium pressure, a pressure P such that: 10 MPa ⁇ P ⁇ 30 MPa, by high pressure, a pressure P such that: P ⁇ 30 MPa.
  • the desired increase in the combustion rate of the pyrotechnic compound in question is therefore not only necessary to increase the gas flow rate in order to achieve the inflation time specifications, but also to ensure the ignitability of the compound without resorting to the use of a relay charge and the harmlessness of the combustion products.
  • said combustion temperature must not be too high (it must at least remain below 2400 K, more favorably below 2350 K) so that the temperature of the gases in the damping pad does not affect the integrity. occupant's physical condition.
  • a low combustion temperature makes it possible, on the one hand, to limit the thickness of the bag and, on the other hand, to simplify the design of the gas generator by making it possible to reduce the presence of baffles and filters within it. this.
  • the side airbag systems can use two types of gas generators: those called entirely pyrotechnic (the gas generation is then ensured exclusively by the combustion of a pyrotechnic charge) and those called “hybrid” (the gases then coming from a joint combustion of a pyrotechnic charge and a volume of neutral gas stored under pressure in a sealed tank).
  • gas generators those called entirely pyrotechnic (the gas generation is then ensured exclusively by the combustion of a pyrotechnic charge) and those called “hybrid” (the gases then coming from a joint combustion of a pyrotechnic charge and a volume of neutral gas stored under pressure in a sealed tank).
  • the pyrotechnic charge must not have a combustion temperature that is too low so that the combustion gases are hot enough to compensate for the temperature drop caused by the expansion of the volume of the pre-compressed neutral gas. .
  • combustion temperatures above 2000 K are required.
  • pyrotechnic compounds which are suitable for use in fully pyrotechnic gas generators or in hybrid generators, more particularly intended for side airbags, that is to say simultaneously having a moderate combustion temperature of the order of 2000-2400 K, more favorably 2000-2350 K, and a high combustion rate over the entire operating pressure range (especially greater than 30 mm / s at 20 MPa, more favorably greater at 35 mm / s at 20 MPa) , including at low pressure .
  • the basic ingredients of the compounds be pyrotechnically non-hazardous.
  • ingredient (s) belonging to the class of explosives such as nitroguanidine, hexogen (RDX), octogen (HMX).
  • Explosive ingredients are understood to mean ingredients classified in risk division 1.1 according to standard NF T 70-502 (see also UN - Recommendations on the Transport of Dangerous Goods - Manual of Tests and Criteria, Fourth Revised Edition, ST / SG / AC.10 / 11 / Rev.4, ISBN 92-1-239083-8ISSN 1014-7179 and STANAG 4488 ).
  • Guanidine nitrate and potassium perchlorate, taken separately, are not ingredients classified in this risk division. They do not constitute explosive ingredients, in particular within the meaning of the invention.
  • These compounds also include in their composition a low level of a ballistic catalyst, consisting of an oxygenated compound of a transition metal, advantageously with a high specific surface area, traditionally used in the field of propellants to increase the combustion rate at medium and high pressure (this catalyst accelerates the decomposition of the oxidizing charge).
  • a ballistic catalyst consisting of an oxygenated compound of a transition metal, advantageously with a high specific surface area, traditionally used in the field of propellants to increase the combustion rate at medium and high pressure (this catalyst accelerates the decomposition of the oxidizing charge).
  • Gas micro-generators for belt tensioner devices as described in said patent US 6,893,517 (and in its priority request EP 1 275 629 ) operate in pulses, which requires a high rate of combustion at medium and high pressure.
  • a strong exponent of pressure at low pressure and the non-combustion at atmospheric pressure of the compounds in question do not pose a problem, insofar as the pressure does not drop, in the context of use of said compounds, to a low level before the end of pyrotechnic operation.
  • This application for belt tensioner devices does not require, for the gas generator, requirements as severe as those required in the context of the present invention (airbags, and more particularly side airbags), in particular a high combustion speed. at low pressure, a lowering of the combustion pressure limit threshold (as close as possible to atmospheric pressure) and a low pressure exponent over the entire combustion range (especially at low pressure).
