Definitions

  • the present invention relates to the field of pyrotechnic initiators and more specifically concerns an electro-pyrotechnic initiator intended for the automotive safety.
  • Electro-pyrotechnic initiators are traditionally made from two pins conductive of electricity which are maintained by a overmolding of insulating material and the ends of which are connected to each other by a filament resistive heater which is enclosed in a pearl igniter made from a primary explosive such as lead trinitroresorcinate or styphnate lead and whose lower ends are connected to a source of electrical current.
  • Such initiators can be used to initiate protective devices by airbag of occupants of a vehicle automotive, as explained in patent GB-A-2,019 198.
  • Such electro-pyrotechnic initiators are widely used to build devices ignition of pyrotechnic gas generators intended to inflate protective cushions for occupants of a motor vehicle.
  • a ferrite core like this is for example described in patents U-S-A-4,722,551, EP-A-0 512 682 and US-A-5 355 800.
  • the resistive filament heater is sometimes replaced by a printed circuit having a resistive and heating part like this is, for example, described in patent application FR-A-2 704 944 or in its correspondent US-A-5 544 585.
  • the support of the printed circuit can have the form of a thin parallelepiped map.
  • these printed circuits generally have a topography complex that uses both sides of the support as described for example in patent EP-A-0 150 823.
  • the object of the present invention is precisely to propose such an initiator by removing the pins and ferrite cores and integrating their functions in a simple PCB, unlike anything that has been done so far.
  • the PCB holder will normally made from one of the insulating materials usually used to make such supports.
  • the electromagnetic protection means of the initiator against stray currents can be consisting of at least one filter coil deposited on said circuit support.
  • the filter coil can itself be printed on said circuit support and constitute with said electrical circuit a multilayer printed circuit.
  • Said means of electromagnetic protection can still be made up of at least one capacitor deposited on said circuit support.
  • the said electrical circuit and the said means of protection electromagnetic will be covered by a layer of insulating varnish.
  • the circuit support covered or not by a layer of insulating varnish, will also be partially coated with an insulating overmold of so as to leave only the part of the support free circuit carrying the covered resistive heating element by the thermosensitive load.
  • the charge thermosensitive is not itself at least partially maintained by the said overmolding, it will be advantageously protected by a fragmentable mask.
  • the said circuit support has the form of a thin parallelepiped card with two opposite flat faces allows you to make electro-pyrotechnic initiators in which on each of the two flat faces of the circuit support is printed a separate circuit of conductive strips each including a resistive heating element covered by a thermosensitive load and means of electromagnetic protection. It is thus possible to constitute an initiator who presents, for a source single electric, two separate ignition heads and which is particularly reliable and safe.
  • the invention also relates to an electro-pyrotechnic igniter characterized in that an initiator according to the invention is surrounded by a fragmentable cap containing powdered ignition powder.
  • the invention finally relates to the use of a electro-pyrotechnic initiator according to the invention for cause the ignition of a pyrotechnic generator gas intended to inflate a protective cushion for occupant of a motor vehicle.
  • the initiator may be used directly to switch on the load generator pyrotechnic when it is under form of grains or pellets, it will advantageously used via an igniter as described higher when the load is in block form compact.
  • the invention thus makes it possible, from small very simple and very economical printed circuits carry out, constitute initiators or space-saving and very reliable igniters.
  • Figure 1 is a perspective view, with partial cutaway, of an igniter formed from an initiator according to the invention shown for reasons of clarity of the figure without protective mask.
  • FIGS. 2 , 3 and 4 illustrate the successive stages of constitution of an initiator according to the invention from its circuit support.
  • FIG. 5 illustrates a printed circuit on which the electromagnetic protection is provided by capacitors.
  • FIG. 6 illustrates a printed circuit on which the electromagnetic protection is provided by a traditional filter coil.
  • FIG. 7 illustrates a printed circuit on which the electromagnetic protection is provided by a coil printed in a multilayer circuit.
  • FIG. 8 is a sectional view of an initiator comprising two separate ignition heads, the heat-sensitive charges of which are partially maintained by overmolding.
  • FIG. 1 shows an igniter 1 consisting of an initiator 2 connected to a cable electric 3.
  • the initiator 2 is contained mainly in a cylindrical overmold 4 having on the cable side 3 a base 5 of diameter slightly higher.
  • the initiator 2 has, at its end opposite to the base 5, an ignition head which will be described in details a little further but which can be observed that it has a thermosensitive filler 6 based on lead trinitroresorcinate which is protected by a mask 7 made of transparent plastic not shown in Figure 1.
  • a metal cap fragmentable 8 of cylindrical shape encloses the overmolding 4 by resting on the base 5. This cap is closed at its end opposite the base 5 and contains a pyrotechnic charge 9 generator gas.
  • the constitution of initiator 2 is now described in detail with particular reference in Figures 2 to 5.
  • the initiator 2 is formed from of a printed circuit support 10 which has the form of a thin parallelepiped card with two sides opposite planes.
  • This support 10 is formed from an epoxy resin loaded with glass fibers.
  • On one two conductive strips 11 are printed on its faces and 12 which are each welded at one of their ends to the conductive wires 13 and 14 constituting the cable electric 3.
  • a resistive heating element 15 connects between them the free ends of the strips conductive 11 and 12.
  • This resistive heating element 15 can be a resistive wire but will be advantageously consisting of a defined resistive heating strip by a printed sub-circuit 16 as described in the patent US-A-5, 544 585 or in its correspondent FR-A-2 704,944, the description of which is included, by reference, to this description.
  • the resistive heating element 15 may also be made up of a diode or a semiconductor bridge as described for example in the request for Patent FR-A-2,720,493.
  • Two capacitors 17 and 18 are removed and connected to the circuit formed by the strips conductive 11 and 12 as well as by the resistive element 15. These capacitors are the means of electromagnetic protection of the circuit by preventing discharge of stray currents through the element 15.
  • electromagnetic protection means could also consist of a coil filter 61 deposited and connected to a printed circuit on a support 60 and constituted by two strips conductive 62 and 63 interconnected by an element resistive 64 as shown in Figure 6.
  • a variant for making such electromagnetic protection is shown in Figure 7.
  • On a support 70 is printed a circuit consisting of two strips conductive 72 and 73 interconnected by an element resistive 74.
  • the conductive strip 72 forms around the support 70 a coil 71 constituting with the strip 73 a multilayer circuit.
  • the part of the face of the support 10 on which are printed strips 11 and 12 and on which rest capacitor 17 and 18 is covered by a layer of insulating varnish 19.
  • This layer 19 does not cover the end of the support 10 which carries the resistive element 15 and which will constitute the ignition head of initiator.
  • the support 10 is partially surrounded by a cylindrical overmolding 4 in adhesive resin based on hot-melt polyamide.
  • thermosensitive filler 6 for example based on lead trinitroresorcinate.
  • Load 6 is protected by a mask 7 made of transparent plastic. Initiator 2 is thus completed and can be used to constitute the igniter 1 described above.
  • FIG. 8 shows an initiator 82 which constitutes an alternative embodiment of the initiator 2 which has just been described.
  • Initiator 82 is built around a card-shaped circuit support 80 thin parallelepiped.
  • the essential difference between this initiator 82 and the initiator 2 described more high resides in the fact that each of the two faces of the support 80 carries a complete printed circuit 87 or 89 connected to the same 83 power supply cable electric.
  • the support 80 is partially coated with a cylindrical overmolding 84 which has a base widened 85 and which partially maintains the loads thermosensitive 86 and 88 constituting the heads ignition. In this realization, the initiator does not no protective mask required.
  • thermosensitive In case of arrival current through cable 83 both loads thermosensitive are simultaneously ignited and initiator 82 thus presents a very large efficiency in normal operation and very high safety both with regard to stray currents thanks to its electromagnetic protections 91.93 or 92.94 integrated only vis-à-vis possible misfires thanks to the doubling of the heads.
