Definitions
- the present invention relates to the field of electro-pyrotechnic initiators intended, in particular, to initiate occupant protection systems of a motor vehicle such as for example seat belt tensioners or generators gas to inflate protective cushions. More precisely the invention relates to an electro-pyrotechnic initiator whose resistive heating element is consisting of a thin layer bridge that works with very low energy.
- electro-pyrotechnic initiators intended for automotive safety were constituted by an insulating body of electricity extended by a fragmentable metal cap and crossed by two electrodes.
- the electrodes are linked together by a suspended resistive filament heating surrounded by an explosive composition initiation consisting of a primary explosive or a redox mixture as described for example in the US Patent 3,572,247.
- Such initiators exhibit however the disadvantage of being sensitive to vibrations of the motor vehicle at the welds of the resistive filament on the electrodes. These welds, when they are repeatedly requested by vehicle vibrations, can break and make the inoperative initiator, which means that this technology is gradually being abandoned today.
- the “all fire” current corresponds to the limit of the intensity of an electric current above which we are sure that all the igniters in a batch will operate.
- the “no fire” current corresponds to the limit of the intensity of an electric current below which it is certain that no igniter in a batch will work.
- the object of the present invention is precisely to propose such an initiator.
- a deposit as a resistive element in a thin layer on a support which is both insulating of electricity and very bad conductor of the heat and by imposing special conditions of particle size with primary explosive present in the priming composition, it is possible to constitute a electro-pyrotechnic initiator which operates from reliably with very low energies, around of a few hundred microjoules and which, when the components are well sized, present currents of all fire and non-fire compatible with the new requirements of car manufacturers.
- Said electrical circuit and said support will be advantageously constituted by a component, "C.M.S.” mounted on the surface of the solid body.
- Such components are still known by their abbreviated Anglo-Saxon appellation "S.M.D. (Surface Mounted Device).
- wedge not conductive of electricity and having two opposite planar faces is glued by one of its faces planes on the planar upper face of said massive body and the other flat face of the hold carries two layers separate conductive metals which are each at contact of one of the two electrodes and on which is fixed, by means of two conductive welds of electricity, the C.M.S.
- said container and said massive body are held together by a non-overmolding conductor of electricity and which is crossed by two electrodes.
- the support will consist of a material chosen from the group consisting of silica vitreous, mineral glasses containing silica, organic resins and plastics composites containing at least one organic resin and mineral fibers.
- said support consists of a material chosen from the group made up of mineral glasses containing silica.
- the different primary explosives suitable for the condition of grain size expressed above are likely to be used but we prefer, for reasons of operating reliability, use the salts of dinitrobenzofuroxane and in particular the rubidium salt of dinitrobenzofuroxan (RbDNBF) and the potassium salt of dinitrobenzofuroxan (KDNBF).
- the binder of the priming composition will advantageously be constituted with vinyl or acrylic resin.
- Said flat resistive element will be advantageously constituted by tantalum nitride.
- Figure 1 is an axial sectional view of a cylindrical initiator according to the invention.
- Figure 2 is a top view of the circuit electric by thin film deposition used in the initiator shown in Figure 1.
- Figure 3 is a partial sectional view of the massive body carrying the wedge and the C.M.S. such used in the initiator shown in Figure 1.
- FIG. 1 An electro-pyrotechnic initiator 1 according to the invention is shown in Figure 1.
- This initiator 1 consists of a cylindrical container 2 fragmentable open at one of its ends.
- a body massive cylindrical 3 closes the open end of the container 2.
- the side wall 4 of the body 3 has a external shoulder 5 on which the end is supported container 2 open.
- container 2 and body 3 are enclosed in an overmolding 6 which holds them in solidarity with each other.
- Container 2 thus has the shape of a cylindrical cap having a wall side 7 and a flat upper wall 8.
- the container 2 is advantageously constituted by a thin light metal like aluminum and its flat wall 8 is advantageously weakened to be able to open easily due to increased pressure prevailing inside the container.
- Overmolding 6 is preferably made in a resin thermoplastic such as, for example, terephthalate polyethylene.
- Body 3 must be able to function as a wall impervious to detonation and combustion gases resulting from this detonation.
- This body 3 is preferably made of a dense metal such as steel.
- the body 3 has a flat upper face 9 and a lower face 15 also flat and it encloses over its entire height h, a hollow glass tube 10.
- Two electrodes 12, 13 in the form of a cylindrical pin pass through the body 3, the electrode 12 passing through it through the hollow glass tube 10.
- Each electrode has one end that protrudes the planar upper face 9 of the body 3 and one end which exceeds the lower face 14 of the overmolding 6.
- an insulating shim 16 which is located thus arranged inside the container 2.
- Wedge 16 is based on charged polyepoxy resin of glass fibers and has the shape of a disc comprising two cylindrical channels intended to let through during the assembly of initiator 1, the electrodes 12 and 13.
- the wedge 16 carries on its upper face two plies distinct and non-contiguous metallic elements of copper 21 and 22; the upper ends of electrodes 12 and 13 are each connected to one of the layers 21 and 22 at welds 27 and 28 made of an alloy conductor of electricity.
- a SMD component constituted by a support 26 in the form of a parallelepiped chip, the upper face of which carries an electrical circuit 18.
- the support 26 consists of an ordinary "flint" glass containing between 20% and 55% silica SiO 2 . Such a glass is an excellent electrical insulator and a very poor conductor of heat, its thermal conductivity being of the order of 6mW / cm ° C.
- the circuit 18 consists of a deposit 29 in a thin layer of tantalum nitride partially covered by deposits in thin layers 30 and 31 of conductive metals based on gold and palladium. As shown in FIG.
- the deposits 29, 30 and 31 have trapezoidal shapes which leave uncovered a central parallelepipedal area 17 of the deposit 29 made of tantalum nitride.
- This zone 17 constitutes the resistive heating element in a thin layer of the electrical circuit 18.
- a tin solder 32 encloses one of the ends of the support 26 so as to ensure an electrical connection between the conductive deposit 30 and the conductive sheet 22 while a separate solder 33 also made of tin encloses the opposite end of the support 26 so as to ensure an electrical connection between the conductive deposit 31 and the conductive sheet 21.
- the electrical circuit 18 comprising the resistive heating element 17 is covered by a pyrotechnic initiation composition 23 constituted for 80% of its weight by the rubidium salt of dinitrobenzofuroxane and for 20% of its weight by an epoxy resin acting as a binder .
- the particle size of the primary explosive RbDNBF was close to 20 ⁇ 10 -6 m.
- Container 2 also contains a powder ignition 25 consisting, for example, of a powder nitrocellulose base or by a mixture of boron and potassium nitrate.
- a powder ignition 25 consisting, for example, of a powder nitrocellulose base or by a mixture of boron and potassium nitrate.
- Such an initiator is particularly simple and economical to mass produce.
- the wedge 16 thus fitted is glued to the flat upper face 9 of the solid body 3 so as to constitute a head of initiation which is covered by the composition priming 23 before introducing it into container 2 containing the ignition powder 25. It then suffices to join together thanks to overmolding 6.
- the initiators according to the invention can operate reliably with very low energy, of the order of 100 to 200 micro-joules or even from 1x10 -4 to 2x10 -4 J, and, when their constituent elements and in particular the resistor element 17 are well dimensioned, they have current values of any fire close to 1200mA and non-fire current values greater than 500mA. Furthermore, the initiators with thin film deposits being very resistant to vibrations, the initiators according to the invention find a preferred application in the field of protection, by electro-pyrotechnic devices, of the occupants of a motor vehicle.
- Initiator No. 1 corresponds to a thick layer bridge initiator, on a non-heat conducting support and with a priming composition using an oxidation-reduction mixture.
- Initiator No. 2 corresponds to a thick layer bridge initiator, on a non-heat conducting support and with a priming composition using a primary explosive.
- Initiator # 3 is a thin layer bridge initiator on a heat conducting support with a priming composition using a primary explosive

Abstract
Description
- D'une part, les initiateurs dont les nappes conductrices et la bande résistive sont constituées par des circuits imprimés ou encore par des feuilles « en couches épaisses » photogravées dont l'épaisseur est supérieure à 2x10-6m et souvent comprise entre 2x10-6m et 7x10-6m, ou encore entre 2 et 7 micromètres. De tels initiateurs sont par exemple décrits dans le brevet US 5 544 585. De tels initiateurs ont une bonne résistance aux vibrations du véhicule automobile, mais nécessitent, comme les initiateurs à filament, une énergie relativement importante pour fonctionner.
- D'autre part, les initiateurs dont la bande résistive est constituée par un dépôt « en couche mince » dont l'épaisseur est inférieure ou égale à 1 x 10-6m ou encore 1 micromètre et qui est déposée par évaporation sous vide sur son support. De tels initiateurs sont par exemple décris dans les brevets US 5 798 476 ou encore US 4 729 315. Ces initiateurs ont une bonne résistance aux vibrations du véhicule automobile et présentent de surcroít l'avantage de présenter un courant de non feu d'au moins 400 mA avec un courant de tout feu voisin de 1200 mA ce qui est de plus en plus demandé par les constructeurs automobiles et qui n'est pas offert par les initiateurs à filament ou à « couches épaisses ».
Le courant de « tout feu » correspond à la limite de l'intensité d'un courant électrique au dessus de laquelle on est sûr que tous les allumeurs d'un lot fonctionneront.
Le courant de « non feu » correspond à la limite de l'intensité d'un courant électrique en dessous de laquelle on est sûr qu'aucun allumeur d'un lot ne fonctionnera.
