Definitions
- the present invention relates to the field of automotive safety and relates more particularly to a electro-pyrotechnic igniter.
- electro-pyrotechnic igniters have, on the one hand, pins metallic connected to an electric current source and between which a core of ferrite, and on the other hand, a resistive heating element which is attached to said metal pins and which is covered with a pyrotechnic priming composition.
- the resistive element heater can consist of a resistive strip heater integrated in a printed sub-circuit.
- the skilled person is therefore always looking electro-pyrotechnic igniters capable of being integrated in a cable network connected to a central processing unit control and with similar external dimensions to that of traditional lighters.
- the object of the invention therefore relates to an electro-pyrotechnic igniter according to claim 1.
- the means of dialogue and trigger will be a specific integrated circuit and the coded information which circulates between the central unit control and said means of dialogue and trigger will consist of pulse trains specific electrical.
- the coded information will include both information constituting the trigger orders for different igniters and information allowing the central control unit to ensure the reliability of electronic components contained in each igniter.
- the means of dialogue and trigger is placed on one of the two sides planes of the electronic card and storage medium of electrical energy is placed on the other flat face.
- the dividing transverse wall is carried out using a metal part bearing several perforations, each of these perforations having a glass side wall.
- the metal part carries two perforations and the electrical connection means are constituted by two metal connection pins, each being inserted into one of the two perforations carried by the metal part and having a first end attached to the resistive element heating and a second end welded to the tracks conductive.
- This dividing transverse wall therefore ensures sealing between the chamber upstream and downstream chamber before and after operation from the igniter but also to electrically isolate the metal connection pins to each other.
- the electronic card is arranged perpendicular to the transverse wall separating.
- the resistive heating element consists of a thin layer resistive bridge resting on the metal part, said resistive bridge in thin layer consisting of tantalum nitride whose thickness is between 0.01 ⁇ m and 1 ⁇ m.
- the resistive bridge could also consist for example in a layer of a nickel / chromium alloy.
- the pyrotechnic composition priming is a lacquer based on trinitrorésorcinate of lead which covers the resistive bridge. said initiating pyrotechnic composition can also consist for example of salts of dinitrobenzofuroxan.
- the external electrodes are formed by external metallic pins which are arranged in line with the map which are parallel to this card.
- the storage means of electrical energy consists of a capacitor.
- the invention also relates to the use of such electro-pyrotechnic igniters in gas generators for air bag modules connected in a motor vehicle via a bus-type cable network to a central control unit.
- Figure 1 is a partial sectional view longitudinal of an electro-pyrotechnic igniter according to the preferred embodiment of the invention with omission of electronic components and part of coating.
- Figure 2 is a cutaway perspective view of the igniter partially shown in Figure 1 with omission of the coating.
- Figure 3 is a diagram of a wired network of bus type in which four air-bag modules are integrated each containing an electro-pyrotechnic igniter shown in Figures 1 and 2
- an electro-pyrotechnic igniter 1 consists of a cap 2 which is provided a side wall 6 ending, on the one hand, with a bottom 4, and on the other hand, by a free end 33, and in which a liner 3 is first inserted cylindrical.
- the latter has a first end resting against the bottom 4 of the cap 2 and a wall lateral 5 whose external surface is in contact with a part of the internal surface of the side wall 6 of the cap 2.
- a pyrotechnic ignition composition 7 in the form of a powdery substance is then introduced into the cap 2.
- An assembly, described below, is finally slipped into said cap 2.
- This set is made from a glass passage which comprises, on the one hand, a piece discoid metal 8 having an upstream face and a downstream face to which a resistive element is attached heating 11, and on the other hand, two connection pins 13, 14 metallic.
- the piece discoid metal 8 has two perforations each comprising a side wall 9, 10 made of glass
- the two metallic connection pins 13, 14 are each introduced into one of the two perforations and said pins 13, 14 each have a first end fixed by welding to the resistive element heating 11.
- the latter is advantageously carried out at using a thin-film resistive bridge consisting of tantalum nitride, the thickness of which is approximately 0.5 .mu.m.
- a printed circuit support in the form a rectangular electronic card 17 having a upper flat face 26 and a lower flat face 27 on which are arranged conductive tracks 18, 19, is attached to connection pins 13, 14. More specifically, the second end 24, 25 of each of two connection pins 13, 14 is fixed by welding to the conductive tracks 18, 19 on the flat face upper 26 so that edge 28 of the rectangular electronic card 17 either in contact with the upstream face of the discoid metal part 8.
- a electrical energy storage means 20 consisting of a capacitor as well as protection means 21, 22 against electrostatic discharge and against electromagnetic disturbances are connected to conductive tracks 18, 19 on the upper flat face 26 and a means of dialogue and triggering of a specific electrical pulse train is connected to the conductive tracks 18, 19 on the flat face lower 27.
- the electronic card 17 rectangular is further extended by three external metal pins 29 to 31 each having one end fixed by welding on the tracks conductive 18, 19, said external pins 29, 30 being fixed on the upper flat face 26 and intended to be integrated into a cable network of the type bus attached to a central control unit and the external pin 31 being fixed on the flat face lower 27 and ensuring grounding.
- a 12-pyrotechnic initiation composition the form of a lacquer based on trinitrorésorcinate lead is deposited on the resistive heating element 11 and the assembly as described above is introduced in the cap 2, the discoid metal part 8 being placed on the second end of the liner 3 cylindrical.
- a plastic part 32 is inserted into the cap 2 and the free end 33 of the latter is set on part 32.
- a thermosetting polymer coating is then injected through a hole presented by the part 32 so as to fill the interior of the Exhibit 32.
- An electro-pyrotechnic igniter 1 as described previously presents an operating diagram next.
- the means of storage 20 of electrical energy constituted here by a capacitor, is regularly supplied with current low intensity emitted by the central unit of control and transmitted to said capacitor via external pins 29 and 30.
- the unit control center issues a trip order in the form of a train of electrical pulses specific which can only be detected by means of dialogue and trigger included in the igniter 1.
- This means of dialogue and triggering then makes it possible to apply the capacitor which is therefore caused to free, in the two connection pins 13, 14 and therefore in the resistive heating element 11, the quantity of electrical energy that was stored.
- Said element resistive heater 11 then causes, by Joule effect, initiation of the pyrotechnic initiation composition 12, and consequently, the initiation into combustion of the ignition pyrotechnic composition 7, which has effect of fracturing the bottom 4 of the cap 2.
- an advantage important is that when activating of igniter 1, the various electronic components are not damaged by the resulting pressure wave the initiation of the pyrotechnic composition boot 12, and the means of dialogue and trigger is then still able to exchange information with the central control unit in the following milliseconds, especially to signify it for example that the triggering of igniter 1 has been correctly executed.
- FIG. 3 we observe a diagram showing an example of a wired bus network in which a central control unit is integrated 110 as well as four air bag modules 111a, 111b, 111c and 111d, the two airbag modules 111b and 111c being able to example each contain a gas generator intended for inflate a frontal protection cushion, and both other airbag modules 111a and 111d which can for example each contain a gas generator intended to inflate a side protection cushion.
- the gas generator included in each of these different modules contain an electro-pyrotechnic igniter as previously described which presents so three external pins 114 to 116 metallic, the two external pins 114 and 115 being intended to be connected to a first supply conductor electric 112 attached to the central control unit 110 and the external pin 116 being intended to be connected to a second electrical conductor 113 attached also to the central control unit 110 and serving grounding.
- the central control unit 110 delivers periodically a low intensity electric current in the first power supply conductor 112, and this electric current is transmitted by means of electrical energy storage of the igniter included in each of the four air-bag modules 111a, 111b, 111c and 111d via external pins 114 and 115.
- the central control unit 110 delivers in the first power supply conductor 112 a train of specific electrical pulses constituting a trigger order for the module igniter airbag 111c.
- This train of electrical pulses is transmitted to each igniter by through external pins 114 and 115 but only the means of dialogue and trigger included in the igniter of the air bag module 111c is able to detect and analyze it.
- the means of energy storage electric associated with dialogue and trigger included in the air bag module igniter 111c is then requested and it causes the initiation of the pyrotechnic initiation composition as described previously.
- the unit command center 110 then delivers in the first power supply conductor 112 trains specific electrical impulses intended for the igniter included in each of the 111a air-bag modules and 111b.
- the operation of each of the two igniters is then analogous to that analyzed above.

Description
Mais là apparaissent plusieurs problèmes à résoudre consistant dans le fait :
- qu'un tel allumeur doit posséder un encombrement externe similaire à celui d'un allumeur couramment utilisé de façon à pouvoir se substituer à ce dernier dans les modules air-bag,
- qu'en cas de collision, l'unité centrale de commande peut ne pas être en mesure de délivrer suffisamment d'énergie électrique pour provoquer l'initiation des différents allumeurs inclus dans les modules air-bag,
- et qu'en fonction de la nature et de l'intensité de la collision par exemple, il est souhaitable de pouvoir choisir uniquement le déclenchement des modules air-bag permettant d'apporter une protection adaptée.
- cet allumeur électro-pyrotechnique peut être utilisé pour le même usage qu'un allumeur traditionnel puisque l'emploi d'une carte électronique sur laquelle sont intégrés les différents composants électroniques permet de conférer audit allumeur objet de l'invention un encombrement externe similaire à celui d'un allumeur traditionnel,
- l'utilisation d'un tel allumeur dans chacun des différents modules air-bag incorporés dans le véhicule et reliés par un réseau câblé de type bus à une unité centrale de commande permet, d'une part, de laisser le choix à l'unité centrale de commande de ne déclencher que le ou les modules air-bag susceptibles d'apporter une protection efficace à l'occupant en fonction du choc, et d'autre part, de ne plus demander à l'unité centrale de commande de délivrer la quantité d'énergie électrique nécessaire pour provoquer l'initiation d'un tel allumeur. Ceci est obtenu grâce à la présence dans chaque allumeur, d'une part, d'un moyen de stockage d'énergie électrique périodiquement alimenté par un courant électrique de faible intensité émis par l'unité centrale de commande, et d'autre part, d'un moyen de dialogue et de déclenchement qui est apte à détecter une information codée provenant de l'unité centrale de commande et à donner l'ordre audit moyen de stockage d'énergie électrique de délivrer la quantité d'énergie électrique jusqu'alors stockée. Celle-ci permet de chauffer l'élément résistif chauffant par effet Joule de manière à initier la composition pyrotechnique d'amorçage.
