Definitions

  • the present invention relates to a pyrotechnic gas generator for inflating an airbag used in automobile safety.
  • the invention relates more particularly to a pyrotechnic gas generator comprising, inside an enclosure :
  • the present invention seeks to propose an improvement to this type of generator, to enable the absorption capacity of the airbag to be adapted to the nature and/or to the severity of the impact that results from an accident suffered by the motor vehicle, and/or to parameters associated with the occupants of the vehicle.
  • a given pyrotechnic generator of the type specified above corresponds to a single value of pressure and volume for the gas generated within an airbag.
  • one potential solution consists in causing the pressure that exists inside the airbag to drop and in matching the pressure drop to the various parameters mentioned above.
  • the vent acts as a conventional "passive" vent of the kind that is to be found in all airbags and that serves solely to contribute to deflating the airbag in order to hold the passenger's head.
  • the vent becomes active and opens to a greater extent, thereby causing the airbag to be vented to a greater extent.
  • pyrotechnic generators that include a tank for storing a cooling liquid. This liquid is sprayed into the plenum chamber or into an intermediate mixer chamber, where it is mixed with the hot gas leaving the combustion chamber.
  • Patent documents US-6 076 468, US-6 196 583, and US- 3 813 007 describe such generators.
  • the liquid is expelled from the tank by a displacement movement of a piston or by deformation of one of the walls of the tank, with the movement always being generated by the thrust that is exerted by the hot gas being released. That expulsion of cooling liquid thus takes place simultaneously with the release of hot gas and cannot be eliminated or deferred in time.
  • Patent document US—6 412 814 seeks to improve generators of the above-specified kind by controlling the ejection of the cooling fluid into the mixer chamber.
  • a generator includes an electrical control valve placed on a duct connecting the combustion chamber to the rear face of the piston. The valve can be operated to limit the passage of hot gas towards the piston, thus regulating not only the quantity of cooling liquid that is expelled into the mixer chamber, but also the instant at which such expulsion takes place.
  • An object of the invention is to remedy the above- mentioned drawbacks of the state of the art.
  • a particular object of the invention is to propose a pyrotechnic gas generator of the type mentioned in the introduction, that further comprises at least one cooling liquid storage tank, and that enables the pressure drop inside the airbag to be adapted to different types of occupant and to the conditions of the accident.
  • the generator must also be reliable and must not produce toxic gas.
  • said generator also comprises an activation device enabling said cooling liquid to be exhausted from said storage tank so as to be sprayed into the airbag, said activation device being actuated by a control device in a manner that is selective and independent of the operation of said combustion chamber.
  • said tank for storing the cooling liquid communicates with at least one exhaust orifice provided through the wall of said enclosure in such a manner as to allow the cooling liquid to be sprayed directly into the inside of said airbag;
  • said activation device comprises an ignitor and a piston suitable for moving under the action of the gas generated by the ignitor so as to reduce the volume of said storage tank and expel the cooling liquid therefrom; • said piston constitutes a portion of the wall of the cooling liquid tank;
  • control device acts on the activator device as a function of parameters associated with the type of impact on the motor vehicle, its violence, and the morphology or the positioning of the occupants;
  • said cooling liquid presents a freezing point below about minus 39°C and a boiling point above about 109 0 C;
  • cooling liquid is a mixture comprising about 50% water and about 50% glycol
  • the enclosure is tubular in shape and comprises a cylindrical wall closed at each of its ends by a closure ring, the enclosure is subdivided internally by a first partition and by a second partition extending perpendicularly to its longitudinal axis, said first partition, having the nozzle passing therethrough, separating the first combustion chamber from the plenum chamber, said second partition separating the plenum chamber from the cooling liquid tank, and said piston is suitable for sliding axially inside said enclosure towards said second wall, the discharge opening and the exhaust orifice being formed through said cylindrical wall of the enclosure; and
  • the invention also provides a method of inflating an airbag used in automobile safety, the method comprising a step consisting in ejecting hot gas into the inside of said airbag in order to deploy it.
  • the method further comprises a step consisting in spraying a cooling liquid directly into the inside of said airbag, simultaneously with the release of said hot gas, or subsequently thereto .

  • the generator comprises an enclosure 1 defined by a cylindrical wall 10 that is crimped at each of its ends onto closure rings 11, 13 that are generally in the form of disks.
  • References 101 and 103 designate annular beads that project inwards and serve to hold the wall 10 in place on the closure rings 11 and 13.
  • the generator extends along a longitudinal axis X- X' .
  • the wall 10 is also crimped in its central portion onto a disk-shaped transverse partition referenced 12.
  • the corresponding annular crimping bead is given reference 102.
  • the partition 12 and the closure rings 11 and 13 occupy planes that are perpendicular or substantially perpendicular to axis X-X'.
  • the partition 12 is pierced by at least one nozzle-forming orifice 120 which, by way of example, is in the form of a cylinder extended by a slightly flared portion.
  • the wall 10, the rings 11 and 13, and the intermediate partition 12 are traditionally made of metal having high strength and suitable for withstanding high temperatures. Nevertheless, the wall 10 is made of a metal that is sufficiently ductile to make crimping possible .
  • the intermediate partition 12 subdivides the inside of the enclosure 1 into two chambers, a "combustion” chamber 2 and a “filtering and plenum” chamber 4. For simplification purposes, this chamber is referred to in the description below as the "plenum" chamber. These two chambers are contiguous.
  • the generator also includes an ignitor 3 associated with a pyrotechnic charge 20, the ignitor 3 and the charge 20 both being situated in the combustion chamber 2.
  • the charge 20 is generally in the form of a cylindrical annular sleeve that is engaged inside the wall 10 of the enclosure.
  • the ignitor 3 is mounted in the central portion of the ring 11 and it is retained and centered against the inside face of said ring by means of an appropriate mounting member 30.
  • An 0-ring 31 provides sealing in this location.
  • the ignitor 3 is also provided with a pair of pins 32 for enabling it to be connected to an electric current source .
  • the charge 20 is held in place inside the chamber 2 by appropriate sintering means (not shown in the figure) , and it is also prevented from moving in translation by a grid 21 in the form of a cup that is interposed between the charge 20 and the intermediate partition 12.
  • the ignitor 3 is of conventional type and is advantageously an electro-pyrotechnic initiator. It includes an electrical initiator system and a fragmentable cap containing a pyrotechnic composition.
  • the pyrotechnic composition On being activated, the pyrotechnic composition releases flame and hot gas that in turn cause the pyrotechnic charge 20 to enter into combustion.
  • this charge is made up of a solid propellant suitable for generating a large quantity of hot gas very quickly.
  • a gas-permeable sleeve 40 of filter material is mounted inside the plenum chamber 4.
  • Its function is to retain certain particles that are present in the gas generated by combustion of the charge 20 so as to prevent these particles from escaping from the generator and penetrating into the airbag (not shown in the figures) .
  • the wall 10 of the enclosure is pierced by at least one radial hole 106, and preferably by a plurality of radial holes that are regularly distributed angularly if it is desired to have a generator that delivers neutral thrust.
  • a deceleration sensor produces an electrical signal which is transformed by the ignitor 3 into a pyrotechnic signal leading to combustion of the propellant charge 20.
  • the propellant generates hot gas in the combustion chamber 2 and the escape of the gas into the plenum chamber 4 is controlled by the nozzle orifice 120.
  • the generator in accordance with the invention is longer than the prior art generator, i.e. its cylindrical wall 10 extends beyond the plenum chamber 4 (to the left in Figure 2 ) .
  • the closure ring 13 is omitted and replaced by a second intermediate partition 14 of disk shape, preferably made of metal.
  • the wall 10 is crimped onto said partition 14 and the annular crimping bead is given reference 104.
  • This partition 14 defines the end of the plenum chamber 4.
  • the generator is also closed at its other end by a closure ring 15 identical to the ring 11.
  • the crimping bead is given reference 105.
  • An ignitor 8 is mounted in the central portion of the ring 15 and is held and centered against the inside face of said ring by means of a mounting member 80.
  • the ignitor 8 is also provided with a pair of electrically conductive pins 82.
  • the ignitor is an electro- pyrotechnic initiator of the same type as that referenced 3.
  • the ignitor 8 is connected to a control device (not shown in the figures) , and constituted for example by the computer on board the vehicle or by an electronics unit.
  • the generator also includes a disk-shaped piston 6 interposed between the ignitor 8 and the second intermediate partition 14.
  • the piston 6 is preferably made of metal.
  • the piston 6 co-operates with a portion of the wall 10 and the second partition 14 to define a tank 5 for storing a cooling liquid 50. It also co-operates with the ring 15 to define a second combustion chamber 7.
  • An O-ring 61 penetrates into a receiving peripheral groove 60 provided for this purpose around the periphery of the piston 6. Its function is to prevent the cooling liquid 50 from flowing into the inside of the second combustion chamber 7.
  • the O-ring 61 can be made of rubber.
  • the cooling liquid 50 must withstand the extreme operating temperatures to which the generator is exposed. For this purpose, it preferably presents a freezing point below -39°C (minus 39° Celsius) and a boiling point above about 109 0 C.
  • This mixture also has the advantage of not burning within the airbag and thus of not generating any additional combustion gas.
  • the piston 6 is movable in translation along the axis X-X' of the generator towards the partition 14.
  • the wall 10 of the enclosure is pierced by at least one radial exhaust orifice 51, and preferably by a plurality of radial orifices that are regularly distributed angularly.
  • each orifice 51 is closed by a closure membrane 52.
  • the orifice (s) 51 open(s) out directly into the inside of the airbag.
  • the generator operates as follows.
  • a deceleration sensor activates the ignitor 3 as explained above, thereby causing the airbag to be inflated.
  • a fraction of the gas contained in the airbag can escape through a passive vent formed in the airbag so as to damp reception of the body of the vehicle passenger.
  • control device can selectively activate triggering of the ignitor 8, i.e. it can ignite it or it can decide not to ignite it, and it can ignite it simultaneously with triggering of the ignitor 3, or subsequently.
  • Activation is performed as a function of various parameters, e.g. selected from: • the type of impact on the vehicle: for example a frontal impact or a lateral impact or a plurality of successive impacts;
  • the control device senses these various items of information using sensors that are present in the vehicle .
  • control device determines that it is necessary to activate the ignitor 8, it does this by delivering an electrical signal thereto. This causes the pyrotechnic composition contained in the fragmentable cap of the ignitor 8 to enter into combustion.
  • the pyrotechnic combustion releases a flame and a certain amount of hot gas that applies pressure against the piston 6, thereby causing it to move axially towards the partition 14. This reduces the volume of the tank 5 so the cooling liquid 50 is expelled therefrom, through the exhaust orifice 51 by piercing the membrane 52.
  • the cooling liquid 50 is sprayed directly into the inside of the airbag.
  • the exhaust orifice 51 is calibrated so that the liquid 50 is sprayed uniformly in very fine droplets into the inside of the airbag.
  • the instant at which cooling liquid begins to be sprayed is also selected to optimize not only the beginning of the pressure drop, but also the extent of the pressure drop.
  • the pressure drop depends on the initial temperature of the gas in the airbag, which itself decreases as a function of time by heat exchange with the airbag and by leakage through the passive vent.
  • the advantage of the invention also lies in the fact that the cooling liquid is sprayed directly into the airbag and not into a mixer chamber as in prior art devices .
  • the cooling liquid is sprayed into the gas present in the airbag when said gas is at a temperature that is generally lower than
  • the generator in accordance with the invention also makes it possible for the airbag to do without an active vent with controlled opening.
  • the generator could be of some other shape and that the second combustion chamber 7 and the liquid tank 5 could be positioned in some other way relative to the plenum chamber 4 and the combustion chamber 2.
  • the piston 6 could be omitted.
  • An ignitor on its own generates sufficient pressure to eject the cooling liquid.
