Definitions

  • the present invention relates to a portable device for rapid inflation of an inflatable bag such as, for example, an avalanche protection airbag.
  • the device according to the invention comprises at least one inlet intended to be connected to a source of compressed gas under high pressure, to allow the latter to relax in an air intake chamber, the input being associated with a mechanism for triggering the release of compressed gas to the air intake chamber.
  • the latter has an opening intended to allow the admission of surrounding air and an outlet intended to be connected to the bag to be inflated.
  • the gas is injected into a cylindrical air intake chamber provided in each of the inflation mechanisms by an injection nozzle disposed substantially in alignment with the central axis of the air intake chamber.
  • the latter has a plurality of openings in its side wall to allow the suction of surrounding air as a consequence of the injection of the gas under high pressure.
  • the sucked air is accelerated by Venturi effect to quickly inflate the corresponding inflatable bag with a sufficient volume, by applying a factor of multiplication (volume of air / volume of compressed gas) to that of the volume of compressed gas available, thanks to the addition of air.
  • Each of the inflation mechanisms further comprises a check valve to prevent the corresponding inflatable bag from deflating through the inlet when it is fully inflated.
  • compressed air As an alternative to nitrogen, it is also known to use compressed air as compressed gas under high pressure.
  • the multiplication factor applied in the known devices is not very high, of the order of 2 to 3 (that is to say that the volume of surrounding air injected into the airbag is the order of 2 to 3 times the volume that represents the gas in the airbag once it is decompressed) and requires the use of a large volume of compressed gas to inflate the airbag.
  • the size of the compressed gas cartridge thus contributes significantly to the overall size of the inflation device, which is why the above-mentioned US patent proposes an architecture of the device in a modular form, that is, that is to say to arrange the various components of the device in different places of a bag, for example.
  • an avalanche protection airbag should be inflated in approximately 2 to 4 seconds.
  • a main object of the present invention is to overcome the drawbacks of inflation devices known from the prior art, by proposing such a device that effectively meets the constraints set out above, in particular by making it possible to inflate an airbag in the delay required and, having a small footprint and ease of assembly / disassembly.
  • the present invention relates more particularly to an inflation device of the type mentioned above, characterized in that it comprises an intermediate chamber for dispensing the compressed gas, arranged between the inlet and the inlet chamber of air to connect them to each other and a plurality of ejection holes arranged to open into a side wall of the air inlet chamber to connect the latter to the intermediate distribution chamber .
  • the device according to the invention is more efficient in the implementation of the surrounding air intake, which enables it to achieve a multiplication factor greater than that of known devices and therefore to resort to the use of smaller compressed gas cartridges.
  • the intermediate distribution chamber is generally at least partially annular and is arranged at the periphery of the intake chamber.
  • the side wall of the inlet chamber into which the ejection holes open is located between the opening and the outlet.
  • the device comprises a first cylindrical tube whose internal wall defines the side wall of the intake chamber, and a second cylindrical tube, coaxial with the first tube and arranged at least partially around it for define between them the intermediate chamber of distribution. At least two seals are provided to delineate the latter in an axial direction.
  • the first and second tubes are advantageously secured to each other by screwing or by means of a bayonet mechanism.
  • Such an architecture ensures a simplified manufacturing process of the various components of the device, as well as their assembly or disassembly, for example for maintenance operations.
  • the ejection holes preferably have an inclination substantially between 10 and 20 degrees with reference to the longitudinal direction of the device and a diameter substantially between 0.2 and 1 mm, preferably between 0.5 and 0.8 mm. .
  • the device advantageously comprises between 2 and 10 ejection holes.
  • the inlet has a fastener for a sealed cartridge containing a compressed gas under high pressure.
  • the triggering mechanism may comprise a first needle controlled by a user actuable drive mechanism, to be moveable between at least first and second positions and to perforate the sealed cartridge to release the compressed gas therefrom.
  • the fixing member may advantageously comprise a tapping which can cooperate by screwing with a thread provided on the sealed cartridge.
  • the device comprises a second input similar to the first input, intended to receive a second sealed cartridge of compressed gas and, associated with an additional trigger mechanism comprising a second needle, arranged to be controlled simultaneously with the first needle and perforate the second sealed cartridge to release the compressed gas.
  • carbon dioxide cartridges can be used.
  • carbon dioxide is a gas that has good compressibility, which allows to store a large potential volume in a cartridge of the type used in current airbags. This is one of the reasons, in addition to its low price, for which this gas is generally used to inflate lifejackets in vehicles such as boat or plane, for example.
  • the intake chamber comprises an acceleration cone arranged between the ejection holes and the outlet, preferably having a length substantially between 60 and 150mm.
  • the device advantageously comprises a reversible attachment member to an inflatable pocket, the latter preferably being arranged at a distance from the exit, so that the acceleration cone is likely to be at least partially accommodated in the pocket. inflatable in use configuration.
