Definitions

  • the present invention relates generally to the sector of providing protection by means of an inflatable element, so as to protect a user from impacts, following falling or sliding, for example when performing any activity or when travelling on a means of transport, such as a vehicle, preferably a two-wheeled vehicle, or any other means of transport, such as a horse or other animal, sports equipment, such as a pair of skis or a bobsleigh, or similar means of transport.
  • a means of transport such as a vehicle, preferably a two-wheeled vehicle, or any other means of transport, such as a horse or other animal, sports equipment, such as a pair of skis or a bobsleigh, or similar means of transport.
  • the present disclosure relates to an inflation device for inflating an inflatable element for protecting a user in the event of falls and/or impacts of various types.
  • protection devices including inflatable elements, which are inflated in the event of an impact by an inflation device which is in fluid communication with the said inflatable element.
  • an inflation device is formed by a fluid source, such as a canister which contains compressed gas and which is opened by means of a punch, or a small explosion, or a pyrotechnic gas canister which expands, also following a small explosion, which is managed by means of an electric activation signal.
  • gas generator Any form of fluid source intended to determine the outflow of pressurised gas into an inflatable element is referred to in the continuation of the present disclosure by the term "gas generator".
  • Protection devices are normally formed by an inflatable element, the aforementioned gas generator, sensors for detecting the fall or the impact and at least one control unit for managing the activation of the gas generator in order to inflate the inflatable element.
  • the entire protection device is then associated with a garment, for example inside a pocket, or joined to it by means of a connection system of the known type.
  • the gas generator is arranged inside the inflatable element, for reasons of convenience, so as to facilitate the fluid connection with the inflatable element.
  • One problem forming the basis of the present disclosure is that of providing an inflation device which allows a user to replace a gas generator without necessarily removing the inflatable element and which may also have other advantages and also providing a protection device which includes said inflation device.
  • the present disclosure is based on the recognition by the inventor of the present disclosure that it is possible to incorporate the gas generator in a container and form a single body therewith.
  • the container acts as a handle or gripping body for the gas generator.
  • the container consists of a closed container which may be opened in an irreversible manner at the time of use of the gas generator, so as to open a gas outlet zone and allow the gas generator to be placed in fluid communication with the inflatable element.
  • the container may be formed by two shells which are joined together by calibrated breakage means which are broken at the time of use. These calibrated breakage means are, for example, breakable bridge-pieces between the two shells.
  • the container is therefore able to prevent direct contact between an end user and the gas generator.
  • the assembly formed by the container and the gas generator may then be coupled to an inflatable element by means of a detachable coupling device. In this way, a user may change only the gas generator without having to remove the inflatable element.
  • the inflatable element may be configured to allow several inflation operations and ensure the same protection performance after a number of inflation operations.
  • the main advantage therefore consists in the fact that it allows direct contact with the gas generator to be avoided since the user may handle the container or only one of the two shells if the other one is removed following breakage.
  • the gas generator container therefore acts as grip for the gas generator.
  • a user may handle the gas generator by means of the container and connect by means of coupling the inflation device to the inflatable element in a quick and safe manner.
  • the inflation device may advantageously be arranged in a garment so as to be easily reached by a user.
  • a user may avoid coming into direct contact with the gas generator and avoid the risks associated with direct handling thereof.
  • each embodiment may have one or more of the advantages listed above; in any case it is nevertheless not necessary that each embodiment should have simultaneously all the advantages listed.

  • This inflatable element 50 is intended to protect at least partially a body area of the user, for example a top area of a user's torso.
  • said inflatable element 50 may be connected to the inflation device 10 in an area of the spinal column.
  • the connection area is however not an essential characteristic of the present disclosure.
  • the connection is advantageously provided where said connection may be easily accessed by a user.
  • the inflation device 10 includes at least one gas generator 12 and a container 14 for containing said at least one gas generator 12.
  • the gas generator 12 is provided with a region 16 intended for the passage of gas, namely a region which, when the gas generator 12 is activated, allows gas to pass towards the inflatable element 50.
  • the gas generator 12 may be provided, as is known, with a shut-off valve, not visible in the drawings.
  • the gas generator 12 may be a canister containing compressed cold gas, such as helium.
  • the gas generator 12 may be a gas generator of the pyrotechnic or hybrid type or of other types known in the state of the art.

  • the first guide seat 81 has an L-shaped form or a right-angled form.
  • the L-shaped or right-angled form allows the first plug-in component 71 to slide along the first guide seat 81 and, once the angle of the L-shaped or right-angled form is reached, by means of relative rotation of the coupling component 18 and the coupling counter-component 52 it is possible to prevent a further sliding action of the first plug-in component 71. In this way uncoupling of the coupling component 18 and the coupling counter-component 52, and therefore of the gas generator 12 and the inflatable element 50, may be prevented.
  • the inflation device 10 further comprises a ring nut body associated with the coupling counter-component 52 and configured to prevent the first plug-in component 71 from coming out of the first guide seat 81.

  • the gas generator 12 may be coupled to the coupling counter-component 52 of the inflatable element 50 by means of direct gripping of the container 14.
  • the main body 31 of the container 14 therefore acts as a handle or gripping body for the gas generator 12, for example during coupling together of the gas generator 12 and the inflatable element 50.

  • the device according to the present disclosure may also be applied using an activation cable connected to a vehicle ridden/driven by a user, which cable activates inflation of the inflatable element following the movement of the user away from the vehicle, for example following a fall or a sudden impact. Use of a cable is employed in particular in the horse-riding sector.
