Definitions

  • the invention relates to a protective helmet according to the preamble of claim 1.
  • helmets consist of a hard outer shell designed to fit on the user's head, and which in "full face” helmets also extends across the front, forming a tapered section known as a chin guard.
  • the area between the chin guard and the crown can be optionally closed with a flip-up visor, usually hinged on either side.
  • the interior of the hard shell is padded with a layer of impact-absorbing material such as polystyrene foam, lined for comfort and hygiene with fabric where it comes into contact with the head and face of the wearer.
  • a layer of impact-absorbing material such as polystyrene foam
  • helmet manufacturers produce outer shells in two or three sizes at most, and then vary the thickness of the internal impact liner to obtain a range of sizes that can fit the majority of purchasers.
  • the fit should also be sufficiently snug to prevent the helmet being shifted or partially dislodged by the airflow while in motion, especially when travelling at high speed on motorcycles which afford minimal aerodynamic protection to the driver.
  • the helmet should not be so tight that it feels painful or causes headaches after prolonged use.
  • helmets constructed in the conventional manner outlined above have certain drawbacks.
  • the internal conformation of the helmet will not necessarily suit the anatomy of all wearers, and can at times even result in discomfort due to the pressure exerted on certain areas, especially at the front. This is the reason why, for example, helmets produced for the Asian market have a different shape from those produced for Europe: to take into account the different anatomical head shape of oriental populations.
  • US-A-4 038 700 discloses interconnected air cushions providing a variable padding thickness in various parts of the helmet.
  • the purpose of the invention is to design a protective helmet that can be perfectly conformed to the anatomical shape of each user.
  • An additional purpose of the invention is to design a protective helmet whose internal dimensions are not subject to alteration after a certain period of use.
  • the number label (1) designates a protective helmet constructed according to this invention.
  • Helmet (1) consists of an outer shell (2) made from a hard, impact-resistant material which comprises at least one essentially hemispherical top section (3), or crown, and two side sections (4a, 4b) extending from the edges of the crown (3).
  • the side sections (4a, 4b) meet at the front and form a single piece with crown (3), thereby defining a front portion (5) with an opening (6) that can be optionally closed with a visor (7), and a rear portion (8).
  • side sections (4a, 4b) afford protection to the area of the ears and the nape of the neck.
  • helmet (1) comprises a tapered element (9) which joins together the ends of side sections (4a, 4b) to form a chin guard.
  • helmet (1) also comprises a number of inserts (10) of deformable material which partially or entirely cover the inner surface of the hard shell (2), to absorb any impacts.
  • inserts (10) of deformable material which partially or entirely cover the inner surface of the hard shell (2), to absorb any impacts.
  • the interior of hard shell (2) contains at least one expandable liner (11) to create air-tight chambers(12) provided with means for inflation and deflation (13).
  • Chambers(12) can therefore retain gases such as air, enabling them to go from an inflated state where chambers(12) are filled with pressurised gas, to a deflated state where the internal pressure of the gas is substantially the same as the external air pressure.
  • the aforesaid means for inflation and deflation (13) are situated on the chin guard and consist of a pump (14), for example a diaphragm pump, that is used for inflating chambers(12), as well as some means (140) for connecting the pump (14) to the chamber (12).
  • the aforesaid means (140) for connecting the pump (14) to the chamber (12) can consist, for example, of one or more segments of hose.
  • the means for inflation and deflation (13) additionally comprise a one-way valve element (15), operationally connected to the aforesaid means (140) for connecting the pump (14) to the chambers(12).
  • the said one-way valve element (15) permits the inflation of chambers(12) but prevents the air retained inside chambers (12) from coming out.
  • said means (16) for opening the one-way valve element (15) consist, for example, of a button (151) connected to a control device (150), where control device (150) is fitted on the one-way valve element (15).
  • the means for inflation and deflation (13) can be realised by substituting pump (14) with a tube for blowing air into chamber (12).
  • an expandable liner (11) forms an air-tight bag (17) which defines a chamber (12), and whose outermost surface (17a) is in direct contact with the hard shell (2) while the inner surface (17b) is in contact with the wearer's head.
  • the inner surface (17b) is lined with a hypoallergenic fabric (18) to assure the comfort of the user.
  • a bag (17) is contained between the hard shell (2) and the inserts (10), which are therefore covered with the above-mentioned fabric material (18).
  • several bags (17) are positioned at predefined points, for example at the front and/or the sides and/or the neck area at the back.
  • the various bags (17), each provided with its own means for inflation and deflation (13), can be inflated at different pressures in order to achieve an even more personalised fit of helmet 1.
  • helmet 1 constructed according to this invention is extremely simple.
  • the user puts on the helmet 1 which fits loosely on the head. After donning the helmet, the user operates pump (14) to fill bag (17) with air until its volume causes the inner surface of helmet 1 to adhere snugly to the head and face. Before removing helmet 1 it is sufficient to operate the means (16) for opening the one-way valve element (15), allowing the air contained in bag (17) to come out.
  • the helmet according to this invention assures a perfect custom fit on the wearer's head, affording safety and comfort at the same time.
  • the helmet according to this invention allows users to choose the most appropriate configuration for each occasion, for example a very snug "sports" fit for short journeys, or a more comfortable “touring” fit for longer trips.
  • the helmet is extremely comfortable to put on and remove, because it does not need to be forcefully pulled on or off.
