Definitions

  • the present invention relates to a crash-helmet in particular for motorcyclists.
  • jet-type crash-helmets are constituted by a substantially dome-shaped shell made of rigid material, such as for example polycarbonate or glass fibers, which is open at the front and below.
  • An adequately shaped layer of shock-proof material usually foamed polystyrene, is arranged inside the casing or shell.
  • a layer of soft padding is furthermore applied on the inner side of the layer of shock-proof material and allows the inside of the helmet to adapt to the user's head.
  • Jet-type helmets are usually secured to the head of the user by means of a strap which extends transversely to the lower opening and is tensioned or fastened after the helmet has been put on so as to downwardly embrace the user's chin.
  • This kind of helmet has some disadvantages, mainly related to the use of the strap to secure the helmet to the user's head.
  • the strap is in fact not fastened or tensioned adequately, making the securing of the helmet unstable, with the possibility of an easy loss thereof due to accidental causes, in particular in case of falls, impacts, etc.
  • the strap is furthermore often uncomfortable when the helmet must be worn for a long time.
  • the strap is also used as a helmet securing element for a wide range of helmets of the closed type, i.e. with a chin-rest which extends on the front opening of the helmet, practically with the same disadvantages observed in "jet"-­type helmets, though accidental removal of the helmet is made more difficult by the presence of the chin-rest.
  • the strap is replaced by a lower extension of the chin-rest which limits the helmet lower opening to a passage for the neck.
  • the chin-rest is movable with respect to the shell of the helmet so that it can be moved forward to allow the user's head to pass through the lower opening when the helmet must be put on or removed.
  • the aim of the present invention is to solve the above described problems by providing a crash-helmet, which can be safely secured to the head of the user.
  • an object of the invention is to provide a helmet which always ensures an adequate aeration of the front lower region, in particular for helmets of the closed type.
  • Another object of the invention is to provide a helmet which forces the user to secure it correctly when it is to be used.
  • Not least object of the invention is to provide a helmet which is easy to put on and to remove.
  • FIGS. 1 to 7 illustrate the helmet according to the invention in the first embodiment, with reference to a "jet"-type helmet, and more particularly:
  • the crash-helmet according to the invention comprises a substantially dome-shaped shell 2 which is open at the front and below.
  • the shell 2 is obtained in a known manner and is made of rigid material, for example polycarbonate or glass fibers, and a layer of shock-proof material, for example foamed polystyrene, is provided inside it, together with a layer of padding.
  • a layer of shock-proof material for example foamed polystyrene
  • a substantially rigid retention element 3 extends in a front region of the lower opening 4 and its longitudinal ends 3a and 3b extend upward and are oscillably associated with two opposite lateral regions of the shell 2.
  • the retention element 3 is controllably movable from a closed position, in which it downwardly delimits the front opening 5 of the helmet and downwardly embraces the chin of the user, to an open position, in which it is moved forward and upward with respect to the closed position to allow the user to easily put the helmet on or remove it.
  • the longitudinal ends 3a, 3b of the retention element 3 are slidably associated with the shell 2 through guiding means 6 in the shape of an arc of a circle.
  • Said guiding means comprise, for each of the ends 3a and 3b, a tab 7 which has the shape of an arc of a circle and engages a correspondingly shaped seat 8 defined by an interspace provided on the inner side of the shell 2 starting from the respective lateral edge of the front opening 5.
  • a first slot 9 is defined on the tab 7 and has the shape of an arc of a circle; a first pin 10 engages therein and is associated with the shell 2; the tab 7 is provided with a second pin 11 which is inserted in a second slot 12 which is also in the shape of an arc of a circle and is defined on the bottom of the seat 8 inside which the tab slides.
  • the length of the two slots 9 and 12, which are mutually concentric, determines the extent of the possible oscillation of the retention element 3.
  • Snap locking means 13 for locking the retention element 3 at least in its closed position are advantageously provided.
  • Said snap locking means comprise a radial expansion 14 of the first pin 10, which is provided with a head 10a which can be accessed from the outer side of the helmet and can be controllably moved along its axis toward the inside of the helmet in contrast with elastic return means comprising a helical spring 15 which is arranged around the pin 10 and is located in an adapted accommodation 16 defined on the bottom of the seat 8.
  • a recess 17 which is defined on the inner side of the tab 7 and is shaped correspondingly to the radial expansion 14 so as to couple therewith by the action of the spring 15 when the retention element is in closed position.
  • the ends 3a and 3b of the retention element 3 define abutments 18 which are directed toward the lateral edges of the front opening 5 and rest against them when the retention element 3 is in closed position, so as to provide excellent resistance to the backward movement of the retention element 3 in case of frontal impact.
  • the retention element 3 is provided, in its intermediate portion 3c located in a downward region of the helmet, with an anatomically shaped flattened configuration with a concavity 19 on the side directed toward the rear part of the helmet, so as to be comfortable for the user.
  • Said retention element 3 can be provided monolithically by molding rigid synthetic material coated, at least on the side directed toward the user, with soft material, such as for example foamed polyurethane or other padding materials.
  • a layer 20 of padding material can be provided on the inwardly directed side of the ends 3a and 3b, so that said ends perform an effective action for protecting the lateral regions of the user's face which is particularly advantageous in the first embodiment, i.e. in "jet" type helmets.
  • the longitudinal ends 3a and 3b of the retention element 3 are joined by a bridge-like element 21 which extends in front of the helmet 1a and defines a chin-rest of a closed helmet.
  • An aeration passage 22 is conveniently defined between the chin-rest 21 and the intermediate portion 3c of the retention element 3.
  • the chin-rest 21 and the retention element 3 may be provided monolithically.
  • the use of the helmet according to the invention is as follows.
  • the retention element 3 With the helmet on, the retention element 3 is returned to its closed position by acting thereon in the opposite direction. When the end closed position is reached, the retention element 3 is locked by the spring 15, which causes the radial expansions 14 to engage the recesses 17.
  • the helmet according to the invention fully achieves the intended aim, since the retention element ensures an excellent securing of the helmet to the user's head, avoiding the disadvantages of strap securing in known helmets.
  • Another advantage which derives from the adoption of the retention element according to the invention in jet-type helmets is that the lateral and lower parts of the user's face are better protected.
  • the materials employed, as well as the dimensions, may be any according to the requirements and to the state of the art.
