Definitions

  • the present invention relates to a crash helmet with openable chinguard.
  • Crash helmets of the so-called full-face type in which the front part or chinguard is hinged to the helmet bowl and can be opened, have long been used, particularly by motorcyclists.
  • Full-face crash helmets with openable chinguard have many advantages in terms of comfort, especially when using the motorcycle or moped in town; accordingly their use is increasingly widespread.
  • the opening operation has to be very easy and quick.
  • EP-0518178 discloses a full-face helmet having a chinguard that can be opened with one hand by acting on a lever with the thumb. This system has however shortcomings: because of the position of the lever it is not possible to grip the chinguard while pulling it forward and this causes the head of the motorcyclist to be pulled forward as well. Furthermore, the lever is outside the chinguard.
  • the aim of the present invention is to provide a crash helmet with openable chinguard which overcomes the drawbacks of the conventional helmets and particularly allows to open the chinguard more easily, with just one hand.
  • An object of the invention is to provide a crash helmet, with openable chinguard, which provides a higher safety.
  • Another object of the invention is to provide a crash helmet with a chinguard closure system which is reliable in case of impact.
  • the crash helmet according to the invention includes a helmet bowl 3 and a chinguard 5 which is pivoted to the bowl 3 on a pivot 7, which is preferably constituted by a screw or the like.
  • the chinguard 5 can move into at least two positions: an open position, shown in Fig. 3, and a closed position, shown in Fig. 1. In the closed position, the chinguard can be locked to the bowl by a locking means 9, while in the open position the chinguard can be locked with respect to the bowl for example, by an engagement means 11.
  • the engagement means 11 includes a protruding part, advantageously constituted by a ball 13 or the like, which is elastically associated with the inner surface of the chinguard 5 and is suitable to engage a recess 15 formed on the outer surface of the bowl 3.
  • the chinguard 5 can of course assume different positions, with respect to the crown, in addition to the open and closed ones shown in Figs. 3 and 1, respectively.
  • the locking means 9 comprises lever members 17, each pivoted to one side of the chinguard 5 and including a hook 19 adapted to engage a coupling means, advantageously constituted by a slot 21 on each side of the bowl 3.
  • the locking means 9 can be actuated by an actuation member 23, which is advantageously constituted by a tie rod 25, whose ends 27 and 29 are associated with the levers 17.
  • a grip means, or push button, 31 surrounds the central part of the tie rod 25 and is slidingly associated, in a longitudinal direction, with the chinguard 5 by means of pins 33 which are rigidly coupled to the chinguard and are inserted in corresponding seats formed in the grip means.
  • the grip means 31 comprises first guiding flaps 35 which can slide in corresponding lateral seats formed in the chinguard.
  • the grip means thus forms a sliding push button inside the chinguard, rather than a lever, and it is very easy for the user to push the button and grip the chinguard with one action, using his/her thumb and index.
  • the chinguard is provided with second guiding flaps 37 surrounding the edge 39 of the bowl during closure of the chinguard.
  • the locking means 9 is normally kept in the locking position by means of elastic members.
  • levers 17 are kept in the locking position, shown in Figs. 1 and 2, by means of springs (not shown) which are coaxial to the fixing pivot 41.
  • the grip means is also normally kept in the position for locking the levers 17, by means of springs which are coaxial to the pins 33.
  • Chinguard 5 comprises an inner front horizontal wing 43 adapted to further guide the grip means 31.
  • the chinguard is released and the motorcyclist simply has to lift it with the same hand to move it into the chosen open position, for example in the position shown in Fig. 3, which is made stable by virtue of engagement means 11.
  • the crash helmet of course has a conventional visor 45 which is pivoted to the bowl 3 on the pivot 7 and has a per se known operation.
  • the grip means is substantially a sliding push button instead of a lever thus making its actuation easier.
  • a further advantage of the invention is the possibility to easily lock the chinguard in the open position and thus to also release it when one wishes to close it again.
  • a further advantage is the simple construction which helps to make the crash helmet more reliable.
  • a further advantage is given by the rounded profile of the grip means, which is shaped complementarily to the inner part of the chinguard so that it does not cause discomfort to the user and at the same time minimizes the longitudinal dimensions of the chinguard.
  • Still a further advantage over the prior art is that the entire mechanism, including the grip means or push button, is inside the chinguard thus improving safety, because there are no protruding parts, aerodynamics and the aesthetic appearance of the helmet.
  • the helmet according to the invention is susceptible of numerous modifications and variations, all of which are within the scope of the claims. All the details may be replaced with other technically equivalent elements. The materials used, as well as the dimensions, may of course be any according to the requirements and the state of the art.
