Definitions

  • the present disclosure relates in general to the technical sector of protective helmets. More particularly, the present disclosure relates to a protective helmet comprising a cap and a chin strap device, fixed to the cap, and at least one tie element.
  • a chin strap device formed for example by a belt fixed to the cap in two side regions of the helmet and configured to be closed underneath the jaw of a user wearing the helmet.
  • the chain strap device according to the prior art is able to prevent accidental removal of the helmet due to a movement of the cap away from the user's head since the chin strap device is able to engage with the user's jaw and prevent movement of the cap.
  • the helmets according to the prior art do not solve the technical problem of improving the performance of the helmet as regards preventing rotation of the cap with respect to the user's head, in particular a rotation tending to expose at least partially a frontal zone of the head.
  • This problem may negatively affect the level of protection offered by the helmet since the cap is unable to protect effectively the whole of the user's head in the event of rotation.
  • the starting point of the present disclosure is therefore the technical problem of providing a helmet, which is able to satisfy all the aforementioned requirements with regard to the prior art and overcome the aforementioned drawback and/or achieve further advantages.
  • the present disclosure relates to a helmet configured to protect the head of a user and comprising a cap and an internal cavity positioned or defined inside the cap and intended to accommodate the head of a user.
  • the cap defines an internal cavity intended to accommodate the user's head.
  • the internal cavity has an access zone, configured to allow access of the user's head inside the internal cavity.
  • the cavity also has a front portion, defining a front opening, and a rear portion, opposite to the front portion.
  • the helmet also comprises a chin strap device comprising in turn at least one belt structure which is fixed at least to respective side portions of the cap, each comprised between the front portion and the rear portion.
  • cap is understood, in the context of the present disclosure, as meaning the assembly forming the rigid structure for protecting and accommodating the user's head.
  • the belt structure extends transversely with respect to the cap between the two side portions of the cap and the zone for access to the internal cavity. Furthermore, a zone of the side portion comprised between the belt structure and the front opening is a front side zone of the cap, and a zone of the side portion comprised between the belt structure and the rear portion is a rear side zone of the cap.
  • the access zone is located underneath the cap, and the chin strap device extends underneath the cap between the two flanks of the latter.
  • any spatial reference, such as “above”, “below”, “front”, “rear”, “frontal”, “right”, “left” and similar indications in the context of the present disclosure are to be understood as being of a non-limiting nature, but as referring to when the helmet is in use and therefore in relation to the head of the user wearing the helmet.
  • the helmet also comprises at least one first tie element which extends along the front side zone and a second tie element which extends along the rear side zone.
  • a first part or end of the first tie element is connected to the front side zone of the cap, and a second part of end of the first tie element is connected to the belt structure of the chin strap device.
  • a first part or end of the second tie element is connected to the rear side zone and a second part or end of the second tie element is connected to the belt structure of the chin strap device.
  • tie element is understood as meaning an element which is intended to be tensioned between the belt structure and the portion of the cap to which it is fixed should rotation of the cap occur.
  • the cap comprises a pair of first tie elements, where each of the two first tie elements extends along a respective front side zone, namely along a front, right-hand, side zone and along a front, left-hand, side zone.
  • the cap comprises a pair of second tie elements, where each of the two second tie elements extends along a respective rear side zone, namely along a rear, right-hand, side zone and along a rear, left-hand, side zone.
  • a helmet which comprises at least one first tie element connected, on one side, to the chin strap device and, on the other side, to the cap, in a zone comprised between the chin strap device and the front opening of the cap, so that the at least one tie element may be tensioned so as to oppose rotation of the cap with respect to the user's head.
  • each embodiment forming the subject of the present disclosure may have one or more of the advantages listed above; in any case it is not required that each embodiment should have simultaneously all the advantages listed.
  • the reference number 100 denotes overall a protective helmet according to an embodiment of the present invention.
  • any spatial reference such as “inner”, “outer”, “right”, “left”, “above”, “below” is to be understood as being in relation to the head of a user when wearing the helmet.
  • an inner side of the helmet is a side of the helmet directed towards the head of the user
  • an outer side of the helmet is a side of the helmet directed towards an outer zone opposite to the user's head
  • a zone above the helmet is to be understood as being a zone which, when the helmet is worn, is situated above the user's head
  • a zone below the helmet is a zone which is situated below the helmet when it is worn, and so on.

  • the belt structure is fixed on an inner side of the cap, namely along an inner surface of the cap facing the internal cavity.
  • the belt structure 11 extends between a fixing point on a side portion 117 and a fixing point on the other side portion 118 of the cap 101, crossing a lower region of the helmet 100 where the access zone 121 is located. Even more preferably, in connection with the fixing point, the belt structure 11 is fixed to the side portion 117 of the cap 101 in the vicinity of at least one temple zone of the head of a user wearing the helmet 100.
