Description


[0001] 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.

[0002] In the sector relating to protective helmets it is known to use 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.

[0003] This solution, while being advantageous from many points of view, has a number of drawbacks and in particular has not proved to be sufficient to prevent rotation of the helmet.

[0004] In other words, 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.

[0005] 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.

[0006] This is obtained by means of a helmet as defined in the respective independent claim. Secondary characteristic features are claimed in the dependent claims.

[0007] In particular, 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. In other words, the cap defines an internal cavity intended to accommodate the user's head. Furthermore, 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.

[0008] 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.

[0009] The expression "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.

[0010] "Side portions" is understood as meaning the flanks or sides of the cap, when viewing the cap from a front zone.

[0011] In particular, 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.

[0012] Consequently, when viewing from the front the cap as worn by a user, the access zone is located underneath the cap, and the chin strap device extends underneath the cap between the two flanks of the latter. For the sake of easier illustration it is to be understood that 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.

[0013] 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. In particular, 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. Similarly, 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.

[0014] The expression "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.

[0015] Preferably, 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. Preferably, 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.

[0016] The present disclosure also relates to use of a helmet and a method for protecting the head of a user by means of a helmet according to the respective independent claims.

[0017] Basically, according to the present disclosure, it is possible to provide 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.

[0018] Therefore, the helmet according to the present disclosure is able to solve the problem of rotation of the cap towards the rear zone, also called roll-off, namely the rotation of the cap tending to expose at least partially a frontal zone of the user's head.

[0019] The helmet also comprises a second tie element which is configured to be tensioned in the event of rotation of the cap so as to oppose or prevent rotation of the cap with respect to the user's head, in particular rotation tending to expose during use an occipital zone of the user's head.

[0020] Further advantages, characteristic features and modes of use forming the subject of the present disclosure will become clear from the following detailed description of embodiments thereof, provided by way of a non-limiting example.

[0021] It is in any case clear that 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.

[0022] Reference will be made to the figures of the attached drawings in which:
  • Figure 1 shows a view of a helmet according to an embodiment of the present disclosure;
  • Figure 2 shows a cross-sectional view of the helmet according to Figure 1, in which the tie elements are not tensioned;
  • Figure 3 shows a cross-sectional view of the helmet according to Figure 1, in which the tie elements are tensioned;
  • Figure 4 shows an exploded view of the helmet according to Figure 1;
  • Figure 5 shows a view of a helmet according to an embodiment of the present disclosure when worn by a user;
  • Figure 6 shows a detailed view of the helmet according to Figure 5.


[0023] With reference to the attached figures, the reference number 100 denotes overall a protective helmet according to an embodiment of the present invention.

[0024] In the description below, reference is made to a helmet in the condition when worn by a user. Therefore, for the purposes of simpler illustration, as mentioned above, it is agreed in the context of the present disclosure that 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. Consequently, for example, an inner side of the helmet is a side of the helmet directed towards the head of the user, and an outer side of the helmet is a side of the helmet directed towards an outer zone opposite to the user's head; or 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.

[0025] The helmet 100 is configured to protect the head of a user and comprises a cap 101 and an internal cavity 102, positioned inside said cap 101 and intended to accommodate the head of a user. Furthermore, the internal cavity 102 has an access zone 121, configured to allow access of the user's head inside the internal cavity 102.

[0026] The cap 101 has a front portion 115 defining a front opening preferably connected to the access zone 121, namely in such a way that the front opening and the access zone 121 form preferably a single opening in the cap 101. The cap also has a rear portion 116, opposite to the front portion 115.

[0027] The helmet 100 also comprises a chin strap device 10 comprising in turn at least one belt structure 11, which is fixed between two side portions 117, 118, namely between a right side portion and a left side portion, of the cap 101. In particular, each side portion of the two side portions 117, 118 is comprised between the front portion 115 and the rear portion 116 and the belt structure 11 extends at least between the side portions 117 and the zone 121 for access to the internal cavity 102.

[0028] In particular, preferably the belt structure is fixed on an inner side of the cap, namely along an inner surface of the cap facing the internal cavity.

[0029] Namely, 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.

[0030] Furthermore, a zone of a side portion 117 comprised between the belt structure 11 and the front opening is a front side zone 117a of the cap 101 and a zone of the side portion 117 comprised between the belt structure 11 and the rear portion 116 is a rear side zone 117b of the cap 101. In other words, the belt structure 11 divides the side portion 117 into a front side portion 117a, positioned towards the front opening, and a rear side zone 117b, positioned towards the rear portion 116.

[0031] The helmet also comprises at least one tie element 12a, 12b which extends along the front side zone 117a. In particular, a first part or end of the at least one tie element 12a, 12b is connected to the front side zone 117a of the cap, and a second part or end, preferably opposite to the first end, is connected to the belt structure 11.

[0033] It is to be understood that, in the context of the present disclosure the term "tie element" refers to a preferably ribbon or band or strip like element or an element with any similar form. In particular, a tie element is preferably configured to be tensioned between two points for fixing or connection to other elements of the helmet, for example the belt structure, so as to oppose or prevent rotation of the cap with respect to the head of the user, for example a rotation tending to expose at least partially a frontal zone of the head and/or an occipital zone.

[0034] In other words, during use the belt structure 11 is fixed to the cap 101 in the vicinity of a temple zone of the user's head and is configured to engage with or be coupled with the user's head in a jaw zone so as to keep the user's head inside the internal cavity 102 and therefore prevent removal of the helmet 100. Moreover, during use, the at least one tie element 12a, 12b is associated with the cap 101 in the vicinity of a cheekbone zone of the user and is connected to or fastened or wound around the belt structure 11, so as to be able to engage with it or be coupled to it in order to oppose rotation of the cap 101 with respect to the user's head, in particular a rotation tending to expose during use a frontal zone of the head. The second tie element 13a, 13b operates in a similar manner and opposes rotation of the cap tending to expose during use an occipital zone of the head.

[0035] Preferably, the side portion is a first side portion 117, or right side portion, and moreover the front side zone is a first front side zone 117a and the rear side zone is a first rear side zone 117b.

[0036] In particular, preferably the helmet comprises a second side portion 118, or left side portion, comprised between the front portion 115 and the rear portion 116 and opposite to the first side portion 117. Basically, owing to the geometry of the parts described above, the belt structure 11 extends between the first side portion 117 and the second side portion 118. For example, the first side portion 117 may be right side portion of the cap and the second side portion 118 may be a left side portion of the cap, or vice versa.

[0037] Furthermore, preferably a zone of the second side portion 118 comprised between the belt structure 11 and the front opening is a second front side zone 118a of the cap 101 and a zone of the second side portion 118 comprised between the belt structure 11 and the rear portion 116 is a second rear side zone 118b of the cap 101.

[0038] In particular, moreover preferably the at least one tie element 12a, 12b, namely the first tie element 12a, 12b, is one of a pair of tie elements 12a, 12b, wherein a first tie element of the pair of tie elements 12a, 12b extends along the first front side zone 117a of the cap 101 and the other tie element of the pair of tie elements 12a, 12b extends along the second front side zone 118 of the cap 101.

[0039] Namely, preferably each tie element 12a, 12b of the pair of tie elements 12a, 12b is connected to the respective front side zone, for example right or left side zone, and is furthermore connected to the belt structure in the respective side portion of the cap 101.

[0040] In other words, preferably each of the pair of tie elements 12a, 12b is associated with the cap 101 in the vicinity of the respective cheekbone zone of the user's head, for example in a right or left zone of the cap.

[0041] Preferably, the at least one second tie element 13a, 13b is configured to be tensioned in the event of rotation of the cap 101 so as to oppose or prevent rotation of the cap 101 with respect to the user's head, in particular a rotation tending to expose during use an occipital zone of the user's head.

[0042] Preferably, the pair of tie elements 12a, 12b is a pair of first tie elements 12a, 12b and the at least one second tie element 13a, 13b is one of a pair of second tie elements 13a, 13b. In particular, a first tie element of the pair of second tie elements 13a, 13b extends along the first rear side zone 117b of the cap 101 and the other tie element of the pair of tie elements 13a, 13b extends along the second rear side zone 118b of the cap 101. For example, the first rear side zone 117b is one of a rear, right, side zone and a rear, left, side zone of the cap, while the second rear side zone 118b is the other one of a rear, right, side zone and a rear, left, side zone of the cap.
