Definitions

  • the present disclosure relates in general to the technical sector of protective helmets. More particularly, the present disclosure relates to cheek pads for protective helmets.
  • the protective helmet may be particularly suitable for dynamic activities and sports such as motorcycling, skiing, horse-riding, cycling, motorcycling, American football and other similar sports where the use of a protective helmet is required.
  • helmets comprise a cap-like shell formed by an outer shell of rigid plastic material and an inner layer of polystyrene or other material configured to absorb an impact or knock.
  • the outer shell has mainly an anti-penetration function, while the inner layer has an impact energy absorbing function.
  • the known helmets comprise a soft inner layer, generally composed of one or more inserts, intended to provide a sense of comfort for the user.
  • This soft inner layer generally comprises so-called cheek pads which are positioned opposite the user's cheeks and the so-called “neck roll” which is instead positioned in a rear zone of a user's head.
  • the cheek pads consist of a pair of cushions of suitable shape which are intended to be positioned on the right-hand and left-hand sides of a user's face, in particular between the layer of polystyrene of the helmet and the user's face.
  • the neck roll is instead usually U-shaped or C-shaped and is positioned so as to surround at least partially a rear bottom portion of a user's head.
  • the neck roll may extend also towards a top zone of a user's head.
  • each insert is provided with fastening elements for removable connection of the cheek pad to a remaining helmet portion, for example to the inner layer of polystyrene or directly to the rigid shell.
  • said fastening elements consist of one or more snap buttons for each soft inner insert and a plastic portion configured to be interposed between the rigid shell and the polystyrene layer.
  • each insert generally includes at least one first button portion which is configured to be joined together with a second button portion located, for example, on the inner polystyrene layer of a helmet.
  • the known fastening elements make difficult or complicate the operations of joining the insert to a remaining portion of the helmet, for example following washing of the said insert.
  • the snap buttons make the operations of fastening an insert of the helmet to a remaining portion of the said helmet particularly difficult.
  • a same insert comprises a plurality of fastening buttons for ensuring a better connection between the said insert and the remaining portion of the helmet, for example the inner polystyrene layer.
  • the closing or connection of the other buttons is particularly complex or awkward.
  • a further drawback of the known fastening elements consists in the fact that the snap buttons do not ensure a stable and reliable connection between an insert and a remaining portion of the helmet. In fact, movements of the head inside the helmet and/or repeatedly putting on and taking off a helmet may result in less efficient engagement between the insert and a remaining portion of the helmet.
  • fastening elements such as snap buttons do not ensure optimum isolation of the interior of the helmet with respect to the external environment and favour, for example, the diffusion of noise also inside the helmet which may disturb and/or trouble a user.
  • the present disclosure proposes providing a helmet padding which is able to overcome the drawbacks mentioned above with reference to the prior art and/or achieve further advantages.
  • the helmet padding according to the present disclosure comprises a cushioning body and a component of a coupling device configured to removably connect the cushioning body to a remaining helmet portion.
  • the component associated with the padding forms part of a coupling device which allows a reversible connection of the said padding with a remaining portion of a helmet, for example with an inner layer of polystyrene or with the shell of the helmet itself.
  • the component of the coupling device which is associated with the helmet padding comprises one of the sliding element and a sliding guide.
  • the sliding element comprises a head and a stem
  • the sliding guide comprises a seat with at least one insertion terminal mouth and a longitudinal opening.
  • the latter is configured to allow passage of the stem of the sliding element and insertion of the head of the sliding element itself via the insertion terminal mouth.
  • the insertion terminal mouth is open at the end in an insertion direction to allow insertion of the head in the sliding direction.
  • the longitudinal opening is further configured to prevent the head of the sliding element from coming out of the longitudinal guide.
  • the sliding guide is configured to constrain the sliding element and prevent the movement away from each other of the sliding guide and the sliding element.
  • the sliding guide allows sliding of the sliding element inside the seat along a sliding direction and prevents separation of the sliding element from the guide in a direction different from said sliding direction.
  • the sliding element is slidably engageable inside the sliding guide.
  • the padding according to the present disclosure may be easily coupled to a remaining helmet portion by means of an insertion starting from the terminal mouth. Moreover, compared to conventional coupling elements, it ensures a more effective, or tighter, connection to the remaining helmet portion and allows the noise to be reduced inside the helmet itself.
  • the component of the coupling device is sewn to the cushioning body.
  • the sliding element or the sliding guide is associated with the cushioning body of the helmet padding by means of stitching.
  • the component of the coupling device is firmly fastened to the padding, in particular to the cushioning body of the padding. As a result, it is possible to obtain effective coupling together of the padding and the remaining helmet portion.
  • the sliding guide comprises an abutment element configured to define the longitudinal opening and prevent, during use, the head from coming out of the longitudinal opening, in a direction orthogonal to a sliding direction.
  • the insertion terminal mouth and said sliding guide define a sliding direction and the terminal mouth is open in said sliding direction to allow said insertion of the head of the sliding element starting from said mouth. Consequently, during use, the helmet padding is effectively associated with the remaining helmet portion.
  • the abutment element prevents the movement away, or separation, of the padding itself from the remaining helmet portion, but a longitudinal insertion is not prevented.
  • the coupling device includes, or is associated with, an impedance element designed to prevent further relative sliding of the sliding element and the sliding guide. In practice, once inserted into the sliding guide starting from the terminal mouth, there is an impedance element or other blocking device to prevent further sliding or a coming out of the sliding element from the guide.
  • the coupling device is a first coupling device.
  • the padding according to the present disclosure comprises a second component of a second coupling device of the male-female type configured to couple, or connect, removably the cushioning body to a remaining helmet portion.
  • the helmet padding comprises a male element or a female element of a coupling device of the male-female type for further coupling the cushioning body of the helmet padding to a remaining helmet portion.
  • the coupling together of the helmet padding and a remaining helmet portion is further improved.
  • the helmet padding comprises two components of two different coupling devices.
  • the padding is further fastened to the remaining helmet portion by means of a second coupling device.
  • the second removable coupling device is a snap button.
  • the first coupling device comprises a ring element.
  • This ring element is configured, during use, to be interposed between a male element and a female element of the second coupling device. Consequently, during use, the ring element of the first coupling device is configured to prevent relative sliding of the sliding element and the sliding guide of the first coupling device itself.
  • the ring element interposed between the male portion and the female portion prevents, during use, a relative movement of the padding and the remaining helmet portion. It can be understood that, in this embodiment, the ring element acts as the aforementioned impedance element.
  • the present disclosure also relates to a helmet comprising a helmet padding, according to anyone of the above-described embodiments and preferred aspects.
  • the helmet comprises the other one of the sliding element and the sliding guide.
  • the helmet according to the present disclosure comprises a padding which comprises a sliding element or a sliding guide, while the helmet with which said padding is associated comprises the other one of the sliding element and the sliding guide.
  • said other one of the sliding element and the sliding guide is associated with a layer of the helmet configured to absorb energy.
  • the component of the coupling device associated with the helmet is associated with the layer configured to absorb energy of the helmet, for example a layer on the inside of a shell of helmet, for example a polystyrene layer.
  • the remaining helmet portion is a layer of the helmet itself, configured to absorb energy.
  • the remaining helmet portion may be a rigid shell of said helmet.
  • the present disclosure also relates to a method for coupling a helmet padding to a remaining helmet portion.
  • This method involves sliding a sliding element of a coupling device inside a sliding guide of the said coupling device, that is in a sliding direction.
  • one of the sliding element and the sliding guide is associated with the helmet padding, while the other one of the sliding element and the sliding guide is associated with the remaining helmet portion.
  • this remaining helmet portion is a layer configured to absorb energy.
  • the remaining helmet portion is a rigid shell of said helmet.
  • the coupling device is a first coupling device and the method comprises the further step of coupling by means of a second coupling device of the male-female type the helmet padding to the remaining helmet portion.
  • the efficiency of coupling together of the padding and the helmet is further improved.
  • the sliding element is inserted in a sliding direction in the sliding guide starting from an insertion terminal mouth which is open in said sliding direction, so as to facilitate the coupling of the padding with the remaining portion of the helmet.
  • the method involves the further step of inserting, or arranging, a ring element of the first coupling device between a male portion and a female portion of the second coupling device.
  • the ring element is configured, during use, as said above, to prevent relative sliding of the sliding element and the sliding guide.
  • said insertion step is carried out before the step of coupling the second coupling device.
  • each embodiment of 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.
  • Other advantages, characteristics and methods of use of the object of the present disclosure will become evident from the following detailed description of some of its preferred embodiments, given by way of example and not of limitation.

  • every spatial reference such as inner, outer, right-hand, left-hand, above or below is to be understood as referring to the head of a user when wearing the helmet. It follows that, 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 the user's head; or a zone at the top of the helmet is to be understood as being a zone which, when the helmet is worn, is located above the user's head.
  • the padding 100 comprises a cushioning body 101 configured to provide a sense of comfort for the user when wearing a helmet with the padding 100.
  • the padding 100 comprises furthermore a component of a coupling device 10 configured to removably connect the cushioning body 101 to a remaining helmet portion.
