Definitions

  • the present disclosure relates generally to the technical field of protective helmets. More particularly, the present disclosure relates to an inner liner, conventionally also referred to as "interior”, for a protection helmet, which is located inside an external cap of a helmet, and intended to be interposed between the cap and a user's head.
  • an inner liner conventionally also referred to as "interior”
  • a protection helmet which is located inside an external cap of a helmet, and intended to be interposed between the cap and a user's head.
  • inner liner of a helmet it is meant a generally soft assembly which is for covering, at least partially, an internal or concave side of the cap (wherein said cap includes a shell and a polystyrene layer) and acting as soft layer or comfort layer between the cap and the head.
  • inner liner can also comprise cheekbone guards.
  • the external cap conventionally made up of a shell and a polystyrene layer, has a substantially spherical shape, with a variable internal circumference depending on the head size or dimension.
  • the liner has a predefined height depending on the internal circumference of the cap, and is such as to fill a gap between the internal circumference of the cap and the circumference of a user's head.
  • the inner liner has a height depending on the difference of the average dimensions of head circumference and internal diameter of the cap, to fill the space between the rigid external cap and the head.
  • a drawback is, e.g., that with a known inner liner it is not always possible to provide an optimal comfort and at the same time stability to the helmet.
  • the technical problem at the basis of the present disclosure lies in providing an inner liner of a helmet and a helmet including such liner allowing to overcome at least one of the drawbacks mentioned hereto and/or providing some advantages.
  • Such a technical problem is solved by an inner liner for helmets as defined in the independent claim 1 and by a helmet according to claim 8.
  • the present invention also relates to a method for customizing an inner liner for helmets, as defined in claim 12.
  • a pad which lines the cap and includes at least two overlapped layers wherein a second layer is at least partially overlapped to the first layer only limitedly to defined zones of the external cap (more precisely of the polystyrene layer) resting on the head it is given the option of customizing the inner liner on the basis of certain needs, e.g. of anatomical nature, or for the aims to which the helmet is intended or for further contingent needs.
  • the customizing of the inner liner can be enhanced depending on the cap resting/comfort needs, and the pad stratification can be differentiated according to head zones.
  • the inner liner according to the present disclosure allows to use, for a given range of sizes, a single cap of standard dimension, and vary the inner liner, customizing the inner liner on the basis of the size, or of a specific configuration of a user's head. In this regard, it could suffice to vary the two or more layers forming the pad.
  • the pad is a multilayer structure with layers having thickness and/or differentiated material according to head zones.
  • the inner liner is a sandwich structure including a first lining, a second lining, and the pad is included between the first lining and the second lining.
  • the helmet 12 includes a rigid external cap 14, which includes a polystyrene layer 15 and a shell 17 of reduced thickness with respect to the polystyrene layer 15.
  • the inner liner 10 is adapted to be interposed between a user's head T and the cap 14. Therefore, such inner liner 10 is a generally soft structure intended to be bent to adhere to the shape of a user's head T.
  • the inner liner 10 is fixed to the cap 14, e.g., by Velcro® snap fasteners or alike removable fixing means.
  • the inner liner 10 includes a pad 24 made of a soft and spongy material that partially lines the cap 14 and has open zones or cavities 26, allowing to keep the overall weight of the helmet 12 as reduced as possible, as well as facilitating aeration inside the helmet 12, or allowing ear accommodation.
  • the pad 24 includes appendages 27 which extend to the region of each cheekbone and mandible of a user, to form so-called cheekbone guards.
  • the pad 24 comprises at least two layers, i.e. a first layer 124 facing the user's head T and a second layer 224 facing the cap 14.
  • the second layer 224 is at least partially overlapped to the first layer 124 limitedly to defined zones of the first layer 124, e.g. in zones intended to support the polystyrene layer 15 of the rigid cap 14.
  • the second layer 224 is only confined to some zones of the liner 10, in which the rigid cap 14 rests on the head T.
  • the second layer 224 is a layer which has a surface extension smaller than the first layer 124, so as to create a localized support zone for the rigid cap 14.
  • the first layer 124 is different from the second layer 224 by thickness or height, and/or by material.
  • the pad 24 is a mat having two or more layers at least partially overlapped, which are mutually different in thickness or height, and/or in material.
  • the first layer 124 is made of a material having a compressive strength smaller than the material of which the second layer 224 is made.
  • the first layer 124 is made of a material having a compressive strength smaller than the material of which the second layer 224 is made.
  • the two layers 124, 224 may be made of foam, gel, polyurethane or polystyrene.
  • the inner liner 10 is a textile sandwich structure including a first lining 20, or external leather, a second lining 22, or internal leather, and the pad 24 of spongy material, included between the first lining 20 and the second lining 22.
  • the pad 24 forms an inner core or kernel for the sandwich structure.
  • the first lining 20 and the second lining 22 are perimetrically connected in the region of respective edges projecting with respect to the core or pad 24, optionally by an edge ribbon, to keep the pad 24 stationary.
  • the first lining 20 and the second lining 22 are made of a so-called comfort fabric, e.g. of microfiber or of Lycra.
  • the inner liner 10 can be adapted by modifying the number of layers 124, 224 forming the pad 24, or the material or the related thickness of each layer with which the pad 24 is manufactured, according to the zones that such layers occupy on the head.
  • the inner liner 10 comprises one or more support inserts 25 inserted into corresponding holes 33, in the example pass-through holes, obtained in the pad 24, and therefore in both layers, and in the first lining 20.
  • the support inserts 25 have a further supporting or resting function, i.e. are able to support the cap 14 in the region of defined zones of the cap 14 resting on the head T.
  • the inner liner 10 includes a pad 24 of spongy material and support inserts 25, them also preferably made of spongy material, preferably having a compressive strength greater than the material of which the pad 24 is made, so as to act as further support for the cap 14 of the helmet 12.
  • the position of the support inserts 25 can be selected on the basis of a shape of the user's head T (for example on the basis of the dimensions or peculiar anatomical features), actually freeing from a direct or strict correlation the dimensioning of the cap 14 and a user's dimension or head.
  • the support inserts 25 act as spacers so that the cap 14 keeps at a certain distance from the head T.
  • the support inserts 25 are made of a flexible cell structure such as, e.g., of foam.
  • the support inserts 25 are made of gel, polyurethane, polystyrene.
  • four support inserts 25 are provided, arranged in the region of as many four points on the top of a user's head T, in particular two aligned in a top front zone ( Figure 2 ) and two aligned in the top rear zone ( Figure 3 ).
  • the support inserts 25 or wedges have a cylindrical shape and are provided with internal pass-through holes 28 parallel to the cylinder axis.
  • the inner liner 10 is manufactured according to the following process.
  • the first lining 20 and the second lining 22 are provided, cut in a pattern according to the profile of inner liner 10 to be obtained.
  • the layers 124, 224 of the various materials forming the pad 24 are inserted between the first lining 20 and 22.
  • the layers 124, 224 and the first lining 20 are provided with respective holes 33 for housing the support inserts 25.
  • first lining 20 and the second lining 22 are provided on the inner side with a film of glue, schematically drawn and denoted by reference number 120 in figure 8 , and are placed under a press 60 to foster adhesion and mutual gluing.
  • a film of glue schematically drawn and denoted by reference number 120 in figure 8
  • the pad 24 formed by the various layers and materials described is immobilized between the first lining 20 and the second lining 22.
  • the first lining 20 and the second lining 22 have a surface extension greater than the pad 24.
  • perimetrical portions of the first lining 20 and of the second lining 22 are stably connected to each other, e.g. by glue or adhesive, along the entire perimetrical edge so as to contain the pad 24.
  • the first lining 20 and the layers 124 and 224 are moreover provided with holes 33 for the housing of the support inserts 25.
  • the edge is subsequently trimmed and an edge ribbon is added.
  • This process for manufacturing the inner liner 10 allows to modify the materials and the layers of the pad 24 according to the needs, like e.g. according to the type of a protective helmet, e.g. motorcycle helmet, bicycle helmet, ski helmet, climbing helmet or other helmets as well as to vary at will the design of the inner liner.
  • a protective helmet e.g. motorcycle helmet, bicycle helmet, ski helmet, climbing helmet or other helmets
  • the pad 24 can be modified in a customized and localized manner, e.g. by modifying the layer 224, according to the shape and size of a user's head.
