Definitions

  • the present invention relates to an innovative padding for personal protective means such as, for example, protective helmets for motorcycles, bicycles, scooters or push scooters, etc.
  • the padding object of the present invention is able to guarantee perfect comfort to the user thanks to the fact that it is floating with respect to the inner surface of the helmet itself.
  • a personal protective helmet will be taken as an example.
  • the helmet is a protective headgear, part of the personal protective equipment made of impact-resistant material and used both in sports and in the world of work, with the aim of protecting the head from sudden impacts.
  • sports that require the use of personal protective equipment such as a helmet: cycling, motorcycling, car racing, skiing, snowboarding, skating, skateboarding, equestrian activities, American football, baseball, rugby, climbing, etc. but also many industrial sectors, such as: construction, steel, manufacturing, etc.
  • the helmet generally includes: an external shell or shell, rigid and made of plastic or composite material, an inner energy-absorbing layer of polystyrene and an inner padding in contact with the user's head.
  • the main contact points of the helmet, once worn, are precisely those where the inner padding is present: the forehead, the temples and the back of the head, in direct contact with an inner layer of shock absorption of the helmet itself.
  • the present invention aims to create a helmet with an innovative padding in order to obtain greater breathability of the user's head by means of a cavity positioned between the padding and the inner surface of the helmet on which this padding is hooked up. This also allows you to keep the helmet padding cleaner without having to constantly wash it.
  • the helmet provided with padding according to the present invention is configured to ensure maximum breathability during use, as specified in the attached independent product claim.
  • FIG. 1 schematically illustrates a cross section of a helmet including the padding according to an embodiment of the present invention
  • FIG. 1 illustrates the inside of the helmet in Figure 1 with the assembled padding
  • FIG. 3 illustrates the padding in an unassembled configuration.
  • the helmet 10 includes an external shell 1 or shell, rigid and made of plastic or composite material, an inner layer 2 of energy absorption made of polystyrene and an inner padding 3 in contact with the user's head.
  • the inner padding 3 and the inner layer 2 of energy absorption of the helmet 10 are separated by a gap 6 within which the air can freely circulate and thus guarantee adequate ventilation inside the helmet and consequently on the user's head. Therefore, the inner padding 3 does not adhere to the inner layer 2 but is floating with respect to it.
  • the inner padding 3 can be represented graphically as an arc of a circumference with center C and radius r; similarly, the inner layer 2 of energy absorption can be represented graphically as an arc of a circumference with center C and radius r'.
  • the inner padding 3 and the inner layer 2 must be such that the ratio between the radius r of the inner padding 3 and the radius r' of the inner layer 1 are linked by the following ratio: 1.10 r ' ⁇ r ⁇ 1.20 r'.
  • the circumferential arc describing the padding must have a radius r greater than the radius r' of the circumferential arc describing the arc of the inner layer 2. This increase is effective if between 10% and 20%. Lower increases would not guarantee sufficient breathability, while higher increases would make the helmet difficult to wear as it would leave a significant portion of the user's head uncovered.
  • the inner layer 2 of energy absorption includes at least one attachment/ release hole 8 for the padding 3 of a personal protective helmet 10.
  • the at least one attachment hole 8 is integrated into the inner layer 2 of energy absorption of the helmet 10 via co-molding or thermoforming.
  • the hooking/release devices 4 of the padding 3 are configured to be inserted into corresponding hooking/release holes holes 8 in the inner layer 2 of the personal protective helmet 10.
  • the padding 3, as illustrated in Figure 3 includes: an element made in flexible plastic 5 integrated in a layer of polyurethane covered in fabric, in direct contact with the user's head, a fastening portion 7 of the covering element 5 made of rigid plastic and means for hooking/release 4 the padding 3 to the inner layer 2 of energy absorption of the helmet 10.
  • the hooking/release devices 4 of the padding 3 to the inner layer 2 of energy absorption of the helmet 10 can be, for example, small buttons, inserts, buttonholes, etc.
  • the number of hooking/release devices 4 of the padding 3 inside a helmet 10 is greater than or equal to four to allow adequate stability of the padding itself.
  • the padding 3 can take on almost two-dimensional or three-dimensional shapes with constant thickness along its entire surface. This feature allows for greater comfort once the personal safety helmet is worn, since all points of contact with the user's body have constant thickness and therefore allow perfect adhesion.
