Definitions

  • the present invention refers to a (military) helmet configuration, comprising a helmet shell which covers the user's ears partly or completely, having an inside helmet structure arranged to enclose the helmet user's cranium, as well as a chin strap arranged to extend from both sides of the helmet towards the helmet user's chin.
  • Such helmets are of general knowledge.
  • a disadvantage of the known helmet interior structures is that there is no or only limited space for receiving ear muffs, which are provided for protection the user's ears against high sound levels, and which may -instead or additionally- include earphones for communication purposes.
  • a particular problem is that the ear muffs need to be held upon/over the ears under a certain pressure towards the ears for sealing the ear muffs, providing well hearing protection.
  • Known configurations use a separate headset, comprising a bracket and ear muffs at both sides of it.
  • the biggest disadvantage of wearing a helmet in conjunction with ear muffs is that the location on the head directly above the ears is claimed as a support point for the helmet interior as well as a sealing surface for the ear-muffs. With current ear muff designs those two functions can not be combined, without decreasing the helmet stability or causing sound leakage.
  • An other disadvantageous is that the head strap and/or foam pads (forming the inside helmet structure) of the helmet has to be worn over the bracket of the headset, which is not optimal for the fit and stability of the helmet and it is less convenient for the helmet user due to pressure points on the skull. Besides, if a user wants to put on or put off the existing headsets, first the helmet has to be put of, leaving the head unprotected.
  • One aim of the present invention is to provide a helmet configuration including a more compatible set of ear muffs.
  • Another aim is to provide enhanced stability of the helmet by providing that the helmet -via its head strap- rests on the whole cranium of its user without any disruption by a headset bracket.
  • Yet another aim is to provide that the ear muff can applied and removed easily, without the need for putting off the helmet.
  • a helmet configuration comprising a helmet shell, an inside helmet structure, attached to the helmet shell and arranged to enclose the helmet user's cranium, and a chin strap, arranged to extend from both sides of the helmet towards the helmet user's chin, the helmet configuration, moreover, comprising ear muffs arranged for mainly covering the helmet user's ears, wherein said ear muffs are arranged to be in releasable contact with said inside helmet structure and the chin strap during use of the helmet.
  • each ear muff includes protrusive parts arranged to extend under said inside helmet structure and chin strap respectively during use of the helmet.
  • the top side of the ear muff includes a recessed portion, arranged for receiving the inside helmet structure of the helmet, providing that a (soft) seal provided on the ear muffs outer edge facing the user, will cover the area around the user's ear. This way a good seal and a support point can be achieved.
  • Figure 1 shows the head of a user 1, wearing a helmet configuration including a helmet shell 2, a head strap 3 connected (not shown) to the shell 2, part of an inside helmet structure which is arranged to enclose the helmet user's cranium, and a chin strap 4 which is connected to the head strap 3 at three or four connection points, which chin strap 4 further rounds the user's chin.
  • the chin strap 4 may include connecting and or length adjustment means, e.g. buckles, Velcro closures or similar (not shown).
  • Ear muffs 5 are provided, arranged for covering the helmet user's ears 6.
  • the ear muffs 5 are arranged to be releasably connected to the head strap 3 and to the chin strap 4 by means of upper protrusive parts 7 arranged to extend under the head strap 3 and bottom protrusive parts 8 arranged to extend under the chin strap 4 during use of the helmet.
  • Bottom parts 8 include a transverse area 9 for holding the chin strap 4.
  • the helmet configuration includes a compatible set of ear muffs, wherein the proper helmet, via its head strap 3, rests on the whole cranium of its user without being affected by a headset bracket or something like that.
  • the ear muffs 5 can applied and removed easily, without the need for putting off the helmet, viz. by removing the chin straps 4 from the ear muff parts 8 and sliding then the ear muffs 5 downward.
  • the top of the ear muff housing 5 includes a recessed portion 10 which is arranged for receiving the head strap 3 or foam pads (not shown) of the helmet 2 and which provides that a soft seal 11, provided on the ear muffs outer edge facing the user 1, will cover well the area around the user's ear. This way a good seal and a support point can be achieved.
  • An additional cushion 12 is provided between the upper part of the protrusion and the user's head.
  • auxiliary strap 13 is provided interconnecting both ear muff top portions.
  • the ear muff shown in figure 1 is also shown in figure 2 using the same references as in figure 1 . More explicitly shown is the soft seal 11, provided on the ear muff's outer edge facing, in operation, the user 1, which seal 11 is intended to cover well the area around the user's ear.
