Definitions

  • the present invention relates to protective helmets, and in particular to firefighters' helmets.
  • Existing firefighters' helmets comprise a protective outer shell made from impact- resistant plastics or the like which is intended to protect the wearer from falling debris which often is a hazard of burning buildings.
  • the helmet includes a visor and neck protector to protect the head, face and neck of the wearer.
  • a firefighters helmet comprising an inner protective shell configured to be worn on its own as a helmet, and an outer protective shell configured to be fitted over the inner shell and releasably retained thereon, comprising a retaining mechanism for retaining the inner shell in the outer shell, wherein the retaining mechanism is moveable by a user whilst wearing the inner shell between a first position in which the retaining mechanism engages a said shell substantially to prevent relative movement between the two shells and a second position in which the retaining mechanism permits relative movement of the shells whereby allowing the donning or doffing of the outer shell by the users.
  • the outer shell has an outwardly extending brim or cape.
  • the helmet may comprise a spacer for spacing the outer shell from the inner shell.
  • the helmet may comprise a visor which is accommodated between the inner and outer shells when not in use.
  • the retaining mechanism may be releasably biased towards the first position.
  • the retaining mechanism is moveable by a user whilst wearing the inner shell in order to move it from the first to the second position for allowing the introduction or removal of the outer shell onto or off the inner shell.
  • the retaining mechanism may be pivotally connected to the helmet.
  • the retaining mechanism may be pivotally mounted to an attachment mechanism which is connected to the outer shell, the retaining mechanism thereby being spaced from the outer shell.
  • the inner helmet may comprise a slot which is engageable by the attachment mechanism such that when the retaining mechanism is in the second position the attachment mechanism can be moved through the slot whilst when the retaining mechanism is in the first position the attachment mechanism cannot be moved through the slot.
  • the retaining mechanism may engage a lower edge of the slot whilst in the first position.
  • the attachment mechanism may comprise a mounting for an accessory to the helmet.
  • the retaining mechanism may be disposed on the outer shell, in which case it may engage a lower edge of the inner shell.
  • a helmet as described above may comprise a mounting for attaching at least one accessory to the helmet.
  • Figure 1 A shows the outer helmet
  • Figure 1 B shows the inner helmet
  • Figures 2A and 2B show front and side views of the helmet shells assembled together
  • Figure 3 shows an inside view of the inner shell locked into the outer helmet shell
  • Figures 4 to 7 show outer helmet shells with provision for various detachable accessories and ancillary equipment
  • Figure 8 shows schematically an exploded view of a second embodiment of an outer helmet and an inner helmet, having a different attachment mechanism from that of Figures 1 to 3
  • Figure 9 shows schematically a side perspective view of the attachment mechanism for securing the helmets shown in Figure 8
  • Figure 10 shows schematically a front view of the attachment mechanism of Fig 9
  • Figure 11 shows schematically the helmets being attached together
  • Figure 12 shows schematically the attachment mechanism in a locked position
  • Figure 13 shows schematically the attachment mechanism in an unlocked position.
  • Figures 1A and B show a firefighter's helmet comprising separate inner and outer shells.
  • the inner shell of Figure 1B (generally denoted as 10) is wearable on its own as an impact-resisting helmet. It comprises an outer protective moulding 12 of glass fibre- reinforced plastics or other impact-resisting plastics within which is a further impact resisting layer as known per se.
  • the shell 10 is worn by the user by mechanism of a net cap or liner having a headband 14 and chinstrap 16. There is also an ocular protector 18 to protect the firefighter's eyes when only the inner shell is being worn.
  • the outer shell of Figure 1A (generally denoted as 20) comprises a protective moulding 22 of glass fibre reinforced plastics or other impact-resisting plastics material. It has a large enough interior to accommodate the inner shell 10. It also has retaining clips 26 to hold the outer shell onto the inner shell.
  • the outer shell has a full visor 24 to protect the firefighter's face from flying debris and from radiant heat.
  • the visor 24 is pivotally mounted at the sides of the outer shell 20 by mechanism of links 28, 30 pivotally connected to the moulding 22 and the visor 24.
  • the links 28, 30 form a four-bar linkage which enables the visor to move between a deployed position in which it covers the wearer's face, and a stowed position (fig. 2B) in which it is retracted between the inner and outer shells.
  • the use of a four-bar linkage enables the relatively large visor 24 to move along a path close to the surface of the inner helmet. Thereby the outer shell can fit compactly over it.
  • the ocular shield 18 may also be pivotable on a four-bar linkage for storage within the inner shell. However because the shield is shallower, a single-point pivot may suffice.
  • Figures 2A and 2B show a front view of the shells when locked together.
  • the figure shows the outer shell 20 in section and the inner shell 10 in full.
  • Figure 2B shows a side view of the shells locked together with the visor 24 of the outer shell 20 in a stowed position between the two shells (10,20).
  • the rim 32 of the inner shell 12 engages pads (not shown) on the inner surface of the outer shell 22 around the greater part of its circumference, except at the front where a gap is provided to permit the passage of the visor 24.
  • a further pad or pads (not shown) is provided in the comb 34 so that when the outer shell is pulled down on to the inner shell and the retaining clip 26 engaged the outer shell is firmly located on the inner shell with a gap of approximately 6mm between them.
  • each retaining clip 26 is disposed in a housing 27 and biased outwardly by a spring (not shown).
  • the clip 26 can be pressed into its housing 27 in order to allow the inner helmet 10 to slide past the clip 26 into the outer helmet 20.
  • the clip 26 is tapered in such a way that the sliding of the outer helmet onto the inner helmet has the effect of pressing the clip in so that it does not need to be pressed-in manually when the helmets are fully together, the spring returns the clip 26 to a protruding position to hold the shells in place.
  • the orientation of the shells can be seen via the relative positioning of the ocular protector 18 and the visor 24 (which are aligned with each other).
  • a net cap 34 forming the suspension of the helmet on the wearer's head.
  • the net 34 is adjustable as known per so to fit the helmet comfortably to the wearer's head in the correct position.
  • an adjustable nape pad 36 in combination with the chin strap 16 and an adjustable forehead pad 38 locates the helmet-fore-and-aft so that the ocular shield 18 and the visor 24 are properly positioned.
  • Figure 4 shows an embodiment of the helmet which has a slot 40 for mounting breathing apparatus, and an external lever 41 for moving the visor 24 between its stowed and deployed positions.
  • the lever 41 can be omitted.
  • Figure 5 shows a neck curtain 42 attached to the outer shell 20, to provide additional protection against falling ash or embers.
  • Figure 6 shows an embodiment of the helmet which has a mounting for a torch 44.
  • Figure 7 shows a fold out hook loop 46 of the outer shell of the helmet in use to hang the helmet.
  • Figure 8 shows schematically an exploded view of an outer helmet 50, and inner helmet 52 which comprises an inner portion 54, adapted to fit a user's head, and an outer liner 56 to which a visor 58 is attached.
  • An attachment mechanism 60 which connects the inner and outer helmets, is shown in more detail in figures 9 and 10.
  • the attachment mechanism 60 comprises two main portions: a U shaped housing 62 and a lever 64, which is pivotally mounted on the housing at A.
  • a torsion spring (not shown) connects the lever 64 to the housing 62 and biases the lever 64 in a direction which would be clockwise as seen in figure 9.
  • the torsion spring may, alternatively, be formed in the body of the lever 64, particularly if the lever is of a plastics material.
  • the lever 64 comprises an upper portion 66 which is generally rectangular, offset from the midline of, and positioned at a slight angle to a lower portion 68 of the lever 64.
  • the upper portion 66 has a top surface 69.
  • a sloping abutment surface 70 connects one side of the two portions. Due to the biasing of the torsion spring this surface is normally in contact with a raised surface 72 of the leg of the attachment mechanism on which the lever is disposed.
  • the external surface of the leg of the U-shaped housing 62 opposite the lever 64 is glued to an internal surface of the outer helmet 50.
  • the other leg of the housing may be connected to the inner helmet as follows.
  • a slot 74 which is slightly wider than the leg of the U-shaped housing on which the lever 64 is disposed, is formed in the inner portion 54 of the inner helmet 52.
  • the slot is approximately 25 mm long and formed midway between the front and rear of the helmet, around halfway up the helmet's side.
  • a solid abutment surface 76 At the rear of the slot 74 is a solid abutment surface 76, which is as deep as the slot and approximately the same width as the top surface of the lever 64.
  • FIG 11 shows the two helmets during the attachment process.
  • the slot moves upwardly relative to the attachment mechanism, past the pivot point of the lever 64, because it is so narrow it forces the lever to pivot anti-clockwise (as seen in figure 9).
  • the lever snaps back into a position shown in Figure 12.
  • the top surface of the lever 64 now abuts the solid abutment surface 76 of the slot 74, locking the two helmets together.
  • a second attachment mechanism (not shown) is disposed opposite the first attachment mechanism and is its mirror image, being appropriately biased. Both levers must be engaged or disengaged when donning or doffing the helmet.
  • Some other features of the attachment mechanism 60 are shown in Figure 10.
  • the attachment mechanism may have two lugs 80 to which the visor 58, and the liner 56 may be attached, in which case the lowest portion of the leg of the housing to which the lugs are attached may be formed as U-shape to provide a stop for the visor 58.
  • a connector 82 for breathing apparatus may be formed on an external surface of the housing.
  • a firefighter's helmet comprises an inner protective shell configured to be worn on its own as a helmet and an outer protective shell configured to be fitted over the inner shell and releasably retained thereon, comprising retaining mechanism for retaining the inner shell in the outer shell, wherein the retaining mechanism is moveable by a user whilst wearing the inner shell between a first position in which the retaining mechanism engages a said shell substantially to prevent relative movement between the two shells; and a second position in which the retaining mechanism permits relative movement of the shells whereby allowing the donning or doffing of the outer shell by the user.
