Abstract

The invention relates to a helmet, in particular a protective helmet for emergency services or intervention forces. Said helmet comprises a dome (1), which is provided with internal padding and lateral convex sections (1 a) in the ear regions for accommodating ear defender capsules (5). The dome (1) and the lateral convex sections (1 a) in the ear regions consist preferably of a single deep-drawn titanium sheet.

Description

  • The invention concerns a helmet, in particular a protective helmet for operational services, comprising a helmet dome provided with internal padding, wherein the helmet dome in the ear region has lateral outward bulge portions for receiving ear defender capsules. Helmets of that kind are preferably used as police helmets and are intended to be bullet-proof to protect the user. Known helmet domes involve a multi-layer composite. The material used was in particular Kevlar which however causes problems in the edge region of the helmet dome.
  • The object of the invention is to provide a helmet which is desirable in regard to bullet-proofness and weight.
  • In accordance with the invention that is achieved in that the helmet dome together with the lateral outward bulge portions in the ear region comprises a, preferably one-piece, deep-drawn titanium sheet.
  • The deep-drawn titanium sheet which is used in accordance with the invention is distinguished by being of comparatively low weight and being highly bullet-proof. The one-piece deep-drawn production of the helmet dome makes it possible to avoid welded seams which are critical from the point of view of being bullet-proof and which are complicated and expensive in terms of manufacture.
  • A preferred embodiment of the helmet according to the invention has cheek protection regions which are drawn forwardly from the lateral outward bulge portions in the ear region. That provides that the bullet-proof characteristics are also improved when under fire from the side in the cheek region, in comparison with previous helmet structures. It is particularly desirable that the closed visor—seen from the side—covers the cheek protection region without any gap.
  • A variant of the invention provides that the ear defender capsules are mounted internally movably to the helmet dome. In that arrangement a spring can press the ear defender capsules against the head of the user in the condition of use. For fitting and removing the helmet it is possible to provide a displacement device—most advantageously a strap with which the ear defender capsules are movable away from the head of the user.
  • Further advantages and details of the invention will be described more fully with reference to the specific description hereinafter.
  • FIG. 1 shows a diagrammatic front view of an embodiment of a helmet according to the invention, wherein the visor mounting and the fixing screw for the ear defender mask on the one hand and the displacement strap for the ear defender capsules on the other hand are not shown,
  • FIG. 2 also shows a front view but with the pivotably mounted closed visor,
  • FIG. 3 shows a side view with a closed visor,
  • FIG. 4 shows a side view with an open visor,
  • FIG. 5 shows a view in cross-section through the left-hand half of an embodiment of a helmet according to the invention, in which the ear defender capsule is moved towards the helmet dome by a displacement device, and
  • FIG. 6 shows a view in cross-section through an embodiment with a fabric liner.
    •
  • The helmet shown in FIGS. 1 to 4 can be used in particular as a protective helmet for operational or emergency services (for example police).
  • In the ear region the helmet dome 1 has lateral outward bulge portions 1 a which are provided for receiving ear defender capsules 5 which are described in greater detail with reference to FIG. 5. The position of the ear defender capsules 5 is shown in broken line in FIG. 3.
  • According to the invention the helmet dome 1 together with the lateral outward bulge portions 1 a in the ear region comprises a deep-drawn titanium sheet which is preferably in one piece. In the illustrated embodiment the helmet dome 1 is of a single-layer configuration and involves a sheet thickness of between 2 mm and 4 mm, preferably about 3 mm. Those dimensions affords an optimum compromise between bullet-proofness on the one hand and weight on the other hand.
  • The helmet dome 1 can be free from welded seams by virtue of the one-piece, deep-drawn configuration of the titanium sheet.
  • Although in principle titanium alloys are also appropriate, it is preferably provided that the helmet dome comprises pure titanium, with the proportion of titanium being over 99%.
  • As in particular FIGS. 1 and 4 show, in the illustrated embodiment of the helmet according to the invention the helmet dome 1 is drawn forwardly on both sides, starting from the lateral outward bulge portions 1 a in the ear region, to form cheek protection regions 1 b, wherein the two cheek protection regions 1 b are in one piece with the remainder of the helmet dome 1. That makes it possible to achieve increased bullet-proofness from the side.
  • In a particularly preferred embodiment of the invention the helmet has a pivotably mounted visor 2 which in the closed condition laterally covers the foremost portion of the cheek protection regions 1 b, as can be seen in particular from FIG. 3. The visor 2 can be pivoted upwardly about pivot mountings 3 in per se known manner (see FIG. 4).
  • In accordance with a further preferred configuration of the invention which is illustrated in FIG. 5, the ear defender capsules 5 are mounted movably to the helmet dome 1. The illustrated embodiment has a spring device which is formed by a leaf spring 4 and which carries the ear defender capsules 5. The leaf spring 4 is fixed at the top to the pivot mounting 4 for the visor 2 at the inside of the helmet dome 1 and carries the ear defender capsules 5 in the region 6. The leaf spring 4 is biased in the direction of the centre of the helmet (arrow 7).
  • In order to make it easier to put on and remove the helmet the embodiment of FIG. 5 has a displacement device 8 in the form of a flexible strap, which is passed around the lower edge 1 c of the helmet dome. The strap 8 is joined (for example riveted) to the leaf spring 4 at the location 9. That connecting location can be covered by way of a shrink tube 10 in order to avoid injury due to the sharp-edged end of the spring. Near the free end 8 a of the strap 8 a loop-like or eye-like holding device 9 is joined to the strap by way of which the strap can be engaged into the groove 10 of the holder 11. In that way the ear defender capsule 5 can be moved against the force of the leaf spring 4 relative to the helmet dome 1 into the fitting and removal position shown in FIG. 5, and held in that position. When the strap 8 is disengaged from the holder 11 the leaf spring 4 urges the ear defender capsules 5 in the direction of the arrow 7 snugly against the ear region of the person wearing the helmet. The holder 11 can serve at the same time as a holder for a breathing mask.
  • FIG. 6 diagrammatically shows a further embodiment in which at least one fabric liner of a high-strength ballistic fabric is arranged at the inside of the helmet dome 1 to enhance the ballistic resistance. That can involve for example aramid fabric (Kevlar or Twaron) and/or PE fabric and/or UD material. The term UD material is used to denote a unidirectional material in which the individual fibres are not woven but are fixed in a carrier material (matrix) parallel and cross-wise in mutually superposed relationship.
  • The fabric liner which can also be of a multi-layer configuration is pressed into the helmet dome or glued in place in pressure-less fashion. The join between the liners or between the fabric and the titanium of the helmet dome is made by means of resin or suitable adhesive. The fabric liners can be tailored to adapt them to the shape of the helmet dome.
  • It will be appreciated that the invention is not limited to the illustrated embodiments. It is also to be mentioned that the usual internal padding has not been illustrated, for reasons of clarity of the drawing.
