Definitions

  • the invention relates to a helmet with a hard outer shell and a shock-absorbing insert dome, which abuts the outer shell with closely located elevations.
  • Such a helmet is known from German utility model 1 683 479.
  • a strap construction that was usual in the past is provided, which keeps the head away from the outer calotte.
  • an insert dome made of shock-absorbing material is provided, which can be wave-shaped on its surface facing the outer dome or can have wart-like elevations. This should increase the suspension properties of the insert dome.
  • domes made of polystyrene have been used for many years. They lie directly on the outer shell of the helmet with a smooth surface and are regularly glued there.
  • the invention has for its object to improve the shock absorption properties of the insert dome, in particular a Solgeschaumtem Chen with a dome / polystyrene.
  • the elevations of the spherical cap are formed by a layer of knobs placed on the spherical cap body, which consists of a material which is different from the spherical cap body and allows the plastic deformation of the knobs under strong pressure.
  • the spherical cap according to the invention consists of a spherical cap body with a smooth outer surface and a knob layer arranged thereon made of a different material than the spherical cap body.
  • This structure has the advantage that the spherical cap body and the knobbed layer can perform various shock absorption tasks.
  • the elastic property of the spherical cap is used for light impacts in order to absorb most of the impact energy.
  • the material of the knobbed layer is chosen so that such impacts are transmitted from the outer shell to the calotte body. Only with very strong impacts
  • the opposing layer has a shock-absorbing effect by elastically deforming the knobs. If, in a preferred embodiment, the diameter of the knobs decreases towards the free upper end, the energy absorbed by the deformation of the knobs increases with increasing deformation.
  • the knobs are preferably formed so that their height is greater than their diameter, preferably the height is approximately twice the diameter.
  • a design which has proven itself in practice has knobs with a height of approx. 4 mm and a diameter of approx. 2 mm, for example 1.5 mm.
  • the nubs of the nub layer are preferably distributed in such a way that the clear space between the nubs is larger than their diameter.
  • the knobs are all equally and evenly distributed. This makes it possible to use a pimple layer that is not specially prepared for the helmet, which can either be brought into the shape of the helmet by heat deformation or is applied to the dome body in several parts in the form of a web.
  • the preferred sheet-like arrangement of the knobbed layer has the advantage that it does not need to be preformed and can be made from flat sheet material. This means that when the knobbed layer is adapted to the calotte body in question, there can be no irregular shapes which would impair the comfort of the helmet.
  • the web-shaped material is preferably connected to the calotte body by gluing.
  • the pimple layer should be provided essentially in the area of the upper skull shell.
  • the nub layer in the area of the neck and chin part can be omitted.
  • a helmet which consists of a hard outer shell 1, which is provided towards the interior with a shock-absorbing insert dome 2. There is a face opening 3 on the front of the helmet.
  • the insert dome 2 consists of a conventional dome body 3, for example made of styrofoam.
  • a knob layer 4 is glued to the calotte body 3, which is smooth on the inside and outside, which is preferably formed from a high-pressure polyethylene.
  • the knobbed layer lies on the smooth outside of the calotte body 3 with a smooth underside.
  • the knobs 5 of the knob layer 4 are directed towards the outer shell 1. Their diameter decreases continuously towards the outer shell 1.
  • the distribution of the knobs 5 is such that the clearance Z is larger than the diameter D of the knobs 5.
  • the knobs are 4 mm high and the diameter is 1.5 mm.
  • the nub layer 4 is formed in Figure 1 from a plurality of webs which are cut out of a flat material.
  • a middle path extends from the forehead area of the helmet over the crown to the neck area.
  • Figure 1 shows a section through this path.
  • the remaining side areas are formed by corresponding pieces, also cut out from flat material.
