Definitions

  • the invention relates to a bulletproof helmet consisting of a bulletproof dome and an interior, which is attached to the dome with a screw-sleeve connection, which protrudes through an opening of the dome and on the outside of the dome with a trained to rotate by a tool flat, round head.
  • Bulletproof helmets usually consist of a steel dome or, for reasons of weight, preferably a plastic dome consisting of a large number of plastic layers reinforced with fabric layers.
  • a common interior of such helmets consists of a strap and a shock-absorbing plastic basket, which preferably consists of spider-like webs on which there are shock-absorbing knobs.
  • this interior is attached to the bulletproof dome by means of a screw-sleeve connection, which is inserted in a corresponding hole in the helmet, a head of the connection abutting the outside of the dome and preferably having a spherical surface with a has a low overall height.
  • the head can belong to a screw if an associated sleeve with an internal thread is connected to the interior, so that by screwing the screw in the sleeve a firm connection between the calotte and interior can be produced.
  • the head is provided with a small hexagon socket and can be held securely with a suitable hexagon wrench.
  • the screw with the head resting on the outside of the spherical cap is usually made of steel, while the sleeve can consist of a conventional brass alloy.
  • a similar helmet is known from US-A-2 802 212, but the head which can be rotated by means of a tool is located on the inside of the calotte.
  • the present invention is based on the general problem of improving the bullet resistance of such a known helmet.
  • a bulletproof helmet of the type mentioned is characterized according to the invention in that the head with the associated part of the screw-sleeve connection is made of solid, flat surface made of a high-strength material and is provided with parallel, opposite straight edges as a key surface .
  • the invention is based on the surprising finding found by the applicant that the screw-sleeve connection of the known helmet is a weak point with regard to the bullet resistance, which unexpectedly has a lower bullet resistance than the known multi-layer helmet caps made of plastic. It has been shown in tests that if the screw-sleeve connection is bombarded directly, parts of this connection are catapulted into the interior of the helmet and therefore pose a life-threatening risk of injury to the helmet wearer. It has been shown in the investigations by the applicant that a weak point in the screw-sleeve connection lies in the design of the hexagon socket.
  • the high-strength material of the head with the part of the screw-sleeve connection connected to it is preferably high-strength steel of strength class 8.8 (yield strength, tensile strength).
  • the bullet resistance of the screw-sleeve connection can be increased by the inventive design of the head so that it regularly exceeds the bullet resistance of conventional bulletproof caps and therefore no longer represents a weak point for the protection of the helmet wearer.
  • Figure 1 shows the front part with the transition into the neck part of a bullet-proof dome 1.
  • a head 2 of a screw 3 can be seen, which projects through a suitable bore 4 in the cap 1.
  • the head 2 has a spherically convex outer surface 5 with a circular outer edge 6.
  • the outer edge is formed by two parallel straight edges 7, which represent key surfaces for holding the head 2 in a rotationally fixed manner.
  • the screw 3 together with a suitable sleeve 8 with an internal thread for the screw 3, forms a screw-sleeve connection 3, 8 through the spherical cap 1.
  • the sleeve 8 is also provided with a head 9 which has a hexagon socket 10 with which the sleeve 8 can be tightened on the screw 3 held in a rotationally fixed manner.
  • Figure 2 shows that through the head 9 of the sleeve 8, a belt piece 11 and a fastening strip of a support basket 12 of the interior 13 of the helmet is clamped to the calotte 1.
  • a chin strap 14 is attached to the strap piece 11.
  • the carrier basket 12 consists in a known manner of a circumferential headband 16 provided with cushions 15 and basket straps 17 extending in a spider shape to the apex, which are provided with plastically deformable knobs 18 pointing towards the calotte 1 and rest against the calotte 1.
  • FIG. 2 shows that the head 2 of the screw 3 rests on the outside of the calotte 1 with a low overall height and is solid without a weakening point.
  • a bullet resistance can be achieved which is regularly above the bullet resistance for the calotte 1.
