Definitions

  • the invention is directed to an integral protective helmet, in particular for motorcyclists, comprising a viewing opening and at least one ventilation opening arranged below it on the chin part.
  • Such an integral safety helmet is e.g. known from DE-PS 36 07 223.
  • the ventilation openings are arranged directly below the lower edge of the viewing opening, a fixed air guiding part being provided in the area of the ventilation openings in order to ensure that the air flow flowing down via the viewing window is independent of the respective inclination of the user head for the ventilation openings the helmet ventilation is used.
  • ventilation openings were also provided in the forehead area, ie above the view recesses, which can also be partially closed if necessary by means of a slide.
  • a fundamental problem in the implementation of such ventilation openings is that they have to ensure that adequate ventilation of the helmet interior is ensured when driving slowly, but that on the other hand the aerodynamics of the helmet are not significantly impaired by the ventilation openings during fast driving and do not interfere in the interior an unpleasant draft is created.
  • the helmets on the underside have to be closed even more than before, so that ventilation in particular is of considerable importance when driving slowly.
  • the invention is based on the object of designing a protective helmet of the type mentioned at the outset in such a way that adequate helmet ventilation which is perceived by the user as being pleasant can be implemented at any driving position and speed.
  • this object is achieved in that an air guiding arrangement is arranged on the lower edge of the chin part so that it can be moved out and forms a ventilation slot.
  • This construction is based on the knowledge that the flow conditions in the area of the lower edge of the chin part are particularly favorable for the introduction of a ventilation opening in this area, because there is a particularly strong flow around the helmet with the formation of eddies, so that a sufficient amount even when driving slowly can be introduced by air without this being significantly dependent on the user's head posture.
  • the inflow of air is not restricted to a few specific areas, but takes place practically along the entire underside of the chin part, so that a very uniform air flow is formed inside the helmet.
  • the air guiding arrangement can be arranged so that it can be pushed out.
  • a pivotably mounted air guide arrangement is arranged on the lower edge of the chin part.
  • the air guide arrangement advantageously has a deflection attachment for the incoming air flow, which extends approximately parallel to the plane of the viewing opening. This ensures that the incoming air flow in parallel towards the viewing opening, i.e. is deflected towards the inside of the visor covering this, on the one hand preventing fogging of the visor, but above all preventing the air flow from directly hitting the face of the user.
  • the deflection attachment can have a guide attachment which has air passage openings and extends in the direction of the inner wall of the chin part. Through these air passage openings, which e.g. can be formed as bores, fine metering and distribution of the air flow inside the helmet can still be achieved.
  • the air guiding arrangement is particularly advantageously arranged in a recess in the chin part in such a way that its lower edge is flush with the lower edge of the helmet in the closed state.
  • This can expediently be realized in such a way that the air-guiding arrangement has pivot bearing lugs which are angled upwards and pivot bearings are formed at the free ends thereof.
  • a pivoting movement can be realized, which approximately represents a purely translational movement in the region of the transition between the air guiding arrangement and the lower edge of the helmet, so that in the closed state this transition region has almost no edges that project outwards. This will result in high speeds good aerodynamics are achieved and wind noise is avoided.
  • An integral protective helmet for motorcyclists shown in the drawing comprises a helmet cap 1 which is designed as such in a conventional manner and has an integrally molded chin part 2 and a viewing opening 3 which is covered by a visor 5 which is pivotably mounted on a pivot bearing 4.
  • the inside of the helmet cap 1 is provided with a lining 6.
  • a locking device 7 is provided for a chin strap, not shown in the drawing.
  • An air guide arrangement 8 is arranged in the region of the lower edge 9 of the chin part 2 in a corresponding recess 10 of the helmet cap 1.
  • the air guide assembly is pivotally mounted about pivot bearing 11 such that the rear side edges 12 of the air guide assembly 8 are flush with the corresponding edges 13 of the recess 10 when the air guide assembly is pivoted.
  • the configuration of the air guiding arrangement 8 can be seen particularly well from the broken-open area on the front of the chin part 2.
  • the air guiding arrangement 8 comprises a projecting lip part 14, to which a deflection projection 15 adjoins to form an approximately L-shaped, rounded and thus aerodynamically advantageous cross section.
  • the deflection extension extends approximately parallel or at an acute angle to the plane of the viewing opening 3 or the sighting disc 16.
  • a guide extension 18 which extends to the inside 17 of the chin part 2 and which has a plurality of through bores 19 .
  • a ventilation slot 21 is formed between the lower edge 20 of the chin part and the lip part 14 of the air guide arrangement 8, which extends transversely around the chin part and whose width can be arbitrarily changed in accordance with the pivoting state of the air guide arrangement 8.
  • an air flow 22 occurs, which is guided on the deflection projection 15 in the direction parallel to the inside 17 of the chin part 2 or approximately parallel to the inside of the visor disk 16, passing through the through bores 19 in the guide projection 18 and still according to a desired distribution is evenly distributed over the inside of the helmet.
  • guide projection 18 can also be dispensed with if the greatest possible air throughput appears desirable.
  • a latching mechanism can be provided for the pivoting movement of the air guide arrangement 8 in order to make latching possible in the closed state or also in defined intermediate positions.
  • Such locking arrangements are known in principle for the pivoting movement of the visor in different embodiments.
