Definitions

  • the invention relates to a protective helmet, in particular a full-face helmet for motorcyclists, with a pivotable visor, which is arranged on a visor frame and has a transparent visor and covers a viewing opening, ventilation openings being provided in the region of the viewing opening.
  • Full-face helmets are helmets that have an integrated chin guard.
  • Such a protective helmet is known from DE-PS 31 48 725, which has ventilation openings directly on the chin guard, to which an air collection chamber and ventilation pipes connect, the incoming air flow being directed through the ventilation pipes to the top of the viewing opening and from there against the visor screen .
  • this arrangement is less suitable for ventilation of the helmet interior, because of the required ventilation pipes a relatively high flow resistance is caused and accordingly the air flow rate is too low at lower driving speeds.
  • due to the dynamic pressure distribution on the underside of the helmet in this known construction it is not ensured that a sufficient amount of fresh air is achieved regardless of the respective angle setting of the helmet.
  • the object of the invention is to create an inexpensive helmet construction which optimally meets the competing requirements of a high level of comfort for the wearer and adequate ventilation, largely independently of the specific driving situation.
  • the ventilation openings are arranged in the sight in the region of the upper edge of the viewing opening. This arrangement of the openings ensures that the airstream passes through the ventilation openings and strikes the front of the helmet.
  • the air flow is directed against the visor disk in such a way that it sweeps along the visor at a relatively high throughput rate without causing turbulence in the interior of the helmet and exits at the bottom. Manufacturing efforts are therefore not required for the deflection of the air flow provided channels, but the deflection takes place through the top of the helmet itself. As a result, the flow paths can be kept short after entry so that the flow resistance is low.
  • the underside of the helmet is particularly well suited for ventilation due to the prevailing pressure conditions there.
  • the underside of the helmet is much less favorable for ventilation openings because indifferent, strongly angle-dependent flow conditions occur due to the stall occurring there.
  • the arrangement of the ventilation openings on the visor according to the invention is particularly advantageous because the visor can be kept and supplied as a separate spare part and can be produced independently of the actual helmet.
  • the ventilation openings are arranged in the approximately horizontal part of the visor frame.
  • the visor frame is manufactured using injection molding technology so that the ventilation openings can be made there without requiring an additional operation.
  • the ventilation openings are designed to be completely or partially closable by means of a slide. In this way it is possible to make the ventilation adjustable according to the requirements of the weather and the personal wishes of the wearer. In particular, an adaptation to the driving speed can also be carried out.
  • Such an arrangement is preferably implemented in such a way that several vertically extending ventilation openings are arranged in the sight frame, which can be brought into overlap with corresponding openings in a transversely displaceable slide in one end position of the slide, and which in the other end position of the slide by webs between the Openings of the slide are covered.
  • the vertical extension allows the ventilation openings to be completely covered by means of only a small slide path, to which the assignment of a covering web to each ventilation opening also contributes.
  • a reliable mounting and guiding of the slide can be realized particularly easily if only such small sliding paths are required.
  • the helmet shown in FIG. 1 comprises a helmet shell 1 with an integrated chin guard 2 and a viewing opening 3.
  • the viewing opening 3 is covered by a visor 4 which has a transparent visor disk 5 and a visor frame 6 carrying the visor disk 5.
  • the visor 4 is pivotally mounted in a manner known per se by means of a pivoting and latching arrangement 7 (not shown in detail).
  • the outer edge 8 of the helmet shell 1 is surrounded by an edge protector 9 made of elastic material.
  • the visor frame 6 comprises a fitting to the helmet shell in the closed state frame part 1 0, an adjoining frame part 11 and a further frame portion 12, at which the shield plate 5 is fixed.
  • the frame parts 1 0 , 11 and 12 are integrally formed from a casting.
  • the frame part 1o projects towards the helmet shell 1 in relation to the frame parts 11 and 12 and roughly follows their outer contour.
  • a sealing insert 13 is provided in the frame part 10 in order to achieve a sealing closure.
  • Ventilation openings 14 are made in the frame part 11.
  • the ventilation openings 14 are designed as vertically extending slots.
  • the visor plate 5 is provided with congruent openings 15, whereby a larger fastening area for the visor plate is achieved, since the visor plate 5 can extend up to beyond the lower edge of the ventilation openings 14.
  • a slide 17 engaging in a recess 16 of the frame part 11 is arranged from the outside.
  • the recess 16 leaves so much play laterally for the slide 17 that it can be displaced in the transverse direction so that in one end position in the slide provided ventilation openings 18, which correspond in shape to the ventilation openings 14, with these to cover, and that in the other end position of webs 19 of the slide 17, which lie between the ventilation openings 18 of the slide 17, come to lie above the ventilation openings 14 in the frame part 11 and close them.
  • the slide 17 can of course also take any intermediate positions, so that the ventilation openings 14 are then only partially open.
  • the airstream flows through the ventilation openings 14 against the helmet shell 1 and is deflected downward there, as indicated by the arrows 19, so that it is parallel behind the gap 9 between the edge protection 9 and the visor 5 behind it is directed down to this. Due to the suction effect in the area of the lower edge 21 of the chin guard 2 of the helmet, the used air is extracted at the bottom.
  • the arrangement of the ventilation openings 14 described above ensures that regardless of the angular position of the helmet and the locking setting of the visor 4, the driving air enters a helmet area where there is a high back pressure over a relatively large width, so that in connection with the brevity the air supply paths can achieve a high air throughput.
  • This high air throughput which exerts a suction effect on the air that is largely standing in the rest of the helmet area and thus dissipates used air, is not perceived by the helmet wearer as disturbing, since the air flow is directed past the sensitive eye area in particular.
  • the slider 17 can be fastened to the frame part 11 in that a knob is arranged on the slider 17, which can be slid into a transverse slot on the frame part 11.
