Definitions

  • the invention relates to a protective helmet of the type mentioned in the preamble of claim 1 and resulting from DE-OS 31 37 680.
  • the air guiding device is designed as a V-shaped channel located below the ventilation openings. This has its greatest depth in the longitudinal central area of the chin guard, which decreases steadily from there to the rear. Due to this design of the air guiding device, when the motorcyclist is in an approximately normal head posture - which is shown in FIG. 5 - only the air flow which flows approximately horizontally into the protective helmet due to dynamic pressure reaches the helmet interior via the ventilation openings. However, the amount of air flowing into the latter in most cases is not sufficient for good helmet ventilation.
  • the object of the invention is therefore to provide a protective helmet of the type mentioned in the preamble of claim 1 such that, in addition to the air flow acting approximately horizontally on the protective helmet, the air flow flowing downward through the viewing window is effective for helmet internal ventilation, regardless of the respective inclination of the motorcycle driver's head is exploited.
  • the air guiding part is designed according to the invention in such a way that it protrudes beyond the adjacent contour of the chin guard with an inflow surface that is directed approximately against the inflow direction, the air flow flowing downward through the viewing window is dammed up in the area of the ventilation openings and introduced into the helmet interior via the latter.
  • This is particularly advantageous in the case of a motorcycle with a windshield - which can be located on a motorcycle fairing - since the air flow flowing over the windshield of the protective helmet is divided at the upper edge region of the viewing opening and partly downwards via the helmet tip and partly via the viewing window and thus gets into the helmet interior in the manner mentioned.
  • the height of the air guiding part corresponds approximately to the wall thickness of the chin guard and is thus approximately 5 mm (feature of claim 2).
  • the air guiding part is designed like a frame with a rectangular outline, the narrow side lying below having the greatest height and thus blocking the air flow flowing downward through the viewing window.
  • a protective helmet is usually provided with a plurality of ventilation openings lying next to one another, a plurality of frame-like air guiding parts are also arranged next to one another, each of which surround ventilation openings lying one above the other (features of patent claims 4 and 5). This will make the helmet flow air is optimally introduced into its interior, for which the design of the inner walls of the narrow sides of the air guiding parts, as set out in claim 5, is also advantageous. If a protective helmet has only one ventilation opening or a plurality of ventilation openings lying one above the other, these are of course only surrounded by a single frame-like air guiding part.
  • the air guiding part according to the invention can advantageously also be retrofitted in a simple manner.
  • an insert part consisting of one or more frame-like air guiding parts lying next to one another is expediently made of plastic, which is glued onto the chin guard.
  • the motorcycle driver's protective helmet 1 shown in FIGS. 1 to 3 has a viewing opening 2, which can be covered by a viewing window 3. This is pivoted up and down together with a chin guard 4 on two opposite bearing bolts 5 stored on protective helmet 1. As can be seen in FIGS. 3 and 4, the chin guard 4 has a truncated cone-shaped section 4 ⁇ . This is provided below the edge of the viewing opening 2 and in the longitudinal central region of the chin guard 7; six rows of ventilation openings 7 are arranged side by side. The ventilation openings 7 can run parallel or obliquely to the edge of the viewing opening 2.
  • the motorcycle shown in FIG. 1 has a motorcycle fairing 8 on which a windshield 9 is located on the front.
  • the air stream a which acts on the windshield 9 when the motorcycle is being driven is guided up to approximately the upper edge region of the viewing opening 2 and is divided there into an air stream b flowing over the helmet tip and into an air stream c flowing downward via the viewing window 3. Even if the motorcycle does not have a windshield 9, the protective helmet 1 is acted upon by the air flow approximately as described.
  • the air flow c flowing down over the region of the viewing pane 3 is introduced via the narrow side 11 below of a frame-like air guiding part 10 while passing the ventilation openings 7 into the helmet interior 1 ⁇ (FIGS. 2 and 4).
  • the frame-like air guiding part 10 is rectangular in shape and consists of an underlying and an overhead narrow side 11 or 12, the underlying narrow side 11 having a height h of about 5 mm - which corresponds approximately to the wall thickness of the chin guard 4 -, while the height h ⁇ of the overhead Narrow side 12 is about 2-3 mm.
  • the two narrow sides 11 and 12 are each connected to one another by external webs 13, each of which tapers upwards in a wedge shape. Since the narrow side 11 of the air guiding part 10 lying at the bottom has a height h of approximately 5 mm, it protrudes in a nose-like manner beyond the adjacent contour of the chin guard 4, thereby ensuring good air introduction into the helmet interior 1 ⁇ .
  • FIG. 3 shows, in the protective helmet 1 according to the invention on the frustoconical section 4 ⁇ of its chin guard 4, six rows of ventilation opening 7 are arranged side by side in the central region of its longitudinal extent; there are three ventilation openings 7 one above the other. Since these are each surrounded by an air guiding part 10, six of these lie side by side, with a web 13 of the air guiding part 10 each lying between two adjacent rows of ventilation openings 7. If a protective helmet 1 only has ventilation openings 7 lying one above the other, these are of course only surrounded by an air guiding part 10.
  • Fig. 4 it can be seen that the mutually facing, in each case one of the ventilation openings 7 adjacent inner walls of the underlying and overhead narrow sides 11 and 12 in a vertical section each as obliquely from the top outside inward to the ventilation openings 7 rounded fillets 11 ⁇ and 12 ⁇ are trained.
  • This measure ensures that when the motorcycle is being driven, the air flow c flowing downward through the lens 3 is introduced in an aerodynamically optimal manner and specifically through the air guide parts 10 and via the ventilation openings 7 into the helmet interior 1 ⁇ .
  • the air guide parts 10 are expediently formed in one piece on the protective helmet 1 by appropriate design of the injection mold. However, it is also conceivable to prefabricate one or more adjacent air guide parts 10 as a one-piece loose insert part made of plastic or the like and to glue them to an existing protective helmet 1 in the area of ventilation openings 7.
