Definitions

  • the invention relates to a protective helmet, in particular for motorcyclists, with a front shell part, which has a viewing opening and a chin guard, and a rear shell part which can be folded upwards about a swivel joint arranged on the top of the helmet and secured in the folded position by a closure which can be released from the outside are.
  • Helmets of this type are, on the one hand, of the so-called jet helmets, which can be easily removed from the head, but do not protect the chin and lower jaw, and, on the other hand, the usual ones which consist of a one-piece helmet shell Differentiate between full-face helmets that have a chin section that protects the chin and lower jaw (so-called chin guard), but cannot be removed from the head without exerting force and therefore can cause severe spinal cord injuries when motorcyclists have been injured from the head.
  • Protective helmets of the type mentioned at the outset have the advantage that they protect the chin and lower jaw and nevertheless - due to the fact that the two shell parts can be folded apart - without an application of force from the head after an accident can also be removed by a helper because of the removable closure.
  • a disadvantage of the known helmets is that the protective lens, the so-called visor, previously used to protect the eyes, so-called visor, becomes dirty over time, mists up in cool weather, splashes when it rains and covers it with snow in winter so that the view can be extremely impaired.
  • the frequently necessary wiping of the protective pane leads to the pane being scratched after a short time.
  • motorcyclist hoods including those which are provided with a helmet shell protecting the skullcap (FR-A 1 089 472), with a ram-air nozzle in order to gain access to the driving wind as well as rain and To prevent snow to face.
  • Helmets the helmet shell of which protects the entire head, including the face and the back of the head, have so far not been equipped with ram air nozzles, despite the need that has always existed, apparently because it did not seem possible to achieve sufficient congestion.
  • the invention is based on the requirement to create a helmet of the type mentioned at the outset, which always ensures a perfect view, especially in rain and snow.
  • the helmet according to the invention not only reliably protects the face against rain, snow, insects, dust, etc., but also that there is a buoyancy effect.
  • the buoyancy acting on the helmet in the driving wind can be increased further by suitable shaping of the ram air nozzle and the chin protection part, so that the helmet is carried by the buoyancy even at low speeds and a buoyancy arises at higher speeds that allows the driver to put his head on to support the cushion running under the lower jaw. This avoids the annoying tension in the neck muscles that occurs during long trips with the previous helmets.
  • the buoyancy effect allows the production of heavier and thus better protective helmets.
  • the arrangement of the swivel joint of the two shell parts on the forehead region of the helmet on the one hand ensures that when the front helmet shell part is opened, the chin part of the lower jaw of the wearer does not swings upwards but slightly downwards, the pad lifts off the lower jaw and thus avoids the risk that the lower jaw of an injured motorcycle rider will be torn forward with the chin guard part when the front shell part is opened.
  • the stability of the helmet shell is not adversely affected by the swivel joint, since the swivel joint and thus also the butt joint between the two shell parts are not, as is the case, for example, in US Pat. No. 3,362,403 is arranged in the central helmet area, which is particularly critical for the stability of the helmet.
  • a firm fit of the helmet on the head is achieved without the need for a chin strap.
  • the chin protection part of the front helmet shell part preferably extends under the lower jaw of the helmet wearer, to the extent that this is possible without risk of injury to the neck of the helmet wearer. This ensures that the part of the cushion that runs under the lower jaw is reliably held tightly against the lower jaw by the chin protection part. In addition, this ensures that the helmet sits firmly on the head and prevents the helmet from being torn away from the head in the event of an accident, as was the case with previous helmets that were only held by a chin strap on the lower jaw.
  • the ram air space according to the invention is essential for the chin protection part which is guided close under the lower jaw, because without it, ie with a viewing opening covered by a viewing window, the viewing window would lack air circulation fogged up due to exhaled air.
  • the pad can be air-permeable to a limited extent or provided with air passage channels, the air permeability of course only being dimensioned as large as without Impairment of the congestion effect is possible.
  • the helmet shell shown in Fig. 1 consists of a front, face and jaw protecting part 1 and a rear part 2, which extends over the back of the head to the forehead and the jaw.
  • the two parts 1, 2 are pivotally connected to one another by a swivel joint 3 arranged in the region of the forehead.
  • Part 1 has a viewing opening 4 in the area of the eyes and nose.
  • the edge 5, which surrounds this opening 4, is bent outwards and a sealing strip 6 is fastened on it.
  • a pipe socket 7 made of acrylic glass is attached to the sealing strip 6.
  • the edge 8 is expanded by the edge 5 when a blow occurs done from the front on the pipe socket 7. If this leads to the breakage of the glass, it is blown open at the edge 8 (e.g. along a predetermined breaking line), so that the fragments are deflected by the edge 5 and fly away from the opening 4. This avoids any risk to the eyes in the event of an accident due to splinters in the pipe socket 7. Because the pipe socket 7 is only plugged onto the sealing strip 6, that is to say is exchangeably attached to part 1, the driver can, depending on the weather conditions, e.g. Use a colorless acrylic glass when it rains, a colored acrylic glass to protect against glare at sun and at night.
  • the axis of rotation of the joint 3 runs perpendicular to the longitudinal direction 9 of the pipe socket 7.
  • the edges 11, 12 of the two parts 1, 2 which abut one another in the folded position shown in the drawing are stepped in cross section and engage one above the other in such a way that the outer and Inner surfaces of the two Connect shell parts 1, 2 flush to each other.
  • the two shell parts 1, 2 are secured in the folded position by a snap lock 13, the locking of which is automatically engaged when the two shell parts are folded and can be released again by pressing a pushbutton 14.
  • a sealing ring 15 made of closed-cell foam is tightly attached, which runs around the face and the lower jaw of the helmet wearer and is dimensioned so thick that it lies close to the face or lower jaw over its entire circumference.
  • the sealing ring 15 ensures that the air flowing in during the journey through the pipe socket 7 (driving wind) is stowed in the pipe socket and the space communicating with it between the helmet shell part 1, the face of the helmet wearer and the sealing ring 15 and thus not through the rear Part of the helmet and the ventilation and sound passage openings provided therein (not shown) and between the inner lining 17 of the helmet and the neck of the helmet wearer can escape into the open.
  • driving an air cushion is created in the pipe socket 7 and the communicating space in front of the face of the helmet wearer, and this cushion of compressed air prevents the ingress of dust, raindrops, insects, which could otherwise get into the eyes and would at least impair vision.
  • the helmet is put on with parts 1, 2 unfolded and first you put part 2 on the back of your head, then you fold the front part 1 down and presses both parts together until the closure 13 snaps into place.
  • the push button 14 is pressed and the front part 1 is folded up in the direction of the arrow 18, whereupon the rear part 2 can be removed without any effort. This ensures an extremely careful removal of the helmet from the head of the helmet wearer, which can be life-saving for motorcyclists who have had an accident.
  • the rear helmet shell part 21 of the helmet shown in FIGS. 2 to 7 is designed in the manner of a conventional jet helmet and can be used as such, for example by motorcyclists, and later added by attaching the front helmet shell part 22 to the integral helmet according to the invention.
  • the front shell part 22 is fastened with its upper edge part 24 delimiting the viewing opening 23 to one leg of a hinge 25, the other leg of which is fastened to the front edge of the rear helmet shell part 21 by means of a cross-sectionally U-shaped fastening piece 26.
  • a bolt 28 is fastened, which is latched into a hole in a ram air socket 29 seated on the sealing strip 27 and back it up.
  • the ram air nozzle 29 is made of transparent material, for example polycarbonate, and is tapered towards the front in order to achieve a good congestion effect.
  • the ram air nozzle can be released from the front shell part 22 by compressing it vertically, so that its two side regions are spread apart and disengage from the bolts 28.
  • the Ram air socket 29 can have predetermined breaking lines running through the two holes for the bolts 28, so that potentially dangerous splintering of the socket in an accident is avoided.
  • the chin protection part 30 of the front shell part 22 extends to below the lower jaw of the helmet wearer, and it and the ram air nozzle 29 are shaped in such a way that buoyancy acts on the helmet in the driving wind.
  • a sealing pad 31 made of closed-cell foam is attached to the inside of the front shell part 22, which, when the helmet is on, runs under the lower jaw to the two cheekbones (cheekbones) of the helmet wearer, one in the area of the cheekbones of the helmet wearer between the pad 31 and the shell part 22 arranged insert 32 made of firmer material ensures that the pad 31 is pressed tightly against the cheeks of the helmet wearer.
  • the ends of the pad 31 lie close to a sealing pad 33 arranged on the inside of the edge of the rear shell part 21 which delimits the viewing opening 23 and which, when the helmet is put on, lies tightly on the forehead of the helmet wearer, so that the two pads 31, 33 are together form a ring-shaped sealing pad around the face and under the lower jaw.
  • the lower part of the sealing pad 31 is fastened to the chin protection part 30 projecting below the lower jaw, and a downwardly projecting apron 34, for example made of stamoid synthetic leather, is attached to it and protects the neck from drafts.
  • the sealing pads 31, 33 completely seal off the ram air space against the space between the rear part of the helmet and the head of the helmet wearer and effect it In addition, the helmet sits firmly on the head, so that the helmet does not "flutter" in the driving wind, even at high speeds, like previous helmets.
  • the sealing pads 31, 33 or the sealing ring 15 could, however, also be permeable to air to a limited extent, the permeability to air being dimensioned in such a way that on the one hand the congestion effect is not impaired, ie a dynamic pressure sufficient to protect the eyes from rain, snow, insects etc.
  • the fastener securing the two shell parts 21, 22 in the folded position has two locking devices arranged on the two cheek sides of the helmet, each formed by a resilient pawl 36, which can be disengaged by means of two cords 38 connected to one another under the lower jaw and to a handle badge 37 (Fig. 4).
  • the handle badge 37 is provided with an inscription made of fluorescent paint (“pull”), which shows each helper in an accident how to open the helmet.
  • the closure 36-38 has opposite the closure 13 the advantage that no larger holes that impair the stability of the helmet shell have to be drilled into the helmet shell, and that the helmet can be opened by pulling on a single handle that is easily accessible in any position of the accidented motorcycle driver.
  • FIG. 4 The butt joint at which the two shell parts 21, 22 abut one another is shown in FIG. 4 in the area of the pawl 36 and in FIG. 5 in the remaining area.
  • the edge 40 of the rear shell part 21 engages in a form-fitting manner in the fork-shaped widened edge 41 of the front shell part 22, which ensures a high rigidity of the helmet.
  • the resilient pawl 36 is fastened to the front shell part 22 and engages in a recess in the rear shell part edge 40, the inner fork part of the front shell part edge 41 being removed there.
  • a chin strap was attached to the helmet shell in the area of the ears.
  • a U-shaped earpiece 43 On the ear areas of the rear helmet shell 21, which are now free due to the chin strap falling away, a U-shaped earpiece 43, with the open side pointing downward, is arranged, as shown in FIG. 7, which absorbs the sound entering the helmet from below Ear conducts.
  • a protective pane can be placed in the area of the viewing opening or immediately in front of the wearer's eyes be ordered.
  • the protective screen must be arranged as far as possible from the front opening of the ram air nozzle and, for example, only attached to the ram air nozzle or to the front shell part by means of thin webs so that the air can circulate around the disc and the ram air effect is not impaired.
  • the helmet is especially designed for motorcyclists; but it can also e.g. used by ski racers, who also depend on good visibility and safe removal of the helmet after a fall.
