  • the present invention relates to a crash helmet for motor-cyclists and in particular to a crash helmet having an automatic system for opening and closing the visor, and including many other advantages, as for example a much more efficient ventilation i.e. air circulation system, with a very limited noise inside the crash helmet when all ventilation holes and slits have been closed, and a system for engaging the visor, which is extremely easy to use, and lastly, an improved internal stuffing means.
  • a much more efficient ventilation i.e. air circulation system with a very limited noise inside the crash helmet when all ventilation holes and slits have been closed
  • a system for engaging the visor which is extremely easy to use, and lastly, an improved internal stuffing means.
  • the difficulty in assembling and removing the visor of crash helmets is known. This operation is very often carried out using one or more screws or engaging systems, which are particularly complicated. Since the replacement of the visor is an operation which is very often done by the motor cyclist, for example in order to replace the visor with a darker one in the summer, or with one which does not get tarnished, during the winter, the present invention intends to overcome the aforesaid drawback, by providing an engaging system which has a simple construction and which is easy to use. Another object of the present invention is that of allowing an automatic opening and closing of the visor, by particularly simple means. In fact, it is known that the crash helmet during warm seasons is particularly uncomfortable due to the heat which is present inside the crash helmet. This drawback is particularly noticed when the crash helmet is used in town, at low speeds, with repeated stops for example in front of traffic- lights. In order to overcome this disadvantage, the motor cyclist must continuously open and close the visor, in order to let air enter inside the crash helmet for cooling.
  • Another feature of said automatic system is that it can be rendered inoperative so that the usual manual control can be used instead.
  • Another object of the present invention is that of providing means which allow to cool or ventilate the interior of the crash helmet in order to increase comfort, expecially during the warm season, without need to lift the visor, said means allowing to obtain an PCMT94/00044
  • One object of the present invention is the realization of a system which limits at the most the number of holes on the external surface of the crash helmet, maintaining however the same ventilation efficiency with respect to conventional systems, or even improving it. Due to the reduced number of holes, the noise inside the crash helmet (measured in decibel) when the apertures of the present invention are closed, is much lower than that of conventional crash helmets.
  • Another object of the present invention is to render more handy the automatic movement of the visor and improve its air and water tightness. This is obtained by completing the automatic system with a noticeable innovation with regard to the seal.
  • rubber or glued closed cell polyurethane foam has been used. The disadvantage of such solution is that rubber causes friction with respect to the visor, whereas the closed cell polyurethane foam glued on the shell cannot be replaced in order to adapt it to another type of visor.
  • the present invention has the object to provide means which allow the air to freely circulate inside the crush helmet when the visor is open, or in combination with the ventilation systems, in order to improve comfort and avoid perspiration, expecially during the warm seasons.
  • These means will also allow to perform a periodic cleaning of the interior of the crash helmet, and will ensure an optimum adherence of the crash helmet's internal stuffing, which is also replaceable so as to conform to the geometrical configuration of every single head.
  • the present invention has also many other advantages which will become apparent from the following description.

  • Figs. 12a-12f show a lateral ventilation system of the crash helmet of the present invention
  • Figs. 13a, b, c show a special kind of internal stuffing of the crash helmet of the invention.
  • the cylindrical cover 1 has an upper surface or wall 2, a lateral wall 3 provided with a slit 4, and a cylindrical part of pin 5 which is integral with the inner side of the upper surface 2 and coaxial with the lateral wall 3.
  • This pin 5 is not visible in Fig. 2, because it is hidden inside the cover 1.
  • the cover 1 On the upper part, the cover 1 has a guide seat 6, for two sliders 7, 8, the first of them being connected to an element 7a having lower saw teeth 7b arranged along a circular sector.
  • Fig. la shows the analogous arrangement to Fig. lb, but reversed.
  • the second slider 8 is rigidly connected, as shown in Fig. Id, to a lower element 8b provided with a lateral projection 8b which is substantially flat.
  • the visor 9 is engaged on the cover 1 in the following manner: the lateral slit 4 receives the projection 10, this being made possible by the fact that the material which forms the visor 9 can be deformed.
  • the slider 8 is displaced to the left until it passes through a slit on the lateral wall of the cover 1, by means of the flat portion 8b which completely enters into the slit 12 on the lateral cylindrical wall 11' of the visor.
  • the slider 8 will then be located in the position "closed” in fig. 2. Therefore the visor 9 is engaged on the crash helmet quickly and easily.
  • this just described embodiment may be modified in different ways; for example, two sliders could be provided, corresponding to the slider 8, in order to engage the visor 9 on the cover 1 , the flat portions of said sliders, corresponding to 8b, would be introduced in two slits (for example diametrically opposite ones) provided on the cover 1 (corresponding to the slit 12) , whereas a third slider (corresponding to the slider 7) would serve for the conversion of the control of the visor's movement from "automatic" to "manual” or vicever ⁇ a.
  • the pin 5 inside the cover 1 is introduced into the cylindrical hole 19 of a hollow cylindrical portion 18 integral with the base element 14, being fixed preferably by means of a snap ring 13 to said base element 14, which by means of screws 15, 15' is in its turn fixed to the crash helmet, these screws 15, 15' passing through slots 16, 16' which during assembling allow an adjustment of the position of the visor 9 with respect to the crash helmet.
  • a helicoidal spring 17 is fixed at its ends 17a and 17b to the cover 1 and to the base element 14 respectively, and its arrangement is coaxial with the hollow cylinder 18.
  • the base element 14 has an elastic tongue or sector 20 provided with one or more teeth which engage, when the slider 7 is pushed to the left in Fig. 2, respective saw teeth 7b of the lower element 7a; that is when the slider 7 is in the position "manual".
  • the sector 20 does no more engage the saw teeth 7b.
  • Figs. 1 and 2 may be present both on the right side as on the left side of the crash helmet.
  • the spring 17 pushes the visor in the position shown in Fig. 6a, when external forces are absent, or if these are small, when the user is driving for example at a reduced speed and the pressure of the air, as indicated by the arrow A, is not strong enough to lower the visor.
  • the pressure of the air becomes important (arrow B of Fig. 6b) and the visor 9 will progressively rotate downwards while the spring 17 is progressively twisted, until the visor 9 is completely closed.
  • the opening and the closing of the visor will occur in a more or less pronounced manner, depending on the velocity of the motor cyclist. He will not have its sight disturbed at high speeds, whereas in front of traffic-lights and during stops the visor 9 will automatically open.
  • the arrows M, A, C, 0 indicate respectively the tran ⁇ lational directions of the sliders 7 and 8, towards the positions “manual”, “automatic", “closed”, “open”, respectively.
  • the number 21 indicates a plurality of holes which allow to fix the lower end 17b of the spring in different positions, adjusting in this way the exact velocity which allows the visor to rotate downwards , according to the wish of the user.
  • FIG. 7a shows a system in which the pulling force or traction of a helicoidal spring 22 is used instead of its twisting.
  • the spring 22 is connected to the crash helmet by a pin or screw 23, at one of its ends, whereas at its other end it is connected to a hook 25 having a threaded end 26 inserted in a micrometer screw 24 which allows to adjust in a precise way the initial tension of the spring 22.
  • the micrometer screw 24 is integral with the cover 27 which corresponds to the cover 1 of the preceding embodiment. Both in the preceding embodiment, as in this embodiment, the covers 27 and 1 may be connected to the respective base element, by the interposition of bearings 28. These bearings will promote an even more free sliding of the visor. It follows, moreover, that the present invention has the advantage that projections or recesses with respect to the visor are absent, that is all embodiments have parts which are flush with the visor.
  • the visor 9 is connected to two lifting arms 29, 29' which are hinged on a support 30 which is for example fixed by means of screws 31, 31' to the rear part of the crash helmet.
  • a helicoidal spring 32 On an intermediate axis between the two lifting arms 29, 29', there is arranged a helicoidal spring 32, whose one end 34 is fixed to the ⁇ uppot 30, the latter being stationary and fixed on the crash helmet, whereas the other end of the spring 32 is integral with the intermediate axis.
  • a cover 37 which is fixed by means of screws 37a on the crash helmet, at the points 38, covers the lifting arms 29, 29' and the support 30.
  • a slider which slides along a corresponding slit, said slider being integral with a tongue or leaf spring 36, which when the slider 35 is shifted in the direction of the arrow E, will engage the saw teeth of the cylindrical element 33, whereas in the opposite direction, the leaf spring 36 will disengage itself from the cylindrical element 33.
  • the cover 37 has obviously a protective function, and it serves also to optimize the streamline of the crash helmet.
  • the manual control is characterized in that the leaf spring engages a groove between two saw teeth, thus blocking the visor in a predetermined generic position, and by displacing the visor with his hand upwards or downwards, the user will hear a series of clicks when the leaf spring passes over successive grooves. The action of the spring, which renders automatic the movement of the visor, will therefore be cancelled.
  • This latter embodiment has the further advantage that the visor, by rotating on a larger radius, will position itself at the point of maximum aperture, in a location almost parallel to the shell, thus avoiding aerodynamic problem ⁇ by which the crash helmet tends to overturn, and increasing the comfort when the user is driving with the visor in the lifted position. Also in this case, the system has not only its control parts concentrated in a unique position, but it is conceived in order to be completely flush with the visor, avoiding projections which could influence the streamline properties and the safety properties of the crash helmet.
  • Figs. 10a, 10b and 10c show the crash helmet of the present invention, provided with a seal 40 along the edge of the front aperture of the crash helmet.
  • the seal 40 is made of two separable parts, the first part being directly fixed to the shell 41 so a ⁇ to be stationary, and being formed by a seal 42 of moulded plastic material, while the second part is engaged by means of its projection 44 inside the groove 45 having a complementary form. Since the seal of closed cell polyurethane foam will have a rectilinear development shorter than that of the rigid seal, once it is engaged in the groove 45 it will not spontaneously get out of the groove.
  • the second seal 43 is made by clo ⁇ ed cell polyurethane foam, commonly called mou ⁇ e or aer ⁇ top.
  • the ⁇ eal 42 is formed by a ridig or almost rigid material, whereas the ⁇ eal 43 has the opposite property, that i ⁇ it confor ⁇ perfectly to the inner contour of the visor thus ensuring a perfect tightness with respect to air and water, without however causing friction which would damage the ⁇ eal itself and would render more difficult the movement of the vi ⁇ or 9. Therefore, the ⁇ eal 40 which forms part of the present invention, facilitates the automatic movement of the vi ⁇ or and improves tightness with respect to water and air.
  • Figs. 11a and lib show a double slider 50, which i ⁇ arranged as indicated in Fig. lie, centrally and on the front part of the cra ⁇ h helmet, immediately below the vi ⁇ or 9.

Abstract

Casque comportant un système automatique d'ouverture et de fermeture de la visière mettant à profit la pression exercée par l'air. Un ressort de rappel maintient la visière (9) dans sa position d'ouverture maximale lorsqu'il ne subit aucun effort extérieur. Lorsque la vitesse augmente, la pression exercée par l'air anime la visière d'un mouvement progressif de rotation vers le bas. Ce casque comporte également un système de ventilation (50, 60) utilisant un minimum de fentes ou de trous ménagé(e)s dans l'enveloppe du casque, ce qui réduit sensiblement le bruit à l'intérieur du casque lorsque le système de ventilation n'est pas utilisé. Enfin, ledit casque comporte un ensemble de rembourrage interne (67) qui est très pratique sur le plan du nettoyage et de l'adaptabilité à la forme particulière de la tête, et qui est également caractérisé en ce qu'il ménage à l'intérieur du casque des espaces dans lesquels l'air peut circuler librement.
