Definitions

  • the present invention relates to a motorcycle protective helmet equipped with a retention device making it possible to improve its positioning and its retention on its user.
  • the usual device for securing helmets consists of a simple chin strap made up of two textile ribbons, or leather straps, each secured by one of their ends to the base of the helmet shell at two lateral and opposite points thereof. Their free ends are connected together, under the chin of the user, by a loop or other suitable member.
  • this uncomfortable device is all the more so since it is tight enough to ensure effective support.
  • the anchor points of the chin strap to the shell of the helmet being clearly offset relative to the transverse median plane of the skull of the user, the helmet will tend, during an impact, to tilt from back to front in a rotational movement around an axis passing roughly through the ears of the helmet wearer.
  • Such a device cannot therefore prevent the helmet from leaving the head during a simple shock or followed by twists and turns. Furthermore, in the case where the helmet is subjected to a tearing force directed from the base towards its top, this force is fully transmitted to the lower part of the user's chin, in the form of a pressure which can be dangerous. because of the small surface of the chin strap by which it is applied.
  • This device as uncomfortable as it is dangerous, has already been improved by the adoption of a device for securing helmets essentially consisting of a rigid skirt extending the base of the helmet shell and formed of two articulated parts, one at the front, the other at the rear of the hull, locked by their movable ends in the lateral zones of this same hull.
  • this device is not without drawbacks.
  • the members enabling the locking device to be actuated are easily accessible from outside the helmet and can come into contact with an asperity of the ground during an impact, hence unlocking and therefore possible opening of at least one part of each half-skirt.
  • the introduction and removal of the helmet - mainly if the user is warmly dressed in a sweater or high collar jacket, which is common for a motorcyclist - is difficult because of the range of movement described by the ends of each half-skirt when they are opened or closed.
  • the retention is therefore effectively ensured - mainly at the front of the helmet - only by the padding of flexible foam pressing its upper face against the lower face of the user's chin.
  • the slightest shock subjecting the helmet to a torque is enough to deform this padding so that the user can see his helmet, if not detach from his head, at least rock back and forth until the retention system come and lean against the underside of his nose. From where a situation at the very least uncomfortable and dangerous, mainly if the interested person wears a pair of glasses, the upper part of it then coming to crash against his browbones ...
  • helmets of this type cannot benefit from the anti-theft systems adopted today by all manufacturers of modern motorcycles and consisting simply of an anti-theft hook secured to the machine and provided so that the buckle can be hung there. metal fitted to the chin strap of all ordinary protective helmets.
  • This system is not a foolproof efficiency, since it is easy, for a possible thief, to cut said chin strap in order to appropriate the helmet.
  • this device makes it possible to reduce to a certain extent the risk of theft and above all has the advantage of having been adopted unanimously by all manufacturers of motorcycles without this imposing on helmet manufacturers having to modify their productions.
  • any owner of a helmet fitted with a securing device without chin strap - therefore without attachment loop - cannot use the anti-theft hook with which his motorcycle is nevertheless fitted, and must purchase a additional anti-theft accessory, expensive, heavy and bulky, generally consisting of a large chain or metal loop passing on the one hand around the chin part of the helmet to be protected and on the other hand around a fixed part of the motorcycle.
  • the helmet, object of the invention has an improved securing device which, according to the variant envisaged, makes it possible to avoid all or part of the faults inherent in the prior techniques and ensures that it can fully fulfill its protective role of the cranial box. , whatever the stresses it may undergo during a single shock or followed by twists and turns, especially during a fall.
  • this device is characterized in that it essentially consists of a substantially toroidal bead, concentric with the opening delimited by the lower edge of the helmet shell, this when the helmet is closed.
  • This bead is linked to the base of this shell by means of one or more flexible elements.
  • the bead consists of one or more sections which come together end to end when the helmet is closed and thus form a kind of collar around the user's neck. The base of the face and the skull of the latter then being in abutment against the upper face of this necklace.
  • the helmet being locked in the closed position, the perimeter of the bead is invariable.
  • Each of the parts making up the whole bead may be rigid or made of a flexible material - at least in the plane parallel to that of the base of the shell - but not extensible, or flexible and elastic but armed with a flexible core - at least in the plane parallel to that of the base of the helmet - but not extendable.
  • the bead is covered with a certain thickness of padding - an element of comfort and security - at least in the areas of its external surface liable to come into contact with the user.
  • the bead is formed of two or more sections, each of them can be articulated (in particular if the bead is rigid) by one of its ends at the end of the neighboring section, one end of at least one section being separable (unlocking) of the end of the section against which it bears during locking (this in order to allow the opening of the collar that constitutes the closed bead).
  • the bead is made up of two or more sections, the two ends of each section can also be kept in contact, helmet closed and locked, against the neighboring section or sections, and completely dissociate from it (no articulations) to allow opening the helmet.
  • the bead is in one piece and split at a single point (flexible bead)
  • the two ends determined by this break come to bear one against the other and are held there by a locking system (closure of the collar) and - after being unlocked - can be moved away from each other (opening of the collar) thanks to the elastic deformation which is imposed on the bead in order to be able to remove the helmet.
  • the ends of two neighboring sections can also come to bear - or be articulated - on either side of an intermediate rigid part secured either to an extension of the hull, or to a rigid articulated part at the base of the hull, either of a set of several rigid parts hinged together, at least one being articulated at the base of the hull, or of a flexible element linked by its upper end to the base of the hull.

  • each flexible frame integral with an extension, rigid, articulated or flexible, of the base of the shell and sliding in a part of tubular bead during the opening and closing movements can also be independent of the locking device. Indeed, the importance of such frames, even if they do not carry a lock, is essential for the convenience of use of the helmet according to the invention, their essential function is to allow full and wide opening movements of the collar.

This is why we must pull the metal loop 22 by compressing the spring 30 to that, the boss 21 then being in the middle of the metal loop 22, it does not obstruct the movement of the locking loop 26.
  • Two wings, formed by the metal loop 22 on either side of its axis 39 are bent so as to form two bosses 31 and 31 '( Figures 9 and 14) which, sliding while being elastically deformed on two branches of the locking loop 26, allow, when the metal loop 22 is pulled and that its bosses are located outside the locking loop 26 to form obstacles which, opposing the force of the spring 30, prevent the return of the metal loop 22 against the locking loop 26.
  • the locking loop 26 can bear against the extension 2, two tabs 27 and 27 'formed by this loop then pass through slots 32 and 32' and thus ensure the locking of the helmet in the closed position by being housed in grooves 34 and 34 'of the parts of locks 35 and 35' integral with each of the bead ends 1, when they are introduced into female cylinders 28 and 28 '- reinforced by metal inserts 38 and 38' - of the extension 2.
  • the verro uillage having been carried out, the user can pull the metal loop 22 towards the locking loop 26.
  • the metal loop 22 being integral with the locking loop 26, it becomes impossible to move the latter away from the extension 2, and, by the same token, to proceed to unlocking making it possible to open the helmet.
  • the user To open his helmet, the user must therefore pull the metal loop 22 until it comes out of the hook 21 and the bosses 31 and 31 'pass again outside the locking loop 26, then exert on the locking loop 26 an effort tending to move it away from the extension 2.
  • the flexible frame 4 partially shown is here an elastic metal element of the piano wire type; its central, rectilinear zone is introduced into a conduit 33 of the extension 2.
  • the two branches of the frame are bent then, over a length equal to the length of the cylinders 28 and 28 ' of the housing 2, are still rectilinear so as to confuse their axes with those of these cylinders in the areas where they pass through them.
  • the two branches of the frame 4 are bent according to a radius of curvature approximately equal to that of the bead in its open position, this so that, the unlocking of the bead having been actuated, they tend to automatically open said bead.
  • the total length of the frame is slightly less than the perimeter of the closed bead, its section is constant, its ends are only rounded to facilitate their sliding inside the bead.
  • the bead 1, made of molded rubber with the skirt 18 is, at its outlet from the mold, of single length for all sizes of helmets. By cons, the bead has a rilsan frame 36 having a different length according to each size of helmet.
  • the manufacturer at the time of assembly chooses the rilsan frame 36 of adequate length, introduces it into the bead 1 and fixes at each of its ends the bolt part 35, which part, tubular and whose central duct has a diameter equal to that of the rilsan frame, by screwing onto the rilsan frame 36 compresses the bead 1 which, thanks to its ends treated in thick rubber bellows, can undergo this compression without damage until reaching the chosen length, the latch parts 35 being screwed in fully. These lock parts are then blocked by hot pressing the ends of the rilsan frame 36 into grooves 37 provided for this purpose in part 35.
  • the rigid, sliding half-skirt in the variant of a retention system consisting of a single sliding rigid half-skirt mounted at the rear part of the base of the shell, the rigid, sliding half-skirt, extends - in the closed position - the base of the helmet shell about half of its perimeter; this half-skirt allows the helmet to open by sliding in a translational movement in a plane roughly parallel to that of the base of the shell, in a direction going towards the outside of the helmet; during opening, a stop device limits the amplitude of this movement in translation; when the helmet is closed, the upper edge of the sliding half-skirt is hooked, thanks to a complementary shape, to the lower edge of the shell; the areas of the surface of such a half-skirt capable of coming into contact with the neck or the base of the user's face are covered with padding.
  • a system of flexible blades each linked at one point to an extension of the base of the shell and capable of sliding inside a duct formed in each half-skirt provides the connection and the guiding between each sliding half-skirt. and the shell of the helmet or, conversely, a system of flexible blades integral with each sliding half-skirt ensures its connection and its guidance with the shell by sliding in conduits formed therein; a system of links articulated to one of the elements to be linked, for example the half-skirt, and sliding relative to the other element, namely the shell, to which they are linked, reinforces the connection between each half-skirt sliding and hull.
