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. Apart from the fact that such a helmet does not offer protection of the lower part of the chin, 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 helmet shell being clearly offset relative to the transverse median plane of the user's cranial boot, the helmet will tend, during an impact, to tilt from back to front in a rotational movement around an axis passing substantially through the ears of the wearer of the helmet.
  • Such a device cannot therefore prevent the helmet from leaving the head during a simple shock or followed by twists and turns.
  • 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 chinstrap 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 making it possible to actuate the locking device are easily accessible from the outside of the helmet and can, in the event of an impact, come into contact with a roughness of the ground, 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 sweaters or jackets with a stand-up collar, which is common for a motorcyclist - is difficult because of the amplitude of the movement described by the ends of each half-skirt when they are opened or closed.
  • the presence of small tabs, fitted with a hook, secured to each end of the half rear skirt, makes the operation even more delicate, since it is common to tear a garment - mainly a knitted fabric - by inadvertently engaging one of these hooks in a mesh of said garment.
  • the use of a rigid skirt makes it necessary to provide protection of the user's neck against contact with the edge of this skirt by a shock absorbing system and a thick padding of flexible foam inserted between it and the wearer's neck. helmet. Therefore, the perimeter of the cutout drawn by the edge of the skirt itself is much greater than the perimeter of the neck that it is supposed to surround.
  • Retention is therefore effectively ensured - mainly at the front of the helmet - only by the padding of flexible foam resting by its upper face against the lower face of the user's chin,
  • the slightest shock subjecting the helmet to a couple is enough to deform this padding so that the user can see his helmet, if not detach from his head, at least tilt back and forth until the retention system comes to bear against the underside from his nose.
  • an uncomfortable and dangerous situation to say the least, if the person is wearing a pair of glasses, the upper part of the latter then crashing against his browbones ...
  • helmets of this type cannot take advantage of 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 designed so that the metal buckle equipping the chin strap of all helmets can be hung there ordinary protection.
  • This system is not a foolproof efficiency, since it is easy, for a possible thief, to cut the 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 chinstrap - ie without attachment loop - cannot use the anti-theft hook with which his motorcycle is nevertheless fitted, and must purchase a additional, expensive, heavy and bulky anti-theft accessory, generally consisting of a large chain or metal loop passing on the one hand around the chin portion of the helmet to be protected and on the other hand around a fixed part of the motorcycle.
  • the helmet object of the invention benefits from an improved securing device which, according to the variant envisaged, makes it possible to avoid all or part of the defects inherent in the prior techniques and ensures that it can fully fulfill its protective role of the cranial boot, whatever 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, concentric bead. only with the opening delimited by the lower rim 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 extensible.
  • 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 detachable (unlocking) from the end of the section against which it comes to bear during locking (this in order to - allow the opening of the collar which 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 monobloc and split in a single point (flexible bead)
  • the two ends determined by this rupture come to bear against one another and are held there by a locking system (closing of the collar) and - after having been unlocked - can be moved away from one the 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 bead is flexible, summed up for example with a textile or leather strap, flat or rolled.
  • the bead itself only exists along a part of the perimeter of the collar, the complementary part of said collar being able to be a rigid skirt - mobile or fixed - fitted with padding, or only part of the padding inside of the helmet extending towards the base of the shell and towards the inside of the helmet forming, for example, a neck cushion at the back of the helmet.
  • the bead portion itself can: be summed up, for example, with two independent sections of bead when they are in the open position, and joining end to end, or on either side of an extension of the base of the hull, in the closed position. These bead portions are then linked or articulated by their other ends to an extension of the base of the shell, or to the ends of the neck cushion with which they are associated.
  • the bead is rigid in at least two parts each articulated along a vertical axis carried by an extension of the base of the shell.
  • the opening of these bead portions can be made automatic by the action of elastic devices such as springs tending to cause this opening as soon as the unlocking is actuated.
  • each of the bead portions is extended, optionally over its entire length, by a rigid veil joining the base of the helmet shell and which, thanks to a form complementarity, can be hung there when the helmet is locked in closed position.
  • the flexible elements mentioned above are then considered to be non-existent.
  • the ends of two neighboring sections can also come to bear - or be articulated - on either side of a rigid intermediate piece integral either with an extension of the hull, or with a rigid articulated piece 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 ex upper end at the base of the shell.
  • the end of each of the sections if it has no articulation cooperating with the end of another section carries a bolt part cooperating with a complementary part secured to the end of the neighboring section or of the intermediate piece between it and the end of the neighboring section.
  • the bolt part secured to one end of the section can be carried by one end of this flexible core.
  • a flexible reinforcement also be / - generally by its center or its end - of an extension of the hull, or of a rigid part articulated at the base of the hull or of a set of parts rigid hinged together and articulated at the base of the hull, or a flexible piece linked by its upper end to the base of the hull.
  • the end or ends of this frame are engaged in a tubular conduit formed longitudinally in a portion of bead and opening out at the end thereof, the bead can thus slide around the frame during the opening operations and closing.
  • Each free end of such a frame carries a latch part cooperating with a complementary part, integral with the end of the bead section - or of the intermediate piece - against which the other end of the section which it crosses right through. part, comes to bear when closing.
  • each free end of such a frame joins - the helmet being closed - the end of another frame inside the same bead.
  • each of these frame ends carries an identical bolt part cooperating with a complementary part secured to the bead and allowing the connection between these two ends.
  • the lock can be a cylindrical piece, chamfered and carrying a circular groove causing a reduction in its diameter over part of its length.
  • This cylinder integral with one of the parts to be tied, is introduced when the helmet is closed, in a complementary hollow cylinder formed in the other piece to be linked, the side of this hollow cylinder has a light perpendicular to its axis. , through which passes a tongue - possibly pushed by a spring - whose end directed towards the inside of the cylinder is a semicircular cut whose axis is parallel to that of the cylinder and the diameter appreciably equal to that of the part of the full cylinder in the area where it is reduced by the groove.
  • 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 flexible frame slides in the tubular bead passing through a latch part, which is also tubular, secured to the bead end and through the complementary latch part, which is also tubular, integral with the same articulated extension of the base of the shell as the frame itself, mounted concentrically with this part of the lock.
  • the flexible frame is secured to one end of the bead, and slides in another part of the bead, the articulated extension of the shell then being eliminated.
  • each flexible frame, guide element consists of telescopic strands.
  • the flexible reinforcement is integral with an extension of the shell consisting of several rigid parts articulated together and articulated at the base and at the front of the helmet shell, and in the event where in the event of a rear impact, the play of the joints does not allow, the various articulated parts being stretched as far as possible towards the inside of the helmet, to have a backward movement of the whole of the collar formed by the bead sufficient to avoid the danger of rupture of the spine by impact of the neck against the rear part of this collar, at least one of the articulated parts is. formed of two parts or telescopic blades that can stretch by sliding or sliding of one on, or in, the other. A stop device prevents the separation of these two parts which are partially free in translation and a spring allows, apart from any tensile force violent, to keep them in the unstretched rest position.
  • connection between the bead and the helmet shell, except in the particular case described above, is carried out by one or more flexible elements.
  • this element is a veil, flexible or elastic extending the base of the helmet shell, this veil -which may be solid or perforated- is linked, by its upper part, to the base of the helmet shell either during its molding (for a molded rubber veil) either by stapling or wedging complementary shapes of the hull and the veil, or by pinching two lips of the upper edge of the veil on either side of the lower edge of the hull , kept applied against it by complementary parts - for example two flexible blades - one exterior, the other interior to the helmet, circulating at the base of the shell along its entire circumference and linked together by rivets passing through the through orifices made in correspondence through the two blades, the two lips of the veil and the rim of the hull, or by any other process capable of providing an effective - dismountable or permanent - connection and capable of withstanding significant breakout forces.
  • the veil may be a form extending the bead obtained during molding thereof.
  • the connection between the bead and the lower edge of the veil can be carried out by any form and method capable of ensuring an effective - dismountable or permanent - connection, and capable of withstanding significant tearing forces.
  • the movement in which the bead and the veil deform elastically in order to allow opening of the helmet is more or less complex.
  • the user having carried out the unlocking he applies to the bead -or to each bead portion- a torque tending to cause its overturning towards the outside of the helmet.
  • the veil generally works in compression - in the zone where the force is applied and in extension in the zones distant from this point.
  • the opening movement can also, more simply, take place in a single plane, parallel to the base of the shell and passing through the bead, the latter being simply open, and the two branches delimited by this opening kept apart from each other.
  • This movement can still have as many variants as there are types of possible realizations, its nature, its quality and the planes in which it develops being influenced by the choice of a true position of equilibrium other than that closed, by flexibility and. the elasticity of the bead, by the presence of cuts or missing parts at the level of the veil or the bead, etc ... Indeed, so that the dispesitif can be maneuverable without much effort, the veil must be split high down at least once. It can also be split into two points around its circumference.
  • Each of the slots dividing the veil and the bead can be replaced by the pure and simple removal of a certain portion of the bead alone, of the veil alone, or of the veil and the bead.
  • the elastic veil can also be reinforced punctually, in the areas where it will not have to work in extension, by one or more flexible but non-stretchable elements such as textile ribbons or by inclusion of textile or metallic threads connecting the upper part of the skirt (base of the helmet shell) at its lower part (bead) along a path that cannot be straight or strictly vertical.
  • each interruption of the flexible veil constituting the skirt is reinforced by an increase in its thickness - for example according to the shape of a cylindrical rod. This thickening, if it does not determine a rectilinear contour, is itself reinforced longitudinally with a wire or a small metallic cable embedded in its center.
  • the flexible veil in particular if it is made of rubber, extends outside the shell over the entire surface thereof.
  • the helmet thus produced improves its aesthetic qualities and shock absorption. So the outer surface of the co that and objects which may come into contact with it, in particular the body of the motorcycle, will no longer have to undergo the damage that such contacts generally cause them.
  • connection between the shell of the helmet and the bead is provided by at least two flexible but non-stretchable elements such as textile ribbons or leather straps.
  • connection between the shell of the helmet and the bead is provided jointly by at least one non-stretchy flexible element and, at least along part of their perimeters, by one or more flexible and elastic sails, each of these sails can be reinforced punctually by one or more flexible but not extensible elements.
  • the height positioning of the bead relative to the base of the shell is adjustable.
  • flexible but not extensible elements such as textile ribbons to operate the connection between the bead and the shell, it is easy to equip these elements with metal loops -or other similar adjustment systems- of the type used on conventional chinstrap.
  • the perimeter of the bead in its closed and locked position is adjustable so as to be able to adapt to the morphology of each user, this in the case where the external padding of the bead is not sufficient to compensate for these differences in conformation.
  • the entire bead which, thanks to the flexibility and possible elasticity of the element or elements which connect to the shell of the helmet can move, thus ceasing to be concentric with the opening delimited by the lower edge of the shell.
  • a damping role, supplemented by the elasticity of the padding of the bead is thus ensured without the perimeter of the bead and therefore the quality of the retention which it ensures being modified.
  • the bead if it is linked to the shell by one or more elastic elements absorbed, here again, the shock by moving towards the low, while continuing to fully ensure the retention of the helmet thanks to its non-extensibility and the constancy of its perimeter.
  • the bead is made of molded rubber, without inextensible framework.
  • the flexible skirt is extended in each of its two lateral areas - or front sides - beyond the normal outline - marked by the cylindrical rod described above. 'one of its days or at its end, by a small flexible veil linked on the one hand to the base of the shell and on the other hand to the bead as well as to the flexible skirt but whose height - greater towards the before that backward-, is of greater value than that of the rest of the skirt in the area where it is bound to it.
  • the pipe emerging at the base of the shell of the helmet is formed on the external surface of the shell, then, crossing the latter, extends towards the top of the helmet by several other pipes formed on the internal surface of the shell or the outer surface of the foam comfort padding covering the shell.
  • the pipe opening at the base can also be formed on the internal surface and at the base of the cap to open as close as possible to the air intake concerned. The air, along these channels is thus distributed harmoniously along the entire internal surface of the helmet padding.
  • flaps made of rigid or semi-rigid materials slide between the internal face of the helmet shell and the outer face of the shell and can be lowered below the lower edge of the shell to act as a barrier and air deflector between the base of the helmet shell and the bead in areas where the flexible skirt ensuring the - connection between the bead and the base of the helmet shell is perforated or nonexistent.
  • This loop can also pass, independently of the hinge through two holes, or a conduit formed in the shell of the helmet.
  • hole in the shell of a helmet also says modifications of a very expensive mold, initiation of rupture of the shell thus arranged, and problems of tightness, both in air and in water, of the said hull. Therefore the preferred embodiment of the lock according to the invention is characterized because of its utili- s p tion to replace a hinge pin existing, the price of this axis thus saved coming from elsewhere as a deduction from the price of the anti-theft loop.
  • this anti-theft device is a system of two loops, one of which, also forming a hinge pin, is linked to the other by a swivel.
  • this second loop free to rotate, can be attached to the helmet lock provided on any motorcycle, while keeping the helmet the possibility, regardless of the direction of the axis of the motorcycle lock hook, to be oriented. with respect to it so that any rain that occurs during a stop cannot fill it with water, which would be the case if the base of the helmet were turned towards the sky.
  • an appropriate system allows this set of loops to be immobilized and pressed against the external surface of the helmet when not in use as an anti-theft device.
  • the loop or all of the two anti-theft loops can be clipped onto -or in- a relief -or hollowed-out form of the helmet shell or of the rigid part articulated thereto. .
  • the anti-theft device thus produced, not only eliminates the defect of helmets provided with a securing device without chin strap compared to ordinary helmets, but improves the device since the anti-theft loop is not linked to the helmet by an easy chin strap section.
  • the anti-theft loop system also serving as a hinge pin is adapted to the helmet object of the invention in order to fulfill the quadruple axis function hinge, anti-theft loop, locking system and safety locking device of said locking.
  • the anti-theft loop system may fulfill, in addition to its initial functions of the hinge pin and anti-theft loop, only a third function of the locking system, or of the device for blocking the said locking.
  • the bead if it is a single piece, tubular and molded in rubber, has its ends treated as a thick rubber bellows.
  • a frame also tubular, in rilsan or other semi-rigid or flexible material but resistant to tensile and shearing forces, is then introduced into this tubular bead, each of its ends, threaded, receives then the bolt parts which also have longitudinal stops on this frame and which, bearing by their rear faces on each end of the rubber bead, allow during their assembly, to compress more or less, depending on the length of the frame on which they are fixed, the bead.
  • the shell is extended towards the base and towards the center of the opening determined by this base by a rigid skirt in two parts, at least one of which can slide in a plane parallel to that of the base of the hull, towards the outside thereof.
  • a sufficiently thick padding covers this skirt in all the areas of its surface liable to come into contact with the user around the neck of which it forms a collar.
  • the connection between each sliding half-skirt and the base of the helmet shell is reinforced, in the closed position, by hooking, along its entire length, the upper edge of these half-skirts to a shape complementary to the lower edge of the shell .

  • Two small hairpin springs - not shown -, mounted around this axis at each of its ends and bearing on the one hand on the two main branches of the loop 26 and on the other hand against the part 2 maintain the set of loops 22 and 26 pressed against the part 2.
  • the spring 30, shown in thin lines in FIG. 9 - and not shown in FIG. 14 keeps the loop 22 in abutment against the loop 26.
  • the loop 22 therefore abuts on the top of the boss 21, thus preventing the loop 26 from coming into full support in the grooves 20 provided for this purpose on the part 2. This is why one must pull the loop 22 by compressing the spring 30 so that, the boss 21 then being at middle of the loop 22, it does not obstruct the movement of the loop 26.
  • Two wings, formed by the loop 22 on either side of its axis 39 are folded so as to form two bosses 31 and 31 '( Figures 9 and 14) which, sliding while being elastically deformed on two branches of the loop 26 allow, when loop 22 is pulled and its bosses are outside of loop 26 to form obstacles which, opposing the force of spring 30 prevent the return of loop 22 against the loop 26.
  • the loop 26 can come to bear against the part 2, the two tabs 27 and 27 'formed by this loop then pass through the slots 32 and 32' and thus ensure the locking of the helmet in the closed position in coming to be housed in the grooves 34 and 34 'of the parts of locks 35 and 35' integral with each of the ends of the bead 1, when they are introduced in the female cylinders 28 and 20 '-reinforced by metal inserts 38 and 38'- of the part 2. Having locked, the user can pull the loop 22 towards the loop 26. The two bosses 31 and 31' pass again inside the loop 26, and the loop 22 engages in the hook formed by the boss 21, the spring 30 preventing it from coming out without the intervention of the user.
  • all of the loops 22 and 26 can be moved away from the part 2 and the loop 22 can be passed through the anti-theft hook with which all modern motorcycles are fitted, so as not to have to carry the helmet with you.
  • the flexible frame 4 shown partially in FIG. 15 is here an elastic metallic element of the piano string type; its central, rectilinear zone is introduced into the conduit 33 of the part 2.
  • the two branches of the frame are bent then, over a length equal to the length of the cylinders 28 and 28 'are still straight so as to confuse their axes with those of these cylinders in the areas where they cross them.
  • the two branches of the frame 4 are bent according to a radius of curvature substantially equal to that of the bead in its open position, so that, the unlocking of the bead having been actuated, they tend to automatically open the 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.
  • the rilsan frame 36 has a different length depending on each size of helmet. In fact, the manufacturer, at the time of assembly chooses the armature 36 of adequate length, introduces it into the bead 1 and fixes at each of its ends a bolt part 35.
  • the bead sail assembly thus completed, is then mounted on the hull.
  • the helmet is then ready to operate.
