Definitions

  • the present invention relates to a protective helmet for motorcyclists designed to be equipped with a double vision screen system of the kind described in patent FR-A-2,532,528.
  • the vision screen comes down to a transparent screen articulated on two lateral and opposite points of the external surface of the hull.
  • dismantling this screen requires the use of one or more tools.
  • a screen in the closed position, completely closes the corresponding cutout made in the shell and delimiting the useful field of vision.
  • the almost non-existent ventilation inside the helmet favors the formation of fogging on the screen in cold weather, and in hot weather ... that of sweat on the user.
  • we raise the screen we allow the air mixed with dust and insects to rush in an anarchic way inside the helmet where turbulence is created which is incompatible with comfort - notably the user's visual .
  • the aerodynamic resistance linked to the volume of the helmet which, applying a rearward action to it, requires the user to have to respond to it with a reaction towards the before.
  • the aerodynamic force pulling the helmet back is due less to the direct pressure of the air against the front face of the helmet than to the suction of the rear part of the helmet due to the turbulence of the air streams and to the resulting depression.
  • the helmet according to the invention proposes to remedy these defects by the use of a system of double vision screen adapted - according to a preferred and complete variant of the invention - to a specific shell.
  • one of the two screens is, in the closed position, integrated into the line of the hull and offers the particularity of being able to be raised, outside the hull, without however harming the aerodynamic qualities of this one.
  • the second screen whose height is, at least in its central zone, lower than that of the external screen, meanwhile, is raised inside the hull. The presence of this second screen combined with a judicious ventilation system makes it possible to fight effectively against the formation of fogging.
  • This ventilation system consists of an air intake made in the frontal area of the hull or the upper part of the exterior screen. To be effective, this air inlet must be associated with two outlets - of larger total section -, thus forming a low pressure system sucking the air inside the helmet. These outputs are openings made in the two lateral zones of the external screen, close to each of its ends. In order to increase the efficiency of the low pressure system by accelerating the circulation of air tangentially to these outlets, each end of the screen is fitted with a cover covering the air outlets, open towards the front and towards the rear, the section of the rear opening being the largest.
  • this ventilation system the whole of this ventilation system - the front air inlet opening below the upper edge of the interior screen - has the effect of forming a moving air film between the two screens, hence its effectiveness as an anti-fog, the air exhaled by the user being below the lower edge of the interior screen.
  • this system prevents the user from receiving cold air from the front air inlet directly into the eyes.
  • the height of the interior screen being sufficient to ensure eye protection, it allows good driving comfort for a user preferring to roll the exterior screen fully raised.
  • this short screen can be tinted and used or not at will and instantly with the external screen whenever the light conditions require it, the movements of the two screens being independent of each other, the interior screen being actuated by means of a member accessible by the user whatever the position of the exterior screen.
  • the interior screen is articulated on two lateral and opposite points of the shell located on the same axis perpendicular to the vertical longitudinal median plane of the helmet. The material axes carrying these joints are internal to the hull. This screen is raised by sliding between the shell itself and the external surface of the shell fitted for this purpose: recesses and possibly direct stratification or internal double shell. The method of attachment and articulation chosen allows disassembly and assembly easy and without tools.
  • This method of attachment consists of a cut other than cylindrical made at each end of the screen and emerging therein. These cutouts when setting up the screen engage on male parts of corresponding section linked to the internal face of the shell but free in rotation relative to the latter. The connection between the ends of the screen and the parts on which they engage is then comparable to that of a flat key with a screw head. This connection allows the rotation of the screen around a fixed axis relative to the shell. A combination of hollows and bumps formed between the surface of the shell and one of the moving parts and resting against it - the screen or the parts which carry it - ensures the rotational positioning of the screen: raised position, lowered and "disassembly".
  • a suitable elastic system pressing against the internal face of the screen at each of its articulations maintains the pressure between the other face of the screen and the part which carries it as well as possibly between this last part and the inner side of the hull.
  • Another combination of hollows and bumps between the screen and one of the cooperating parts ensures the translational connection of the screen relative to the shell.
  • the screen itself which, when it is positioned below its normal position of use, is freed from the nipple or boss ensuring its connection in translation relative to the shell, either by sliding on an inclined plane tending to move it away from the shell or away from it the part or part of part pushing each of its ends towards the shell, either that it has a groove or a rim in an arc of a circle, in or against which the nipple circulates , opening to the outside of the screen at the level reached by the nipple when the screen is in its disassembly position. Then simply remove the screen by pulling it out of the helmet.
  • the screen is operated by action on a lever extending on at least one side, towards the base of the shell, the part to which the screen is linked in rotation, or the screen itself. even.
  • the outer screen is, in the closed position, integrated into the line of the hull, its external surface is completely in the extension of that of the hull, forming no protrusion with it.
  • the opening movement then decomposes in at least two stages: the first, of apparent translation forward, away from the hull. Simultaneously, the ends of the screen are also detached laterally from the surface of the hull for easy subsequent lifting.
  • This advanced position of the screen is a position that can advantageously be taken to the screen to allow efficient ventilation and without turbulence, due more to the depression than to the direct action of the wind, inside helmet.
  • the screen can be raised according to a rotational movement bringing it opposite the surface of the shell against which it will be pressed, by a new movement in translation, against the shell.
  • the screen can also be raised, above the frontal zone, up to the upper part of the shell and kept a few millimeters from the surface thereof, slightly inclined relative to it so as to form an aerodynamic flap whose cross section of the air inlet between the internal face of the screen and the shell is less than that of the outlet towards the back.
  • the screen thus raised behaves like an aerodynamic flap, the speed differential between the air streams drawn in and laminated between the shell and the screen on the one hand and the air flow passing over the screen on the other hand, having the effect of repositioning the air streams against the rear of the hull, thereby limiting the surface thereof subjected to vacuum.
  • Such an aerodynamic flap can also, independently of the vision screen, be adapted to a helmet and treated in the form of a fixed adjustable or removable hoop which would have the advantage of being able to fulfill its role, even the screen being in position. lowered.
  • such a hoop is designed as an outer double shell open towards the front and towards the rear and inside which the screen can possibly be housed in the raised position.
  • the external screen in order not to be aerodynamic discomfort when it is in the raised position, is characterized in that its internal face offers a profile identical in all respects to that of the external surface of the hull in the area against which it can be pressed in the raised position.
  • the radius "R" of the external frontal curve of the shell is equal - or less, in the value of a functional clearance - than that of the curve of the internal face of the screen in this same plane.
  • the "X" axis is fixed relative to the screen, movable relative to the shell, perpendicular to the vertical longitudinal median plane of the helmet and passing through the mobile point of this plane, center of the circle of radius "R” generating the internal surface of the screen, is in a position "X"'fixed relative to the shell, when the screen is in the closed position.
  • This "X” axis is not necessarily confused with the "Y” axis parallel to "X”, but fixed relative to the shell and passing through the point of the vertical longitudinal median plane of the helmet which is also the center of the circle with the same radius "R” generating the external surface of the hull in its frontal area.
  • the vision screen is itself articulated by each of its ends along an axis "U” - parallel to "X” and at "Y” - on an intermediate part - generally a disc or rod - itself articulated on the hull according to an axis of rotation "V" parallel to "U” but not confused with it.
  • This part optionally bears on its face against which the screen comes to bear, a second material axis which can, during movements of the screen, circulate in a groove made in the screen.
  • This axis may or may not coincide with the "V" axis depending on the variant embodiments.
  • this articulated assembly allows by a rotational movement of the intermediate piece around its axis V, to bring the screen still in the lowered position in its advanced position of use relative to the shell, in a movement comparable to that of a connecting rod.
  • the quality of this translational movement is improved if the "U" axis is engaged in a groove made in the screen in place of an adjusted cylindrical bore. Then, by a rotation of the screen around the axis "U”, with respect to the intermediate piece, one passes from the lowered position to the raised position.
  • the screen By a new movement of rotation of the intermediate part around the axis "V", the screen is pressed against the shell thus bringing the axis "X” in coincidence with "Y".
  • the position of "X” is further modified by acting on the rotation of the intermediate piece around the "V” axis and of the screen around the "U” axis.
  • the separation of the ends of the screen from the lateral zones of the hull is ensured by a combination of inclined planes between two surfaces which are movable relative to one another and resting on one another : intermediate-shell part, intermediate-screen part or screen-shell.
  • one of the material axes joining the screen to the shell according to "V" or "U” is equipped with a helical system cooperating with the bore in which it is introduced.
  • the maintenance and the guiding of the latter are completed by the action of one or more studs integral with the shell or with the intermediate piece, fixed relative to this support, around which are guided lights or grooves made in the screen and acting as cams limiting the amplitude of the different movements and according to which the rotational movements of the intermediate piece around the "V" axis and of the screen around the "U” axis are decomposed or simultaneous.
  • a cover, open towards the front and towards the rear - the screen being in the closed position - is fixed on each end of the screen, above the side air outlets, which can be combined with a "cam groove” useful for guiding the screen.
  • Such a cover, fixed relative to the screen moves with it relative to the shell. During its installation, it can, by clipping, above the screen, around the head of the material axis "U" - if it passes through a cylindrical bore of the same diameter practiced in the visor - used for easy and removable attachment without tools, of the visor on the intermediate piece and therefore on the helmet.
  • each end of the screen is linked, permanently or removable, to a flat part extending it, through which the bores, grooves, lights or functional bosses normally appearing are practiced. on the screen itself.
  • This in particular in order to have a tool - mold for manufacturing the screen - simplified.
  • each end of the screen is engaged in a flat piece extending it and has a possibility of movement in translation relative to this piece through which the grooves are also made, functional lights or bosses normally appearing on the screen itself.
  • a combination of inclined planes between two surfaces bearing against one another and movable with respect to each other then makes it possible, during the translational movement of the screen relative to the part extending it, to take off the screen from the lateral zones of the helmet in order to make its lifting movement - by rotation around the "U" axis of the pieces extending each end of the screen - easy.
  • the shell in its frontal area, just above the edge upper part of the external vision screen - in the lowered position - sees its external surface arranged so as to form a series of grooves-like grooves - or reliefs substantially parallel to each other and with the upper edge of the vision screen, each extending over a length at least equal to that of the vision screen.
  • these "rain-proof waves” are - in the vertical longitudinal median plane of the helmet - in relief with respect to the general curve of radius "R” in the frontal area of the hull, they can constitute a device making it possible to give the shell in the area near the upper edge of the vision screen in the closed position a local radius of curvature of the value of "R” increased by the material thickness of the exterior screen.
  • the exterior screen - the interior face of which retains a radius of curvature of value "R" equal, apart from the functional clearance, to that of the hull in the area, above the rain system, against which it can be placed in the raised position - may, while offering, in the closed position the appearance of a screen completely integrated into the line of the hull, have - as in the alternative embodiment according to which the external screen is not, in the closed position, not integrated into the hull line - its "X" axis in a "X"'position where "X"' is confused with "Y".

  • Such a single double-walled screen is molded or formed from two thermoformed or curved screens assembled together by being separated by a spacer at their upper edges and at their ends.
  • X is the theoretical axis, perpendicular to the vertical and longitudinal median plane (p) of the helmet, passing through the point of this plane which is also the center of the circle of radius "R + j" corresponding to the radius of curvature, in the plane (p), of the internal face of the external screen.
