Definitions
- the present invention relates to a protective helmet for motorcyclists designed to be equipped with a new vision screen system, and this vision screen system itself.
- the vision screen boils down to a transparent screen articulated on two lateral points and opposite the external surface of the shell.
- 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 promotes 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 the comfort - notably visual - of the 'user.
- the aerodynamic resistance linked to the volume of the helmet which, by 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 resulting depression.
- the helmet according to the invention proposes to remedy these faults by the use of a double vision screen system 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 the height of which 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 rear opening section 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 film of air moving between the two screens, where its effectiveness as qu'antibuée f exhaled air by the utilisa ⁇ tor being below the lower edge of the screen interior.
- this system prevents the user from receiving cold air from the front air inlet directly into the eyes.
- the hau- the interior screen being sufficient to provide protection. eyes, it allows good driving comfort for a user who prefers to roll up the completely raised exterior screen.
- this short screen can be tinted and used, or not, at will and instantaneously, with the external screen each time the light conditions require it, the movements of the two screens being independent one on the 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 proper and the external surface of the shell provided for this purpose: recesses and possibly direct stratification or internal double shell. The method of attachment and articulation chosen allows easy and tool-free dismantling and assembly.
- This method of attachment consists in a cut other than cylindrical made at each end of the screen and emerging therein. These cut-outs during the setting up of 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 operation of the screen is done 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 himself.
- the external screen in the closed position, integrated into the line of the shell, its external surface is totally in the extension of that of the shell, forming no projection with it.
- the opening movement then breaks down into at least two stages: the first, of apparent forward translation, the distance 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 hull.
- the screen can also be raised, above the frontal zone, up to the upper part of the shell and kept at a few millimeters. of the surface thereof, slightly inclined with respect to it so as to form an aero ⁇ dynamic flap whose cross section of the air inlet between the internal face of the screen and the shell is lower than that of the output- towards the rear.
- the screen thus raised behaves like an aerodynamic flap, the differential speed 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 an adjustable or removable fixed hoop which would have the advantage of being able to fulfill its role, even the screen being in lowered position.
- 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 in the raised position, is characterized in that its internal face offers an dental profile 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 vertical longitudinal median plane of the helmet in particular, where the radius "R" of the external frontal curve of the shell is equal — or less, of 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 fixed by relative to the screen, movable relative to the shell, perpendicular to the vertical longitudinal mid-plane of the helmet and passing through the movable 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.
- the vision screen is itself articulated by each of its ends along an axis "U” - parallel at "X” and at "Y” - on an intermediate piece - generally a disc or link - itself articulated on the hull according to an axis of rotation "V" parallel to "U” but not melted with it.
- This part optionally bears on its face against which the screen comes to bear, a second material axis which, during the movements of the screen, can circulate in a groove made in the screen. or not confused with the "V" axis.
- this set-ar ⁇ ticulated allows by a rotational movement of the intermediate piece around s on axis V, to bring the screen still in the lowered position in its advanced position of use relative to the shell, according to 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- placed in the raised position.
- the screen By a new movement of rotation of the intermediate piece 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 which bear on one another : O intermediate piece-shell, intermediate piece-screen 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 the intermediate part, fixed relative to this support, around which are guided by the lights or grooves made in the screen and forming cams limiting the amplitude of the different movements and as a function of which the rotational movements of the intermediate piece around the "V" axis and the screen around the axis "U” are de ⁇ composed 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 lateral air outlets, which can be combined with a "groove-cam" useful for guiding the screen.
- Such a cover, fixed relative to the screen moves with it relative to the shell. When put in place, 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 screen - used for easy and removable attachment without tools, of the screen on the intermediate piece and thereby 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 are formed. normally shown on the screen itself.
- each end of the screen is engaged in a flat piece extending it and has a possibility of movement in translation relative to this part, through which are also formed the grooves, lights or functional 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, to extend it.
- the shell in its frontal area, just above the upper edge of the external vision screen - in the lowered position - has its external surface arranged so as to form a series of hollows - 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.
- the outer screen -whose inner face retains a radius of curvature of value "R" equal, apart from the functional clearance, to that of the shell in the area, above the rain system, against which it can be pressed in the raised position - can, while offering, in the closed position the appearance of a screen completely integrated in the line of the shell, have - as well as in the alternative embodiment if - Ion which the external screen is not, in the closed position, integrated into the hull line - its "X" axis in a "X"'position where "X"' is confused with "Y".
- any vision screen used alone on a helmet but is present in the form of a single screen with double walls - separated by sufficient space to allow the circulation of an air film- joining at the upper edge of the screen, not joining

- "X" is an axis movable relative to the shell, fixed relative to the screen with which it moves.
- V is the axis of the hull, parallel to "X 1 " and "Y”, according to which the intermediate parts between the outer screen and the hull are articu ⁇ lated to the hull, on either side of it.
- FIG. 1 makes it possible to observe the turbulence which forms both at the rear and when the screen is raised at the front of a helmet fitted with a vision screen of known type.
- Figure 2 shows the movement of a screen 1 according to the invention. From the closed position (a), it passes, thanks to the action imparted to the operating member 3 in its advanced position (c). From there, by a rotational movement, it arrives at position (d). Subjected to a force F, it can then be pressed against the shell 2 of which it marries the profile - position (e) -. A force F applied to each end of the screen makes pass from (e) to (f), position in which it takes the inclination 'required to fulfill the function of aerodynamic flap which after - a new rotation, it occupies in position (g).
- Figure 3 illustrates how the dual vision screen system works in its anti-fog function.
- the air entering the interior of the shell through the orifices is blocked between the two screens and sucked towards the lateral zones by the effect of the depression due to
- the elastic systems practiced during the molding of the part in the form of tongues 11 in the internal flank of the part, maintain the pressure between the screen and the other flank of the part "A combination of hollows and hemispherical bosses 12 between the surface and the shell 0 cc of the part 9 bearing against the shell / itself ensures the rotational positioning of the screen in relation to the hull.
- the interior screen In the raised position, the interior screen is housed between the shell 2 and the double shell 13.
- the translational positioning of the screen relative to the shell is provided by the boss 14 formed on the surface. 5 dull hull and around which circulates the groove 1 made in the screen.
- This boss 14 also has the function of limiting the ampli ⁇ tude of the rotational movement of the screen.
- the axis "U” belonging to the part 21 passes through a light in an arc da circle 22 of the screen 1.
- the axis "U” is merged with the axis "X” , shown here in its "X” position.
- the illustrated helmet represents a variant embodiment in which the screen 1 is in the closed position (a) - completely integrated into the line of the shell, including in its lateral zones, a combination of inclined planes 26 -26 '

- the cable 37 which is linked to it passes around an axis -or a small pulley 38- integral with the internal surface of the hull 2, before joining - by first circulating inside the cas ⁇ that, then in a groove 41 formed outside the hull and itself joining the counterbore 42 used to house the part 21 - the pi ⁇ this 21 at the periphery of which it circulates in a groove 43. to be fixed therein by introduction of the cylinder 40 - set on it - in the bore 40 ' Q e the piece 21.
- each end of the screen is fixed on the piece 21 or 21 * by means of two screws 45 ⁇ 46 on the axes "U" and 23. It is accessible after removing the side covers 1.
- the groove 47 formed in the wounding of the tubular axis 17 of the shell 2, wider than the elastic ring 25 allows the part 21 to have relative to the shell 2 sufficient freedom in translation to ensure the separation of the ends of the screen necessary for easy lifting thereof.
- FIG. 14 shows another embodiment of an external screen 4i according to the invention.
- the screen 49 is articulated on the part 51 along a cylindrical axis "U" coincident with "X" passing through a cylindrical cutout of the same diameter, apart from the functional play, practiced in the screen.
- the lifting movement is simpler here, the raised position being the only position (e).
- FIG. 16 shows another variant in which the screen 57 pro ⁇ prement said at its ends extended by parts 64. These are the parts 64 which receive the axis "U” and the groove 59 cooperating with a stud 58 of the shell to guide the screen.
- the screen 57 is detachably linked to the part 64 by these ends each housed in a counterbore 60 of the part 64, and pierced with cutouts 62 in which the bosses 66 of the cover 67 engage, itself fixed on the piece 64, above the screen, by three screws 65.
- the screen is also used here to ensure the connection between the piece 64 and the piece 85 by clipping one of its cutouts in a groove practi ⁇ placed around the axis "U" above the part 64.
- the screen changes from position (a) to position (e) due to rotation of the part 85 around the axis "V” at an angle close to 3 ° 0, and not as in the cases studied previously se ⁇ lon an angular sector passing the axis "U” from the position "X '" to the position "Z” and vice versa.
- FIG. 18 shows another alternative embodiment of a screen ex- tieur 68 in which each end of the screen 68 itself is engaged in a counterbore 77 in one piece 75.
