    专利说明:

    The invention relates to a sports helmet with enhanced ventilation and demisting capacities.
    The invention relates more particularly to a helmet for board sports and, in particular, winter sports such as downhill or ski touring, cross-country skiing, surfing or sledding.
    The helmet of the invention can also be used for the practice of cycling, cycle tourism or mountain biking.
    PRESENTATION OF THE INVENTION The protective helmets used for the practice of sliding sports and, in particular, winter sports, are intended to protect the skull of the sportsman in the event of a fall or impact against obstacles.
    Given the relatively low temperatures prevailing in snowy areas and / or at altitude, helmets also have thermal insulation properties against the cold outside environment.
    In order to effectively perform these various functions, traditional helmets include a rigid outer shell containing an inner cushioning that is damping and thermally insulating.
    In addition and in order to avoid excessive heating of the skull, these helmets are generally provided with means ensuring the escape of the hot air produced at the level of the head due to the physical efforts of the user.
    These evacuation means comprise a ventilation circuit opening to the outside on the upper face of the helmet via conduits delimited between slots made through the rigid outer shell and the inner shell.
    Some helmets are equipped with an adjustable closure system of the ventilation circuit which allows the user to adjust the temperature inside his helmet according to the circumstances, by displacement, for example by translation , a shutter.
    [0010]
    Such helmets are described, in particular, in patents
    US 6904618 and
    US
    8683617. In these patents,
    The shutter system consists of a plate arranged between the inner shell and the outer shell and which is capable of being moved by the user in translation by a maneuvering lug, accessible from
    The outside of the helmet, to close the ventilation circuit slots.
    Furthermore, it is very common for users of sports helmets to also wear glasses or a screen mask to avoid the harmful effects of speed, rain, cold, wind and / or sun on the vision of the environment.
    [0012]
    The masks generally have an upper edge which is lined with a strip of porous foam and / or orifices communicating with the outside in order to limit the phenomena of condensation inside the mask.
    However, the joint use of a helmet and a mask promotes the appearance of fogging (water vapor) inside the mask due, in particular, to the fact that the lower edge of the helmet tends to hinder the evacuation of fogging. Thus, some helmets are equipped with integrated means facilitating the demisting of the mask.
    These demisting means comprise a ventilation circuit housed in the helmet and communicating with the interior volume of the mask via the foam strip or the orifices. The communication is established by suction outlets, arranged on the lower edge of the inner cap opposite the upper edge of the mask and opening to the outside on the front face of the helmet via channels and ejection openings formed on its outer shell.
    Such helmets are described, in particular, in US patents 2011/0167541 and US 5915537.
    However, the means for evacuating hot air and the demisting means provided on existing helmets are generally independent. Indeed, the helmet ventilation circuit and the mask ventilation circuit are designed so that they are necessarily separate and can only be isolated from each other on known helmets.
    The present invention aims to optimize the ventilation and demisting capacity of helmets by coupling the circuits specific to these functions so that the respective flow rates of the hot air discharge flows and ejection of water vapor are significantly increased by synergistic effect.
    This object is achieved, according to the invention, by means of a sports helmet comprising an outer shell and an inner shell characterized in that said shell and said shell define between them, on the one hand, a circuit d ventilation intended for the evacuation of hot air, delimited between slots made, respectively, through the inner shell and the outer shell and, on the other hand, a ventilation circuit intended for demisting a independent vision, delimited between suction openings provided on the front part of the helmet and ejection openings provided on the outer shell, said helmet further comprising an adjustable shutter making it possible to modify the air flow of the circuit d ventilation and ventilation system reversibly.
    According to an advantageous characteristic, the shutter connects the ventilation circuit to the ventilation circuit.
    In a first variant, the shutter comprises a longitudinal opening.
    According to another characteristic, the shutter comprises a maneuvering stud which projects through the outer shell.
    According to another advantageous characteristic, the adjustable shutter comprises an axial tongue provided with a longitudinal opening and connected, on either side, to two arms each carrying a flap forming a valve between the aeration circuit and the ventilation circuit.
    According to a first embodiment, the aeration circuit comprises, on the cap, a central cavity and at least two lateral cavities, said cavities receiving said adjustable shutter and communicating with said slots.
    According to another embodiment, the ventilation circuit comprises at least two lateral channels formed on the cap between the suction outlets and said lateral cavities of the ventilation circuit with which they communicate via a duct.
    According to another characteristic, the axial tongue slides in the central cavity while the flaps pivot in the lateral cavities by movement of the arms under the action of the tongue, between an isolation position of the ventilation circuits respectively and ventilation and a communication position in which the side channels of the ventilation circuit open, via the conduit, into the side cavities of the ventilation circuit.
    According to yet another characteristic, the exhaust vents of the ventilation circuit communicate with said channels upstream of said duct.
    Preferably, the ventilation circuit channels have a narrowed section from upstream to downstream.
    According to a specific variant, the arms have a curvilinear profile and slide in circular guide grooves formed between the central cavity and the lateral cavities of the cap.
    According to another variant, the flaps are produced on rods connected to said arms and fixed in a rotary manner in said lateral cavities.
    Preferably, the shutter is made in one piece consisting of the tongue, flexible arms and rods carrying the flaps.
    According to a preferred embodiment of the invention, the ventilation circuit comprises, on the one hand, at least one axial slot of the cap coming opposite with at least one axial slot of the shell and, on the other hand, at least two lateral slots of the cap extending offset from at least two corresponding slots in the shell.
    According to a feature of the shutter, the upper face of the rods forms a hatch for closing the slots in the shell.
    At the same time, the ventilation circuit comprises at least two front suction openings on the shell and at least two corresponding ejection openings on the shell which extend offset towards the rear of the helmet.
    The invention makes it possible to modify and adjust the flow rate of the aeration and ventilation circuits by means of a single shutter integrated into the helmet.
    Thanks to the invention, the flow rates of aeration and ventilation streams are significantly higher, which makes it possible to obtain both better temperature regulation inside the helmet as well as more demisting. faster and more effective mask.

    DETAILED DESCRIPTION OF EMBODIMENTS Naturally, the embodiments illustrated by the figures presented above are given only by way of nonlimiting examples. It is explicitly provided that we can combine these different modes and variants to offer others.
    Figure 1 is an exploded perspective view of an embodiment of a helmet according to the invention for the practice of alpine skiing and used here with a mask M.
    This helmet is symmetrical with respect to a median longitudinal axis. However, it would be possible, without departing from the scope of the invention, to make the components of the helmet asymmetrically, such as, for example, the ventilation and ventilation circuits and orifices, if only for aesthetic reasons.
    This helmet includes a cap 1 whose concave inner profile substantially matches the skull and which, for reasons of comfort and safety, is made with a shock absorbing material (for example a foam material of the expanded polystyrene type PSE or expanded polypropylene PPE). The helmet can also include a comfort lining, generally made of flexible foam or textile, and positioned between the user's head and the cap.
    This helmet also includes a rigid outer shell 2 made of a material of greater hardness in order to form a shield against shocks. The material which forms the shell is a thermoplastic material such as PVC, ABS, or polycarbonate, obtained by injection. Optionally, the plastic material forming the shell can be loaded with fibers, for example glass, carbon or kevlar, or any other type of fiber, possibly natural.
    Furthermore, the helmet is traditionally provided with a set of adjustable links (not shown) ensuring its positioning and its maintenance on the head of the user.
    The helmet can be provided, on its front edge, with a visor B, as in the embodiment illustrated in FIG. 1.
    The inner shell 1 and the outer shell 2 are secured to one another (for example, by bonding, or any other technique for securing a shell with a shell) by delimiting between them, a on the one hand, a ventilation circuit A and, on the other hand, a ventilation circuit V.
    The ventilation circuit A is intended to improve comfort by ensuring the evacuation of the hot air trapped around the skull of the user.
    This ventilation circuit A comprises two sets of through slots.
    A first set of slots consists of at least one upper slot and, here, three upper slots 11a formed through the wall of the cap 1 and coming opposite with at least one upper slot and, here, three upper slots 21a formed through the outer shell 2, as illustrated in FIGS. 1 and 3.
    A second set of slots consists of at least two lower slots 11b arranged laterally and symmetrically on each side of the helmet, through the wall of the cap 1 and coming opposite with at least two corresponding lower slots 21b provided at through the outer shell 2, as illustrated in Figures 1 and 3.
    According to variants not shown of the invention, the air passages delimited by the slots in the present figures could have different and varied profiles, to take the form of recesses or orifices, for example, at rounded or parallelepiped contours.
    This ventilation circuit A further comprises, on the cap 1, an upper central cavity 12 into which open the upper slots 11a, and at least two lower lateral cavities 13 into which open the lower slots 11b.
    The functions of the cavities 12, 13 of the cap 1 and their cooperation with other components of the invention will be described in more detail below.
    The ventilation circuit V is, for its part, intended for demisting the mask M by ensuring the escape of the condensed water vapor and trapped in the mask M.
    Of course, the ventilation circuit V remains operational and effective if the user wears glasses, sunglasses, or a retractable visor possibly integrated into the helmet or mounted outside the shell.
    The ventilation circuit V is delimited between at least one suction mouth and, preferably as in the embodiment shown, two mouths 10 formed on the front edge or, more generally, on the front part of the inner cap. 1 (under the possible visor B) and at least one, and here two, corresponding ejection vents 20 formed on the outer shell 2 and extending in an offset fashion towards the rear of the helmet.
    Alternatively, the mouths 10 may be provided on a protective piece attached to the front edge of the cap, or possibly made in the outer shell itself.
    The ventilation circuit V further comprises at least two lateral channels 15 formed on the cap 1 between the suction outlets 10 and the lateral cavities of the ventilation circuit A with which they are capable of being connected and to communicate via a conduit 16 forming an airlock for the passage of air.
    The ejection vents 20 of the ventilation circuit V communicate with the channels 15 upstream of the duct 16.
    When applying the mask M, the suction vents 10 of the helmet are positioned in the immediate vicinity of the upper edge of the mask. This upper edge is, in general, lined with a porous foam (not shown) and, where appropriate, communication openings with the outside intended to dissipate the condensation in the mask and which then come to be placed opposite the helmet suction ports 10.
    Once all the components of the helmet are assembled, the lateral cavities 13 and the channels 15 are covered by the wall of the outer shell 2, as illustrated in FIG. 1.
    A variant not shown would consist in reversing this structure by providing the lateral cavities and the channels in the wall of the shell instead of that of the cap.
    If necessary, the shell 2 is provided with complementary orifices 22 facing the mouths 10 of the cap 1 on the lateral flanks of the visor B, when it exists, as illustrated in the variants of FIGS. 1 and 3.
    In general, the hot air present in the upper part of the helmet is driven outwards thanks to the laminar air flows generated by the speed which create, via the slots 21a, 21b, a vacuum in the circuit internal ventilation A of the helmet, as illustrated by the arrows in dotted lines shown in the drawings.
    Similarly, these laminar flows create, at the gills 20, a depression in the ventilation circuit V which allows the extraction of water vapor from the mask M via the vents 10 and the gills 20, as illustrated by the arrows in solid lines appearing on the drawings.
    To optimize this vacuum effect, the lower slots 21a, 21b and the vents 20 are oriented on the helmet in the longitudinal direction and have bevelled edges, as illustrated by the drawings.
    Thus, the respective air exhausts from the aeration circuit A and the ventilation circuit V are substantially perpendicular, as visible in the figure.
    1.
    [0071] In parallel, the channels 15 of circuit of ventilation V have a section narrowed of Upstream 1'aval, as illustrated through the figure 1, this which promotes
    the suction of the air and its acceleration in the channels 15, in order to optimize the rate of extraction of the mist from the mask M from the mouths 10.
    According to the invention, it is planned to couple the ventilation circuit V with the ventilation circuit A to increase the level of vacuum in the ventilation circuit V and optimize the fogging extraction rate.
    For this purpose, the helmet is provided with an adjustable shutter 3 allowing the user, both and reversibly, to modify and adjust the output flow of hot air from the aeration circuit. A, and therefore the temperature inside the helmet, and to modify and adjust the air flow in the ventilation circuit V to thus modify the demisting capacity.
    According to an advantageous characteristic, the adjustable shutter 3 allows the ventilation circuit A to be connected to the ventilation circuit V, thereby modifying the demisting capacity.
    As illustrated in Figures 1 and 4, the adjustable shutter 3 comprises, for this purpose, an axial tongue 31 provided with a longitudinal opening 30 and an operating pin 35 which projects through the shell outdoor 2.
    The opening 30 is likely to come, by translation of the tongue 31, opposite the upper slots 11a of the cap 1 and the upper slots 21a of the shell 2 to open the ventilation circuit A.
    The tongue 31 rests on a longitudinal flat 12a forming a slide formed on the edge of the central cavity 12, as illustrated in FIG. 2.
    The longitudinal ends of the flat 12a of the central cavity 12 form stops for the sliding of the tongue 31.
    Pins 31a of small dimensions which project from the axial tongue 31 engage in corresponding holes made around the central upper slot 11a, to wedge the tongue 31 in the middle position in the cavity 12.
    Alternatively, small spikes (not shown) could protrude around the central upper slot 11a and engage in corresponding holes made on the axial tongue 31 to wedge it in the middle position in the cavity 12 .
    In another variant not shown, the shutter would be supported by the shell in the wall of which would be made holes cooperating with the pins of the shutter.
    The tongue 31 is connected, on either side, to two flexible arms 32 each carrying a flap 33 forming a valve between the aeration circuit A and the ventilation circuit V.
    The two arms 32 are housed and integrated in a sliding manner in two circular grooves 14 for guiding, formed between the central cavity 12 and the lateral cavities 13 of the cap 1, as illustrated by FIGS. 5A, 5B.
    According to a variant not shown, the shutter 3 is devoid of an axial tongue. The lateral arms 32 actuating the flaps 33 would thus be connected to one another via a connecting and operating element or left independent by being each provided with their own operating element.
    In this variant, the ventilation circuit A does not have a central exhaust orifice and the exhaust of the hot air takes place only through the lower slots 11b, 21b and the side cavities 13.
    The lateral cavities 13 have, at their front periphery, a first flat 13a on which rests and slides a support tab for the flap 33.
    The flaps 33 are made transversely on rods 34 connected to the arms 32 and rotatably fixed in the side cavities 13 of the cap. To this end, the end 34a of each link 34 has a curved profile and carries a lug (not shown) forming a pivot which is rotatably engaged in the cap, in a corresponding orifice formed on a second flat 13b located at the periphery rear of the lateral cavity 13.
    The rods 34 have an upper face 34b which extends under the shell 2 by marrying its internal wall, and at a distance from the bottom of the lateral cavities 13.
    The flaps 33 extend, in turn, transversely to the outer wall of the cap 1 and to the inner wall of the shell 2 and therefore substantially perpendicular to the upper face 34b of the rods 34.
    In order to obtain optimum compactness and good cohesion between the inner shell 1 and the outer shell 2, the shutter 3 is integrated and wedged vertically between the shell 2 and the shell 1 during assembly of the helmet. It is thus expected that its general envelope conforms to the external profile of the cap without having any additional thickness, with the exception of the stud 35 for actuating the shutter 3.
    More specifically, the axial tongue 31 is housed entirely in the central cavity 12 and the flaps 33 are integrated in the two lateral cavities 13 of the cap
    1. The assembly of the cap carrying the shutter with the shell is thus facilitated.
    The two arms 32 ensuring the connection between the tongue 31 and the flaps 33 are symmetrical and have a curvilinear profile bent forward. They are produced here with a small thickness of material and therefore have an elastic deformation capacity.
    The shutter is preferably made by molding a single piece of plastic. This material can, for example, be a thermoplastic material such as a polyamide or a polyurethane. As a variant, the material of the shutter could be a plastic loaded with fibers, or possibly a metallic material.
    The axial tongue 31 is capable of sliding forward and backward in the central cavity 12 of the cap 1 between its two longitudinal ends
    The translation of the axial tongue causes the curvilinear sliding of the arms in the grooves 14 and the pivoting of the rods 34 and, consequently, that of the flaps in the lateral cavities.
    The movement of the tongue forward pushes the arms 32 into the grooves 14 and causes the two conduits to be closed by the flaps 33
    Conversely, the displacement of the tongue 31 towards the rear, causes the conduits 16 to open. Thus, the pivoting of the flaps 33 takes place between a position of isolation of the two circuits, respectively, of ventilation A and ventilation
    V, and a communication position between these circuits. However, the stroke of the central tongue 31 allows the shutter to be positioned in any intermediate open position.
    In the isolation position of circuits A, V (FIG. 5A), the two conduits 16 are closed by the flaps 33.
    In this position, the upper face 34b of the rods 34 which forms a hatch is positioned under the lower slots 21b of the shell 2 to close them and the hot air around the head of the user is then retained at inside the helmet. This position therefore corresponds to the total closure of the ventilation circuit A.
    The movement of the flaps 33 in the cavity 13
    is accompanied by a displacement tangential of the face superior 34b of rods 34. In a variant no represented, the face upper 34b rods 34 presents a orifice
    likely to come opposite the slots 21b of the shell 2 to allow limited escape of the hot air trapped in the upper part of the helmet and therefore a minimum opening of the ventilation circuit A.
    In the communication position between the two circuits (Figure 5B), the side channels 15 of the ventilation circuit V then open, via the ducts 16, into the side cavities 13 of the ventilation circuit A. The channels 15 communicate then with the outside both via the gills 20 and the slots 21b.
    The extreme communication position (Figure 5B) also corresponds to the maximum opening of the ventilation circuit A since the upper slots 11a, 21a and the lower slots 11b, 21b of the shell and the shell open to the outside. .
    However, it is possible to place the shutter 3 in any intermediate adjustment position where the tongue 31 is disposed between the longitudinal ends of the central cavity 12. In this intermediate position, the ventilation circuit V remains open but the upper slots 11a of the ventilation circuit A are then partially closed.
    According to a variant not shown, the ventilation circuits V and aeration A can be independent and isolated from each other, for example, by a transverse wall formed in the lateral cavity 13 or carried by the shutter 3. The air arriving from the ventilation circuit V can then escape through the slots 21b which would also be used for the exhaust of the ventilation circuit A.
    Alternatively, the helmet can be manufactured according to a process called "in-mold". This manufacturing process consists in molding the helmet by fusing the outer shell with the inner shell in the same mold. The shell is obtained by injection molding and the shell is overmolded inside the shell. The advantage of this method is to lighten the structure of the helmet while strengthening its shock absorption capacity.
    With this method, two embodiments are possible.
    In a first embodiment, the cap is manufactured in two parts to integrate the shutter: a first part of the cap, of thin thickness, is molded on the shell. Another part of the cap, produced in a second mold and carrying the shutter, can be added from inside the helmet. The shutter then moves between two layers of cap.
    In the second mode, the shell is manufactured in two parts: a first shell part is then molded and the shell is molded over or vice versa. The cap then carries the lateral cavities and the channels. The shutter is then brought back into the recess of the shell and the first shell part is completed by assembly with a second shell part molded separately.
