Description

[0001] HELMET SUPPORT DEVICE

[0002] * * *

[0003] TECHNICAL FIELD

[0004] The present invention relates to a support apparatus for a helmet, preferably a motorcycle helmet, in particular adapted to allow the helmet to be securely supported, and / or fixed, on a vehicle to which the apparatus is, for example, fixed in an easily removable manner.

[0005] In the following description, reference will be mainly made to a motorcycle helmet and a vehicle in the form of a motorcycle, this does not exclude that the helmet may be of a type designed for a different use and that the vehicle may be of another type or even that in place of the vehicle there is a piece of furniture or a portion of a building.

[0006] TECHNIQUE NOTE

[0007] As is known, protective helmets are worn on the user's head when necessary, and then put away when no longer in use, both to preserve their hygiene, at least of the internal portion that comes into contact with the user's head, and to prevent them from falling to the ground, with the risk of being damaged, or in any case of being scratched.

[0008] This need is particularly felt in the motorcycle field, since when, for example, a motorcyclist stops and takes off his helmet, the bulk of the object, and the lack of storage space on motorcycles, make said helmet essentially a burden.

[0009] Generally, for short breaks, the helmet is placed by the user on the saddle or on the tank, or even on a rear-view mirror, of the motorcycle. However, these support solutions are risky because a little wind, or sometimes the force of gravity itself when the surface on which the helmet is placed is inclined, as happens for example when the motorcycle is parked on its side stand, can be enough to make the helmet fall to the ground.

[0010] Another solution, generally used during longer breaks, consists in fixing the helmet to the motorcycle with a chain. This solution is also not optimal for various reasons. From a hygienic point of view, the situation is not perfect both because the chain comes into contact with the internal environment of the helmet, and also because the helmet can often be fixed in this way only if turned with the opening, through which it is worn, facing upwards. Furthermore, regarding the solidity of the fixing, for it to be optimal, the chain should embrace particularly tightly the helmet and the motorcycle, but this involves both a practical difficulty in connecting the two, and the risk of scratching both the helmet and the motorcycle.

[0011] So while on the one hand the helmet is prevented from falling to the ground (but not from rolling on the surfaces of the vehicle in cases where the chain is not particularly tight), hygiene and stability problems remain.

[0012] Another solution, for vehicles equipped with trunks or a sufficiently large under-seat compartment, is to place the helmet inside during parking. However, this implies a significant, if not total, reduction of the available cargo space on the vehicle.

[0013] SUMMARY OF THE INVENTION

[0014] An object of the present invention is to provide an apparatus capable of solving the problems of the prior art. In particular, an object of the invention is to provide an apparatus capable of stably supporting a helmet, which allows a reduced risk of contamination of the interior of the helmet, and which is at the same time compact and removable.

[0015] In particular, the invention provides a support apparatus configured to support a helmet, wherein said apparatus comprises:

[0016] - a base body, and

[0017] - a helmet support assembly, which support assembly is connected to said base body.

[0018] Thanks to this solution, a support device is made available that stably holds a helmet.

[0019] According to one aspect of the invention, the helmet support assembly may comprise, or may consist of, an extendable device having a fixed end integral with the base body and an opposite free end movable along an extension path relative to the fixed end, and wherein the extendable device is configured to be insertable inside the helmet and is configured to be operable between a retracted configuration, in which the free end is accommodated in an internal volume of the base body or is at a minimum distance from the base body, and an extended position, in which the free end protrudes externally from the base body or is at a maximum distance, greater than the minimum distance, from the base body.

[0020] Thanks to this solution, a compact support apparatus is made available that stably holds a helmet thanks to the extendable element.

[0021] Furthermore, in use, the helmet must be positioned on the free end of the extendable device, which contacts an internal portion of the helmet shell that rests on this free end. It follows that when the helmet is resting on the free end, the opening into which the user inserts his or her head to put on the helmet is facing downwards, thus reducing the possibility that dirt, for example carried by the wind, can enter the helmet and that, for example, raindrops can wet the inside of the helmet.

[0022] According to another aspect of the invention, the extendable device may comprise, or consist of, a telescopic tube or a pantograph.

[0023] In this way the extendable device is particularly compact and light. Furthermore, between the two options, the telescopic tube may be preferable because, unlike the pantograph, it does not have edges in which one can get caught and, in the case where there is an inflatable cushion, as will be introduced later, it allows to reduce the volume of the inflatable cushion, therefore the time needed to inflate it.

[0024] According to yet another aspect of the invention, the support assembly may comprise, in addition or as an alternative to the extendable device, preferably in addition to it in order to improve the stability of the positioning of the helmet on the base body, an inflatable device equipped with an inflatable cushion comprising a portion integral with the base body and which is configured to occupy at least partially the inside of the helmet.

[0025] In this way, the stability of the helmet on the support device, and the adaptability to helmets of different sizes, is improved, as the inflatable cushion expands and holds the helmet firmly, and furthermore its flexibility allows it to hold helmets of substantially any size and type and internal shape. Therefore, thanks to the inflatable cushion, the helmet is firmly held by the pressure exerted by the inflatable cushion on an internal surface of the helmet, or on an internal padding / internal shell of the helmet. Even when the extendable device is also present, the helmet is not simply supported on the free end of the extendable device, and possibly on a portion of the base body, but is firmly held by the pressure exerted by the inflatable cushion on an internal surface of the helmet, or on an internal padding / internal shell of the helmet. Furthermore, in the presence of the inflatable cushion it is not strictly necessary for the extendable element to be positioned substantially vertical, it could also be inclined as the pressure of the cushion ensures correct retention of the helmet even if it is positioned upside down.

[0026] In the case where the inflatable cushion is combined with the extendable device, one aspect of the invention provides that the inflatable cushion can be annular in shape and coaxial with the extendable device.

[0027] Furthermore, another aspect of the invention provides that when the inflatable cushion is inflated, i.e. while it is being inflated, it rests on the extendable device.

[0028] Regardless of whether or not the extendable device combined with the inflatable cushion is present, according to a further aspect of the invention, the apparatus may comprise a cushion inflation device, optionally housed in a receiving volume of the base body, configured to cause the cushion to assume an inflation condition that varies between a condition of maximum inflation and a condition of maximum deflation.

[0029] For example, the inflation device can be electro-mechanical.

[0030] According to one aspect of the invention, the support assembly may comprise or consist of one of the extendable device and the inflatable device, or may comprise or consist of a combination of them.

[0031] According to a further aspect of the invention, the base body may comprise a tubular lateral surface coaxial to an axis and whose cross-section in at least one section is reduced when going along said axis, for example in a direction away from the first portion of the fastening device when this is present.

[0032] This further improves the stability of the helmet, as the shape of the base is such that it is inserted partially and gradually into the helmet, which can then rest with its lower portion of the padding, for example that corresponding to the cheeks and / or the nape.

[0033] According to another aspect of the invention, the apparatus may comprise a stabilizing device fixed to the base body, which stabilizing device may comprise at least one of, or consist of, one of:

[0034] - a suction cup that rises from a portion of the base body,

[0035] - a weight of at least 1kg fixed externally to the base body or housed inside it,

[0036] - a perforated fixing flange which rises from a portion of the base body,

[0037] - a clamp connected to a portion of the base body, and

[0038] - a removable fastening device comprising a first portion and a second portion, wherein the second portion is integral with the base body and is configured to be connected to the first portion by means of a removable fastening mechanism.

[0039] According to one aspect of the invention, the second portion of the removable fastening device can be made in one piece with the base body, in particular with a (lower) portion of a boxshaped casing of the base body.

[0040] The invention also provides a self-propelled two-wheeled vehicle equipped with the support apparatus according to any of claims 1 to 9, wherein the base body is fixed directly to a component of said vehicle, or is integrated into a component of said vehicle.

[0041] The invention further provides a self-propelled two-wheeled vehicle equipped with the support apparatus according to claim 8, and wherein the first portion of the removable fixing device is directly fixed to a component of the vehicle, wherein optionally the vehicle is a motorcycle, wherein more optionally such component is a tank of the motorcycle.

[0057] DETAILED DESCRIPTION OF THE INVENTION

[0058] The present invention will now be described, for illustrative but not limitative purposes, according to its preferred embodiments, with particular reference to the attached figures.

[0059] In particular, in the figures, 1 indicates a support apparatus, which is configured to support a helmet H, in particular a motorcycle helmet.

[0060] Such helmets generally have an outer shell, usually made of polymeric or composite material, a visor hinged to such outer shell, an inner shell housed inside the outer shell and at least partially covered by an internal padding, at least one strap configured to fasten the helmet to a person's head. The outer shell may optionally include a chin guard; in this case the helmet is of the full-face type, like the one illustrated in the figures.

[0061] The support apparatus 1 comprises a base body, or base structure, 10, which is for example connectable to a vehicle V, or is configured to be coupled to an element of a vehicle V.

[0062] The base body 10 may comprise a rigid base frame 15, for example made of metal or polymeric material, and a protective casing, for example of tubular shape or box-shaped, which at least partially contains the base frame 15 inside it. It is not excluded that the base frame 15 and the protective casing may be a single element, for example co-molded or made of the same material.

[0063] The protective casing may comprise an annular or tubular side wall 25, for example extending from a perimeter edge of a bottom wall of the protective casing itself and / or from a perimeter edge of a bottom wall of the base frame 15.

[0064] The annular or tubular side wall 25 (hereinafter referred to for brevity as tubular side wall 25) can be provided with an annular or tubular external surface 30, for example which extends coaxially to a Z axis between a first end, for example proximal to the bottom wall of the protective casing and / or the base frame, and an opposite second end, for example distal to the bottom wall of the protective casing and / or the base frame.

[0065] The annular or tubular external surface 30 may be tapered, or may have a tapered trend, in particular along the Z-axis. In detail, the annular or tubular external surface 30 has a width, or diameter, that decreases, for example in a monotonous manner, going from the first end to the second end. In further detail, the width, or diameter, of the section profile of the external tubular surface, obtained by sectioning the external tubular surface itself with a section plane perpendicular to the Z-axis, decreases going from the first end to the second end.

[0066] For example, the annular or tubular external surface 30 (in the rest of the discussion for brevity it will be referred to only as the tubular external surface 30) comprises at least one section shaped like a portion of the lateral surface of a truncated cone. It is not excluded that the tubular external surface 30, in alternative embodiments not illustrated, could be pyramidal in shape (with rounded edges) or semi-oval or semi-spherical or even be composed of several types of complex and overall tapered surfaces.

[0067] The fact that the tubular external surface 30 is tapered allows the base body 10 to be partially inserted into helmets of different sizes (through an opening in the external shell into which the helmet user inserts his head), in order to support, albeit precariously, a helmet when it is placed on the base body 10.

[0068] The tubular side wall 25 may have an annular edge 35, for example circular, which defines an access opening to a volume inside the protective casing, in particular corresponding to the second end of the tubular external surface 30.

[0069] Alternatively or in addition to the tapered shape of the tubular outer surface 30, the wall 25 at the annular edge 35 may be rounded, or domed, and configured to fit partially inside a helmet in order to temporarily support it.

[0070] The protective casing can be made of metal or polymeric or composite material and is preferably also rigid like the base frame 15.

[0071] The base body, for example its protective casing and / or its base frame 15, can be fixed directly, for example in a non-removable manner (with "non-removable" we mean without the aid of suitable tools and without having to disassemble elements of the vehicle) to an element of a vehicle V or of a furnishing accessory or of a building. Or the base body, or its protective casing and / or its base frame 15, can be an integral part of a component of a vehicle V or of a furnishing accessory or of a building.

[0072] As an alternative to these two fixing methods, the support apparatus 1 may comprise a stabilizing device fixed to the base body, i.e. to its protective casing and / or its base frame 15, for example in the vicinity of the back wall and / or its first end, and by means of which the base body is configured to be made stable on a vehicle or a piece of furniture, such as a table, or a portion of a building, such as a wall.

[0073] As illustrated in Figures 13-16, the stabilizing device may comprise at least one of, or be made up of, one of:

[0074] - a suction cup 40, or a plurality of suction cups 40, which rises from a portion of the base body, for example which rises from an external wall of the bottom wall of the protective casing, in a direction away from the annular edge 35,

[0075] - a weight 45 of at least 1kg, for example between 2kg and 4kg, fixed externally to the base body or housed inside it,

[0076] - a perforated fixing flange 50 which extends from a portion of the base body, for example which extends from an external wall of the bottom wall of the protective casing, preferably in a direction away from the annular edge 35, and

[0077] - a clamp 55 connected to a portion of the base body, for example protruding from an external wall of the bottom wall of the protective casing, in a direction away from the annular edge 35. With reference to the other figures, the stabilizing device may also comprise, or be constituted by, a removable fastening device 60 comprising a first portion 65 and a second portion 110, wherein the second portion is integral with the base body 10 and is configured to be connected to the first portion 65 by means of a removable fastening mechanism.

[0078] The suction cup 40 and the weight 45 allow the support apparatus 1 to be made stable on a substantially horizontal surface, such as the top of a piece of furniture.

[0079] The perforated fixing flange 50 and the clamp 55 allow the support apparatus 1 to be made stable in various conditions, for example on a piece of furniture, such as a piece of furniture, or on a wall of a building, etc., for example in a non-removable manner.

[0080] The removable fastening device 60 allows the support apparatus to be made stable on a vehicle, in particular the first portion 65 is configured to be fixable, for example by means of threaded or snap-on connection members, to an element of the motorcycle V, in particular to a tank of the motorcycle V. In even more detail, the first portion 65 is configured to be fixable to a flange of a tank cap of the motorcycle V by means of threaded connection members. In the illustrated embodiment, the first portion 65 comprises a flange 75 equipped with through holes 80 configured to be passable by threaded connection members, for example in the form of screws. This flange 75 can be annular in shape, for example semicircular, or circular like the one illustrated in the figures.

[0081] The first portion 65 also comprises a section equipped with a central body 85, for example directly and rigidly connected, preferably without residual degrees of freedom, to the flange 75, and a first arm 90 and a second arm 95, for example having the same length starting from the central body, which develop starting from the central body 85 along a respective first development axis Bl as regards the first arm 90 and along a respective second development axis B2 as regards the second arm 95. The arms 90,95 are for example also mirrored with respect to each other with respect to a plane of symmetry equidistant from them and which intersects the central body in a central area thereof. In particular, said arms develop along the respective development axes Bl, B2 from opposite ends, for example longitudinal, of the central body and can also be directly and rigidly connected (without residual degrees of freedom) to the flange 75. At least one between the central body, the first arm 90 and the second arm 95 is directly and rigidly connected, preferably without residual degrees of freedom, to the flange 75.

[0082] The first arm 90 and the second arm 95 may be parallel to each other or preferably divergent from each other, for example with respect to said plane of symmetry, and as a whole they develop from the central body in a same removal direction from it. In other words, the central body 85, the first arm 90 and the second arm 95 as a whole form a body shaped like a wishbone, or U or C, in particular in which the reciprocal distance between the arms increases going from the central body to the respective free ends. In further detail, in the illustrated embodiment, the first arm, the second arm and the central body extend substantially along a path defined by the imaginary perimeter of a semi-ellipse, cut in proximity to the minor axis by a section plane parallel to the minor axis, or perpendicular to the major axis of the ellipse.

[0083] With particular reference to figures 6-11, the first arm 90 and the second arm 95 can be coplanar with each other, for example the first development axis Bl and the second development axis B2 can lie on a plane substantially perpendicular to the central axes of the through holes 80 of the flange 75.

[0084] The first arm 90 and the second arm 95 can be externally delimited in their extension by a respective external surface coaxial to the corresponding development axis B1,B2, for example substantially tubular, preferably also substantially planar, i.e. free from functional grooves or protuberances, in particular also substantially smooth.

[0085] Each arm 90, 95 can extend from the central body 85 to a respective free end 90a, 95a, which has for example a tapered shape with respect to the rest of the arm and in which the extension of the cross-section of the arm (transverse with respect to the respective axis of development) decreases gradually by advancing along the axis of development for at least a length equal to at least one third of the width of the section of the arm immediately upstream of the free end. In particular, the decrease in cross-section between two sections at a predetermined distance from each other in the free end can be greater, for example at least 20%, but not more than 60%, for example between 20% and 30%, compared to the decrease in crosssection between two sections at a predetermined distance from each other in the arm immediately upstream of the free end. In particular, the free end can be shaped like a semisphere or a semi-ellipsoid, or a semi-spheroid, or a cone, or a truncated cone, or a pyramidal prism, or a truncated pyramidal prism. In further detail, each free end 90a, 95a has a length in the direction of the development axis of the corresponding arm at least equal to one third of the maximum width of the cross-section of the arm immediately upstream of the free end. In even greater detail, each free end has a cross-section that gradually disappears and is coaxial to the respective development axis.

[0086] Each arm 90,95 can comprise a respective coupling section 100,105, the function of which will be explained below, which can be coaxial to the respective development axis B1,B2 and / or can develop starting from the free end and, as in the illustrated embodiment, can comprise the respective free end 90a, 95a.

[0087] Each arm 90, 95 can extend up to the respective free end 90a, 95a with a preferably tapered path at least in correspondence with the coupling section, for example along the entire extension of the arm going from the central body to the respective free end.

[0088] In detail, by tapered it is meant that the cross-section identified by the intersection with a section plane perpendicular to the respective development axis B1,B2 at the section point, decreases, for example in a monotonous manner, going from the central body to the respective free end, at least for the length of the coupling section 100,105, for example for the entire length of the arm up to the respective free end 90a, 95a.

[0089] It is specified that by "decreasing section" in reference to the arms, it can be understood that each arm, at least in the coupling section, can comprise a first portion of external surface and a second portion of external surface, which second portion is opposite to the first with respect to a plane on which the development axis of the respective arm lies, or which is tangent to the development axis of the respective arm in correspondence with an area of the arm where said first and second portion of external surface are identified, where said first and second portion of external surface are convergent with respect to each other going from the central body towards the respective free end 90a, 95a. Furthermore, more specifically in the embodiment illustrated, by "decreasing section" in reference to the arms it can also be understood that at least one of the length of the perimeter of the section, the extension of the width of the section and the extension of the height (to be understood as a dimension perpendicular to the width) of the perimeter of the section, or possibly all three dimensional aspects, varies, at least in correspondence with the coupling section 100,105, decreasing between two adjacent sections going from the central body to the respective free end.

[0090] In the illustrated embodiment, the entire perimeter of the cross sections can vary in length (the shape of the cross section remains substantially the same at least along the coupling section, for example along the entire arm with the possible exclusion of the rounded free end) decreasing, for example in a monotonous manner, going from the central body to the respective free end, at least in correspondence with the coupling section 100,105, for example along the entire arm.

[0091] Furthermore, in the illustrated embodiment, the cross-sections may have a perimeter of substantially the same shape, at least in the coupling section, for example along the entire arm (with the possible exclusion of the free end), and this perimeter may be for example of a rounded shape, in the sense that at least a quarter, for example at least half, preferably the entire perimeter comprises one or more curved lines.

[0092] In the illustrated embodiment the perimeter of the cross-section may be elliptical. However, it is not excluded that in alternative and less preferred embodiments not illustrated, the perimeter of the cross-section may be circular or semi-circular or semi-elliptical or polygonal with rounded edges.

[0093] In the illustrated embodiment, at least the coupling sections are radially delimited in a direction away from the respective development axis by a tubular lateral surface, which for example has the characteristics described above with regard to the shape and variation of the cross-section.

[0094] Regardless of the exact shape of the cross-section of the arms, the arms 90,95, and for example also the central body 85, have a flattened shape along a direction perpendicular to a plane of the development axes Bl and B2. In particular, the height of the arms, and for example also of the central body, perpendicular to said plane of the development axes Bl and B2 is less than the width of these elements identified by a section with the plane of the development axes Bl, B2. For example, said height may be less than 2 / 3 of the width, or preferably equal to or less than 1 / 2 of the width.

[0095] With reference to the illustrated embodiment in which the cross-section is elliptical, this ellipse is arranged with the minor axes perpendicular to a plane of the development axes Bl and B2.

[0096] In the illustrated embodiment, the arms 90,95 are not rectilinear, but curved, and the respective development axes are curvilinear, for example the first development axis Bl can develop along a section of a first quarter of an imaginary ellipse and the second development axis B2 can develop along a section of a second quarter of such imaginary ellipse mirrored to the first quarter with respect to a semi-axis, preferably major, of such ellipse. In particular, the central body and the arms 90,95 develop overall along the perimeter of a C or of a semi-ellipse cut along the minor axis or along a plane parallel to the minor axis and perpendicular to the major axis or along the major axis or along a plane parallel to the minor axis.

[0097] As a further detail, the cross-section of the central body is also of the same shape as the cross-sections of the arms, so for example elliptical. Depending on the roundness of the cross-sections, the first arm and the second arm, possibly also the central body, or their respective external surfaces, have an internal edge 106, which extends from the free end 95a to the free end 90a and which is interposed between the arms, which is rounded. Furthermore, this internal edge follows the path of the development axes, therefore, in the illustrated embodiment the edge extends along the perimeter of a semiellipse. Similarly, it also includes an external edge, opposite to the internal edge and which extends from one free end to the other and is also rounded in shape.

[0098] In the illustrated embodiment, the first portion 65 is constituted by the flange 75, the central body 85, the first arm 90 and the second arm 95.

[0099] The removable fastening device 60 also comprises a second portion 110 configured to act as a housing seat for at least part of the first portion 65 and to be fixable to the base body, or, as in the illustrated embodiment, which is part of the base body, in particular which is part of the bottom wall of the base body. Regardless of whether the second portion 110 is fixed to the base or is an integral part thereof, the second portion 110 may be located at the first end of the tubular external surface 30 and the second end of such surface 30 is therefore distal from the removable fastening device. In further detail, when the first portion is inserted into the second portion, the development axes of the arms 90,95 of the first portion lie on a plane substantially perpendicular to the Z-axis. Even more precisely, in the illustrated embodiment, the Z-axis is parallel to the central axes of the through holes 80 when the first portion is inserted into the second portion.

[0100] With particular reference to figures 11 and 12, the second portion 110 is equipped with a first housing seat 115 configured to accommodate, in particular with very little play, at least part of the first arm 90, or at least the coupling section 100, and a second housing seat 120 configured to accommodate, in particular with very little play, at least part of the second arm 95, or at least the coupling section 105.

[0101] The first housing seat 115 comprises a respective inlet opening 125 of the first arm 90, which is the first element of the housing seat to be passed through by the first arm, or by its free end 90a, during the insertion of the first arm into the first housing seat. Similarly, the second housing seat 115 comprises a respective inlet opening 130 of the second arm 95, which is the first element of the housing seat to be passed through by the second arm, or by its free end 95a, during the insertion of the second arm into the second housing seat. Such inlet openings 125,130 are for example made in the tubular external surface 30.

[0102] As stated above, the first arm 90 and the second arm 95 can be inserted, for example simultaneously, into the respective housing seats 115,120 (and extracted from them) by inserting them through the corresponding input openings 125,130, in particular by moving the first portion 65 with respect to the second portion 110 and / or the second portion 110 with respect to the first portion 65 and / or by moving them simultaneously in approach, for example only, along one, for example single, coupling direction A.

[0103] When inserting the arms into their respective housings, the first portion must be oriented by arranging the plane of the development axes Bl and B2 parallel to the coupling direction A.

[0104] The mating direction A is determined by the seating seats, for example, i.e. it is parallel to a central axis of each seating seat which passes through the inlet opening of the respective seating seat.

[0105] In particular, such central axis is the central axis of an internal surface of each housing seat, which internal surface is at least partially annular, and / or formed by multiple portions of annular surface, preferably tubular, and / or formed by multiple portions of tubular surface. Such annular or tubular surfaces or set of portions thereof, are substantially coaxial to said central axis. Such internal surface is a surface of the housing seat that can be contacted by the free end 90a, 95a and / or by the coupling portion 100,105 of the respective arm 90,95 while said respective arm is inserted inside the housing seat.

[0106] The housing seats 115,120 may be mirrored to each other with respect to a plane of symmetry parallel to the central axes of the housing seats and equidistant from them.

[0107] Each housing seat, i.e. its internal surface, has at least one section that can be contacted by the respective arm, in particular contactable at least by the coupling section of the respective arm and / or by the free end of the respective arm, which section of the housing seat for example has a tapered path going from the inlet opening 125,130 of the respective housing seat away from the inlet opening, along the coupling direction A.

[0108] In detail, by tapered it is meant that the cross-section of said contactable section, identified by the intersection with a section plane perpendicular to the respective central axis of the housing seat or perpendicular to the coupling direction A, decreases, for example in a monotonous manner, going from the inlet opening of the respective housing seat away from the inlet opening, along the coupling direction A.

[0109] It should be noted that by "decreasing section" in reference to the housing seats, it can be understood that each housing seat, at least in the section contactable by the arm, can comprise a first portion, for example of internal surface, and a second portion, for example of internal surface, which second portion is opposite to the first with respect to a plane on which the central axis of the respective housing seat lies, or on which the coupling direction A lies, where such opposing portions of the housing seat converge with respect to each other going from the inlet opening of the respective housing seat away from the inlet opening, along the coupling direction A. Furthermore, more specifically in the embodiment illustrated, by "decreasing section" in reference to the housing seats, it can also be understood that at least one of the length of the perimeter of the cross section, the extension of the width of the section and the extension of the height (to be understood as a dimension perpendicular to the width) of the perimeter of the cross section of the seat, or possibly all three aspects, varies, at least at the point contactable by the respective arm, decreasing between two adjacent cross-sections going from the inlet opening of the respective housing seat away from the inlet opening, along the coupling direction A.

[0110] Alternatively or in addition, this section of the housing seat that can be contacted by the respective arm, or this section with variable cross-section of the housing seat, can be defined as a section in which the passage section available to the respective arm decreases, going from the inlet opening 125,130 of the respective housing seat away from the inlet opening, along the coupling direction A.

[0111] In the illustrated embodiment, the entire housing seat, or almost the entire housing seat, has the tapered section described above. In other words, the portion contactable by the respective arm extends across the entire, or almost the entire, of the respective housing seat.

[0112] The variable section of each seat is, for example, step-free, preferably planar, i.e. substantially smooth, in the sense of free from protuberances or depressions of a nature that could hinder the sliding of the arm in its respective seat.

[0113] Similarly, for each arm, as previously stated, the coupling section of each of these arms has a variable section (and for example is free of steps, preferably the surface is substantially planar or smooth, free from protuberances or depressions of such a nature as to be able to hinder the sliding of the arm in its respective seat), with reference to the coupling direction A, the section of said coupling section of each arm, which decreases from a section which enters its respective housing seat last when the arm is inserted into said housing seat along the coupling direction A, to a section which enters the housing seat first when the arm is inserted into the housing seat along the coupling direction A.

[0114] In the illustrated embodiment, the cross-section of the coupling section of each arm decreases from the central body towards the free end, along the coupling direction A.

[0115] In the preferred embodiment illustrated, both the coupling section of the arms and the housing seat have a variable cross-section in order to obtain optimal centering, however this does not exclude the fact that the invention also includes devices in which the housing seat has a variable cross-section (as described above) and the arms have, at least in the coupling section, a constant or variable cross-section, but with a trend opposite to the decrease in section described above. Similarly, the invention also includes devices in which the housing seats have a constant or variable cross-section, but with a trend opposite to the decrease in section described above, and the arms have, at least in the coupling section, a variable cross-section (as described above).

[0116] In addition or as an alternative to the characteristics described above of each housing seat, the section of the housing seat that can be contacted by the respective arm, therefore the internal surface of the housing seat, in particular the section with variable section, may have a cross-section whose perimeter may be for example rounded, in the sense that at least a quarter, for example at least half, preferably the entire perimeter comprises one or more curved lines. In the illustrated embodiment, the perimeter of the cross-section may be elliptical. However, it is not excluded that in alternative embodiments not illustrated and less preferred, the perimeter of the cross-section may be circular or semi-circular or semi-elliptical or polygonal with rounded edges.

[0117] In the illustrated embodiment, the shape of the section of the housing seat at least in the section contactable by the arm has the same cross-section as the corresponding arm in the coupling section, so that the arm is inserted with very little play (i.e. a clearance with little play, ideally without play and without even interference) in said contacting part.

[0118] Furthermore, in the illustrated embodiment, the cross-sections of each housing seat may have a perimeter of substantially the same shape, at least in the section that can be contacted by the corresponding arm, for example along the entire seat.

[0119] Alternatively or in addition to the features described above, each housing seat can be shaped like a blind hole, for example it can be shaped like a blind hole complementary to the free end and to the coupling section of the arm insertable into it. However, it is not excluded that in alternative embodiments each housing seat can be a through hole that can be passed through from one side to the other by the respective arm.

[0120] With particular reference to figures 9-11, the second portion 110 may comprise, in addition to the housing seats, a groove 145 (of elongated shape, for example shaped like a channel) which extends between the first housing seat 115 and the second housing seat 120, for example it extends from the first to the second housing seat joining them. At least part of the central body 85 is inserted into the groove 145, in particular with very little play, for example also part of the arms 90,95 included between the central body and the respective coupling section.

[0121] The groove 145 may be made in the tubular outer surface 30.

[0122] The groove 145 is shaped to at least partially support the arms and / or the central body of the first portion, or to prevent movement of the arms and / or the central body of the first portion in a direction perpendicular to the coupling direction and / or to a plane of the development axes of the arms.

[0123] In addition, or as an alternative, to the coupling between the housing seats and the arms described above, the groove 145 has a variable cross-section (with respect to a section plane perpendicular to the coupling direction A) which decreases, going from an opening through which the central body enters the groove, in a direction away from said opening, along the coupling direction A.

[0124] The groove 145 may have a cross-section, cut with respect to section planes perpendicular to a longitudinal axis of the groove itself and / or parallel to the central axes of the housing seats, concave, for example U- or V-shaped, in particular shaped as a part, for example substantially half, of an ellipse.

[0125] The groove 145 in the illustrated embodiment may extend along the same curved path, for example in the shape of a half ellipse substantially as the arms and central body of the first portion. In particular, it may be the same semi-ellipse along which the internal edge of the first portion extends.

[0126] In further detail, at least one third, for example at least half, of the internal edge of the first portion, preferably the entire internal edge of the first portion included between the coupling section 100 and the coupling section 105, fits, in particular with very little play, into the groove 145. For example, the groove 145 can be defined by a concave surface (substantially like a channel) complementary to a portion of the first portion 65, or a portion of the arms and / or central body, in particular complementary to at least a portion of the internal edge of the first portion 65, preferably complementary to the entire internal edge of the first portion that extends between the coupling section of the first arm and the coupling section of the second arm.

[0127] Overall, the entire internal edge of the first portion 65 is inserted partly into the first and second housing seats and partly into the groove 145.

[0128] It is not excluded that in alternative embodiments not illustrated, the groove may be rectilinear or have another shape based on how the arms and the central body are shaped overall. In the case in which the groove is rectilinear, it cannot join the two housing seats.

[0129] The housing seats, the arms, the central body and the groove 145 can be shaped and sized so that the free ends of the arms, and for example at least a portion of the coupling sections, enter the openings of the respective housing seats before the arms and / or the central body enter the groove 145. In particular, the distance measured along the coupling direction A, between the openings of the housing seats and a point of the opening of the groove 145, into which the first portion is insertable, most distant from said housing seats and equidistant from said housing seats, is less than the minimum distance, measured along said coupling direction A, between the free ends of the arms and an internal edge point most distant from said free ends and equidistant from both free ends.

[0130] The second portion may be separated from the base body and may be shaped as a platelike body, or be equipped with a plate-like body, equipped with a first larger face facing the first portion, or on the flange of the first portion, an opposite second largerface, and a lateral surface, for example of annular shape, which connects said two faces. In this case, the openings of the housing seats and the groove 145 are made in said lateral surface of the plate-like body, in particular with the groove placed between said seats.

[0131] Regardless of the exact shape of the arm housing seats and the presence or absence of the groove, the removable fastening device 60 may comprise a removable fastening mechanism configured to connect the first portion 65 and the second portion 110 together in a rigid and removable, or resolvable, manner. In particular, this removable fastening mechanism selectively prevents and allows the arms to slide along the coupling direction A with respect to the housing seats and / or the groove 145 of the second portion 110.

[0132] The removable fastening mechanism may be provided with at least one locking seat, for example shaped like a hole or slot, made in the first portion 65, or in one of the first arm 90 and the second arm 95, or in the second portion 110, or in the first housing seat 115 or in the second housing seat 120 (in the sense that the hole or slot of the locking seat intersects the housing seat). The removable fastening mechanism is also provided with a locking element, for example a pin that can be inserted with very little play into the locking seat, or into the hole or slot of the locking seat. The locking element is movable with respect to the first portion 65 and the second portion 110 between a working position, in which it is inserted into the locking seat and connects the first portion 65 and the second portion 110 to each other, i.e. it blocks the arm that carries the locking element or the locking seat to the respective housing seat, and a rest position, in which it is external to the locking seat and allows the first portion 65 and the second portion 110 to move away from each other, i.e. it allows the arm that carries the locking element or the locking seat to disengage from the respective housing seat.

[0133] The locking element is movable along a sliding axis which may be transverse, for example perpendicular, to the coupling direction A and / or to the first development axis Bl or to the second development axis B2, depending on which of the two arms is affected by the movable element or the locking seat.

[0134] The removable fastening mechanism can also be substantially defined as a latch system, which therefore comprises a locking seat, i.e. a through or blind hole, into which a pin is selectively inserted which, when inserted into the seat, prevents movements of the body in which the hole is made and of the body with respect to which the pin is slidable in directions transverse to a sliding axis of the pin with such seat, for example creating a form connection.

[0135] In the illustrated embodiment, the locking seat is made, for example as a hole, in one of the two arms 90,95, in particular at or near the free end of that arm or in the coupling section of that arm, while the locking element, i.e. the pin, moves with respect to the second portion 110 along the respective sliding axis passing through a hole that intersects the housing seat of the corresponding arm equipped with the locking seat.

[0136] In further detail, with particular reference to figures 6, 7, 10-12 and, to ensure greater locking stability, in the illustrated embodiment, the removable fastening mechanism of the illustrated embodiment comprises a first locking seat 150, i.e. a first hole, made in the first arm 90, in particular at or near the free end of such arm or the coupling section of the first arm, a second locking seat 155, i.e. a second hole, made in the second arm 95, in particular at or near the free end of such arm or the coupling section of the second arm.

[0137] Accordingly, in the illustrated embodiment, the removable fastening mechanism comprises a first locking element 160, i.e. a first pin 160, slidably associated with the second portion 110 in correspondence with the first housing seat 115, or slidably inserted into a guide hole made in the second portion, for example in correspondence with the first housing seat 115, and having a central axis perpendicular to the coupling direction A and / or to the first development axis Bl, and a second locking element 165, i.e. a second pin 165, slidably associated with the second portion 110, for example in correspondence with the second housing seat 115, or slidably inserted into a guide hole made in the second portion, for example in correspondence with the second housing seat 115, and having a central axis perpendicular to the coupling direction A and / or to the second development axis B2.

[0138] Both the first locking element 160 and the second locking element 165 are movable, between the working and rest positions described above. In particular, in the rest position, these locking elements are entirely contained in the second portion 110 and do not protrude inside the respective housing seat, or in any case do not protrude in such a way as to interfere with the respective arm 90,95.

[0139] For example, when moving from the rest position to the working position, the first and second locking elements move away from each other.

[0140] The locking mechanism may comprise a device, for example in the form of one or more elastic elements 195, configured to exert on the locking element, i.e. on the first locking element 160 and on the second locking element 165, a force in the direction of maintaining the locking element in the working position. In this way, by inserting the arms of the first portion into the housing seats of the second portion, the locking element, i.e. the first locking element 160 and the second locking element 165, when it is aligned with the locking seat, i.e. when they are respectively aligned with the first locking seat and the second locking seat, is automatically inserted into said seat, or are automatically inserted into said seats, locking the second portion to the first portion 65.

[0141] The removable fastening mechanism may comprise a release actuator 180, such as an electric or electromechanical type, configured to actuate the locking element, i.e. the first locking element and the second locking element, at least from the working position to the rest position.

[0142] It is not excluded that in an alternative embodiment not illustrated, the release actuator may be manual. It is also not excluded that in an alternative embodiment not illustrated, the device that pushes the locking element into the working position may not be present and that the release actuator, whether manual or electrically actuated, is also configured to move the locking element, or locking elements, into the working position, as well as into the rest position.

[0143] Regardless of these considerations, the release actuator 180 may comprise a fixed body 185, for example rigidly connected to the second portion in the illustrated embodiment where the locking elements are slidably associated with the second portion, and a movable body 190, for example in the form of a stem, which moves relative to the fixed body along an actuation axis X (for example parallel to direction A) between a first portion, in which the locking element is in the working position, i.e. the first and second locking elements are in the working position, and a second position, in which the locking element is in the rest position, i.e. the first and second locking elements are in the working position. As mentioned above, in the preferred embodiment, the actuator is configured to selectively generate a force only to bring the movable body 190 into the second position only, and a push device, for example in the form of one or more spring elements 195, then brings (and maintains) the movable body 190 into the first position.

[0144] While it is not excluded that there may be a release actuator 180 for each locking element, in the illustrated embodiment there is only one release actuator 180 connected to the first locking element and the second locking element by means of a kinematic mechanism, i.e. a kinematic chain.

[0145] For example, the kinematic mechanism may include:

[0146] - a first guide body 200 (for example a body integral with the second portion 110 in which a through hole is made into which the first pin is inserted) of the first locking element, or of the first pin, to which said first locking element is slidably associated along the sliding axis of the first locking element itself,

[0147] - a second guide body 205 (for example a body integral with the second portion 110 in which a through hole is made into which the second pin is inserted) of the second locking element, or of the second pin, to which said second locking element is slidably associated along the sliding axis of the second locking element itself,

[0148] - a first rotating body 210 (for example a disk), which is rotatable with respect to the fixed body 185 around a first rotation axis, for example said first rotation axis lying on a plane perpendicular to the drive axis and being transverse (perpendicular) to the sliding axis of the first locking body; the first locking body, or its pin, is (at least) rotatably associated with the first rotating body at least with respect to a second rotation axis parallel to the first rotation axis (for example the first locking body comprises a protrusion transverse to the sliding axis of the first locking body itself, which is inserted into a rectilinear slot made in the first rotating body),

[0149] - a second rotating body 215 (for example a disk), which is rotatable with respect to the fixed body 185 around a third rotation axis, for example said third rotation axis lying on a plane perpendicular to the drive axis and being transverse (perpendicular) to the sliding axis of the second locking body; the second locking body, or its pin, is (at least) rotatably associated with the second rotating body with respect to at least a fourth rotation axis parallel to the third rotation axis (for example the second locking body comprises a protrusion transverse to the sliding axis of the second locking body itself, which is inserted into a rectilinear slot made in the second rotating body),

[0150] - a first connecting rod 220 that connects the moving body 190 of the actuator to the first rotating body 210,

[0151] - a second connecting rod 225 that connects the moving body 190 of the actuator to the second rotating body 215.

[0152] In this way, when the moving body moves along the drive axis, this sliding is transmitted to both rotating bodies by means of the first and second connecting rods, which rotating bodies, being dragged by said connecting rods, rotate with respect to the first rotation axis and the third rotation axis and dragging in this rotation the locking bodies which, by virtue of the guide covers, slide along the respective sliding axes.

[0153] The removable fastening mechanism may comprise a manual bypass assembly of the release actuator 180, which manual bypass assembly may comprise a push body configured to push the movable body of the actuator towards the second position, for example in opposition to the force exerted by the device which pushes towards the locking position the locking element or elements, or the one or more elastic elements in the illustrated embodiment.

[0154] This push body may comprise a cam 230 (or any other body eccentric with respect to a rotation axis), for example rotatable with respect to a cam axis perpendicular to a plane of the actuation axis of the release actuator, operated by means of a manual body that can be manipulated by a user.

[0155] In the illustrated embodiment, the manual body that can be manipulated by a user comprises a lock 235 connected for example to the second portion 110 (and accessible from the outside of the base body), which is connected by means of a shaft 240 to the cam 230. In particular, the shaft is connected to the lock and to the cam in a rigid manner, so that a rotation of a predetermined key inserted inside the lock causes a rotation of the shaft and therefore of the cam 230, which, following said rotation, pushes the mobile body of the release actuator towards its second position.

[0156] It cannot be excluded that in an alternative form of implementation not illustrated, both the movement to the working position and to the rest position may occur through the action of the electro-mechanical actuator.

[0157] Furthermore, it is not excluded that in an alternative embodiment not illustrated, both the movement of the movable body of the release actuator towards its first position and towards its second position may be controlled by the lock, in particular so that rotation of the lock in one direction leads to movement of the movable body in the first position, or leads directly (for example by means of kinematic mechanisms) to bringing the locking bodies into the working position, and that rotation of the lock in an opposite direction leads to movement of the movable body in the second position, or leads directly (for example by means of kinematic mechanisms) to bringing the locking bodies into the rest position.

[0158] The removable fastening device in the illustrated embodiment consists of the first portion 65, the second portion 110 and the removable fastening mechanism.

[0159] In order to power the release actuator, the removable fastening device may be equipped with an electrical power source, for example an electrical connection cable or an electrical power battery, for example at least partially housed in the second portion in the illustrated embodiment which provides for the release actuator to be on the second portion 110. In further detail, in the illustrated embodiment an electrical power battery is used, for example fixed, preferably without residual degrees of freedom, to said base body 10, or to the base frame 15 and / or to the protective casing.

[0160] Furthermore, the removable fastening device may comprise an electronic control and command unit, not shown in the figures, configured to operate the release actuator, in particular by selectively supplying it with electrical energy.

[0161] Such an electronic control and command unit may be connected to an on-site user interface unit, for example on the second portion and / or on the base body, preferably in the form of one or more buttons, or to a remote user interface unit, for example forming part of a remote control device, preferably a smartphone, wirelessly connectable to the electronic control and command unit. The user interface unit is configured to send predetermined control signals to the electronic control and command unit based on predetermined input received from the user, and the electronic control and command unit is configured to selectively send predetermined actuation commands to the release actuator based on the predetermined control signals received.

[0162] As previously stated, the second portion may allow the connection of an accessory, for example it may comprise arms and / or retaining mechanisms for retaining an accessory, or a seat or case for receiving the accessory. In the present case the accessory is what is fixed to the base body, therefore in the illustrated embodiment, the second portion 110 is for example connected, in particular rigidly, preferably without residual degrees of freedom, to the base body, or to its frame or protective casing.

[0163] The second portion 110 can be made of one piece with the base body, in particular with a portion (lower, of the second end) of the box casing.

[0164] Regardless of the presence or absence of the stabilizing device and its possible conformation, the support apparatus comprises a support assembly of a helmet connected, for example rigidly, preferably without residual degrees of freedom, to said base body 10, or to the base frame 15 and / or to the protective casing, in particular on a side opposite to the stabilizing device, or to the removable fastening device (to the second portion of the removable fastening device).

[0165] The helmet support assembly may comprise, or consist of, an extendable device 300 configured to fit at least partially inside the helmet, in particular configured to fit at least partially inside the helmet and to support it by contacting the internal padding of the helmet, for example by contacting at least a portion of the internal padding that usually contacts an upper portion of the wearer's head when the helmet is donned.

[0166] The extendable device 300 is equipped with a fixed end 305 integral with the base body 10, or with the base frame 15 and / or the protective casing, and an opposite free end 310, which is movable along an extension path with respect to the fixed end, and which for example comprises or constitutes a part of the extendable device configured to contact said internal padding of the helmet.

[0167] For example, also because it contacts the inside of the helmet, such free end 310 can be circular or discoid in shape, possibly rounded. For example, the free end 310 can comprise a discoid body, in particular also plate-shaped, with a possibly rounded perimeter edge. In an alternative embodiment, the discoid body can be equipped with a larger face facing in the opposite direction to the fixed end and which has a convex surface whose convexity faces in the opposite direction to the fixed end 305. Regardless of the exact shape, the free end 310, i.e. the discoid body, can be made of a material, or be coated with a material, suitable for contacting the inside of the helmet and for resisting atmospheric agents, for example it can be made of polymeric material or coated with polymeric material. It is not excluded that the polymeric material can be rigid or be a flexible rubber or resin in order to increase the friction.

[0168] The extension path along which the free end 310 moves may be along a rectilinear axis, for example transverse, i.e. perpendicular, to the bottom wall of the base body and / or to the coupling direction A and / or to a plane of the central axes of the housing seats 115,120. In the illustrated embodiment, the rectilinear axis of the extension path may be parallel to the Z-axis or may for example correspond to the Z-axis.

[0169] The free end 310, i.e. its discoidal body, may for example be arranged perpendicular to the extension path, e.g. to the Z-axis. In particular, the discoidal body may comprise a major face and an opposite second major face, which are perpendicular to the extension path, e.g. to the Z- axis.

[0170] It is not excluded that in alternative embodiments not illustrated the extension path could be a curvilinear axis, for example a section of a circumference or of an ellipse or of a parabola.

[0171] The extendable device is configured to be operable between, i.e. is configured to assume, a retracted configuration and an extended configuration. In the retracted configuration, the free end 310 may be accommodated in an internal volume of the base body 10, i.e. in an internal volume of the protective casing, or it may be at a minimum distance from the base body 10, i.e. it may be at a minimum distance from the second end of the side wall 25, or it may be at a minimum distance from a second end of the base body distal to the stabilizing device. In the extended configuration, the free end 310 may be at a maximum distance, greater than the minimum distance, from the base body 10, i.e. from the second end of the side wall 25, i.e. from a second end of the base body distal to the stabilizing device. Furthermore, in the extended position, the distance of the free end from the stabilizing device, i.e. from the removable fastening device, i.e. from the first portion 65 and / or from the second portion 110 of the removable fastening device, is maximum.

[0172] As an alternative or additional definition, in the retracted configuration the distance of the free end 310 from the removable fastening device, i.e. from the first portion 65 and / or from the second portion 110 of the removable fastening device, is minimal, and in the extended configuration the distance of the free end 310 from the removable fastening device, i.e. from the first portion 65 and / or from the second portion 110 of the removable fastening device, is maximal.

[0173] Furthermore, in the retracted configuration, the free end 310 may occlude, for example at least partially, preferably entirely, the opening 35 of the protective casing (substantially closing the box-like body).

[0174] In the extended configuration, the extendable device 300 may have an extension with respect to the base body, i.e. with respect to the second end of the base body or the lateral surface 25, as a result of which a helmet positioned on the free end 310 contacts the support apparatus at the free end 310 and at a portion of the base body, i.e. the tubular external surface 30 and / or at the edge of the opening 35. However, the extendable device is configured to have a maximum extension as a result of which the base does not support the weight of the helmet alone, but where such weight is at least distributed between both of these elements. Preferably, the extendable device may have an extension with respect to the base body, i.e. with respect to the second end of the base body or the lateral surface 25, as a result of which a helmet positioned on the free end 310 is spaced by a non-zero amount from the base body 10, i.e. does not contact it.

[0175] Regardless of whether or not the extension of the extendable device 300 may result in a contact of the helmet with the base body 10, the extendable device may be configured to allow adjustment of its maximum extension when in the extended configuration, i.e. to allow adjustment of its maximum extension. In particular, the extendable device may comprise a mechanism for adjusting the maximum extension of the extendable device, in detail configured to adjust the minimum distance of the free end 310 from the fixed end 305. This allows the extendable device to be adapted to various types and sizes of helmets without having to produce different extendable elements for each type of helmet. However, it is not excluded that in a less preferred embodiment, the fixed end 305 is connected to the base in a removable manner, for example by acting on threaded connection members and / or quick release mechanisms, and that a plurality of extendable devices of different sizes are present to adapt to different types of helmets.

[0176] In the illustrated embodiment, the free end 310, i.e. its discoid body, is connected by means of a threaded connecting member 320 screwed to an intermediate body of the extendable device connected to the fixed end, and movable with respect to said fixed end along the extension path, which threaded connecting member 320, for example a screw, is configured so that its rotation in the first direction determines a move of the free end 310, i.e. of the discoid body, towards the fixed end 305 and its rotation in a second direction opposite to the first determines a move of the free end 310, i.e. of the discoid body, away from the fixed end 305. In further detail, the free end 310, i.e. its discoid body, is slidably associated with the intermediate body along a sliding axis parallel or tangent to the extension path, and is for example rotatably associated in a free manner, and connected in sliding along said sliding axis, to the threaded connecting member 320, which for example protrudes from the free end towards the intermediate body into which it is screwed. Alternatively, the threaded connecting member could be integral with the free end 310, i.e. its discoid body, without any residual degrees of freedom and be screwed to the intermediate body. However, in this last construction possibility, a rotation of the threaded connecting member 320 also determines a rotation of the free end around the axis of the extension path.

[0177] The extendable device 300 may comprise, or consist of, a telescopic tube or telescopic rod, for example axially hollow and provided with a plurality of tubular sections slidably associated with each other, or a pantograph. In both cases the extension path is for example a rectilinear axis, i.e. the Z-axis.

[0178] In the illustrated embodiment, the extendable device comprises, or is constituted by, a telescopic tube, in particular with a substantially circular cross-section, although it is not excluded that in an alternative embodiment the cross-section could be polygonal.

[0179] The telescopic tube comprises at least two tubular sections slidably associated with each other (and partially inserted into each other) along the extension path and which respectively form the fixed portion and the free end. For example, the telescopic tube comprises at least three tubular sections slidably associated with each other (two by two partially inserted into each other) along the extension path and which respectively form the fixed portion, the free end and the intermediate body. In the illustrated embodiment, the tubular sections slidably associated with each other along the extension path are at least four (two by two partially inserted into each other), in particular they are six.

[0180] For example, each section may include a locking mechanism, not illustrated in the figures, configured to lock the relative sliding of two adjacent sections relative to each other, along the extension path, (only) in a relative position where the overall extension of the two adjacent sections along the extension path is maximum. Therefore, in the maximum extension configuration all sections of the telescopic tube are, relative to the adjacent one, with their respective locking mechanism locking said two adjacent sections in position. The locking mechanism includes a locking body, for example a notch, placed on a first tubular section, which is pushed by an elastic element against a surface of a second tubular section immediately adjacent to the first and in which a recess is formed in which, under the push of the elastic element, when the locking body is aligned therewith, said locking body enters therein, blocking the relative sliding between the first and second tubular sections. Similarly, the second tubular section will have a locking body to attach itself to a third tubular section. At least in the case where the telescopic tube has a circular cross-section, said telescopic tube may be equipped with an anti-rotation mechanism configured to prevent mutual rotation between the tubular sections of the telescopic tube itself around the axis of the extension path, in order to prevent the telescopic tube from rotating around said axis of the extension path and dragging the helmet with it. Such anti-rotation mechanism may comprise, in each tubular section, a protuberance and a recess that extend longitudinally parallel to the axis of the extension path, where each protuberance is inserted into the recess of an adjacent tubular section and directly slidably associated with it, forming with it a prismatic connection that allows only relative sliding between the two tubular sections in a direction parallel to the axis of the extension path. If the cross-section of the telescopic tube is polygonal, this measure can be omitted, since the crosssections already form a prismatic connection with each other which allows a relative sliding between the tubular sections in a direction parallel to the axis of the extension path.

[0181] It is not excluded that in an alternative embodiment not illustrated the extendable device could be operated between the retracted configuration and the extended configuration by an electrically operated actuator.

[0182] As an alternative to the extendable device, or in addition as in the case of the illustrated embodiment, the support assembly may comprise, or be constituted by, an inflatable device, for example comprising or constituted by an inflatable cushion 400 equipped with one, in particular a single one, portion which is connected, for example integral with no residual degrees of freedom, to the base body 10, in particular at the second end of such base body, or in a position opposite to the removable fixing device.

[0183] The cushion 400 is configured to at least partially occupy the inside of the helmet, for example only the inside of the helmet, preferably more than 60% of a volume of the inside of the helmet, when inflated, in order to support it, and partly retain it, by exerting pressure inside it, i.e. on the inside of the shell and therefore on the internal padding, in particular in a multiplicity of directions, for example of which at least two directions are substantially diametrically opposed to each other (for example with respect to the Z-axis).

[0184] It is not excluded that in an alternative embodiment not illustrated, the inflatable cushion 400 may be located inside a structure comprising several bodies movable, for example sliding, with respect to the base body 10 and which are selectively pushed by the inflation of the cushion

[0185] 400 against the inside of the helmet.

[0186] This cushion 400, when inflated, substantially rises from the base body 10, for example extending longitudinally along a transverse direction, i.e. perpendicular, to the bottom wall of the base body and / or to the coupling direction A and / or to a plane of the central axes of the housing seats 115,120. In the illustrated embodiment, the cushion 400 rises from the base body 10, to which it has for example a rigidly fixed portion with no residual degrees of freedom, extending longitudinally in a direction parallel, for example coaxial, to the Z axis.

[0187] Furthermore, when inflated, the cushion 400 may protrude radially, in a direction perpendicular to the longitudinal direction of extension, at least beyond the opening 35, for example beyond the base body 10, i.e. beyond its external tubular lateral surface 30.

[0188] In further detail, the cushion when inflated occupies a total volume at least double with respect to a volume occupied by the base body alone.

[0189] The cushion 400 can be configured to assume, when inflated, a shape of a convex solid, or mainly convex, preferably a shape of a convex solid obtained by the revolution of a geometric body around the longitudinal direction of extension of the cushion itself. By way of example and not limited to, the cushion when inflated can assume the shape of a drop, a spheroidal shape, an ellipsoid shape, or, even if less preferably, the shape of a ring or donut or toroid.

[0190] Regardless of its exact shape, the cushion 400 can be made of a polymeric material, and / or for example elastic, in particular elastic already at the pressures to which the cushion is inflated, for example pressures lower than 2 Bar, so that it can adapt to helmets of different types and sizes by extending during inflation. For example, the cushion 400 can be made partly or entirely of expanded PVC.

[0191] The inflatable cushion 400 can be lined with fabric, such as Lycra, to reduce wear on the helmet's internal padding and improve sliding during inflation and deflation.

[0192] When the inflatable cushion is not inflated, it is housed inside the base body 10, for example inside the protective casing.

[0193] In the illustrated embodiment, the inflatable cushion 400 is combined with the extendable device 300, in particular with the telescopic tube, and substantially surrounds it radially with respect to the axis of the extension path, i.e. the Z-axis. In particular, the inflatable cushion 400 may comprise a central tubular hole, for example cylindrical, coaxial to the longitudinal extension direction of the cushion itself, i.e. coaxial to the Z-axis, in which tubular hole the extendable device 300 is at least partially inserted. For example, the extendable device 300, in addition to being inserted into the tubular hole, protrudes externally from it with its free end 310, in particular with the discoid body of the free end, which in the illustrated embodiment is completely external to the inflatable cushion.

[0194] In this case, the inflatable cushion when inflated can take on an annular or toroidal shape and can rest on the extendable device 300, or on an external surface (formed by the external tubular surfaces of the tubular sections for example), preferably tubular, of the extendable device. In further detail, when inflated, the inflatable cushion 400 can take on the shape substantially of a sphere or an ellipsoid or a drop, which are axially crossed by said central tubular hole, for example cylindrical, coaxial to the longitudinal extension direction of the cushion itself, or coaxial to the Z axis, in which the extendable device 300 is inserted.

[0195] For example, the cushion 400 crossed by said tubular hole, can comprise an internal tubular wall 405, for example substantially cylindrical or truncated conical, which delimits said central tubular hole and which preferably has a circular cross-section and is coaxial to the longitudinal extension direction of the cushion itself, or coaxial to the Z axis.

[0196] The inner tubular wall 405 may have a first axial end 415, distal from the free end 310 at least when the extendable device is extended, and a second axial end 420 always proximal to the free end 310 when the extendable device is extended. The inner tubular wall 405 has an inlet opening at the first axial end 415, into which the extendable device 300 is inserted, and may comprise an outlet opening at the second axial end 420, for example from which the extendable device 300 can exit, in particular its free end 310. It is not excluded that the outlet opening may not be present and that the inner tubular wall 405 may form a blind hole, rather than a through hole.

[0197] The inflatable cushion may also comprise an external wall 410 configured to contact the inside of the helmet when the cushion is inflated (e.g., lined with fabric as described above) and having a circular cross-section and coaxial to the longitudinal extension direction of the cushion itself, or coaxial to the Z-axis when deflated and inside the base body. In the event that the tubular hole is not present, the tubular wall 405 is not present and there is only the external wall 410.

[0198] The external wall 410 is for example joined to the inner tubular wall 405 at the longitudinal ends 415 and 420, in particular at the openings at these longitudinal ends. In further detail, the external wall 410 extends from the inner tubular wall 405 starting from its inlet opening and from its outlet opening (if the latter is present as in the illustrated embodiment).

[0199] When the inflatable cushion 400 is inflated, the external wall 410 may take the shape of an outer surface portion of a spheroidal body, or an ellipsoidal body, or a teardrop body, or an annular or toroidal body.

[0200] The inflatable cushion 400 may comprise at least one portion (except for the fixed end) connected, for example without residual degrees of freedom, to the extendible device and movable with it along the extension path, as a result of which, when the extendible device is brought into the extended configuration, the inflatable cushion is extended, and for example at least partially extracted from inside the base body 10 in which it is housed, preferably entirely, when the extendible device is in the retracted configuration. In the illustrated embodiment, the inflatable cushion 400 is connected, for example directly and without residual degrees of freedom, to the extendible device 300 at the second axial end 420 of the internal tubular wall 405.

[0201] When the inflatable cushion 400 is connected to the extendable device 300, it can be operated in essentially three positions, a folded position (illustrated in figure 3), in which the inflatable cushion 400 is deflated and is at least partially, preferably entirely, housed inside the base body, i.e. the box-shaped casing, and the extendable device is in the retracted configuration, an extended position (not illustrated in the figures), in which the inflatable cushion is deflated, is extended and at least partially, preferably entirely, external to the base body as a result of the extension of the extendable device in the extended configuration, and a working configuration (illustrated in figures 4 and 5), in which the inflatable cushion is inflated, and at least partially, preferably entirely, external to the base body 10 as a result of the extendable device being in the extended configuration and / or of the inflation.

[0202] The inflatable cushion 400 may then comprise another portion, for example at the first longitudinal end 420, connected, for example without residual degrees of freedom, to the fixed end 305 and / or to the base body 10. This allows for improved distension of the cushion before inflation. In the illustrated embodiment, said other portion is connected to the fixed end 305 and / or to the base body 10 by means of a non-inflatable tubular body, for example of the same material as the extensible cushion. However, it is not excluded that it could be made of another material, and for example it could be formed by one or more ropes.

[0203] The portion of the inflatable cushion 400 movable together with the extendible device along the extension path can be connected, for example directly and / or rigidly, to the free end 310 and / or to the discoid body, or to the intermediate section or to a tubular section of the telescopic tube movable with respect to the fixed end 305. In the illustrated embodiment, said portion of the inflatable cushion 400 is connected, for example directly and / or rigidly, to the free end 310 and / or to the discoid body.

[0204] Alternatively or in addition to where the inflatable cushion 400 is fixed, in the illustrated embodiment, the inflatable cushion 400, in particular its internal tubular wall 405 can contact, for example by resting on, the extendable device, or an external surface (formed by the external tubular surfaces of the tubular sections for example), preferably tubular, of the extendable device. However, it does not exclude that in an alternative embodiment the internal tubular wall could be made of a material that can be bent by hand, but is sufficiently rigid at the pressures to which the cushion is inflated, for example lower than 2 bar, such that it does not deform under the pressure and does not contact the extendable device, so that an annular gap remains between the two. It is also not excluded that in an alternative embodiment, the extendable device, if such a substantially rigid wall is present, might not be present at all, or the telescopic tube might replace the internal tubular wall 405 and the external wall 410 would therefore be directly fixed to the telescopic tube.

[0205] It is not excluded that the cushion may have the central tubular hole even in the absence of the extendable device. In particular, in an embodiment not illustrated, the cushion may comprise within it a plurality of inextensible bridges, for example in nylon, which connect different points of the internal tubular wall 405 to corresponding points of the external wall 410, in this way the internal tubular wall, when the cushion is inflated, does not rest on the extendable device, since it is pulled radially outwards by said plurality of bridges. Therefore, in this case it would be possible to obtain a reduction in the inflation volume of the cushion without the need for the extendable device, on which the internal tubular wall 405 of the embodiment illustrated rests during inflation.

[0206] Although not illustrated, such inextensible bridges can be uniformly distributed circumferentially around the Z-axis, in order to uniformly pull the internal tubular surface.

[0207] It is not excluded that the cushion could have the central tubular hole even in the absence of the inextensible bridges. It is not excluded that the cushion could have the central tubular hole and the inextensible bridges also in presence of the extendable device 300.

[0208] Furthermore, it is not excluded that in alternative embodiments not illustrated there may be more inflatable cushions and / or that the inflatable cushion may be composed of more segments or more sectors, for example also inflatable separately, which, when compressed into a helmet, are able to lock it in position, since when they are inflated they exert pressure on its interior in various directions such as to retain the helmet. The inflatable cushion 400 is connected to an inflation device 440, i.e. an inflation and deflation device 440, of the cushion forming part of the apparatus itself and connected to the base body 10, for example housed in a receiving volume of the base body 10, i.e. of the protective casing.

[0209] The inflation device 440 is configured to make the inflatable cushion 400 assume a variable inflation condition between a condition of maximum inflation and a condition of maximum deflation, or equivalently one can say between an inflated condition and a deflated condition. In further detail, the inflation device 440 can be configured to regulate a pressure inside the inflatable cushion, or in its internal inflation volume, to make the cushion 400 assume a variable inflation condition between the condition of maximum inflation and the condition of maximum deflation. Such inflation device can for example use a gas for inflation, in particular ambient air in which the helmet support apparatus is located.

[0210] Such inflation device is for example external to the inflatable cushion 400, or to its internal inflation volume, and is for example connected to the cushion 400, or to its internal inflation volume, by means of one or more ducts (not illustrated in the figures). For example, the inflation device may be electro-mechanical, for example it may comprise a fluid operating machine, preferably a fan or a compressor (not illustrated in the figures), equipped with an electric motor and configured to at least push and / or compress said gas inside the cushion, or in its internal inflation volume. The inflation device may also comprise one or more valves (also not illustrated) configured to maintain in the cushion the pressure that the operating machine has established inside the cushion, even when said operating machine is not powered, or its motor is not powered.

[0211] It cannot be excluded that as an alternative to the operating machine, or in addition in parallel to it, there may be a manual air pump, for example a cushion or bulb pump or a piston pump.

[0212] In order to power the inflation device, the apparatus may comprise a source of electrical energy, for example an electrical connection cable (for example for connection to the battery of a vehicle on which the helmet support apparatus is installed) or an independent electrical power supply battery, for example fixed, preferably without residual degrees of freedom, to said base body 10, or to the base frame 15 and / or to the protective casing, in particular housed inside the base body 10, or the protective casing.

[0213] In the illustrated embodiment, the power supply battery of the inflator is the same as that of the removable fastening device.

[0214] Furthermore, the support apparatus may comprise an electronic control and command unit, not shown in the figures, configured to control the inflation device, i.e. to control the inflation and deflation of the cushion 400, for example autonomously and / or based on a control signal received from a user interface.

[0215] Said electronic control and command unit may be connected to an on-site user interface unit, for example housed on the base body and accessible from the outside, preferably in the form of one or more buttons, or to a remote user interface unit, for example forming part of a remote control device, preferably a smartphone, which can be connected wirelessly to the electronic control and command unit. The user interface unit may be configured to send predetermined control signals to the electronic control and command unit as a result of its operation by the user, for example by manipulating the user interface, and the electronic control and command unit may be configured to selectively operate the inflation device, i.e. the operating machine and / or the valve or valves connected thereto, based on the predetermined control signals received, for example by sending predetermined actuation signals to the operating machine, and / or the valve or valves connected thereto. As a result of the aforementioned actuation signals received, the inflation device, i.e. the operating machine and / or the aforementioned valves connected to it, selectively increase and decrease (or allow the decrease of) the inflation of the cushion.

[0216] In particular, upon receipt of a first predetermined command, forexample given by means of a first button on the user interface, the electronic control and command unit can be configured to send a first actuation signal to the inflation device, or to the operating machine and / or to the said valves connected to it, as a result of which the operating machine and / or the said valves are operated / switched and / or activated in such a way as to send a predetermined volume of gas into the cushion 400, or in such a way as to increase the pressure inside it by a predetermined pressure range.

[0217] Upon receipt of a second predetermined command, for example given by means of a second button on the user interface, the electronic control and command unit may be configured to send a second actuation signal to the operating machine and / or to the valve or valves connected to it, as a result of which the operating machine and / or said valves are actuated / switched and / or activated in such a way as to send a predetermined volume of gas from inside the cushion 400 to the external environment, or in such a way as to reduce the pressure inside it by a predetermined pressure range. Or, upon receipt of the second actuation signal, the operating machine and / or said valves are actuated / switched and / or activated in such a way as to allow a release of gas from inside the cushion to the external environment.

[0218] By way of example, one possible configuration of the inflation device could be an on-off valve placed, for example in a duct, between the operating machine and the cushion. In this case, to increase the inflation, i.e. to increase the pressure inside the cushion, the valve must be open and the operating machine must be electrically powered. To maintain the inflation level, i.e. the pressure, the operating machine must be turned off and the valve must be closed. To reduce the inflation level, i.e. the pressure in the cushion, the valve must be opened and the operating machine must be turned off. In this case, either the elasticity of the cushion and / or an external force must push out the gas inside the cushion. Alternatively, to reduce the inflation level, i.e. the pressure in the cushion, the valve must be open and the operating machine must be operated in the opposite direction to that in which inflation is obtained.

[0219] Regardless of the exact configuration of the inflation device, the inflation device may comprise an internal pressure sensor (not shown in the figures) configured to detect, for example directly, the pressure inside the cushion 400, in which case the electronic control and command unit may be configured to operate the operating machine and / orthe valves connected to it based on the control signals received from the user interface and based on an indicative value of the pressure inside the cushion 400 received from the internal pressure sensor.

[0220] For example, the electronic control and command unit may be configured, upon receipt of a predetermined command signal, for example a third predetermined command signal, to monitor the indicative value of the pressure inside the cushion and to operate the operating machine and / or the valve or valves connected to it, to send gas inside the cushion until the monitored indicative value of the internal pressure reaches and / or exceeds a predetermined indicative value of a maximum internal pressure, for example stored in a memory unit connected to the electronic control and command unit, or until the monitored indicative value of the internal pressure falls within a predetermined maximum pressure range, for example stored in a memory unit connected to the electronic control and command unit itself.

[0221] This configuration can be performed by the electronic control and command unit upon receipt of a predetermined control signal, for example the third predetermined control signal, optionally sent via a third button, or upon receipt of the first predetermined control signal, optionally sent via the first button. For example, it may be envisaged that upon receipt of the first predetermined control signal, for example sent by the first button, or of the third predetermined control signal, for example sent by the third button, the electronic control and command unit, when it detects via the internal pressure sensor that the detected indicative pressure value is below the predetermined indicative value of a maximum internal pressure or does not fall within the maximum pressure range, may be configured to subsequently activate the operating machine and / or the valve or valves connected to it, to send gas into the cushion until the monitored indicative internal pressure value reaches and / or exceeds the predetermined indicative value of a maximum internal pressure, or until the monitored indicative internal pressure value falls within the predetermined maximum pressure range.

[0222] The electronic control and command unit can be configured to, when it detects that the monitored indicative value of the internal pressure is equal to orgreaterthan the predetermined indicative value of a maximum internal pressure, or when it detects that the monitored indicative value of the internal pressure falls within the predetermined maximum pressure range, activate the operating machine and / or the valves connected to it in order to maintain the difference value reached, for example at least by preventing the escape of gas from inside the cushion, so that the operating machine does not have to be constantly switched on.

[0223] In particular, immediately after reachingthe aforementioned preset values, the electronic control and command unit can be configured to operate the operating machine, and / or the valves connected to it to block fluid communication between the inside of the cushion and the external environment. With the example circuit described above, it is sufficient to not power the operating machine and bring the valve to the closed position.

[0224] In addition, upon receipt of the first predetermined control signal sent by the first button, the electronic control and command unit, when it detects by means of the internal pressure sensor that the monitored indicative pressure value is equal to, or greater than, the predetermined indicative value of a maximum internal pressure, or the monitored indicative value of the internal pressure falls within the predetermined maximum pressure range, said electronic control and command unit may be configured to operate the operating machine and / or the valve or valves connected to it, to send a predetermined volume of gas into the cushion or to send gas into the cushion until the detected indicative pressure value is at least equal to the predetermined indicative value of a maximum internal pressure increased by a predetermined pressure increment value (e.g. stored in the memory unit) or until the detected indicative pressure value falls within a range of indicative values obtained by adding a predetermined increment value to the values of the predetermined maximum pressure range.

[0225] In addition, upon receipt of the second predetermined control signal sent by the first button, the electronic control and command unit, when it detects by means of the internal pressure sensor that the monitored indicative pressure value is equal to, or greater than, the predetermined indicative value of a maximum internal pressure, or the monitored indicative value of the internal pressure falls within the predetermined maximum pressure range, said electronic control and command unit may be configured to operate the operating machine and / or the valve or valves connected to it, to extract a predetermined volume of gas inside the cushion or to allow the gas to escape from inside the cushion until the detected indicative pressure value is at least equal to the predetermined indicative value of a maximum internal pressure decreased by a predetermined pressure decrease value (for example stored in the memory unit) or until the detected indicative pressure value falls within a range of indicative values obtained by subtracting a predetermined decrease value from the values of the predetermined maximum pressure range.

[0226] These two operating modes of the first and second buttons essentially aim to detail a more generic configuration according to which the electronic control and command unit, when configured to operate the operating machine and / or the valve or valves connected to it in a predetermined inflation configuration of the cushion until it automatically detects the achievement of a predetermined pressure level by means of the internal pressure sensor, can also be configured to allow a variation of the pressure inside the cushion, or its fine adjustment, based on commands that the user can send via the user interface, for example via the first button and the second button, which allow him to add or remove predetermined quantities of gas and to reach a desired pressure, or a range of desired pressures, independently of the predetermined indicative value of a maximum internal pressure and the predetermined maximum pressure range, stored in the default electronic control and command unit. Furthermore, the user interface and the electronic control and command unit can be configured to allow the user to modify the predetermined indicative value of a maximum internal pressure and / or the predetermined maximum pressure range, for example by means of signals sent via the first and second buttons, and to save this modified value.

[0227] This fine adjustment may not be completely free, that is, the electronic control and command unit may be configured to accept changes to the predetermined internal pressure values only if they fall within a safety range of pressure values, for example by sending an alarm signal if the user wants to select a pressure value higher or lower than the pressure values in the safety range.

[0228] Returning to the configurations based on the value of the parameter detected by the internal pressure sensor, the electronic control and command unit can be configured to, upon receipt of a predetermined command signal, for example a fourth command signal received from the user interface unit, monitor the indicative value of the pressure inside the cushion and to operate the operating machine and / or the valve or valves connected to it to expel gas from inside the cushion, or to allow the exit of gas from inside the cushion, until the monitored indicative value of the internal pressure reaches and / or falls below a predetermined indicative value of a minimum internal pressure, for example stored in the memory unit of the electronic control and command unit itself, or until the monitored indicative value of the internal pressure falls within a predetermined range of minimum pressure values.

[0229] This configuration can be performed by the electronic control and command unit upon receipt of a predetermined control signal, for example the fourth predetermined control signal, optionally sent by a fourth button, or upon receipt of the third control signal, optionally sent by the third button. For example, it may be envisaged that upon receipt of such a predetermined control signal, the electronic control and command unit, when it detects via the internal pressure sensor that the monitored indicative pressure value is at least equal to the predetermined indicative value of a maximum internal pressure or falls within the predetermined range of maximum pressure values, said electronic control and command unit may be configured to operate the operating machine and / or the inflation valve or valves connected to it to expel gas from inside the cushion, or to allow the exit of gas from inside the cushion for a predetermined volume, or until the monitored indicative internal pressure value reaches and / or falls below the predetermined indicative value of a minimum internal pressure or until the monitored indicative internal pressure value falls within the predetermined range of minimum pressure values.

[0230] In addition to the internal pressure sensor, the inflation device may comprise an external pressure sensor (not illustrated in the figures) configured to detect, for example directly, an indicative value of the pressure outside the cushion 400, in particularto detect an indicative value of the ambient pressure of the environment in which the helmet support apparatus is located. In this case, the electronic control and command unit may be configured to operate the operating machine, and / or the valve or valves connected to it, based on the control signals received from the user interface and based on a difference value between the indicative value of the pressure inside the cushion 400 received from the internal pressure sensor and the indicative value of the pressure outside the cushion 400 received from the external pressure sensor.

[0231] For example, the electronic control and command unit may be configured to monitor such a difference value and, upon receipt of a predetermined command signal, operate the operating machine, and / or the valve or valves connected to it, to send gas into the cushion until the monitored difference value (between the indicative value of the pressure inside the cushion 400 received from the internal pressure sensor and the indicative value of the pressure outside the cushion 400 received from the external pressure sensor) is less than a predetermined maximum difference value or until such monitored difference value does not fall within a predetermined range of maximum difference values. The predetermined maximum difference value and the range may be stored in the memory unit of the electronic control and command unit itself.

[0232] This configuration may be performed by the electronic control and command unit upon receipt of a fifth predetermined command signal, optionally sent by means of the third button or a fifth button, or upon receipt of the third predetermined command signal, optionally sent by means of the third button. For example, it may be provided that upon receipt of the predetermined command signal, for example the third predetermined command signal or the fifth predetermined command signal, the electronic control and command unit, when it detects by means of the internal and external pressure sensors that the monitored pressure difference value is below the predetermined maximum difference value and / or does not fall within the predetermined range of maximum difference values, may be configured to subsequently operate the operating machine, and / or the valves connected to it, to send gas into the cushion until the monitored indicative pressure difference value reaches the predetermined maximum difference value and / or until it does not fall within the predetermined range of maximum difference values.

[0233] Where the electronic control and command unit is configured to operate on the basis of the difference between the indicative values of the internal pressure and the external pressure, or at least on the basis of such difference, the control and command unit may also be configured to, when it detects that the monitored value of the difference between the indicative values of the pressure has reached the predetermined maximum difference value and / or is within the predetermined range of maximum difference values, operate the operating machine, and / or the valves connected to it in order to maintain the reached difference value, for example at least by preventing the escape of gas from inside the cushion, so that the operating machine does not have to be constantly switched on. In particular, immediately after reachingthe aforementioned preset values, the electronic control and command unit can be configured to operate the operating machine, and / or the valves connected to it to block fluid communication between the inside of the cushion and the external environment. With the circuit example described above, it is sufficient to not power the operating machine and bring the valve to the closed position.

[0234] After reaching the above preset values, and in the condition in which it has previously activated the operating machine, and / or the valves connected to it, to prevent communication between the cushion and the external environment, the electronic control and command unit can be configured to continue monitoring the difference in values between internal and external pressure and in the event that it detects a deviation from the predetermined maximum difference value and / or that the difference no longer falls within the predetermined range of maximum difference values, activate the operating machine, and / or the valves connected to it, to bring the difference back to the predetermined maximum difference value and / or within the predetermined range of maximum difference values.

[0235] In particular, in the event that the value of the monitored difference falls below the preset values, i.e. below the predetermined maximum difference value and / or below the predetermined range of maximum difference values, the electronic control and command unit activates the operating machine, and / or the valves connected to it, to introduce gas into the cushion, or to increase the pressure, until it detects that the monitored value of the difference of indicative pressure values has reached the predetermined maximum difference value and / or falls within the predetermined range of maximum difference values. In the event that the difference rises above the preset values, i.e. above the predetermined maximum difference value and / or above the predetermined range of maximum difference values, the electronic control and command unit activates the operating machine, and / or the valves connected to it, to extract gas from the cushion, and / or to allow the extraction of gas from the cushion, until it detects that the monitored value of the difference of indicative pressure values has reached the predetermined maximum difference value and / or is within the predetermined range of maximum difference values.

[0236] In this way, when the pressure varies, for example as a result of changes in altitude or temperature, the system is able to self-regulate in orderto guarantee the best grip of the cushion with the helmet.

[0237] In addition, upon receipt of the first predetermined control signal, optionally sent by the first button, the electronic control and command unit, when it simultaneously detects via the internal and external pressure sensors that the monitored pressure difference value is substantially equal to the predetermined maximum difference value and / or falls within the predetermined range of maximum difference values, can be configured to operate the operating machine and / or the valves connected to it to send a predetermined amount of gas into the cushion, in order to increase the pressure difference, in particular until the monitored difference value is at least equal to the predetermined maximum difference value increased by a predetermined pressure increment value (e.g. stored in the memory unit) or until the monitored difference value falls within a range of values obtained by adding a predetermined increment value to the values of the predetermined range of maximum difference values.

[0238] In addition, upon receipt of the second predetermined control signal, optionally sent by the second button, the electronic control and command unit, when it simultaneously detects via the internal and external pressure sensors that the monitored pressure difference value is substantially equal to the predetermined maximum difference value and / or falls within the predetermined range of maximum difference values, can be configured to operate the operating machine, and / or the valves connected to it, to expel a predetermined quantity of gas from inside the cushion, or to allow the escape of a predetermined quantity of gas from inside the cushion, in particular until the monitored difference value is at least equal to the predetermined difference value decreased by a predetermined pressure decrease value (e.g. stored in the memory unit) or until the monitored difference value does not fall within a range of values obtained by subtracting a predetermined decrease value from the values of the predetermined range of maximum difference values.

[0239] These two operating modes of the first and second buttons essentially aim to detail a more generic configuration according to which the electronic control and command unit, when configured to operate the operating machine and / or the valves based on the difference in the indicative pressure values detected by the internal pressure sensor and the external pressure sensor, can also be configured to allow a variation of the pressure difference inside the cushion, or its fine adjustment, based on commands that the user can send via the user interface, for example via the first button and the second button that allow him to add or remove predetermined quantities of pressure and to vary the pressure difference at will, by-passing the predetermined difference values. Furthermore, the user interface and the electronic control and command unit can be configured to modify the predetermined difference value and to save this modified value.

[0240] This fine adjustment may not be completely free, that is, the electronic control and command unit may be configured to accept changes to the predetermined internal pressure values only if they fall within a safety range of pressure values, for example by sending an alarm signal if the user wants to select a pressure value higher or lower than the pressure values in the safety range.

[0241] Returning to the configurations based on the value of the parameter detected by the internal pressure sensor and the external pressure sensor, the electronic control and command unit can be configured to monitor the indicative value of the pressure inside the cushion and to operate the operating machine and / or the valves connected to it to expel gas from inside the cushion, or to allow the exit of gas from inside the cushion, until the difference between the indicative values of the external pressure and the monitored internal pressure reaches and / or falls below a predetermined minimum difference value and / or does not fall within a predetermined range of minimum difference values, for example such values can be stored in the memory unit of the electronic control and command unit itself.

[0242] This configuration may be performed by the electronic control and command unit upon receipt of a sixth predetermined command signal, for example sent by a sixth button, or upon receipt of the third predetermined command signal, optionally sent by the third button. For example, it may be provided that upon receipt of a predetermined command signal, for example the sixth or third predetermined command signal, the electronic control and command unit, when it detects by means of the internal and external pressure sensors that the monitored pressure difference value is above the predetermined minimum difference value and / or does not fall within the predetermined range of minimum difference values, may be configured to subsequently operate the operating machine, and / or the valves connected to it, to expel gas from inside the cushion, or allow gas to escape from inside the cushion, until the monitored indicative pressure difference value reaches and / or falls below the predetermined minimum difference value and / or does not fall within the predetermined range of minimum difference values.

[0243] As an alternative to the pressure difference, for the deflation of the cushion, the electronic control and command unit could read the values of the internal sensor only, or even not read any sensor, and carry out the deflation methods described above upstream of the introduction of the internal pressure sensor and / or of the internal pressure sensor only. When the electronic control and command unit is configured to operate based on the difference between the indicative values of the internal pressure and the external pressure, or at least based on such difference, the control and command unit may also be configured to, when it detects that the monitored value of the difference between the indicative values of the pressure has dropped to at least the predetermined minimum difference value and / or is within the predetermined range of minimum difference values, operate the operating machine, and / or the valves connected to it in order to maintain the achieved difference value, for example at least by switching off the operating machine and / or by preventing fluid communication between the cushion and the external environment.

[0244] The ways in which fluid communication is prevented can be as illustrated above.

[0245] When it is written that the inflation device sends a predetermined volume of gas into or expels from the cushion, this configuration can also be obtained by operating the inflation device, i.e. operating machine and / or valves, for a predetermined interval of time.

[0246] In an embodiment not illustrated, the user interface installed on the base body has three buttons, including an on / off button, i.e. the third button described above, which allows the inflation device to be turned on, i.e. to inflate the cushion, and allows the inflation device to be turned off when it is turned on, i.e. when the cushion is inflated. In particular, turning on corresponds to the inflation of the cushion according to one of the modes described above (predetermined volume introduced, detection of the internal pressure sensor, detection of the internal pressure sensor and the external pressure sensor). Turning off corresponds to pressing the on / off button when the cushion has been previously inflated, as a result of which the inflation device performs the deflation of the cushion according to at least one of the modes described above (predetermined volume of gas released, detection of the internal pressure sensor, detection of the internal pressure sensor and the external pressure sensor). Among the three buttons on the user interface there is a pressure increase button and a pressure decrease button, which correspond respectively to the first button and the second button described above, that is, to the first control signal and the second control signal, when the third control signal is also present to carry out substantially complete inflation of the cushion.

[0247] Furthermore, the electronic control and command unit may be equipped with a wireless receiver device, preferably a wireless transceiver, configured to enable communication with a remote device, such as a smartphone, equipped with a user interface through which control signals can be sent via wireless communication to the electronic control and command unit. Control via remote device may be alternative or in addition to that of the user interface directly on the remote device, in the sense that the user interface on the base body may not be present and the electronic control and command unit would be controlled via the remote device.

[0248] In addition to the wireless connection, the electronic control and command unit could be connected to an electronic connector, for example a USB port, accessible for example from outside the base body and with which it is possible to establish a wired connection with the electronic control and command unit to control inflation and deflation independently of the wirelessly connected remote device and / or the user interface on the base body.

[0249] The user interface unit that controls the inflator may be the same as the removable attachment device.

[0250] The apparatus may comprise a movement sensor group, for example equipped with one or more accelerometers, housed in the base body and operationally connected to an electronic control and command unit, optionally the same one that controls the inflation and deflation of the cushion.

[0251] The electronic control and command unit can be configured to generate an alert signal, and possibly send it to a wirelessly connected remote device or to send it to an acoustic or luminous indicator on the device, when it simultaneously detects that the cushion 400 is inflated and that, by means of the motion sensor group, the support device is in motion.

[0252] For example, the detection of the fact that the cushion is inflated can be achieved by monitoring by the electronic control and command unit the indicative pressure value detected by the internal pressure sensor and / or external pressure sensor, or the electronic control and command unit can be configured to establish that after a command signal to inflate the cushion, a signal to deflate the cushion has not been received, and therefore the cushion is in the inflated condition.

[0253] Furthermore, detection of the fact that the support apparatus is in motion may be performed by the electronic control and command unit by monitoring the motion sensing assembly, and deducing that the support apparatus is in motion when a signal received from said sensing assembly exceeds a predetermined value for at least a predetermined time interval, or a predetermined pattern of changes in the monitored value is recorded, for example within a predetermined time interval. Although not illustrated in the figures, the support apparatus may be provided with a pair of grippable handles formed in the annular wall 25 or which extend externally from the annular wall 25. The operation of the support apparatus according to the invention illustrated in the figures is as follows.

[0254] When the removable fastening device 60 is present, starting from a condition in which the first portion 65 is fixed to an object, for example to a vehicle, in particular to a motorcycle as in the figures, the user, holding the base body 10 and / or the second portion 110, inserts the free ends 90a, 95a of the arms 90, 95 into the housing seats 115 and 120, which guide, possibly also thanks to the groove 145, said arms under the thrust of the user, until the first hole 150 and the second hole 155 are aligned respectively with the first pin 160 and the second pin 165, which, under the force exerted by the elastic element or by the elastic elements that insist on them, are automatically inserted into the holes 150 and 155.

[0255] At this point, the base body is integral with the vehicle and the user can extend the extendable device 300, bringing it to the extended configuration and also stretching with it the inflatable cushion 400 which is in the minimum inflation configuration, i.e. deflated, and then fit the helmet over it, resting the inside of the helmet on the free end 310 of the extendable device.

[0256] Once the helmet is positioned on the extendable device, the user can control the inflation device, for example by pressing specific buttons, for example the button or the third button, on the base body 10, or by sending an inflation command via the remote device, for example a smartphone on which an application for controlling the inflation device is installed. When inflating, the inflatable cushion 400 presses on the inside of the helmet, locking it in position, so as to prevent rotations or inclinations due to accidental impacts or atmospheric events.

[0257] When the helmet is held by the inflatable cushion 400, the electronic control and command unit, based on the pressure measured by the internal sensor and the pressure measured by the external sensor, operates the inflation device by inflating and / or deflating the cushion if the difference between the internal pressure and the external pressure varies with respect to the predetermined value or range of difference values. For example, the predetermined maximum difference value corresponds to a pressure difference that may be between 0.3 bar and 0.8 bar, preferably between 0.4 bar and 0.65 bar. Similarly, the predetermined range of maximum difference values may correspond to pressure ranges between 0.3 bar and 0.8 bar, preferably between 0.4 bar and 0.65 bar, or between 0.42 bar and 0.6 bar.

[0258] When the user needs to pick up the helmet, if he has previously inflated the inflatable cushion, he must now proceed with its deflation, for example by pressing specific buttons, for example the first button or the third button, on the base body 10, or by sending a deflation command via the remote device. When the cushion 400 is sufficiently deflated and does not press forcefully on the inside of the helmet, the user can remove the helmet.

[0259] The user can then return the extendable device to the retracted configuration and at the same time, the inflatable cushion, being connected to the extendable device, retracts into the base body, in a folded configuration.

[0260] If the user wishes to release the second portion 110 from the first portion, he can do so either by pressing a button on the base body (which can optionally be pressed after sending an unlocking security code to the electronic control and command unit), or by sending a command signal via the remote device, as a result of which the release actuator 180 moves the pins 160 and 165 to the rest position, thus allowing the extraction of the arms 90,95 from their respective housing seats.

[0261] In the event that the release actuator 180 does not work, for example because the device's power supply battery is flat, the user can switch to the manual by-pass group by inserting the key into the appropriate lock and turning it. By turning the lock, the push body rotates and pushes the actuator's mobile body towards the second position.

[0262] In this description, reference has often been made to a vehicle, which may for example be a vehicle without a passenger compartment, preferably two-wheeled, even more preferably self-propelled, equipped with a tank. For example, a motorcycle is illustrated in the attached figures and the support apparatus 1 is fixed to a tank of such a motorcycle, in particular by means of the removable fixing device 60. For example, the first portion 65 of the removable fixing device may be fixed, preferably by means of threaded connecting members, to the tank of the motorcycle. However, it is not excluded that in alternative embodiments the base body, or its protective casing and / or its base frame 15, may be made integral, or in a single body, with an element of the vehicle, for example with the tank of the vehicle, in particular with a protective casing of said tank.

[0263] It should be noted that in this discussion, "monolithic" means a body obtained from the solidification of a single casting or extrusion or moulding and from the eventual processing of such solidification only by removal of material.

[0264] It should be noted that in this discussion, when an element is defined as "rigid", it is understood that it is not significantly deformable under the normal workloads to which it is subjected. In particular, unlike an element defined as "elastic", a rigid body does not perform its function primarily on the basis of its own deformation.

[0265] In the foregoing, the preferred embodiments have been described and some variations of the present innovation have been suggested, but it is to be understood that those skilled in the art may make modifications and changes without thereby departing from the relevant scope of protection, as defined by the attached claims.
