Previously, motorcycles were considered as a hobby or were utilized strictiy for work (couriers), and therefore there used to be way less motorcycles in use compared to the present situation. Today the number of people switching from using cars and public transport to riding motorcycles (and bicycles) is increasing constanily. The reason why single track vehicles are becoming more and more popular is that they provide comfortable and fast transport, which despite some unresolved problems such as the complete lack of storage space for accessories, is very appealing. Besides that, hobby and fashion also remain, which is also a major driving force behind the popularity of this means of transport. Manufacturers put a major emphasis on the design and aerodynamics cf their newer and newer fashionable motoreycle models, which leaves no room for including built-in storage space or a subsequently mounted storage compartment. This trend as well as the manufacturing industry includes as an organic component the crash helmet as a primary and compulsory protection device, but the above presented problem has not yet been solved in spite of ongoing product development. Many motorcycle users (e.g. those who use so-called custom, naked, sport and supersport design motorcycles) value fashion, appearance of the vehicle, as well as aerodynamics and driving characteristics over comfort, and thus do not equip their motorcycle with any box adapted for storage (top box) or storage bag (so- called soft bag). This can be observed primarily in the case of narrow-build sport and supersport motorbikes where for the above reasons the provision of storage space also poses technical problems (fastening the various storage devices to the motorcycle is cumbersome). It is these motorcycle types that are affected most by technological progress and the revolution of design. In addition to basic protective devices (particularly the helmet and gloves) riding a motorcycle does not require anything else, however, when the rider arrives at his/her destination (e.g. to a cinema, theatre, shopping mall, restaurant, beach, etc.) storing these devices (especially the helmet) presents a serious problem. 10 15 20 25 30 WO 2018/042213 PCT/HU2017/000019 -3. With a little cleverness some helmet types can be chained to the motorcycle. As it will be demonstrated below, a number of prior art solutions are based on this approach (DE 29805594, DE 20 2014 006 062, US 3,831,407, EP 1031500 A1). Lacking a better option, in some cases riders apply this solution. However, none of these DIY- (do-it-yourself) solutions resolves the issue of storing the (sometimes very costly) helmet, and thus in most cases riders have to take their helmets with themselves (in the lack of other solutions), which in addition to be extraordinarily uncomfortable also exposes the helmet to potential damage. The helmet and the visor typically sustain damage (indentation, scratches, and other damage) in these situations. Sooner or later this necessitates the replacement of the helmetivisor. Documents revealed in this field are presented below. None of the approaches disclosed in the documents have ever been put to production, serial production, have been made available commercially, or have become a part of general knowledge. From the aspect of end users these solutions might as weil have been non-existent as they have not been available at all to them. The objects of these documents could not achieve commercial success — probably due to their shortcomings and faults described here — despite there being a long-standing need for solving the above described problems. These technical solutions are known only from these documents, and are presented only to the limited extent made possible by the documents. Some motorcycle types possess a factory-mounted “helmet lock” mechanism (which is a tiny metal hook that can be operated by a built-in lock), which indicates the manufacturers urge to search for a solution to the problem. This mechanism is therefore a tiny metal hook mounted on the side of the motorcycle on which the helmet can be hanged by its chin strap, which does not provide a real solution at all and there is also no practical experience indicating otherwise. In FR 2489775 a helmet fastening device is disclosed. The device has lateral strap elements extending along both sides of the helmet, and an upper strap that runs along the upper part of the helmet and interconnects the lateral strap elements at the middle. The lateral strap elements are configured such that by placing the device on the helmet situated on the seat they come together at the location where the longitudinal sides of the seat meet the helmet. The lateral strap elements are 10 15 20 25 30 WO 2018/042213 PCT/HU2017/000019 -5- In FR 2376783 a helmet fastening device is disclosed that comprises two straps riveted to the surface supporting the helmet, with a spacer extending between the straps such that the straps are arranged about the rivet at a specific angle. In US 5,531,364 a helmet fastening device is disclosed that comprises two straps which can be hooked to the sides of the seat (disadvantageously this is a very type-specific solution), with two further straps being connectable to connection elements attached to the seat. The connection elements are permanently joined to the seat (by screw joints), ie. the solution requires the modification of the motorcycle and a special seat arrangement in order that the straps to be hooked under the seat can function correctly. In the document the operation of the device is illustrated for a helmet having an essentially hemispherical shape. If the device was applied for a contemporary, modem crash helmet, much longer straps would have to be applied. This solution therefore requires a modification involving boring and making screw joints; itis a rigid structure assembled from metal sheets, is fixedly attached to the motorcycle, and the connection elements must remain on the motorcycle even when the helmet fastening device is out of use (ie. the motorcycle is used for travel). In FR 2547263 a further helmet fastening device is disclosed, comprising a circular portion adapted to be pulled on a helmet, with straps leading from the circular portion to attachment points fixed to the sides of the seat, to which the helmet can be “tied” by the helmet fastening device. The downward-extending straps are connected to the circular lateral strap element at multiple places. This approach therefore has the drawback that a respective attachment point has to be provided on each side of the seat. After the straps have been engaged they have to be pulled tight applying a tightener mechanism, and thus this solution causes damage to the material and the outer shell of the seat, or in case it is adjusted sufficiently loose to not damage the seat the device can be removed easily. The mechanism may be removed from the helmet by a rotating movement; this reduces the safety of the device. In the documents there are disclosed a number of such helmet fastening device configurations which encompass the helmet like a net, mesh, or bag, and provide a storage option by being attached to multiple attachment points of the motorcycle. 10 15 20 25 30 WO 2018/042213 PCT/HU2017/000019 -6- Such an approach is disclosed in WO 2011/135143 Af wherein the helmet fastening device has a mesh-like configuration; the drawings of the document iliustrate that the device can be applied for fastening the helmet to the fuel tank, to the seat or even to another location. H such a meshike device is made of a material that is sufficiently strong to provide anti-theft protection the weight of the device is exceedingly large, and it also has a complicated structure. According to the document the mesh made up of vertical and horizontal thin wires is connected to thicker steel wires which have their ends attached fixedly to the motorcycle. This approach does not provide a sufficient level of protection either. A similar approach is disclosed in FR 2369145 wherein the helmet can be stored essentially in a bag made of a closely woven net. Such an approach is disclosed also in the German utility model description DE 20 2014 006 062 U1 wherein the device capable of storing the helmet has a bag-like configuration, with a plurality of straps running alongside one another. DE 298 05 594 U1 discloses a device with the help of which the helmet can be fastened to or hung on a portion of a motorcycle. According to this solution the straps are placed on the helmet relatively close to one another, with the straps converging at the bottom of the helmet where they are interconnected. A similarly complex helmet fastening device is disclosed in US 8,087,270 B1, the device has a circular strap arranged around the top portion of the helmet, with a plurality of pairs of straps (in the drawing, five pieces) extending downwards as far as the bottom portion of the helmet where the pairs of straps are interconnected. With the help of the interconnected pairs of straps the helmet storage device can e.g. be hanged on the handlebar of the motorcycle. The mesh-like basket system of the document is made applying thin steel cables and slidable weak interconnections and thus the construction does not provide a sufficient level of safety. The helmet is hanged with the open portion facing upwards also in this case, which is disadvantageous. A similar technical solution comprising rings and chains is disclosed in US 3,831,407. The structure according to the document is made of thin and weak material, and does not provide a sufficient level of safety because it can be 10 15 20 25 WO 2018/042213 PCT/HU2017/000019 -8- The problem detailed above (i.e. what to do with the accessories used during the ride, especially the helmet and the gloves, and the mask worn under the helmet after arriving at the destination) has been in existence for a long time, and the approaches disclosed in the above cited documents also illustrate the need for solving the problem. Therefore there is a need for such solutions with which the helmet/'crash helmet can be fastened to the motorcycle, i.e. which can be applied for locking the helmet to the motorcycle in a safe and practical manner. Nowadays this need is even greater than it used to be previously. The constantly changing and modernizing design of motorcycles also requires that such solutions are provided which conform to these carefully designed shapes and do not deteriorate the visual impression of the motorcycle when a helmet fastening device is applied; this latter requirement is not fulfilied in the case of many prior art solutions. ltis supported by the approaches disclosed in the above documents that there is a long-standing need for such a helmet fastening device that can be realized as a lightweight, low-material device that is preferably better protected against forcing to come off compared to the approaches disclosed in the prior art, and thereby provides improved safety for storing and locking the helmet on the motorcycle seat compared to the approaches disclosed in the documents. DESCRIPTION OF THE INVENTION The primary object of the invention is to provide a helmet fastening device which is free of disadvantages of prior art approaches to the greatest possible extent. A further object of the invention is to provide such a helmet fastening device that can be realized as a lightweight, low-material device that is preferably better protected against forcing to come off compared to conventional solutions disclosed in the prior art, and thereby provides improved safety for storing and locking the helmet on the motorcycle seat compared to the technical solutions disclosed in the prior art If possible. 10 15 20 25 30 WO 2018/042213 PCT/HU2017/000019 -0- The objects of the invention can be achieved by the helmet fastening device according to claim 1. Preferred embodiments of the invention are defined in the dependent claims. The fundamental difference between the invention and the above mentioned approaches is the application of a fixed-projection connection element or a system thereof that — contrary to the various fixed solutions — provides connection to and secure retaining of any commercially available crash helmet type in a non- integrated manner. In the invention a single-degree-of-freedom strap element (typically a chain, a multiple-row machine chain) is applied that is arranged in a uniquely configured system and is kept oriented by fixed-projection connection elements. These features cannot be derived from any of the approaches disclosed in the above documents. A long-standing need is filled by the helmet fastening device according to the invention, such a device had not been developed in a satisfying manner in spite of a large amount of development work and the money spent in the field. The documents consulted during a search spanning a period of more than 40 years (starting in 1973) provide a decisive proof for the existence and presence of this long-standing need to solve the problem. None of these experimental prior art devices has seen production, serial production, has been marketed commercially or had commercial success. These or an improved version of any of these devices has practicaliy been nonexistent ffom a commercial or user aspect. The perfectly firm (stable) positioning and secure attachment of the helmet fastening device according to the invention may be provided by placing the device on the helmet and passing the locking strap element underneath the seat (or the frame structure supporting the seat). The helmet fastening device (helmet fastening construction (arrangement, mechanism), helmet locking device) according to the invention brings a significant improvement over the above described approaches. The great advantage of the helmet fastening device according to the invention is its universal nature; neither of the above described approaches can be considered universal to this extent.

MODES FOR CARRYING OUT THE INVENTION The helmet fastening device according to the invention is adapted for fastening a heimet to a seat of a motorcycle. Fig. 1A is a schematic side view drawing ilustrating an exemplary motorcycle 50. Fig. 1B is a schematic drawing illustrating an embodiment of the invention on a motorcycle. In Figs. 1C-1E the embodiment of the invention shown in Fig. 1B is illustrated in a position on a motorcycle 50 and applied to a helmet 10. A front seat 52 and a rear seat 54 of a motorcycle 50 is shown in Fig. 1A. In Fig. 1C a helmet 10 is fastened to the front seat 52, in Fig. 1D a respective helmet 10 is fastened to both seats 52, 54, while in Fig. 1E a helmet 10 is fastened to the rear seat 54 applying the helmet fastening device of Fig. 1B. The helmet fastening device according to the invention comprises two lateral strap elements (in the embodiment illustrated in Figs. 1B-1E, lateral strap elements 2 comprising lateral strap element portions 2' and 2") being arrangeable (may be arranged, being enabled to arrange) along opposite lateral portions of the helmet and being interconnected at their ends. Therefore, arranging the device according to the invention on a helmet, the lateral strap elements run along the sides thereof. The part of the helmet which is used to put it on, i.e. the part where the cyclist can put his head in the helmet, is termed the bottom of the helmet. This portion abuts against the seat 52 or 54 of the motorcycle 50 when the helmet fastening device is in use (the parts surrounding the bottom portion are the lateral portions). In many cases — such as in the cases illustrated in Figs. 1B-1E — the lateral strap elements have a substantially curved configuration or are made up of straight segments. The substantially curved shape may also be formed of straight segments (thus a single-degree-of-freedom chain can be applied for these segments); the line of the strap element is broken at the locations of the connection elements preferably applied at the connection points. In all cases the 10 15 20 25 30 WO 2018/042213 PCT/HU2017/000019 -47- embodiments wherein a larger number of upper strap elements are applied (see by way of example the embodiments depicted in Figs. 54-56). The helmet is not a part of the invention. By the clause e.g. that “the lateral strap elements are arrangeable (can be arranged) along opposite lateral portions of the helmet” it is meant that the lateral straps are positioned and dimensioned in the helmet fastening device in such a manner that after placing the helmet fastening device on the helmet they can be slid downwards over the lateral portions of the helmets to essentially encompass the helmet. And, with appropriate dimensioning, the upper strap element is arranged along the upper part of the helmet such that the lateral strap elements and the upper strap element are all tight (see e.g. Figs. 104, 11A). The helmet fastening device according to the invention further comprises a locking strap element (in the embodiment of Figs. 1B-1E, a front locking strap element 6) being connected to at least one of the lateral strap elements and being adapted for releasable (disengageable, openable) fastening to the seat. By the locking strap element adapted for releasable fastening to the seat it is meant that (of all components of the motorcycle) the helmet is fastened to the seat by the helmet fastening device, and that it is kept in place on the seat by means cf the locking strap element. In the device according to the invention the locking strap element is preferably designed to fit into the gap underneath the seat of a motorcycle (see Figs. 1C-1E); i.e. the locking strap element 6 is passed underneath the portion of the motorcycle supporting the seat (the seat support structure). Such a fastening solution utilizing more than one locking strap element portion can also be conceived by which - making use of special properties (frame structure, other structural components) of the motorcycle — the helmet can be fastened or clamped (locked) to the seat of the motorcycle. In that case such a (specially configured) locking element has to be applied to the ends of the two locking strap elements by means of which they can be fastened to the motorcycle. In the embodiment of Figs. 1B-1E the locking strap element 6 is connected to the lateral strap elements 2 preferably at their interconnection. Accordingly, the locking strap element is preferably arranged also in other embodiments such that it is connected to the lateral strap elements at one of their interconnections, preferably 10 15 20 25 30 WO 2018/042213 PCT/HU2017/000019 -18- via a locking connection element to be described below. Furthermore, as ilustrated in Figs. 1B-1E, during use it is passed underneath the portion of the motorcycle that comprises the seat, and is releasable connected to the lateral strap elements 2 at their other interconnection, at the other side of the seat (preferably via such a locking connection element — to be disclosed below — to which the end of the locking strap element can be connected). Such a locking strap element adapted to be passed underneath the seat can of course also be conceived which consists of more than one, e.g. two pieces that can be connected to each other under the seat. In this case a locking means (locking mechanism) has to be applied only at the connection of the two locking strap elements, the locking means being adapted for connecting the strap elements together appropriately tightly underneath the seat. In this case the connection elements utilized at any other strap element connection point can also be applied at the connection of the locking strap element and the lateral strap element (i.e. it is not necessary to apply a specially configured locking connection element comprising a locking arrangement). The term “strap element” is used to refer to any element that is capable of providing a system of straps, a strap mesh or a strapping arrangement. The strap elements are preferably made of such a material (e.g. metal) that cannot be stretched. Of course, the strap elements are meant to be resistant against such stretching forces which can be produced under normal circumstances by, for example, a thief. Accordingly, the strap elements are implemented as or comprise a machine chain (primarily, a duplex machine chain), the chain to be presented below (see Figs. 6A-6C), or even a strap element made of a metal (steel) material, for example a wire rope. The strap element is therefore a single-degree-of-freedom strap element (see detailed below in retation to exemplary strap elements). The strap elements are arranged such that they can only be displaced in the direction of the centre of the helmet and in the opposite direction but not sideways with respect to that. The system of strap elements (the direction of strap elements, see Figs. 24-5G) is preferably defined by the connection elements described in detail herebelow.
