Definitions

  • the invention relates to a helmet fastening device adapted for fastening a helmet (e.g. a crash helmet) to the seat of a motorcycle.
  • a helmet e.g. a crash helmet
  • 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.
  • a helmet fastening device 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 therefore interconnected at the sides of the seat, and such a construction starts from their interconnection points which can be introduced into and fastened to a respective lock mechanism fastened to both sides of the motorcycle.
  • This device has the great disadvantage that it necessitates the modification of the motorcycle (by mounting to it an additional structural component).
  • Modern crash helmets which, instead of the essentially hemispherical shape shown in the figures of the document essentially have the shape of an egg lying on its side.
  • the configuration of the device is not suitable because the single upper strap can be forced to come off sideways towards the sides of the seat such that it becomes possible to remove the helmet from under the straps, so protection against theft is not provided.
  • the "boxes" adapted for receiving the straps of the helmet fastening device are fixedly mounted on the motorcycle, and thus they are constantly disturbing. There is not always enough room on a motorcycle for this approach, and a suitable universal attachment point cannot always be found, and therefore it can be assumed that this solution can only be applied for certain motorbike types.
  • 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.
  • a helmet fastening device comprising 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), i.e. 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.
  • the operation of the device is illustrated for a helmet having an essentially hemispherical shape. If the device was applied for a contemporary, modern crash helmet, much longer straps would have to be applied.
  • a further helmet fastening device 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.
  • 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.
  • 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 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.

  • the helmet fastening device comprises two lateral strap elements (in the embodiment illustrated in Figs. 1 B-1 E, 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).
  • the helmet fastening device may be sufficient to manufacture in only a few different sizes (typically 1-2 sizes, by way of example for children and for adults as there are no major size differences within each category).
  • the strap elements may thus have a looser fit on smaller-sized helmets, however - as it is detailed in this document - protection against forcing to come off is preserved (the locking strap element can be locked sufficiently tight).
  • 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 via a locking connection element to be described below. Furthermore, as illustrated 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.
  • 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.
  • 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).
  • connection element 5 connecting to each other strap elements having connection ends
  • the fixed-projection connection element has projections (protrusions) in a number corresponding to the number of the strap elements connected by means of connection ends, and the projections are in a fixed arrangement in relation to each other, and fastening tabs being opposite each other are formed on the projection, and the connection end is connected to the fastening tabs by means of a fastening rod element (bar element; such as a rivet element, rivet (pin), bolt pin, or other fastening rod element may be passed therethrough) extending (passed) through the fastening tabs and the connection end.
  • the connection end is preferably arranged between the oppositely positioned fastening tabs, or such that it encompasses the fastening tabs.
  • the rod element applied as a fastening rod element is typically longer than the rod element (chain rod element) adapted for interconnecting the chain links. It can be seen that the lateral deflection of single-degree-of-freedom chains can be minimized by selecting appropriate tolerances.
  • the axis of the fastening rod element is perpendicular, to a good approximation, to the surface of the corresponding fastening tab. This allows that the connection end connected thereto can be rotated with respect to the fastening tab (i.e. that the fastening tab does not block its rotation).
  • the connection elements typically have dimensions in the range of a few centimetres, e.g. the width of the upper connection element (the distance between the end points of its oppositely positioned projections) is approximately 6 cm.
  • the fixed-projection connection element can simply be termed a "connection element” or e.g. "first connection element” but for the sake of differentiation the adjective "fixed-projection” has been included in the name.
  • the adjective "fixed- projection” is taken to refer to a configuration wherein the projections cannot be rotated relative to one another, i.e. that they are fixed with respect to one another.
  • the strap element can be connected to the projections by means of a connection end.
  • the connection end can be preferably rotated about the fastening rod element adapted for connecting the connection end and the projection.
  • the connection element can also be termed a strap element connection.
  • connection element 5 is illustrated only schematically; the exemplary realization of the projections of an applicable connection element, the connection ends of the strap elements, the fastening tabs and the provision of connections thereto can be observed in further figures (Figs. 7A, 12A, 19), showing some embodiments of the connection elements.
  • the (locking, lateral, and upper) strap elements are implemented as the chains of Figs. 22-23.
  • the locking strap element 6 is connected to a connection element to which the rear ends of the lateral strap elements 2 are also connected.
  • An additional upper strap element portion is arranged on the rear portion of the helmet (not visible in Figs. B- E) according to the strap element arrangement of Figs. 2A-2D.
  • the above characterized fixed-projection connection element is arranged (but, as shown in Fig. 1 B, not at the interconnection of the lateral strap element portions forming the lateral strap elements).
  • the strap elements terminating at the fixed-projection connection element are oriented with the help of (via) the connection element (and, when a single-degree-of-freedom strap element is applied, they cannot deviate from this direction) connected to each other.
  • connection point There are essentially three types of connection point in the helmet fastening device according to the invention: - the points where the lateral strap elements (of both sides) are interconnected - preferably the locking strap element is also connected at this point (front and rear connection elements; group 1);
  • connection points of the lateral strap elements and the one or more upper strap elements (lateral connection elements; group 2);
  • connection points of strap element portions of the upper strap element (upper connection element; group 3).
  • connection solution between the strap elements may be applied for any group independently of one another, i.e. the helmet fastening device may comprise the fixed-projection connection element presented in this description in any of the groups.
  • the helmet fastening device may comprise the fixed-projection connection element presented in this description in any of the groups.
  • the locations of strap element connection points where fixed-projection connection elements are applied are explicitly determined, with rotatable- projection connection elements being applied at some other connection points.
  • Fixed-projection connection elements can also be applied in group 2 (e.g. in the embodiments shown in Figs. 4A-4E or in Figs. 5A-5G); in which case the connection element typically has three branches (unlike the connection element shown in Fig. 17).
  • a rotatable-projection connection element is arranged in group 2.
  • Fixed-projection connection elements can also be applied in group 3 (e.g. in the connection devices according to Figs. 7A-7B and Fig. 18), for that it is typically required that a connection element with an X, Y or + shape is applied.
  • the strap elements may simply be passed above one another.
  • connection element is always applied at at least one of the connection points of the helmet fastening device according to the invention.
  • connection ends can for example be connected to the fastening tabs by a rivet element similar to those applied in machine chains (rivet elements longer than the rivet elements of machine chains may be applied as fastening rod elements, but other similar rivet elements or rod elements can also be applied).
  • the connection end for example the chain link/chain links functioning as a connection end, can be arranged between, or encompassing, the fastening tabs of the projections of the connection element.
  • the strap element 2 comprises strap element portions 2' and 2" that are connected to each other by means of a rotatable-projection connection element 9.
  • a locking connection element 7 is arranged at the interconnection point of the lateral strap elements 2 of both sides.
  • the locking strap element 7 has a configuration analogous to the connection element 5 (both are of fixed-projection type), i.e. the lateral connection straps 2 are connected to the fastening tabs of the corresponding projections of the locking connection element 7 by respective connection ends.
  • a portion of the locking connection element 7 adapted for connecting the locking strap element 6 is configured differently than these projections so as the locking strap element 6 can be releasable (and lockably) connected thereto (see also Figs. 13A, 13B).
  • a helmet can preferably be fastened to the seat applying the helmet fastening device according to the invention if the helmet is placed on the front or on the rear seating position.
  • the helmet fastening device can of course be applied for any other type of seat (motorcycle seat), such those wherein a single (optionally elongated) seating position is provided.
  • the essential features are that the helmet can be placed on the seat, and the locking strap element can be passed through the gap between the frame portion supporting the seat and the rear wheel, or can otherwise be fastened to the seat portion.
  • the helmet fastening device For dimensioning the helmet fastening device according to the invention it is of course preferred to take into account the future arrangement of the helmet since the lateral and upper straps should expediently be arranged over the helmet in a tight and taut manner when the helmet is locked.
  • the helmet fastening device according to the invention is targeted at using the most basic free spatial region of the vehicle. After a travel the seat is freed up and the softly cushioned seat that has so far been left completely unused offers itself for storing the helmet.
  • the helmet is preferably placed on the seat crosswise with respect to the direction of travel, with the open portion facing downwards, this position corresponding perfectly to the currently applied design of both the seat and the helmet, and since the seat and the helmet have essentially complementary shape the helmet lies in a perfectly stable position.
  • the locking strap element portion 16' and the strap element portion 16" are connected to the lateral strap elements 12 and to the upper strap elements 14 respectively at the interconnection of the lateral strap element portions 12' and the upper strap element portion 14" and at the interconnection of the lateral strap element portions 12" and the upper strap element portion 14"'.
  • the configuration of the lateral straps (including in this case also the upper strap element) and their included angles makes the device to be universally applied for a wide range of helmet sizes and shapes.

  • Non-straight strap elements necessarily consist of multiple strap element portions. Strap elements having an essentially arched shape can also be implemented utilizing a plurality of strap element portions, see the embodiments according to Figs. 5A-5G.
  • connection elements and other components are illustrated that can also be utilized in the embodiment illustrated also in Figs. 1 B-1 E.
  • the helmet fastening device illustrated in Figs. 1 B-1 E has four upper strap element portions that are connected to each other at the top part of the helmet.
  • a fixed-projection connection element 80 illustrated in Figs. 7A and 7B can be preferably arranged at this connection point, which has four projections 85 accordingly.

  • the Y- shaped arrangement on the side is highly preferable.
  • the diameter can vary within a very wide range determined by the length of the upper strap elements.
  • the upper and lateral strap elements always have an optimal fit on the helmet surface. This does not pose a problem because the locking strap element can be connected to the locking connection element at an arbitrary location, thus adjusting the locking strap element to an optimal length and providing an optimal position for the device on the helmet.
  • the locking auxiliary element 151 comprises locking pawls 147 (the manner of connecting the locking strap element to these pawls is illustrated in Fig. 13B), and an opening through which the locking auxiliary element 151 can be connected to the connection element 140 (i.e. into opening 146 thereof).

  • connection element 170 can be arranged in an embodiment of the helmet fastening device in a pair formed with the connection element 150 shown in Figs. 13A-13B; preferably a single instance of both elements is required; because a releasable connection can be made to the locking strap element applying the connection element 50, the connection of the connection element 170 and the locking strap element can remain fixed.
  • the connection element 170 has three fixed and one rotatable projections.
  • the strap element adapted for locking the device according to the invention should preferably conform to the position of the seat with respect to the seat frame structure that has to be embraced to an optimal extent by the locking strap element. If the seat position is not parallel with the frame structure supporting the seat, then in specific cases the locking strap element of the device according to the invention either cannot be aligned perpendicularly to the seat or such an alignment would result in a lateral tightening thereof.
  • the frame structure adapted for supporting the seat also comprises (carries) other components that have to be avoided in order to provide perfect alignment and support.
