The present invention relates to a device to be associated with respect to the deposits of the French patent applications filed by the present inventor under the following numbers and names: FR0706526 named "Reaction-hydrodynamic" kerbing device "and its respective PCT application (PCT / FR2008) (FR0801798) "Hydrodynamic kerbing device" and its respective PCT application (PCT / FR2009 / 000380) (marked (2)) and relates to all inventions of the same related inventive principle The present invention relates specifically to the related and / or similar type parts of the aforementioned devices which are alternatively called plastic stops, abutments, (or else longerons or fins if any), all of them requiring reference to their corresponding descriptions of their land tenure and represented opportunities; The possibilities and modalities described in these cited patent applications are to be considered as before and / or may relate to the present invention. Plastic abutments, abutments, (or longerons or fins if any) of related and / or similar descriptions within the cited patent applications, if they have in part potentially the capacity described in the present invention, directly or indirectly , do not have the presentation described here and the consequent desired effect. With respect to the inventions mentioned above (1) or (2) the device according to the invention has the aforementioned elements plastic stops (one or more), abutments (one or more), or longerons or fins (one or more), placing and / or related to the rest of the corresponding devices and in particular to the body of their walls (one or more) so as to be "mobile - dynamic" and even from their characteristics to fully describe this effect result.

In relation to the above-mentioned inventions, these plastic abutments (one or more), abutments (one or more), (or longerons or fins (one or more)) 2945956 -2-

may in particular be "composites" in general, and made of any possible materials and / or several materials associated and / or different mechanical qualities and / or complementary and thus constitute a set of nature more or less plastic and reactive or rigid; they may therefore be formed for example by flexible and deformable plastic structures under the influence of the applied water flows, in association with rigid bodies or more or less rigid and therefore less deformable; they may have sizes and shapes that may vary significantly, and be in any possible orientation that will have been initially given relatively and / or they will take and from any location. These can be attached to several distinct points of the wall assembly (one or more) to which they are attached and this in particular, on both sides of it. They react in concert with the aquatic flows that come to apply to it, and this from the mechanical physical effort generated by the user of the device, and are therefore, and are shaped to treat these streams of water, flows water 20 that they are printed and to which they confront or "rub" so to speak to reorient them relatively to the back of the direction in which one is heading; They can be presented in all forms and useful architectures; for example to be presented as relatively longiform bodies in particular, can therefore be rigid, of greater or lesser rigidity and / or more or less mechanical flexibility in particular, and this being either attached or placed on the wall assembly (one or more) to which they are attached, determine a greater or lesser mobility and / or mechanical and / or structural reactivity relative to the movement that is imparted to the device. They may in terms of external approximation of the wall assembly (one or more) to which they are attached being contiguous or more or less contiguous and / or partly detached from it (externally therefore, these precisions do not 35 concerning this time not and / or not directly the way they can, either be attached to the whole wall (one or more) or be placed there). 2945956 -3-

These may, and especially according to whether they are placed and / or are attached in greater or lesser extent to the whole wall (one or more) and / or according to their qualities in terms of materiality and / or their shapes present and be described for example 5 and in particular as "palmettes" or else, another relatively "opposite" example, and always as potentially they are placed and / or are attached in more or less part to all wall (one or more) and / or according to their quality in term of materiality and / or form 10 always be qualified and present themselves as "foils" and consequently like all structures or architectures related to it (eg fins , fins, fins, blades, etc ...) and any type of dynamic profiles possible; Several different types can be associated within the same device. These can therefore be positioned and / or fixed in any location deemed useful of the wall assembly (one or more) to which they are attached, including attack edges (and be from a zone or a point located or to from or from several distinct areas or points), and in particular, and generically in the relatively median portion of the "height" thereof; they (potentially) can also be positioned and / or genetically fixed both on either side of the wall, or on both sides at the same time. They have a sufficiently "confronting" surface and / or "catch" profile so that the assembly involved in actuating the device makes them capable of a desired and efficient reaction. These plastic abutments (one or more), abutments (one or more), (or longerons or fins (one or more)) can take or adopt any useful orientations or judged as such and this individually or collectively, and therefore varying orientations in relation to the given or general orientation of the rest of the device; They may each in particular, all together or several sets move in a particular direction, directly or indirectly, likewise and consequently, adopt an angle of attachment and / or of positioning not perpendicular to the average plane of 2945956 -4-

the wall assembly (one or more) to which they are attached; the latter can accommodate in its "height" on several levels or "floors" a variable number of them overlapping completely or in part. They can be in their structures even in conformations such as provided with shapes, cutouts and "deployments of matter" internal and / or external various; and thus to present themselves in their structures and their thickness in conformations of "voluminal" type, ie occupying a noticeable space in the three possible dimensions of space thanks to material extensions (or "deployments" ) varied and potentially consistent, unfolding on different levels and / or in different directions, these (one or more) may for example be with "split" and / or 15 "split" architectures, but still depending on deployments and / or material protuberances that may consequently potentially make it possible to form in themselves their own channeling and / or protection space with respect to shocks and / or damaging eddies that may come from outside (concretely they may in particular form they themselves a qualified structure of "battleship", or "in shell" or "in shell", and which thus forms a hydrodynamic fairing and / or nalisant vis-à-vis the flow of water, and which is thus placed according to the whole wall (one or more) to which they are attached, as appendix 25 dynamic monitoring of the flows thereof; Several of this type "volume" forming deployment structures and / or material protuberances and forming in themselves their own channeling and / or protection space will potentially, in more or less large parts of their structures meet the case 30 appropriate and if necessary). Conformations of shapes and internal and external cutouts such as showing including including various borders, notched architectures ("split" for example), "valvaires", etc .. is for example possible. These plastic stops (one or more), stops (one or more), (or rails or fins (one or more)) can be "adjustable" in terms of orientation on the wall assembly (one or more) to which 2945956 -5-

they are connected and who receives them; this capability may be made possible by one or more fastening systems such as using, for example, screws associated therewith and / or the wall assembly (one or more) to which they are attached; This ability to be adjustable can determine that these same plastic abutments (one or more), abutments (one or more), (or struts or fins (one or more)) can now be potentially removable from the wall assembly (one or more) to which they are attached and in general with all parts, "sub-parts" and components of the devices mentioned (in whole or in part only) and to be able to mutually fix or subtract each one from the other potentially thanks to one or more points of attachment 15 materialized by one or more suitable fastening systems, such as allowed by one or more screws for example or "velcro" systems, "clip" etc., including and for example and so that they can be easily interchanged; These plastic abutments (one or more), abutments 20 (one or more), (or longerons or fins (one or more)) can be attached to the footwear part (whether for one foot or two ( double)) and in particular at its front part, this in order to usefully limit in size and length the entire device using a useful space. Concretely the device comprises any elements (at least one), plastic abutments, abutments, (or else designated as spars or fins if appropriate), being placed and / or attached to the rest of the device and in particular to the body. one or more walls or structures - walls or walls forming so as to be "mobile - dynamic" and thus associating any element or system (one or more) able to allow any modality of mechanical mobility and / or facilitation thereof and, associating or joining any dynamically dynamic or dynamic bouncing system (it is not meant in this sense, systems acting as mere dampers and / or systems producing "static" bounces only, but systems designed to accompany a 2945956 -6-

movement in whole or in a significant way) possible by boosting mobility (one or more); the elements (one or more), plastic abutments, abutments, (spars or fins if appropriate) being placed and / or attached in this way, alone or together, on and / or through (and this thanks to cavities or openings) of one or more walls. In particular and for example, these elements (one or more) plastic abutments, abutments, (or designated as IO as longitudinal members or fins if appropriate) will be alone or together, provided with: - articulation systems (one or several) which may be in the form of axes also called articulatory axes (one or more), presenting in one or more rooms and potentially associating potentially with one or more other different articulation systems ( also to be understood here as axes, any systems acting through "kneecaps" (one or more) or related); Articulatory axes which are associated with one or more dynamic or dynamic rebound systems (defined as such) such as for example springs (one or more relative to the size of the articulation system) interacting dynamically with and / or towards the elements 25 (one or more), plastic abutments, abutments (or alternatively referred to as longitudinal members or wings if appropriate); All articulations using axial systems such as joints of articulatory or related axes type and / or having a dynamic mobility capability can associate with their respective axes, one or more mechanisms of the type bearings, and in particular for example bearings said "ball" (or "bearings" ..etc) to facilitate mechanical mobility; (Similarly, this type of bearing mechanism can be associated more or less directly with rebound systems such as springs type associated with the kind of <joints in question). These bearing systems will be especially associated, as 2945956 -7-

it is the classic way, on and / or at the periphery of these different types of axes to enclose them within them. These bearing systems may be of a nature that does not allow corrosion or mechanical pollution from outside which would come in particular from the marine environment, such as sand, particles, etc. All of these factors potentially associated , of course aiming to create a dynamic mobility in view of the rest of the device. All these systems associated with these elements (one or more) plastic abutments, abutments, (or else designated as spars or fins if appropriate) may be removable and / or adjustable if necessary by associating screws to their sets (and potentially potentially and for example through one or more walls and thus potentially joining several of these elements). According to particular embodiments: the elements (one or more), plastic abutments, abutments (or else longerons or fins if appropriate) are divided or subdivided into pieces which are connected to each other either by an articulation system a system that can consist of one or more articulations, and which makes it possible to obtain a "twisting" effect and / or "bending" of their structures; are still connected by several different articulation systems associating for the same purpose; actuating the device by the user producing the dynamic actuation and / or twisting of one or more of these elements; this makes it possible to stick ergonomically, mechanically and flexibly to the movement. The articulation system of these pieces may be in the form of axes, also called articulatory axes (one or more in relation to the size of the articulation system), and therefore potentially associated with a or several other different articulation systems. Also meant as axes are any systems acting through "kneecaps" (one or more) or related. 2945956 -8-

The hinge system (s) may combine one or more rebound systems such as springs (one or more with respect to the size of the hinge system) interacting dynamically with and / or toward the pieces; This principle is particularly devolved (but not exclusively) to be added to the articulatory modes using axes or axial principles. The articulating systems (one or more) in question may be in the form of articulatory folds (one or more) acting according to a "folded" principle of material, and potentially associable with one or more several other different articulation systems. This or these articulatory folds may show a material nature to the qualities capable of favoring a particular flexibility and thus of greater torsional yields; The use of textile-type materials and / or soft and / or elastic type coatings can be envisaged, for example. However, again, in order to achieve an increased level of flexibility even with foldings, it may be possible for them to be also constituted in an area using in part or in whole a thickness less than that of the average of the rest of the elements ( one or more), plastic stops, abutments, (or longerons or fins if necessary). In another way, the divided or subdivided pieces 25 may be provided with one or more elastic rebar type rebound systems associated with the elements (one or more), plastic abutments, stops, (or rails or fins where appropriate) by connecting two or more pieces together; This system said elastic armatures can be placed and relatively along these pieces and aiming to induce a dynamic effect to the process of articulation thereof once the entire device put into action. This system can be in one continuous piece, or in several pieces between several pieces; It forms, in addition to a rebound system, potentially a coherent secondary articulatory system accompanying the movement printed by the swimmer. 2945956 -9-

All these articulations using axial systems such as articulations of the articulated axle or related type, can associate with their respective axes, one or more mechanisms of the type bearings, and in particular for example 5 bearings called "ball", so to facilitate mechanical mobility; (Similarly, this type of bearing type mechanisms may associate more or less directly with rebound systems such as springs type associated with the kind of <joints in question).

These bearing systems will be especially associated, for example, as is the conventional way, on and at the periphery of these different types of axes to enclose them within them. These bearing systems may be of a nature that does not allow corrosion or mechanical pollution from outside which would come in particular from the marine environment, such as sand, particles. The device is intended for underwater sports. (or any aquatic activity), but still, rescue at sea and along the coast.
