Abstract

The invention relates to a helmet (1) formed by two half-bodies (2, 3), each formed by an outer casing (5 and 7) comprising built-in shock-absorbing material and a complementary shock-absorbing material (4 and 6), each half-body comprising a series of recesses and projections. The projections comprise built-in channels arranged such that a continuous groove (11) is formed once the recesses and the projections are coupled to one another, as well as comprising one or more safety and retaining channels which prevent the band (9) from being reinserted into the channel (11) once it has been removed in order to separate the half-bodies and which retain the band inside the groove. In addition, the outer casing (5 and 7) and the absorbing material (4 and 6) of each half-body (2, 3) are shaped to allow the half-bodies to fit together vertically and horizontally. The resulting helmet is a divisible helmet, the parts of which cannot be reassembled once they have been separated by removing the band joining same, with danger being avoided and the structural reinforcement being improved owing to the dimensions of the band, which are similar to the span of the channel.

Description

DIVISIBLE HELMET NOT RE ASSEMBLABLE

DESCRIPTION OBJECT OF THE INVENTION

[0001] It is an object of the present invention, as well as, as the title of the invention states, a divisible helmet that cannot be re-assembled, that is, refers to a protective garment worn on the head and generally made of metal or some other resistant material, typically for the protection of the head against impacts or collisions at high speed, which can be separable and does not allow a subsequent reassembly. The helmets can be open or semi-integral, covering at least the crown, forehead and temples, or integral helmets that also cover the chin or chin. There are other helmets, known as convertibles, that allow the chin guard to rotate upwards, remaining as a semi-integral. The helmet of the present invention is of any of the types mentioned. [0002] The present invention characterizes the special constructive form that the helmet presents in a way that allows to achieve a divisible helmet, that is to say that it can be removed in the event of an accident of the user's head without moving the head, or fractioning, or twist the neck which, in addition, by its constructive form prevents, once separated, being able to reassemble the parts into which it has been separated and which, in addition, is structurally reinforced. In addition, it can be manufactured robotically.

[0003] Therefore, the present invention is within the scope of the means of protection of the head, particularly helmets and more precise way between the helmets separable or divisible into parts in order to facilitate the removal of the head. BACKGROUND OF THE INVENTION AND TECHNICAL PROBLEMS TO BE SOLVED

[0004] In the state of the art different helmets are known that allow them to be removed from the head without the need to fractionate the head of the wearer, since they allow to be separated into at least two parts, facilitating the removal of the helmet and access to the head of the user.

[0005] These helmets, in general, as described in WO2014041215. It has two nesting bodies carrying complementary entrances and projections, so that both the entrances and projections of the outer shell and the impact-absorbing material of each of the half-bodies are complementary, so that they allow the fitting and coupling of each half-body by counting also with a series of rigid protuberances of the housing itself and perforations defined in each half-body so that embedded they define a continuous conduit through which a plate is passed in order to join both parts.

[0006] The helmet described in said prior art patent has two basic layers, a rigid outer shell and an impact-absorbing inner padding. To create the channel through which a strip moves, rigid protuberances or wedges were used that had a gap at its end to close and form the continuous channel through which the strip moves. By penetrating these hard bulges deeply into the absorbing material, their thickness is reduced by more than 50%, also reducing their ability to dampen bumps, and in addition, in case of punctual impact on said bumps, they can perforate the thin layer of material absorber that separates them from the skull, digging into it. [0007] The hull thus defined does not comply with the intended purpose of safety for the user, since it presents dangerous risks such as the reduction of the layer of absorbing material in an alternative way, multiplying the danger that these rigid protuberances of the same material of the carcass of the hull and as an extension of this they drill the shock absorbing material and inserted to create the cane! through which the connecting strip of the two halves circulates pierce the skull and enter the brain.

[0008] In addition, its manufacturing process is the traditional one, subject to human errors, it is ideal and with high costs.

[0009] Furthermore, said hull has aspects that can be improved, such as that the union of both semi-bodies is limited to a plate of union of undefined dimensions, being "loose" with respect to its channel; on the other hand, the channel through which the plate runs lacks retention means thereof, so that the plate could leave its housings by simple vibration during use or insignificant impacts, in addition, the clearance of the strap with respect to the channel, will produce the movement between both semi-bodies, allowing the entry of water, wind and external noises .., but the most serious thing is that they are helmets that once opened by the emergency health services after an impact or accident, would allow the reassembly and the reutiíizactón of the same, with the consequent danger, since the normal after an impact, is that they have been structurally weakened.

[00010] The present invention avoids all these problems by describing a divisible, non-re-assembled helmet, which:

Eliminates dangerous bulges in the housing.

• incorporates gutters and plates of tight dimensions between them. • It has different safety gutters that incorporate an anti-reassembly system of the helmet, so that, once the plates have been removed, they cannot be reintroduced.

• The safety gutter system has means that, in addition, exert pressure on the pietins, retaining them without impeding their extraction by emergency services.

• The gutters are embedded and surrounded exclusively by shock absorbing material, which provides a double buffer zone and constant thickness, one at the top, between the gutter and the housing, and another, at the bottom, between the gutter and skull and / or head. This, together with the fact that the gutters are located parallel to the housing, without protrusions or rigid material projected into the hull, completely eliminates the risk of cranial perforation in case of impact.

• This helmet can be manufactured robotically, as well as vehicles and other goods are made, reducing the risk of human error, multiplying its production and reducing costs.

DESCRIPTION OF THE INVENTION

[00011] The object of the present invention is a divisible, non-re-assembled helmet that, in addition, is structurally reinforced, that is, a helmet that can be separated or divided into the parts that form it, preferably two and which, due to its construction, geometry and safety gutters prevents the re-assembly or union between both parts again after being separated by the emergency health services, where the safety gutters that make up the groove are embedded and surrounded by shock absorbing material, where some gutters of safety hold the strap or plate subject to avoid involuntary exit of the helmet, due to vibrations and / or insignificant blows, which, in addition, firmly and solidly joins their parts »offering a reinforcing structure! integral to the entire helmet, which can be manufactured robotically.

[00012] Each one of them (as halves that form the hull, which we will call hereinafter half-bodies, have a union profile provided with complementary entrances and projections so that the semi-bodies facing each other by the union profile are perfectly fitted forming an integral body! dei hull [00013] In general, the projections of each half-body have a canaieta / s urta / s that will form a future groove, inserted so that, collected the incoming in the projections, a continuous groove is defined and, in addition, counts with means that prevent re-introducing the strip or plate in the groove, once removed to separate the half-bodies.

[00014] Each of the half-bodies is designed in such a way that, in the profile of union with the other half-body, it has a design such that the housing with part of the absorbing material defines protruding projections in seats or in some recesses of the material shock absorber or, briefly, absorber material of said half-body, each half-body having complementary entrances and protrusions of the ios defined in the joint profile of the other half-body,

[00015] Each of the protrusions defined in the housing of each half-body has a part of it firmly incorporated and adhered to it! absorber material and in each of these projections of absorber material of each half-body there are gutters, so that the whole or combination of one type or several types of gutters, we will call continuous grooving or, simply, grooving, so that, collected the housing with part of the absorber material with The remaining absorber material of each half-body and then the half-bodies between each other. they define a continuous groove through whose interior runs a longitudinally flexible but rigid strip or plate against transverse forces, of similar section to the space available in it, which fits into the interior space of the groove forming a unique and integral body that makes the times of a beam, for example, of steel, kevlar, etc., that runs from the front to the back or neck, and, if it is an integral helmet that also protects the jaw, fulfills the same reinforcement objective to the helmet chin guard.

[00016] Therefore, one can speak of a fitting according to a vertical direction of each of the incoming and outgoing defined in the parts of each half-body, in addition to a fitting according to a horizontal direction of each of the defined incoming and outgoing in the union profile of each half body.

[00017] Thanks to the structural characteristics of each semi-body and to the fixing and retention of the strap within the channel, it is possible to provide the hull with a greater overall structural rigidity and also improves the union between the absorber material and the housing.

[00018] On the other hand, and in order to prevent the reuse of the hull once its two semi-bodies have been separated by removal of the strap, it has some means to prevent the reintroduction of the strap and that in a possible embodiment, they would consist of the provision of two folded tabs towards the interior of the free space of the gutter with the free edge of the tabs, either according to the longitudinal direction of the gutter or according to the transverse direction of the gutter using mounting pieces arranged under the folded tabs and which they are pushed and displaced by the end of the strap in their first step through the gutter and, consequently, by the rest of the grooving until its exit to the outside or its deposit in the gutter provided for that purpose and that prevent the re-entry of the strap once removed.

[00019] Said folded eyelashes, in addition to fulfilling the function described once the hull is attached, hold the strap inside the channel when exerting pressure on it. Doing so prevents it from moving or moving inside! channel causing its involuntary exit of the helmet by vibrations or insignificant blows and, in addition, they prevent that it vibrates in its interior with the sudden movements, the wind, etc., as well as lateral displacements between the half-bodies.

[00020] In another alternative embodiment, in order to prevent the reintroduction of the strap inside the channel, the groove can have one or more type 3 gutters, which will be defined later, which has a thickness recess in one of its upper ends that define some steps in their union with the following gutters and in the opposite direction to the advance of the strip. In another possible embodiment, which would prevent the reintroduction of the strap inside the groove channel and, in addition, would fulfill the purpose of retaining it inside, the groove may have one or more type 7 gutters, which it will be defined later, that presenting the characteristics of the previous type 3 gutters, incorporates a flange folded into the free space of the gutter, with the free edge of the flange according to the transverse direction of the gutter.

[00021] Also, another possible way to provide safety to the helmet preventing the reintroduction of the strap is by using a flange folded into the type 4 raceway, which will be defined later, and with the free edge arranged so transverse to the longitudinal direction of this channel and therefore of the groove. [00022] Therefore, as already mentioned, when the term continuous grooving is mentioned or, simply: grooving, reference is made to the assembly or combination of one type or several types of gutters that form a continuous conduit defined by whose interior The strips run and stay firmly, and you can count on different types of gutters:

[00023] - Type 1, safety and retention gutter, provided with tabs arranged with the free edge thereof according to the longitudinal direction of the strap, which prevents reintroduction of the strap inside the gutter once the hull is opened and which also retains the strap inside. [00024] - Type 2, safety and retention gutter, provided with tabs arranged with the free edge thereof according to the cross-sectional direction facing each other, which prevents reintroduction of the strap inside the gutter once open the helmet and also retains the strap inside.

[00025] - Type 3, security and blocking gutter, provided with a recess in the upper part of one of its ends that defines a scaling at its junction with the following gutter. This type of gutter 3, is also designed to prevent reintroduction of the e! inside the groove once the helmet has been separated by removal of the strap and lacks retention means,

[00026] - Type 4, safety and retention gutter, provided with at least one flange with the free edge of the flange arranged towards the inside of the gutter and transverse to the direction thereof, which prevents the reintroduction of the strap inside of the gutter and also retains the strap inside. [00027] -Cannel type 5, standard safety, which is completely smooth inside and out, without any means of retention. [00028] -Cutlet type 6, anti-extraction / anti-return. which seeks to prevent the recovery and / or extraction of the assembly parts used with the first two types of gutters.

[00029] - Channel 7, security, retention and blocking channel, provided with the same recess said of the type 3 channel and, in addition, has a flange folded into the free space of the channel, with the free edge of the flange according to the transverse direction of the channel.

[00030] All the eyelashes with the type 1, type 2, type 4, type 6, and even type 7 gutters are preferably made by means of a die, or any other similar method.

[00031] Thanks to the construction characteristics that this helmet presents, it can be manufactured robotically, that is to say in an automated way, with the consequent saving of material, labor, costs and human errors.

[00032] Unless otherwise indicated, all the technical and scientific elements used herein have the meaning normally understood by the person skilled in the art to which this invention belongs. In the practice of the present invention, methods and materials similar or equivalent to those described herein can be used.

[00033] Throughout the description and the claims the word "comprises" and its variants are not intended to exclude other technical characteristics, additives, components, materials or steps. For those skilled in the art, other objects, advantages and characteristics of the invention are they will give part of the description and part of the practice of the invention.

[00055] Figure 19 shows a front view of a hull and the reservoir or cavity of the type 6 gutter, for the definitive loosening of the unrecoverable mounting parts, begun for the first step of the connecting strip of the two half bodies , arranged at the front of the helmet or chin guard.

PREFERRED EMBODIMENT OF THE INVENTION. [00056] In view of the figures, a preferred embodiment of the proposed invention is described below:

[00057] In Figure 1 we can see a helmet body (1) formed by two half bodies, a right half body (2) and a left half body (3), which fit to be assembled forming the helmet body (1), where each of the semi-bodies are intended to provide protection to the area of the skull and, in case it was an integral helmet as represented, and / or convertible, although not represented, also to the area of the jaw or chin guard (8 ).

[00058] The right half-body (2) comprises an outer shell (5) and an absorber pad (4), while the left half-body (3) comprises an outer shell (7) and an absorber pad (6), presenting a geometry both sides are such that a fit and coupling can be defined as well as a structural reinforcement for the whole hull.

[00059] In Figure 2, it is worth noting the presence of a first connecting strip (9) that is arranged in the part that goes from the front to the neck and, although not shown, its assembly is possible in the opposite direction, counting in one end with a projection or handle (9.1); also counts on the case of the integral and / or convertible helmets, with a second strap (10) connecting the half bodies in the part of the chin, and which is provided with a shoulder or handle (10.1). [00060] Said projection or handle (9.1) would have previously been incorporated into the strap when the strap is introduced by the groove in the direction from the front to the neck, otherwise, that is to say that it was introduced from the neck towards the forehead, it would be necessary coupling said protrusion subsequently to the end that would protrude from the front, to be pushed the strap mechanically from the neck area enough to couple it, reintroducing it later, also happens with e) protrusion or handle (10.1) of the second strap (10), to be present if it is introduced from the groove from the nose to the chin. Otherwise, that is, by introducing it from the area of the chin towards the nose, the projection is collected to the end that would protrude near the nose, as described for the previous case.

[00061] Each of the half-bodies (2,3) presents in the joint profile a series of incoming and outgoing defined in such a way that it allows a perfect coupling, which can also be tongue and groove, of the two half-bodies.

[00062] In Figure 3, it is observed that the right half-body (2) has protrusions (2.1) and recesses (2.2), while the left half-body (3) has protrusions (3.1) and recesses (3.2) with a geometry such that the projections (2.1) of the right half-body (2) fit the recesses (3.2) of the left half-body (3) and into the recesses (2.2) of the right half-body fit the projections (3.1) of the left half-body.

[00063] The same happens in the jaw protection zone »that the right half-body (2) has at least one chin bar protrusion (2.3) and, at least, a chin guard (2.4) and the left half body (3) have at least one chin guard (3.3) and at least one chin bar (3.4). [00064] In this figure 3 the presence of a continuous groove or, in short, groove, of the hull (11) that runs from the part of the front towards the back or area of the neck or vice versa, and a groove can also be observed continuously or, briefly, grooved, of the chin guard (12) that runs in the jaw protection zone. Both grooves (11) and (12) have dimensions such that they allow the housing and retention of the strap once housed inside.

[00065] In this figure, you can see the first strap (9) and the second strap (10) both with their respective projections or handles (9.1) and (10.1), with said first and second strap (9) and (10) ) dimensions such that they fit into the groove where they are housed so that a compact body is formed that functions as a rigid beam. [00066] In Figure 4, a first constructive form of each half-body is shown which is that under the projections (7.2) of the housing of the left half-body (7) there are glued projections (7.1) of impact absorbing material, or simply, absorbing material, of the left half-body, provided with first channels (11.1) of a groove. The impact absorbing material (6) of the left half body, in its joint profile, has projections (6.1), recesses (6.2) and seats or recesses (6.3) in each skip (6.1), with second channels being arranged (11.2) in the upper part of each of the projections (6.1) so that, the upper part of the absorber material attached to the housing is coupled with the bottom, that is, with the rest of the absorber pad, the projections (7.1) are arranged on the seats (6.3) and the first gutters (11.1) aligned with the second gutters (11.2) forming a first groove part of the future and complete continuous groove (11) Exactly the same happens with the right half body (2), in which under the protrusions (5.2) of the housing (5) there are glued projections (5.1) of absorber material that are provided with a third channel (11.3) of the groove (11), while the absorber material (4) in its joining profile, has projections (4.1) , some recesses (4.2) and some seats or recesses (4.3) in each projection (4.1). fourth grooves (11.4) of the groove (11) being arranged in the upper part of each of the projections (4.1) so that the upper part of the absorber material attached to the housing with the lower part is connected, that is, with the The rest of the absorber material, the projections (5.1) are arranged on the seats (4.3) and the third channels (11.3) aligned with the fourth channels (11.4), forming a second part of future groove and complete continuous groove (11) .

[00067] In Figure 5 an alternative embodiment is shown, in which in the left half body, just as in the previous case, projections (7.1) are attached under the projections (7.2) of the housing (7). of absorber material provided with channels (11.1) of the groove (11), while the absorber material (6) has projections (6.1) and recesses (6.2), counting the projections (6.1) in their upper part with gutters (11.2) of the groove (11), so that coupled with the upper part of the absorber material attached to the housing (7), the projections (7.1) are embedded in the incoming ios (6.2). and the gutters (11.1) aligned with the gutters

(11.2), forming a first groove part of the future and complete continuous groove (11).

[00068] In a complementary manner, the same applies to the right half-body (2) in which there are underneath (5.2) of the housing (5) glued projections (5.1) of absorber material and provided with a gutter (113), while the absorber material (4) in its joint profile has projections (4.1), recesses (4.2), being arranged gutters (11.4 ) in the upper part of each of the projections (4.1) so that the upper part of the absorbing material attached to the housing is coupled with the lower one, that is, with the rest of the absorbing material, the projections (5.1) are arranged in parallel with the recesses (4.2) and the gutters (11.3) aligned with the gutters (11.4) forming a second groove part of the future and complete continuous groove (11).

[00069] Once each of the parts of the right and left half-bodies is coupled, the front assembly of the joining profile of both half-bodies is carried out, all the channels being aligned

(11.1), (11.2), (11.3) and (11.4) forming a continuous groove (11).

[00070] The same principles and embodiments are applicable to the chin guard, in which, also, after the coupling of the housing provided with part of the absorber material with the rest of absorber material of each half-body, and assembled both half-bodies, form a continuous groove (12) of the chin guard.

[00071] That is, in both embodiments, each of the half-bodies has a housing with a profile with recesses and projections having the enclosure incorporated or attached firmly part of the matter! absorber, presenting a complementary geometry of the rest of the absorber material of said half-body and with an external profile such that it allows the fit with the profile of the other half-body, defining a continuous groove (11) and / or (12). [00072] Accordingly, one can speak of a fitting according to a vertical direction of each of the entrances and projections defined in the parts of each half body, in addition to a fitting according to a horizontal direction of each of the entrances and projections defined in the union profile of each half body.

[00073] In Figures 6 and 7 the left half-body can be seen completely where the complementarity of the outer shell with the rest of the absorbing material can be seen. The step of! Is shown in figure (7). first strap (9) and second strap (10).

[00074] In Figures 8 to 16 the different types of gutters used to form some types of continuous groove (11) and / or (12) can be seen and that, conveniently combined, will offer safety, by preventing the reintroduction of the strap into of the groove, and / or retention of the strap within the groove.

[00075] A first embodiment is shown in Figure 8 to prevent that once both semi-bodies (2) and (3) are separated by removal of the strips (9) and (10), both half-bodies can be reassembled again when the reintroduction of the strips.

[00076] This embodiment comprises a type 1 (30) safety and retention gutter, in which two punches are produced that produce two tabs (13) and (14), both folded into the interior space of the gutter, of so that the free end of the tabs (13) and (14) runs along the longitudinal direction of the groove, presenting opposite inclinations, using two wedged or beveled mounting pieces (15) and (16) that have a vertex coined (15.1) and (16.1) respectively in correspondence with the free end of the tabs, so that said vertices to introduce the mounting parts (15) and (16), lift the tabs aligning them with the internal contour of the groove, which will subsequently allow the passage of the strap.

[00077] Said minted pieces (15) and (16) are housed under the tabs inside each type 1 channel, included in a continuous groove (11) and / or (12) before the first passage of the strap (9) ό (10) during the hull manufacturing process, in only one possible assembly, so that in the process of introducing the strap (9) or (10) it pushes and drags one of the pieces (15) or (16) to push the other, eventually exiting the outside of the helmet and being recovered by the manufacturer or staying both at the opposite end of the introduction of the strap (9) or (10) into the cavity or storage tank unrecoverable provided in the gutter type 6, when it exists in the embodiment.

[00078] In the case of the strap (9) being introduced from the nape towards the forehead and the strap (10) from the chin to the nose, the wedged mounting pieces (15) and (16) go outside by the front and nose respectively, while if the strap is introduced from the forehead to the neck or from the nose to the chin, they would be housed in a type 6 safety and anti-extraction / anti-tongue gutter, blind at its final end in a storage tank (17) and (18) ad doc for said parts, as seen in Figure 13A-13S, 13C, in relation to Figures 17 and 18, Alternatively they can go outside if other types are used of gutters at the end next to the neck or chin.

[00079] A second embodiment is shown in Figure 9 to prevent that once both half-bodies are separated from the hull by removal of the plates (9) and (10) it is not possible to reassemble both half-bodies by preventing the penetration of the Straps [00080] This second embodiment comprises a type 2 (31) safety and retention gutter, in which two dies are produced that produce two tabs (19) and (20), both folded towards the interior space of the groove, so that the free end of the flanges (19) and (20) is arranged transversely to the longitudinal direction of the groove, presenting opposite and opposite inclinations, using two prismatic mounting pieces (21) and (22) that can be accommodated under them and move through the interior of the channel and, later, through the rest of the groove, as shown in the sequencing of the advance of the strip in its introduction through the interior of the channel.

[00081] In both embodiments, those shown in Figures 8 and 9, the tabs (13) and (14) on one side and (19) and (20) on the other hand have a folding with opposite inclinations in order to prevent the introduction of the plate by either of its two ends.

[00082] The assembly parts, both minted (15) and (16) and prismatic (21) and (22), serve to allow the passage of the strips in their first and only factory assembly, so that a once expelled out of the continuous groove, according to one of the forms of assembly, or housed in the type 6 channel (s) of lost pieces, since it is impossible to recover or extract them, as shown in the figures 13A. 13B, 13C, and figures 14A, 14B, 14C according to another embodiment, the tabs (13) and (14), in one case, and (19) and (20) in the second embodiment would prevent the reintroduction of the strap by any of the ends of the groove., once extracted by the emergency services in accidents. If there is a type 6 gutter in the groove, it, by itself, already prevents the reintroduction of the strap from the neck and / or the chin due to its blind end. [00083] A third embodiment is shown in Figure 10 to prevent the reintroduction of the strap once it is removed in the separation of the hull half-bodies and comprising a type 3 (32) safety and blocking gutter, which as a lowered end (24) is observed which, in its connection with the next groove gutter, forms a step (25), represented in the upper detail, and which as and as observed in the lower detail, in the reintroduction of the strap (9) or (10) prevents the advance of the strap. [00084] Figures 10A and 10B show a detail of type 3 (32) safety and blocking gutter, which at one of its ends has an internal recess (24) so that coupled with other types of gutters (30) , (31), (33), (34) and / or (36) and, even, with another (32), define a scaion (25) that prevents reintroducing the strap,

[00085] Figure 11 shows a type 4 (33) safety and retention gutter, which seeks to prevent the reintroduction of the strap once removed, in addition to retaining and fixing the strap inside the gutter and, therefore, of the grooving, presenting for it a single flange (26), produced by a three-sided die cut, with the free edge inside the gutter and transverse to the direction of it. Depending on the orientation of the inclination of the flange (26), the strap may be introduced into this channel at one end or the other. [00086] Figure 12 shows a type 5 (34) standard safety gutter, which does not have any retention means, designed to complement any groove in any embodiment.

[00087] Figures 13A, 13B, 13C and 14A, 14B and 14C show the process of housing and storage of the cradled mounting parts (15) and (16) on the one hand, and the prismatic mounting parts (21 ) and (22) on the other hand, pushed by the strap (9) or (10) until it is housed in the storage (17) without the possibility of being able to recover. For this purpose a type 6 gutter (35) is used that prevents the extraction / recovery of the cradled mounting parts (15) and (16) or the prismatic mounting parts (21) and (22) For that purpose said type 6 gutters , they have tabs (23), the result of a three-sided die cut, folded inwardly thereto, so that they allow the introduction of the assembly parts but not their extraction and the final end of said type 6 gutter is closed (37), since when removing the strap (9) or (10), the tab (23) returns to the interior of the channel.

[00088] Figure 15 shows in detail a type 6 (35) safety and anti-extraction / anti-return gutter. which, as indicated, has a flange (23) folded towards the inside of the channel and with the transverse free edge! to the longitudinal direction of the gutter, presenting the blind end end (37), which defines a storage (17) where to accommodate fas assembly parts without the possibility of recovery or extraction.

[00089] Figure 16 shows in detail a type 7 (36) safety, fixing and blocking channel that shows that, as can be seen, it is a fusion of type 3 and type 4 channels in the same channel, so it counts with a folded flange (26) towards the interior space of the gutter, and a recess (24).

[00090] Figure 17 shows how the grooves (11) and (12) are formed by the succession of several types of gutters, Type 4 gutters (33) that prevent the reintroduction of the strips (9) or ( 10) once removed, and type 5 gutters (34). Since in this embodiment the strap / s must be introduced from the neck and / or the Chin, this access will be blinded later by welding or any other firm and resistant system.

[00091] In the embodiment shown in Figures 17 and 18, the ends of the strips (9) and (10) would have a shoulder or handle (9.1) and

(10.1) respectively that it would be protruding from the respective grooves.

[00092] The possibilities of assembly and combination of the different types of gutters to form the grooves would be, by way of guidance _: not limitative;

[00098] Thanks to the geometry of each one of the half-bodies and to the disposition of the different gutters in the projections and the nature of the same, to the parts of each half-body and the half-bodies being coupled together, a continuous groove is defined that runs longitudinally along the joint profile through the projections, continuous grooving that acts as a compact structural reinforcement beam, increased structural resistance, both impact and perforation, and also prevents vibrations and movement of a half-body Regarding the other. Said structural reinforcement is increased with respect to any other existing hull, by passing the connecting strip through both half-bodies so that it occupies all the available space of the channel, giving it the same resistance as a steel beam or material highly resistant to impacts.

[00099] Therefore, thanks to the characteristics described, it is possible to develop a helmet that prevents the reassembly of the two half-bodies once separated after removing the strap that joins them, maintains a continuous thickness of shock absorbing material, both for its part upper and lower, avoiding a reduction of absorbing material and avoiding specific reductions of matter! absorber and thus, the dangers of insertion or nailing of the rigid pieces in the skull for not being necessary and if dangerous, in addition, improves the structural resistance ai act the strap-channel assembly as a solid beam, without gaps that make the half-bodies vibrate and move laterally to each other. The accidental expulsion of the strap is also avoided: as well as its internal movement, in addition to preventing the entry of water or wind,

[00100] Sufficiently described the nature of the present invention, as well as the manner of putting it into practice, it is noted that, within its essentiality, it may be implemented in other embodiments that differ in detail from that indicated to title of example, and which will also reach the protection requested, provided that it does not alter, change or modify its fundamental principle.
