    FIELD OF THE INVENTION The invention relates to a jugular strap connector with variable rupture, and to a protective helmet provided with at least one such connector. State of the art
    Protective helmets used in the context of a sports activity or professional activity do not meet the same requirements.
    Indeed, in the context of a professional activity, a protective helmet must be able to be detached from the head of the user if a tensile force greater than a certain threshold is exerted on the cap of the helmet. For example, it could happen that a pruner is hanged by his helmet if it is hooked to a tree branch and he can not pick it up. The jugular strap could therefore strangle the wearer of the helmet.
    To prevent this type of danger, the helmet must meet stringent safety requirements. In particular the jugular strap must be able to disengage the cap if it is subjected to a tensile force greater than a certain threshold. The user's head is then released and the user can no longer be strangled by the chin strap.
    In Europe, this safety rule is governed by the EN 397 standard, which requires the manufacturer to manufacture protective helmets comprising at least one anchor point of the chinstrap on the cap which are configured to break when the chinstrap is subjected to a tensile force of between 150 and 250 Newtons.
    In the context of a sports activity, the main danger for the user is falling rocks. It is therefore fundamental that the protective helmet resists shocks and that the jugular strap remains attached to the cap so that the user remains properly protected.
    In Europe, a protective helmet used for a sports activity must meet the EN 12492 standard. This standard requires that the fastening system of the chinstrap on the cap may experience a tensile force of at least 500 Newtons without damage to the helmet. protection.
    These two standards are incompatible with each other. Therefore, a user in need of a protective helmet in the context of a sports activity and as part of a professional activity must have not one, but two protective helmets.
    In addition, the manufacture of helmets requires the development of two types of products and the implementation of two different production lines.
    Object of the invention
    An object of the invention is to provide a jugular strap connector capable of adapting to the two types of constraints mentioned above, so as to allow the use of the same helmet in the context of a professional activity and as part of a sports activity. For this purpose, the connector comprises: a first piece intended to be connected to a helmet cap, a second piece intended to be removably mounted on the first piece, a connection element mechanically connecting the first piece and the first piece. second piece, so as to form a first mechanical connection, • a movable element moving between first and second positions, and configured to: • prevent the separation of the first and second parts when said parts are subjected to a first threshold traction force when the movable element is in the first position, • enabling the first and second parts to be detached when said parts are subjected to a second tractive force of a threshold intensity lower than that of the first tractive force, when the moving element is in the second position.
    According to a specific embodiment, the connection element may comprise an independent part having a first end and a second end opposite the first end, the first end being connected to the first part and the second end being connected to the second part. . In this case, the connection element can be configured to allow the separation of the first and second parts by breaking the connection element when the movable element is in the second position.
    According to a particular embodiment of the invention, the connection element may be partially positioned in a housing of the first part, and cooperates with clipping means placed on the second part, so as to form the first mechanical connection.
    Furthermore, the movable member may be configured to form an additional mechanical connection between the first piece and the second piece when placed in the first position. For this, the movable element may for example cooperate with a stud placed on the connector. The movable member may further be rotatably mounted.
    According to a particular embodiment of the connector, it may comprise a closure element for closing a strap of a protective helmet and / or adjust its length. The invention also relates to a protective helmet comprising a cap, a jugular strap and at least one connector having the aforementioned technical characteristics.
    When the protective helmet comprises a single connector, the first threshold pulling force exerted on the chinstrap may be greater than 500 N, and the second threshold tractive force exerted on the chinstrap may be between 150 and 250 N, this traction force being applied between the helmet and the chinstrap.
    According to one embodiment of the helmet, the first piece of at least one of the connectors can be connected to the cap by means of an additional strap and the second piece of said connector can be connected to the jugular strap.
    According to an alternative embodiment, the first piece of at least one of the connectors can be connected to the jugular strap, and the second piece of said connector can be connected to the cap. The invention also relates to a method of assembling a connector having the aforementioned technical characteristics. It comprises the following steps: • supplying the first part, the second part and the connecting element, • mechanically connecting the first and second parts by means of the connection element, so as to prevent the separation of the first and second parts when said parts are subjected to a lower tensile force than the second threshold traction force.

    detailed description
    According to one embodiment of a connector 1, it comprises a first part 2, a second part 3, a connection element 4, and a movable element 5.
    The first part 2 comprises an attachment zone 2a intended to be fixed directly or indirectly to a protective helmet cap, and is for example intended to accommodate at least one strap, as will be seen later. The second piece 3 also comprises one or two attachment zones 3a intended to be fixed directly or indirectly to the cap of the helmet and intended for example to cooperate with one or two straps. The attachment zones 2a and 3a advantageously have the shape of a slot to facilitate the connection with a strap.
    In the following, the longitudinal axis of the connector 1 is defined as the axis of the strap housed in the attachment zone 2a. It is represented by the axis AA in FIGS. 2 to 4.
    The first and second parts 2 and 3 are removably mounted relative to each other, they can be assembled and disassembled without rupture. Advantageously, a part of the first part 2 slides inside a cavity of the second part 3 and / or part of the second part 3 slides inside a cavity of the first part 2. This sliding assembly makes it easier to define the forces to be applied to the connection element 4.
    The first and second parts 2 and 3 are mechanically connected by means of the connection element 4, so as to prevent the separation of the first and second parts.
    In the illustrated embodiment, the first part 2 comprises two slots 2b located along the longitudinal axis, and defining a central portion 2c. An embodiment with a single slot is also conceivable. The second piece 3 comprises a base 3b on which there is a housing 3c. The central portion 2c of the first piece 2 and the housing 3c of the second piece 3 have dimensions adapted to allow their interlocking into one another, the side walls of the housing 3c sliding in the slots 2b. An alternative embodiment in which the first part 2 has more than two slots 2b is also conceivable. The connection element 4 makes it possible to mechanically connect the first part 2 and the second part 3. It can comprise an independent part of the first and second parts 2 and 3. This part has for example the shape of an H, but other suitable forms are also possible, a circle, a square, a rectangle. In an advantageous embodiment, the connecting element 4 is used as a tensile specimen, that is to say it forms a first mechanical connection between the parts 2 and 3 until the part is broken under the effect of a pulling force (see Fig. 5). The connection element 4 is therefore a fuse piece that can be replaced in the event of a failure of the connector 1. The break of the connection element 4 makes it possible to rapidly detect the stress on the connector beyond a threshold value.
    According to an alternative embodiment, a system may be provided so that the connecting element 4 is released by the first or the second part when a threshold traction force is reached without the connection element 4 being broken.
    According to another variant embodiment, the connection element 4 can be an integral part of one of the first or second parts 2 or 3, in which case the whole of the part must be replaced in case a break.
    In the embodiment illustrated in the figures, the connection element 4 is an independent part. A first end 4a of the connection element 4 is placed in a housing 2d located on the central part 2c of the first part 2. The shape of the housing 2d is advantageously complementary to the shape of the end of the connection element 4, so that the latter is held fixed along the longitudinal axis. When the central portion 2c of the first part 2 is engaged in the housing 3c of the second part 3, the connection element 4 is placed inside the housing 3c. The latter comprises clipping means 3d intended to cooperate with the connection element 4 in order to make a first mechanical connection between the first and second parts (see FIG.
    However, the clipping means may be replaced by a ramp ending in a flat forming a fixing zone. In this way, the connection element 4 ascends the ramp without a major effort being provided. The connection element 4 then falls into the fixing zone where a much greater force will have to be applied to remove it from the fixing zone or to cause the breaking of the connection element 4.
    In general, it is advantageous to use coupling means which require a first effort to initiate the coupling by moving the connection element 4 in a first direction, and a second force greater than the first force to eliminate this coupling. attempting to move the connecting member 4 in a second direction opposite to the first direction. The connection element 4 is for example mounted on the first part 2 or the second part 3. When sliding the first part 2 in the second part 3 or the second part 3 in the first part 2, the mechanical connection is created by means of the connection element 4.
    According to the particular embodiment illustrated, the clipping means correspond to 3d hooked fingers belonging to the side walls of the housing 3c. This embodiment has the advantage of being particularly compact and efficient.
    When the central part 2c provided with the connecting element 4 is introduced into the housing 3c of the second part, the connecting element 4 pushes on the hooked fingers 3d until the second end 4b of the element connection 4 exceeds them. The connection element 4 then forms the first mechanical connection between the first and second parts 2 and 3. It is impossible to remove the central part 2c of the housing 3c in breaking the connection element 4 (see FIGS. ).
    As a variant, the aforementioned coupling means may not be used. It is necessary in this case to disassemble the connector to come to place the connection element so as to achieve the mechanical connection between the two parts. This embodiment is less convenient.
    As indicated above, if the connection element 4 is stressed in tension beyond a threshold force, the first part 2 is separated from the second part 3.
    When the user tries to resist this pulling force or on the contrary to yield to a lower effort, it is advantageous to provide means for modifying the value of the uncoupling effort. The movable element 5 is used to modify the mechanical connection that exists between the first part 2, the second part 3 and the connection element 4. The movable element 5 can be placed at least in a first position or in a second position. position.
    In a first case, the mobile element 5 is configured to make or eliminate a direct mechanical connection between the first part 2 and the second part 3. This mechanical connection is advantageously used to avoid stressing the connection element 4 and to withstand a greater tensile force than the mechanical connection formed by the connecting element 4. In this way, the connector 1 is able to withstand greater load.
    In a second case, the mobile element 5 is configured to modify the mechanical connection between the first part 2 and the second part 3 by means of the connection element 4. In this embodiment, the connection element 4 comprises for example a gripping zone for the first part 2 and several different gripping zones for the second part 3. The different gripping zones make it possible to put under stress different zones of the connection element 4.
    In another case, the movable member 5 is configured to move one end of the connection element 4 so that the latter cooperates with additional coupling means. By way of example, the additional coupling means may be arranged above or above the coupling means. The additional coupling and coupling means are both formed by clips forming clips. The two coupling means are configured to have different tensile strengths in cooperation with the connection element 4. For example, the coupling means are configured to withstand beyond the breaking threshold of the connection element 4 while the additional means are configured to allow a release of the connection element 4 before breaking. The movable element 5 can therefore be configured to move the additional coupling and coupling means so that the latter fix the uncoupling thresholds between the first and second parts 2 and 3. The movable element 5 can also be configured to moving the connection element 4 so that it is coupled to the coupling means or the additional coupling means.
    It is still possible to provide that the movable element 5 is configured to apply a stress on the connection element 4 in order to stop working the latter in traction, but for example in flexion. The breaking force is then modified.
    According to the embodiment illustrated in Figures 1, 2 and 3, the movable member 5 is positioned on the upper wall of the housing 3c (see Figure 2). The lower face 5a of the movable member 5 is defined as being in contact with the upper wall of the housing 3c, and the upper face 5b as being the opposite face to the lower face 5a. The movable element 5 is rotatably mounted relative to the assembly comprising the first part 2, the second part 3 and the connecting element 4. The rotational assembly is preferred to a translation assembly because the probability of tilting between the first and second positions unintentionally is lower.
    To allow rotation of the movable member 5, the upper portion of the housing 3c has a hole cooperating with a projecting portion 5c positioned on the lower face 5a of the movable member 5. The movable member 5 is able to move between first and second positions. In the particular embodiment illustrated in the figures, the movable element 5 can rotate 180 °. The user can move the part manually or using a tool. A notch 5d may for example be provided to rotate the movable member 5 with a coin. Rotating an angle greater than or equal to 90 ° is advantageous for distinguishing the first and second positions as this reduces the risks of unintentional actuation. The movable element 5 advantageously comprises first and second ends 5e and 5f, for example opposite along the longitudinal axis of the connector 1. The first end 5e of the movable element 5 has a stop orthogonal to the longitudinal axis, while the second end 5f is devoid of it.
    The abutment surface of the first end 5e is intended to cooperate with a stud 2e present on the central portion 2c of the first piece 2. When the central portion 2c is inserted into the housing 3c, the second stud is inserted into a notch 3e placed on the upper wall of the housing 3c. The notch 3e is advantageously placed along the longitudinal axis of the connector 1. The stud 2e thus projects through the housing 3c.
    When the movable element 5 is placed in the first position (see FIG 2), the abutment surface of the first end 5 e cooperates with the pad 2e, so as to prevent the separation of the first and second parts 2 and 3 when they are subjected to a first threshold traction force. The abutment surface of the first end 5e and the 2nd pad form an additional mechanical connection between the first and second parts 2 and 3, and prevents the power of the connection element.
    When the movable element 5 is placed in the second position (see FIG 3), the 2nd pad plays no role because the second end 5f has no abutment surface. In this way, when the first and second parts 2 and 3 are subjected to a tensile force, it is possible to separate them for a second tractive force threshold of intensity less than that of the first tractive force threshold.
    Thus, the movable member 5 forms an additional mechanical connection between the first piece 2 and the second piece 3 when placed in the first position. The connector 1 can withstand tensile forces of greater intensity when the movable member 5 is in the first position than when it is in the second position.
    In the embodiment presented above, the movable element 5 does not form any mechanical connection when it is in the second position. However, it is conceivable to provide a movable member 5 forming a mechanical connection in the first and second positions, provided that the mechanical connection in the first position allows to withstand higher tensile forces than the mechanical connection in the second position.
    When the movable element 5 is in the first position, the connector 1 may advantageously withstand a first tractive force threshold along the longitudinal axis. In this way, for the helmet to be compliant for sporty use, it suffices to use a connector 1 such as the one just described, and to place the movable element 5 in the first position.
    When the movable element 5 is placed in the second position, it can advantageously allow the separation of the first and second parts 2 and 3 by breaking the connection element 4 (see Fig. 5). The second tractive force threshold allowing the separation of parts 2 and 3 can advantageously be between 150 and 250N. A protective helmet may therefore be suitable for use in the professional setting when a connector 1 is used, and the movable member 5 is placed in the second position.
    Of course, if the safety standards of the protective helmets for professional use and for sport use change, it is quite possible to modify the technical characteristics of the connector 1 in order to adapt its resistance to other threshold traction forces. For this, the shape of the various elements of the connector, and the material in which these elements are manufactured can be adapted to be more or less resistant depending on whether one places the movable element 5 in the first or in the second position.
    Advantageously, the movable element 5 can be configured to prevent the mechanical connection between the first part 2 and the second part 3 when it is in the first position. This precaution prevents the joining of the first and second parts of the connector 1 while the connection element 4 has been forgotten during assembly.
    According to a particular embodiment of the connector 1 (not shown), it may comprise a closure element for closing a protective helmet strap. The closing system of the protective helmet straps and the connector 1 then form one and the same element that the user must adjust according to the type of use that he envisages (professional or sports).
    FIG. 6 shows an embodiment of a protective helmet 6 equipped with at least one connector 1 such as that which has just been described. The protective helmet 6 also comprises a cap 7, and a jugular strap connected directly or indirectly, and removably to the cap 7 to allow the user to place the protective helmet 6 on his head.
    According to an embodiment as shown in Figure 6, the first part 2 of the connector 1 can be connected to the cap 7 via an additional strap, and the second part 3 can be connected to the jugular strap. According to an alternative embodiment not shown, it is conceivable that the first part 2 of the connector 1 is connected to the chinstrap, possibly by an intermediate element such as an additional strap, and that the second part 3 of the connector 1 is connected at the cap 7.
    According to the embodiment illustrated in FIG. 6, the protective helmet 6 comprises a single connector 1 linked to a frontal strap 8a, to an occipital strap 8b and to the jugular strap 8c. More specifically, the jugular strap 8c is connected to the first piece 2 via the attachment zone 2a, and the front and occipital straps are connected to the second piece via the attachment areas 3a.
    In this embodiment, when the movable member 5 of the connector 1 is placed in the first position, the connector is configured to prevent the separation of the first and second parts when the jugular strap 8c is subjected to a threshold traction force F1 preferentially greater than 500 N. The pulling force F2 received by the connector is less than half, that is to say preferably greater than 250 N. The connector 1 is therefore configured to withstand forces equal to 50% of the force exerted between the protective helmet 6 and the jugular strap 8c.
    The rupture of the connector 1 frees the user's head when the movable member 5 is placed in the second position, that is to say in the context of professional use. The first and second parts 2 and 3 are then disengaged when the jugular strap 8c is subjected to a second threshold traction force of between 150 and 250 N. This prevents the user from being strangled by the jugular strap 8c if the cap 7 is stuck.
    According to an alternative embodiment, the jugular strap 8c can be connected on one side of the protective helmet 6 by the connector 1 and be fixed on the other side of the protective helmet 6 either directly or via an adjustment loop.
    According to another alternative embodiment (not shown), the protective helmet 6 may comprise several connectors 1 mounted in parallel on the same lateral side of the cap 7. In this case, the first and second threshold traction forces are divided by the number of connectors 1 mounted in parallel on the protective helmet 6.
    For example, the protective helmet 6 may comprise a first connector 1 connecting the cap 7 to the front strap 8a, and a second connector 1 connecting the cap 7 to the occipital strap 8b. The first and second connectors 1 are advantageously placed either on the left side of the cap 7 or on the right side. In this way, their breaks allow the release of the jugular strap 8c. In this case, the two connectors 1 are then configured so that the first tractive force threshold is greater than Fi / 4, that is to say preferably greater than 125 N, and so that the second tractive force threshold is between 37.5 and 62.5 N.
    It is therefore possible to provide a protective helmet 6 that can be used both for a professional activity and for a sports activity. The user will be careful to place the movable element 5 or connectors 1 in the first or second position depending on the activity performed to use the helmet under optimal conditions. The invention also relates to the method of assembling a connector 1 as just described. The method comprises the following steps: • supplying the first part 2, the second part 3 and the connection element 4, • mechanically connecting the first part 2 and the second part 3 by means of the connection element 4, so to prevent the separation of the first and second parts when said parts are subjected to a lower tensile force than the second threshold traction force.
