SIGNALING DEVICE WITH INTEGRATED ACCELEROMETER WORN ON THE BACK OF A MOTOR VEHICLE OPERATOR

Description

[0001] The present invention relates to a signaling device with an integrated accelerometer worn on the back of a user of a locomotion device.

[0002] The means of transport can be a land, air, or river vehicle. The signaling device is intended, in particular but not exclusively, for bicycles or motorcycles, and the signaling device allows users to be more visible to road users, especially motorists, for example, during changes of direction or braking.

[0003] Changes of direction and braking are traditionally signaled using two turn signals and a brake light positioned at the rear of motorcycles, at a height of approximately one meter. This arrangement of turn signals and brake light may not be sufficient to effectively alert other road users, particularly motorists. However, the safety of a motorcyclist depends on the visibility of the vehicle to other road users in its vicinity.

[0004] Some devices already exist, such as reflective strips or brightly colored vests, but these do not significantly increase the motorcyclist's visibility. Furthermore, these devices do not indicate braking or changes in direction.

[0005] Documents FR-A-2 870 505 and US 2017 / 257934 A1 describe signaling devices comprising, on the one hand, a transmitter intended to be connected to a control circuit of at least one primary signal of a cycle and, on the other hand, a receiver connected to at least one secondary signal, said receiver being capable of receiving a signal emitted by said transmitter so as to control the switching on and / or switching off of the secondary signal in a synchronous manner with the switching on and / or switching off of the primary signal.

[0006] In these documents, the secondary signal light is positioned on a support designed to be removable and worn on the user's back. The device can be worn like a backpack using straps around the user's shoulders.

[0007] A problem arises when the signaling device is mounted backwards on the user's back. For example, if two signal lights are in the form of two turn signals (this is not an exhaustive list), the right turn signal could be on the left side of the signaling device, and vice versa for the left turn signal. This is very dangerous for operating the vehicle, as the user may not realize their turn signals are reversed, and drivers of other vehicles moving in the vicinity of the vehicle carrying the signaling device may be misled about the vehicle's impending lateral maneuvers.

[0008] The problem underlying the present invention is, for a signaling device worn by a user of a means of locomotion according to the prior art, to detect when the secondary signaling light(s) of a lateral movement indicate a reverse movement following a bad positioning of the signaling device on the back of the user.

[0009] To this end, the present invention relates to a signaling device intended to be removably placed on the back of a user of a vehicle, the back remaining visible in the environment of the moving vehicle, the device comprising, on the one hand, a transmitter intended to be connected to at least one primary signal light of the vehicle indicating a right or left lateral direction taken by the moving vehicle, and, on the other hand, a receiver connected to at least one secondary signal light integrated into the signaling device, said receiver being capable of receiving a signal emitted by said transmitter, the device comprising electronic means for signal processing and for controlling the switching on and / or switching off of said at least one secondary signal light synchronously with the switching on and / or switching off of said at least one primary signal light,characterized in that the electronic means incorporate an accelerometer and means for interpreting the accelerometer measurements enabling the detection of a right or left lateral variation in the direction of movement, the control means for said at least one secondary signal light including means for verifying that said at least one secondary signal light correctly indicates the right or left lateral direction followed by the user and the vehicle.

[0010] The technical effect is the immediate detection of a reversal of the lateral direction change signal, advantageously a flashing light compared to the primary signal on the vehicle. This can occur when the device is placed upside down on the user's back, advantageously the driver of the vehicle, which can confuse the vehicle following the vehicle and cause accidents.

[0011] Indeed, a system for detecting the direction of a secondary signal, which also serves as a turn signal, ensures that the user can always properly signal their lateral movements. Taking the example of turn signals (though not limited to them), if the user wears the device upside down, for example, by reversing the top and bottom, when the user uses the primary right turn signal on their vehicle, the left turn signal, acting as the secondary turn signal on their back, will illuminate. Thanks to the accelerometer, when the device is mounted upside down on the user's back and the turn signals are reversed, this will be automatically detected for the fastest possible correction.

[0012] The accelerometer is compact and does not significantly increase the device's weight. Detection of a secondary traffic light reversal relative to its associated primary traffic light is immediate and does not require the user to look behind them.

[0013] Advantageously, the electronic means include means for automatically reversing said at least one secondary signal light when the verification means determine that said at least one secondary signal light does not indicate the right or left lateral direction followed by the machine, so that said at least one secondary signal light correctly indicates the right or left lateral direction followed by the user and the machine, or the electronic means include means for informing the user that the right or left lateral direction indicated by said at least one secondary signal light is incorrect.

[0014] It follows that correcting a reversal can be immediate and automatic. This allows the mobility device and its user to continue moving without stopping. Another option is available to the user: correcting the reversal themselves by stopping and correctly placing the device back on their back. This may be preferable for long journeys but is not automatic.

[0015] The first automatic solution is preferred, but allowing the second solution after warning the user can be advisable. It is possible to combine the two solutions by automatically correcting the secondary traffic light reversal while simultaneously alerting the user to the problem, primarily so they are aware they have likely put the device on incorrectly.

[0016] Advantageously, the transmitter is connected to a control circuit of two primary flashing lights right and left of the machine and said at least one secondary signal light includes two secondary flashing lights right and left, the verification means detecting whether a secondary flashing light is in operation or not according to its power supply.

[0017] This is a preferred embodiment with two turn signals as primary and secondary signal lights.

[0018] Advantageously, the transmitter is also connected to a control circuit of at least one primary auxiliary signal light of the machine and the device further includes at least one secondary auxiliary signal light, said at least one primary and secondary auxiliary signal light being taken individually or in combination from a brake light indicating braking, a position light, a fog light or a hazard warning light.

[0019] A single transmitter can be used for various signal lights indicating different functions. The activation of a signal light in the vehicle is transmitted to the signaling device.

[0020] Advantageously, the transmitter has a current detector in the control circuit or circuits associated with the primary traffic light or traffic light, or the ignition information of a primary traffic light is transmitted by wire link to the transmitter.

[0021] Advantageously, the transmitter includes a dedicated battery, rechargeable by induction, by micro-cable via a USB plug or by cable connected to a battery of the locomotion device, a visual and / or audible indicator on the device informing of a low charge of dedicated battery for the transmitter.

[0022] The visual and / or audible indicator helps the user become aware that the signal is not being transmitted between primary and secondary traffic lights and that no signals are visible behind them. The visual indicator must be easily visible to the user from within their field of vision, and the audible indicator requires that the vehicle does not obstruct their hearing.

[0023] Advantageously, said at least one secondary signal light is in the form of a lamp or light-emitting diodes whose luminous intensity is variable according to external brightness.

[0024] In clear daytime weather, it is advantageous to reduce the light intensity so as not to dazzle the external environment of the locomotion device, for example, machines or vehicles moving near the locomotion device associated with the signaling device.

[0025] Advantageously, the device includes radar detection means for another locomotor in the vicinity of the locomotor for which the device is intended, with estimation of a distance separating the other motor from the device, and when this distance is less than a predetermined minimum safety distance between the two motors and stored in storage means provided in the electronic means, the control means of said at least one secondary signal light illuminate said at least one signal light with a specific intensity and / or periodicity recognizable to signal that the predetermined minimum safety distance between the two motors is not respected.

[0026] This increases safety and informs a user other than the driver of the vehicle, which is an auxiliary function of the signaling device according to the present invention. The signaling device serves to inform an external user that they are approaching the vehicle associated with the signaling device in a dangerous manner.

[0027] Advantageously, a hollow shell in two parts which can be removably joined together delimits an enclosed interior space which houses in a watertight manner at least one secondary signal light, the electronic means and at least one power supply for the electronic means and the receiver, the device comprising at least one adjustable strap passing through the shell and wrapping around the user's body with quick-release snap fastening means.

[0028] A protective case houses and safeguards all the sensitive components of the signaling device. This case is conveniently worn like a backpack. It can also be inserted into a jacket via a pocket or a closed compartment, such as one with a zipper. Alternatively, the case can be attached with adhesive strips or adjustable straps to the jacket. This jacket can be a protective vest that inflates in the event of an accident, known as an Airbag Vest.

[0029] Advantageously, the shell comprises a first portion of the shell forming a lid and a second portion of the shell forming a receptacle for the electronic means and said at least one power supply, the second portion of the shell being intended to be opposite the back of the user, the first and second portions of the shell fitting into each other with the first portion of the shell having an opposite face furthest from the second portion in the fitted position of the first and second portions of the shell with transparent areas opposite said at least one secondary signal light housed inside the shell, the shell being provided externally with at least two adjustable straps intended to attach the shell to the back of the user.

[0030] The signal lights are protected by being integrated inside the hull. The transparent areas act as spotlights. There may be internal reflectors within the hull to focus or redirect the associated light beam.

[0031] Advantageously, either the second portion of the shell is intended to rest against a portion of the user's back, the second portion of the shell or the entire shell with its first and second portions of the shell having four recesses paired in pairs for the passage of a portion of the strap of at least two adjustable straps, or a shell support is interposed between the second portion and the user's back, the shell support having a bearing face intended to rest against a portion of the user's back with, on a face of the shell support opposite to the face conforming to a portion of the back, quick attachment means of the self-adhesive strip type with the second portion of the shell, the shell support protruding from the shell when the shell is superimposed on the shell support by at least four arms,each branch having a recess for a portion of the strap of at least two adjustable straps, the branches and their recesses being laterally paired in pairs.

[0032] The straps act like backpack straps and hold the shell against the user's back when adjusted. Appropriate adjustments can be made based on the user's body shape and clothing.

[0033] Two embodiments are possible. In the first embodiment, the shell also acts as a support surface against the user's back. In the second embodiment, a specific part fulfills this role with a removable connection between the shell and this part, which is a shell support.

[0034] The shell support has the advantage of offering a larger support surface against the user's back and, where appropriate, of presenting this support surface shaped to the user's back, but this requires an additional part in the design of the signaling device as well as a new connection between the shell support and the shell, which increases the price of the signaling device.

[0035] Advantageously, each strap is adjusted to be intended to go around a respective shoulder of the user by passing under an arm of the user, each passage recess having a median stud extending in the middle and length of the recess being in the form of a rectangular parallelepiped having a longitudinal rounded face of lesser width, a portion of each strap going around the median stud around the rounded face leaving the opposite longitudinal face of lesser width free for each of the two recesses associated with it, each strap having two free ends respectively carrying a male or female snap-on means.

[0036] This allows for easy adjustment of the strap length and prevents a strap from slipping during the movement of the locomotion device.

[0037] Advantageously, each strap has an intermediate strap section oriented towards the other strap at the level of the snap-on means intended to be at the level of the user's chest, the two intermediate strap sections having a free end with complementary snap-on means for their joining.

[0038] Advantageously, the electronic means are in the form of a printed circuit board and the device has one or more systems fulfilling one or more of the following functions: a local navigation and geopositioning function, an interconnection function with a mobile phone having downloaded a suitable application, an electronic key function locking the start of the locomotion device when the signaling device is a predetermined distance away from the locomotion device or unlocking it when closer to the locomotion device than the predetermined distance.

[0039] The invention finally relates to an assembly of a locomotion device and a signaling device worn on the back of a user of the locomotion device, characterized in that the signaling device is as previously described, an emitter of the device being housed in the locomotion device or located near the locomotion device.

[0040] Other features, purposes, and advantages of the present invention will become apparent from the detailed description that follows and from the accompanying drawings, which are given by way of non-limiting examples and on which: there figure 1 is a schematic representation of a perspective view of the signaling device according to the present invention, the device comprising a transmitter, a casing integrating the electronics and a casing support equipped with straps for being attached to the back of a user of a means of transport, these elements being shown at a distance from each other, the figure 2 is a schematic representation of an exploded view of the casing of the signaling device according to the present invention, the transmitter and the casing support also being visible in this figure, the figure 3 is a schematic representation of a transmitter forming part of the signaling device according to the present invention, the figure 4 is a schematic representation of a printed circuit board intended to be housed in the casing of the signaling device according to the present invention, the figures 5 à 7 are schematic perspective representations of a shell cover, a shell receptacle, and the cover and receptacle nested one inside the other to form a closed shell forming part of the signaling device according to the present invention, the figure 8 is a schematic perspective representation of a hull support used in one embodiment of the signaling device according to the present invention, the figures 9 And 11 are schematic perspective representations from two different viewpoints of a part joining the two hull sections by creating an entry or exit port communicating with the interior of the hull in an embodiment of the signaling device according to the present invention, the figure 10 is a schematic representation of a perspective section of a shell according to an embodiment of the present invention, the shell having recesses for a respective strap used to attach the signaling device to the back of the user of the locomotion device.

[0041] By referring to all the figures and more particularly to figures 1 et 2 The present invention relates to a signaling device 1 intended to be placed in a removable manner on the back of a user of a locomotion device, the back remaining visible in an environment of the moving device.

[0042] The means of transportation can be a land-based, marine, or flying vehicle; the important thing is that it protects the user's back, primarily the driver's. While not exhaustive, land-based vehicles can include wheeled or tracked construction equipment, a motorcycle with at least two wheels, a snowmobile, or a platform personal transporter known as a "Stepway." Flying vehicles can include autonomous flying motorized units known as "Flyboard Air." Finally, the device can be a floating craft such as a jet ski or personal watercraft.

[0043] Device 1 includes a transmitter 2 intended to be connected to at least one primary signal light of the vehicle indicating a right or left lateral direction taken by the vehicle in motion, this transmitter 2 being able to be positioned in the vehicle.

[0044] Device 1 includes a receiver connected to at least one secondary traffic light 3d, 3g integrated into the signaling device 1, said receiver being capable of receiving a signal emitted by said transmitter 2.

[0045] Device 1 comprises electronic means for signal processing and controlling the switching on and / or off of at least one secondary signal light 3d, 3g synchronously with the switching on and / or off of at least one primary signal light. The primary signal light(s) are the conventional signal lights of the vehicle. This at least one primary signal light may advantageously and commonly be in the form of two flashing lights, but the two flashing lights may be combined into a single signal light, which is not preferred but falls within the scope of the present invention.

[0046] According to the invention, the electronic means incorporate an accelerometer and means for interpreting the accelerometer measurements, enabling the detection of a right or left lateral change in the direction of travel. The control means for said at least one secondary signal light 3d, 3g include means for verifying that said at least one secondary signal light 3d, 3g correctly indicates the right or left lateral direction followed by the user and the vehicle.

[0047] This may not be the case when the signaling device 1 is mounted in an inverted position against the user's back, advantageously when the top of device 1 is positioned towards the lower back and the bottom of device 1 is positioned upwards.

[0048] The accelerometer determines the direction in which a vehicle is moving. It doesn't detect a position, but rather an acceleration along one of three orthogonal axes. The accelerometer measures accelerations, changes in speed, and changes in position, including translational movements, which is currently used to identify a right or left lateral movement of the vehicle.

[0049] The accelerometer indicates that the vehicle has deviated to the right or left. It is then possible to check if the secondary signal, ideally a right or left turn signal, has correctly indicated this deviation, in which case the signaling device 1 is functioning correctly. Otherwise, the signaling device 1 on the user's back is adjusted or repositioned, either automatically or manually.

[0050] In the first automatic case, the electronic means may include means for automatically reversing said at least one secondary signal light 3d, 3g when the verification means determine that said at least one secondary signal light 3d, 3g does not indicate the right or left lateral direction followed by the vehicle, so that said at least one secondary signal light 3d, 3g correctly indicates the right or left lateral direction followed by the user.

[0051] For example, if it has been observed that the right turn signal illuminates during a left turn, this can be corrected so that the left turn signal illuminates for a left turn and the right turn signal illuminates for a right turn. The vehicle does not need to be stopped, and the user does not need to do anything.

[0052] A system for reversing the direction of 3D and 3G turn signals ensures that the user always sends the correct signals. If the user wears the signaling device 1 according to the present invention upside down, when they use the right turn signal, the left turn signal will illuminate for the driver behind. Thanks to the correction provided by the reversing system, whether the signaling device 1 according to the present invention is worn right-side up or upside down, if the user uses the right turn signal, the driver behind will always see the right turn signal.

[0053] This corrects the error in indicating the lateral direction being followed, an error that is dangerous for other vehicles following the vehicle equipped with the signaling device 1 according to the invention. This indication error was most frequently due to the signaling device 1 being worn upside down on the user's back.

[0054] In the second case of manual correction, the equipment and electronic systems include means of informing the user that the right or left lateral direction indicated by at least one secondary signal (3d, 3g) is incorrect. This can be done by means of a warning light and / or an audible signal. The user stops the equipment and correctly repositions the signaling device (1) on their back. This takes longer than automatic correction but ensures perfect positioning of the signaling device (1) on the user's back.

[0055] The signaling device 1 comprises a receiver, a transmitter 2, at least one secondary signal light 3d, 3g (lateral), preferably two flashing lights 3d, 3g (right and left), or a signal combining the functions of flashing lights 3d, 3g (right and left). It may also include several other secondary signal lights controlled indirectly by primary signal lights in the vehicle. The signaling device 1 may include one or more batteries for powering its electronic components and the signal light(s), as well as for the transmitter 2 and the receiver.

[0056] In a preferred embodiment of the invention, the transmitter 2 can be connected to a control circuit for two primary right and left flashing lights of the vehicle, and said at least one secondary signal light 3d, 3g comprises two secondary right and left flashing lights 3d, 3g. The verification means then detect when a secondary flashing light is operating or not according to its power supply.

[0057] Furthermore, the transmitter 2 can also be connected to a control circuit for at least one primary auxiliary signal light of the vehicle. The signaling device 1 may also include at least one secondary auxiliary signal light 4, said at least one primary and secondary auxiliary signal light being taken individually or in combination from among a brake light indicating braking, a position light, a fog light or a hazard warning light.

[0058] Generally, all the primary signal lights fitted to the vehicle can be linked to the signaling device 1 worn on the user's back. This can all be done using the same transmitter 2 and the same receiver, which combine the pairings of the primary and secondary signal lights.

[0059] At the center of the signaling device 1 is a pairing button with one or more visual indicators that flash to signal that the receiver is in "Search Mode" for the transmitter 2 mounted in the vehicle. By pressing the vehicle's brake for two seconds, the secondary Stop signal light of the signaling device 1 according to the present invention illuminates. The transmitter 2 and the receiver are then paired.

[0060] The signaling device 1 according to the present invention, including its receiver and transmitter 2, are factory-paired. The user pairs the transmitter and receiver by pressing a button located under the lighting unit near a USB Type-C connector. If the button is pressed for less than one second and the vehicle is off, a hazard mode is activated or deactivated. If the button is pressed for between two and four seconds, a pairing mode is activated; if the vehicle is braking or not braking, a deep sleep mode is activated; if the button is pressed for more than four seconds, a demonstration mode is activated. The fog light function can be provided by one or two red LEDs located in the center of the signaling device 1.

[0061] The secondary brake light, advantageously LED, can be used as a position light. This is achieved by using two different light intensities, with the secondary brake light being brighter than the secondary position light. This function can be activated manually or when ambient light is low, for example, at dusk, or when the signaling device 1 according to the present invention is connected to the vehicle's battery via the magnetically connected cable. This provides improved visibility of the secondary signal lights.

[0062] In the event of emergency braking, both turn signals (3d, 3g) may illuminate to activate "hazard" mode, and an audible warning may sound to alert the vehicle operator. As soon as the operator activates the turn signals again, the "hazard" mode deactivates. This has the advantage of reducing the time it takes to signal an emergency stop in case of danger.

[0063] As can be seen at the figure 3 A transmitter 2, advantageously in association with a miniaturized rechargeable battery or accumulator independent of the transmitter 2, can be controlled in operating or standby positions by a removable push button 16. The positioning of the push button 16 may differ from that shown in the figure 3 .

[0064] Transmitter 2 can be placed inside the vehicle or even remotely, for example in a pocket of the user's clothing. Transmitter 2's function can be activated via a mobile phone with the appropriate application.

[0065] Transmitter 2 may have its own power source via rechargeable batteries or accumulators. Transmitter 2 may be recharged by induction, via a micro USB cable, or via a cable directly connected to the battery. When the battery(ies) of transmitter 2, receiver, or rechargeable device 1 are low, the signaling device 1 according to the present invention is notified by a visual and / or audible signal.

[0066] Transmitter 2 is thus 100% waterproof. The signaling device 1 according to the present invention and transmitter 2 can be recharged using an induction system. By placing it on the base of the induction system provided for this purpose, recharging is carried out without any connection between these two elements.

[0067] Transmitter 2 may have a current detector in the control circuit(s) associated with the primary signal(s), or the activation information for a primary signal may be transmitted via a wired connection to transmitter 2. The diagnostic port does not provide information regarding the activation of the brake light, position light, fog light, right turn signal, left turn signal, or hazard warning light. The connection between transmitter 2 and the receiver is made via radio frequency waves or Wi-Fi using a suitable protocol, such as Bluetooth®, but this is not limited to these protocols.

[0068] For example, but not limited to, current detectors detect active signals in order to send the brake light and / or turn signal activation information to signaling device 1. This provides a quick connection without any specific adaptation that could void the manufacturer's warranty.

[0069] As shown in the figure 3 For the various signaling devices, such as the 3D and 3G turn signals, the brake light, and the position lights, transmitter 2 can be equipped with four current detectors, one for each signal. Transmitter 2 is capable of detecting the current flowing in a cable of the signaling system when it is powered. When the vehicle operator presses the brake and / or uses the turn signals, the signaling devices, advantageously LEDs, brake lights, and / or primary turn signals are powered. Transmitter 2 detects this and sends the appropriate signal to the receiver. Regarding the fog light, it is activated by a three-position switch. In position 1, the position light and fog light are deactivated. In position 2, the position light is activated alone. In position 3, both the position light and fog light are activated.

[0070] This eliminates the need for quick-connect terminals or soldering, avoiding any contact with the vehicle's signaling system's power cables. Such a connection is quick and tool-free, requiring no specific modifications to the vehicle that could void the manufacturer's warranty.

[0071] Advantageously, said at least one secondary signal light 3d, 3g is in the form of a lamp or light-emitting diodes whose luminous intensity varies according to the ambient light. Light-emitting diodes are visible at the figure 4 on a printed circuit board 15 housing the electronic means and the means for interpreting the accelerometer measurements.

[0072] It is possible to adjust the intensity of the LEDs according to the ambient light. This function adapts the brightness of the LEDs to the surrounding light. In broad daylight, the intensity of the LEDs is increased to ensure that the signaling device 1 according to the present invention is visible, even in direct sunlight. At night, the intensity of the LEDs is reduced to avoid dazzling following vehicles. This contributes to increased driving safety by preventing glare for vehicles near the vehicle associated with the signaling device 1, while also ensuring better energy management.

[0073] The signaling device 1 may include radar detection means for another locomotor in the vicinity of the locomotor for which the device 1 is intended, with estimation of a distance separating the other locomotor from the device 1. When this distance is less than a predetermined minimum safety distance between the two locomotors and stored in storage means provided in the electronic means, the control means of said at least one secondary signal light 3d, 3g illuminate said at least one signal light with a specific intensity and / or periodicity recognizable to signal that the predetermined minimum safety distance between the two locomotors is not respected.

[0074] The predetermined distance depends on the speed of the vehicle and the following vehicle(s), as well as the terrestrial, aerial, or maritime environment in which the vehicles are moving. This function is activated only if the vehicle is traveling at more than a predetermined speed, which also depends on the environment, and not when stationary. In this case, the main secondary signal lights of the signaling device 1 according to the present invention, advantageously three in number including the brake light and the two turn signals 3d, 3g, can illuminate and flash rapidly, for a given duration and intensely, to signal to the following vehicle that it is too close, so that the latter maintains a sufficient safety distance.

[0075] A red "I" shaped signal may also light up and flash to signal to the following vehicle that it is too close, so that it maintains a sufficient safety distance.

[0076] In all cases, the use of such a radar makes it possible to keep a following vehicle at a safe distance from the locomotion vehicle equipped with the signaling device 1 according to the present invention.

[0077] It is also possible to equip the signaling device 1 with a rear-view camera and / or a front-view camera. Thus, the signaling device 1 according to the present invention is equipped with two multidirectional cameras. The rear-view camera can be positioned on the printed circuit board 15. The operator of the vehicle equipped with the signaling device 1 can see what is happening behind the vehicle. The images can be transmitted to a dedicated screen or to a mobile phone. The rear-view camera is activated from the screen or the mobile phone. The camera can be activated while reversing or while driving.

[0078] As for the front camera, it can be positioned in a housing on a portion of the front strap 6 which passes over the front of the user's body and serves to hold the signaling device 1 on the user's back, with or without a flashing reminder.

[0079] In both cases of front or rear camera, the images can be recorded in the memory of the dedicated screen, the mobile phone or in storage means equipping the signaling device 1 by being advantageously incorporated into the printed circuit board 15 inside the device 1. A logo can identify the switch to a "Signal Recall and Statistics" application which groups the stored images, in the event that such an application is installed in the screen, the mobile phone or the device 1. Thus it is possible for the user to reverse their rolling vehicle equipped with device 1 without turning their head while having rear visibility while moving, which increases the safety of the locomotion vehicle.

[0080] By referring in particular to figures 1 And 4 à 8, a hollow hull 5 in two portions 5a, 5b which can be removably joined together can delimit an enclosed interior space housing in a watertight manner said at least one secondary signal light, the electronic means and at least one power supply 8 for the electronic means and the receiver.

[0081] To the figure 4 A printed circuit board 15, intended to be housed in the casing 5, is visible. figure 5 A first portion 5a of the shell forming a lid is shown. At the figure 6 A second portion 5b of the shell forming a receptacle is shown. figure 7 shows a shell 5 assembled on a shell support 10 intended to be applied against the back of the user of the locomotion device and the figure 8 The image shows the shell support 10 shown in isolation. For better visibility from the outside, there may be reflective strips around the perimeter of the shell 5.

[0082] As shown in the figure 1 For its attachment to the user's back, the signaling device 1 may include at least one adjustable strap 6 passing through the shell 5 and wrapping around the user's body, featuring quick-release fastening means 7m, 7f by snap-on mechanism, advantageously two straps 6 wrapping around each of the user's shoulders. The shell 5 may therefore be externally equipped with at least two adjustable straps 6 for attaching the shell 5 to the user's back.

[0083] The straps 6 can be equipped with yellow or orange LEDs to make the user visible, especially when filtering through traffic. The LEDs can be integrated into a housing that attaches to the strap, with one housing for the right strap 6 and another for the left strap 6. The LEDs on the straps 6 can be activated in two ways. One method involves a wired connection to the signaling device 1 according to the present invention. This requires electrical connections that may compromise the water resistance of the shell 5.

[0084] Alternatively, activation can be wireless, using a transmitter 2 in the signaling device 1 and a receiver on one of the straps 6. The presence of small batteries on the straps 6 is advantageous. Such illuminated straps 6 make the vehicle visible in its surroundings, for example, by making it visible to a vehicle in the rearview mirror of the vehicle in front of it.

[0085] By referring in particular to figures 5 And 6 , the shell 5 may include a first portion 5a of the shell forming a cover and a second portion 5b of the shell forming a receptacle for the electronic means and said at least one power supply 8. It is the second portion 5b of the shell which is intended to be opposite the back of the user.

[0086] The first 5a and second portions 5b of hull 5 can fit into each other with the first portion 5a of hull presenting an opposite face furthest from the second portion 5b in the fitted position of the first 5a and second portions 5b of hull 5.

[0087] The signal light(s), in the form of lamps or light-emitting diodes, are inside the shell 5. Only one light-emitting diode is referenced 18 in the figure 4 but this reference is valid for all light-emitting diodes found on the printed circuit board 15.

[0088] As shown in the figure 4 , the first portion 5a of the shell forming the cover may have transparent areas 9 opposite the one or each secondary signal light housed inside the shell 5.

[0089] As shown in the figure 5 , the second portion 5b of the hull forming a receptacle can receive the electronic equipment and the battery referenced 8 to the figure 2 The second portion 5b of the shell may include stops 8a at least partially defining the battery enclosure and lugs 15a for supporting the printed circuit board, the battery 8 and the printed circuit board 15 not being visible at the figure 5 but being at the figure 2 .

[0090] To the figure 5 A 20-pin inlet port, for example for charging the battery, is visible in the second 5b section of the hull. A protective cap, visible at figures 9 And 11Under reference 19, surrounds this inlet port 20 by joining the first and second hull sections. The second hull section 5b includes a half-compartment 14 intended to be completed by a half-compartment supported by the first hull section to form a semi-closed assembly and ensure a seal at this inlet port 20. Thanks to the shape of the protective cap, the multifunction button can be used.

[0091] The use of a flexible 15-pin printed circuit board as shown in the figure 4 allows for the manufacture of a flexible shell 5, which provides the user with a better feel when wearing the shell 5 combined with ease of storage.

[0092] The first 5a and second 5b sections of the shell 5 can be advantageously 100% recyclable. The fact that the first 5a and second 5b sections of the shell 5 are nested one inside the other provides easy loading and ensures the shell 5 is 100% watertight. This is particularly relevant when the battery(ies) inside the shell 5 are charged inductively, since in this case, there is no need for a charging port on the edge of the shell 5.

[0093] The housing 5 can be molded as a single piece without any external openings, with the secondary signal(s) positioned inside the housing. The first section 5a of the housing, forming the lid, is injection-molded from a transparent, light orange material, with the addition of a mask 5c over the areas where the secondary signal(s) must be visible. The second section 5b of the housing, forming the receptacle, can be injection-molded from an opaque material in various colors. Therefore, there is no need to glue windows to allow the secondary signal beams to exit the housing, thus ensuring a better seal. The housing is molded using a relatively simple mold design.

[0094] The transparent areas 9 through which the light beams of the signal light(s) pass are convex so that the light beams are always visible, regardless of the pilot's angle of inclination, whether they are in a more or less upright position or lying down on the vehicle. This makes the light signals visible even if the signaling device 1 according to the present invention is at 90°.

[0095] In a first embodiment of the attachment of the shell 5 to the user's back, the second portion 5b of the shell is intended to rest against a portion of the user's back. In this case, the second portion 5b of the shell, or even the entire shell 5 with its first 5a and second portions 5b, may have four recesses 11 paired in two pairs for the passage of a portion of the strap 6 of at least two adjustable straps 6. This is shown in part in the figure 10 .

[0096] In a second form of realization shown in particular to figures 7 et 8 A shell support 10 is interposed between the second portion and the user's back. The shell support 10 may have a bearing surface intended to rest against a portion of the user's back. In this second embodiment, on a face of the shell support 10 opposite the face conforming to a portion of the back, quick-release fastening means 13 of the self-adhesive strip type are provided on opposite portions of the shell support 10 and the second shell portion 5b.

[0097] As can be seen at the figure 7 , the shell support 10 may protrude from the shell 5 when the shell 5 is superimposed on the shell support 10 by at least four arms 11a, each arm having a recess 11 for passage for a portion of strap 6 of one of said at least two adjustable straps 6, the arms 11a and their recess 11 being laterally paired in pairs.

[0098] To figures 9 And 11 A part 19 is shown, which houses a portion of the first and second hull sections. This part 19 can serve to reinforce the connection between the first and second hull sections and also to form a watertight entrance for a communication port.

[0099] The protective cap 19 has a U-shaped cross-section with a first arm 19a of the U applied against a portion of the first shell section and a second arm 19b of the U applied against a portion of the second shell section, the bottom of the U being applied against the edge of the shell. The protective cap 19 also includes a passage allowing connection with the electronic components integrated into the second shell section, which forms a receptacle. The protective cap 19 also allows the use of the multifunction push button. figure 11 , it shows an inlet 21 in the shell by this protective cap 19, inlet 21 which can be closed.

[0100] By referring in particular to the figure 1 Although the user is not shown in this figure, each strap 6 can be adjusted to be intended to go around a respective shoulder of the user by passing under one of the user's arms.

[0101] There figure 10 This shows a second portion of the shell 5b with the cutouts, therefore there is no shell support interposed between the second portion of the shell and the user's back. However, what follows is valid for the embodiment showing a shell support.

[0102] For both embodiments with or without hull support 10, each passage recess 11, either on the second hull 5 or on the hull support 10, may have a median stud 12. The median stud 12 may extend in the middle and along the length of the recess 11, being in the form of a rectangular parallelepiped having a longitudinal rounded face 12a of lesser width.

[0103] A portion of each strap 6 can go around the median stud 12 around the rounded face 12a leaving the opposite longitudinal face of lesser width free for each of the two recesses 11 associated with it, each strap 6 having two free ends carrying respectively a male or female snap-on means.

[0104] With particular reference to the figure 1 Each strap 6 may have an intermediate strap section 6 oriented towards the other strap 6 at the level of the snap-on means intended to be located at the user's chest. The two intermediate strap sections 6 may have a free end with complementary male and female snap-on means respectively for joining them.

[0105] It should be noted that the signaling device 1 can also be integrated into a jacket on the user's back, for example in a closed, transparent pocket, by means of an adhesive strip, or attached by two adjustable straps 6 to the airbag vest. The vest can be an inflatable vest in case of an accident, also called an airbag trigger vest, also known by its English name, Air-Bag Vest.

[0106] The signaling device 1 according to the invention, particularly in its electronic means in the form of a printed circuit board 15, may incorporate one or more systems fulfilling one or more of the following functions: a local navigation and geopositioning function, an interconnection function with a mobile phone having downloaded a suitable application, an electronic key function locking the start of the locomotion machine when the signaling device 1 is away from a predetermined distance from the locomotion machine or unlocking it when closer to the locomotion machine than the predetermined distance.

[0107] A Bluetooth® or wired pairing can connect the signaling device 1 according to the invention to a mobile phone, tablet, or laptop or desktop computer. This allows the transmitter 2 of device 1 to record information such as, for example, the user's first and last name, date of birth, blood type, photograph, date of issue of their license, and, where applicable, the registration number of the vehicle, its serial number, photographs of the vehicle, and its maintenance log.

[0108] The application allows pairing, on the one hand, the transmitter 2, connected to the vehicle, and the signaling device 1 according to the present invention, worn by the user, with, on the other hand, a mobile phone. For example, the user can create a profile on this application. Before traveling, they can define their route. Once the route is validated, people who log in and have access to the user's profile can follow their journey live. Upon arrival at their destination, the user reports it on the application. In case of a fall or disappearance, the user can be contacted, and if they do not answer, they can be geolocated using their navigation system so that emergency services can intervene as quickly as possible. Even if the mobile phone battery is dead, the user is still tracked in real time.

[0109] Thanks to this function, the user wearing signaling device 1 can view data and activated signals from signaling device 1 on their mobile phone screen. The application on the mobile phone collects and provides statistical data. This allows for better energy management and improved visibility of stored data.

[0110] Furthermore, transmitter 2 can be connected to the starting system of the locomotor. The signaling device 1 according to the present invention must be at a maximum distance of two meters from transmitter 2 to initiate the starting of the locomotor. If the signaling device 1 according to the present invention is more than 2 meters from transmitter 2, the locomotor may stop instantly and an alarm may be triggered.

[0111] This function is similar to that of an electronic key or hands-free kit for unlocking and starting a motor vehicle. This provides protection against theft.

[0112] In the event of a fall or accident, the signaling device 1 according to the present invention can trigger a specific audible signal to alert people located a safe distance from the accident. If the fall or accident occurs in a deserted area, this will allow emergency responders to find the user wearing the device 1 more quickly. This is particularly relevant, for example, in an avalanche involving a snowmobile. The rider can manually stop the sound. If the rider is unconscious, the signaling device 1 according to the present invention sends an emergency signal to rescue services. The rider can also manually send the emergency signal to rescue services.

[0113] It is possible to dedicate a second battery solely to this function, or to use a magnetic connection cable to connect to the vehicle's battery. This saves time in locating the pilot.

[0114] Thanks to the navigation and local geopositioning system chip advantageously integrated into transmitter 2, in case of theft, the vehicle can be found wherever it is.

[0115] The invention finally relates to an assembly of a locomotion device and a signaling device 1 worn on the back of a user of the locomotion device, characterized in that the signaling device 1 is as previously described, an emitter 2 of the device 1 being housed in the locomotion device or located near the locomotion device.
