    [0001] Head-up projection device for motorcycle helmet. BACKGROUND OF THE INVENTION The head-up projection devices are widely developed in the military field and tend to become democratized in the civilian field. These devices find many applications in cars, everyday life or logistics companies. The field of bikers, however, meets specific requirements. Thus, the proposed device must meet these requirements so that it does not fall into the domain of inappropriate technology gadget.
    [0002] A motorcyclist chooses his helmet according to many parameters such as the morphology of his head, the comfort procured, the soundproofing or the price. US Patent 20130305437 filed by Skully (registered trademark) provides an integral helmet in which is integrated a head-up projection technology. This approach severely limits the number of bikers targeted. The latter must not only buy a helmet that is imposed on them in addition to the head-up projection system. The electronics and batteries built into the helmet make it heavier and balanced, the helmet will increase the musculoskeletal disorders of the user thus reducing the mobility of his head. This fact seriously affects his safety. In addition the costs of manufacturing and therefore sales of the helmet will be high: to offset the weight of electronic components, composite materials lighter and expensive will be used. All motorcycle helmets are subject to rigorous safety standards, which must be certified by the competent authorities. The company NUVIZ (registered trademark) offers an adaptable system that attaches to the outside of the helmet on the chin strap. The disadvantage is that this projection system can be fixed only on the integral helmets, having a chin strap. Jet helmets dominate the market for scooter users. In addition, the projection system being outside the helmet, the user is dependent on the weather, the projection system is inoperative in the rain. The US20130222213 patent for its own internal integration without however specify the type of mechanical device used and the function it must fulfill. Technologies for adapting an optical device to a headset via a mechanical system are numerous. In addition this system must allow to respect the box of the eye imposed by the projection lens. Regarding the display of information, US Patent 20130305437 A1 proposes a technique for seeing backward ("a look down micro display" in English). In order for the rider to anticipate dangerous situations as much as possible, he must look away. In addition, the display superimposed on the user's field of vision must not interfere with the control of mirrors. US Patent 7961117 B1 proposes to associate the position of the projected image with the displacement of the eye. It would be better to associate the projected information with the route followed in the manner of traditional traffic signs. In addition, the net field of vision of any driver decreases with speed. It is therefore necessary to adapt the display of the information so that it remains legible and does not interfere with the conduct or search for visual traffic information. Motorcycle mirrors offer a limited field of vision and blind spots persist. Without a head-up device, the rider must always turn his head to check that there are no dangers in blind spots. The patent filed by Skully (registered trademark) WO 2013176997 A1 makes it possible to film these blind spots using a wide-angle camera fixed to the back of the helmet. This video is transmitted in real time in the direct field of vision of the rider thanks to the projection module. This innovation has the disadvantage of having a mobile mirror. So when the rider turns his head at intersections, blind spots appear and disappear along with the movement of the head. In addition, continual camera movement must be particularly destabilizing for the rider. The detection of accidents and the automatic call for help is a major challenge when it comes to reducing the intervention time of rescue to increase the chances of survival of the wounded. Peugeot (trademark) proposes such a system through the patents WO 2009083698 A1 and A2. The disadvantage is that this system is integrated into the car and offered as an option for purchase. Today smartphones are widespread and have sensors accurate enough to allow accident detection. US Patent 2013/0138715 A1 proposes a method for detecting accidents on a portable device but requiring communication with a server to be validated. This information processing can be done directly on the portable device. US Patent 2013/0069802 A1 proposes an equivalent system without taking into account the state of the pavement, greatly affecting the acceleration values measured. It also does not combine the use of the magnetometer with the accelerometer to measure the current angle of the vehicle relative to the orientation of the mobile device. This patent limits the reliability of accident detection and restricts its use to cars. OBJECT OF THE INVENTION The object of the invention is to improve the safety and comfort of riders through a head-up projection device intelligently integrated into the system consisting of the motorcycle, the driver and his helmet. The invention thus relates to a head-up projection device which is fixed inside a motorcycle helmet comprising a visor, characterized in that it comprises: means for holding said device in the helmet in the form of a clip hung on the helmet shell in a region close to the eye; at least one transparent optical element placed between the visor of the helmet and the eyes; mechanical means for positioning optical means in front of the eye between the holding system and the optical device. said holding means may be composed of magnets at the opposite poles taking the visor of the motorcycle helmet in a vice and / or a piston inserted into the face opening of the helmet, between the head and the visor. Said mechanical means may comprise two ball joints in tight fit. Wireless connection means with a telecommunication terminal may be provided.
    [0003] Wireless connection means with a camera attached to the rear of the motorcycle facing the road can also be provided, including reproducing a virtual rearview mirror immobile through said optical means. The projection device may comprise and / or cooperate with an electronic box in wired or non-wired connection with said optical means.
    [0004] It may include a gyroscope located inside or outside the helmet. The device may comprise and / or cooperate with processing means, able to detect a situation and / or a risk of accident. In this case, said processing means may be implemented at least partly in a telecommunication terminal.
    [0005] Said processing means may in particular comprise at least one of the following means: means for reading at least one acceleration value; calibration means, as a function of at least one reference acceleration value obtained during a calibration run; alert generation means, based on a comparison of the read and reference accelerations; means of transmitting an alert, which may include the GPS position and / or the blood group of the driver; means for obtaining and analyzing the gyroscopic orientation; motion detection means; means for determining the speed, for example from GPS data, means of adaptation of the net field of view according to this speed. means of moving projected images to stay in a clear field of view; means for reading and / or calculating a GPS heading; means of recovery the orientation of the head thanks to a gyroscope located on the helmet; roll determination means; means of translation and / or rotation of the projected images.

DETAILED DESCRIPTION OF THE DRAWINGS The figures illustrate particular embodiments of the invention, given by way of non-limiting examples. Figure 1 illustrates the various elements that may be involved in the implementation of the invention. Figure 9 shows schematically these same elements, and their interactions.
    [0008] Thanks to a mechanical device 11, 18 the user will be able to integrate a head-up projection optical module 12 inside his own helmet 13. This device will make it possible to respect the box of the eye intrinsic to each optical system functioning as a lens and thus guarantee the visual comfort of the biker. As shown in Figures 2 to 4, these mechanical systems 11 are composed of two parts. The first part to fix the device to the helmet 13 without denaturing, that is to say without changes in its structure. The second 18 to precisely adjust the position of the device 11 so that it is centered on the eye of the user. The clamping device around the circumference of the opening of the helmet may for example be made by means of a clamp 21 (FIG. 2), a system 31 (FIG. 3) acting as a piston via a threaded rod or a magnet system 41 (FIG. Figure 4) attached to the visor. The adjustment device 18 can compensate for a translation and three rotations of the optical module by means of two ball joints in a tight fit. Thus the rider can use the head-mounted projection device in rainy weather.
    [0009] The control electronics of the optical module, the power supply and communication with the other peripherals can be eccentric in a housing 14 that the user can easily fit for example in a pocket 15 of jacket or pants. This housing can accommodate batteries needed for power. The preferred link is wired, but a wireless link can also be considered. Thus, the heavy elements are not stored in the helmet and the latter is not modified. The projection device images of the invention substantially improves the safety of the rider through: an algorithm that refocuses information (speed or GPS 16 or rear camera 17 filming including blind spots) projected in real time depending on the speed of the bike. The user always perceives the information clearly. an algorithm which projects, as illustrated in an example in FIG. 5, the information as a function of the heading of the road and which cancels the head movements so that the projected information remains fixed with respect to the road. Always with a view to safety so as not to disturb the mirrors or a search for lateral information when the biker turns his head (intersections, cars insertion, billboards). A wide-angle camera 17 fixed at the rear of the motorcycle (filming blind spots) for displaying a fixed mirror in the direct upper field of view of the user through the optical module. This device is in wireless connection with the box. Preferably Wifi. This camera is mounted on a pivot link to compensate pitch and has a vibration damping system of the bike. The projected information such as GPS guidance, speed, accelerometer or gyroscopic values are recovered for example via the sensors of a telephone equipped with processing means ("smartphone") 16. As detailed by the algorithm of FIG. , the field of view (illustrated in Figure 5) can be adapted according to the speed and preferences of the user. The position and / or the content of the projected image can also be adapted, for example according to the algorithm of FIG. 7.
    [0010] According to another aspect, illustrated by the algorithm of FIG. 8, the device of the invention makes it possible to detect an accident situation. In an accident characterized by a shock or excessive inclination of the motorcycle (greater than 50 degrees), a distress call can be issued to warn the rescue in case of inactivity of the rider. The shock will be recorded by the accelerometer previously calibrated by the user according to its type of vehicle. The angle relative to the current orientation of the Smartphone will be recorded by the set of accelerometer + magnetometer. Calibration and specific implementation of these sensors in the embedded algorithm presented makes reliable accident detection and consider this application for motorcycle, car, skiing or cycling.
    [0011] The distress call will communicate the GPS coordinates of the accident and if applicable information about the rider, such as blood type. The HMI is an application for Smartphone allowing for example to record the numbers to prevent in case of accident, its blood type, to define its route or the different modes of viewing the projected images. The Smartphone and the case are connected wireless type wifi or Bluetooth. Some aspects of implementation are recalled below: 1 the user may for example opt for mechanical systems FIG 2, FIG 3 or FIG 4 depending on his helmet. 2 The housing can for example be easily housed in a pocket or will be attached to the outside of the helmet using an adhesive. 3 The rear camera filming blind spots on the motorcycle will for example be mounted on a mechanical system absorbing the vibrations of the bike and compensating the pitch of the bike (via a pivot connection) to optimize the viewing angle. An adhesive is used to fix this camera to the bike. A camera can also be placed at the front of the bike on the same principle to provide evidence in case of accident. 4 An optical / electrical interface allows the transfer of images to the projection device. This part may be equipped with a 3-axis accelerometer to detect the head movements of the user. This interface is also mechanical: female part of the self-locking ball joint. 5 Double self-locking ball joint on the same axis. By self-locking ball we mean a tight fit or recourse to the rubbers so that the ball remains in position, supports the weight of the optical module and the force exerted by the wind on the module when the user rolls visor open. This double ball joint makes it possible to compensate for all rotations and small translations in order to position the optical module in the best position in front of the eye. This set is preferably made of aluminum, plastic or composite material. 6 clamp coming to grip the rigid part of the helmet, is fixed on the hull. The clamp receives the male part of the second ball joint. This clamp can be positioned all around the opening of the helmet according to the wishes of the user. The clamp makes it possible to adjust in translation and hold in position. Preferably stainless steel forceps but can be made of plastic or monolithic carbon. 7 other holding system in position is based on the principle of the cylinder. The cylinder receives the male part of the second ball joint. Realized using a threaded rod or a spring-loaded or compressed air-powered device. Another position-holding system uses two magnets with opposite magnetic poles that clamp the visor of the helmet. One of them receives the male part of the 2nd patella. Another maintenance solution is to consider the current mechanical system without the magnetized portion being fixed to the outside of the visor.
    [0012] The other part acts as a classic adhesive. This piece is made of plastic preferably or aluminum. 9 blurred area not interpreted by the brain at 130 km / h and example projection of GPS information and speed. The user will be able to set the desired speed interval in which the information display will not change. This is a question of the ratio of visual comfort / display adapted to the driving of the user. The invention therefore also relates to a method of detecting accidents on a telecommunications terminal comprising at least some of the following steps: - Reading the acceleration values of a telecommunication terminal - Summing the accelerations read on the three axes in ultimate value. G = I GX I + I GY I + I GZ I - Record the acceleration values during a usual trip, analyze the signal and extract the maximum acceleration value Gmax to define a minimum non-trip value. This calibration step is performed once.
    [0013] Compare G with Gmax taking into account the accuracy of the sensors. If G> Gmax, the emergency services are alerted, the GPS position and / or the blood type of the driver are transmitted. The method may also comprise, alternatively or in combination, at least some of the following steps: Record the gyroscopic orientation of said terminal after a deltaT time. Extract Initial Roll Ri Compare the current gyro orientation (Real Time Terminal Roll (R)) with Ri. If R> Ri + 50 or R <Ri-50 the emergency services are alerted, the GPS position and / or the blood group of the driver are transmitted. The method may further include at least some of the following steps: Read the speed (transmitted by the GPS signal) / accelerometer after 30s if one or more of the aforementioned tests are positive. The emergency call is issued only if the speed is zero or if the accelerometer does not vary (so no movements). The invention further relates to a method of projecting images comprising at least some of the following steps: Read the speed transmitted by GPS in real time. Calculate the law of narrowing of the net field of vision according to this speed. To translate the projected images to stay in the net field of vision according to this law without hindering the central field of vision. This method can also include at least some of the following steps: Read the current GPS heading when the speed is different from 0 or calculate the course to follow according to "webservices". Retrieve the orientation of the head thanks to the gyroscope located on the helmet Compare the two previous data and translate the image on the opposite side Recover the roll R on the communication terminal Apply a rotation of the images of -R.30
