    Description: The present invention relates to an airbag safety device for preventing injuries to the hips, pelvis, buttocks and coccyx in the event of a fall.
    US 2015 351 666 A1 describes a movement analysis system comprising at least one orientation sensor configured to detect the movement of the torso in three dimensions over time, as well as an airbag triggered during a fall to cushion the user's body. This device is restrictive and uncomfortable insofar as a plurality of sensors is distributed over the system, including a sensor placed on the user's neck.
    US 692 0647 B2 describes a hip protection device making it possible to minimize the risk of hip rupture during a fall. This device has a system for detecting the rate and degree of change in attitude of the user, thus allowing the device to engage during a possible fall in order to inflate pockets and absorb the fall.
    The object of the present invention is to propose an airbag safety device which is not very restrictive for the user and which does not fire unexpectedly.
    According to the invention, a safety device for preventing injuries to the hips, pelvis, buttocks and coccyx by inflating an airbag suitable for a wearer comprises: a portable inflatable pocket, which can be coupled to a garment; at least one releasable gas source coupled to the pocket; a belt buckle in which are arranged a plurality of sensors making it possible to determine the angular movement and the acceleration of a wearer during a fall; a microcontroller adapted to analyze the data received by the various functional blocks to define the moment when to trigger the gas source; and means for releasing the gas from the source in the pocket according to a determination by the microcontroller that the wearer falls.
    Two of the sensors arranged in the loop are a first thermal sensor measuring the ambient temperature and a second thermal sensor measuring the body temperature of a wearer. The first and second thermal sensors are arranged to allow the airbag to be triggered in the event of a fall only when the device is worn by a wearer, in particular by measuring the temperature difference measured by the two thermal sensors, thus ensuring the presence of a carrier.
    In one embodiment, the loop has at least one pair of magnets, preferably two pairs, for locking the loop.
    In another embodiment, the loop includes a piston switch for activating the device, once the belt is closed.
    In one embodiment, the device comprises a rechargeable energy source through the loop, in particular by USB cord.
    In all embodiments, the device can include a six-axis inertial module for detecting the movements of a user, the inertial module comprising in particular an accelerometer coupled to a gyroscope.
    According to a particular embodiment, the loop has an opening arranged to let through an electric wire arranged to transmit an electric pulse given by the microcontroller to authorize a triggering of the airbag in the event of a fall.
    In one embodiment, visual and / or audio means are arranged to indicate the operating state of said device.
    Preferably, the loop comprises (A) a first cylindrical deformed part comprising a helical groove extending from one end of the first loop part, the groove being slightly curved with a notch at its second end, and ( B) a second part comprising a protuberance arranged to slide in said groove and come to engage in said notch. Each part of the loop has a magnet arranged to secure the first and second part of the loop, the two said loop parts being detachable from one another by the angular displacement, in particular of at least one eighth of a turn d 'a first part of the loop relative to the other part of the loop then by the sliding of the protuberance in the groove until its total extraction.
    Such a loop, whether or not provided with electronics, can easily be arranged on other forms of belts in particular to facilitate the opening and closing of the loop.
    In one embodiment, the loop is in particular formed of two assemblable parts, a first part in the form of a rectangular box containing the electronics and a second part also rectangular, these two parts together comprising a cylindrical connection body comprising a bayonet fixing device. The outer sides of said parts of this loop have openings for attaching to the ends of the belt pocket.
    To enhance the safety of the wearer, the device comprises a wireless communication module, in particular by radio link, capable of transmitting information relating to the triggering of the airbag to a person other than the wearer of said device. The communication module also makes it possible to geolocate the wearer. The device can in particular
    CH 714 947 A1 provide, thanks to a corresponding supervision system, on the one hand a state of the device which a third person, for example a doctor or a relative, can control at any time and in real time via the communication and d on the other hand, the geolocation of the carrier.
    Preferably, the communication module is a low consumption module so as to minimize its electrical consumption.
    The communication module is capable of transmitting information relating to a state of the device corresponding to the presence or not of a carrier and whether or not the airbag is triggered.
    The characteristics of the invention will appear more clearly on reading the description of an embodiment given solely by way of example, in no way limiting with reference to the schematic figures, in which:
    Fig. 1 is a schematic diagram showing an airbag safety device carried by a carrier;
    Fig. 2 is a perspective view from above of a loop of the airbag safety device;
    Fig. 3 is a perspective view from below of the airbag safety device loop;
    Fig. 4 is a side view of the airbag safety device loop;
    Fig. 5 is a perspective view of part of the loop of the airbag safety device; and
    Fig. 6 is a perspective view of another part of the airbag safety device.
    [0020] FIG. 1 shows an airbag safety device according to the invention worn by a wearer 6 so as to prevent injuries to the hips, pelvis, buttocks and coccyx by inflating an airbag suitable for the hips of a wearer 6. This device comprises a portable inflatable pocket 1 which can be coupled around a garment of the wearer 6.
    The inflatable pocket 1 carries a source 2 of releasable gas coupled to the pocket 1. The inflatable pocket 1 is carried by a belt loop 3, 4 in which are arranged a plurality of sensors for determining the angular movement and the acceleration of a carrier during a fall. The loop 3, 4 also contains a microcontroller adapted to analyze the data received by the different functional blocks to define the moment when to trigger the source 2 of gas as well as a means for releasing the gas from the source 2 to fill the bag 1 according to a determination of the microcontroller that the carrier 6 falls. The microcontroller forms the heart of the device executing the detection algorithm and manages all the other blocks. Once all the conditions have been met (seatbelt closed, person detected, correct direction of insertion), it is this component which will analyze the data from the inertial module in order to define when to trigger the airbag.
    One of the sensors arranged in part 3 of the loop is a thermal sensor 5 (fig. 3) arranged on the inner side of this part 3 in order to measure the body temperature of the wearer 6 coupled with an ambient temperature sensor arranged at inside the loop housing, and therefore not visible in the drawing, to provide a signal to authorize an activation of the airbag in the event of a fall only when the device is carried by a carrier 6. The thermal sensor 5 is a thermometer infrared to measure the temperature of a distant body, in particular to detect the human heat of the wearer 6. Coupled with the measurement of the ambient temperature, the system indicates whether the belt is well worn by a person rather than simply stored in the closed position.
    As illustrated in FIG. 5, the internal end of part 4 of the buckle comprises two magnets 7, 11 for locking the buckle and a piston contact 8 with springs for activating the device, once the belt is closed. The electronics are used to manage the switching on of the device. Piston contacts 8 with spring on each part of buckle the loop making contact on each part of buckle to detect that the buckle of the belt is closed.
    [0024] FIG. 6 illustrates a rechargeable energy source through the loop part 3, in particular by a USB cord
    9. This charges an internal battery. This block can be simplified and a simple battery charger will be present. The device according to the invention typically comprises a six-axis inertial module for detecting the movements of a user, the inertial module comprising in particular an accelerometer coupled to a gyroscope. These elements are contained in part 3 of the loop. This module makes it possible to detect in a known way the movements of the person and thus to predict the fall before the impact. The accelerometer coupled to the gyroscope can differentiate a real fall from simple vibration or normal movements of the person.
    Part 3 of the loop has an opening 21 (fig. 1) in its side, arranged to pass an electric wire 12 arranged to transmit an electrical impulse given by the microcontroller to authorize a triggering of the airbag in case fall.
    In this example, an LED 10 (fig. 2) and a buzzer not illustrated make it possible to inform the wearer of the operating state of the device, in particular by emitting a flashing of the LED 10 in the event of a malfunction then l 'emission of several beeps if the wearer has not reacted to the signals emitted by LED 10.
    The device can optionally include a hearing or light device making it possible to indicate to the user other situations than the malfunction. For example: when the activated belt is correctly worn: two
    CH 714 947 A1 sharp beeps, when the belt is worn but upside down: two low beeps; when the belt is removed, switch off the device: low beep, low battery: four quick low beeps every fifteen minutes.
    As illustrated, the loop is formed of two assemblable parts, a first part 3 in the form of a rectangular box containing the electronics (in particular the sensors as well as the microcontroller), and a second rectangular part 4 hollowed out. These two parts 3, 4, together comprise a cylindrical connection body 15 comprising a bayonet fixing device 16, that is a hollow cylindrical part 17 on one side of the part 3 which receives a solid cylindrical part 18 on one side of the part 4. The main surfaces of the parts 3, 4 are either flat, which is the case for part 3, or slightly curved, which is the case for part 4, in order to be able to press against the body of the wearer 6. The outer sides of parts 3 and 4 have elongated openings 19, 20 for attaching to the ends of the pocket 1 forming a belt.
