1. A safety device adapted to be worn by a wearer (6) for preventing injuries to the hips, the pelvis, the buttocks and the coccyx of the wearer (6) by airbag inflation, said device comprising:
a portable inflatable bag (1);
at least one source (2) of releasable gas coupled to the inflatable bag (1);
a belt buckle (3, 4) in which a plurality of sensors are arranged, for determining the angular movement and the acceleration of the wearer (6) of the safety device during a fall of the wearer;
a microcontroller adapted to analyze data received by different functional blocks in order to define a time to trigger the gas source; and
means for causing the source (2) of releasable gas to release the gas into the bag (1) according to a determination by the microcontroller that the wearer is falling;
characterized in that:
two of the sensors arranged in the belt buckle are a first thermal sensor measuring the ambient temperature and a second thermal sensor (5) measuring the body temperature of the wearer (6), the first and second thermal sensors being arranged for a deployment of the airbag in case of a fall only when the device is worn by the wearer, by measuring a temperature difference, as measured using the two thermal sensors, thus ensuring the presence of the wearer of the device and in that the device further comprises a wireless communication module, for transmitting information relating to: a state of the device corresponding to the presence or absence of the wearer; and to the deployment or non-deployment of the airbag to a person other than the wearer of said device, said means for causing the source of releasable gas to release the gas into the bag comprising an opening in said buckle, arranged to pass an electric wire (12) disposed to transmit an electrical pulse given by the microcontroller for said deployment of the airbag in case of a fall.
