[0027] The aspects of the disclosed embodiments will be presented in more detail in a preferable embodiment and with reference to the enclosed drawings where:

[0028] FIG. 1 shows a view of a designed appliance on the user's body, in an intermediate phase of opening.

[0029] FIG. 2 shows a view of a designed appliance on the user's body.

[0030] FIG. 3 shows a designed appliance on the user's body at the time of complete opening.

[0031] FIG. 4 shows operation of a system in the case of a collision of a motorcyclist with an obstacle.

DETAILED DESCRIPTION

[0032] A device according to a preferable embodiment is presented in detail in FIGS. 1 and 2. The device is suitable to be worn by the user, it comprises a fixing element 1 for fixing the device on the user, the fixing element 1 comprising packs 4. Within the packs 4 there are envelopes 2 intended to be filled with gas, connected to the fixing element, the envelopes 2 being additionally connected to sleeves 3, and all the envelopes 2 define one volume.

[0033] FIG. 2 shows in turn a protective device in a folded state when the user is not at risk and no exceeded preset values are detected. The envelopes 2 are within packs 4. The device also comprises a cylinder with pressurized gas, comprising a valve (not shown in any of the figures of the drawing). Preferably, the cylinder with pressurized gas is positioned in one of the packs 4. The outlet of the valve is connected to the envelopes 2. A measuring device (not shown in any of the figures of the drawing) for registration of the displacement parameters of the user is coupled with a valve and comprises also a set of measuring sensors (not shown in any of the figures of the drawing).

[0034] The valve is suitable to fill the envelopes 2 with gas automatically at the time when the measuring device exceeds threshold values of the displacement parameters of the user.

[0035] The envelopes 2, upon inflation, enclose the user so that they protect the entire user's body. It should be understood that inflated envelopes 2 define a volume that is capable to protect the user against hitting a flat or not pronouncedly protruding element of the environment or other vehicles.

[0036] Preferably, envelopes 2 are connected to the fixing element in a permanent manner and as a result the envelopes 2 are permanently fixed with the fixing element 1, and so prevent the envelopes 2 from detachment during an abrupt change in speed. This provides a safe and durable protection regardless of abrupt changes in speed and fall caused by e.g. throwing out from a motorcycle.

[0037] Protective device comprises at least one set of measuring sensors in a form of a built-in accelerometer assembly, and the set of sensors preferably comprises GPS and/or GSM.

[0038] Release of gas from the cylinder is effected upon receipt of a signal from the set of measuring sensors about abrupt changes in acceleration of the protected human. Upon activation of the system, the shields filled with gas are enclosed by belts so that they are pressed against each other and against the human body to define a compact structure.

[0039] The measuring device is suitable to register the horizontal speed, vertical speed and time periods during which changes in speed occur. When anyone of these parameters exceeds threshold values, the device is automatically activated and the envelopes 2 are filled with gas to define a shield for the user's body as shown in FIG. 3.

[0040] The fixing element 1 preferably is made in a form of a harness embodied as belts connected to each other. Nevertheless, this element may have any other form known to a person skilled in the art with a knowledge on how additional equipment should be mounted on the user. The fixing element 1 may have a form of e.g. a vest, suspenders, etc.

[0041] The packs 4 arranged in a belt around the hips comprise from one to fifty envelopes 2 that upon inflation protect hips, body and head of a human, and the packs 4 arranged in the remaining part of the fixing element 1 comprise from one to fifty envelopes 2 that upon inflation protect hips and legs of a human.

[0042] The envelopes 2 and sleeves 3 define one volume and this causes that the gas released from the valve of the cylinder into one envelope 2 concurrently fills all the envelopes 2 and passes via the sleeves 3 to the adjacent envelopes 2.

[0043] The method of operation of the device is shown in FIG. 4 and it comprises the following steps:

[0044] a. detecting, by a set of measuring sensors, an abrupt change in anyone of acceleration parameters, [0045] b. opening of the valve of a cylinder with pressurized gas, upon receipt of a signal from the set of measuring sensors, [0046] c. filling the envelopes 2 with gas so that the envelopes 2 protect the entire user's body, said step being visible in FIG. 4.

[0047] Preferably, following step c. a step d. is performed consisting on establishing the position of the location where the event has occurred and transmitting information with coordinates to an emergency centre.
