Description

The invention relates to universal technical means for providing an integrated security system for training beginners and experienced athletes in new conditions in traumatic sports, such as, for example, skiing, diving, parachuting (ground training), figure skating, and in traumatic forms of art, for example in circus.

Known protective clothing for a motorcyclist containing an airbag in the form of tight bags folded like a pleat and fastened in a strip on protective clothing, each of the tight bags is equipped with a pyrotechnic gas generator controlled by an electronic or sensor device (German patent No. DE 10316766, A1, priority date 04/10/2003, publication date 10/28/2004, GENIMA INNOVATIONS MARKETING G, DE).

A disadvantage of the known analogue is the limited area of use, mainly for protection against shock when falling from a motor vehicle.

As a prototype, a device for protection against injuries in the fall was adopted, including shock-absorbing elements in the form of airbags fixed to the human body, mainly in the region of the waist and hips, with the possibility of rearrangement along the waist and in height relative to the waist, the airbags are connected to the electrically operated a system comprising an angular velocity sensor, a microcontroller, an actuator and an electrical power source, while the output of the angular velocity sensor is connected to the input m the microcontroller, the output of which is connected to the control input of the actuating element, the power supply is connected to the angular velocity sensor, the microcontroller and the actuating element, made in the form of an instantaneous gas generator with an electrically operated pyro cartridge and a valve associated with airbags (RF patent No. 533110, U1, priority date 12/07/2005, publication date 05/10/2006, authors Firsaev Yu.F. and Bykov Yu.Ya., RU, prototype).

The disadvantage of the prototype is the limited scope and low efficiency, since the device is completely on the human body, protects only parts of the body from impact and can not be used in such traumatic sports as skiing, diving, parachuting (ground training ), figure skating.

The objective of the invention is the creation of a universal athlete protection system by increasing the effectiveness of the protective function against impact on a solid surface or water.

To solve the problem in the athlete’s protective system, including the executive part located on the human body, containing shock-absorbing elements for protection against injuries, actuated during a critical fall using the control system, according to the invention, the control system is made on the basis of radio navigation means, as external, and partially located on the human body (for navigation purposes, in particular, radar can be used), and with the possibility of determining the relative position of of the human body, limbs and trunk, while miniature resonant reflectors of radio waves with resonances at different frequencies are installed on the surface of the human body near large joints, or miniature active transponders to sounding radio signals, or beacons emitting signals of different frequencies or different shapes, external radio navigation the means comprise a system of active or passive radars, a control signal generator connected to its transmitting antenna for transmitting control signals to the real part, and a computer connected with them, while the radar system contains at least a system of at least four receiving antennas that are not in the same plane, connected to receiving devices, each of which contains channels corresponding to the resonance frequencies of the reflectors or signals emitted by active transponders or beacons, the channel outputs being connected to a computer.

According to the invention, the transmitting and receiving antennas of the radars can be fully or partially combined, which reduces the number of antennas and accordingly facilitates and reduces the cost of the design.

According to the invention, the athlete’s protective system when using resonant reflectors of radio waves or active transponders in it further comprises a probe signal generating device connected to its transmitting antenna.

According to the invention, myostimulants attached to the muscles of an athlete can be used as shock-softening elements.

According to the invention, airbags or a two-layer airtight suit inflated by means of instant gas generators can be used as shock-softening elements.

The drawing shows a structural diagram of a protective system of an athlete, providing tracking of the trajectory of the athlete and the transmission of control signals to the executive part using radio navigation aids (in particular, radar for navigation).

The athlete’s protective system is universal for traumatic sports such as downhill skiing, diving, parachuting (ground training), figure skating, as well as for traumatic art such as circus, as it contains, firstly, a system of constant position tracking athlete and assessing whether this position is safe, prior to falling or getting injured; secondly, the system of soft safe fall due to the presence on the athlete of shock-softening elements in the form of airbags or muscle stimulators that automatically work at the moment when the position of the athlete becomes unstable or traumatic.

The athlete's protective system includes an actuator located on the human body with shock-absorbing elements to protect against injuries and a control system that actuates the actuator during a critical fall. The control system is automatic based on radio navigation aids (in particular, radar for navigation), both external and partially located on the human body, and contains elements placed on the athlete’s body to determine the relative position of the parts of the human body, limbs, trunk and Constantly tracking the position of the athlete in three-dimensional space. As such elements, resonant reflectors of radio waves with resonances at different frequencies, or miniature active transponders to probing radio signals, or beacons emitting signals of different frequencies or different shapes, mounted on the athlete’s body over the entire height, preferably on each large joint or nearby, can be used ( conditionally not shown). External radio navigation aids include a radar system containing, for example, four receiving antennas 1, 2, 3 and 4, not all located in the same plane. Receiving antennas are connected to receiving devices 5, 6, 7, 8, each of which contains channels corresponding to the resonant frequencies of the reflectors or the signals emitted by active transponders or beacons. Moreover, the number of channels corresponds to the number of resonant reflectors, active transponders, or beacons installed on the human body. The outputs of the channels of the receiving devices are connected to a computer 9, which processes the signals and determines the three-dimensional coordinates of each reflector, active transponder, or beacon. A control signal generator 10 is connected to the computer 9, having its own transmitting antenna 11 for transmitting control signals from the computer 9 through the receiver 12 to the actuating part 13.

The athlete’s protective system, when using resonant reflectors of radio waves or active transponders, additionally contains a probe signal generator 14 connected via a transmitter 15 to its transmitting antenna 16.

For the functioning of radio navigation aids around the training venue, or along the ski slope, a system of radars must be installed connected to a computer whose programs use objects (matrices, arrays, etc.) that are functionally similar to objects of programs that draw human movements, in terms of description human poses. On the ski slopes several radar systems are installed depending on the length of the slopes.

The athlete's defense system is used as follows. When training novice athletes, as well as experienced athletes on new tracks or other sports facilities, platforms, radars installed around the training venue or along the track, monitor the position of the athlete’s body by the resonant reflectors installed in his suit, active responders or beacons. Each resonant reflector, active transponder or beacon is recognized respectively by its resonant frequency or radiated signal. Information on the relative positions of resonant reflectors, active transponders or beacons, and therefore joints, in three-dimensional space, obtained by at least four receiving antennas 1, 2, 3 and 4, connected to their receivers 5, 6, 7 and 8, is monitored computer 9 using a mathematical description of a person’s position functionally similar to that used, for example, in Poser programs and the like. At the beginning of the athlete’s fall, computer 9, by the position of the reflectors, active transponders or beacons, corresponding to the position of the person, will determine that the situation is critical, and through the control signal generator 10, connected to its transmitting antenna 11, will send a radio signal to deploy airbags or muscle stimulators. In this case, this radio signal through the antenna of the control signals 11 will go to the receiver of the control signals 12, which, in turn, will provide an electric signal to the actuating part 13 for triggering, for example, instantaneous gas generators or muscle stimulators. The use of these or other shock-absorbing elements depends primarily on the sport and the conditions in which the training takes place. In the case of training, for example, a skier, it is advisable to use a two-layer inflated suit, in which there are instantaneous gas generators, when triggered, the suit is inflated so much that it takes on the shape of a ball inside which the athlete is located. Moreover, not a single part of the athlete’s body touches the outer layer. In the case of a jumper training in water, the control signal generator 10 connected to its transmitting antenna 11 will send a signal to the coordinated response of the muscle stimulators calculated by computer 9, which will turn the athlete's limbs in such a way as to make it safe to enter the water.

The advantage of the claimed athlete’s protective system compared to the prototype is to obtain a higher technical result, which consists in the automatic response of the system and its application in those sports where the angular velocity sensor is not enough to determine the position preceding a critical fall, as well as to create a universal an athlete’s protection system, requiring only replacement of programs for various sports or art, and in increasing the effectiveness of the protective function from hitting a hard overhnost or water.
