Description

The invention relates to the field of safety during the operation of vehicles.

A device for fixing passengers in an armchair is known, comprising an arc covering branches of a passenger’s shoulders, a transverse element located above the passenger’s hips, and also equipped with adjustable stops on the seatback and arc branches to exclude collisions of a passenger’s face with an arc / see, for example, RF patent for invention No. 2236273, class A63G 7/00, 21/00, 2002 [1] /.

A device is also known that holds a passenger in an armchair or seat using special fixing belts with fastening means, as well as fastening straps made in the form of chest and lumbar fastening belts connected by a locking mechanism and equipped with a means of retracting the belts inoperative / cm. RF patent for utility model No. 75358, class. B60R 22/00, 2008 [2] /.

The disadvantages of the known devices is that, to some extent protecting passengers from vibration and impulse inertial influences, they absolutely do not protect the driver from attacks from passengers. This is especially true for a passenger located behind the driver’s back out of his field of vision, which in this situation represents the maximum danger to the driver.

The closest device of the same purpose to the claimed invention by the set of essential features is a means to protect the driver from attack, made in the form of a screen of solid flat material placed between the ceiling of the passenger compartment and the backs of the driver's seat and the adjacent front seat and equipped with means for attaching to the backs of the seats /cm. RF patent for utility model No. 71602, class. B60N 2/44, 2007 [3] /, and adopted as a prototype.

The disadvantages of the prototype device are the state of discomfort, isolation, limited space, feelings of anxiety, etc., reported to passengers when they are isolated from the driver by a screen, grille, etc., and most importantly, the low efficiency of protecting the driver from attack. The latter is due to the fact that the passenger, in the presence of aggressive intentions and fixing an unmasked protective device in the form of a screen, grille, etc., if there is a margin of time, develops another scheme for attacking the driver: at the time of getting out of the car, or at the time of boarding , or provoking the driver to a stop, etc., which further increases the risk of attacking the driver.

It would be advisable to create a device hidden in the passenger compartment of the vehicle from passengers that protects the driver from attacking passengers, mainly from the rear seats behind the driver’s back, easily and quickly driven by the driver immediately at the time of the attack and providing instant and simultaneous power impulse, current shocking and holding a fixing effect on the attacker, and with increasing intensity of the impact with the continuation of attack attempts.

The essence of the invention lies in the creation of an electromechanical device to protect the driver from attacking him from behind, disguised as passengers, driven by the driver immediately at the time of the attack and providing simultaneously shock, current and restraining effects on the attacker.

The technical result is an increase in the effectiveness of protecting the driver from attack, increasing comfort when traveling passengers in vehicles.

The specified technical result in the implementation of the invention is achieved by the fact that in the known means for protecting the driver from attack, made in the form of a mechanism for restricting the movement of passengers sitting behind him by the area of the rear seats, the feature is that the mechanism for restricting movements is an electromechanical device with simultaneous shock, fixing and current-damaging effects, placed under the seat behind the driver and made in the form of a twisted coil spring self-compression, fully compressed in the initial state, placed along the longitudinal axis of the car in a plane parallel to its floor at the height of the lower legs of the person, attached to the floor at the rear end and equipped with a trap for the legs orthogonal to it in the same plane of the spring in the same plane in the form of a shaped flat spring from a steel wire with turns in the form of ring hinges-grips, overlapping in its length the entire width of the rear seat, facing the entrances to the turns towards the passage between the front and rear seats ny and accessing these inputs when the cylindrical spring is unclenched to the back of the driver's seat, while fixing the cylindrical spring in the initial compressed state is carried out using a spring-loaded core installed here under the rear seat of an electromagnet, the field coil of which, like the shaped spring, are connected to the power supply system through a special button mounted on the floor of the passenger compartment at the feet of the driver.

The invention is illustrated by drawings, where Fig. 1 schematically shows a driver's seat and a rear seat behind a driver with the proposed protective equipment deployed beneath it in a disengaged state; figure 2 - the proposed tool in its original state before operation; figure 3 is a view A in figure 1 on an enlarged scale / the rear seat is shown by a dotted line /.

Means for protecting the driver 1 in the front seat 2 from attack / mainly from the side of the passengers 3 in the rear seats 4, which are outside the field of view of the driver 1 / is made in the form of a mechanism for restricting the movements of the passengers sitting behind the driver 1 by the rear seat area 4, which is an electromechanical device with simultaneous shock, fixing and current-damaging effects, placed under the seat 4 behind the driver 1 and made in the form of a twisted cylindrical spring 5 tension-compression, fully compressed using one state / cm. figure 2 /, placed along the longitudinal axis of the car in a plane parallel to its floor 6, approximately at the height of the legs of a person 3, attached to the floor 6 at the rear end using a special bracket 7 and provided with a rigidly fixed / welded / on the front end of the spring 5 orthogonal to it in on the same plane, by a passenger trap for passengers 3 in the form of a shaped flat spring 8 made of steel wire with turns 9 in the form of ring hinges-grips, overlapping along its length the entire width of the rear seat 4, facing the entrances 10 into the turns 9 towards the passage 11 ezhdu front 2 and rear 4 seats, and control the data inputs 10 windings 9 when decompressed the coil spring 5 to the seat back 2 of the driver 1, the fixation of the coil spring 5 in the initial, fully compressed state before activation, effected by means of a spring-loaded core 12 set here but under the rear seat 4 on the floor 6 of the electromagnet 13, the field winding of which, like the shaped spring 8, are connected to the power supply system through a special spring-loaded button mounted on the floor 6 of the passenger compartment the feet of the driver 1. The above connection diagram of windings spring-button actuators actuator / and simultaneously with the fitting of a spring steel wire 8 / sufficiently well known and developed, so the applicant on the electrical connection diagram does not dwell. The magnitude of the electrical signal in the circuit of the spring 8, which is the trap for the legs of the alleged attacker, is selected from the safety condition for the life of the passenger 3, but sufficient for an electric shocking effect on the body, forcing to immediately stop the aggressive actions. The norms and level of such electrical signals, combining life-safe and effective shock effects on humans, have been worked out in sufficient detail in the design of protective, enclosing, security, etc. devices in relevant fields of technology. The stiffness of the coils 9 of the steel spring 8 in the transverse directions, perpendicular to the longitudinal axis of the car in horizontal and vertical planes, on the one hand, should allow a tense passage during a foot strike of 14 / cm. figure 3 / passenger 3 through the inputs 10 into the turns 9 inward of these turns when the spring 8 hits the legs of the attacker 14 when triggered / straightened / spring 5 / rounded outer, facing the passage 11, the shape of the turns is 9 / cm. figure 3 / allows the attacker's leg 14 to go around this turn 9 and enter one of the inputs 10 /, but, on the other hand, should prevent attempts to release the captured leg either by pulling it back through the inputs 10 into the turns 9, or by pulling legs 14 up from the corresponding turn 9.

The work of the proposed means to protect the driver from attack is as follows.

In the initial state / cm. figure 2 / when ready for use, the coil spring 5 is fully compressed and fixed in this state by the spring-loaded core 12 of the electromagnet 13, which is included in the gap between the coils of the spring 5 near its working end facing the passage 11 between the seats 2, 4. In this case, the spring 5 together with the shaped spring-trap 8 are located under the rear seat 4 and remain invisible to passengers 3, the field windings of the electromagnet 13 and the closed steel wire circuit of the shaped spring 8 are de-energized. At the time of the attack of passenger 3 on the driver 1 / cm. figure 1 / passenger 3 is standing 14 feet on the floor 6 of the cabin and produces either the capture of the head of the driver 1, or an attempt to strangle, etc .; all this is either standing or sitting on the seat 4, leaning over the back of the seat 2 to the driver 1, however, the legs 14 of the passenger 3 in any case rest on the floor 6 of the cabin. It is also possible that these actions are preceded by threats, demands, etc. In this case, the driver 1 presses with his foot the spring-loaded button known to him on the floor in the area of his legs, in this case / cm. above / the power circuit is closed, the electric signal enters the excitation winding of the electromagnet 13 at the same time and feeds the shaped spring 8, the spring-loaded core 12 abruptly retracts into the coil of the electromagnet 13 and releases the coil spring 5, the last one “shoots”, completely unclenching along with the fixed / welded / to its free end with a shaped spring-trap 8, the latter pulling the edges of its annular turns 9 to the back of the seat 2 of the driver 1 at the rear, that is, it practically blocks the passage 1 1 between the seats 2, 4 both in width and in length / in the area of the width of the seat 4 /. With such a stroke of the shaped spring 8, the leg 14 of the passenger 3 at the level of his lower leg either immediately enters any input 10 between the turns 9 of the shaped spring 8 and slides into the coil 9 - traps, or, getting hit by the end face of the coil 9, due to rounding of the latter it jumps into a nearby entrance 10 into the turn 9. As a result, the foot 14 is pinched inside the turn 9 in all directions, and due to the passage of current through the spring 8, the attacker is simultaneously shocked by electric shock. Note that when the driver presses the button 1, the spring 5 “shoots” completely, that is, it does not return to its original compressed state, and the trap 8 must be removed from the attacker's leg 14, and the spring 5 must be recharged until it is ready to work, however, the electric pulse to the winding excitation of the electromagnet 13, and most importantly, the spring 8 is supplied only when the driver presses the spring-loaded button 1, after removing his foot from the button, the electrical signal is automatically removed. Therefore, a short-term pulse current should shock attacker, allowing driver 1 to free himself from the hold, etc .; naturally, if the attack continues, the driver repeats pressing the button, repeating the electric pulse, while the capture of leg 14 by the trap spring 8 naturally continues. or call the appropriate services by phone Naturally, when an attacker tries to free himself from being trapped by a spring trap 8 with the help of his hands, the attacker will get an electric shock on his hands. We specifically note that there are no fundamental difficulties in supplying with such protective equipment both the second rear seat and the seat next to the driver, while the inclusion of protective equipment can occur both simultaneously from one common button, and from different buttons / in the latter case, the process such inclusion by the driver must be worked out. The bottom bracket 7 using a special gasket / not shown / is not electrically isolated from the floor 6, which allows you to not electrically isolate the springs 5 and 8 from each other and connect them along the end of the spring 5 by welding / in this connection due to the cantilever of the spring 8 and the performance of its power function to capture and hold requires significant strength and rigidity of the connection /.

The proposed means of defense is characterized, according to the applicant, by the extreme simplicity of the structure, the effectiveness of the protection, versatility, high reliability of the structure and fixation of the attacker. It absolutely does not worsen the aesthetics of the cabin, is completely disguised from passengers, can be made even in artisanal conditions, does not cause passengers any discomfort, isolation, etc., allows you to use the effect of absolute surprise when acting on the attacker. In this case, this tool can perform various functions: short-term shock exposure to the attacker, enabling the driver to leave the car; rigid fixation of the attacker in order to capture him; strong traumatic effect on the attacker during a hard capture / armed attack, hostages, etc. /. Depending on the above functions, the amplitude of the electrical signal, the stiffness of the trapping elements, the magnitude of the impact of the coil spring when it is triggered, etc. must be changed.
