It should be borne in mind that in the description of the invention, the implementation of a particular case of the invention is considered on the example of a car, however, the claimed system can be applied to other land, air and water vehicles.

Means for ensuring the safety of the driver and passengers include a protective capsule 2 (Fig. 1) located inside the vehicle 1, consisting of durable inflatable shells 3 forming a closed frame. Inflatable shells include or are connected to a gas source and contain safety valves 4 that operate when the permissible pressure inside the shells is exceeded. Gas source - a hybrid gas generator that produces a mixture of gases from a pyrotechnic battery and a container with compressed gas in accordance with application No. 2004132520 “Combined gas source”.

Shock absorbing panels 5 are attached to the inflatable shells (FIGS. 2, 3), which can be made in the form of sealed volumes, under tension, including the shape of a parallelepiped, as well as in the form of leaky volumes (shell or bag) with a flap valve 6, providing suction of air into the shell when it is stretched. When the shells 3 of the frame are inflated, the shock-absorbing panels form an additional protective shock-absorbing pillow.

The protective capsule 2 can be divided into compartments by partitions 7 located between the rows of seats of the vehicle.

The closed capsule frame, consisting of durable inflatable shells 3, is attached to the supporting structure of a vehicle, such as a car. Inflatable shells 3, decoratively designed as part of the interior of the car, can be located on the surface of the skin of the passenger compartment and have an L-shaped, cylindrical or any other shape convenient for solving the task. The inflatable shell 3 of the protective capsule 2 can be placed in the opening cells of the skin. Inflatable shells 3 must be placed on the supporting structures of the ceiling, floor and walls of the cabin, as well as at their intersections.

The driver must be protected from the steering wheel by a separate inflatable shell 8 made of an elastic material with a heat-shielding coating or simply of an elastic non-heat-conducting material.

Shock absorbing panels 5 may contain shock absorbing materials or autonomous gas sources inside. In the idle position, compactly packed (assembled) shock-absorbing panels are placed in places most convenient for vehicle users, including on the side surfaces of the passenger compartment in the form of curtains.

The shock-absorbing panels 5 are attached to the shell 3 of the frame or worn on them, i.e. cover the inflatable shell 3 of the frame, or secured with clamps made of material panels. The towels are interconnected by well-stretched rubber belts or screeds 9. When placed on a vehicle, the towels are spread as far as possible and secured to the pins 10. When the shells 3 of the carcass are inflated, the shock-absorbing cloths 5 jump off the pins 10 and stretch, forming shells with parallel side walls. In the working position, the carcass inflatable shells and shock-absorbing panels form a protective capsule 2 located inside the vehicle 1. At the same time, the shock-absorbing panels 5 along the perimeter limited by the carcass inflatable shells form additional airbags that cover all solid parts and objects in the vehicle compartment and protect users from damage during a sudden stop of the vehicle.

To give additional strength to the protective capsule 2, the frame can be equipped with structural elements, such as inflatable stiffeners, in places that do not interfere with the users of the vehicle.

Means for protecting the vehicle from the outside include a frame of durable inflatable shells 11 (Fig. 4), interconnected by elastic stretch belts, on the outside of the car. The inflatable shell 11 can be mounted on the outer surface (lining) of the vehicle and have any convenient shape, for example, L-shaped or cylindrical.

Along with fastening on the outside of the vehicle, it may be possible to arrange the shells 11 of the frame in the cells of the vehicle body (body) that open when inflated. Cells can be made with either one or two opening sashes.

In addition, means to ensure vehicle protection include multilayer shock-absorbing protective elements located on the vehicle body at the sites of the most frequent or probable collision, for example, for a car this is a bumper (Fig. 5). Multilayer shock absorbing elements provide soft and effective damping, which is important in collisions with living objects, such as a person. Multilayer shock-absorbing elements include: a layer of reinforcing and shock-absorbing structural elements 12; a layer comprising sequentially located external inflatable shells 13, shock absorbers 14, which can be made of corrugated spring tape; inner inflatable shells 15, shock absorbers 16, which can be made of corrugated metal spring tape. Moreover, the outer and inner shells are located in the hollows of the corrugated tape 14. Outside, the multilayer device is covered with a cover 17. The outer inflatable shells 13 should extend beyond the corrugated spring tape 14. When inflating, the outer inflatable shells are made of elastic rubber. They are equipped with collision blow-off relief valves that provide non-rigid cushioning.

Means for ensuring vehicle protection include a device for capturing and holding an object in front of a moving vehicle, located in front of the bumper (Fig.6, 7) and / or under the underbody in front of the front wheels (Fig.8). Such a device can be made in the form of lower 18 and upper 19 cylindrical rigid pipes or flexible shells, inflated to touch each other at the time of collision with an object. The upper shell 19 has a larger size than the lower 18, and is equipped with elastic hooks 20 to capture an object lying on the road. The lower shell 18 has a smooth surface. The device for capturing and holding an object in front of a moving vehicle may also be a cylindrical flexible shell 19, inflated at the moment of collision with an object or thin-walled plastic or metal pipe 18 (Fig. 8), lowered at the moment of collision with the road.

In addition, additional flexible inflatable shells 21 are placed on the roof and bottom of the vehicle to cushion when the vehicle falls from a height and ensure its unsinkability (buoyancy), and flexible shells 22 are placed around the perimeter of the vehicle to cushion during collisions and enhance buoyancy (Fig. 9).

Means for ensuring the protection of the vehicle also includes the "harpoon gun" 23 (figure 10, 11), mounted in the lower part of the vehicle. The gun at the signal of the control system shoots into the ground or pavement. "Harpoon" attached to the winch 24, mounted on a machine, shock-absorbing cable.

The vehicle security system control system may be taken from the prior art. For example, it is made on the basis of an aviation system for continuous monitoring of changes in the trajectory of the aircraft and the aviation system for preventing collisions.

In addition, the passive safety system of an automobile vehicle, including airbags, developed at a modern level, works:

- by the signal of the control subsystem, depending on the threshold value of deceleration recorded by acceleration sensors;

- when proximity sensors are triggered, taking into account the probability of a vehicle colliding with other objects;

- from sensors measuring the disturbance of an electromagnetic or magnetic field generated by sources located in front, behind and / or on the side walls of the vehicle.

The system may include a radar device located on the roof of the vehicle with the possibility of a full view. With the help of the radar, objects located in a dangerous proximity to the vehicle are detected. In the event of a collision hazard, an alarm is triggered, when a threatening approach and the intersection of the vehicle path and the detected object occurs, the security system automatically triggers.

The security system for vehicles used in extreme situations may include a parachute quick-acting system 25 located in the roof of the hull (Fig.9).
