Description

The invention relates to vehicle safety, and in particular to devices forcing a vehicle to stop in a collision with an obstacle and preventing the death of a driver and passengers.

A number of inventions are known that relate to this topic, for example, patents of the Russian Federation 52870, 87007, 100091, 153738.

One of the closest technical solutions is the device for protecting pedestrians and car drivers, which has an external airbag in the vehicle structure, which is located in the front bumper zone (patent for utility model of the Russian Federation 166337, publ. 20.11.2106).

The technical problem is to save the life of the driver and passengers of the car in a collision with an obstacle.

The technical result is the provision of an emergency stop of the car in front of an obstacle.

The technical result is achieved by the fact that the device for forcing the car to stop contains an external pillow in the vehicle structure, which when folded is located in the front bumper zone, characterized in that the device contains an additional airbag, which when folded is also located in the front bumper zone, and in the open position, the pillow is located in front of the car, made in the form of a dome and has a tongue facing the front of the car, with an additional pillow armar Wang grid and has its own grid station equipped with needle-like elements, the outer pad in the open position is located between the bumper and an additional airbag.

Comparison of the claimed technical solution with the prototype shows that it differs in the following features:

- the device contains an additional airbag, which when folded is also located in the area of the front bumper;

- an additional airbag in the open position is located in front of the car;

- an additional airbag in the open position is made in the form of a dome;

- An additional airbag has a tongue facing the front of the car;

- An additional airbag reinforced with mesh;

- an additional airbag has an independent section of the grid, equipped with needle elements;

- an external airbag in the open position is between the bumper and the additional airbag.

Therefore, we can assume that the claimed technical solution meets the criterion of "novelty."

The invention can be manufactured using well-known technical means, therefore it meets the criterion of "industrial applicability".

A feature of this design is that an additional airbag due to an independent section of the mesh with needle elements and tongue is pulled under the front of the car, lifting it, while a deformation wave arises in the pillow, formed by the bumper of the car, which damps the remaining speed.

The applicant as a result of patent information research, the claimed combination of features was not identified, therefore, we can conclude that the invention meets the criterion of "inventive step".

In FIG. 1 shows the inventive device in its original position, side view; in FIG. 2 - the claimed device in an open form, side view; in FIG. 3 - additional airbag.

In FIG. 1-3 show the following items:

1. The body of the car.

2. The control unit.

3. A detection sensor unit located on top of the vehicle.

4. An additional airbag reinforced with mesh, located in the area of the front bumper. In the open position is dome-shaped.

5. External airbag. When folded, also located in the front bumper area. In the open position, the airbag is between the bumper and the additional airbag 4.

6. Independent section of the grid for winding on the wheels of the car. Structurally attached to an additional airbag 4 and is equipped with needle elements 8. In the unopened position, it is located in front of the front wheels.

7. Pressure relief valve after the vehicle is completely stopped.

8. Needle elements installed on an independent section of the net, which helps to ensure that the net is wound on the wheels of the car.

9. The tongue facing the front of the car, which is a structural element of an additional airbag 4.

The device operates as follows.

If a collision hazard is detected, the driver brakes sharply and extinguishes part of the vehicle’s speed. The detection sensor unit 3 transmits a signal to the control unit 2. The control unit 2. sends a control signal to an additional airbag 4. and an external airbag 5.

Then they are triggered. For example, when the collision of a given car with an obstacle is inevitable, an additional airbag 4 opens, forming an inclined dome surface with a tongue 9. At the same time, an additional airbag 5 is deployed simultaneously with the deployment of an additional airbag 4, preventing the fabric of the additional airbag 4 from breaking in the front of the vehicle 1. During the deployment of airbags 4 and 5, a separate portion of the net 6, equipped with and with hollow elements 8. In this case, an independent section of the net 6 is attached on one side to the additional airbag 4, and with the other side, with the help of needle elements 8, it is wound on the front wheels of the car 1, first pulling the tongue 9, and then the additional airbag 4 under the lower part of the car 1 The front of the car rises, and a deformation wave occurs in the additional airbag, which dampens the remaining speed of the car. After stopping the car through valve 7, pressure relief and folding of the additional pillow 4 are carried out.

Thus, the claimed invention reduces the likelihood of death of the driver and passengers in the car.
