Description

The utility model relates to the safety of a passenger car, namely, devices for protecting pedestrians and car drivers in a collision with a pedestrian or animal and preventing their death as a result of falling through the windshield into the passenger compartment.

A number of inventions are known that relate to this subject, for example, JP H07156749 A, 06/20/1995. RU 2261187 C2, 09/27/2005. DE 102005048627 A1, 05.16.2007. FR 2927034 A1, August 7, 2009. US 2010269730 A1, 10.28.2010. DE 10014832 A1, 10/04/2001.

The closest technical solution chosen by the applicant as a prototype is a pedestrian and car driver protection device having an external airbag in the vehicle structure, which has a bucket shape, can close the windshield and is folded in the body compartment immediately in front of the windshield. With the concave side of the bucket, the airbag is facing pedestrians, and the airbag can consist of one continuous section or of several sections, inflated alternately as a result of partitions being installed inside its partitions with openings between the sections and ensuring the adoption of a bucket-shaped airbag (patent for invention of the Russian Federation No. 2547120 publ 10.04.2010).

The disadvantage of this design is that this design does not provide sufficient security, for example, if a person gets his head into the bucket, then fractures of the cervical spine are possible.

The technical task of the claimed utility model is to increase pedestrian safety in a collision with a car. And the protection of the driver and passenger from falling hit pedestrian in the car.

The technical result - the movement of a pedestrian after a collision with a car in a safe area for life.

The technical problem is achieved in that the pedestrian protection device in a collision with a car contains an external airbag in the vehicle structure, which has the ability to close the windshield, and in the initial position, the external airbag is folded in the body compartment, characterized in that the external airbag is when folded, it is located in the front bumper, and in the open position it is located downhill and has the ability to interact with the legs of a person, and on the outside the rone has vertical inflatable elements arranged in several rows, the device is additionally equipped with a trap airbag, which when folded is located on the roof of the car near the windshield, while the trap airbag in the open position forms a container with internal partitions and a back support and has the ability to move relative to the car body.

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

- the external airbag in the folded state is located in the front bumper, and in the open position it is located downhill and has the ability to interact with the legs of a person

- the external airbag on the outside has vertical inflatable elements arranged in several rows;

- the device is additionally equipped with a trapping airbag, which when folded is located in the engine compartment of the car near the windshield;

- a trapping airbag in the open position forms a container with internal partitions and a rear support and has the ability to move relative to the car body;

Therefore, we can assume that the claimed utility model meets the criterion of "novelty."

A utility model can be manufactured using well-known equipment and processes, therefore, it meets the criterion of "industrial applicability".

The figure 1 shows the inventive device in its original position, figure 2 shows the inventive device with open pillows. The figures show the following items.

1. A computer control unit that analyzes information from the pedestrian detection unit and sends out a signal for the deployment of airbags.

2. Pedestrian detection unit.

3. Two coils with spring-loaded cables installed in the engine compartment under the hood, fixed at one end to the bottom of the trap airbag, so that when a pedestrian enters the trap airbag, its weight will facilitate the free movement of the trap airbag relative to the car body, against the direction of movement of the car , and did not receive a dynamic shock when passing through the partitions and the rear wall of the trapping airbag.

4. An external airbag, when deployed, forming a flat inclined surface, containing vertical inflatable elements 7 located in several rows on the outside, interacting with the pedestrian's legs and his body and promoting his safe movement through vertical inflatable elements that protect a person from unwinding in flight and body blows on car parts. When folded, the pillow is in the front bumper of the car.

5. The trapping airbag, which is in the folded state in front of the windshield of the car. In the disclosed provisions, this airbag is a container with partitions 8, which can be made in the form of a mesh or the like, and are made of easily destroyed material upon impact, for example: nylon, geotextiles, polyethylene and other materials. The thickness of the partitions is selected so that the pedestrian, due to inertia, with his body can freely break the partitions without harming himself. The fabric of which the airbag is made can be reflective to provide visibility in the dark. The deployed airbag has a rear support 9 in order to protect the pedestrian from a possible impact on the road surface.

6. The body of the car.

The device operates as follows:

When a pedestrian is detected, the pedestrian detection unit 2 transmits a signal to the computer control unit 1. The computer control unit 1 sends a control signal to the airbags 4, 5. Then they are activated. An external airbag 4 interacting with the legs and body of the pedestrian prevents it from falling under the wheels a moving car, and the vertical inflatable elements 7 exerting resistance, quench speed and reduce the possibility of multiple turning over of a pedestrian, i.e., stabilize its movement. A downed pedestrian by inertia moves along the outer surface of the airbag through vertical inflatable elements 7 and enters the trapping airbag 5, which when opened is a container with partitions inside. A downed pedestrian, falling into the capacity of the airbag 5, breaks partitions 8 with its body and gradually loses speed. At the same time, due to its pressure on the trapping airbag 5, it moves relative to the car body, opposite to the car movement, while the spring-loaded cables of the coils 3 are stretched. The rear support 9 prevents the pedestrian in the tank 5 from impacting the road surface behind the car.

Thus, the claimed utility model can improve pedestrian safety in a collision with a car and significantly reduce the possibility of death.
