RU166330U1 - PEDESTRIAN PROTECTION DEVICE WHEN COLLISING WITH A CAR - Google Patents

Abstract

A pedestrian protection device in a collision with a vehicle, comprising an external airbag in the vehicle structure, which is able to close the windshield, and in the initial position, the external airbag is folded in the body compartment, in front of the car windshield, characterized in that the device contains an additional pillow when folded, located in the front bumper, and in the open position, able to interact with the legs of a person, and catching the airbag, which when folded, is located on the car roof near the windshield, while the trap airbag in the open position forms a container with internal partitions and a rear support, and the external airbag in the open position is inclined, while the airbag traps in open position has the ability to move relative to the car body.

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, JPH 07156749 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 by the fact that the pedestrian protection device in a collision with a car contains an external airbag in the vehicle structure, which is able to close the windshield, and in the initial position, the external airbag is folded in the body compartment, in front of the windshield of the car, while the device contains an additional airbag, when folded, located in the front bumper, and in the open position has the ability to interact with gamma man and a trapping airbag, which when folded is located on the roof of the car near the windshield, while the trapping airbag in the open position forms a container with internal partitions and a rear support, and the outer airbag in the open position is located at a slope, while the airbag in the open position has the ability to move relative to the car body.

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

- the device contains an additional airbag, when folded, located in the front bumper, and in the open position having the ability to interact with the legs of a person;

- the device contains a trapping airbag, which when folded is located on the roof of the car near the windshield;

- a trapping airbag in the open position forms a container with internal partitions and a rear support;

- an external airbag in the open position is located at a slope;

- trapping airbag in the open position 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 processes, therefore, it meets the criterion of "industrial applicability".

In FIG. 1 shows the inventive device in its initial position, FIG. 2 shows the inventive device with the pillows open, FIG. 3 shows the position of a trap airbag when moving relative to a car body; FIG. 4 shows a front view of an open trap airbag using mesh screens, FIG. 5 is a front view of an open trap airbag using perforated baffles.

The figures show the following items:

1 - car body;

2 - control unit;

3 - a block of two infrared video cameras, radars and lidars located in the housing of the right and left headlights (viewing angle of the radar and camera 270 °);

4 - an additional airbag interacting with the legs of the pedestrian (the airbag is in the front bumper when folded, Fig. 1).

5 - an external airbag having the ability to close the windshield and facilitates the movement of the human body along an inclined plane (the airbag is folded in the body compartment, in front of the windshield).

6 - trapping airbag (the airbag is folded on the roof of the car in front of the windshield). In the open position, the airbag is a container with partitions 7 inside, which can be made, for example, of polyethylene, or geotextiles of such a thickness that a downed pedestrian, due to inertia, can make them burst with their body, thereby offsetting their speed. Partitions can be made in the form of a grid, or with holes, etc. (Fig. 4, 5). The disclosed pillow 6 has a rear support 8, for example, in the form of a ring, so that the pedestrian in the tank does not hit the pavement behind the car after speeding off. Another feature of the device is that the deployed trap airbag 6 has the ability to move relative to the car body. To do this, it is attached to the coil 9 with a stretched spring-loaded cable.

The device operates as follows.

When a pedestrian is detected, a block of two infrared cameras, radars and lidars 3 detects an obstacle and transmits an warning signal to control unit 2 in advance. Control unit 2 sends out a control signal to airbags 4, 5, 6, and then they are triggered, with an additional airbag 4 interacting with the feet of the pedestrian 3 does not allow him to fall under the wheels of a moving car and a direct hit with the front of the car. A downed pedestrian by inertia moves along an external airbag 5 located on a slope and then falls into a trapping airbag 6, which when opened is a container. A downed pedestrian, falling into the capacity of the airbag 6, breaks partitions 7 with its body and loses part of the speed. The rear support 8 prevents the impact of a pedestrian in the tank 6 on the road surface behind the car. At the same time, the open airbag 6 is moved relative to the car body on the spring-loaded cable of the coil 9. This leads to the damping of the remaining part of the pedestrian speed.

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