RU166333U1 - 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, having the ability to interact with the legs of a person and catching guide airbag is folded is located on the car roof at the windscreen, thus catching the airbag in an expanded position forms a capacitance, and an outer airbag located in the open position under bias.

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 to protect 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.

In FIG. 1 shows the inventive device in its initial position, FIG. 2 shows the inventive device with the pillows open, FIG. 3 is a front view of an open trap airbag.

The figures show the following items:

1 - car body;

2 - control unit;

3 - a block of two infrared cameras and radars 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;

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).

The device operates as follows.

When a pedestrian is detected, a unit of two infrared cameras and radars 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 a pedestrian 3 does not allow him to fall under the wheels of a moving car and direct impact 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.

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

Claims (1)

A pedestrian protection device in a collision with a vehicle, comprising an external airbag in the vehicle structure, which can cover 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, having the ability to interact with the legs of a person and catching guide airbag is folded is located on the car roof at the windscreen, thus catching the airbag in an expanded position forms a capacitance, and an outer airbag located in the open position under bias.
