Abstract

FIELD: mechanical engineering.

SUBSTANCE: device includes set of transducers for detection of car overloading and control module, which is electrically connected with actuating devices of gas generators, and outer safety airbag that is provided with aperture opposite to driver seat and inflated from under bonnet. This airbag envelopes car's windscreen, front pillars and front edge of roof. From the side of external damping surface the gas-filled outer safety airbag is surrounded with boards placed along left and right edge. Internal side surfaces of said boards are parallel to longitudinal axis of car and perpendicular to road plane. Along upper edge this airbag is placed opposite to board connected with mentioned boards. Front and rear surface of this board are perpendicular to symmetry axis of windscreen.

EFFECT: invention provides passive safety of pedestrians and traffic participants, who move on two-wheel vehicles, in the case of their collision with front of passenger cars.

Description

The invention relates to the automotive industry, in particular to devices that provide passive safety for pedestrians and road users traveling on two-wheeled vehicles when they collide with the front of cars.

A known car passive safety system comprising a set of overload sensors and a control unit electrically connected to actuators of gas generators, and an outer ring-shaped airbag inflated from under the hood and in the unfolded state covering the car windshield with front struts and front edge of the roof. The annular shape of the outdoor airbag in the deployed state is provided by a mesh stretched between the inflatable elastic components of the airbag and not interfering with the view, which allows the driver to control the traffic situation after the system has been deployed and the airbag inflated (DE patent 10102597, 2002).

The disadvantage of this system is the inability due to the grid in the central part of the airbag to protect pedestrians and road users traveling on two-wheeled vehicles, when they collide with the front of the car, from hitting their head on the windshield of the car.

The closest in technical essence to the proposed device is a passenger car passive safety system containing a set of car overload sensors and a control module connected electrically to the actuators of the gas generators, and an external airbag inflating from under the hood and covering the car windshield with front struts and front edge of the roof. To ensure that the driver can control the traffic situation after the system is activated and the airbag inflates, it has an opening opposite the driver’s seat (RF patent No. 123378, 12/27/2012. Bull. No. 36).

The disadvantage of this system is that as a result of a collision between a pedestrian or a road user traveling on a two-wheeled vehicle (hereinafter referred to as a participant), with a car and then an external airbag, a pedestrian (participant) may roll left or right from this airbag (when driving in second, third, etc. row) under a vehicle running in an adjacent lane or roll over the roof of this car and get under a vehicle running behind it.

The technical result of the proposed device for ensuring the safety of a vehicle is to increase the protection efficiency of pedestrians and road users traveling on two-wheeled vehicles when they collide with the front of the car and its external airbag due to the constructive counteraction of this external airbag to the movement of a pedestrian (participant) after his contact with her to the left and right of this car under the trance going along the adjacent lane sport and through the roof of this car back underneath a running vehicle.

The specified technical result is achieved by the fact that in the device for ensuring vehicle safety, comprising a set of vehicle overload sensors and a control module electrically connected to actuators of gas generators, and an external airbag with an opening opposite the driver’s seat, inflating from under the hood and covering the windshield vehicles with front pillars and front edge of the roof, gas-filled external airbag on the side of the external damping surface has on the left and right edges of the side, the inner side surfaces of which are parallel to the longitudinal axis of the car and perpendicular to the plane of the road, and on the upper edge there is a side connected to the indicated sides, the front and rear surfaces of which are perpendicular to the axis of symmetry of the windshield, counteracting the movement of the pedestrian (participant) after its collision with the airbag to the left and right of this car under the vehicle running in the adjacent lane and through the roof of this car back under the rear running conveyor .

The drawing shows a diagram of the proposed device to ensure the safety of a vehicle with a cross section of an outer deployed (gas-filled) airbag (the opening in the pillow opposite the driver’s seat is not shown).

The proposed device for ensuring the safety of a vehicle includes a set of overload sensors for a vehicle 1 and a control module 2, electrically connected with actuators of gas generators 3, an external airbag 4 (shown in the deployed state) with an opening opposite the driver’s seat, which is on the side of the external damping surface has: on the left and right edges of the side 5, 6, the inner side surfaces of which are parallel to the longitudinal axis of the car and perpendicular to the plane d horns (horizontal plane), and the upper edge - sides connected to said board 7, the front and rear surfaces of which are perpendicular to the axis of symmetry of the windshield. The front ends of the sides 5 and 6 are connected with the front end of the airbag 4 with scarves (pads) - not shown in the diagram.

The proposed device for ensuring the safety of a vehicle is as follows. When longitudinal overloads occur during a traffic accident on sensors 1, the control module 2, connected electrically to the actuators of the gas generators 3, is activated and the inflatable elastic component of the external airbag 4 with sides 5, 6 and 7 are filled with decomposition products (combustion) of the gas generating composition in the gas generator 3, reducing injuries in the collision with this pillow of pedestrians and road users traveling on two-wheeled vehicles, and counteracting these olnennymi gas sides pedestrian movement (party) after a collision with an airbag left and right of this vehicle under traveling on the adjacent lane transport and through the roof of the car back under the back of oncoming traffic.

Thus, the proposed device for ensuring the safety of a vehicle allows for the effective protection of pedestrians and road users traveling on two-wheeled vehicles when they collide with the front of the car due to damping by inflatable airbag elements and counteracting the sides of this airbag to move the pedestrian ( participant) after his collision with the airbag to the left and right of this vehicle under the next lane is transport and through the roof of this car back underneath a running vehicle.

Claims (1)
