Problems solved by technology

It is worth noting that the designed airbag cannot effectively cover the rear end of the fender, and for passenger cars with obvious fenders, the rear end of the fender is also a dangerous area that can cause serious head injuries to pedestrians
Invention 200780003217.6 designed a similar airbag shape (U-shaped), and mentioned the possibility of the airbag extending to cover the fender, but did not give a specific plan

Embodiment Construction

[0022] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific illustrations.

[0023] see figure 1 , figure 2 The relevant schematic diagram of the preferred embodiment of the pedestrian head injury protection system based on the H-type airbag, in this embodiment, includes the airbag 11 and the installation box, and the airbag 11 is foldable and placed in the strip-shaped installation box 17, Then the installation box 17 is placed in the water tank at the rear end of the engine cover 15 and fixed, as figure 2 shown. The installation box 17 can be divided into a middle section and two side sections, such as image 3 The two sides of the shown mounting box 17 are bent back. Such as figure 1 As shown, the airbag 11 can cover the front windshield 12 , A-pillar 13 and part of the fender 14 after deployment.

Abstract

The invention provides a pedestrian head injury protection system based on an H-shaped safety air bag, and discloses a pedestrian head injury protection system mounted on the rear end of an engine hood of a passenger car. The system consists of a mounting case, a gas generator, a gas pipe, a pull rope and an air cell. When a pedestrian is hit by a vehicle and the air bag trigging conditions are met, the air bag, under the action of an inflation device, expands and unfolds while the gas enters the H-shaped air bag, and covers a windscreen, an A post and a wing sub-wing area, and thus, the head injury risk of the pedestrian in a pedestrian-vehicle collision accident.

Description

technical field [0001] The invention relates to a safety airbag device for pedestrians, specifically a H-based airbag device installed on a passenger car that can be used to protect the head of a pedestrian in an accident where the passenger car collides with a pedestrian (or a two-wheeler) Pedestrian head injury protection system with type airbag. Background technique [0002] In the known pedestrian protection airbag device, the airbag is folded and installed at the rear end of the hood. When a collision accident occurs between a passenger car and a pedestrian, the airbag is inflated and deployed along the outer surface of the car. The airbag after deployment covers the lower end of the entire front windshield, and Extends to cover the lower end of the A-pillar. Pedestrian airbags can cushion and absorb energy during a collision, reducing windshield and A-pillar damage to pedestrians' heads. [0003] The similar pedestrian protection airbag device shall be able to cover ...
