Passenger side air bag restraint system reinforcing frame

Abstract

The invention provides a passenger side air bag restraint system reinforcing frame which comprises an air bag reinforcing frame body. The air bag reinforcing frame body comprises a base plate and a side frame body. An air bag door is formed on the base plate. The bottom face of the side frame body is fixed to the periphery of the air bag door. The area of the base plate is larger than the area formed by surrounding the bottom face of the side frame body. At least one strength weakening structure is formed on the side frame body or the side frame body and the base plate form at least one strength weakening structure. The strength weakening structure comprises an open slot. The passenger side air bag restraint system reinforcing frame is provided with the strength weakening structure, on the basis of ensuring the safety and stability of the air bag explosion process, the requirement for energy absorption of collision collapse in the national standard GB11552 is met, and the passenger side air bag restraint system reinforcing frame has the advantages of being simple in structure, low in cost and high in safety.

Description

technical field [0001] The invention relates to the field of automobile safety airbags, in particular to a passenger side safety airbag reinforcement frame. Background technique [0002] At present, in order to reduce the injuries caused by collision accidents during driving, most vehicles will be equipped with airbags. The airbag on the passenger's side is arranged inside the instrument panel, and is connected to the instrument panel through the airbag reinforcement frame, which is used to fix the airbag and guide the expansion direction of the airbag after it explodes. see figure 1 The passenger side airbag structure of the existing automobile generally includes: an airbag reinforcement frame 1', an instrument panel body 4', an airbag module 5', two airbag brackets 6' and a metal beam 7', and the airbag reinforcement frame 1' uses vibration friction It is connected to the instrument panel body 4' by welding, and the airbag module 5' is fixedly installed in the side frame...

AI Technical Summary

Problems solved by technology

[0003] In order to ensure the stability of the airbag blasting process, the existing airbag reinforcement frame usually has relatively high strength, so that the instrument panel area where the airbag reinforcement frame is installed is also strong, which cannot meet the energy absorption requirements for collision collapse in the national standard GB11552

When a passenger hits the instrument panel assembly 4' accidentally or due to external factors, the collapse amount of the surface of the instrument panel assembly 4' will be small, and the surface of the instrument panel assembly 4' will resist and absorb most of the collision energy. The energy is not effectively transmitted to the airbag bracket 6' and the metal beam 7', and the impact energy cannot be effectively absorbed. The instrument panel cannot relieve the impact energy of the passengers on the instrument panel, and when the impact speed is high, it will cause greater damage to the passengers. harm

[0004] At present, in order to solve the above problems, the structural design of the instrument panel is usually changed, but these changes often bring about the problems of large amount of mold modification, high cost, and long cycle time, and every time the structure is changed, airbag blasting and collision tests are required. Verification, which greatly increases the development cost
