Novel expansion type safety air bag assembly

Abstract

The invention discloses a novel expansion type safety airbag assembly, which belongs to the technical field of automobiles, and comprises a seat backrest and a safety airbag assembly, the safety airbag assembly comprises a wiring harness assembly, a first airbag and a second airbag, wherein the first airbag and the second airbag are connected through the wiring harness assembly. The first air bagand the second air bag are installed on a side face metal plate framework of the seat backrest, the wiring harness assembly is clamped into a rear foam groove of the seat backrest, and the upper faceof the wiring harness assembly is covered with the seat skin. An air bag connector of the wire harness assembly is connected with a vehicle body wire harness. The safety air bag assembly is used in cooperation with the electric pre-tightening safety belt; the air bag assemblies are arranged on the two sides of the seat backrest. No matter how each seat in the vehicle faces; when the vehicle control system detects that collision is inevitable, the electric pre-tightening safety belt tightly binds a passenger on the seat, the air bags are popped out from the two sides of the backrest of the seatto annularly surround the passenger, secondary collision between the passenger and vehicle interior trim is avoided, and the safety of a driver and passengers can be protected under the L4-level andL5-level automatic driving situation in the future.

Description

technical field [0001] The invention belongs to the technical field of automobiles, and in particular relates to a novel deployable safety air bag assembly. Background technique [0002] While automobiles provide comfort and convenience to people's lives, road traffic accidents that occur during automobile driving also pose a huge threat to people's lives. As a result, the industry is also continuously investing in research on automobile safety systems to improve automobile safety. safety performance. [0003] With the development of the four modernizations of automobiles, especially the advancement of "intelligence", smart cars with L4 and L5 autonomous driving will not need the driver to operate in the future. In this case, the driver will not need to hold the steering wheel , step on the clutch pedal, brake pedal and accelerator pedal, the car is full of occupants, and the occupant's seat does not need to be fixed forward, but can rotate freely, and the corresponding occ...

Problems solved by technology

[0004] In order to overcome the problems in the prior art that the conventionally arranged steering wheel airbags, instrument panel airbags, seat side airbags, side curtain airbags, and knee airbags lose their protective effects in the event of a collision accident, the present invention provides A new type of deployable airbag assembly is developed. The airbag assembly of the present invention is used in conjunction with electric pre-tensioning seat belts. The airbag assembly is arranged on both sides of the seat back. When the system detects that a collision is unavoidable, the electric pre-tightened seat belt will bind the occupant tightly on the seat, and the airbags will pop up from both sides of the seat back to surround the occupant in a circle to avoid secondary collision between the occupant and the vehicle interior. Protect the safety of drivers and passengers under L4 and L5 automatic driving scenarios in the future
