Purpose of the present invention: purpose of the present invention exempts from the huge injury that is brought behind the auto against for the thigh of better protection occupant in the process that bumps at automobile.
Along with the increase of automobile pollution, the trap for automobile traffic accident is risen year by year, has become the big public hazards in the global range.According to incompletely statistics, about more than 3,600 ten thousand people of number that road traffic accident is died from the whole world since the own automobile, more than the number of World War II death, the financial losses that cause are also very huge.With the U.S. is example, and the number because of motor traffic accidents death reached 43536 people in 1994, accounts for half of death toll sum that various accidents cause.The traffic accident of China increases year by year with automobile and is concussion rising situation substantially, in recent years along with personal car purchase enthusiastically, road accident increases year by year, sees Fig. 4.
According to statistics, 2000, national public safety traffic management department accepted 61.7 ten thousand of road traffic accident cases altogether, because of road traffic accident causes 9.4 ten thousand people's death, 41.9 ten thousand people injured, 26.7 hundred million yuan of direct economic losses increase by 49.4%, 12.4%, 46.4% and 25.7% respectively than the last year; Ten thousand car mortality are by rising to 15.6 15.5 of last year.Annual 58 of the above especially big traffic accidents of once dead 10 people taking place altogether, cause 910 people's death, 960 people injured, increase by 3.6%, 2.0% and 12.4% respectively than the last year, but the passenger vehicle serious accident that takes place reduces 7.6% than the last year.Compared in first 1978 with reform and opening-up, the accident number of times was 3.85 times in 1999, and death toll is 4.37 times, and number of injured people is 3.70 times, and direct economic loss is 37.93 times.
Because road environment of living in and self-technique condition is different, traffic accident shows different accident form characteristics.Enter the eighties, the vehicle safety problem of China begins to become very severe.Compare with western developed country, relative datas such as the traffic accident incidence of China, unit kilometer death toll have all exceeded an order of magnitude, automotive safety level even lag behind many developing countries.Automotive safety has become one of the factor that China Transportation Industry and auto-industry further develop that hinders.Governability and user's request are progress of propelling vehicle industrial technology and the two big power that improve constantly vehicle safety.In the face of serious traffic accident problem, many countries as the U.S., Japan and european community country, have all formulated strict legislative control on safety and standard.Meanwhile, abroad about the research of automotive crash safety aspect also as far back as the sixties with regard to carrying out of system, and obtained development at full speed.Along with implementing of legislative control on safety and carrying out of automotive safety Journal of Sex Research, the traffic mortality of many countries reduces greatly.In the U.S., 15.6 people of per hundred million kilometers death tolls during by the summit reduce to 3.5 people in 1980, reduce to 1.8 people again, and effect is very remarkable.
In today that world's auto-industry constantly develop and grow in strength, especially along with the continuous popularization of express highway, it has been recognized that because the effect of unexpected factors such as chaufeur itself, road environment, weather, technology state of vehicle, traffic accident can not be avoided fully, occupant's safety when how to guarantee collision to greatest extent, the injury that the minimizing accident causes, the safety that improves automobile has important practical significance.Safety has become one of three great development directions of modern automobile technology, and it will substitute the priority factors that quality and price become the automotive market competition gradually.
