In the small passenger car side collision, driver and crew are very near apart from the hazardous location, cause Injury and death rate of accident very high.At present; current protection driver and crew's constrained system has side impact air bag and curtain air bag; can play buffer action in the collision between driver and crew and car body; to slow down driver and crew's head; chest; the impact that belly or hip are subject to; but this type of safety method has its limitation; only can reduce the extent of injury that driver and crew are subject to; can not fundamentally eliminate the threat that driver and crew are subject to; and the spread that is difficult to the control air bag just in time covers driver and crew's vital parts; and air bag can not play protection driver and crew's effect without expansive space when the car body deformation comparison is large.
Draw after deliberation 2 conclusions: the one, although the small passenger car safety system is more at present, death rate of accident is still higher.U.S.'s small passenger car chaufeur collision mortality is 56 (numbers/per 1,000,000 registered vehicle/years).If add on the same car probability that other occupants are dead, chaufeur is dead, and other accidents beyond colliding cause the probability of driver and crew's death, and data are about 100 (numbers/per 1,000,000 registered vehicle/years).The average useful life of small passenger car is 12 years, calculate with this, in the whole tenure of use of small passenger car, cause the probability of the extreme accident of driver and crew's death to be about 1200 (numbers/per 1,000,000 registered vehicle), i.e. 1.2 (number/per thousand registered vehicle), and cause the major accident probability of driver and crew's severe permanent disability will be higher.(the above data of China are higher than the U.S..) the 2nd, most driver and crew injured and dead all be confined to suffer in the car strongly or repeatedly bump also can't be escaped relevantly, simultaneously, the car space is less, mortality is higher.The data of U.S. express highway insurance association (IIHS) in June, 2011 issue show: in the four-door sedan, the chaufeur mortality of the car of build maximum when colliding is 46 (numbers/per 1,000,000 registered vehicle/years), and minimum car is then up to 82 (numbers/per 1,000,000 registered vehicle/years).Therefore, be badly in need of a kind of small passenger car lifesaving escaping of research and development system and allow driver and crew in case of emergency be launched car relatively narrow between clearancen, make driver and crew that a kind of method of carrying of the best be arranged in the most dangerous.
When not yet appearing at present small passenger car extreme major accident occuring, help driver and crew safely to break away from correlation technique and the device that the small passenger car car is escaped.
