HANS
HANS(It is the ず) with, "HEad AND NEck SWith the abbreviation of upport ", four wheels motor sport.
As a structure, helmet and the neck is connected with those of string condition, as for the part of the supporter of the neck having extended from the shoulder to the chest seat belt you hold down from above.
History
In the world of motor sport from former times, with the impact when crashing the head andCervical vertebraIt damaged the section and obstacle of the death or saving one life, it could see the case where the paralysis of one half of the body etc. remains mainly. Vis-a-vis being locked to the machine the result and the body where recently research advances concerning the reason by the seat belt, as for the head because it is not fixed, when it crashes at super high speed, just the head extremely the neck extends extremely by the fact that it becomes the front falling flat forward with the law of inertia, the steering wheel and the like the brain is damaged the head by the fact that you attach sluggishly, it became clear for the cervical vertebra to be damaged by the fact that the neck is pulled.
By the fact that is tied with the helmet and the supporter section of the neck the string etc. whose elasticity is low, when crashing the head becoming in the front falling flat forward, the fact that it was developed with whether it is not the neck extending extremely with the restriction of the string to be restricted, to be able to prevent the damage of the head and the cervical vertebra is HANS then. As the device of the kind of aim of being similar air bag is famous, but the air bag mechanism is complicated and HANS in addition to the fact that structure is simple, is assumed vis-a-vis the effect being thin in prevention of the damage of the cervical vertebra of those where the effect is high to installing in the racing car in addition to not facing, in the air bag in prevention of the damage of the head, that from the fact that among other things the effect is high, in the world of motor sport HANS lifesaving effect is higher even in prevention of the damage of the cervical vertebra.
HANS itself around 1980, at that timeThe Michigan state universityIt assumes that it was invented by Robert Hubbard which is the professor. At that time from around 1996 international automobile union (FIA) it was the top of the medical teamシド WadkinsBeing center, be able to advance improvement, at the beginning the United StatesIRL andCARTAnd so on spread advanced to the center. (With CART2001 year race/lace the installing HANS with oval course in obligation)
F12003 year besides the fact that, formula Japan road calls, formula car. In addition worldwide rally championship (WRC) with2005From HANS installing is obliged.NASCAR with デイトナ 500 2001デイル アーンハートThe accident which dies the spread of HANS advanced to opportunity.
Problematical point
HANS tying the helmet and the supporter with the string, has guaranteed safety by the fact that it restricts the movement of the neck inside the fixed range, but furthermore looking back at left and right as the side effect, there is a problem that "sight becomes narrow and rather it is dangerous", that it does to in the driver it becomes difficult, to verify the rear, even now, either the people who dislike the installing HANS are not few. Furthermore in the form which corresponds to that kind of claim, recently being thing to shake the neck on left and right, also HANS for the touring car race/lace which expands the angle which finishes exists.
In addition from cause such that form of the part of the shoulder where as for the appearance early time of HANS angle of the supporter is not agreeable, holds down with the seat belt is not agreeable, HANS slipping with the side G which is in the midst of travelling, also the problem that e.g., it could hurt, had been reported mainly the shoulder and the neck, but recently besides the fact that those where from first the pad is attached to the part where it hits against the shoulder of HANS have appeared, also angle of the supporter being custom-made, it reached the point where it can modify, conversely the body it decreased the example that largely with HANS it can hurt.
There is a price after as the big problem which remains. As for HANS being custom-made basically, it is necessary to be produced, but unless (so it does, the aforementioned way there is a possibility where the body it can hurt rather), because of that, at as of 2005 price 1000 dollars it does concerning 1 set being cheap. Furthermore really HANS plural you do not set do not prepare making provision for when attitude when driving differs, and the て does not become. But in the driver of subordinate category the fact that this expense does not become foolish, for HANS spread with subordinate category the voice which it points out that further cost reduction is necessary, is many.
