The text of the original in Russian Automatic head must still perform and their 'active' role, ie pleteobraznoe prevent the movement of the head upon impact in a car behind. According to British researchers, it is only in England, the total amount of insurance, payable annually in compensation to victims reaches 1.6 million pounds sterling. Companies known for their achievements in the passive security, create an entire system for such protection. For example, 'active' head, the mechanical action, and offer SAAB NISSAN, advanced toward the head, a 'system of protection against pletevogo head impact' (WHIPS) Company VOLVO moves the entire back of the front seat back in such a way as to reduce the load on the entire spine. Much easier, and cheaper is the idea, the creation of 'active' air head with persistent tubular section, through which are connected by air pockets - one in the seat, the other in the head. In rack mounted direct valves and check valves in the smaller size. In addition, the head, as opposed to overseas, has self-Side 'petals', to keep the head. The work of the head as follows. When struck in the rear of the car, spin the occupant impact on the seat in which the air cavity, it dramatically increases the air pressure. Under the influence of such a jump in pressure, the valves are opened directly incorporated in the desk of the head. As a result, air is moved to the head, increasing its volume to meet the head, and open side 'petals'. Thus, preventing head pletevye fluctuations, and thus reducing the risk of damage to the thoracic and cervical spine. In addition, the side 'lobes' cover his head with two sides and not allow it, if removed or re-strike, to deviate from the design. (Dimensions' active 'head increases, depending on the gravity of the car behind). Side 'lobes' of the head may be an alternative to the side curtains security, if the lateral' petal ', located from the pillar, will be longer. To this end, the side support of the chair should be given more air cavity and connect it with the flexible tubing uprights. Upon completion of the head of its protective function, created in the high air pressure, opens the check valves. The air from the head of the slowing moving into the air cavity of the back seat. Leveling air pressure in both cavities of the head and restores its original shape. Another advantage of such a head may be that in the long journey, 'provoking' filling the air and dismissing the head seat back, the passenger can safely rest, because his head will be located in a stationary position. This design will allow to equip not only the front but the rear seats of automobiles' active 'air head, which will significantly improve passive safety. |
