Impact force.But in a very long time, when being threatened in face of land mine and improvised explosive devices (IED), the attention of people
Be concentrated mainly in the plate armour of vehicle itself, will prevent vehicle it is breakdown be considered as in explosive incident it is most important, be also most urgent
Demand, and the problem of seldom pay close attention to occupant.With the raising of Vehicle protector level and survival ability, though the Casualty Vulnerability Number of personnel
It has so declined to a great extent, but the injured situation of some types but increases instead, and the death rate caused by quadratic effect is still
It is so high, even those are mounted with that the vehicle of early stage Explosion protection seat is no exception.Among these situations, most enable
The number of people ache the problem of first is that be referred to as " knock-on effect " the case where, that is, the impact force to explode is even across car body and explosion-proof seat
Blocking, but excessive acceleration is still applied with to human body.
The explosion-proof seat design of early stage is only that the seat of standard is mounted on to the side or top of vehicle, so as to
Explosion time occurs and reduces the buckles being directly delivered to occupant, representative is the dynamic suspension seat system of Autoflug company

Due to car weight deficiency, it is difficult to which acceleration brought by blast impulse is decayed to OK range.
To cope with Afghan War, (Jankel) company, letter section, Britain has carried out a large amount of effort in explosion-proof seat design,
And explosion limitation and decaying seating art (Blastech) series explosion seat were finally proposed in 2009, it is filled based on one
" the subtracting squib " of gas and slide runner absorb explosion energy, and " subtracting squib " is reduced to vehicle by shock wave when having been fried can
The level of control.But the adjustment of weight of this explosion-proof seat and resetting are extremely complex, it is difficult to cope with rushing for different explosion equivalents
It hits, and is difficult to reuse and daily maintenance.
Based on same demand and reason, Britain creates (Creation) company and is also proposed explosion-proof seat at the beginning of 2010
Chair, it is main to use and a spring, damper and rubber buffer are imitated to mitigate explosion using constructed of aluminium (mitigate weight)
It answers, but it is difficult to cope with the impact on different explosion directions, the test result in practical explosive test is unsatisfactory.

Make the two generation XYZ VR series seats developed, carry out energy absorption using based on adaptability rheomagnetic technology, can in X, Y and
Z axis provides protection upwards, but the cost of this device is high.
Although numerous production firms have paid very big effort on explosion-proof seat, the American force for being responsible for vehicle production is anti-
Shield Co., Ltd thinks that there is no grasp the feelings that entire vehicle occurs in blast process comprehensively for most of seat manufacturers
Condition, explosion-proof seat are still significantly improved space.
It for army, China, is investigated by the example of the Iran-Iraq war and domestic and international anti-terrorism, on domestic market
There is not also a kind of automotive seat can ensure that vehicle occupant very will not be dead after 5KG equivalent TNT explosive charge.Through
Statistics is crossed, 80% is all the secondary injury as caused by shock wave and then causes death.It can be purchased on existing domestic market
Seat damper be all to be matched with the damping of prevailing roadway, it is difficult to realize thump decay, thus basic nothing
Method meets modern explosion-proof requirement.
There is an urgent need to a kind of seat damping devices for coping with the impact of high equivalent weight explosive charge for China's war industry to answer
To increasingly complicated domestic and international anti-terrorism situation, especially there is independent intellectual property right, be readily produced, manufacture, use, safeguarding simultaneously energy
The seat damping device of the life security of enough effective guarantee officers and men.
