Background

The armored vehicle is a general name of tanks, infantry combat vehicles, armored personnel transport vehicles, armored reconnaissance vehicles, armored engineering security vehicles and various armored self-propelled weapons, and is a military vehicle provided with weapons and provided with protective armors. The state of the art of protection for modern armored vehicles is increasing, but the data obtained from foreign battlefields, practice exercises and peace and missions shows that casualties caused by anti-vehicle mines or simple explosives are still on the rise.

Analysis shows that when the armored vehicle is attacked, a plurality of casualty accidents are not caused by breakdown of armor, but are caused by explosion impact energy transmitted to human bodies through structures such as vehicles, seats and the like. If the seat structure is poorly designed, the shock wave energy finally transmitted to the passengers can be 20-30 times as high as the human tolerance limit, the casualty threat to the passengers is generally more serious than the explosion, and serious casualty accidents such as human vertebra fracture and the like are easily caused.

Therefore, in order to reduce the injury to the passengers in the vehicle, a special lightning protection seat needs to be installed in the vehicle. As in chinese patent [ application number: 201220070716.5; authorization notice number: CN202439585U discloses a hang seat with lightning protection function, including the mount of fixing on the automobile body and the seatpad bracing piece that articulates on the mount, the cladding has the seatpad cloth body on the seatpad bracing piece, links to each other with the seatpad cloth body and is equipped with the back cloth body, and the both sides of back pad cloth body link to each other with the seatpad cloth body respectively and are equipped with the connecting band that hangs the back pad cloth body fixedly, the other end of connecting band extends to seatpad bracing piece department and links firmly on foretell seatpad cloth body. The seat has the advantages of light weight, convenient disassembly, good lightning and explosion protection effects and the like.

However, the above-mentioned suspension seat has the following drawbacks, and specifically, when the above-mentioned suspension seat is installed on an armored vehicle for use, there are two tactical requirements, one is that the connecting belt is hung on the vehicle, so that the seat cushion can be hung for use to buffer the explosion impact, but because the seat cushion of the above-mentioned suspension seat is hung and fixed by the connecting belts at both sides, that is, the seat cushion is hung by two hanging points during the use, the weight of the seat cushion is completely supported on the connecting belt, and it is found through the use that the seat cushion is easy to shake up and down sharply in a large range during the explosion impact, so that the seat cushion of the seat is not stable enough during the explosion impact, even the connecting belt is disconnected to cause the seat to fail after the explosion, and the safety of passengers cannot be effectively ensured; the other is that according to the combat requirement, the soldier needs to quickly transfer at the front side and the rear side of the seat, namely, the soldier needs to pass through the seat backrest, at the moment, the soldier needs to firstly unfasten the hook of the connecting band and take down the connecting band for avoiding, when the connecting band is taken down, the seat cushion is hinged on the fixing frame and reset through the torsion spring, and the seat cushion can not be in associated locking, at the moment, the seat cushion can upwards rotate and erect under the elastic action of the torsion spring and is in an upwards erecting state, the soldier needs to cross the erected seat cushion to finish passing through, so that the passing difficulty of the soldier is greatly increased, the soldier can not quickly fall according to the tactical requirement, and the combat efficiency is seriously influenced; therefore, the suspension seat is difficult to meet the use requirements of two tactical states;

in addition, in the suspended seat, in order to meet the requirement of explosion impact resistance, the seat cushion consists of the seat cushion supporting rod and the flexible seat cushion cloth body, so that the explosion energy received by the seat cushion can be buffered and absorbed, and the safety of soldiers is protected, however, no support is arranged in the middle of the seat cushion supporting rod, so that when the soldiers sit on the seat cushion, the seat cushion cloth body easily sinks, the supporting strength of the seat cushion structure is insufficient, the seat cushion structure is not reliable in use, the buttocks of the soldiers cannot be effectively supported, and even under severe explosion impact, the seat cushion cloth body can be torn, so that the safety of the soldiers is not guaranteed; meanwhile, as the notch in the suspension seat is designed at the middle upper part of the backrest cloth body, when a soldier sits on the seat, the neck and the back of the soldier cannot be supported by the backrest cloth body, so that the soldier is not comfortable when sitting; meanwhile, a space is reserved between the back surface of the backrest cloth body and the vehicle body, so that the soldier is not supported enough on the back when riding, and is difficult and uncomfortable to ride; in addition, when the seat is in a fighting environment and shakes violently, the neck and the back of the soldier cannot be supported sufficiently, so that the safety of the soldier is not enough when the soldier sits.
