Abstract
The invention provides an explosion-proof passenger seat and belongs to the technical field of vehicles. The explosion-proof passenger seat can be used for allowing a passenger in a vehicle to bear a large acceleration caused by explosion and effectively reducing the impact caused to the passenger by explosion. The explosion-proof passenger seat comprises a lifting ring (1), a lifting strap assembly (2), a seat frame (5), a limiting sliding sleeve (6), a sliding sleeve (7), a power absorber (10) and a pin (11). By adopting a lifting structure, vibration can be effectively reduced and pressure transmission can be prevented, so the sitting comfort degree is increased. The power absorber is mounted on the seat frame, so a part of energy of explosion impact can be effectively absorbed, the impact transmitted to the body of the passenger is ensued to be lower than the tolerance limit of a human body, and the passenger is protected from injuries caused by the explosion impact.
Description
Technical field
The invention belongs to technical field of vehicle, relate to the explosion-proof harness seat of a kind of automotive occupant.
Background technology
Automotive occupant is in the process of executing the task, and the most of the time is all seated, and therefore, the seat that occupant uses has important impact to its factor such as fatigue strength and viability.Along with the increase day by day that exploder (IED) threatens, also sharply increase being in the requirement of shelter of occupant under sitting posture state.When vehicle is subject to the blast wave impact of horizontal or vertical direction, a lot of injures and deaths are not caused because carbody hits, and are more caused by explosion wave.Due to the poor design of a lot of traditional Chinese chair, making finally to be delivered to occupant's shock wave energy with it can, up to more than 5 of actual energy times, threaten usually more serious than blast itself to the injures and deaths that occupant causes.
Western countries have all carried out the research to explosion-proof seat.Its main concept adopts soft suspender belt completely cut off vibratory impulse and design the shock absorber that can absorb impact.At present these explosion-proof seats light-duty the and heavy tactics car race of the country such as American and Britain and anti-immediate action drill vehicle use.
The seat that some vehicles of current China use is be fixed on the rigidity seat not with power-absorbing on base plate.When running into explosive attack, the impact by " knock-on effect " very easily causes occupant's injures and deaths or vertebra major injuries.Along with the lifting to car body equipment protective capacities and viability demand, traditional armchair structure and installation form can not be satisfied with battlefield defense demand.
