Problems solved by technology

However, during the cushioning process of manned airborne landing, if the airbag cushion seat exhaust hole is too large, it will not be able to effectively cushion and protect the human body, which will easily cause a secondary collision between the human body and the interior of the tank; if the airbag cushion seat exhaust If the hole is too small, it is easy to cause the airbag to burst due to the sharp increase in the internal pressure of the airbag cavity and the slow exhaust speed, which will cause fatal damage to the airborne occupants

Abstract

The invention discloses a working method of an airborne occupant multi-stage airbag cooperative buffer seat. The multi-stage airbag cooperative buffer seat comprises an upper air chamber, a middle airchamber and a lower air chamber; the upper air chamber, the middle air chamber and the lower air chamber are arranged by stacking from top to bottom, the upper air chamber can exhaust to the outsidethrough an upper air chamber exhaust valve for decompression, and can exhaust to the middle air chamber through a combined exhaust valve, and the middle air chamber is expanded to achieve first-stagebuffer; the middle air chamber can exhaust to the outside through a middle air chamber exhaust valve, and can further exhaust to the lower air chamber through a second combined exhaust valve, and thelower air chamber is expanded to achieve secondary buffer; the lower air chamber can exhaust to the outside through a lower air chamber exhaust valve to achieve three-stage buffer; the multi-stage buffer method of the multi-stage airbag cooperative buffer seat can prevent a human body from colliding secondly with the interior of a fighting vehicle, achieve multi-stage release of the internal pressure of the airbag buffer seat, and prevent the airbag buffer seat from blasting, thereby effectively ensuring a safe landing of an airborne occupant.

Description

Technical field [0001] The invention relates to the field of safety protection for manned airborne, in particular to a working method of a multi-stage airbag for airborne occupants in coordination with cushioning seats. Background technique [0002] Manned airborne means that the airborne tank and crew are simultaneously airborne. Since the airborne occupants will bear huge impact loads on the ground at the moment of landing, in order to ensure the safe landing of the airborne occupants, occupant protection devices must be adopted to reduce the impact load on the human body. A lot of practice has shown that a good occupant protection device can greatly reduce occupant injury and reduce mortality. Therefore, the airborne occupant protection device is the top priority of airborne technology research. The airborne occupant safety seat, as an integral protective device, can effectively reduce the damage to the occupants caused by the impact load, and prevent the occupants from coll...
