Problems solved by technology
Existing life jackets have a single function, cannot prevent and reduce the above damage, and only play the role of a life buoy
At present, some aircrafts use fixed airbags installed on the seat backs similar to automobile airbags, which can only buffer the impact of external force on the head of passengers in one direction, but the direction of external force suffered by passengers in an aircraft crash may be omnidirectional. Yes, so the effect of this airbag is limited
[0003] In addition, when a fire breaks out in a building, most of the people in the building do not have escape protection equipment when escaping, or only have escape equipment with a single function. Injuries caused by falls in the rush to escape, resulting in a large number of casualties

The invention relates to a multifunctional life vest with rapid wearing, impact resistant, and smoke and poisonous gas resistant functions. The multifunctional life vest is technically characterized by comprising a head air bag set, a nick, shoulder, back and spine integrated air bag, a chest and abdomen part multi-level protective air bag set, a closed type head cover and air purifier, connectingpipelines between air bags with single-way air valves, connecting and fixing belts between air bags and an inflating device. The inflating device is connected with the head air bag set, the neck, shoulder, back and spine integrated air bag, and the chest and abdomen part multi-level protective air bag set through the connecting pipelines between the air bags with the single-way air valves, and the air bags are inflated by the inflating device. The top end of the closed type head cover and the air purifier is connected with the head air bag set, and the neck, shoulder, back and spine integrated air bag is connected with the chest and abdomen part multi-level air bag set through the connecting and fixing belts between the air bags. The multifunctional life vest can effectively buffer and protect damage of external force from different directions to important parts of a human body, has multiple functions of fire resistance, smoke and poisonous gas resistance and the like, and has the characteristics of being convenient to carry and use, simple and rapid to wear and the like.
Description
technical field [0001] The invention belongs to the technical field of lifejackets, in particular to a multifunctional lifejacket with the functions of fast wearing, impact resistance and smoke, dust and poison gas prevention. Background technique [0002] In the process of emergency landing due to aircraft failure, passengers and personnel were injured or killed due to violent collision and burning of the cabin. The causes of fatal casualties are mainly concentrated in: open and closed craniocerebral injury, cervical and thoracic vertebral body and spinal cord injury, closed chest injury, abdominal organ rupture, fracture, crush injury, burn injury, asphyxiation by inhalation of toxic fumes, etc. The existing lifejacket has a single effect, cannot prevent and alleviate the above damage, and only plays the role of a lifebuoy. At present, some aircrafts use fixed airbags installed on the seat backs similar to automobile airbags, which can only buffer the impact of external f...
