IN-VESSEL-EQUIPPED AIRBAG WITHOUT REQUIRING POWER FOR LIFESAVING OF OVERTURNED VESSEL

摘要

Disclosed is an in-vessel-equipped airbag without requiring power for lifesaving of an overturned vessel. The airbag uses compressed air or a chemical reaction rather than an air injection pump and also, is positioned inside a hull without attachment of an additional buoyancy body. Therefore, the airbag of the present invention can greatly assist in securing a rescue time for a marine police when a marine accident occurs, and can delay a sinking time even without a professional diver and a buoyancy body attachment technology. In addition, the airbag of the present invention is different from existing patents in that the air injection pump is not used. Furthermore, the air bag of the present invention is different from a technology used in a vehicle airbag in two aspects of maintaining the volume for a long time after air expansion and having a spatial unit in which the air expansion volume can be expanded from cm^3 to m^3 as a unit.;COPYRIGHT KIPO 2020
