Beschreibung
Zusammenfassung:	The utility model discloses a back cushion capable of converting into a buoyancy life preserver in water, which comprises a first back cushion (20); a detachable second back cushion (10) is disposed at the edge of the outer periphery of the first back cushion (20); when the back cushion is used as a life preserver in water, the second back cushion (10) can deform into a buoyancy life preserver for lifesaving in water; the second back cushion (10) adopts an inflatable lifesaving structure, or a lifesaving structure with buoyancy materials filled in the second back cushion (10); sufficient buoyancy is generated by the second back cushion (10) in water, which can at least make a head of a person in water expose outside the water surface safely. Therefore, people are better helped to timely convert the back cushion on the seat into a buoyancy life preserver in water immediately after escaping from a vehicle in time, and people are timely escaped more safely in water so as not to be drowned.
