A life parachute including a canopy formed of pieces of fabric sewed together, sheaths extending from the center of the canopy in a spoke-wise manner, and an inflatable envelope connected to a compressed gas container by way of a conduit. The inflatable envelope has a main body in the center thereof and legs extending spoke-wisely from the periphery of the main body; the legs and the main body are interconnected and inflatable. The number of legs is equal to that of the sheaths. The free ends of the legs are inserted into the corresponding sheaths and then secured onto the canopy so that the main body of the inflatable envelope can be maintained at the central portion of the canopy.
