Abstract

A life vest or preserver for a person who has encountered an emergency at sea or over some other body of water. The life preserver is provided with an inflatable lifesaving collar. Provided on the life preserver, around the armholes as well about the entire lower edge, are pocket-like containers that can be closed. Arm and leg coverings are removably secured in the pocket-like containers in such a way that those parts of the arm and leg coverings that are removed from the containers can, as a protective covering, be placed about the hands, arms, feet, legs, and abdomen of the wearer, with each of these parts being provided with a zipper. Formed preferably in the foot portions of the leg coverings are slits, each of which is provided over its entire length with a closure that opens automatically under compressive load.
