ABSTRACT:
A life vest having a safety belt harness system. A safety belt of the safety belt harness system is threaded through loops on the life vest and is secured to the vest with a quick release, cam-type buckle. Removably attacheed to the back of the vest is a metal D-ring. The safety harness is threaded through the D-ring. A rope acting as a life line may be attached to the D-ring and then the other end of the rope attached to an object on shore, a helicopter, or to another person during rescue attempts. The rope connected to the D-ring of the life vest will be tensioned, for instance, when a rescuer descends from a helicopter, by the rope, during a rescue attempt. If the person wearing the life vest with the D-ring should get into trouble and need to immediately be detached from the rope to which they are connected, the person can unbuckle the cam-type buckle of the safety strap which, due to the tensioning of the rope connected to the D-ring, will pull the D-ring away from its VELCRO.RTM. connection on the rear of the vest. Since the safety belt has become unbuckled, the free end of the belt will unthread out of the D-ring and the D-ring will be pulled away from the vest leaving only the D-ring attached to the loose end of the rope.
