发明名称 Self adjustable harness or sling
摘要 A harness which may be used as a sling to suspend a person from a support in either a sitting or standing position, or may be placed on the shoulder to exert force on a load includes a closed loop of webbing material which is loosely slidable through a pair of D-rings, and a double length of rope, one end of each length being connected to one of the rings with the other ends being provided with a snap-hook arrangement for encircling a support or for attachment to a load. A slider on the double rope can be moved to adjust the overall size of the sling and the webbing is held by the rings in the form of two supporting loops which adjust to the body size. In a modified form, two closed loops of webbing pass through the rings and are double back upon themselves to provide a cradle having as many as four loops to support the back and legs. Another variation uses a single length of webbing for attaching the cradle to a support or to a load to be pulled by the user.
