SAFETY DEVICE AND HARNESS FOR USE IN SAME ABSTRACT OF THE DISCLOSURE A safety device is disclosed comprising a harness made of flexible sheet, preferably of a strong canvas sheet provided with suitable fasteners and straps for securing the body of an injured person to the flexible base. In one embodiment, the base can be suspended on a pulley-and-rope mechanism secured to the top of an associated ladder. The invention is not limited to the combination including a ladder as the harness can be used with virtually any known suitable lifting device. The flexible harness can be guided along the associated ladder by a rigid U-shaped piece which is secured to the rear of the flexible base of the harness, the guide member being the only rigid portion of the entire harness. The harness and the rope-and-pulley system can be neatly tucked within an envelope near the top of the ladder whereby the contour of the ladder is generally unobstructed and the ladder can be used for purposes other than rescue at times at which there is no emergency, with the rescue harness being ready for a rescue application if necessary. The advance in the art is in the ease of folding the harness into a small space e.g. within a countour of a ladder, while retaining same in operative association with the respective ladder, also securing, by strategically located straps, safe securement of an injured person to the flexible canvas base.
