Abstract

An add-on safety harness for a school bus seat having a lap belt. An elongated anchor strap for attaching vertically around a seat back has an adjustable buckle. A first pair of shoulder straps extends at an acute angle from each side of the anchor strap, and ending in a loop. A second pair of leg straps with looped ends extends similarly from each side of the anchor strap. Each shoulder strap has an automatic roll-type adjuster device at a median position. A piece of synthetic lambs'"'"' wool is attached to each adjuster device for wrapping around the adjuster device, being fastened by hook and loop fastening material. The conventional seat belt on the, school bus is threaded through the loops of the shoulder and leg straps. The leg straps can be positioned inside the shoulder harness for small children and outside the shoulder harness for larger children.
