Abstract
A retractor and boot for limiting passage of dirt and foreign material on the retractor belt. The boot includes a plastic housing surrounding the retractor and has an outwardly extending portion forming a channel through which the belt is movable. A pair of scraping edges are located offset along the longitudinal channel axis and are spaced apart relative to each other a distance less than the belt thickness allowing dirt and foreign material to be scraped from the belt as the belt is retracted.
