Patent number: 6974610Abstract: A roll stock of a graphic transfer strip for use in making a high visibility safety garment for wearing by an individual exposed to a higher than normal risk of injury from vehicular traffic. The safety garment complies with the visibility requirements of a published standard such as the American National Standards Institute for High Visibility Safety Apparel. The safety garment has one or more high visibility safety stripes that encircle the torso. The safety stripe is formed of a plurality of separate but closely spaced stripe segments in a generally repetitive pattern that is substantially continuous for the length of the stripe. The stripe segments are formed of a retroreflective material. The stripe segments occupy a portion of the total area of the stripe sufficient to impart to the stripe a coefficient of retroreflectivity that meets or exceeds that required by the standard being addressed for the safety garment.Type: GrantFiled: December 10, 2004Date of Patent: December 13, 2005Assignee: Safe Reflections, Inc.Inventor: Robert D.
