Abstract: An occupant restraint system for use in vehicles wherein at least a portion of the restraint system is visible at night. This permits observing compliance with governing safety laws and principles. The restraint system specifically utilizes a material in association with restraint belts that becomes illuminated such that the belts are readily visible. The material that provides the visibility is material applied to, or made a part of, the restraint belt, particularly a portion of the shoulder harness portion thereof. Materials that include reflective substances, phosphorescent substances and/or fluorescent substances are utilized. Further, fiber optic elements can be incorporated that are illuminated from a light source.
