Abstract: A guiding device for a seat belt system has a guiding ring, a moving seat, and an elastic member. The moving seat is slidably mounted on the guiding ring and is moveable upward and downward. The elastic member is connected between the guiding ring and the moving seat for providing an elastic force to the moving seat. When a webbing of the seat belt system is pulled, the moving seat is pulled by the webbing and moves downwardly. The elastic member is stretched to generate a cushioning resilience to reduce the pulling force. The structure of the guiding device is compact, so the guiding device is low-cost in manufacture and small in volume without occupying much space.
