摘要: There is provided a winding spring for a seat belt winding apparatus which comprises an output drum and a take-up drum. The winding spring is stretched in the S-shaped form between the output drum and take-up drum. In the normal use region of the entire length of the winding spring, the natural radius of curvature of the spring is gradually increased. In the surplus use region of the spring, the natural radius of curvature of the spring is divided into a part where it is gradually decreased and a part where it is kept constant. The natural radius of curvature in the free end portion of the winding spring is increased.
