摘要： An automatic webbing winding device includes: a base; a winding reel mounted on the base and rotatable around a center of the base; a coil spring mounted on the winding reel, one end of the coil spring is fixed to the winding reel, and the other end of the coil spring is fixed to the base; and a webbing mounted on the winding reel, the webbing includes a fixed end and a free end, the fixed end is fixed to the winding reel, and the free end extends out from the base; when the free end is pulled outward by an external force, the winding reel rotates along a forward direction, and the coil spring is elastically deformed, when the external force is removed, the winding reel rotates along a reverse direction under an elastic restoring force of the coil spring, thereby winding the webbing on the winding reel.
