An automatic webbing winding device, comprising:

• a base;
• a winding reel mounted on the base and rotatable around a center of the base, the winding reel comprising:
• two protrusion members arranged opposite to each other on a side surface thereof and
• a post located between opposite ends of the two protrusion members;
• a coil spring mounted on the winding reel, wherein one end of the coil spring is fixed to the winding reel, and another end of the coil spring is fixed to the base;
• and
• a webbing mounted on the winding reel, wherein the webbing comprises a fixed end and a free end, the fixed end is fixed to the post of the winding reel, and the free end extends out from the base;
• wherein 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.
