The invention provides a safety belt tensioning method applied to a safety belt. The safety belt comprises an outer fabric layer and an inner cushion layer. The inner cushion layer of the safety belt is filled with a safety airbag. The edge of the outer fabric layer is set in a tear structure which is closed by sewing. The method includes the steps of using pressure sensors arranged on the periphery of a frame to test vehicle collision pressure and output pressure signals; using analog-digital converters to convert the pressure signals into digital signals; using the electric reel to tension the safety belt; using a controller to receive the pressure signals, controlling the safety airbag in the inner cushion layer to start up when the pressure signals reach a preset value, and controlling the electric reel to tension the safety belt.
