Step 1: Check the D-shaped buckle of the seat belt grip back cushion to ensure that the webbing is not tangled together.

Step 2: Start wearing the seat belt and slide it over your arms to your shoulders. Ensure that all straps are free from tangles and hang freely. The shoulder straps must be kept vertical and not close to the center of the body.

Step 3: Grasp the yellow leg straps with the leg straps and connect them to the buckles on the blue straps on both sides of the buttocks. Thread the excess length of webbing into the adjustment ring.

Step 4: The chest straps are connected together through a buckle with a sleeve. The chest strap must be 15 centimeters below the shoulder. Insert excess length of webbing into the adjustment ring.

Step 5: Adjust the shoulder of the seat belt: Starting from the shoulder, adjust the straps of the entire body to ensure that the height of the leg straps is just below the hips, and the D-ring on the back is located between the two shoulder blades. Legs: Then adjust the leg straps, try doing single leg extension and half squat, adjusting the length of the straps on both sides of the legs to be the same. Chest: The chest straps should be crossed in the middle of the chest and approximately 3 finger widths away from the bottom of the sternum.
