2 Part Technique - Slow the opponent's escape with control to give you countering options. Keeping your near leg safe from the Single Leg and forcing the opponent to turn on your terms will secure the Seat Belt in this turtling situation. Use your knee as a wedge against the opponent's elbow to crucifix his arm. The opponent may roll, but maintaining a strong Seat Belt control and continuing the coordination with your legs to crucifix will keep you in a dominant position. Stretch the opponent's arm by opening your knee and lift your hips for the armbar.
