You will arm drag your partner then you will use his reaction to come up with your him. If he doesn’t come up you will use your outside leg as a pendulum to come up. When you come up you will put the seat belt, your partner will roll and you will follow him. In this case you missed the time to put the hook but still have the set belt and your partner will be on your side. Your partner will try to put pressure on your chest then you can use the momentum to bridge towards your partner to create space and put the bottom hook then lock over the hip to secure the position, put the top hook and secure the back.
