His breathing is like that because he likely has a collapsed right lung. Most likely the right lung's pleural space is exposed to the environment, which means his lungs isn't sealed within a pleural cavity... That means that he can't generate any "negative," pressure... That means the lung collapsed.
That's what happens when you have a collapsed lung. How breathing is just fine... For having one working lung.

Not "How."
Also this was no seatbelt. Most likely a machine of some sort chewed him up. The world may never know
