Reclining Front seats

[PercyJ]

Does anyone have any complaints about how far the front seats recline? I recently drove up to NYC from Charlotte and my first "long blink" was my que to pull over into the rest stop and take short nap. As I tilted the seats back to stretch out, I was surprised to see that the seats stopped at about a 45 degree angle. On any car that i've owned, I have been able to get the seat down as far enough to get the headrest touch the rear seat.
Does anyone know of a way to get that seat to lean back farther than it does currently?

Thanks in advance!
