Five Point Seat Belts and Reclining Seats for the Kids

Protection is priority number one when it comes to seat belts.  However, watching my young children fall asleep in the back with their necks crooked over and faces smooshed into the window I have to think there's a better way to do it.  What if you could have five point seat-belts (like the ones little babies and race car drivers wear) and then recline the seat?  The real question is would a five point seat belt offer the same protection if you kid is lying down.  Then the parent could have a button for each seat and when they notice one of the kids drifting off you could hit the button and recline their seat.
