To clarify this procedure:
- Lean the seat back, and get in the back seat.
- Push the button on the side of the headrest and raise it all the way up.
- Unscrew the plastic flanges about 1/2 turn - then slide them up their leg, and use tape to hold them out of the way.
- About 1/4 down inside the seat material, toward the front and on the drivers side of each leg, you will find a metal loop - about 1/8" diameter. This is the head of a spring that holds the leg in place. Put a skinny screwdriver into the hole, and move it around the leg and back toward you 1/4 rotation or so. This releases that leg, and you can rock the headrest up on that side to keep it from going back down in. Release the other leg the same way, and with both of them slightly up in the hole, you can now move the whole headrest up and out.
- To straighten the bend in the legs, I used a machinists vise, and almost flattened the bend completely, to move the headrest back away from my head a bit.
- Replace the headrest by sliding the legs back into the holes - the springs will lock them in. Screw the plastic flanges back in place.
- Enjoy sitting upright without having your head pushed forward.
