School me on seat design

[MyRight]

I'm not sure what the designer's intentions are when they come up with the ergonomics for seats.
I'm talking about how the seat contours from lower back up to the head rest.
If you have the seat adjusted so you are utilizing most of it where your body makes contact from lower back up to your head, it is rather uncomfortable and causes your head to bend downward.
If you adjust the seat so it feels most comfortable, only your lower back down is being supported, so your mid back on up is making no contact at all, which make you wonder why there is a head rest if you can't comfortably use it.
I have been using some sort of upper back/neck rest to fill that void area so most of my body is being supported by the seat.

Am I just using my seat incorrectly or what exactly is the deal here?

The seats are horrible compared to JK seats. I took the headrest out, turned it around, and put it back in. That helped my neck a LOT.

IIRC "headrests" which are known by the car industry as head restraints are a safety device and are not intended to have constant contact with your shoulders and head. They are there to protect you from whiplash in the event of a rear end accident.
I was once told they are uncomfortable to not encourage people to use them constantly which would help prevent people from falling asleep while driving. Don't know if that's true.

Adjust the head restraint
The top of it should reach at least as high as the top of your ears and as close as possible to the back of your head. If the restraint can be tilted forward, move it so that it’s no farther than 3 inches from your head; the closer, the better.

Position yourself for a crash
If you see a crash coming—or hear the squeal of tires behind you—and have time to react, lean back so that your head is touching the head restraint and look straight ahead. This will minimize any whiplash effect.

From my understanding of this is it should be safe to use the additional support, as it allows the occupant to already have contact with the head restraint...the recommended position for a crash.
