Also Shoulder belts arent designed for low back seats without head restraints as they caused whiplash thats why the auto industry had to introduce high back seats in all their vehicles in the 70s and many of the earlier Cessnas and light aircraft still have low back seats
Um, not how I'm reading Wiki info:http://en.wikipedia.org/wiki/Head_restraint
They reference forward acceleration loads of the seat structure, not the passenger, as the reason for the head restraint regs.
So, I guess you fly without a seat belt? Do you secure the door tightly?....so as not to be ejected during turbulence?
Kinda makes me think .......of a troll.
