the geometry to avoid compression looks good. However I think the plate
will get a strong bending load in a crash like mine. Think of a 40G load
pulling forwards at the top of the plate. 40 times the weight of your upper
body.
If the plate was straight and attached at the front of the headrest
structure it would see more compression and less bending. Putting a flange
on the edges would help to give more strength in compression too.
I try and think in terms of pin joints at all the corners and attach
points, then everything has to be in compression or tension.
