$99 Head and Neck Restraints

[.RJ]

This?

We've built and tested SFI "certifiable" designs at both Wayne State and Delphi, and they exhibit the same flaws as an SFI design, i.e. they lose the belts and you can get stuck in the window on the way out.

Nope not that but this:

2.3
... Direct attachment to react loads to a fixed point or points on a
vehicle structure or restraint webbing will not be acceptable because of the
potential for torso displacements with respect to these points. ...

Same thing That, and the single point of release spec also votes the isaac out for NASA... unless that 2.3 spec infers single point of release, I havent read the whole SFI spec for H&N restraints.
