Saab, yes. My point was about the importance of a properly adjusted harness, rather than to suggest harnesses per ce are often a bad thing. No doubt there's a case somewhere where the presence of a properly set-up harness killed somebody, but I don't know of it.
There's also been a couple of cases in tandem microlights where the lack of a shoulder harness in the rear seat caused the passenger's body to break the pilot's neck.
