I was in a crash of a plane that had dual shoulder harnesses--better, but
not perfect--they had no cross-over buckle holding the two shoulder straps
together, and my son's shoulders moved back at impact, and he slipped out
of
both harnesses and hit the instrument panel.

David -
The harness design you mention with a cross-over strap is, in racing, called
a sternum strap. I am not a pro racer, but at the amateur level these
devices are NOT permitted as a means of holding a harness around the
shoulders. The harness is required to fit closely on the shoulder without a
sternum strap. That's why racing seats have cut-outs in the seat back to
permit the shoulder harnesses to fit snugger across the shoulders and chest.
I don't know the reason for the rule, just know it exists.
