Colin, Just as a point of reference, my current project's attachment points are as folllows: the seatbelts are attached to, what on a KR would be, the top and bottom spar caps of the rear spar using brackets to span the two structures.
The crotch strap attachment point is forward enough to allow a couple inches between the crotch belt and the jewels. The shoulder harnesses attach to a cable which is bolted to the upper fuselage longerons. This attachment point is the position aft which allows a straight line to the attachment point of the shoulder harnesses themselves. Just thinking out loud here, if your shoulder harness cables are not run in a straight line intersecting at a midpoint between your shoulder blades, in a crash you will be pulled whatever direction opposite of any angle you have in the cable.
