Several builders here in Florida are installing hard points in various
locations aft in the fuselage. You are right in that the present location
can and has caused spinal compressions. Hard points located against the
roll over structure or back by the baggage bay bulkhead are good locations.
Use a short length of 3/16s aircraft stainless cable with swaged fittings
for the additional length required. If you know the exact length, you can
order the cable with the fittings swaged or take them to a sailboat rigging
shop and they will gladly do it. The tool is very expensive $4000.00 to
swage the fork ends but they do look much better than clevis ends.

Subject: Seat Belt Attachment Route/Spinal Compression
I saw Bob Harrison's message on headrests but has there been any comment or
action on the important issue of lifting the direction of the straps over
the shoulders to avoid compressing the spine in a crash please?

Subject: Seat belt mount points
The seat belts wrap over the seat back and attach near the spar. This does
mount to the strongest point in the airframe, but isn't the best place
ergonomically, as it can cause spinal compression in a crash. It seems to
me that running the straps over a guide bar mounted stoutly to the seatback
but at the right height to bring them straight back from the shoulders,
thence to the existing mount points, would improve things. Has anybody
tried this, or considered this important enough to address?
