Please note: I have received several email comments about this page. What follows is my solution to provide myself with what I believe is an adequate seat belt and shoulder restrain system. I cannot vouch for the system's ability to keep one safe during a mishap, and I do not recommend that anyone use this system.
I replaced the six point belt system with a five point attachment belt system to save weight and to make it easier to get into and out of the belts. The old system required placing four loose ends into a quick release buckle. I got this idea from my grand daughter's car seat. The quick release buckle and inserts are spare parts ordered for that seat. The buckle is much lighter but of sufficient strength to keep me in the seat while passing through strong thermals. Shoulder and waist belt length can be adjusted.
The attachment point for the shoulder belts was moved forward to make the shoulder belts more comfortable. The cable passes through a loop and cable stops are used to keep the cable from sliding from side to side. When the belts are unfastened the bungee cord pulls them up so that they fall to the side of the seat which makes it easier to get in and out of the seat. When in the seat, it is very easy to reach the belt slip it over one shoulder and insert the prong into the buckle. Short pieces of Tygon tubing protect the cable from chaffing on the center tube and the hose clamps that hold the cable retainer in place.
The waist portion of the belt terminates on the side tube just below what was originally the rear seat cross piece and above the lower longeron.
The buckle belt end is attached to the middle front seat cross tube. This arrangement reduced webbing length by about four feet. Also it eliminated two belt length adjusters and about three feet of cable.
Update - November 15, 2003
The retainer for the shoulder belts was removed, rotated 180 degrees and pop riveted to the engine support tube. This arrangement should be a little stronger and saved 1.6 ounces.
