    Itís a Ď53 PA20. With the front and rear heat, the insulation and an O320 it keeps the cabin toasty in the winter even up here in Chicago.

    Iíll take a look. Anything will be better then attaching it to that bench seat frame. What an awful design.

    Steve, I've got a 53 PA22 that I'm installing harnesses in this winter. I also have the rear seat heat and need to figure out where to mount the lap belts. I was going to pull the pans and stare at it a bit come the time, but I would love to hear a recommendation.
    Thanks!
    Ken

    I believe there is a picture of a clamp in this thread to tie the center seat belt mount to the fuselage. Wicks sells structural clamps as well. A strap to raise the seat belt like Piper did in the later models to keep the rears eat heat from damaging the belts as well.

    I would think that if you are installing seat belt attach fittings to the fuselage structure for the center attach point, and you have a rear seat heater, then you should also be complying with AD 60-05-03 by installing seat belt extender part number 14920-02. The attach method can be seen on drawing 14705 section H-H. This drawing doesnít show the extended link, only the original installation.

    Likewise, if you are putting a center seat belt attach in an early PA-22 rear seat, the cross tube on them was only 5/8 X .035. Later PA-22s that came with individual lap belts had 1 1/8 X.049 for the same tube. The 5/8 tube isnít strong enough to hold in a 9G crash! I ran the numbers, and you can use a 1 X .035 just barely meets the requirements. I would strongly suggest replacing that tube!
