Has anyone considered attaching the lap belt to the seat frame? I guess the
locking pins would become the weak point if you did that, but would the rest
of the structure be strong enough? It would eliminate the need for 3 heavy
attach points that apparantly rip out in a crash anyway. It would also have
the advantage of keeping the same seatbelt tension when you slide your seat.
I am not seriously considering this at this point, but I thought of it as a
way to get the belts around the hydraylic pump between the seats. My other
solution is to have 2 attach points between the seats, instead of one shared
one. They would be about 5 inches appart allowing the belts to go on either
side of the pump. I will have a 4 inch wide tunnel there for my cables, so
if I make the side channels of the tunnel from .032 then I guess It would be
as strong as the standard way with one bracket sandwiched between two .032
channels.
Does someone know in what way the brackets have failed? I.E. did the rivets
shear, or the structure break?
Thanks.

Hi Jesse !

I've never heard of the seat belt attach points breaking in a
Rebel ! .... and there have been a few spectacular crashes -
see the photo archives - Alaska tree cutter ... NO injuries !
Where does this stuff come from ???!!!!

In any case, there's no conflict with the standard belt
setup & the pump for the floats - the belts are clear of the handle
once fastened. The pump is behind the belt attach fitting, and
the handle is well above the floor.

The seat frame is far too awkward to consider as an attach point.
Even if it stood up, the seat brackets that go around the rails,
and the pins, would not be anywhere near as strong as the present
fittings - and you'd still have to adjust the shoulder strap.
