Seat belt bar diameter

[grahamb]

I want to raise the height of the rear seat belt anchor points; is there a minimum diameter/wall thickness of tubing if I elect to run a lateral bar across the base of the rear roll bar mounting points, to use as the anchor?

Found it!

1.3.9. Harness Bars. Minimum dimensions 38mm x
2.5mm or 40mm x 2.0mm. Cold Drawn Seamless
Carbon Steel with minimum tensile strength of
350N/mm. Harness straps may be attached by looping
around the tube or by threaded fixings using inserts as
drawing No. 44 welded into the tubes(s).


So next question, can I just weld brackets on the ends so it bolts to the cage mounting points rather than saddle brackets/welding it to the existing roll cage?
