Seat belt anchorage points & Rollbars

[bzrse7en]

Hi
I'm building a space framed car and it will at some stage, in the future have a MSNZ logbook.

I want to use the Harness bar to anchor the harnesses as it is the best possible place. The roll bar is built to MSNZ scheduled A using correct materials and TIG welded.
In the Hobby car manual, it talks of having tube intersections near the anchorage points when building a space frame. When using a harness bar, this isn't really possible, or necessary, as the material specs are superior to the furniture tube the rest of the chassis is made from.
So, will a roll bar built to scheduled A suffice as a seat belt anchorage point? Or will my Certifier grumble and want extra unnecessary tubes added?

Thanks
Patrick

A roll bar meeting MSNZ Schedule A will be fine as a harness attachment point.

The material of the roll bar will be considerably stronger than that of the typical spaceframe material.
