Metal to metal seat belts securely mounted (driver and passenger) 4-POINT harnesses not meeting DOT FMVSS 209 ARE NOT PERMITTED.
5-POINT OR 6-POINT SAFETY HARNESS MAY NOT BE USED WITH STOCK
SEAT UNLESS PASSED BY TECH INSPECTION. The installation of non-factory restraint systems must meet
Manufacturers Safety Specificaions. ON VEHICLES IN WHICH A PASSENGER MAY BE CARRIED (ie:
STUDENTS REQUIRING INSTRUCTORS OR INSTRUCTORS CARRYING STUDENTS), THE DRIVER AND
PASSENGER SEATS AND RESTRAINT SYSTEMS MUST BE MATCHING.
7. SEAT BELTS / SAFETY HARNESSES: Both driver and passenger must have the same level of
protection in both belts and seats. Harness guide bars must not be used as anchor points for belts. All
harness systems must include a properly secured antisubmarine strap, must be used with a seat having
appropriate routing holes, and should be used in conjunction with properly padded roll bar or cage.
Shoulder strap angle must be no more than 40 deg. from horizontal. No 4-point harnesses allowed.
All cars running with open tops MUST have full harnesses and arm restraints.
No mention of 4pt on their tech form, skips from 3point factory to 5/6 point race setup in conjunction with rollbar/cage, 4pt prob not allowed here either
So how does it work when the website http://www.hmsmotorsport.com/
says it does meet FMVSS209? Will NASA have to let it be used?
This is from the website:
"The difference between Quick Fit and Quick Fit Pro? Quick Fit Pro harnesses have a different geometry and use a central cam lock which allows for use of the HANS device, where the standard Quick Fit is more of a standard 4 point shape using a typical buckle. Both are legal for road use in the USA, conforming to FMVSS209 which regulates primary vehicle restraints
