Seat Harness mounting, following on from 'Race Seats!' thread.. Options

[raz128]

Anyone want to clear this up for me?
I've got a 4point harness on my driver seat and a 3point harness on my passenger seat
When I bought the 3-point harness. The instruction booklet said to mount the tail strap of the harness between 0-45 degrees paralell to the ground which i did on the passenger side.
After doing some research to see if i could confirm it, the Schroth harnesses said the same thing

However i did come across this:
http://www.gforce.com/pdf/harnessinstall.pdf
for those too lazy to read it (or cant run pdf files) it says it's best to mount the tail strap -5 to +30degrees from a horizontal line to shoulder height.

Which is best mount to use? The lower point under the original rear seats or on the C-pillar?
The mounting point on the C-pillar would be within -5 to +30degrees that the pdf file states. but does it satisfy the 0 to +45degree instructions by OMP and Scroth?

not an arguement....its a debate which are fully encouraged..

But you have to realize they are only saying up to 45* is ONLY ok with a roll cage or harness bar
though it is "possible" with approved seat

Most racing seats are not designed and tested to carry shoulder belt crash loads from downward installation. Severe injury or death could result. A 45° downward shoulder belt installation is possible with seats that SCHROTH has positively tested to take a load measured during a 50 kph [31 mph] and 28 G impact with a 75 kg (175 lb) dummy.

but not really recommended
but not only is your angles of dispute but your mounting distance and other factors are off as well
just make sure you're also reading the shoulder belt info and not the lap belt info were they work between 45* and 55* :lmao:

but hey...its not my spine (thank god) i'll never ride in your cars!

all quotes/pictures and data are taken from SCHROTH's website and manual

harness bar you need to have custom made. basically look at what sparco produces and replicate lol
