Mounting Harnesses - Quick question

[_Tom]

After edde's post here - http://www.cliosport.net/forum/showthread.php?t=224554

I've decided to decided to take my harnesses off the lower seat belt mounts as it was when i got it. Now if i'm using the upper mounts should it be like -

This

Or this

Or doesnt it really matter?

 

[Renault_Boy01]

either would do i suppose ( but dont blame me if you get injured in a crash )

 

[_Tom]

You sure? lol

I'll do it like the second pic otherwise..

I know nowt about this, but I would have thought that spreading the potential load across two mounting points would be preferable. Are those both seat belt mounting points though, or is one of them a hole that just happens to fit?

Like I said, I know nothing on this but just some thoughts!

would be better to take em off the strut brace.


and yes.they would also be better with a mounting point each........thats why theyd be 4 point harnesses

 

[edde]

The idea of spreading the load is a good one but the mounts are strong enough anyway not to worry realy.

 

[Birdthom]

I thought mounting them on the strut brace was a big no-no as the brace could get moved/bent/broken in a serious accident.

Thats what he is saying the rear strub brace does noting for handing and isn't strong anyway.

i'd put them back down where they were

Nah. The whole reason i searched edde's thread out was because under hard use i could feel pressure on my lower back. With them higher it pulls on my shoulders. More holds you in rather that holds you down.

I need to route mine properly but they look s**t on the upper mounts!
Is there any way of bolting in a brace without welding it in that would be strong enough to use?

 

[Fred@BTM]

as long as the engle of the belts doesn't exceed 45degrees you're fine

 

[benji&eka]

i should think mounting them on the lower bolts would exceed 45deg, i'd put them on the upper mountings they look to be a better angle if a little high but the oe mounting bolts are pull tested for strength anything home made isnt

 

[Fred@BTM]

45 deg is steep!!

 

[C.slicker]

The upper seatbelt mounting points are tested for strength too...?

They can take a force of 70000N IIRC.

[benji&eka]

yes however i will say that the oe belt and seat and mounts are pull tested as a unit as it were
therefore one single item may not able to take that force

 

[benji&eka]

45 deg is steep!!

this is true, i'd just prefer to mount them on the upper bolts imo. but untill anyone bothers to pull test these things (not likely) or has a big crash (more likely) we wont really know

Find a bar which will take IMo least 12 tones of force before any serious deformation and thats ok then again find a bar that strong.

Nah. The whole reason i searched edde's thread out was because under hard use i could feel pressure on my lower back. With them higher it pulls on my shoulders. More holds you in rather that holds you down.

I'm glad someone followed what i said.

After all its aerospace and racing law. I'd expect them to know and research a bit also its UK law for car design.
There a recinet article in track and race car (might be this month) saying about seat belt mounting points only one type of seats is autorised to low mount I forget the name, if this topics still going will try remember to check tomorrow.

So a cage with a bar purposely for harnesses is'nt or is strong enough??

It will be if its well designed.

 

[mini-valver]

I'll look into it when the time comes then!
