can i use my c piller bar for my harness bar i have a 97 ek hatch and the em racing auto x pkg. and i was going to purches a takata harness long version.
would this work and would it be safe?
i didnt know if it was the right forum sorry if it iis wrong

wouldn't be safe if you were in any sort of collision at speed. you'd probably shear that bar in half, if you don't rip the mounts out of the c-pillar.

i wouldn't do it for a race car--but shadier harness setups are often seen at auto-x's. I don't advocate it...

why not attach the high belts to the rear seat belt mount?

 

get a sparco harness mount bar
its BLING

expensive though

 

high belts to the rear seat belt mount
how would i do that
and is that safer
like this?

 

zorro!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

no **** right.......that just looks rediculous.

 

in an accident, having the seatbelt like it is pictured above will cause you to do very bad things to your spine.

lol it was meant that way.

 

its not safe.

consider the amount of force and stress it needs to withstand for it to work properly, pillar bars arent designed for shear loads.

however, if its SOLELY used for autox for the main purpose of keeping you in your seat, and not for any situation where high speed accident can occur (street or on a race track), then i personally dont see a problem with it. the risk of any safety issue is so low during an autox, its not a concern.

Your reasoning to get one is "its bling"? Wtf is wrong with you. Not like that bars any better, now the car flips, and you're strapped snug in your seat, upright as the roof crushes into your skull and compresses your spine...

 

If you are going harnesses, get a roll cage. It is actually less safe to have a harness with no roll cage. You can't move or duck yourself if you have harnesses.

 

I have always been under the impression that the rear seatbelt mounting points are where the "long" takata harnesses are designed to be attached. I remember seeing some track cars with this setup...

Looks good as long as you have proper roll-over protection...

IM ONLY AUTO crossing and daily driving would that be ok if i were just to do that setup with the rear seatbelt mounts.
if i were to get in a car crash is that like a automatic death if i do have the harness like that. i dont plain on flipping over or major track racing. would this be ok or you guyys wouldent sugest this?

 

again, dont daily drive it attached to the c pillar bars.

keep your regular seat belts and seats. just use the harness for autox.

 

yea i have the jdm recaros so i was thinking a harness bar would deff be good improvement for autocrossing. but if i keep my stock seatbelt i guess ill just use that for road use. but how would i be able to use it for daily driving harness bar or is it possible to use the rear seat belt mounts

 

you seem really set on using your harness for the street.

why?

 

idk i guess i just dont want to switch back and forth with them
and i like the feel of harness compared to the regular seat belt

 

If you do NOT have at least a roll-bar or roll-cage, then you should ONLY use the harness for Auto-X (no track or street driving). If you do have a roll-bar or cage, it may be okay for street driving, but you will have to make sure your head cannot come into contact with any of the tubing no matter what (padding doesn't help)...

 

DO NOT USE THE C-PILLAR BAR FOR MOUNTING SEATBELTS YOU WILL DIE IF YOU CRASH!!!!!!!!!!!!!

I'm not sure how that passed NASA tech ( ) but mounting harnesses that low relative to your shoulders leaves you prone to spinal compression injuries. Every harness maker generally supplies you with a chart of acceptable angles at which the rear harnesses should be mounted at. they tend to be along the lines of 5 degress below parallel (to the ground) or 22 above. those aren't exact #'s, but should be in the neighborhood.

what happens is that in an accident, as your body moves upward, the seatbelts, if mounted at that extreme of an angle, catch the upward movement, but the momentum of your body mass crushes your spine due to the intense axial load.

bad monkey the angle does kind of look extreme but IIRC the took messurments and it was right on the line of being legal.

BTW tons of cars that run under the FIA rules have there harnesses setup in a similiar manner. I asked some one who works on FIA groupN ( i think) race cars, about the harness. he said that some people run it like the fit others attach it to a special part of the roll cage.

IMO the fit cage was designed around minimulist standards and used what i seem to think is the "old way" of mounting a harness.

Interesting point, alot of production based race cars run very long belts, they do this becuase the belt strechs more sense there is more there.

i can understand the need to keep weights as minimal as possible, but it seems like welding in a harness bar to that cage would have added a couple of lbs at the most?

yeah, i think a sideview shot is needed to see how much the belts angle down.

i wonder what the free body diagram of a body in a collision is like, in analyzing belt stretch, spinal compression, and the millions of other forces at play?

I can't answer your first question for them, but for me and cars i drive, saftey is #1.

I think it would be interesting to see a comparision between say, a Willians short belt 6 point, and a willians long belt 6 point done on a sled.

I have heard people scauf at the long belt design becuase they say with short belts your body already moves around A TON. and after seeing 3 or 4 in car video's, i know this to be true. I have also seen how a window nets, and passanger side nets could be usefull, contrary to what some people say.

 

I wouldn't use a harness without at least a roll bar. If you flip and the roof gets crushed, you'll be strapped into your seat. There will be nowhere for you to go and you neck, spine, etc will be crushed. Quite dangerous.
