4Point Harness Installation

[TaHa]

Ok so im looking for help on how I should install my 4 point harness, Looks like this one:

Do I just make holes on back of chair or something? Dont wanna go butchering anything lol.

Cheers

[KIL-06L]

most of the time the 2 shoulder straps go to points on the parcell tray or taxi bar and the 2 lap belts bolt down to the floor beside the seat.

I'm going to need to install a harness in my car as well. Does anyone know if the harness has to have an ADR tag on it to race at ANDRA events? Would putting one in a sedan just consist of hooking the shoulder straps into the parcel shelf and the lap belts to the drivers seat rear mounting bolts?

half this site would need a harness legally.

Hopefully someone can put a full guide on how to install one of these. And also list the ADR approved harness and prices and where from!

Id love one

All belts MUST have ADR tag on them and also be under 5 years old.

There is a date of manufactoring on them and cannot be used after the time elapses in any organised motorsport.

As for the installation, you used to be able to by a ADR compliant bar that ran along the parcel shelf and used the child restraint anchors, but I have not seen one for a long time. If you cannot make them fit in the child restraints, then you would need to have something engineered and approved.

The waist belts use the anchors for the belts. You can (or used) buy a spacer and longer high tensile bolt to allow for both belts to be installed.

As these are primary restraints, they must be installed correctly or you will be defected by the police or banned by a screwtineer at the trace. It could also cost you your life.

You are far better not to fit a harness if you cannot do it correctly, as the regular seatbelt is a better option.

I fully realise that ANDRA has not the personel to check every car and or make amendments to the rules they make. It has to be blanket or it`d bog down

But.. If I hit the wall in my car ( god forbid) its going to be a pillow fight in the cabin.

Sure, if your in a 120Y with a blown 400 chev you need a four point harness by jingo.

But on the other hand a modern car with air bags and selt belt pretensioners is worlds away from some tack welded bucket of sh!t that Bevan and the crue have cobbled together in the back yard.

However food for thought would be that even my stock chunker is doing 120 mph on a good night over the line.

I wanna know what I`m gaining or giving up fitting a four point harness.

When and were will it be policed??

Test and tunes okay? I thought that till we were out there at an ANDRA street meet thingo requiring a day licence and after the car posted a 137mph trap speed a chap in an ANDRA shirt came over and had an informal chat about being 3mph off requiring a parachute. But that was all..

Modern cars and tuning, I would think we need an entire rethink on how things happen at the dragstrip.

I`m thinking I`ll pack it in.

The two times I went to WSID for the off street meet, I had my belts inspected by the screwtineers to make sure they were in good condition.

When he saw that the car only had 2,000km on it he was less detailed. He did make me take out the baby seat in the back that was strapped down with belts.

While your theory may have some basis, any car with a big cage will be more structually secure than a road car, but not always safer. Our kind of cars are designed to crumple in a crash, but not when doing two ton into a concrete wall. A harness and cage would be a far safer option as it holds you better in the straps and the cage will reduce the distortion of the safety cell.

not to mention having a harness in the car looks awesome! :D

ive seen some mounted were the standard back seat belt clip is.. looks way better then to the parcel shelf

Zap, you make very good points. Cage is great IF you are wearing a helmet which at the track you are, on the street its going to get brains on it if you crash. I don`t know how much testing a bit of vinyl covered foam that goes over the bars has been subjected to. A purpose built cage is attached to atleast subframe rail connectors or better, its apart of the entire chassis structure.

A bolt in partial cage? Hmmmmm. It might just meet minimum requirements and little else.

I fully agree its uncharted waters, car manufacturers won`t generally throw a family car at along a concrete wall at 120 mph to simulate whats going to happen at a dragstrip, they`d maintain they build road cars.

Basically I`m saying this ALL needs looking at with an even handed approach.

We all see stuff at the drag strip that leaves us wondering.

Cars are going quicker. Lots of people are attemping to break unofficial records that obviously they are going to be told they can no longer use the car on the track in its current state.

that's pretty hard to legislate against or is it? I wonder that sooner or later they might just attempt that to cover their arse. The 4 point harness is the start.
