harness pic request

[tomti]

can i see some pics of your harnesses and how they are attched at the back please? ive just got some 3 point harnesses and not sure if i screw the eye bolts into the old rear seat belt mounting holes as they are not centred directly behind the front seats if that makes sense or doesn't it matter?

thanks

you will want them as close to parralel as possible.

tbh, if your running harness'/buckets, you need a cage, then you can attach harness' to that.

[tomti]

yea i know but cant afford a cage just yet. When i get one i'll get a harness bar on it. Till then im just using the eyebolts that came supplied with the harnesses

I would recomment that they are no more than 10 degrees from the centreline of your seat so going to the anchor points might possibly be a no no.

I wouldn't drop them more than 45 degrees either as that too will have serious consequences in the even of a crash.

Can you afford the stay in hospital after you roll the car and the bucket seat and harness keep your head propped upright while the roof stoves in on your head?

If you don't have a cage then use a 3-point belt. Once you get your cage, then fit your harness.

[tomti]

with all due respect, rather than preaching at me, has anyone got any actual pictures i could see like i asked for originally?

Pointless thinking that a 3 pointer will save you in a bucket seat. Try moving your shoulders out of a well fitting bucket seat with a 3point belt when it's locked the reel. Almost impossible.
You have to weigh up the benefits of a harness in a non rollover accident against the negatives presented in a rollover accident and then make your choice.

I would post up the pictures of my 4 point mounts but doubtless i'd be ripped to bits by the experts for some tiny imperfection.

As per the 'Blue Book'
The anchorage points to the rear should be positioned so
that the strap from the shoulder is as near horizontal as
possible. It should not be located on the floor directly
behind the Driver/Co-Driver.

So, in an ideal world, fix the harness to custom made bars, or the rear bulkhead / parcel shelf (suitably beefed up and re-inforced).
In your current real world, use the rear seat belt mounting points a lot of racers use this mounting point and AFAIK have no issues, either with the scrutineers or in use.
And yes, in an ideal world, get a cage as well, but anyone who thinks that in a violent rollover they're going to have the time / strength to duck down under the seat AND STAY THERE is very much mistaken. 'Soft' rollover a different issue, but this doesn't often result in caved in roof - tried both, prefer the latter (assuming you've got to do one or the other!!)

Wasn't saying that Kim - apologies if it sounded that way. My point is simply that the seat and harness will keep the occupant upright and at risk of impacting the roof in the event of a severe roll-over. Without the bucket seat and harness the occupant will no doubt be injured, but at least will not be held rigidly in place. As the roof stoves in the head, neck and torso will be displaced by the roof. In a bucket seat with harness (without a cage) there is the risk of damage to the upper vertebrae as the head is pushed down into the torso, where the torso is held in place by the bucket and harness.

Sorry Tomti, not preaching, these are just the facts. Do a search on this forum, you'll see the issue of fitting buckets with a harness with a cage comes up regularly.

GeoffBob i know these are the facts. ok your not preaching but i know all whats been said.

All i asked for was a couple of pictures so i could check something but it seems that whenever someone posts something on these forums, it always gets taken off topic and you start getting told you can/can't or should/shouldn't do this/that!

This is not aimed directly at you geoffbob by any means its just a general thing that a lot of people are guilty of.

What ever happened to getting a straight answer when you want one???

you asked two questions one of which was answered in a manner that cared about your well being. it has not gone off topic at all.

as for your first question you are not likely to find many pictures of harnesses bolted up the way you asked as most people are wise enough or told by others not to do it that way.

Spot on. Why ask for something which is not recommended then ignore the advice given? In my mind, in order of priority (assuming track use) is:

• Helmet
• Cage
• Harness

Oh, and driver ability [/list]

Here's my Touring, as used at Llandow and Cadwell this year.

This pic is probably the most useful to you :


The rear strap is just about MSA-compliant, being less than 45 degrees from horizontal, but I wanted it for better control more that for enhanced safety.
