You the man,Brady !!!

All right, here's what i got. These are 5/16'' steel. They should last forever. I need input on what you think. Is the loop in a good position. How much room is between the seat and side. We don't them to hit anything. I figure if these don't go past the seat hinges on the bottom. They should be fine. I don't have a car to check. I can make this loop closer to the headrest if desired. Just let me know. I know a couple people wanted them to the side. There's no way the seat will come out of this. If this is what you all want, as soon as you give me the feedback, I'll make them. Same price as before.
I also can put it either in front or in back of the headrest which would move it about 1/2 inch forward. Specify placement.

Now you're talking! I like the way you've got it swept down slightly, it gives it a good look and appears to be in a better position.

I need to know if you guys want these. I'm not going to make them if your not interested. PM me.

Do you have a price figured out yet?

Hi Ron,
It would be the same price as before mentioned. $50 + shipping. It takes time to heat and shape these things.
If anyone likes the first design and would like them, just let me know when you PM me.

Please understand I can make these either sit infront of the headrest or behind it. I need to know which way you would like it. If not mentioned, I will just place it behind the headrest. Thx.

I have mine on order...as usual the 82's lead the pack!
Craig
ps ..Brady behind the headrest for mine,I am already used to it being there.

Hi Craig,
The cheapest shipping is about $11 at the P.O. They wouldn't fit in the $5 box. I have your set done.

Hi all... I had a little time to waste... here is what I came up with on my CAD system, I amn going to check what tooling costs will be for a billet aluminum with anodized finish in various colors. Getting quotes soon for production costs and lead times.





What do you think?

It looks nice! I was thinking of making the inside of my first design something like that. But then I thought, that is the area where the seat belt will have the most tension. It could pinch the clip or maybe even come out.

Thanks... I think you are right about the belt getting loose, I just changed the design to allow the seat belt to install via the outer portion but the seat belt must be easily removed for safety purposes, of all the convertible car seat belts design I've look at they provide a way of getting the seat belt off quickly for access.

For loads I can assume a 250 LB person at 3g's in an accident and the clip could not go plastic and bend/break all the loads on the clip will be transferred to the headrest rods (2)... will model this on my ANSYS stress program an come up with some numbers...

Guys - I hate to interefere with all your fun, but I have a concern. The stock plastic guide is only a guide - it is not load-bearing. The person's shoulder should be the load-bearing device, as it is for a HANS device. And, the stock guide is open on the inside end, so the belt can move towards the headrest if required to properly fit over the shoulder. If you build it out of steel or aluminum with the opening on the outside and it fails to protect the occupant, who will be liable in the event of a serious injury? Sorry to be a wet blanket, but I'm concerned about safety more than aesthetics.

I understand the safety aspect, the original plastic design was made to be open in the center to remove the belt easily, for saftey and or access, the load in an accident would put most of the load on to the seatbelt bracket and the top of the seat, hopefully if the seatbelt retract/rachet mechanism is working (not binding) the seatbelt should rachet and lock. The seatbelt guide would see some of these loads but not much either way the seatbelt guide will twist but by how much... this we will know soon.
