Post subject:  Retractable seatbelt fitment

I'm about to install a pair in my 63 mini and was wondering where to mount the spool.
My best guess is in the rear bin but what side do I mount it on (front or side) and I was thinking of running the belt through the ash-tray hole but are the edges to sharp and how would I smoothen them out?
If you've fitted these in your mini can you post some pics please.

I did this a couple of weeks ago. I used the normal mounting points and put a spacer on a longer attaching bolt so the webbing wouldn't get stuck or rub below the door. You can see the spacer in the 3rd pic. My England doesn't allow me to explain the whole job properly and it's hard to see in the photos. Also the reel will hit the seat if you sit too far back. But I'm 177 high and don't have a problem though. If you want any more or better pics I can take them.

Get the correct Klippan belts and they come with the bracket required to mount them as per picture.

I would not recommend drilling new holes in the rear storage bin as it is not legal without being engineered and probably unsafe too.

Where do I get Klippan inertia reel belts for the Mini in Oz?

OK guys, now about my commission...

I got mine from the local auto accessories shop. Around $100 each. I think they could have been model 1512, but don't quote me on that. You can do a search on this website for "seatbelts" to find more pictures and info.

I'm going to ignore what you said Anto because I've already fitted them :D
I'll post some pics asap as photobucket is down for maintance now :x
I have the highback Clubman seats and I could'nt see how to fit the reel on the orgional lower bolt hole without fouling on the seat. I'm happy and confident about where I bolted them as from memory I've seen them in a simular postion on other cars. Also the Rovers have theirs mounted in the bin somewhere :? Thanks everyone for your help though.

Try http://www.minisport.com.au/ thats where I got mine from I paid $180 but I also spent $5330 so I may of had a discount :wink:

Hay WantOne those are the exact same ones as I got but with your instaltion is it hard to get in the bact without catching the belt on your foot? and I like were your speaker is 8)

It doesn't matter where you mount them, but the mounting point MUST be reinforced, and if it's not where the factory put it you'll need to have it signed off by an engineer.

This isn't just for the pencil pushers, but for your own safety. The very last thing you want in an accident is the seatbelts ripping out of their mounts and casting you into the windscreen...

I would NOT mount them in the rear bins. You will tear the bins off the floor should you hit anything. Our Barney had `em in the bins, I took them out... and went back to static belts because the early Clubby seats in the car foul the reel if mounted under the doors.
Late Clubbies have an additional mount added to the inner sill where the reel mounts, all roundnoses do not have this.

Another thing- a `63 Mini has a weaker upper mount than late cars. I'd not use retractables because it doubles the load on the top mount, as has been discussed here in previous posts this year. By various engineers, including me.

mounting them with a spacer seems a bit dodgy, in the event of a crash with lots of force placed on the belts would cause the retracting part to pull hard on that bolt, and because its away from the body and not solid mounted on it it wouldnt be half as strong.

Yeah that makes sense, but when I can post the pics it should show that the seatbelt brackets do reinforce the mounting point.
I'm planing an appointment to the engineers one day as I'm also going to install 7.5" S disc brakes and negative camber units etc etc so I'll get it all done at once.

I agree BUT, I think they are still a step up from the sun faded POS seatbelts that came with it, and the factory fitted 1960's ones most people still have fitted to maintain originality. I'm still working on a better arrangement. Luckily I work at a place that has the best fabrication workshop in Adelaide so will get around to manufacturing a larger load bearing plate to fit on the retractor unit. The car is in the garage most days not a daily driver, so I'm not that fussed at the moment about it.

Kennomini: The speakers weren't my idea, they came with the car, but I agree they are a good idea. Nice and neat and nothing has been cut which would weaken the body shell in the event of an accident.

As for the back seat passengers, I haven't had any in about 6 months because there are no belts in there. But the doors open wide enough, and the seats go all the way forward so people don't find it too hard to get in.

Hehe...I love this topic. Next thing to happen is someone (like me) asks how the force at a particular point in a closed system can double while the overall force somehow stays the same, and then people start arguing with bad science, and it's great! :lol:

It's just snatch block mechanics technology. The top mount in a retractable system acts as a pulley. As old as the hills, older than me even. :lol:
Ask any woodcutter or serious offroad 4WD enthusiast. :wink:

Got some pics for scrutineering, enjoy

To try and explain my reasoning "I've did a drawing thats heaps good" :oops: Just trying to show that the seatbelt brackets act as the reinforcement.^^^
Image
The 2nd shot shows it the best that the anchor point is as close to the B pillar as possible

This one is just showing how I'm protecting the belt from the sharp edge of the ash-tray. note colour coded pegs to make it blend in :wink: almost professional wouldn't you say :lol: .
I know that a "pulley" dose increase the forces but I doubt that it can double them, me and my regular passengers weigh in between 45-65kg so if the std top mount can't support those forces even if their doubled then there's something wrong with the structure of the car in the first place.
