I was going to let this pass because of the consensus of opinion on the subject ;

But intertia reel seat belts has been the subject on many occasions before because an inertia reel seat belt has an "snatch" effect just like a block and tackle. It doubles the force on the top mounting.

Now, clubbies have especially strengthened 'B' pillars and areas for both the mounting of inertia reel belts as well as a burst proof door lock. I know, most mini doors get ripped off from the front hinges.

Earlier minis do not have this structural development and fitting inertia belts to these minis could buckle the "B" pillar inwards. It could also cuase insurance problems.

I am suprised Doc and Aaron did not comment on this.

I've never noticed any difference in the top part of the B Pillar. Obviously there is an extra mount in the rear storage bins of Clubmans for the reel.

Fitting inertia reels to roundnose cars necessitates using a single bolt for both the reel and lap strap end. I was told by an engineer this is quite legal (provded the car is structurally sound). Indeed some cars come this way from the factory. eg: The last of the Datsun 1200 utes.

I am glad you brought this up, not many years ago many early cars were being knocked back at rego for exactly this problem and i wondered if it is still the case that early cars needed a engineers report for the conversion as these seatbelts and there mountings are subject to ADRs

Mike - you may be right but if a manufacturer sells an inertia seat belt and labels the package "suitable for Minis all models 1960 to when ever" then where does the DIY installer stand? Also if a car is in an accident where that much force distorts the B pillar the car would be totalled and I don't think they would be looking too closely at seat belt anchorage points in relation to inertia or plain belt being fitted.

Last time I tried to buy seat belts (rear seat belts for a morris 1100) through both Repco and AutoOne they told me they couldn't sell them to me, they had to be sold through and fitted fitted by a licensed seat belt fitter. The is NSW I am talking about.

David - you make good points but if its an accident where a life is lost it becomes an matter for the coroner and the vehicle undergoes a forensics inspection. The owner of the car could be charged with manslaughter if non engineered seat belts are fitted.

I know there has been many threads on inertia reel belts in earlier minis on Ausmini.

Your car has a compliance plate that says what sort of seatbelts should be fitted and what anchorage points are rated to, no car before compliance plates was rated for anything but fixed belts, even holdens and fords needed to have the anchorage points certified by a accredited engineer

I don't think you will find any seatbelts marked as you suggest as they know there legal obligations and you can bet they run it by there legal people before evr selling something that involves automotive safety items

I've found that the min had two types of inertia reel belts. One where both the reel and a anchorage point is on a small braket with one bolt, which sits next to the seat. And the type which goes in the rear storage bucket. I have one of each and they both came from wrecked clubmans, but the ideal typer for the roundy (single bolt one) had a slightely torn belt so yeah threw that one away.

Here's the site selling Klippans, they list 1 belt only for models 1967 to 1982.

Therein is the problem - 1967-1982 My car is 1963 so without saying in as much detail the belt is not suitable as it is outside the range

Mate you cna still do it but you will need to get the attachment points engineered to be fully legal, there was a thriving biz in this in the late 70s early 80s for all those putting belts in there xr fords and early holdens and the like

I've mentioned this in other posts but I still can't get over the fact that my 63 model 850 has the 3 anchor points per front seat while my 64 model back in 1965 didn't have any points and when I installed the seat belts back then I had to drill the holes in the floor and use the provided square plates under the floor bolts and drill the B pillar and use the provided spacer and put the bolt right through the pillar

I have a 1970 model, the upper B pillar structure where the mounting is, is the same as a Clubby. They were strengthened internally around 1968. Previous ones were not as strong, I agree. I'd be careful putting inertia reels in those.
