Inertia reel belts

Recommended Posts

I know this has been done to death but mainly with regard to MX5 seats. I have moved away from the 'dark side' and replaced my MX5 seats with restored TR4A ones (I've yet to undertake a long journey yet so the jury is still out).

However the upper mounting for my 3 point static belts is placed such that the cross belt constantly slips off my shoulder unless I have it so tight I can scarcely breathe.

My questions are:

1. Which model of belt should I choose (I'm erring towards the type that are adjustable for angle)

2. Precisely where should I place the mountings

3. Which stalk should I choose (The Stag I used to have had stalks that were really too long and were a pain).

I am attaching pics of the current set up

Any advice would be welcome

The top mount should be on the rear wheel arch, as shown in the WSM

Thanks. That's what I thought. However, there seems to be no mention of seatbelts or mountings in my Workshop Manual (510322 2nd ed. 1965 though my car is 1962)

Although it’s referring to lifting the body this is where the original seat belt mounts were on early cars.

I would still welcome advice on which inertia system would be the best and precisely where the various mountings should be located bearing in mind it is a TR4 with no rear seat squab

If you dont mind new style belts then Securon 500/30 will do fine http://www.securon.co.uk/seatbelts_layouts.htm

Fit the reels to the bottom sides of the rear arches and then at the top of the arch fit the other bracket the belt slides through and the bottom fastener is in the base of the "B" post. The stalks bolt through the rear sides of the tunnel on a TR4.

If your feeling flush and want period type belts then these guys are very good. https://www.quickfitsbs.com/classic_cars_seatbelts.php

Many thanks Stuart.

Would it be advantageous to fit the 514/30, Stuart? I assume the slide bracket would need to be slightly angled towards the outside shoulder area. I don't suppose you have a pic of this top bracket in situ.

I have used those but as the reels are only handed one way then one side sits nice but the other has to sit further out to clear. The reels for them would be mounted on top of the arch and only really suit a Surrey top car otherwise they can be a bit in the way of the hood mechanism, its doable but they do intrude a bit.

I dont have pictures Im afraid.

Thanks again. How strange that they are only handed one way.

As you can see from my pics, the bottom fastener is somewhat forward of the base of the "B" post and the stalks (in my case straps) are located on the floor next to the tunnel. As I don't really want to change the perfectly acceptable carpets and weld the holes up, could I get away with keeping these where they are?

I suspect the inner floor ones maybe OK as theyre probably screwed into the chassis (I would check to make sure that is so or that there is a sufficiently large re-enforcing plate underneath it) and the same applies to the other, however due to its location the outer floor one is not ideal for any inertia belt fittings. I would check to see of you have the original lower fixing points which were re-enforced from the factory. One at the base of the "B" post and one at the rear side of the tunnel and if present go back to them and just add a grommet with a bit of sealer to the others.

Stuart.
