Seat belt fixing.

[blazinzuk]

Anyone familiar?


The weighted things are what lock the seatbelt. Problem I was having is the one on the right was locking all the time. I glued the pad to the weighted plunger. It still locks but it won't lock when you pull the seat belt out really fast. Still locks with just slight movement.

I'm just wondering if i am preventing it from operating. I can get it to lock by hitting it when extending it. So I think I'm good.

Better than no seat belt I am thinking

Can't download the pic due to my internet problems. But, there are two types of locks. One locks when the seat belt roller turns fast, but most of the American type belts don't lock that way. I knew all my Ford vehicles don't.
Instead, the little lead weight swings over whenever there is any sudden acceleration in any direction, such as hitting something or being hit by something
Which means you can pull the belt as fast as you want and it will not lock.
The way I test these, is get going at a fairly fast speed, grab the belt, and try to pull it out while hitting the brakes.
It should lock.
The one of my father's truck was bent slightly, and would lock when driving down a bumpy road.
That would cause the belt to get tighter and tighter with each bump.
Just look at the weights, and if they are not involved with the rotation of the belt, but cause it to lock when you swing them over, then they are that type.
Someday, I may get my speed back and can see what I am talking about.

@Fordum

They are the weighted ones . The weighted rod has a small pad that was not attached to the metal plate that locks the belt. They are 2 weighted rods. Neither were permanently attached to the metal locking plate. I attached one weighted rod to the metal locking plate.

It seems to work as it should. I pulled the belt out while simultaneously hitting the assembly with my hand. Just hitting it with my hand caused it to lock a couple of times. It did not lock every time but if the slight force from my hand can lock it I do think I will be fine

The ones on my Ford, had a weight on a rod that hung down through a hole in a plate. On top of the plate was a round disk on the end of the rod that lay flat on that plate. The locking plate lays on top of that disk which has a flat surface. When the weight swings in any direction, the edge of that disk lifts up the locking plate and it locks the reel. There was some kind of a little taper on the bottom side of that disk that kept it centered in the hole.
On my truck, the locking plate just lay flat on the weight disk and was not glued. I think it either had a very weak spring that held it down or was fairly thick and heavy.
To test the action before I tried it in the truck, I simply took my finger and swung the weight to any side and watched the locking plate raise up and lock.

Of course, that was a Ford, and an '89 model at that, I'm sure yours is at least a little different. If I remember right, the problem with mine was that the weight was not hanging straight down when it was in the truck. The bracket or something was bent some way.
I was working on it in about 1990, so its a little fuzzy. I could tell you exactly if I had it in front of me.

That's exactly like mine ( also an 89 btw)

There is a small black pad on top of the weighted rod. That is what touches the locking mechanism. You had to pull the weighted rod down to get it to unlock.

I don't know if it was time or wear, but the pad and rod caused it to lock all the time

I glued the pad to the locking mechanism. It will lock with a very slight movement still but it's a bit more than the locking mechanism right next to it. In this belt there are separate locking mechanisms for the shoulder section and lap section
