Does anyone have any ideas/recommendations/sure-fire fixes, for retractable seatbelts that no longer retract properly?
It seems that most vehicles I own (largely Toyotas) always seem to develop problems with the seatbelt not retracting properly after about 120-150,000kms.
I've pulled the cover off the seatbelt retractor and squirted silicone lube into the retractor drum pivot point/bearings - but it seems to make little difference to them.
Do the seatbelts need to be discarded, or can you buy new retractor springs for them, or is there some other trick, that is an easy fix.
This problem is extremely annoying, and I'm sure I'm not the only one having it.

Cheers, Ron.

Hi Ron,

Very few people are aware that seat belts .... like ALL nylon webbing products have an active life.

There is no quick fix.

The whole belt assembly needs replacement.

Regards,
Wayne & Sally.

In a word - replace them mate.

Don't buy a lottery ticket Ron. You must be an unlucky one. We have never had any troubles with the seat belts in our cars. Even though we hang on to cars for 15 to 20 years. Any brand at all. The current Toyota and Nissan have both done over 250,000 kms and no hassles.

I would just replace them.

Hi Ron,
While I am sure this is frustrating, you cannot buy parts for seatbelts, if they are faulty in any way they must be replaced. Just remember they may save your life one one day. Stay safe

you can spray the underside of the belt webbing with silicon spray
it works pretty good

A little tip a pit inspector gave me once.
Give the whole belt a good scrub with White Spirits.

He suggested that, generaly, the drag from dust, dried sweat, body fats etc was more the problem than the spring.

Worked for me.


Cheers.....Lionel.

Ron,
I had the same with my 80 series driver side belt and it was fraying too.
There is a crew in Perth who are the only accredited seatbelt repairer in Australia and they do aircraft belts. I removed the whole seatbelt, top to bottom, and posted it to them on a Monday morning. It was back re-belted and working perfectly by Friday at a cost of, I think, about $120.
I have just dug up the invoice.

Cost $110 incl Postage in March 2014
Really good people to deal with.

Thanks fellas for the advice. I understand seatbelts are a bit of a touchy area and no-one should be playing with taking them apart and putting them back together again, particularly if they have no idea of what they're doing.
The insurance/liability angle is a concern if one pulls a mechanism apart and the vehicle is later involved in an accident, and the repair is discovered to have had some consequential result in the accident.

It appears that the drag from dirty seatbelts (which don't necessarily appear dirty - but which get coated in dust and body oils, which affects their slipperiness) is one of the major areas where the problem starts.

The other problem area appears to be the top belt support bracket, which the belt slides through, and where the belt effectively has to go through a 270-320 degree articulation as it slides through.
Apparently, the edge of the bracket where the belt slides over it, is prone to losing its slippery coating, and developing a sticky surface.
Not much one can do with that, I'd say, that would be a replacement deal.

Whirlwinders advice is excellent, that crowd is only 4kms from where I live and only a kilometre from my workshop, so if I can't get some better results from a belt cleaning session, I'll be paying them a visit.

Cheers, Ron.

As others have said, a good clean of the webbing will often help.

If you're removing the belt assembly for what ever reason, just be aware that most newer vehicles have seat belt pre tensioners fitted as part of the airbag system. These need to be handled with great care as they are extremely dangerous if accidentally activated.

Hi Ron,

Prudent behaviour would be to replace the entire mechanism+belt as others have said, however I have serviced a couple of mechanisms in the past successfully.

Certainly, some friction can come from the loss of sliding surfaces between the belt and top support bracket etc. but also the belt takeup spool and spring run on a lubricated axle which can become gummy with time. I have cured this by removing the assembly from the vehicle and washing with solvent then re-lubricating. I think most of the friction was from between the coils of the clock spring. No dismantling of the assembly was undertaken. They then operated smoothly and locked with the usual quick tug.

Simply squirting lubrication into the mechanism will not overcome the gummy lubricant within the assembly.

I am not too sure about applying lubricant or solvent of any type to the belt itself. You cannot be sure that it will not react with the belt material and weaken it.
Cheers
Allan

HI
Apply Baby powder may, may not work ,basically the retractor spring mechanism is on the way out . Typically u are only buying time and the best solution is replacement . The drivers seat is mostly the culprit . Either have repaired as per previous poster or replace.

Many GU patrols suffer this problem and the fix has been to scrub the underside of the belt with soap and water particularly the area that slides through the bracket fixed to the door pillar.Has worked for me.
