- Restraints).
This bulletin is being issued to provide information to the customers if they comment that the left or right front seat belt may appear to not release from
the retractor when trying to put on the seat belt.
A Description For Your Customer
This condition generally does not require replacement of any parts. This condition is the result of allowing the belt to enter the retractor at a high rate of
speed. If the belt is allowed to go all the way back into the retractor very quickly, it is possible that the force of the belt stopping suddenly against the
seat back will vibrate the retractor. This vibration "fools" the retractor into thinking that the vehicle is changing velocity. The normal function of the
retractor under this condition is to lock the belt.
How to Correct or Eliminate the Condition
The only way to completely eliminate the condition is not to allow the belt to retract back all the way into the retractor quickly. The fast retraction
usually occurs when the customer holds the latch while unbuckling and guides the webbing into the retractor quickly until it's fully stowed. As long as the
customer guides the belt at a slower rate of speed, the retractor will work consistently without locking. Also, if the customer unbuckles the belt and lets
the webbing retract on its own (without guiding it), there is generally enough friction from the belt against clothing to slow down the belt so it won't lock
when it fully stows.
If the customer does allow the belt and latch plate to retract quickly, the retractor can easily be restored to normal operation. Simply pull on the belt to
create some slack in the webbing and pay back some of the webbing into the retractor. Slack can also be created by pushing on the foam at the top of the
seat back. After a maximum of 10 mm (0.39 in) of webbing is introduced into the retractor, it will unlock and function again. Please demonstrate this
action to your customer. After an explanation and demonstration, most customers should be able to unlock the retractor without a problem. You may give
a copy of this bulletin to your customer for further reference.
