Seat Belts

I purchased this vehicle with the intent of hauling passengers.  This goal was disabled by rear seat belts that did not tighten across the front of the passenger.

Assumed problem: Broken retractor springs
Relaxed position, any orientation (Can you tell it doesn't work?)

Check out the Tri-Wing heads!
Actual Problem: disconnected retractor spring.




Reattached retractor spring (added bend to tip to prevent future disconnect)

Manually disable orientation lock in order to re-wind spring

I re-wound the spring by disabling the orientation lock and rolling the belt back onto the assembly.

Final product: Properly operating seat belts. Praise the Lord!

  1. When you first noted the problem of not rewinding, was it actually winding not at all or was it rewinding weakness?
    the latter is the problem in my 740 GLE TD OD

  2. Dan,

    My seat belts were not operating at all, because the spring was completely disconnected from the shaft.

    I recommend fully extending the belt, then removing the spring cover, and disconnecting the spring from the shaft. Preload the spring by winding it a few times before re-engaging it onto the shaft. Then wind the spring as mentioned above. This should increase the preload enough to compensate for the reduced spring rate. After reinstalling the belt into the car, the increased belt tension should be evident.

    Let me know how it goes.
